TCP 130: Checkmarx Data Dump, Linux Copy Fail, ShinyHunters Claims and Security Updates

Summary
This weekly roundup covers Checkmarx’s confirmed 96GB data dump linked to credentials from the TeamPCP-attributed Trivy compromise, Copy Fail Linux LPE, ShinyHunters’ claims involving Medtronic and Carnival, and security industry and insurance findings.
Key points
- Checkmarx confirmed that Lapsus$ published a 96GB archive of its data. The article links access to credentials stolen in the Trivy supply-chain compromise attributed to TeamPCP.
- Researchers disclosed Copy Fail, a Linux local privilege escalation involving the shared page cache. The article says it can enable container or tenant boundary crossing and is not remotely exploitable by itself.
- ShinyHunters claimed to have data from Medtronic and Carnival. Medtronic confirmed a corporate IT incident but did not validate the claimed record count; Carnival attributed its incident to phishing of a single user account.
- Google announced new SecOps agents and agent-governance capabilities; Wiz also announced integrations and AI security features across cloud, development and agent platforms.
- Resilience analysis of manufacturing claims from March 2021 to February 2026 attributed 26% of losses to misconfigured MFA and 90% of total loss to ransomware, which represented 12% of claims.
- Amazon described RuleForge, an AI-assisted detection-rule pipeline with separate generation and evaluation models, synthetic testing, honeypot validation and human approval.
Article Details
- Event Type
- Cybersecurity news roundup covering a software supply-chain compromise and data leak, claimed data breaches, a Linux local privilege-escalation vulnerability, and security product announcements.
- Impact
- Checkmarx confirmed that Lapsus$ published a 96GB archive containing source code, employee data, API keys, and database credentials after attackers used credentials stolen in the Trivy supply-chain compromise attributed to TeamPCP. The article also reports ShinyHunters’ breach claims involving Medtronic and Carnival/Holland America; Medtronic did not validate the claimed record count, and Carnival said the incident involved a phished user account while its assessment continued. Copy Fail was disclosed as a local Linux privilege-escalation flaw with a public PoC and potential container and tenant boundary impacts. Separately, Resilience’s manufacturing claims analysis attributed 26% of losses to misconfigured MFA and 90% of total loss to ransomware.
