Malicious advertisements, some of which were displayed on YouTube, redirected more than 113,000 people in the U.S. to harmful websites in just a month, Trend Micro said Tuesday.<\/p>\n

Although online advertising companies try to detect and block such ads from being circulated on their networks, bad ones sometimes get through. Such ads can be very productive for hackers. It can mean a large pool of victims if shown on a high-traffic website.<\/p>\n

\u201cThis was a worrying development: Not only were malicious ads showing up on YouTube, they were on videos with more than 11 million views\u2014in particular, a music video uploaded by a high-profile record label,\u201d wrote Joseph Chen, a fraud researcher, on Trend Micro\u2019s blog.<\/p>\n

Google, which owns YouTube, did not have an immediate comment.<\/p>\n

Chen wrote that users viewing the ads were bounced through two servers in the Netherlands before landing on the malicious server, which is located in the U.S.<\/p>\n

That server had the Sweet Orange exploit kit installed. Sweet Orange checks if the computer has one of four vulnerabilities affecting Internet Explorer, Java or Adobe Systems\u2019 Flash application.<\/p>\n

If the attack is successful, the kit delivers malware from the KOVTER family, which has been used in the past for ransomware, Chen wrote. Those attacks try to extort a victim by either encrypting their files or tricking them into paying a fine.<\/p>\n

The KOVTER malware is hosted on a subdomain of a Polish government site that has been hacked, Chen wrote. The attackers had also modified DNS (Domain Name System) information on that site by adding subdomains that led to their own servers, but the method used to accomplish that was unclear, Chen wrote.<\/p>\n
