Cl0p Targets 40+ Organizations Through PTC Windchill Flaw

Cl0p claims over 40 organizations including Shell and Philips were breached by exploiting critical RCE CVE-2026-12569 in PTC Windchill and FlexPLM.

Cl0p claims more than 40 organizations were victimized via CVE-2026-12569 (CVSS 9.3), a critical deserialization-based remote code execution flaw in PTC Windchill PDMlink and FlexPLM, affecting releases prior to 11.0 M030; CISA added the flaw to its KEV catalog in June. ReliaQuest found the group deployed a custom web shell that maps vault data, decrypts all credentials in the Windchill keystore, and includes a Java class loader enabling arbitrary code execution, lateral movement, persistence, and large-scale data exfiltration without extra tooling. Named victims include Shell, Philips, Fiserv, Zebra Technologies, Ingersoll Rand, Toast, Mindray, and Apple lens supplier Largan Precision, with stolen data ranging from one gigabyte to multiple terabytes per target. The campaign mirrors Cl0p's earlier mass-exploitation extortion operations against MOVEit, Cleo, GoAnywhere, and Oracle E-Business Suite.

CVE-2026-125699.341%
Unauthenticated RCE in PTC Windchill and FlexPLM
PTC Windchill and FlexPLM contain an improper input validation flaw (CWE-20) with an associated deserialization of untrusted data weakness (CWE-502) that allows an unauthenticated, remote attacker to execute arbitrary code by sending a malicious request over the network. An attacker who can reach a vulnerable Windchill or FlexPLM server can run arbitrary code on it, potentially gaining a foothold for lateral movement; CISA notes the flaw is being used in ransomware campaigns. All organizations running PTC Windchill or FlexPLM are affected, and the available data does not specify affected version ranges. The vulnerability was added to CISA's Known Exploited Vulnerabilities catalog on 2026-06-25 with known ransomware use, and EPSS assigns a 40.6% probability of exploitation within 30 days (99th percentile). No CVSS score or public proof-of-concept is available yet, but the KEV listing confirms exploitation in the wild.
