Safety consultants warn that two high-risk flaws in a preferred distant entry device are being exploited by hackers to deploy LockBit ransomware – days after authorities introduced that they had dismantled the infamous Russia-linked cybercrime gang.
Researchers from cybersecurity corporations Huntress and Sophos advised TechCrunch on Thursday that the 2 had noticed LockBit assaults following exploitation of a set of vulnerabilities impacting ConnectWise ScreenConnect, a distant entry device broadly utilized by IT technicians to supply distant technical help on buyer techniques.
The issues encompass two bugs.

The opposite bug, CVE-2024-1708, is a path traversal vulnerability that can be utilized together with the opposite bug to remotely plant malicious code on an affected system.
In an article on Mastodon On Thursday, Sophos mentioned it noticed “a number of LockBit assaults” following the exploitation of ConnectWise vulnerabilities.
“Two attention-grabbing issues right here: First, as others have famous, ScreenConnect vulnerabilities are actively exploited within the wild. Second, regardless of the police operation towards LockBit, it seems that some associates are nonetheless operational,” Sophos mentioned, referring to the legislation enforcement operation earlier this week that presupposed to destroy LockBit’s infrastructure.
Christopher Budd, director of risk analysis at Sophos used was susceptible.”
Max Rogers, senior director of risk operations at Huntress, advised TechCrunch that the cybersecurity firm has additionally noticed the deployment of LockBit ransomware in assaults exploiting the ScreenConnect vulnerability.
Rogers mentioned Huntress had seen LockBit ransomware deployed on buyer techniques spanning a spread of industries, however declined to call the affected clients.
The LockBit ransomware infrastructure was seized earlier this week as half of a giant worldwide legislation enforcement operation led by the UK’s Nationwide Crime Company.

When requested if the deployment of ransomware was one thing ConnectWise was additionally observing internally, Patrick Beggs, ConnectWise’s chief data safety officer, advised TechCrunch that “it is not one thing we we see as we speak.”
It’s unclear what number of ConnectWise ScreenConnect customers had been affected by this vulnerability, and ConnectWise declined to supply figures. The corporate’s web site claims that the group gives its distant entry expertise to greater than 1,000,000 small and medium-sized companies.
In response to the Shadowserver Basis, a nonprofit group that collects and analyzes knowledge on malicious exercise on the Web, the ScreenConnect flaws are “broadly exploited.” The nonprofit mentioned Thursday in an article onpreviously Twitter, has thus far noticed 643 IP addresses exploiting these vulnerabilities, including that greater than 8,200 servers stay susceptible.
