Businesses Scramble Amid New Ransomware Attack – By Adam Zuchetti at My Business
June 2017

Another devastating ransomware attack has caused havoc worldwide, with security experts again warning SMEs they are a primary target.

 

Many SME owners fall into the trap of believing they are not a focus for ransomware and other cyber attacks because of their small size. However, it is this exact mentality that often makes SMEs the primary target of fraudsters.

Just a month after the WannaCry attack left businesses and government organisations around world, including the UK health service, in chaos, a new ransomware called Petya has been detected, which could prove as devastating, or even moreso, than its predecessor – particularly since Australia escaped largely unscathed from the WannaCry attack.

“The rapid pace of this new Petya ransomware attack points at another worm that can spread from computer to computer by itself,” explains Steve Malone of Mimecast.

“This new outbreak once again highlights the disruptive power of ransomware like never before. Simply by encrypting and blocking access to files, critical national services and valuable business data can be damaged.”

 

How To Protect Your Business

“Unlike WannaCry which encrypts a computer’s files, however, the Petya ransomware encrypts a segment of the hard drive that renders the entire computer inoperable. Older legacy systems and critical infrastructure are particularly vulnerable to this attack,” Fortinet said in a statement issued in response to the new attack.

“The patch for this vulnerability was issued by Microsoft earlier this year. We advise organisations to update their systems immediately.”

IBM Security has the following advice for protecting your business from Petya and other cyber threats:

  • Ensure systems are patched (MS17-010) and all antivirus programs are up-to-date.
  • Determine if backup systems are effectively configured.
  • Restore only from secure backups with known safe snapshots or re-image systems completely.
  • Isolate any unpatched systems to prevent lateral movement of Petya.
  • Verify effective monitoring of all critical systems and networks.
  • Create or maintain regular reviews of privileged credential protection to prevent further access via legitimate tools across a network.
  • Review incident response and contingency plans.
