Avira TechBlog: We discovered a new ransomware threat which is downloaded by a Trojan of the Oficla family. This downloaded threat replaces the MBR (master boot record) of the hard disk with its own MBR which asks the user for a password and thus blocks the loading of the operating system. Upon starting the Oficla Trojan and successive execution of the downloaded payload the system will be rebooted and the user will be presented the ransom notice. ...

Avira TechBlog: Thanksgiving and according holidays are very close – a time in which many people have the time to do (online) shopping. The cyber criminals are eager for their share, so it’s time to remember some safety measures. We are expecting to see spam and phishing campaigns luring the recipients to visit malicious web sites. These web sites usually look quite legal and official. As precaution, don’t follow links from emails to online stores and online payment systems, but use bookmarks or type in the addresses directly into the browser’s address bar. And of course just visit shops which you already know. Some scams can be identified by very low prices – if they look too good to be true, they usually are! ...
With the expanding amounts of storage available on cell phones, mp3 players, digital cameras, and gaming devices it’s no surprise that malware is increasingly being transmitted over USB. avast! Software is reporting that out of 700,000 attacks reported by its Community IQ system in October, one in eight were exchanged over USB connections. “Cyber-criminals are taking advantage of people’s natural inclination to share with their friends and the growing memory capacity of USB devices,” says avast! virus analyst Jan Sirmer. ...

Avira TechBlog: Adobe warns of a new vulnerability in Flash Player and in Reader. The problem is within authplay.dll and the corresponding .lib in the Unix versions. It allows attackers to inject malicious code like Trojans with specially prepared documents or Flash objects. The company works on a patch which it plans to release on the 9th of November. Until then, deleting the authplay library helps to prevent a successful attack. Flash or Reader will crash then when a file requests the services from authplay, but this is clearly better than having an infected system. ...

**Mac: Hi PC, I’m not feeling so hot today… ** PC: Oh, I know ALL about that. I think you have a virus! Security experts by and large agree that security via obscurity is not a wise model for protecting customers over the long term. That’s exactly the model Apple has employed successfully for some time now. However, its luck finally appears to be running short. ...
Windows is an attractive platform for the malware writers, in part, because of the sheer number of users. As Microsoft creep towards making their offerings more secure, applications are increasingly becoming the focus for vulnerability exploitation. Like Windows, Adobe products are a default software choice for most users. The bad guys know this and realize that its profitable to scrutinize their applications for exploitable vulnerabilities and create malware to take advantage of the fact. ...
