Malvertising or malicious advertising is targeting major websites like YouTube, Yahoo, Amazon serving a unique piece of malware to different users, Cisco has warned.
According to the security experts, net users who have visited amazon.com, ads.yahoo.com, www.winrar.com, youtube.com, or any of the 74 domains could leave their Windows or Mac system at risk of "Kyle and Stan" Malvertising Network.
The network claimed to distribute sophisticated, mutating malware for Windows and even Macs.
The networking group that spreads the malware claims to be active since last May which banks on advertising to spread malware.
In an investigation over 700 domains has revealed the malware could have affected more than 10,000 users.
The mailware claimed to affect the system with spyware, adware, browser hijackers and uses advanced techniques for encryption to avoid detection.
Once the user visits the page of malicious advertisement they get redirected to a different website and the final page starts the downloading a malicious file containing legitimate software and media player, and once the installation is completed the system gets infected.
Security researcher Armin Pelkmann said in a blogpost: "The attackers are purely relying on social engineering techniques in order to get the user to install the software package."
"No drive-by exploits are being used thus far."
"All in all we are facing a very robust and well-engineered malware delivery network that won’t be taken down until the minds behind this are identified."
