Security experts recommend implementing robust web filtering solutions, keeping browsers updated, and training users to recognize fake update notifications as critical mitigation strategies against this evolving threat. The infection begins when users visit these legitimate but compromised websites, which then display fake browser update notifications. The infection sequence begins with compromised websites containing injected JavaScript code that evaluates the visitor’s browser environment. This sophisticated attack chain involves multiple stages of deception, beginning with legitimate websites that have been infiltrated and modified to serve malicious JavaScript to unsuspecting visitors. The cybersecurity landscape has witnessed a concerning development as threat actors behind SocGholish have begun weaponizing compromised websites to distribute the dangerous RansomHub ransomware. Investigation of the compromised websites revealed injected obfuscated JavaScript code, typically inserted near the end of legitimate JavaScript files or directly into HTML content. The newly observed attack chain now culminates in the deployment of RansomHub ransomware, a relatively new but increasingly prevalent ransomware variant that implements strong encryption algorithms and sophisticated evasion techniques. The campaign uses compromised websites as initial infection vectors, creating a widespread distribution network that’s difficult to detect and mitigate. When users interact with these fake update notices, they download a ZIP file containing a malicious JavaScript file. Trend Micro Security researchers identified this evolving threat campaign targeting organizations across multiple sectors, with a particular focus on healthcare, finance, and manufacturing industries.

The ransomware payload itself utilizes sophisticated techniques including process hollowing and API unhooking to bypass security solutions. Their analysis revealed that the threat actors have enhanced their techniques to evade detection while expanding their ransomware deployment capabilities. Browser fingerprinting techniques determine if the victim uses Chrome, Firefox, or Edge before displaying the appropriate fake update notification.
