5 months ago admin2 Comments Off on Malware Monero Miner Targets Google’s DoubleClick
The attackers targeted Google’s DoubleClick, which provides Internet ad serving services for distribution, Trend Micro reported on its security intelligence blog. In addition, the maladvertisements also used a separate web miner that connects to a private pool.
Trend Micro has reported its findings to Google about the campaign, which affected Japan, France, Taiwan, Italy and Spain.
Trend Micro noticed a rise in traffic to five malicious domains on Jan 18, and on Jan. 24 it found a near 285% jump in the number of Coinhive miners. The traffic came from DoubleClick advertisements.
Web Miner Scripts Embedded
Two different web miner scripts were embedded, along with a script displaying the advertisements from DoubleClick. The attacked web page displayed the legitimate advertisement while the two web miners conducted their covert tasks.
The use of the advertisements on legitimate websites is believed to be a ploy to attack a greater number of users.
The traffic connected to these miners declined after Jan 24.
