Last week, we talked about a fake Android rooting tool, a supposedly unlimited offer of games that eventually ended in frustration, and an adware that does it very best to stay undetected. One of our experts also offered their insight regarding a book entitled “Dot Con” and how conning the con man can lead to more trouble and less fun.

Thomas Reed, the Labs’s Mac security expert, documented a newer variant of the adware installer that is taking advantage of the DYLD_PRINT_TO_FILE vulnerability in OS X, which we disclosed in early August. Although this latest adware is essentially similar to the one found before, it also installs a Genieo Safari extension by mounting a disk image and automatically allowing it access to the keychain. A number of reports have dubbed this the “BrokenChain vulnerability”.

Senior security researcher Jérôme Segura once again found a malvertising campaign, this time, targeting the online dating site, Match.Com. He added that this is similar to the PlentyOfFish campaign he spotted and wrote about not long ago. This campaign uses the Angler exploit kit to serve affected users with other malware.

Lastly, Chris Boyd, one of our malware intelligence analysts, documented a new Skype spam campaign that carries a Baidu link that was used to hide the location of it’s true destination. In this case, a fake weight loss or diet news page.
