Threat actors are conducting a multi-wave campaign using social engineering lures themed around Zoom updates, business documents, and system utilities to deploy ScreenConnect Remote Monitoring and Management agents. The operation employs VBScript droppers, batch loaders, compiled .NET executables, and HTML phishing pages, all retrieving payloads from a WsgiDAV staging server at 207.174.0.143:8080. Victims receive silently installed ScreenConnect agents that beacon to three attacker-controlled relay servers, providing persistent remote access. The campaign demonstrates technical evolution from obfuscated VBScript with XOR encryption to aggressive .NET loaders executing nine-step Windows Defender destruction sequences. Cross-platform variants target both Windows and macOS systems. All payloads are legitimately signed ConnectWise ScreenConnect MSIs, designed to evade security controls that trust code signing. The threat actor actively rotates payload hashes and recently pivoted to stealth tactics specifically...

An authentication bypass vulnerability in the Check Point SmartConsole login process allows an unauthenticated remote attacker to obtain an application login token and use it to authenticate with full administrative privileges. Successful exploitation allows the attacker to modify security policies and security configurations. Remote exploitation requires internet access to the Management Server IP address and a configuration that does not restrict Trusted Clients. Check Point is aware that this vulnerability is being exploited and has affected a very small number of customers.

Kratos is a mature Phishing-as-a-Service operation targeting Microsoft 365 users across the United States, Europe, and other regions. The platform enables attackers to steal credentials through trusted platforms, anti-bot verification, and convincing login pages. Researchers traced three generations of the kit and uncovered 1,484 previously unattributed detonations. The operation targets organizations across more than 20 countries with particularly strong concentration in the US, Spain, and Southern Europe. Kratos includes an operator panel allowing deployment of phishing domains, configurable Telegram or email delivery, geographic restrictions, and multiple anti-bot systems. The kit has evolved through three page generations (V0, V1, V2) with different exfiltration code. Activity has been visible since January 2026, with the operator panel active since September 2025.
