4 real? Tracking exploitation and patching of eMudhra’s weak keysCloudflare's follow-up on eMudhra's eight trivially recoverable intermediate CA keys (such as 4, 56 and 66), disclosed 19 October 2026. Pingora logging showed about 22,000 handshakes with the weak keys, including about 160 forged certificates made within hours of disclosure. Probes on 50 million challenge pages show many bots, old browsers and Android WebView still trust the chain.

Jev as a judge: How counterfeit policy steers JevDatadog Security Labs tests TypeSafe AI's Jev decision model as a prompt-injection detector and as the judge behind LangChain's tool-risk gating. On four public datasets Jev had 99.66% precision and 82.90% recall. A prepended "counterfeit policy" that redefines the attack categories cut recall by over 79 points. In a LangChain scenario, a user-editable profile field lowered the mean is_risky score from 0.893 to 0.290, below the 0.5 block threshold. Plain prompt injection did not move the score.

GhostAction Returns: Malicious “Security Audit” Workflows Now Mine Credentials from Entire Git HistoriesStepSecurity details a new wave of the GhostAction campaign in which attackers used compromised maintainer accounts of Takashi Kitao (pyxel) and Henry Wu (athenadriver, Uber) to push malicious "Security Audit" GitHub Actions workflows to 345 repositories in minutes. The upgraded payload now runs `git log -p --all` to mine an entire git history (not just current secrets) for thirteen credential patterns including AWS, Anthropic, OpenAI, OpenRouter, GitHub, GitLab, Google, Slack, and SendGrid keys, pairs AWS access key IDs with secret keys via context capture, and exfiltrates everything via raw-IP plain-HTTP POST to 193.32.204.199, bypassing DNS-based defenses.

Six rounds of testing surfaced concrete defects: a false negative caused by a stripped field list, a tamper-accepted body via a service-selection parameter that let callers choose which fields were excluded from the signed message, schema-rejection and signature-failure returning byte-identical error text, and a logging/privacy gap in the operator's system that was fixed after disclosure. The author ships a companion tool, exactzk-verification-guards, which captures both a passing and an actually-reproduced failing run as regression evidence rather than a fabricated example.
