The Cl0p ransomware group has begun the publication of pilfered information from targeted organizations on its leak portal, following an earlier warning directed towards victims of the MOVEit vulnerability data breach.
On August 10, the hacker collective posted a message particularly directed at those victims who had refrained from admitting data breaches within their organizational framework.
The group had also extended an offer of a “significant discount,” in a bid to encourage the victims to comply to their demands.
Cybersecurity analyst Dominic Alvieri shared a screenshot on Twitter displaying the list of victim companies, accompanied by the pilfered data following the security breach. “Clop completes another round of torrents,” read the post.
Among the companies listed by Cl0p were Norton, Stockman Bank, and Cadence Bank, among several others.
Clop threatens to leak MOVEit victims’ data
Clop victims data leak post read that some companies did not respond to the ransomware threats and thus they offered a final deadline of August 15, 2023. “On 15 August we start publishing of every company on list that do not contact,” the post stated.
They also threatened that the exfiltrated data will be posted on the clear web which will enable all the users to see the exposed data without using specialized tools that are required for dark web surfing.
They claimed to make the data available on TOR and for larger companies, they will create a clear web URL to help Google index the data.
This, the hackers announced would increase the speed of the download as doing so on the dark web took longer.
