The Janicab.A family of malware is a dangerous group of Trojans that targets both computer systems running Windows or Mac OS X. As more computer users purchase and make use of the Mac OS X operating system, it becomes a more attractive target for malware developers. Janicab.A and other variants in this family are related to black hat tactics used to profit at the expense of computer users. There are several unusual characteristics of Janicab.A. Janicab.A is connected to a malicious YouTube page that is used to force computer users to establish a connection with Janicab.A's Command and Control server. Janicab.A has various tactics that allow Janicab.A to hide from detection by PC security analysts.

The Unusual Target of the Janicab.A

Janicab.A was first observed in action in July of 2013. Janicab.A attracted the attention of security analysts because Janicab.A targeted computer systems with the Mac OS X operating system. Since Trojans that target Mac computer systems are considerably more unusual than their Windows counterparts, whenever one surfaces in widespread attacks it immediately attracts the attention of PC security researchers. One aspect of Janicab.A that immediately attracted attention is that Janicab.A uses a digital signature containing a valid Apple Developer ID. Another aspect of Janicab.A that attracted attention is that its code is written in a particularly clever way that allows criminals to disguise the Janicab.A executable file as a PDF document. Janicab.A attacks may also affect computer systems running the Windows operating system. Janicab.A exploits a known vulnerability in Microsoft Windows that allows criminals to install a malicious script written in Visual Basic. This vulnerability was patched in 2012, meaning that it is possible to avoid Janicab.A attacks by ensuring that your operating system is fully up to date.

Additional Information Concerning Janicab.A

It seems that the Janicab.A infection may be unfinished. This is because Janicab.A redirects to various Command and Control servers, some which display Web pages that are not entirely finished. In fact, PC security researchers suspect that the version of Janicab.A being observed in current attacks may be a beta version of a malware infection in development. To prevent Janicab.A attacks, ESG security researchers recommend being careful when installing new software and using a strong anti-malware program to protect your computer.
