Threat Actors Are Posing as OpenAI, Anthropic and DeepSeek to Target Credentials and Secrets
GreyNoise observes scanners spoofing OpenAI, Anthropic, and DeepSeek crawler user agents to hunt leaked credentials and secrets.
GreyNoise is observing automated scanners that pose as the web crawlers of OpenAI, Anthropic, DeepSeek, and Fortune 500 companies.

U.S. CISA adds a Ray-Project Ray flaw to its Known Exploited Vulnerabilities catalog
CISA added actively exploited Ray RCE flaw CVE-2025-62593 (CVSS 9.4) to its KEV catalog, ordering federal agencies to patch by August 20, 2026.
CISA added CVE-2025-62593 (CVSS 9.4), a critical remote code execution flaw in the Ray AI compute engine, to its Known Exploited Vulnerabilities catalog with a due date of August 20, 2026. Versions before 2.52.0 relied on a User-Agent header check to guard the dashboard/API, which combined with DNS rebinding allows arbitrary code execution on developers' machines via malicious websites or ads. Aviatrix's analysis describes privilege escalation, lateral movement, command and control, and data exfiltration following exploitation. Federal civilian agencies must remediate under BOD 22-01; the flaw affects Firefox and Safari.
