TOP ATTACKS AND BREACHES

Check Point IPS, Threat Emulation and Harmony Endpoint provide protection against this threat (Oracle Multiple Products Remote Code Execution (CVE-2025-61882, CVE-2025-61884); Ransomware.Win.Clop; Ransomware.Wins.Clop; Ransomware.Wins.Clop.ta.*)

Check Point Threat Emulation provides protection against this threat (Ransomware.Wins.Medusa)

VULNERABILITIES AND PATCHES

Check Point IPS provides protection against this threat (SmarterMail Arbitrary File Upload (CVE-2025-52691))

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 Threat Emulation and Harmony Endpoint provide protection against this threat 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. Check Point Threat Emulation and Harmony Endpoint provide protection against this threat (Ransomware.Wins.Lockbit; Ransomware.Wins.Lockbit.ta.*; Ransomware.Win.LockBit; Gen.Win.Crypter.Lockbit) Researchers uncovered PHALT#BLYX, an ongoing campaign that targets European hospitality via Booking.com-themed phishing and ClickFix-style fake BSOD/captcha lures that prompt PowerShell execution. The chain aims for credential theft and privilege elevation. Check Point Threat Emulation and Harmony Endpoint provide protection against this threat (RAT.Wins.Dcrat; RAT.Win.DCRat; InfoStealer.Wins.DcRat)
