Comments Off on Four Steps to Protect Your Small and Medium-Sized Business from Ransomware
In the aftermath of the WannaCry ransomware outbreak last month, your systems could still be at risk from other threats that exploit underlying Microsoft Windows vulnerabilities. This week, a new attack identified as a variant of the first, has continued to exploit these and other weaknesses, to attack systems worldwide. The infection has now spread to 60 countries, and continues to actively search for more victims.
The new ransomware attack, encrypts the victim’s hard drive, and demands a ransom to be paid in Bitcoin. However, the new malware is proving to be more sophisticated than WannaCry in terms of scope, ease of neutralizing it. This attack spread rapidly using common Microsoft system administration tools, which are not recognized as malware by traditional security defenses.
The victim receives a phishing email, then the ransomware is activated by underlying vulnerabilities in Microsoft operating systems.
Of great importance: even if victims pay the ransom, their files are not unlocked. The only way to survive the attack, is to have a recent off-site backup of all systems.
Four Steps to Protect Your Organization from Ransomware:
Obsolete versions of Microsoft Windows continue to be particularly vulnerable. Update all versions of Microsoft operating systems, and server systems.
