ClickFix Phishing Campaign Targets Hotels, Delivers PureRAT

🔒 Sekoia warns of a large-scale phishing campaign targeting hotel staff that uses ClickFix-style pages to harvest credentials and deliver PureRAT. Attackers impersonate Booking.com in spear-phishing emails, redirect victims through a scripted chain to a fake reCAPTCHA page, and coerce them into running a PowerShell command that downloads a ZIP containing a DLL-side‑loaded backdoor. The modular RAT supports remote access, keylogging, webcam capture and data exfiltration and persists via a Run registry key.

Phishing texts impersonate Find My to steal Apple IDs

📱 The Swiss NCSC warns of smishing attacks that impersonate Apple's Find My team, telling owners their lost iPhone has been found to lure them to a fake login page. Messages can cite device details visible on the lock screen and use the displayed contact info to target victims. The counterfeit pages request the user's Apple ID and password, which attackers then use to remove Activation Lock. Users should enable Lost Mode, avoid unsolicited links, use a dedicated contact email, and protect their SIM with a PIN.

Cybercriminals Increasingly Target Online Payroll Systems

🔒 Microsoft warns of an emerging scam targeting online payroll systems, in which attackers use social engineering to steal employee and administrator credentials. Those credentials are abused to reroute direct deposits into attacker-controlled accounts, and fraudsters may take extra steps such as changing contact details or suppressing notifications to delay detection. The advisory highlights how moving payroll online creates new avenues for account takeover and financial fraud, and urges employers and vendors to strengthen authentication, monitoring, and verification processes.

Critical Auth Bypass in JobMonster WordPress Theme Attack

🔒 Threat actors are actively exploiting a critical authentication bypass in the JobMonster WordPress theme (CVE-2025-5397) that can lead to administrator account takeover under specific conditions. The flaw affects all versions up to 4.8.1 and is caused by the theme's check_login() function trusting external social login data without proper verification. To succeed, attackers typically need social login enabled and knowledge of an admin username or email. The issue is fixed in 4.8.2; immediate mitigations include upgrading, disabling social login, enabling two‑factor authentication, rotating credentials, and reviewing access logs.

Russian Police Arrest Suspected Meduza Stealer Operators

🔒 Russian authorities have arrested three individuals in Moscow accused of creating and operating the Meduza information‑stealing malware. Announced on Telegram by police general Irina Volk, investigators say the group developed and distributed Meduza via hacker forums around two years ago and offered it as a subscription-based service. The tool steals browser-stored credentials and cryptocurrency data and, since December 2023, can resurrect expired Chrome authentication cookies to facilitate account takeover. Authorities opened a criminal case after operators targeted an Astrakhan institution and seized confidential server data.

Stolen Credentials and Remote Access Abuse in 2025

🔒 FortiGuard Incident Response observed that in H1 2025 financially motivated actors frequently used stolen credentials and legitimate remote-access software to gain and extend access across environments. Adversaries relied on compromised VPN logins, password reuse, or purchased credentials, deploying tools like AnyDesk, Splashtop, Atera and ScreenConnect to move laterally and exfiltrate data manually. These intrusions often bypass endpoint-focused defenses because activity mimics normal user behavior, so FortiGuard emphasizes identity- and behavior-driven detection, broad MFA enforcement, and monitoring of remote access tooling.

Atlas browser CSRF flaw lets attackers poison ChatGPT memory

⚠️ Researchers at LayerX disclosed a vulnerability in ChatGPT Atlas that can let attackers inject hidden instructions into a user's memory via a CSRF vector, contaminating stored context and persisting across sessions and devices. The exploit works by tricking an authenticated user to visit a malicious page which issues a CSRF request to silently write memory entries that later influence assistant responses. Detection requires behavioral hunting—correlating browser logs, exported chats and timestamped memory changes—since there are no file-based indicators. Administrators are advised to limit Atlas in enterprise pilots, export and review chat histories, and treat affected accounts as compromised until memory is cleared and credentials rotated.
