Fileless malware is a type of malicious software that is able to bypass most security measures by residing within a user’s PC, exploiting existing systems including the RAM and registry.

This year has seen a reported 265% increase in fileless malware threats compared to the first half of 2018. Increasingly sophisticated in its delivery and difficult to detect, fileless malware has become a major security concern for businesses across all sectors.

Preventing permanent damage to your business

With detection of fileless malware a challenging endeavour, prevention is a strong first step to reducing the risk of permanent damage to your business. This starts with proper user training.

“Fundamentally, the biggest security-related challenge is the vulnerability that sits in the chair,” said Dan Kent, Head of Technical for Fitzrovia IT, a leading IT support company in London.

“People – human error – are typically the catalyst for a PC getting a virus. That’s why end-user training is so important. You need to make sure your staff know what to look out for and how to recognise when something is not right,” he said.

In addition to end-user training, it is essential to consistently review your company’s IT security policies, taking into consideration:

  • Do you have a strong disaster recovery plan in place?
  • Is your business Cyber Essentials accredited?
  • If your company has a ‘Bring Your Own Device’ policy, do you have proper MDM and Security policies installed?
  • Are you working with a dedicated IT support provider?

Keeping your systems properly patched and up to date can also prevent exploitation of vulnerabilities by fileless malware.  

“All these things matter and can make a difference, no matter how small,” said Dan. “All areas of security must be aligned in order to prevent large-scale breaches and irreversible damage.”
