The D1R ransomware gang claims to have stolen sensitive engineering data from Bosch by exploiting an alleged vulnerability in Synopsys, a technology provider. The gang has given Bosch 11 days to negotiate before leaking the data, which includes potentially proprietary hardware designs. Synopsys has denied any breach, stating it found no evidence supporting D1R's claims and has not been contacted by the attackers. The ransomware group also alleges to have accessed a database of 40,000 corporate clients from Synopsys. Bosch has acknowledged the situation and is working on strengthening its cybersecurity measures. The claims remain unverified, and the scope of the breach is still uncertain. The incident highlights the risks associated with supply chain vulnerabilities.
