New Mobile Malware Taps Ad Networks To Spread

It was only a couple weeks back that we wrote about new research from the folks at WhiteHat Security that posited a way for mobile ad networks to be gamed and used to distribute malicious code. Now it looks as if the bad guys were one step ahead, as researchers at Palo Alto Networks reveal new type of malicious Android malware that uses mobile ad networks to infect vulnerable devices. Palo Alto described the new, malicious mobile software, dubbed “Dplug,” in a blog post on Monday. The company said the malware authors appear to be leveraging second tier mobile ad networks, mostly in Russia and the former Soviet Republics), to distribute their wares. The Dplug malware takes advantage of the deep integration between mobile applications and mobile advertising networks to gain a foothold on infected devices, then send out messages to premium SMS services to generate money for the fraudsters, according […]

Even if the language in their message is generic enough to avoid detection, dropping a link to a known, malicious- or compromised domain is plenty to get an entire message dropped.

Lately, a method that’s drawing attention is to leverage low-security redirection services to whitewash a link to a ‘known-malicious’ or merely suspicious sites. Barracuda Networks said that it has captured spam attacks that are combining a Yahoo based URL shortening service with Google’s free Translate service to whitewash links in spam e-mail messages and evade automated detection. The message, which was sent to a Barracuda “honeypot” system  includes a […]

According to a report in South Korea’s Yonhap News Agency, the attacks began at 2:00PM local time in South Korea and affected the computer networks of three broadcasters and two banks. Broadcasters KBS, MBC and YTN all reported that their computer networks were “halted” at that time. Shinhan Bank and Nonghyup made similar reports to the National Police Agency (NPA), according to Yonhap. Unlike past distributed denial of service (DDoS) attacks that are believed to have been launched by the DPRK against the South, the latest incursions come at a time of extreme military tension on the peninsula, and caused damages to South Korean […]
