CISA has added two new entries to its Known Exploited Vulnerabilities catalog. CVE-2025-34291 is an origin-validation/CORS chain in Langflow, a popular open-source AI agent framework, that lets a malicious webpage exfiltrate refresh tokens and reach the code-validation endpoint for full RCE. Active exploitation began on January 23, 2026, and threat actors have been deploying the Flodric botnet through compromised instances. CVE-2026-34926 is a directory-traversal flaw in Trend Micro Apex One (On-Premise) that allows file read or write outside the intended path. FCEB agencies must remediate by June 11 per BOD 22-01; CISA urges all organisations to do the same.
Trend Micro disclosed Quasar Linux (QLNX), a previously undocumented Linux remote access trojan designed for developer workstations and DevOps environments. The malware harvests credentials for npm, PyPI, GitHub, AWS, Docker, and Kubernetes - then uses them to publish trojanized packages to public registries. QLNX runs entirely fileless and in-memory, dynamically compiling its rootkit and PAM backdoor on the target host using gcc, then loading them via /etc/ld.so.preload for system-wide interception. Capabilities include a 58-command RAT, dual-layer rootkit, keylogging, SSH lateral movement, and peer-to-peer mesh networking. Only four security tools detect the binary as malicious.
Trend Micro disclosed a China-aligned espionage cluster called SHADOW-EARTH-053 that has been targeting government and defense organizations across South, East, and Southeast Asia plus one NATO European country since at least December 2024. The group breaks in by exploiting unpatched Microsoft Exchange and IIS servers (using known flaws like ProxyLogon), drops a Godzilla web shell for persistent access, then uses DLL sideloading to load ShadowPad - a long-running Chinese implant. The targeting overlaps with Earth Alux and REF7707, suggesting either a shared operator or shared infrastructure across China-aligned groups. Targets include journalists and activists alongside government agencies.
