Trustwave SpiderLabs: SYS01 and Rilide Linked to Same Actor
Drawing on extensive proprietary research, Trustwave SpiderLabs believes the threat actors behind the Facebook malvertising infostealer SYS01 are the same group that developed the previously reported Rilide malware. Facebook Malvertising Epidemic – Unraveling a Persistent Threat: SYS01 – Part 2 lays out evidence tying the latest Rilide (V4) version to SYS01. The report noted the code from the two malware types overlaps in too many areas to be a simple coincidence.
