Threats Tagged 'c2 framework'

A recent attack on a poorly managed MS-SQL server involved the use of XiebroC2, an open-source C2 framework similar to CobaltStrike. The attackers exploited vulnerable credentials, installed JuicyPotato for privilege escalation, and then deployed XiebroC2 using PowerShell. XiebroC2 supports various features including remote control, information collection, and defense evasion across multiple platforms. The malware collects system information and connects to a C&C server for command execution. To protect against such attacks, administrators are advised to use complex passwords, regularly update them, keep security software current, and implement firewalls to restrict external access to publicly accessible database servers.

AdaptixC2, an open-source post-exploitation and adversarial emulation framework, has been observed being used in real-world attacks. This versatile tool allows threat actors to execute commands, transfer files, and perform data exfiltration on compromised systems. Its open-source nature enables easy customization, making it highly flexible and dangerous. The framework supports sophisticated tunneling capabilities, modular design with extenders, and various beacon agent formats. Two infection scenarios were analyzed: one using social engineering via Microsoft Teams, and another likely involving AI-generated scripts. The increasing prevalence of AdaptixC2 in attacks, including its use alongside ransomware, highlights the growing trend of attackers leveraging customizable frameworks to evade detection.
