More than 100 real estate websites belonging to the same parent company were injected with web skimmer code via an unnamed cloud video platform.
Increasingly popular, skimmer attacks involve the use of malicious JavaScript code to steal data provided by users on the targeted website.
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.
The attack was possible because the abused cloud video platform allows users to add their own JavaScript customizations to players, by uploading a JavaScript file that is included in the player.
