A prolific hacking group known for exploiting software vulnerabilities to strike multiple organizations at once has claimed it stole large volumes of data from nearly 50 companies worldwide, according to a posting on the group’s website, citing targets that include Philips, Shell, Fiserv and GE.

Shell said it was aware of a recent possible incident and that it is working with its security teams and other experts to investigate. Philips said it identified and contained an attempted cybersecurity compromise tied to a specific enterprise server used for internal data, adding that the incident does not affect customer environments.

Fiserv said it is aware of the threat actor’s claims, but based on its review so far it found no evidence that customer, banking, transaction, or personal data had been compromised or that its operating environment had been affected. Reuters reported it could not independently verify what data the hackers allegedly took or how much.

Prior to the claims, Ransom-ISAC issued a July 22 notice warning the group was exploiting vulnerabilities in PTC Windchill and FlexPLM, software used in engineering and manufacturing processes, and one security leader said some companies started receiving notices from Cl0p on July 19 or July 20.
