Citing “extraordinary cooperation” with the government, a court in Alaska on Tuesday sentenced three men to probation, community service and fines for their admitted roles in authoring and using “Mirai,” a potent malware strain used in countless attacks designed to knock Web sites offline — including an enormously powerful attack in 2016 that sidelined this Web site for nearly four days.
In December 2017, the U.S. Department of Justice announced indictments and guilty pleas by three men in the United States responsible for creating and using Mirai, a malware strain that enslaves poorly-secured “Internet of Things” or IoT devices like security cameras and digital video recorders for use in large-scale cyberattacks.
The FBI and the DOJ had help in their investigation from many security experts, but this post focuses on one expert whose research into the Dark Web and its various malefactors was especially useful in that case. Allison Nixon is director of security research at Flashpoint, a cyber intelligence firm based in New York City. Nixon spoke with KrebsOnSecurity at length about her perspectives on IoT security and the vital role of law enforcement in this fight.
The U.S. Justice Department on Tuesday unsealed the guilty pleas of two men first identified in January 2017 by KrebsOnSecurity as the likely co-authors of Mirai, a malware strain that remotely enslaves so-called “Internet of Things” devices such as security cameras, routers, and digital video recorders for use in large scale attacks designed to knock Web sites and entire networks offline (including multiple major attacks against this site).
On September 22, 2016, this site was forced offline for nearly four days after it was hit with “Mirai,” a malware strain that enslaves poorly secured Internet of Things (IoT) devices like wireless routers and security cameras into a botnet for use in large cyberattacks. Roughly a week after that assault, the individual(s) who launched that attack — using the name “Anna Senpai” — released the source code for Mirai, spawning dozens of copycat attack armies online.
After months of digging, KrebsOnSecurity is now confident to have uncovered Anna Senpai’s real-life identity, and the identity of at least one co-conspirator who helped to write and modify the malware.
