Earlier waves used trojanised installers, but this iteration contains no malware, so endpo…
F5 Labs, using Efflux sensor telemetry, reports on the most exploited CVEs of April 2025 and on internet-wide scanning for SparkRAT command-and-control servers. A single actor, using three IPs in DigitalOcean ASN 14061, sent identical HTTP POST requests to the SparkRAT in-place update endpoint, each IP scanning for about 13 hours and reac…
A Hacktron researcher argues that AI-assisted vulnerability research is rapidly widening the enterprise attack surface. He cites recent breaches at Vercel and GitHub and a wave of critical CVEs in F5, Fortinet, Cisco, Palo Alto and ImageMagick. According to the author, the Vercel compromise began with a breach of the AI platform Context.a…
Hacktron analyzes wp2shell, an unauthenticated RCE chain in WordPress core found by Searchlight Cyber.

F5 Labs assesses the security risks and rewards of Chinese open-weight LLMs (Qwen, GLM, Kimi, MiMo, MiniMax, DeepSeek). It finds that strong offensive and defensive cyber capability does not translate into consistent resistance to attack. Cited examples include Kimi K3 finding 19 vulnerabilities in Redis and GLM 5.2 being self-hosted by H…
