2nd November – Threat Intelligence Report

For the latest discoveries in cyber research for the week of 2nd November, please download our Threat Intelligence Bulletin.

TOP ATTACKS AND BREACHES

Binance, a global cryptocurrency exchange, has suffered a cyberattack resulting in the theft of approximately $6.3 billion in digital assets. Attackers reportedly compromised a DevOps engineer’s laptop and abused internal wallet infrastructure to authorize unauthorized withdrawals. The incident ranks among the largest cryptocurrency thefts ever recorded and is linked to North Korean group.
Polymarket, a US-based prediction market platform, has disclosed a cyberattack involving a compromised third-party service that distributed malicious JavaScript to its website. The script hijacked authenticated trading sessions and attempted unauthorized transactions. Approximately $2.7 million in cryptocurrency was traced to a suspected attacker-controlled wallet.
Japan Airlines, a major Japanese international airline, has disclosed a third-party data breach affecting approximately 92,000 passengers through the Amadeus reservation system. Exposed records included passenger names and flight information. Approximately 2,000 individuals also had contact information, passport details, and additional travel records potentially accessed.
The Florida Department of Education has disclosed a data breach involving unauthorized access to its student financial aid website, potentially affecting 4.9 million individuals. Compromised information reportedly includes names, Social Security numbers, dates of birth, addresses, and contact details. The incident was identified on October 19.

AI THREATS

Researchers have identified extensive use of AI agents by the GOLD OGRE ransomware group during Aur0ra attacks. Operators supplied compromised credentials and objectives, allowing AI tools to perform network reconnaissance, identify privileged accounts, and support lateral movement. The group also used AI-assisted development to test endpoint security evasion techniques.
Researchers have documented expanding AI adoption among North Korean cyber threat actors. The activity includes using language models to support reconnaissance, develop malicious tools, refine social engineering, and accelerate intrusion workflows. The findings describe how established espionage and financially motivated operations are incorporating AI into existing attack techniques.
Researchers have uncovered a global espionage campaign in which the China-linked VAPOR PANDA group used the AI-enabled ARTEX framework against more than 200 organizations. Targets included government agencies, telecommunications providers, and defense companies across at least 14 countries. Confirmed intrusions involved credential theft and deployment of the BLOODALCHEMY backdoor.

VULNERABILITIES AND PATCHES

Check Point Research have analyzed HTTP2Shell (CVE-2026-111497), an actively exploited remote code execution vulnerability affecting Brotli decompression implementations. Initially associated with Node.js, the flaw may also affect other components, including Python packages, .NET, and proxies. Automated scanning and suspicious exploitation attempts have been observed.
Check Point IPS provides protection against this threat (Node.js Brotli Remote Code Execution (CVE-2026-111497)))
A critical Linux kernel vulnerability, CVE-2026-98432, has been disclosed with a CVSS score of 9.8. The memory management flaw affects TCP networking and can enable unauthenticated remote code execution with root privileges on systems exposing Multipath TCP listeners.
Drupal has addressed CVE-2026-118539, a highly critical access control vulnerability in the Commerce Core module used by online stores. Insufficient protection of application routes and data fields allows unauthenticated attackers to bypass authorization restrictions. The flaw has been exploited in attacks and may affect commercial transactions.
Cisco has patched CVE-2026-76418, a high-severity vulnerability affecting Adaptive Security Appliance and Firepower Threat Defense software. The flaw allows unauthenticated attackers to remotely crash devices configured with SSL VPN functionality. Cisco confirmed that the vulnerability had been exploited in attacks before the security updates became available.

THREAT INTELLIGENCE REPORTS

Check Point Research has uncovered the Yoba malware campaign, which distributes malicious installers disguised as ChatGPT and Claude desktop applications through fraudulent GitHub projects. Attackers exploit legitimate signed executables to load malicious components and establish persistence. The campaign uses trusted online services for payload delivery and communication.
Check Point researchers has analyzed unexpected network activity generated by Alibaba’s Qwen model during a security-related task. Repeated testing produced numerous different destination addresses rather than one consistent endpoint. The findings suggest unstable model behavior is a more plausible explanation than a deliberately embedded data-exfiltration mechanism.
Researchers have identified UAT-11473, an advanced threat actor exploiting a Cisco Catalyst SD-WAN authentication bypass to deploy the KeyDrift malware framework. The campaign targeted organizations in aerospace, defense, satellites and policy research. KeyDrift enables persistent access and extraction of sensitive encryption material from compromised network controllers.
Researchers have documented more than 400 incidents involving abuse of Microsoft Teams external chat functionality for initial access. Attackers impersonated internal IT support personnel to persuade employees to initiate remote sessions and install access tools. Some campaigns progressed to credential theft, lateral movement, and ransomware-related activity.
