Ransomware: play claims Sigma Plastics Group (US) — Manufacturing

On August 1, 2026, the ransomware group "play" claimed responsibility for a cyberattack against Sigma Plastics Group, a US-based manufacturing company. The claim was published on the ransomware live data leak site, indicating that the group has exfiltrated data and is threatening to release it unless a ransom is paid. This is a breach notification event under the BREACH framework, meaning the incident has been publicly disclosed and is now a matter of record for regulatory and risk assessment purposes.

The primary affected organization is Sigma Plastics Group, which operates in the plastics and packaging manufacturing sector. However, the impact extends to their business partners, suppliers, and customers, particularly those in the EU who may process personal data under GDPR. Any third-party vendors handling data on behalf of Sigma Plastics could also face downstream exposure. Manufacturing firms are increasingly targeted due to their reliance on operational technology and supply chain interdependencies.

Compliance teams should immediately verify whether their organization has any data-sharing or service agreements with Sigma Plastics Group. If so, conduct a risk assessment to determine if personal data was involved and whether notification to supervisory authorities is required under GDPR within 72 hours. Additionally, review your incident response plan to ensure ransomware scenarios are covered, and confirm that backups are isolated and tested. Finally, monitor the ransomware live source for any leaked data that may pertain to your organization, and update your third-party risk register accordingly.
