New Delhi, February 7 : Cyber-criminals are exploiting two-year-old vulnerability in Cloud software company VMware for a massive-scale ransomware attack. France's computer emergency response team (CERT-FR) has warned that hackers have been targeting 'VMware ESXi' servers since February 3. WhatsApp Feature Update: Meta-Owned Messaging Platform Likely To Roll Out New Feature To Let Users Share Up to 100 Media on Android Beta.

Italy's national cybersecurity agency ACN also warned of a large-scale ransomware campaign targeting thousands of servers across Europe and North America.

"In the current state of investigations, these attack campaigns seem to have taken advantage of the exposure of ESXi hypervisors which would not have been updated with security patches quickly enough," said CERT-FR. These vulnerabilities allow an attacker to remotely exploit arbitrary code. Twitter Feature Update: ‘For You’ Tab To Stay on Users’ Preferred Timeline on Android and iOS.

According to a Census search, more than 3,200 VMware servers worldwide have been compromised by the ESXiArgs ransomware campaign. France is the most affected country, followed by the US, Germany, Canada and the UK.

A VMware spokesperson told TechCrunch that patches for the vulnerability "were made available to customers two years ago in VMware's security advisory of February 23, 2021."

"Security hygiene is a key component of preventing ransomware attacks, and organisations who are running versions of ESXi impacted by CVE-2021-21974, and have not yet applied the patch, should take action as directed in the advisory," the spokesperson said.

The ransomware campaign is already causing "significant" damage due to the number of unpatched machines. It's not yet clear who is behind the ransomware campaign.
