Cyber criminals are constantly looking for new and sophisticated ways in which to avoid being detected and successfully perform their malicious attacks. This was most evident in the past few years, apart from the rise in ransomware attacks, there has also been an increase in the number of file-less attacks. File-less attacks pose a threat to organizations and challenge security solutions due to the use of sophisticated attack techniques and various non-executable file formats.
There are a few reasons for the increase in file-less attacks. First, the fact that the malicious logic of the attack often occurs in memory, makes traditional static detection insufficient. Second, they complicate post event analysis, as it’s easy for attackers to hide behind. In response, the security industry hasn’t remained idle, and various security solutions have extended their capabilities to combat these types of threats.
