Local LLMs Enable Scams by Drafting Fraudulent Replies Without Warnings
Tests on consumer hardware showed that popular 7-8B local models almost never flagged classic advance-fee schemes when asked to draft replies instead of detecting fraud. The author ran 42 scam scenarios across Russian, Kazakh and mixed language on Llama 3.1 8B, Qwen 2.5 7B and DeepSeek-R1 8B using only an RTX 5050 laptop and Ollama. Without additional controls the models produced ready-to-send messages agreeing to prepaid transfers to unknown Kaspi Gold numbers in nearly every case. Introduction of the MoneyGate layer, which combines a mandate check, a separate judge model and hard-coded red-flag rules, blocked all 42 malicious requests while still allowing most legitimate payments to proceed. The benchmark KZ Scam Shield covering 12 Kazakhstan-specific fraud patterns remains publicly available for further testing.

How to Check If Your Passwords Have Leaked Online Using Have I Been Pwned
The article explains the common ways passwords end up exposed through site breaches, password reuse, or device infostealers. It details how to use the Have I Been Pwned service to check email addresses against known data leaks and the separate Pwned Passwords tool to verify if a password itself has appeared in dumps. Readers learn that absence from the database does not guarantee safety and that results must be interpreted by examining exactly which data fields were exposed. Practical steps include replacing reused passwords starting with email and financial accounts, enabling MFA or passkeys, terminating old sessions, and scanning devices for malware. The guide also recommends adopting a password manager and staying alert to login notifications. Overall it stresses that regular checks combined with unique credentials and multi-factor authentication form the most effective defense against credential stuffing and account takeovers.

Enodia: Open-Source Go Tool Automates Service Inventory, EOL Tracking and CVE Correlation
A DevOps engineer has released enodia, a single-binary Go CLI that discovers real versions of services across large heterogeneous environments and correlates them with end-of-life calendars and vulnerability databases. The tool was built after manual Ansible-based inventories and existing solutions such as endoflife.date, nvchecker, Renovate and Uptime Kuma proved insufficient for covering both infrastructure and application services while also providing actionable lifecycle, patch and branch status. Enodia uses product-specific probes for 123 technologies including PostgreSQL, MySQL, MariaDB, Jira, Confluence, Bitbucket, VMware vCenter, ESXi, pfSense and multiple Linux distributions, falling back to a generic URL-plus-regex probe when needed. Data collection is deliberately separated from evaluation so that inventory.jsonl files can be generated inside air-gapped networks and later analysed where CVE feeds are available. The project also contributed dozens of missing products and corrected EOL dates to the endoflife.date project and integrates both NVD and Russia’s FSTEC BDU vulnerability databases. Special handling was added for MySQL/MariaDB connection-error counters, version-string masquerading, and vendor-specific update nomenclature to avoid false reports.

Binance Confirms Record $6.3 Billion Crypto Theft via Compromised Hot Wallet and EIP-7702
Binance reported on October 30, 2026 that attackers stole approximately 6.3 billion dollars in cryptocurrency, equivalent to roughly 34 billion reais, marking the largest theft in the sector. The unauthorized transfers occurred on October 29 and were completed in about 20 minutes after the attacker compromised the system authorizing withdrawals. According to TRM Labs, the intruder leveraged Ethereum's EIP-7702 feature to seize control of a hot wallet following at least 36 hours of preparation. Initial reports pointed to a compromised DevOps engineer's laptop as the entry point, but the exchange later stated the incident involved multiple factors and was not a single-click action. Roughly 3 billion dollars have been traced, with Tether freezing over 1.57 billion USDT and Circle blocking more than 800 million USDC. Binance has committed to covering all losses through its SAFU fund and internal capital while cooperating with the FBI and U.S. Secret Service. Attribution remains disputed, with TRM Labs and Chainalysis linking the operation to the TraderTraitor group connected to Lazarus, though Binance has not confirmed the perpetrators.

SOC Forum 2026: Experts Warn Generative AI Lowers Attacker Skill Barriers While Raising SOC Complexity
At SOC Forum 2026 in Moscow, cybersecurity leaders examined how generative AI reduces the expertise needed for cyberattacks while complicating defensive operations. BI.ZONE's Oleg Skulkin noted that AI has effectively lowered attacker preparation requirements to near zero. Kaspersky researcher Georgy Kucher warned that unverified AI-generated code can expose threat actors, and overly perfect Russian-language phishing text now triggers suspicion. Solar Group’s Alexander Shepilov advocated treating AI agents as distinct non-human identities with strictly limited privileges. Alexander Kuznetsov from the same company recommended gradual automation of SOC tasks rather than abrupt AI integration. Participants also cautioned that managing AI agents may increase spending on skilled personnel instead of delivering cost savings.

Reviving Huawei SANEX9510: Expired Certificates, Zero-Byte Keystore and Lost '@' Symbol Fixed Without Database Restart
A three-day postmortem revealed seven independent failures across four TLS contours in a legacy Huawei SANEX9510 telecom OSS platform that had been offline for ten months. The issues included expired certificates, an empty 0-byte PKCS#12 keystore, a missing '@' character in an encrypted TrustStore password, incompatible PKCS#8 private key encryption formats, and connection leaks to Sybase IQ. All components were restored without rebooting servers, restarting the database, or resetting passwords. The engineer mapped every keystore reference across multiple property files to avoid breaking working segments while fixing others. A final table creation for missing DAS_DIRSIZE metadata resolved a month-old import failure unrelated to the certificate problems.

Russian Federal Tax Service Tests Scoring Model to Uncover Concealed Self-Employed Income
The Russian Federal Tax Service is piloting a new scoring system designed to detect self-employed individuals who attempt to hide revenue by improperly canceling receipts in the Moy Nalog application. The model analyzes patterns such as systematic cancellations over specific periods and instances where checks are annulled by partner platforms or banks. Vladimir Maltsev, head of the operational control department at the Federal Tax Service, confirmed that the system is already being tested in several regions. Over the first nine months of 2026, authorities imposed penalties on approximately 3,000 self-employed taxpayers for unlawful receipt cancellations, resulting in fines totaling around 300 million rubles. The approach mirrors risk-assessment techniques long used by banks and focuses not only on incoming funds but also on how users manage recorded transactions. Full details of the scoring parameters and their weighting remain undisclosed to prevent circumvention.
Anthropic's Research Claude Model Generates Exploit Bypassing Linux Protections for Root RCE via MPTCP and CVE-2026-98432
Anthropic's internal research model of Claude autonomously wrote an exploit that achieved remote command execution with root privileges on a Linux server configured with multipath TCP (MPTCP). The exploit targets CVE-2026-98432, a use-after-free vulnerability in the Linux kernel's networking stack that occurs during parallel TCP request processing. The attack first bypassed KASLR in 48 minutes to locate the required kernel address, then took an additional five minutes to seize control and execute commands as root without any password or user interaction. Anthropic disclosed the results in a technical report but noted that the experiment used an unreleased model and cannot be reliably reproduced with public chat interfaces. The Linux team rated the flaw 9.8 on CVSS while Red Hat assigned it 5.9, citing exploitation complexity; a patch has already been merged into mainline and stable branches, though users must verify updates from their distribution vendor.
Liferay Community Edition Misconfiguration Exposes Plaintext Passwords in Government Systems via CWE-319
A detailed analysis reveals how the use of Liferay Community Edition in a closed government information system led to the transmission of user passwords in plaintext through transactional emails. The issue stemmed from default notification templates that included the [$PASSWORD$] macro, combined with unadjusted system variables pointing to localhost instead of the production domain. Despite proper OAuth 2.0 delegation and CSRF protections, the misconfigured password change workflow sent permanent credentials in clear text to user inboxes. The root cause was traced to custom portlets that incorrectly reused the New Password Notification trigger intended only for administrator-initiated resets. Remediation involves removing the password macro from email templates and updating portal-ext.properties to enforce production host settings. The case highlights how open-source enterprise platforms require thorough hardening beyond initial code audits when deployed in high-security environments.
EIP-7702 Explained: How Ethereum's New Signature Standard Enables Persistent Wallet Delegation Attacks
EIP-7702, activated in May 2025 as part of the Pectra upgrade, allows Externally Owned Accounts to delegate execution to smart contract code while retaining their original address and private key. The mechanism introduces powerful features such as batch operations, gas sponsorship, and limited permissions, but also creates new attack surfaces when users sign malicious delegations. Attackers exploit social engineering to obtain EIP-7702 authorizations that install sweeper contracts capable of draining ETH, ERC-20 tokens, and NFTs without further signatures. Unlike ERC-20 approvals, the delegation persists on-chain until explicitly revoked and can affect future incoming funds across multiple networks when chain_id is set to zero. Research from 2026 identified over 900 malicious delegated accounts linked to more than $2.3 million in confirmed losses. The standard itself is not inherently vulnerable; risk stems from unsafe contract implementations and user errors when signing authorizations. Users are advised to verify delegations via Etherscan or eth_getCode and revoke them through trusted wallet interfaces when necessary.
Binance Ethereum Hot Wallets Drained of Over $5.5 Billion via EIP-7702 Delegation Attack
On October 29, attackers drained between $2.5 and $3.5 billion in ETH and tokens from Binance hot wallets on Ethereum within 40 minutes, with the total including Bitcoin and Tron reaching at least $5.57 billion according to Decrypt. The attacker did not steal private keys directly but instead used EIP-7702 to delegate execution code from a malicious contract to Binance 14, allowing a single sweep call to transfer all assets. Tether and Circle froze roughly $2.5 billion in USDT and USDC within the first hours, while Binance stated user funds remain secure and investigations continue. Blockchain analysis reveals 18 hours of preparation including three test runs on external wallets funded via Tornado Cash, followed by the main delegation and sweep in just over three minutes. The attack shares strong operational similarities with previous incidents attributed to TraderTraitor, a Lazarus subgroup, including gas funding patterns, test sweeps, and the use of a sweep function. ETH was moved first to an address that has not yet dispersed funds, while stablecoins were fragmented across new wallets before partial freezes took effect.
Russian Minister Proposes Blocking All SIM Cards of Scammers Banned in MAX Messenger
The head of Russia's Ministry of Digital Development has suggested expanding account bans in the MAX messenger to include full disconnection of all mobile numbers belonging to the same owner. Maksut Shadaev stated that simply restricting the messenger account is insufficient and that operators must continue countermeasures. The proposal also includes a cooling-off period preventing the individual from registering new numbers after a ban. Details on the duration of restrictions, data transfer procedures to operators, and appeal mechanisms remain undisclosed. Questions around accurate owner identification and cases of compromised or misused numbers are highlighted as critical for implementation. The measures target fraudsters specifically and would not apply automatically to every MAX rule violation.

China-Linked WARP PANDA Exploits VMware ESX Zero-Day CVE-2026-41709 to Evade Logging
CrowdStrike reported on 28 October 2026 that the China-linked group WARP PANDA used CVE-2026-41709, a zero-day in VMware ESX, to operate without leaving records on compromised hypervisors. The vulnerability carries a low CVSS 3.1 score of 2.7 and was added the same day to the CISA Known Exploited Vulnerabilities catalog with a remediation deadline of 11 November. Broadcom describes the flaw as insufficient logging that allows a malicious administrator to execute certain operations without them appearing in logs. The issue does not enable remote code execution or privilege escalation on its own; its value lies in erasing the audit trail that incident responders rely on to reconstruct activity. CrowdStrike linked the exploitation to espionage operations against U.S. legal-sector organizations, with activity intensifying in early 2026. The report also highlights deployment of BRICKSTORM and SharpStorm malware in vCenter environments along with stolen cloud session tokens. Broadcom has released fixed builds for ESXi 9.1, 9.0.2 and 8.0 U3j, while VMware Cloud Foundation 5 requires version 5.2.4.
Telegram Voice Call Flaw Allows Remote Code Execution on Android Devices
Security researchers disclosed a vulnerability in Telegram for Android that enables remote code execution on a victim's device simply by answering a voice call. The attacker requires only a standard account, and the flaw was present in versions 8.6.2 through 12.10.3 released between March 2022 and September 2026. Telegram addressed the issue in version 12.10.4, released at the end of September 2026. The root cause lies in improper handling of the MediaState message exchanged during calls, specifically when processing rotation values and missing video state fields, leading to out-of-bounds memory reads. The same underlying fix was deployed earlier to shared call libraries, iOS, and desktop clients, but reached Android later. Researchers confirmed the impact only on private calls running on ARM64 Android devices, with no evidence of exploitation in the wild or public CVE assignment as of October 29, 2026.
PHP2Shell Campaign Chains PHP and Linux Kernel Flaws to Compromise 25 Servers Including US Government-Linked Network

The attackers targeted 24 perimeter firewalls from a single unnamed vendor plus one internal management server across the United States, Japan, Taiwan, and South Korea. Three of the compromised devices belonged to an environment connected to the US government, where the intrusion led to domain controller access and Active Directory enumeration. The attack chain began with CVE-2026-109618 and CVE-2026-109619, which granted initial web server access, and escalated via CVE-2026-46300 (Fragnesia) to obtain root privileges. Dream observed extensive reconnaissance using the Chinese search engine FOFA, with indicators pointing to Chinese-language tooling and timing, though no specific threat actor was attributed.
Threat Actors Exploit Critical CVE-2026-101767 RCE Flaw in Oracle E-Business Suite
Threat intelligence firm Defused detected active exploitation attempts against CVE-2026-101767 targeting Oracle E-Business Suite honeypots on October 27, 2026. The vulnerability carries a CVSS 3.1 score of 9.8, requires no authentication, and resides in the Thin Client Framework servlet within the Application Object Library component. Oracle released a fix seven days earlier in its October 2026 Critical Patch Update, covering versions 12.2.3 through 12.2.15. Successful exploitation grants SQL execution under the privileged APPS database account, enabling lateral movement to operating system commands and access to financial, payroll, and procurement records. Horizon3.ai privately reported the issue in July 2026, and prior similar flaws in the same product were leveraged by the Cl0p ransomware group. Immediate mitigation includes applying the quarterly patch or restricting access to the GanttDataServer servlet via URL firewall rules.
South Korean Hacker Uses Generative AI Framework ARTEX to Breach 90 Organizations and Steal 8.2 Million Records
Seoul Metropolitan Police arrested a 32-year-old man identified only as A for conducting a series of intrusions against approximately 90 South Korean companies and institutions between September 2025 and October 2026. The attacker, who had no formal technology education and learned hacking from publicly available online materials, previously worked in penetration testing at a security firm from 2019 to 2022. Roughly 60 of the victims were compromised using the generative AI-powered pentesting framework ARTEX, which autonomously determined attack paths after receiving only the target name. The operation resulted in the theft of 8.2 million personal records and internal documents, after which the perpetrator extorted 38 organizations for a total of 360 million won in Tether, ultimately receiving 300,000 won. Police recovered part of the stolen material and are investigating possible copies on the dark web, classifying the case as the country's first large-scale incident involving generative AI. Six additional suspects remain under investigation while the main perpetrator has been referred to prosecutors on charges of violating information and communications network laws and extortion.

The patches address multiple high-severity vulnerabilities affecting TLS hostname validation and the Brotli decoder, along with updates to critical dependencies including OpenSSL and Undici. Several CVEs cover bypasses in certificate hostname checks when IP addresses use full-width digits or when hosts resolve loosely to IP addresses. A particularly serious out-of-bounds write in the Brotli decoder (CVE-2026-111497) could enable remote code execution on services processing compressed responses. Additional fixes resolve keep-alive socket timing issues, DNS resolution truncation with NUL characters, and entropy caching problems in crypto.randomUUID and randomInt functions. The releases also update c-ares, Undici, OpenSSL, SQLite and ca-cert bundles following the eMudhra intermediate CA compromise.
Node.js Fixes High-Severity Brotli Decoder Flaw Leading to Remote Code Execution
A high-severity vulnerability in the bundled Brotli decoder of Node.js allows out-of-bounds writes when processing attacker-controlled compressed data, potentially resulting in remote code execution. The flaw, tracked as CVE-2026-111497, affects all supported branches including 22.x, 24.x, and 26.x prior to the October 21, 2026 security release. Patched versions 22.23.4, 24.22.1, and 26.12.1 address the memory corruption issue that arises during Brotli decompression in services accepting third-party content. The same update resolves additional high-severity problems, notably hostname validation weaknesses in TLS. Organizations using unsupported branches such as 18.x, 20.x, 23.x, and 25.x must migrate to maintained releases, while those linking against system Brotli libraries should verify inclusion of upstream commit 0ed4268. Security teams are advised to audit all environments, including containers and CI pipelines, that process Brotli-encoded data.
PHP Issues Emergency Patches for Critical PHP2Shell RCE Flaws as Exploit Attempts Emerge
PHP has released urgent patches for two critical vulnerabilities collectively known as PHP2Shell that enable unauthenticated remote code execution on affected servers. The flaws, tracked as CVE-2026-109618 and CVE-2026-109619, score 9.2 on CVSS v4.0 and have already seen active exploitation attempts with malicious payloads adjusted to bypass WAF rules. The issues affect multiple PHP deployment methods including Apache with mod_php, PHP-FPM, php-cgi, FrankenPHP, and LiteSpeed, and do not require complex application code to be exploitable. CVE-2026-109618 involves a memory corruption chain leading to code execution under the web process privileges, while CVE-2026-109619 stems from an obsolete global state issue causing use-after-free conditions that can result in memory disclosure and code execution. Patched versions include PHP 8.5.12, 8.4.27, 8.3.36, and 8.2.35, with administrators advised to restart all persistent workers after updating. Temporary mitigations such as setting memory_limit to -1 and disabling session.upload_progress.enabled are available for environments that cannot patch immediately.
Cyberattack Exploits Exposed Danfoss Refrigeration Controllers Across French Supermarkets
A remote cyberattack targeted Danfoss AK-SM 8xxA Series controllers in French supermarkets, allowing attackers to manipulate refrigeration parameters and trigger defrost cycles that raised temperatures and spoiled food stock. The incident impacted an estimated 250 to 350 stores belonging to major chains including Intermarché, Carrefour Market, Leclerc, and others. Paris prosecutors have opened a large-scale investigation into the attack and associated damages, including potential fires. The root cause traces to outdated software on internet-exposed OT management interfaces, with multiple CVEs enabling authentication bypass and remote code execution. Thousands of similar Danfoss systems remain publicly accessible worldwide, highlighting persistent OT exposure risks. Immediate remediation steps include closing web consoles, enforcing VPN access, and applying updates to versions 4.2 and 4.3.1 or later.
Attackers Exploit Critical Atlassian Data Center Flaw CVE-2026-21589 Hours After PoC Release
Exploitation attempts against CVE-2026-21589 began almost immediately after technical details and a Nuclei template were published. The vulnerability allows unauthenticated arbitrary file read in multiple Atlassian Data Center products and carries a CVSS v4.0 score of 9.3. In environments integrated with Crowd, attackers who obtain crowd.properties can extract plaintext credentials and escalate to administrator privileges via the Crowd API. The flaw stems from improper handling of double-colon sequences in a shared web resource library, enabling path traversal against plugin resource endpoints. Affected products include Bitbucket Data Center, Confluence Data Center, Jira Software Data Center, Jira Service Management Data Center, Bamboo Data Center, Crowd Data Center, Crucible, and Fisheye. Atlassian urges immediate patching outside normal cycles and recommends WAF rules or Tomcat RewriteValve configurations to block traversal patterns. Organizations should also review access logs for double-decoded URLs containing .., /, \, or :: sequences.
LibreOffice and Apache OpenOffice Flaws Enable Remote Code Execution via Malicious Spreadsheets Without Macro Warnings
Two vulnerabilities, CVE-2026-63277 in LibreOffice Calc and CVE-2026-59265 in Apache OpenOffice, allow attackers to execute arbitrary code simply by tricking users into opening specially crafted spreadsheet files. The flaws exploit Java integration and class path handling, bypassing traditional macro security prompts entirely. LibreOffice has already released fixes in versions 26.2.5 and 26.8.0 that restrict class path entries to local file URLs only. Apache OpenOffice 4.1.16 and earlier remain vulnerable, with the stable patch expected in 4.1.17; interim mitigation requires disabling Java integration. The issues highlight risks in office suites that process untrusted documents containing external data connections or JDBC references. Organizations are advised to enforce least-privilege execution and avoid opening files from unknown sources until patches are applied.
