Infostealer Logs Expose Replayable AI Tokens That Can Bypass MFA
Information stealer malware such as Lumma Stealer and Vidar are harvesting session tokens and API keys from compromised systems, enabling threat actors to replay these credentials and gain unauthorized access to AI services like Google Gemini, OpenAI, Anthropic, and others, bypassing multi-factor authentication. A 7 GB infostealer dump analyzed by Okta contained 44,791 unique JSON Web Tokens (JWTs), 555 of which were likely tied to AI service authentication, along with 2,937 encrypted JWE structures, primarily from OpenAI. Attackers are using stolen tokens to access premium AI models and sell access on underground forums, leveraging anti-detect browsers like Camoufox to avoid detection. The abuse of valid, unexpired API keys and tokens—termed 'LLMjacking'—allows attackers to conduct espionage, resource theft, or run up AI service bills on victims.

IT threat evolution in Q2 2026. Non-mobile statistics
In Q2 2026, multiple ransomware groups remained active, with Qilin emerging as the most prolific based on victims listed on data leak sites. Microsoft disrupted a malware-signing-as-a-service operation run by the threat actor Fox Tempest, which was used by several ransomware groups including Rhysida, Akira, and Qilin. CISA added a Windows local privilege escalation vulnerability (CVE-2026-33825, BlueHammer) to its KEV catalog due to active exploitation in ransomware attacks. Check Point attributed zero-day exploitation of a critical vulnerability in its Remote Access VPN (CVE-2026-50751) to the Qilin ransomware group. Additionally, the PayoutsKing group was observed using QEMU to deploy hidden Alpine Linux-based virtual machines as a stealthy backdoor technique.

Malicious Go Module Exposes GitHub Malware Lure Network Spanning 222 Repositories
A malicious Go module, github.com/kaleidora/dnsub-scanning-tool, serves as a lure to deliver a multi-stage Windows malware chain involving hidden PowerShell execution and encrypted payload resolution via public dead drops. The campaign, tracked as Operation Muck and Load, leverages a network of 222 GitHub repositories across 190 accounts to create credibility and scale for malicious or deceptive software projects. These repositories use synthetic activity to appear recently maintained, facilitating social engineering and malware distribution. The final payload includes RATs such as AsyncRAT, Quasar, and Remcos, along with infostealers like Vidar, enabling credential theft, screen capture, and persistence.
