What Is A Fileless Malware Attack?

MetroTech Managed IT Services, Clearwater, FL, Fileless Malware Attack

With the rise of Russian hacking hitting U.S. businesses, there’s a type of malware called fileless malware being used to infiltrate networks at an alarming frequency. A fileless malware attack doesn’t use actual computer files to infect your systems. Instead, it buries itself inside your computer’s RAM. It leaves no trace of its existence, making it extremely difficult to detect or remove. Digital enemies know the common techniques being employed by networks to block them and in response, they are crafting more advanced ways to penetrate security systems, including fileless malware.

How Harmful Is A Fileless Malware Attack To My Business?

If the malware is not discovered by an expert cyber security team, it can do irreparable damage to a company’s technology systems, such as:

  • It can cause network and systems crashes throughout your company
  • It can act as a backdoor for other malware to easily penetrate your network
  • It can bog down CPU memory and take up valuable time within your business operations
  • As with other malware, it can be designed to steal data
  • Modification or deletion of files
