Hacker Attacks as Force Majeure: Russian and International Courts Diverge on Liability for Cyber Incidents
In November 2026, Russian hosting provider Beget suffered a major cyber attack that disrupted websites, virtual servers, email, DNS, and control panels for thousands of clients. Beget notified customers of circumstances resembling force majeure under Article 401 of the Russian Civil Code but stopped short of claiming automatic court recognition. Russian courts have reached inconsistent rulings on whether DDoS attacks and ransomware qualify as extraordinary and unavoidable events, examining factors such as attack scale, provider preparedness, and contractual obligations. International cases from France, Norway, the United States, and the Netherlands further illustrate that outcomes depend on evidence of prior security measures, backup integrity, and specific contractual language rather than the mere occurrence of an attack. Key precedents include disputes involving Timeweb, Expeditors, and Nordlo Haugesund where liability was limited or denied despite confirmed incidents. The analysis shows that even when force majeure is rejected, clients often struggle to recover full losses due to liability caps and proof requirements. Businesses are advised to maintain independent backups, review service agreements, and document incidents thoroughly to protect against financial exposure.

Taming the LLM Dragon: Corporate AI Gateway Architecture Addresses Classic Proxy Shortcomings
Spontaneous adoption of generative AI across enterprises has created shadow AI risks, prompt leaks, and uncontrolled token consumption that standard L7 proxies cannot mitigate. Traditional solutions built on Nginx, Envoy or Kong lack the ability to inspect Server-Sent Events streams, classify sensitive content inside prompts, or enforce token-based quotas in real time. The AI Optimum platform introduces a specialized AI gateway layer that sits between internal consumers and both local inference clusters and external APIs such as GigaChat and YandexGPT. It performs inline PII masking, routes traffic according to data sensitivity, supports OpenAI-compatible endpoints, and maintains detailed audit logs required under 152-FZ. The gateway adds only tens of milliseconds of latency while enabling granular billing, context caching optimization, and protection against runaway agent loops. Subsequent articles in the series will examine real corporate AI spend and further regulatory controls.

Rostelecom Refactors InfoSec Careers: Matching Employee Skills to Evolving Business Priorities
Rostelecom's information security block developed a systematic approach to reassess employee expertise and redirect talent to new roles when business structures change rapidly. In one case, an architect hired for a specific team was reassigned after the unit was disbanded, initially moving to a similar position that did not fully align with his broader competencies. HR-business partner Olga Lapshina examined the specialist's full background, including prior work in audits, methodology development, regulatory documentation, university teaching, and scientific research, plus strong mentoring abilities with younger staff. These skills matched the needs of the methodology department, leading to a transfer supported by an individual development plan and a mentor via the internal Tochka Rosta platform. Within two months the employee contributed improvements that accelerated preliminary InfoSec audits by 30 percent and risk assessments by 20 percent while expanding threat scenario coverage by 10 percent. The initiative demonstrates Rostelecom's emphasis on horizontal career movement and retention of experienced professionals through structured career tracks.

US Mandates Removal of Acronis from Federal Systems by January 2027 Over Russian Ties
US federal civilian agencies have been ordered to remove all Acronis products from their information systems by January 27, 2027, with new purchases also prohibited. The directive from the Department of Homeland Security, signed on July 31 and published in the Federal Register on October 30, covers Acronis AG along with Acronis Inc. and Acronis SCS. A nearly decade-long review examined whether Russian developers still access the code and whether supply chain risks have been sufficiently reduced, though no specific evidence of backdoors was reported by sources. After 2022, Acronis suspended operations in Russia and relocated specialists, while in 2025 Swedish firm EQT acquired a controlling stake with approval from the US CFIUS committee. Despite over 75 percent of shares now held by Western investors, these measures proved insufficient for continued access to federal systems. The ban does not extend to the private US market.

How to Avoid Becoming the Hero of 'My Program Deleted 800 GB': Safe Recursive Deletion in Bash and Python
A recent Habr article examines dangerous patterns in recursive file deletion scripts that have caused massive data loss incidents, including an 800 GB wipe triggered by Telegram Desktop on Windows. The piece analyzes classic mistakes such as empty variables in rm commands and extra spaces that turned single paths into multiple destructive arguments, referencing the 2015 Steam Linux bug and the 2011 Bumblebee installer error. It provides hardened Bash templates using set -euo pipefail, ${VAR:?} checks, realpath validation, and --one-file-system flags to prevent deletion of forbidden directories or symlinked targets. The Python section introduces a safe_rmtree wrapper that enforces root boundaries, rejects symlinks, uses resolve(strict=True), and checks shutil.rmtree.avoids_symlink_attacks before proceeding. Additional recommendations include dry-run modes, marker files, temporary directory usage, and logging to make deletion operations auditable and reversible where possible.

Backdoor with Password 123456 and Hardcoded Keys: How AI Cracked 'Encrypted' USB Drives
An AI agent rapidly discovered critical cryptographic weaknesses in multiple USB encryption and copy-protection products, including hardcoded backdoor accounts and keys that bypassed user passwords entirely. In the SecZure YutianDun drive, two hidden accounts with passwords 123456 and SECZURE.COM allowed full decryption of files without the administrator password. NetacFileLock used a fixed AES-256 key embedded in the binary, ignoring the user password completely while also logging passwords in plaintext and employing ECB mode. KakaSoft USB Copy Protection relied on a modified MD5 implementation with altered shift constants and a hardcoded internal password derived from an embedded seed, enabling full Blowfish decryption without any user input. Nexcopy stored its Triple DES content key and IV in an encrypted configuration file protected only by a fixed 32-byte certificate inside the viewer application. The AI completed analyses in minutes that previously required hours of manual time-travel debugging and reverse engineering.

CVE-2026-98432: Temporary nftables Filter with Auto-Rollback for Ubuntu Servers
Administrators are deploying a temporary nftables-based mitigation for CVE-2026-98432 on Linux systems while awaiting official kernel patches. The filter drops IPv4 TCP packets with IP header length exceeding five, reducing exposure to the vulnerability. The procedure includes verifying kernel status via Canonical, preparing rollback commands, and using systemd timers to automatically remove the table after five minutes if connectivity is lost. Steps cover syntax validation with nft --check, integration with existing firewall configurations, and post-reboot verification to ensure the temporary table persists without interfering with ufw or Docker rules. Red Hat guidance on discarding packets containing IP options is referenced as a complementary measure. The process is designed for single-server testing before scaling to production fleets, with explicit instructions to avoid flush ruleset operations that could disrupt other tables.
Old iPhones Remain Vulnerable to Bootloader Exploits Despite Airplane Mode for Crypto Seed Storage
Founder of OneKey Ishi Wang has warned that resetting an old iPhone, enabling airplane mode, and storing a cryptocurrency wallet recovery phrase on the device does not provide reliable protection. Hardware vulnerabilities such as checkm8 affecting iPhone 4S through iPhone X and usbliter8 targeting A12 and A13 chips allow attackers with physical access to bypass the secure boot chain and execute code before iOS loads. These issues persist because the bootloader code cannot be overwritten through standard resets or iOS updates. While device passcode, Secure Enclave, and application-level encryption still serve as barriers, the risk level depends on the specific model, iOS version, and password strength. Wang advises against relying on disconnected older iPhones as cold storage solutions for seed phrases.
Hackers tamper with refrigeration units in European supermarkets, setting temperatures to +50 °C
Attackers gained unauthorized access to refrigeration and freezer control systems in supermarkets across several European countries, including Sweden, Belgium, Luxembourg, and Estonia. In multiple locations they altered temperature settings to +50 °C, risking widespread spoilage of perishable goods. The incidents primarily affected older, unpatched Danfoss controllers that had been connected to networks for remote maintenance. Estonian manufacturer Kitman Coldtech reported that one attack on a legacy Danfoss system was detected and stopped within approximately ten minutes, preventing any damage. Similar intrusions were confirmed by Swedish chains ICA and Coop, following earlier incidents in French supermarkets in October that resulted in product losses. Experts note that legacy industrial controllers remain attractive targets because they are often left exposed once placed online for convenience.
Russian Li Auto Owners Face Master Account Theft and Extortion Up to 45,000 Rubles
Russian owners of Li Auto vehicles are experiencing a wave of master account compromises that allow attackers to seize control through the official mobile app. After losing access, some vehicles lose screen functionality, climate control, and in certain cases the ability to start. Attackers then contact victims demanding 35,000 to 45,000 rubles for account return. Approximately 20 confirmed cases have been reported, though the real number may be higher. The exact infection vector remains unknown, and even owners who previously used the paid eSender service to retain Chinese phone numbers are now affected. Li Auto and official distributor Sinomach Auto are developing recovery procedures and plan to migrate account binding from Chinese numbers to email addresses.
Docker Bypasses UFW Firewall Exposing PostgreSQL and Redis Ports to Rapid Malware Infections
A common Docker Compose setup with exposed database ports on fresh VPS instances allows attackers to compromise systems within minutes despite active UFW rules. Docker's use of DNAT rules in the PREROUTING chain and insertion of DOCKER-FORWARD chains before UFW rules in the FORWARD table routes external traffic directly to containers on internal bridge networks. IPv6 support in Docker versions 27 and later creates additional exposure vectors when administrators focus only on IPv4 protections or disable IPv6 filtering. Bots scan cloud IP ranges for open ports including 5432 and 6379, deploying miners such as kdevtmpfsi and kinsing or using Redis replication to load malicious modules. Historical cases include a Qdrant test instance on Hetzner compromised in under two minutes and similar issues reported in Spree Commerce starter templates. The article details Netfilter mechanics, protected-mode limitations in Redis, and specific exploitation techniques like CONFIG SET for cron jobs and CVE-2022-0543 Lua sandbox escapes.
Google to Back Unified robots.txt Standard for Blocking AI Training Data Use
Google has announced plans to support a common mechanism in robots.txt that allows website owners to opt out of having their content used for training generative AI models. The feature will be based on work by the AIPREF working group at IETF and is scheduled for rollout in 2027. Instead of issuing separate instructions to each AI provider, publishers will be able to set a single policy marker that participating companies are expected to respect. Google intends to treat an unspecified general marker the same way it currently handles its own Google-Extended directive. Existing per-company rules will continue to function, letting site owners combine a broad default with specific exceptions. The approach simplifies management as the number of AI crawlers grows, though compliance will remain voluntary and dependent on which organizations adopt the standard.

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.
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
Israeli security firm Dream disclosed a sophisticated campaign that achieved root access on 25 servers by chaining two remote code execution vulnerabilities in PHP2Shell with a Linux kernel flaw. 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.

Node.js Issues Security Releases for 26.x, 24.x and 22.x Fixing High-Severity TLS and Brotli Flaws
Node.js published security updates on October 21, 2026 for the 26.x, 24.x and 22.x release lines. 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.

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.
