New RomCom Variant Spotted: A Comparative and Expansion Analysis of IoCs

RomCom has once again evolved and been made stealthier as per its latest variant, Snipbot.

The new version was popularly used in attacks that led to data theft, while the previous variants were used to deliver ransomware. The victim pool included organizations across various sectors, including legal and IT services.¹

The WXA research team sought to compare the list of IoCs of the three latest versions—RomCom 3.0,² RomCom 4.0,³ and Snipbot.⁴ We also expanded the list of IoCs to uncover more potentially connected artifacts. Using WHOIS, IP, and DNS intelligence, our analysis led to the discovery of:

• 20 email-connected domains, some were found to be malicious
• 27 additional IP addresses, all of which were found to be malicious
• 122 IP-connected domains, some were found to be malicious
