Israeli Online Attack Service ‘vDOS’ Earned $600,000 in Two Years

September 8, 2016

vDOS — a so-called “booter” service that has earned in excess of $600,000 over the past two years helping customers coordinate more than 150,000 so-called distributed denial-of-service (DDoS) attacks designed to knock Web sites offline — has been massively hacked, spilling secrets about tens of thousands of paying customers and their targets.

The vDOS database, obtained by KrebsOnSecurity.com at the end of July 2016, points to two young men in Israel as the principle owners and masterminds of the attack service, with support services coming from several young hackers in the United States.

The Limits of SMS for 2-Factor Authentication

A recent ping from a reader reminded me that I’ve been meaning to blog about the security limitations of using cell phone text messages for two-factor authentication online. The reader’s daughter had received a text message claiming to be from Google, warning that her Gmail account had been locked because someone in India had tried to access her account. The young woman was advised to expect a 6-digit verification code to be sent to her and to reply to the scammer’s message with that code.

The massive data breach at the U.S. Office of Personnel Management (OPM) that exposed background investigations and fingerprint data on millions of Americans was the result of a cascading series of cybersecurity blunders from the agency’s senior leadership on down to the outdated technology used to secure the sensitive data, according to a lengthy report released today by a key government oversight panel.

Location Privacy: The Purview of the Rich and Indigent

I’d just finished parking my car in the covered garage at Reagan National Airport just across the river from Washington, D.C. when I noticed a dark green minivan slowly creeping through the row behind me. The vehicle caught my attention because its driver didn’t appear to be looking for an open spot. What’s more, the van had what looked like two cameras perched atop its roof — one of each side, both pointed down and slightly off to the side.

I had a few hours before my flight boarded, so I delayed my walk to the terminal and cut through several rows of cars to snag a video of the guy moving haltingly through another line of cars. I approached the driver and asked what he was doing. He smiled and tilted the lid on his bolted-down laptop so that I could see the pictures he was taking with the mounted cameras: He was photographing every license plate in the garage (for the record, his plate was a Virginia tag number 36-646L).

‘Flash Hijacks’ Add New Twist to Muggings

A frequent crime in Brazil is a scheme in which thieves kidnap people as they’re leaving a bank, and free them only after they’ve visited a number of ATMs to withdraw cash. Now the crooks have introduced a new time-saving wrinkle into this scam: In these so-called “flash hijackings” the thieves pull out a wireless card reader, swipe a few debit or credit transactions with the victim’s card, and then release the individual.

Earlier this month, KrebsOnSecurity published The Reincarnation of a Bulletproof Hoster, which examined evidence suggesting that a Web hosting company called HostSailor was created out of the ashes of another, now-defunct hosting firm notorious for harboring spammers, scammers and other online ne’er-do-wells. Today, HostSailor’s lawyers threatened to sue this author unless the story is removed from the Web.

In March 2013, a coalition of spammers and spam-friendly hosting firms pooled their resources to launch what would become the largest distributed denial-of-service (DDoS) attack the Internet had ever seen. The assault briefly knocked offline the world’s largest anti-spam organization, and caused a great deal of collateral damage to innocent bystanders in the process. Here’s a never-before-seen look at how that attack unfolded, and a rare glimpse into the shadowy cybercrime forces that orchestrated it.

United Airlines Sets Minimum Bar on Security

United Airlines has rolled out a series of updates to its Web site that the company claims will help beef up the security of customer accounts. But at first glance, the core changes — moving from a 4-digit PINs to password and requiring customers to pick five different security questions and answers — may seem like a security playbook copied from Yahoo.com, circa 2009. Here’s a closer look at what’s changed in how United authenticates customers, and hopefully a bit of insight into what the nation’s fourth-largest airline is trying to accomplish with its new system.

A Life or Death Case of Identity Theft?

Identity thieves have perfected a scam in which they impersonate existing customers at retail mobile phone stores, pay a small cash deposit on pricey new phones, and then charge the rest to the victim’s account. In most cases, switching on the new phones causes the victim account owner’s phone(s) to go dead. This is the story of a Pennsylvania man who allegedly died of a heart attack because his wife’s phone was switched off by ID thieves and she was temporarily unable to call for help.
