Microsoft Removes WMIC from Windows 11 After Years of Abuse as LOLBIN by Ransomware and Attackers
Microsoft has begun permanently removing the legacy WMIC command-line utility from Windows 11, starting with versions 24H2 and 25H2. The tool is no longer available in fresh installations, has been dropped as an optional component, and is absent from the latest beta builds. WMIC provided text-based access to Windows Management Instrumentation for querying hardware, processes, services, and security software, as well as performing administrative tasks. Although the underlying WMI technology remains untouched, Microsoft has deprecated the command shell due to its long-standing use as a LOLBIN in cyberattacks. Ransomware operators have leveraged WMIC to delete shadow copies and hinder recovery, while other attackers used it to enumerate and disable security tools or add exclusions in Microsoft Defender. Administrators are directed to migrate to PowerShell, COM API, .NET libraries, and modern scripting languages, which will require rewriting legacy automation scripts.
Octagon Malware-as-a-Service Platform Targets Android Banking Apps and Crypto Wallets for $1400 Monthly Subscription
Researchers at iVerify have uncovered the previously unknown Octagon platform, a malware-as-a-service offering sold by a Russian-speaking actor under the handle AndroidKitKat. The service first appeared on underground forums on June 1, 2026, with version 1.2 released by June 29, providing a ready-made control panel for account takeovers across banks, crypto exchanges, messengers, and wallets. Infection starts with a disguised APK that requests Accessibility Services permissions, after which the trojan can read UI elements, simulate taps, launch apps, and overlay phishing screens on services such as Trust Wallet, Binance, and MEXC. The malware also intercepts SMS one-time codes, spoofs the system lock screen to steal PINs or patterns, and supports VNC-style remote control while operating on the victim’s own device to evade anti-fraud systems. Three related builds—Octagon, Lifted Dreams, and BahrDate—were identified, with one variant displaying a visual novel to distract users while the spyware runs in the background. The campaign underscores the growing threat of sophisticated Android remote-access trojans sold on a subscription basis.
BTMOB Platform Turns Android Banking Trojan into Customizable Fraud Campaign Constructor
Researchers at QuimeraX have uncovered BTMOB, a platform that evolved from a banking trojan into a full-featured builder for fraudulent Android campaigns. The service allows clients without development skills to select an app name, icon, command-and-control server, permissions, and social-engineering lure, after which the system automatically compiles a ready-to-use APK. The package includes an Android payload, dropper, VB.NET control panel, PHP and MySQL backend, and build tools that enable rapid production of localized copies of streaming services, banking protection modules, parcel trackers, and social networks. One BTMOB 2.5 variant was distributed via a phishing site mimicking the Turkish iNat TV service, while Brazilian operators created fake Google Play pages impersonating Nubank, TikTok, and the government portal Gov.BR. After installation, the trojan requests accessibility permissions and, once granted, grants operators near-complete device control including screen viewing, keystroke capture, audio recording, and real-time WebSocket interaction that lets attackers perform actions directly on the victim’s device. Analysts link BTMOB to the SpySolr family and earlier commercial RATs CypherRAT and CraxsRAT, which had already attracted more than 100 licensees.
Dysphoria Botnet Compromises Nearly 300,000 Devices for DDoS Attacks and Residential Proxy Services
The Dysphoria botnet has infected approximately 296,000 devices, including routers, IP cameras, gateways, and embedded Linux systems. Researchers first observed the threat in the first quarter of 2026, noting rapid evolution from the jackskid and fbot families. The infrastructure is primarily used for DDoS attacks but has expanded to offer residential proxy capabilities. Infection occurs through brute-force attacks on Telnet and SSH services with weak credentials, as well as known remote code execution vulnerabilities in IoT equipment. A key technical advancement involves the use of Ethereum and Solana blockchain domains for command-and-control infrastructure, making takedowns significantly harder. Compromised devices can also function as relays by leveraging UPnP to expose ports and hide criminal traffic origins. Operators advertise attack capacity of up to 4 Tbps and sell DDoS services in structured commercial packages targeting internet services and gaming platforms worldwide.
TRON, Aptos and BSC in One Infection Chain: JavaScript Loader Linked to ChainVeil Campaign
Researchers at Checkmarx examined the ChainVeil campaign that used npm packages to distribute multi-stage JavaScript loaders. A newly discovered sample appeared in a GitHub repository recommended by an AI agent, where the file navigation.js contained an obfuscated loader that matched the campaign's techniques. The loader retrieves encrypted payloads from TRON, falls back to Aptos, and then uses the extracted data as a BSC transaction identifier to fetch the next stage. C2 infrastructure and final RAT functionality aligned exactly with previously published indicators, except for the campaign identifier A9-0554-3 instead of the A6-* markers seen in npm samples. Git history showed the malicious code was inserted via a merge commit on 29 March 2026, months before the first known npm packages appeared in May. The findings indicate that npm was never the only distribution channel for ChainVeil and that the campaign's blockchain-based delivery mechanism has been active since at least early 2025.
Malinsure Cybercrime Group Deploys SafeMostSSH Backdoor via Phishing Lures Mimicking Russian Insurance Updates
Researchers from F6 identified a previously unknown cybercrime cluster named Malinsure that has been active since at least July 2026. The group distributes phishing emails containing PDF lures themed around voluntary medical insurance (DMS) discounts and updates from Russian insurance companies. Victims are tricked into downloading RAR or ZIP archives that abuse legitimate Microsoft binaries such as winword.exe and powerpnt.exe through DLL side-loading to execute the custom SafeMostSSH backdoor. The malware establishes a persistent reverse SSH tunnel to attacker-controlled servers and retrieves fresh C2 addresses from public posts on vc.ru by decoding fake PNG links. Additional delivery vectors include HTML and SHTML files that decode and drop archives containing the same payload components. Targets appear to include insurance, finance, and fuel-energy sector organizations, with infrastructure also referencing gosuslugi.email and minfin.support domains.
Compromised Chromium Extensions Push Malware Through Fake Critical Update Alerts
Users of Chromium-based browsers including Chrome, Brave, and Opera have encountered persistent pop-up windows demanding immediate browser updates. These alerts originate from compromised extensions that dynamically load malicious VBS scripts or EXE files instead of delivering legitimate updates. The deceptive messages appear during normal browsing and instruct users to download and manually execute suspicious files. Earlier incidents were traced to the QuickLens extension, while current reports implicate Enable Right Click & Copy Smart Unlock + OCR and similar utilities still available in the Chrome Web Store. Attackers achieve persistence by purchasing popular extensions or hijacking developer accounts to push malicious updates. Full system scans often fail to detect the threat because the browser itself remains clean until the user triggers the payload. Security experts recommend verifying updates exclusively through the browser's built-in menu rather than clicking any on-screen prompts.
Palo Alto Networks Unit 42 Uncovers Kimwolf v7 Botnet Infecting Android Set-Top Boxes via Open ADB
Researchers at Palo Alto Networks Unit 42 have identified Kimwolf v7, an updated botnet that compromises Android set-top boxes and other IoT devices to conduct DDoS attacks. The malware now employs HTTP/2 flooding with realistic browser fingerprints to blend malicious traffic with legitimate user activity. Command-and-control infrastructure is hardened through Ethereum Name Service lookups and public Ethereum RPC services, with a Tor fallback address embedded in the binary. Operators have removed scanning, exploitation, and brute-force capabilities from this version, indicating a division of labor where a separate loader handles initial infection. The botnet uses 15 numbered methods focused on high-performance UDP floods optimized for ARM processors. Infections typically occur through residential proxies targeting devices with open Android Debug Bridge on port 5555, after which the malware masquerades as system processes. Unit 42 advises treating Android set-top boxes as untrusted devices and disabling ADB or restricting it to USB access only.
Google Play Apps Hide Anatsa Banking Trojan Using Stealthy Loaders
Malicious applications distributed through Google Play are employing stealthy loaders to install the Anatsa banking trojan for Android, putting victims' financial accounts at risk. The campaign relies on seemingly legitimate programs to conceal the initial infection stage, with one identified case involving a modified PDF reader that displays a fake update prompt to trick users into installing an additional component. Another loader discovered in the Cleanova application collects data from analytics SDKs, including installation source details, and forwards this information to a command-and-control server. The server then decides whether to deliver the malicious payload based on predefined criteria, leaving the code inactive for non-targeted victims to evade automated analysis. Once Anatsa is installed, the threat can facilitate theft of credentials used for financial services and enable fraudulent transactions. Banking trojans represented 30.77 percent of detected malicious mobile applications in the second quarter of 2026, during which more than 1.99 million attacks involving malware, adware, or unwanted programs were blocked and 93,574 banking trojan installation packages were identified.
Android Banking Trojans Hide in Droppers to Bypass Google Play Checks
Kaspersky solutions blocked 1.99 million attacks involving Android malware, adware and potentially unwanted programs in the second quarter of 2026, down from 2.68 million the previous quarter. Researchers still recorded 304,000 malicious installation packages, among them 93,600 banking trojans that retained the largest share at 30.77 percent. Operators increasingly rely on droppers that pass initial store review and later download the real payload. One PDF reader application distributed through Google Play displayed a fake update prompt that installed the Anatsa banking trojan. The Cleanova dropper collected installation-source data and delivered its payload only under attacker-chosen conditions, avoiding analysis environments. The share of users hit by Trojan-Dropper.AndroidOS.Banker.dd rose sharply from 0.01 percent to 2.16 percent, while the Mamont and Creduz families continued to expand with new variants.
Reverse Engineering Tutorial Explores Hybrid Analysis of Linux x86-64 Crackme Using Ghidra and GDB
A detailed three-part tutorial series examines the crackme binary Getting started keygen by Mazzotti on Linux x86-64. The first installment covers initial file inspection with file and strings utilities, identification of the ELF format and PIE properties, and loading the stripped binary into Ghidra to locate the entry point and main function. Analysts reconstruct stack frames, resolve optimized prologues, and correct Ghidra's variable sizing errors through dynamic confirmation in GDB. The series emphasizes hybrid static-dynamic methodology: decompiler hypotheses are tested with breakpoints and memory examination, then fed back to refine types and structures. Future parts will cover mutation testing, hidden C++ structures, and full Python reconstruction of the validation algorithm without patching branches.
DDoS-Guard Reports Record 540,000 L7 Attacks in June 2026 Amid Botnet Fragmentation
DDoS-Guard recorded a sharp 70% increase in L7 attacks during Q2 2026, with June alone seeing 540,000 incidents. Global volumetric attacks doubled compared to all of 2025, including peaks of 1.64 Tbps and 1.58 Tbps. Law enforcement dismantled four major IoT botnets—Aisuru, KimWolf, JackSkid and Mossad—in March, yet long-duration L7 campaigns surged 380%. Attackers shifted focus to application-layer exhaustion using browser automation and AI agents while targeting HR platforms and news sites. Europol’s Operation PowerOFF led to 75,000 warnings and 53 domain takedowns across 21 countries. Experts attribute the June spike to attacks aimed at protection providers themselves rather than single domains.
Spyware-Laden Modified iOS Apps Distributed via Russian Telegram Channel, Kaspersky Discovers
Kaspersky researchers have identified modified versions of popular iOS applications that are being distributed through a Russian-language Telegram channel and contain a malicious spying module. The infected apps include a marketplace platform for selling goods, a photo editor, and a video viewing service, all offered as ad-free versions with extra free features. Attackers embed the spyware directly into legitimate IPA files, while some clean apps simply promote the same channel to funnel users toward the malicious downloads. Installation requires users to obtain a developer certificate and sign the app using tools such as eSign or Scarlet, or to sideload via a computer or jailbroken device, completely bypassing the App Store. Once launched, the malware collects device name, battery level, regional settings, memory information, jailbreak status, geolocation, carrier code, and screenshots before sending the data to the attackers, although it stops when the app is closed. Kaspersky advises users to obtain applications only from official stores or verified developer websites rather than random Telegram sources.
DarkSword Exploit Kit Expands to 180 Sites Targeting iPhone Users with Zero-Click Chain
The DarkSword exploit kit has scaled its infrastructure to 180 web properties hosted on 27 servers, enabling zero-click compromise of iPhones running vulnerable iOS versions. Attackers deploy fake pages impersonating Apple, AWS, and other popular services to trigger a six-vulnerability exploit chain that achieves remote code execution, sandbox escape, and privilege escalation on iOS 18.4 through 18.7. Once the device is compromised, GHOSTBLADE components extract data from the Keychain, iCloud files, Wi-Fi passwords, and other stored content before exfiltrating it to attacker-controlled panels. The malware deletes crash reports and forensic logs to hinder analysis and does not establish traditional persistence, limiting the window of data theft to a single visit. Infrastructure rotates rapidly, with five of seven administrative panels observed on July 30, 2026, having appeared only a week earlier, indicating frequent domain and host replacement to evade blocking.
Octagon Android RAT Poses as Bahrain Emergency Alert App to Steal Credentials and Establish Persistent Surveillance
A remote access trojan named Octagon targets Android devices by masquerading as the official emergency alerts application from Bahrain. The infection begins when victims download the BH-Alert.apk file from phishing websites. The malware guides users through seven steps to grant dangerous permissions while using encrypted code hidden inside a font file extension to evade static analysis. It installs a secondary component called OctagonPanel and deploys mutual-monitoring surveillance services that restart each other if terminated. Additional persistence is achieved through boot receivers, a fake Android account, and scheduled synchronization tasks every 30 minutes. The trojan abuses the Accessibility Service to record unlock patterns, PINs, and passwords while also harvesting SMS messages, contacts, call logs, and screenshots. A criminal-controlled VPN allows interception and redirection of victim traffic.
Distributed Crawler Poses as Human Visitor to Evade Analytics and Ad Filters
A detailed investigation revealed a sophisticated distributed crawler that successfully mimicked legitimate human browsing behavior across multiple unrelated websites. The crawler generated realistic events in Google Analytics while avoiding ad script loading and resource chains that would confirm genuine user sessions. Server logs showed consistent patterns of fake search engine referrers, internal navigation with fabricated Referer headers, and selective requests limited mostly to images returning 404 errors. Analysts built a graph-based detection system that correlated events across sites to expose the coordinated activity despite individual requests appearing benign. The campaign rotated browser signatures and IP addresses frequently, making single-site rate limiting ineffective. The case demonstrates how modern crawlers can exploit Measurement Protocol and incomplete bot detection to consume server resources without contributing to revenue.

A detailed roundup of professional literature covering malware development, reverse engineering, and defensive analysis has been published. The selection includes resources focused on Windows, macOS, and Android platforms. Key titles address practical techniques for building and dissecting malicious software, evasion methods, and forensic investigation. Books such as MalDev Academy and Practical Malware Analysis provide hands-on training with real-world samples and laboratory exercises. Additional volumes explore macOS-specific threats and Android malware detection using machine learning. The compilation aims to support both red team practitioners and malware analysts in deepening their technical expertise.
Bots Now Form Over Half of Global Internet Traffic in 2025, Driving API Attacks and Business Metric Distortion
Automated clients generated more than 50% of analyzed internet traffic in 2025, with malicious bots responsible for 40% of the total volume. AI-enabled automation attacks increased 12.5 times year-over-year, while daily API attacks rose 113% according to Akamai data. Simple scripts still dominate volume at 59% of bot traffic, yet sophisticated botnets exceeding 4.5 million devices now distribute activity across residential proxies and compromised endpoints. Credential stuffing, scraping, and transaction abuse continue to target business logic rather than software vulnerabilities, distorting analytics, inflating infrastructure costs, and degrading user experience. Cloudflare reports that 20% of verified bot traffic now comes from AI crawlers, blurring lines between beneficial and harmful automation. Organizations must classify bots by intent, delegation, and business impact instead of relying on IP reputation or single signals such as User-Agent strings.
Astaroth Trojan Hijacks WhatsApp Web Sessions to Spread Banking Malware to Contacts
The operators of the Astaroth banking Trojan, also known as Guildma, have added a new module that turns infected Windows systems into automated spam bots for WhatsApp Web. The malware copies browser profiles from Chrome or Edge, launches a legitimate WebDriver instance, and connects to an already authenticated WhatsApp Web session using the WPPConnect/WA-JS library. Once active, the bot scans the victim's contact list and sends each recipient a personalized greeting, a ZIP archive containing the Astaroth loader, and a closing message, all generated with randomized phrasing to evade detection. The technique leverages the trust users place in messages from known contacts, significantly increasing the likelihood of successful infection. Researchers at CrowdStrike note code similarities with tools used by other Latin American groups, including Vareg, suggesting shared development or active exchange of components. Indicators of compromise include PowerShell downloads of WebDriver, creation of ChromeAuto_ folders in C:\Users\Public\Temp, headless Chromium execution, and network activity tied to WPPConnect components.
Flying Eagle Android Trojan Turns Devices into Remote Surveillance Tools
Researchers at Hunt.io have analyzed the Flying Eagle Android trojan, which spreads via fake public security bureau apps hosted on counterfeit sites. Victims are tricked into installing the APK and granting Accessibility Services permissions, after which the malware effectively takes control of the device. It performs keylogging, screenshots, phishing overlays on banking and government apps, SMS interception, and remote camera and microphone activation. Operators use the dispatchGesture API to remotely control the interface and press buttons. The platform functions as a full surveillance factory with a unified panel for building customized APKs, managing infected devices, and collecting stolen data. After source code leaked in February 2026, builds are sold on Telegram for around 2000 USDT, with Night Dragon emerging as an enhanced successor targeting Alipay, WeChat, banking apps, and crypto wallets.
Tengu Botnet Modernizes Mirai with 25 DDoS Methods and Advanced Persistence on IoT and Embedded Linux
A new botnet named Tengu has emerged, targeting Internet of Things devices and embedded Linux systems to conduct denial-of-service attacks, redirect traffic, and maintain persistent access. The malware represents an updated evolution of the Mirai botnet and begins its infection chain through brute-force attacks against exposed Telnet services. Once valid credentials are obtained, it downloads an architecture-specific payload and establishes partially encrypted communication with its command-and-control server. Operators can issue commands to collect system and network information, update the implant, and convert compromised devices into SOCKS5 proxies. The botnet includes 25 distinct DDoS attack methods covering UDP, TCP, and ICMP floods while also targeting services such as HTTP, DNS, NTP, SSH, SMTP, FTP, SIP, Minecraft, and servers running Source Engine or Quake protocols. Its key differentiators lie in robust persistence and self-protection mechanisms, including a secondary watchdog process that restarts the malware every 60 seconds if terminated, fake systemd services, manipulated device watchdogs, and the ability to remove competing malware.
Cybercriminals Hide Malware in Fake Claude Code Installation Command Targeting macOS Developers
Cybercriminals are distributing the MacSync infostealer by embedding malicious commands in fake installation tutorials for Claude Code. The campaign relies on sponsored search ads and counterfeit documentation pages that appear when developers look up official setup instructions. Victims are instructed to paste an obfuscated command into the macOS Terminal that uses Base64 encoding to conceal the download server and disables certificate validation. Once executed, the command retrieves MacSync, which steals passwords, session cookies, SSH keys, cloud credentials, and developer configuration files. Stolen tokens can bypass multi-factor authentication and grant attackers direct access to accounts and repositories. Security experts advise installing Claude Code exclusively through official channels and immediately isolating any compromised Mac while revoking all sessions and rotating credentials from a trusted device.
Automating Malware Reverse Engineering with Local LLMs, PyGhidra and Neo4j Graphs
A researcher has developed an automated pipeline that uses local large language models to analyze decompiled malware code extracted via PyGhidra. The system loads functions, call graphs, strings and imports into a Neo4j graph database to preserve context across hundreds of functions. Each function is sent to a local Qwen3 model running in LM Studio together with its neighboring call-graph context, producing structured JSON output on purpose, IOCs, tags and evasion techniques. Aggregated capabilities and behavioral patterns such as file encryption and C2 communication are then derived through graph queries. Testing on a WannaCry sample from MalwareBazaar processed 195 functions in 126 minutes and correctly identified File Encryption, C2 Communication and Anti-Analysis behaviors with 100 percent confidence. The approach keeps all sensitive indicators inside a local environment and avoids context overflow and censorship issues common with cloud-based models.
GitHub Removes 10,000 Malware Repositories After Public Exposure but Takes No Further Action
An investigation reveals that GitHub hosts thousands of repositories distributing trojanized ZIP archives, many of which have persisted for two years despite the platform's resources. The malicious repositories follow consistent patterns in README files, including specific headings and links to versioned archives hosted on githubusercontent.com. A detailed article and accompanying script published on Hacker News identified over 10,000 such repositories, prompting GitHub to delete only those specific entries. New repositories matching the same patterns continue to appear and remain active, with no additional proactive measures taken by the security team. The situation highlights questions about Microsoft's approach to automated detection and response on its subsidiary platform.
Dolphin X Malware Adds AI Profiler to Rank and Prioritize High-Value Victims After Infection
Dolphin X is a newly identified Windows infostealer and remote access trojan that integrates an AI Profiler component designed to score infected machines and generate priority rankings for operators. The profiler analyzes telemetry from compromised systems, including application usage, browser domains visited, and installed software, to produce daily summaries that help attackers focus resources on the most valuable targets such as those with cloud access or sensitive tools. Dolphin X claims compatibility with over 300 applications, explicitly covering nine Chromium and Gecko browser families, more than 100 cryptocurrency wallet extensions, 65 desktop wallets, 10 password managers, and over 30 common cloud CLI tools. The malware targets files like .env configurations, SSH keys, cloud access tokens, browser sessions, and cryptocurrency wallet data to accelerate movement from initial credential theft to further compromises in accounts and production environments. Researchers have confirmed the AI Profiler workflow and associated scoring functions in the operator panel, although the underlying AI model itself remains unverified without full analysis of an active sample. The discovery highlights how automated prioritization can significantly shorten the time between mass infections and targeted follow-on attacks, prompting recommendations for reduced local credential storage and enhanced behavioral detection.
YARA Style Guide: Comprehensive Best Practices for Naming, Structuring and Maintaining Detection Rules
The article presents a detailed translation and adaptation of Florian Roth's YARA Style Guide, aimed at bringing consistency to large collections of YARA rules used by security teams. It explains how to construct informative rule names that include threat category, context, operating system, architecture, technology, packers and creation date, using prefixes such as MAL, HKTL, WEBSHELL, EXPL, VULN, SUSP and PUA. The guide recommends specific metadata fields including description, author, date, reference, score and hash, along with a three-tier string categorization system using $x*, $s* and $a* prefixes for high-specificity, group and preliminary strings. It also covers false-positive filters marked with $fp*, proper indentation, readable hex and string formatting, and a recommended order of conditions that begins with header checks and ends with false-positive filters. The publication highlights the benefits of this structured approach for long-term maintainability and faster triage during mass detections. Additional references point to the separate YARA-Performance-Guidelines project for deeper optimization techniques.
187,064 Instructions for One Flag: Reverse Engineering HTB Callfuscated Insane Challenge
A detailed technical breakdown of the HackTheBox Callfuscated reversing challenge reveals an extremely heavy obfuscation scheme built around a custom virtual machine, mixed Boolean-arithmetic transformations, opaque predicates, and call-based junk code. The binary implements a password checker that executes 187,064 instructions even on a short input because every real operation is wrapped inside thousands of call/pop gadgets. The author bypassed static analysis by building a ptrace-based tracer, dumping the 586-cell VM program array, and writing a Python emulator that faithfully replays the recorded execution trace. After fixing several edge cases involving rand() return addresses and operand-size detection, the emulator reproduced the exact register state of the original binary. Dynamic analysis exposed that the VM performs simple big-endian word construction followed by XOR operations with eight constant pairs, allowing the flag to be recovered directly without further symbolic execution.
HollowGraph Malware Abuses Microsoft 365 Calendars to Conceal Stolen Files and C2 Traffic
A newly discovered espionage malware called HollowGraph turns compromised Microsoft 365 calendars into hidden channels for receiving commands and exfiltrating stolen data. The implant schedules events for 13 May 2050, a distant future date chosen to reduce the likelihood of discovery by account owners. Developed as a Windows DLL, HollowGraph leverages the Microsoft Graph API to blend its traffic with legitimate corporate service activity, eliminating the need to contact attacker-controlled servers directly. It supports two primary commands: “get” to retrieve instructions attached to operator-created appointments and “send” to encrypt collected data with RSA and AES-256-GCM before uploading it as calendar attachments. Separate encryption keys are used for inbound commands and outbound data, while stolen files are written to a disguised logAzure.txt file. Researchers have identified at least 12 compromised systems, three of which remained active, with operations observed between 3 June and 9 July 2026 and primarily targeting Israeli entities.
ClickLock Stealer Locks macOS Until Victims Enter Real Passwords and Exfiltrates Browser, Crypto and Keychain Data
Researchers at Group-IB have discovered a new macOS infostealer called ClickLock that blocks normal computer operation until the user supplies valid account credentials. The campaign, active since May 2026, has already affected at least 100 victims across 33 countries. Infection begins with a fake Cloudflare verification page that tricks users into pasting a command into Terminal, after which the malware silently downloads four modules from compromised WordPress sites. A convincing macOS password prompt then appears; ClickLock validates the entered password locally and only forwards working credentials to the operators. Two persistent LaunchAgent modules repeatedly close all visible applications and force Keychain authorization, while a separate process disables Notification Center for several hours. The malware harvests data from eight browsers, 31 crypto-wallet extensions, seven password managers, eight desktop wallets, Keychain items, command history, FTP credentials and six blockchain addresses before exfiltrating everything via Telegram bots and hijacked domains, leaving behind a disguised GSocket backdoor.
New Russian Translations of Leading Cybersecurity Books on Ethical Hacking, Reverse Engineering, Malware Analysis, and Privacy Released
A popular Russian library project has published fresh translations of more than a dozen top-tier English-language books covering ethical web hacking, bug bounty hunting, network protocol attacks, binary reverse engineering, malware analysis, fuzzing, and privacy protection. The updates continue the long-running “Materials on Hacking in Russian” series, with all books made freely available through the Hackbooks platform. Titles include Web Hacking 101, Real-World Bug Hunting, the official Nmap guide, Attacking Network Protocols, a comprehensive beginner’s reverse engineering textbook, and specialized works on binary format analysis, obfuscation techniques, Windows security internals, Practical Malware Analysis, Evasive Malware, and The Fuzzing Book. Additional volumes address the history of state surveillance, Crypto Wars, and the societal implications of mass data collection. Each book entry features detailed descriptions, practical examples, and direct links to the corresponding Hackbooks cards, enabling Russian-speaking researchers and students to study advanced information security topics without language barriers.
TELEPUZ Malware Spreads via ClickFix Social Engineering, Targets Windows with Modular Capabilities and Resilient C2 Infrastructure
Since late April 2026, compromised websites have been distributing the new modular malware TELEPUZ through the ClickFix scheme. Attackers replace standard browser error fixes with instructions that trick users into pasting and executing a PowerShell command from the clipboard, which then downloads an intermediate loader, the Vidar infostealer, and finally TELEPUZ via rundll32.exe. The malware performs extensive environment checks to avoid sandboxes and debuggers before disabling Windows security features, escalating privileges, and persisting as a service inside svchost.exe. For command-and-control, TELEPUZ relies on WebSocket connections with multiple fallback mechanisms, including encrypted links stored in Telegram profiles, Steam accounts, DNS records, and a Polygon smart contract. It offers a wide range of capabilities such as file manipulation, keylogging, screenshot capture, process management, cookie theft from Chromium browsers, and arbitrary JavaScript execution in both Chromium and Firefox. Researchers at Elastic assess TELEPUZ as a malware-as-a-service offering still in early development, evidenced by a limited number of C2 domains yet frequent daily builds and rapid updates hosted on compromised sites in Brazil and India.
RedHook Android Trojan Automatically Enables Wireless ADB Debugging to Hijack Devices Without Root or User Interaction
The RedHook trojan, first identified in July 2025, has gained a novel capability that allows it to independently activate wireless ADB debugging on infected Android devices, granting system-shell privileges without requiring root access or any victim interaction. Infection begins through social engineering calls or messages impersonating bank or government officials, tricking users into installing malicious APKs hosted on legitimate platforms such as GitHub repositories and Amazon S3 storage. Once installed, the malware obtains accessibility service permissions and then silently navigates device settings, taps the build number seven times to unlock developer options, and enables wireless debugging. Leveraging code derived from the popular Shizuku tool, RedHook launches its own ADB client to connect directly to the local debugging server, bypassing the need for a computer. With elevated privileges, the trojan can install or uninstall applications, modify protected settings, grant itself permissions, and exfiltrate data and screen recordings over encrypted channels while employing multiple persistence techniques including mutual process resurrection and post-reboot restoration. Attacks have so far been concentrated in Southeast Asia, particularly Vietnam and Indonesia. Security experts recommend installing apps only from official stores and exercising caution with accessibility permission requests.
Fake Telegram Proxy Repositories on GitHub Deliver Stealer Malware to Home Users Seeking to Bypass Restrictions
Cybersecurity researchers from Solar 4RAYS at GC Solar have uncovered a widespread campaign where attackers distribute fake Telegram proxy tools on GitHub and mirror sites. The scheme capitalizes on Russian users searching for ways to circumvent Telegram restrictions, with malicious repositories quickly replacing legitimate ones in search engine results. Victims download trojans such as Salat Stealer or Santa Stealer that are disguised as useful proxy software, complete with copied README files, layout, and even the original developer’s donation details. These stealers extract browser sessions, passwords, and specific file types, potentially leading to account takeovers and data theft. The attack benefits from high user trust in GitHub, although the platform’s hosting service cannot always review the constant stream of new uploads. Experts warn users to avoid automatic downloads and to watch for warning signs such as brand-new accounts, zero stars or forks, and requests to disable antivirus software before installation.
