Why Phone Numbers Stink As Identity Proof

Phone numbers stink for security and authentication. They stink because most of us have so much invested in these digits that they’ve become de facto identities. At the same time, when you lose control over a phone number — maybe it’s hijacked by fraudsters, you got separated or divorced, or you were way late on your phone bill payments — whoever inherits that number can then be you in a lot of places online.

An entrepreneur and virtual currency investor is suing AT&T for $224 million, claiming the wireless provider was negligent when it failed to prevent thieves from hijacking his mobile account and stealing millions of dollars in cryptocurrencies. Increasingly frequent, high-profile attacks like these are prompting some experts to say the surest way to safeguard one’s online accounts may be to disconnect them from the mobile providers entirely.

Expert: IoT Botnets the Work of a ‘Vast Minority’

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.

A half dozen technology and security companies — some of them competitors — issued the exact same press release today. This unusual level of cross-industry collaboration caps a successful effort to dismantle ‘WireX,’ an extraordinary new crime machine comprising tens of thousands of hacked Android mobile devices that was used this month to launch a series of massive cyber attacks. Experts involved in the takedown warn that WireX marks the emergence of a new class of attack tools that are more challenging to defend against and thus require broader industry cooperation to defeat.

Dual-Use Software Criminal Case Not So Novel

“He built a piece of software. That tool was pirated and abused by hackers. Now the feds want him to pay for the computer crooks’ crimes.” The above snippet is the subhead of a story published last month by the Daily Beast titled “FBI Arrests Hacker Who Hacked No One.” The subject of that piece — a 26-year-old American named Taylor Huddleston — faces felony hacking charges connected to two computer programs he authored and sold: An anti-piracy product called Net Seal, and a Remote Administration Tool (RAT) called NanoCore that he says was a benign program designed to help users remotely administer their computers. The author of the Daily Beast story, former black hat hacker and Wired.com editor Kevin Poulsen, argues that Huddelston’s case “raises a novel question: When is a programmer criminally responsible for the actions of his users? Some experts say [the case] could have far reaching implications for developers, particularly those working on new technologies that criminals might adopt in unforeseeable ways.” But a closer look at the government’s side of the story — as well as public postings left behind by the accused and his alleged accomplices — paints a more complex and nuanced picture that suggests this may not be the case to raise that legal question in a meaningful way.

Who is Anna-Senpai, the Mirai Worm Author?


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.
