Microsoft Teams for Android Vulnerability Exposes Sensitive Information
Microsoft patched CVE-2026-65812 in Teams for Android, an information-disclosure flaw that can leak credentials under specific conditions.
Microsoft fixed CVE-2026-65812, rated Important, which can insert sensitive information such as credentials into data sent by Microsoft Teams for Android (build 1416/1.0.0.2026133602). Exploitation is remote and low-complexity, requires low privileges plus user interaction, and impact is limited to high confidentiality impact. Microsoft says exploitation is less likely, with no public PoC, disclosure, or in-the-wild exploitation; the fix ships via the Teams app update on Google Play. Ofek Levin of Enclave reported the flaw through coordinated vulnerability disclosure.

Kimwolf v7 Hides DDoS Traffic Behind Chrome Fingerprints and Ethereum
Unit 42 details Kimwolf v7, an Android TV botnet upgrade using HTTP/2 Chrome-fingerprint DDoS floods and Ethereum ENS-based C2 across 1.8M+ infected devices.
Palo Alto Networks Unit 42 identified Kimwolf v7 on February 3, 2026, an upgrade to an Android TV botnet active since August 2025 and linked to the AISURU botnet, which has infected over 1.8 million devices. The new version adds an HTTP/2-based DDoS flood that mimics full Chrome browser fingerprints, consolidates 43 attack commands into 15 methods covering layers 3-7, and resolves C2 addresses via Ethereum Name Service using five hard-coded public blockchain RPC endpoints, backed by a Tor hidden service and a local proxy on 127.0.0.1:23075. It spreads through residential proxies to Android TV boxes with ADB enabled on port 5555 and masquerades as netd_service. The botnet is associated with the record 31.4 Tbps DDoS attack in November 2025.
