Malware: Exploring mutex objects A mutex, also called a lock is a program object commonly used to avoid simultaneous access to a resource, such a variable. It’s used in concurrent programming to allow multiple program threads to share the same resource. Mutexs are usually used by malware creators to avoid the infection of a system by different instances of the same malware. When the trojan infects a system, the first step is to obtain a handle to a “named” mutex, if the process fails, then the malware exits.

Everything You Need to Know About âJackpotting,â a New Cyber Attack Targeting ATMs The first reported attack of ATM jackpotting was in 2013 in Mexico. The malware, called Ploutus, was identified as one of the most advanced ATM malware families in recent years, according to FireEye. One of the reasons the attacks took longer to spread to the U.S. is because it may have been easier to get away with physically stealing ATMs and bribing individuals in Latin America than in the U.S., Hummel said.

Malware or legitimate? Comparing two files, side by side. Let's look at firefox.exe, which is a legitimate file, and compare it to olhrwef.exe which is malware. These two files are great candidates for typical legitimate and malware behaviour: firefox.exe was added to FreeFixer's database on the 30 Mar 2009. The most recent search for this file was done on 30 Mar 2009. firefox.exe is located in the 'C:\Program Files\Mozilla Firefox\' folder and has a size of 307704 bytes.

- Heuristic analysis uses a rule-based approach to diagnosing a potentially-oﬀ ending ﬁ le (or message, in the case of spam analysis). As the analyzer engine works through its rule-base, checking the message against criteria that indicate possible malware, it assigns score points when it locates a match.n the second case, the double extension suggests an attempt to pass oﬀ an executable ﬁ le as a non-executable (graphics) ﬁ le, a common virus writer’s trick. In a sense, the opposite of heuristic analysis in AV is not signature scanning, but algorithmic scanning, of which signature scanning is a special case.
