Evento MISP pubblicato con TLP:CLEAR: Securonix Threat Research Security Advisory: Analysis of Ongoing FROZEN#SHADOW Attack Campaign Leveraging SSLoad Malware and RMM Software for Domain Takeover. Report from - [URL rimossa] (1714055659) ## tldr: The Securonix Threat Research team (STR) observed an interesting attack campaign which leveraged SSLoad malware and Cobalt Strike implants resulting in the attackers being able to pivot and take over the entire network domain. SSLoad malware was the primary vector deployed by threat actors during the FROZEN#SHADOW campaign along with Cobalt Strike and ScreenConnect RMM (remote monitoring and management) software. SSLoad is designed to stealthily infiltrate systems, gather sensitive information and transmit its findings back to its operators. Once inside the system, SSLoad deploys multiple backdoors and payloads to maintain persistence and avoid detection. Not to be confused with SLoader which gained traction between 2018 and 2020, SSLoader is relatively new to the malware scene. The malware is typically introduced into the system through phishing email campaigns. Based on gathered telemetry, victimology appears to be completely random, affecting targets in Asia, Europe and the Americas. The phishing emails contain a single link which redirects from a mmtixmm[.]org URL to a single JavaScript file which is downloaded onto the victim machine. Manually executing the single JavaScript file kicks off the code execution chain downloading and executing further stages. After the initial infection, the Threat Research team was able to obs
