Threat Intelligence Red Button Security Alert: DCCBoost Attacks

Forced redirect Scareware by DCCBoost

Confiant alerts our customers whenever significant, widespread malvertising attacks occur in the digital advertising ecosystem. In this case, on March 13, 2023 the Confiant threat intelligence team notified clients of an attack by the threat actor we call DCCBoost.

Confiant's threat intelligence team has identified that threat actor DCCBoost is currently serving malicious ads through several sources.

Attack Information 

DCCBoost is currently running a forced redirect scareware campaign, targeting the US, Canada and Europe on desktop environments. DCCBoost has been using fake McAfee scareware attacks since late 2021, after a long time spent targeting mobile devices. The current campaign is especially active on DSP StackAdapt but it is also present on BuckSense. DCCBoost has had some presence on both DSPs since July 2022 and this January was very active on BuckSense via Bidswitch. The current campaign uses some additional ways to stay undetected, waiting 5 seconds before activating, and only redirecting on user interaction (scrolling, clicking, key press anywhere on the page).
