Confiant alerts our customers whenever significant, widespread malvertising attacks occur in the digital advertising ecosystem. In this case, on May 9, 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.
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 mostly active on BuckSense via many DSPs.
DCCBoost had been slowly staging a return to ad tech after a period of inactivity through the second half of 2022 with a peak during January 2023. After another spike of activity in March, they have returned via BuckSense with similar tactics and a slightly improved obfuscation (adding a layer of AES encryption to their JavaScript).
This campaign also 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).
The attack started on May 3 and has ramped up during the weekend and through Monday, May 8.
