Security News > 2023 > June > Exploit released for MOVEit RCE bug used in data theft attacks

Horizon3 security researchers have released proof-of-concept exploit code for a remote code execution bug in the MOVEit Transfer managed file transfer solution abused by the Clop ransomware gang in data theft attacks.

With the release of this RCE PoC exploit, more threat actors will likely move quickly to deploy it in attacks or create their own custom versions to target any unpatched servers left exposed to Internet access.

Given the widespread media coverage of the attacks exploiting the vulnerability, it is expected that the number of unsecured MOVEit Transfer servers on the internet has sharply decreased since Clop began exploiting the bug.

The Clop ransomware gang has claimed responsibility for the data-theft attacks exploiting the CVE-2023-34362 MOVEit Transfer zero-day in a message sent to Bleepingomputer, attacks that allegedly impacted "Hundreds of companies."

Clop was also linked to the attacks by Microsoft, who attributed this data theft campaign to the Lace Tempest hacking group, which overlaps with FIN11 and TA505 activity.

The list of organizations that have disclosed data breaches following these attacks includes, among others, the EY British multinational, the Irish Health Service Executive public healthcare system, UK-based provider of payroll and HR solutions Zellis and some of its customers.
