Upwards of 10 million people may have visited websites carrying malicious advertisements in the last ten days, possibly infecting their computers with malware, according to computer security company Cyphort.<\/p>\n

For the past month, Cyphort has been tracking various malicious advertisement campaigns, which involve duping online advertising providers into distributing their malicious ads.<\/p>\n

If someone views a malicious advertisement, it can cause their browser to be automatically redirected to another website that attacks their computer.<\/p>\n

Nick Bilogorskiy, director of security research at Cyphort, wrote that the company has discovered over the last week a number of highly trafficked websites that are still carrying malicious ads.<\/p>\n

The malicious ads redirected people to websites that were rigged with the Angler exploit kit. An exploit kit is a software package that probes a computer for software vulnerabilities in order to deliver malware.<\/p>\n

As with previous attacks observed by Cyphort, the redirection code planted in the malicious advertisements uses SSL\/TLS (Secure Sockets Layer\/Transport Layer Security) encryption, which makes it harder for researchers to figure how users are bounced from the original webpage they were viewing to one hosting an exploit kit.<\/p>\n

The malicious ads were delivered to the website publishers by an online marketing company called E-planning. Bilogorskiy wrote that Cyphort had contacted the company, which was working to fix the problem.<\/p>\n

Online advertising agencies have been battling to keep miscreants out of their networks, but it\u2019s a hard fight. Even if an ad network scans submitted ads for malicious behavior, hackers often substitute the ads with different ones at a later time or rig the ads to pass initial security checks<\/p>\n
