Skimmer Injected Into 100 Real Estate Websites via Cloud Video Platform
More than 100 real estate websites belonging to the same parent company were injected with web skimmer code via an unnamed cloud video platform.
As part of this recent campaign, Palo Alto Networks explains, skimmer code was injected into a video so that it was automatically embedded into websites that imported the video.
Leveraging this function, the threat actors provided a script that could be modified upstream, which allowed them to add the malicious content after the player was created.
“We infer that the attacker altered the static script at its hosted location by attaching skimmer code. Upon the next player update, the video platform re-ingested the compromised file and served it along with the impacted player,” Palo Alto Networks notes.
The skimmer was also designed to gather the users’ personal information, including names, phone numbers and email addresses, as well as to check the validity of the harvested data and send the information to the attackers’ command and control (C&C) server.
“The skimmer itself is highly polymorphic, elusive and continuously evolving. When combined with cloud distribution platforms, the impact of a skimmer of this type could be very large,” Palo Alto Networks says.
