A new UEFI bootkit named BlackX, deployed in an espionage campaign in early 2026, exploited the old Baton Drop vulnerability to bypass Secure Boot and load a malicious driver designed to interfere with security solutions from Kaspersky and Avast. The operation has been attributed with medium confidence to APT41, a Chinese state-sponsored threat group also known as Brass Typhoon, Wicked Panda, and Barium. It was discovered in early 2026 and targeted diplomatic agencies in Central Asia, particularly in Tajikistan, Uzbekistan, and Turkmenistan. Kaspersky researchers analyzed the BlackX bootkit and found similarities with BlackLotus, which has been circulating on hacker forums since October 2022 and leveraged the Baton Drop vulnerability (CVE-2022-21894) to bypass Secure Boot protection. ESET confirmed in March 2023 that BlackLotus exploited Baton Drop, and at the time it could compromise even fully patched Windows 11 systems.
A memory-corruption flaw in Google's Brotli decoder sits in many programs that unpack Brotli-compressed data, among them Bun, the Python Brotli and brotlicffi packages, and Envoy proxies set up to decompress Brotli. Tracked as CVE-2026-111497, the flaw allows crafted compressed data to overwrite past the end of a buffer and corrupt a program's memory, potentially
LiteLLM on Friday revealed that an Agent Platform master key accidentally published to a public GitHub repository in late May 2026 ultimately allowed the threat actor to push a malicious version of the popular Python package. "On May 27, 2026, a configuration file was committed to the public LiteLLM-Labs/lite-harness repository which inadvertently contained the master key to a deployment of
Google has updated its privacy policy to spell out that using personalized artificial intelligence (AI) features in Search or Gemini could allow the company to serve targeted ads to users based on their activity on other connected Google services.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added two vulnerabilities impacting Collabora Online Built-in CODE Server and Arista VeloCloud Orchestrator (VCO) to its Known Exploited Vulnerabilities (KEV), citing reports of active exploitation in the wild. The critical-severity vulnerabilities are listed below - CVE-2026-110447 (CVSS score: 9.2) - An operating
Researchers remotely disabled a vulnerable updater in the abandoned Time4Popcorn app, a fork of the Popcorn Time BitTorrent client, closing a security flaw that could have allowed attackers to execute malicious code with elevated privileges on millions of computers.
Microsoft says Teams will begin using AI-powered phishing detection in early November 2026 to detect malicious behavior in messages. The rollout is part of a targeted release phase expected to end by mid-November, with the new security feature likely reaching general availability worldwide between early and mid-December. Microsoft first revealed in a Microsoft 365 Roadmap entry last week that the AI-powered phishing detection will use conversation context (without retaining message content) to identify phishing and suspicious behavior in higher-risk messaging scenarios, such as external first-contact chats. "Microsoft Teams is introducing AI-powered, context-aware phishing detection to help identify phishing, social engineering, impersonation attempts, and deceptive intent," the company said in a Microsoft 365 Message Center update on Wednesday.
Diplomatic organizations in Central Asia have been targeted by a sophisticated new Unified Extensible Firmware Interface (UEFI) bootkit called BlackX. The activity, which singled out diplomatic entities in Tajikistan, Uzbekistan, and Turkmenistan in early 2026, is suspected to be orchestrated by a China-linked state-sponsored hacking group known as APT41, Kaspersky said in a technical report
Ruby has released versions 4.0.9, 3.4.12, and 3.3.13 to fix three bugs in Onigmo, the regular expression engine built into the language. The bugs lie behind four critical security flaws that GitLab patched over the past month. GitLab found that a specially crafted pattern could corrupt memory while Ruby compiles it, potentially leading to code execution on its own servers. Ruby says any
Microsoft says Windows Server 2016 will stop receiving security updates after it reaches the end of support in January 2027.
