U.S. prosecutors have expanded an eight-year-old cyber case tied to Iran’s Islamic Revolutionary Guard Corps, charging 17 people connected to the Iran-based Mabna Institute in a 14-count second superseding indictment unsealed Aug. 18. The action adds eight defendants and links six of them—including Behzad Mesri, previously charged separately in 2017—to the HBO breach in which hackers allegedly stole unreleased episodes, scripts and other proprietary material and sought a Bitcoin ransom that rose from $5.5 million to about $6 million before content was leaked online. Officials have not alleged that HBO paid. Prosecutors say Mabna operated as a private firm conducting intrusions for the IRGC and other Iranian clients, targeting more than 100,000 professor accounts, compromising about 8,000 and stealing at least 31.5 terabytes of academic data and intellectual property through activity that continued until at least December 2017, while related private-sector and government attacks allegedly caused more than $20 million in investigation and remediation costs. The State Department’s Rewards for Justice program is offering up to $10 million for information leading to the location of five named defendants.
