The U.S. Justice Department unsealed a 14-count superseding indictment charging 17 people linked to the Mabna Institute, allegedly operating on behalf of the IRGC, in a campaign running since around 2013. The group breached 144 US universities, 42 US companies, 178 foreign universities, 11 foreign companies, and agencies including the Department of Labor, Federal Energy Regulatory Commission, and Hawaii and Indiana state governments, plus UN organizations such as UNICEF, stealing at least 31 terabytes of academic and proprietary data and about 8,000 professor email accounts. The State Department offered a $10 million reward for five individuals including Behzad Mesri, previously indicted for the $6 million HBO extortion; universities spent roughly $20 million on investigation and remediation.

U.S. Sanctions Iran-Linked Hackers Behind Critical Infrastructure Breaches

U.S. Treasury sanctioned nearly 60 Iran-linked entities, including MOIS-affiliated Mabna Institute hackers behind breaches of U.S. critical infrastructure and millions in crypto theft.

The U.S. Treasury launched Operation Economic Outcast, designating nearly 60 Iran-linked entities, individuals, and vessels across nuclear, missile, oil, cyber, and digital asset networks. Five sanctioned individuals are members of the Tehran-based Mabna Institute indicted last week; three allegedly breached and exfiltrated data from U.S. energy, defense, healthcare, IT, and financial organizations since late 2023. TRM Labs traced roughly $16.8 million across 30 wallets tied to the members, and the State Department announced a reward of up to $10 million. The action follows Iranian hacking of FBI Director Kash Patel's email and attacks on over 30 U.S. water and wastewater utilities.

Treasury sanctions alleged Iranian hackers as part of ‘economic D

US Treasury sanctioned four Iranians linked to MOIS-directed hacks that compromised and exfiltrated data from US critical infrastructure, energy, defense, and financial targets.

The Treasury Department designated four Iranian individuals over alleged hacking and cybertheft against US companies in energy, defense, healthcare, IT, and financial sectors since at least late 2023, as part of an 'economic D-Day' sanctions package. It is the second action in weeks against the group, following an indictment of cybercriminals affiliated with Tehran's Mabna Institute; leadership includes Behzad Mesri, first sanctioned in 2018, and the attacks are described as directed by the Ministry of Intelligence and Security (MOIS). Treasury also expanded secondary-sanction categories across digital assets, technology, gold, aviation, and shipping, and noted some group members pursued personal enrichment, including targeting Iranian companies.

Unauthenticated GraphQL Code Injection in GitLab CE/EE Enables Data Tampering
GitLab has patched a critical (CVSS 9.1) code injection flaw (CWE-94) in how GitLab Community Edition (CE) and Enterprise Edition (EE) process GraphQL directives. Under certain conditions, an unauthenticated remote attacker can abuse a GraphQL directive to modify or delete public projects and user data on affected instances, requiring no privileges or user interaction; the impact is to integrity and availability, not confidentiality. Affected versions span all GitLab CE/EE releases from 18.2 before 18.11.11, 19.0 before 19.0.8, 19.1 before 19.1.6, and 19.2 before 19.2.4, which covers self-managed installations as well as the same codebase that powers the GitLab.com SaaS. News reports indicate the flaw came under active exploitation within days of disclosure, and EPSS assigns a 5.8% probability of exploitation within 30 days (93rd percentile). It is not yet listed in CISA's KEV catalog and no public proof-of-concept is known, but defenders should treat it as an actively exploited, unauthenticated, high-impact issue.
