- SmarterTools fixed CVE-2025-52691, a critical pre-auth remote code execution flaw with a CVSS score of 10.0. Successful exploitation allows an attacker to upload files and write to web-accessible paths, potentially resulting in full server compromise.
Check Point IPS provides protection against this threat (SmarterMail Arbitrary File Upload (CVE-2025-52691))
- A patch was released for CVE-2025-64496 vulnerability in Open WebUI, a self-hosted interface for AI models, enabling code injection via the Direct Connection feature and potential remote code execution. Versions through 0.6.34 are affected.
- Cisco has addressed CVE-2026-20029, a medium-severity flaw in Identity Services Engine and ISE-PIC, which allows administrators to access sensitive files via improper XML parsing. Exploitation of the flaw requires valid admin credentials.
THREAT INTELLIGENCE REPORTS
- Check Point Research observed GoBruteforcer, a modular Go botnet brute-forcing Linux servers running phpMyAdmin, MySQL, PostgreSQL and FTP. Campaigns exploit AI-generated server deployments that propagate common usernames and weak defaults. The botnet converts hosts into scanners and credential harvesters, with crypto-focused runs stealing funds and expanding access through backdoors and IRC-based control.

- Check Point researchers identified the OPCOPRO “Truman Show” investment scam, which industrializes social engineering via WhatsApp and Telegram. Apps from official stores serve as interfaces to attacker servers, fabricating balances and trades, harvesting KYC documents, and driving identity theft and deposits.
Check Point Harmony Endpoint provides protection against this threat
- Researchers analyzed LockBit 5.0 ransomware, detailing ChaCha20-Poly1305 file encryption, X25519 with BLAKE2b key exchange, termination of VSS and backup services, and Temp directory cleanup. LockBit 5.0 uses custom random extensions per execution, excludes system files, supports Stealbit exfiltration, and drops a ransom note threatening data leakage.
