Are You Scared of Fileless Ransomeware Attack ? Know how to Keep Yourself Safe

[vc_row][vc_column][vc_column_text]

Many of the global companies, banks, and even some government organizations are struggling to protect everything from the newest type of threat from “Wannacry Ransomeware blackhat hackers / cyber criminals” that scared the whole world — Fileless Ransomware. The new version of ransomware has arrived — it’s stealthy, almost impossible to detect and is forcing every vulnerable organization to pay the ransom demand to cyber criminals. These attacks are called “fileless” or non-malware ransomware attacks in which the attack executes malicious commands or codes with Microsoft’s PowerShell.

I have been asked by a few people regarding this nightmare, so I have decided to share my knowledge and write this article, explaining how these attacks work in depth. On top of that, I’d like to discuss the prevention techniques. As people are going crazy and trust me they are really scared.

It’s really important to mention that Non-malware or file-less ransomware (unlike some traditional ransomware) does not use any of the files to encrypt your data, but instead it writes scripts/macros which originate from PowerShell to encrypt the files.

Fileless malware is a unique type of software  and it’s really difficult to detect because the malicious code is embedded into the native scripting language or written straight into the computer’s RAM, where it hides in isolated spots within the computer’s memory. It’s not written on disk nor does the malicious code rely on the hard drive to run these commands.

What are the biggest problems with Ransomeware attack?

 –  Any kind of antivirus software would be useless as there are no such code written yet to kill / stop these Ransomeware Program. But Lets hope for the best.

 –  This ransomware strain allows cyber criminals to have access to your systems. This means that they can infiltrate your computers, steal your information and encrypt your files without your IT staff even knowing. 

 –  It can lead to more attacks. As the cyber criminals are writing scripts they’re also gathering as much data from the victim’s computer as possible.

Prevention techniques:

Even if we can’t protect our systems to be 100% secure, there are certain measures you can take to significantly reduce the risk:

  • Make regular Back-ups of your important data to another disk that will not be connected to the Internet . Disable auto-start of every macro and avoid suspicious files.Be smart and filter your e-mails and block them if they look suspicious to you.
  • Never visit a website that looks suspicious and never download any add-ons, plugins which are usually fake.
  • Configure your windows accounts to be limited as possible and don’t give them administrator rights.
  • Use good software or hardware firewall and monitor your traffic from time to time to prevent any probable ransomeware attack
  • Restrict user write permissions.
  • Limit the privileges for PsExec.exe
  • Install a process manager and monitor your processes from time to time.
  • Train your staff to be informed about the possible attacks
