New T-Mobile Breach Affects 37 Million Accounts

Thinking of Hiring or Running a Booter Service? Think Again.

January 17, 2023

Most people who operate DDoS-for-hire services attempt to hide their true identities and location. Proprietors of these so-called “booter” or “stresser” services — designed to knock websites and users offline — have long operated in a legally murky area of cybercrime law. But until recently, their biggest concern wasn’t avoiding capture or shutdown by the feds: It was minimizing harassment from unhappy customers or victims, and insulating themselves against incessant attacks from competing DDoS-for-hire services.

And then there are booter store operators like John Dobbs, a 32-year-old computer science graduate student living in Honolulu, Hawaii. For at least a decade until late last year, Dobbs openly operated IPStresser[.]com, a popular and powerful attack-for-hire service that he registered with the state of Hawaii using his real name and address. Likewise, the domain was registered in Dobbs’s name and hometown in Pennsylvania.

The only work experience Dobbs listed on his resume was as a freelance developer from 2013 to the present day. Dobbs’s resume doesn’t name his booter service, but in it he brags about maintaining websites with half a million page views daily, and “designing server deployments for performance, high-availability and security.”

In December 2022, the U.S. Department of Justice seized Dobbs’s IPStresser website and charged him with one count of aiding and abetting computer intrusions. Prosecutors say his service attracted more than two million registered users, and was responsible for launching a staggering 30 million distinct DDoS attacks.

Microsoft Patch Tuesday, January 2023 Edition

January 10, 2023

Microsoft today released updates to fix nearly 100 security flaws in its Windows operating systems and other software. Highlights from the first Patch Tuesday of 2023 include a zero-day vulnerability in Windows, printer software flaws reported by the U.S. National Security Agency, and a critical Microsoft SharePoint Server bug that allows a remote, unauthenticated attacker to make an anonymous connection.

Identity Thieves Bypassed Experian Security to View Credit Reports

January 9, 2023

Identity thieves have been exploiting a glaring security weakness in the website of Experian, one of the big three consumer credit reporting bureaus. Normally, Experian requires that those seeking a copy of their credit report successfully answer several multiple choice questions about their financial history. But until the end of 2022, Experian’s website allowed anyone to bypass these questions and go straight to the consumer’s report. All that was needed was the person’s name, address, birthday and Social Security number.

Happy 13th Birthday, KrebsOnSecurity!

December 29, 2022

KrebsOnSecurity turns 12 years old today. That’s a crazy long time for an independent media outlet these days, but then again I’m liable to keep doing this as long as they keep letting me!

Thanks to your readership and support, I was able to spend more time in 2022 on in-depth investigative stories — the really satisfying kind with the potential to affect positive change. Some of that work is highlighted in the 2022 Year in Breaches review below.

The Equifax Breach Settlement Offer is Real, For Now

December 20, 2022

Millions of people likely just received an email or snail mail notice saying they’re eligible to claim a class action payment in connection with the 2017 megabreach at consumer credit bureau Equifax. Given the high volume of reader inquiries about this, it seemed worth pointing out that while this particular offer is legit (if paltry), scammers are likely to soon capitalize on public attention to the settlement money.

Hacked Ring Cams Used to Record Swatting Victims

December 19, 2022

Two U.S. men have been charged with hacking into the Ring home security cameras of a dozen random people and then “swatting” them — falsely reporting a violent incident at the target’s address to trick local police into responding with force. Prosecutors say the duo used the compromised Ring devices to stream live video footage on social media of police raiding their targets’ homes, and to taunt authorities when they arrived.

Six Charged in Mass Takedown of DDoS-for-Hire Sites

December 14, 2022

The U.S. Department of Justice (DOJ) today seized four-dozen domains that sold “booter” or “stresser” services — businesses that make it easy and cheap for even non-technical users to launch powerful Distributed Denial of Service (DDoS) attacks designed knock targets offline. The DOJ also charged six U.S. men with computer crimes related to their alleged ownership of the popular DDoS-for-hire services.

FBI’s Vetted Info Sharing Network ‘InfraGard’ Hacked

December 13, 2022

InfraGard, a program run by the U.S. Federal Bureau of Investigation (FBI) to build cyber and physical threat information sharing partnerships with the private sector, this week saw its database of contact information on more than 80,000 members go up for sale on an English-language cybercrime forum. Meanwhile, the hackers responsible are communicating directly with members through the InfraGard portal online — using a new account under the assumed identity of a financial industry CEO that was vetted by the FBI itself.
