It has been crystal clear over these years with the increase in a number of cyber-attacks of an equally unique kind making it almost impossible for the out-dated or conventional security mechanisms to intercept and fight.
As if a single one-of-a-kind cyber-attack tool wasn’t enough, the threat actors now are laden with polymorphic tactics up their sleeves. Per sources, an entirely new version of a threat could be created every time after infection.
After "polymorphism" became apparent, the vendors as per reports engineered “generic signatures” had numerous variants in them. But the cyber-cons always managed to slip in a new kind.
This is when the malware authors came up with a concept of fileless attacking. They fabricated malware that didn’t need files to infect their targets and yet caused equal damage.
Per sources, the most common fileless attacks use applications, software, or authorized protocol that already exists on the target device. The first step is a user-initiated action, followed by getting access to the target’s device memory which has been infected by now. Here the malicious code is injected via the exploitation of Windows tools like Windows Management Instrumentation and PowerShell.
Per reports, the Modus Operandi of a fileless attack is as follows:It begins with a spam message which doesn’t look suspicious at all and when the unaware user clicks on the link in it they are redirected to a malicious website.The website kicks-off the Adobe Flash.That initiates the PowerShell and Flash employs the command line to send it instructions and this takes place inside the target device’s memory.The instructions a ..
