Defend Against Online Malware
The Proofpoint global intelligence platform analyzes billions of data points a day to deliver unmatched visibility into attack patterns and methods. This fall, we saw a dramatic rise in websites compromised with SocGholish (also known as “FakeUpdates”) HTML injects.
These injections let attackers display malicious, fake browser update windows. These attacks are notable because they reflect the user’s environment: The displayed content matches the user’s browser and, in some cases, is geotargeted.
When downloaded, the script fingerprints the system and (if the user’s geolocation is targeted) executes the next-stage malware, delivering specific malware based on the presence or absence of Active Directory. Recent, highly publicized Bitpaymer infections were also associated with SocGholish activity.
Compromised Industry Sites Pose a Challenge
Threat actors have been opportunistically targeting vulnerable content management systems, including WordPress and Drupal. However, many of the compromised sites contain industry-specific content. Because website operators are unaware of the compromise, they can unwittingly subject partners and customers to the fake browser updates by inviting them to view content on their site.
Though any organization’s users could encounter compromised websites, we have seen frequent exposure to SocGholish in the following industries:
- Financial investing
