Hackers hit Tesco as over 2,200 accounts compromised

Tesco, an international supermarket chain, has been forced to deactivate online customer accounts after hackers took aim at its systems.

The company confirmed to The Guardian on Friday that over 2,200 of its accounts were compromised. Interestingly, it's believed that the hackers didn't actually break into its systems, but instead used data collected from other hacks to see if they could get any hits. The affected accounts used the same username and password combination as those in previous hacks, allowing the hackers to break in.

Rather than snoop around, however, the hackers posted the compromised accounts online, … Read more

Snapchat hack spams users with smoothie photos

Snapchat is combating yet another security issue, and it's a juicy one.

In a story posted late Tuesday, Wired editor Joe Brown said his Snapchat friends were asking why he was sending them messages with photos of fruit smoothies. That was a surprise to Brown because he hadn't sent any such messages. Other Snapchatters have since complained about receiving these same messages, according to a Twitter search.

The messages serve up a URL for a company called Snapfroot, which then redirects the recipient to an AllRecipes.com page for a "Berry Delicious" smoothie. The spam outbreak … Read more

Sochi hack report 'fraudulent,' security researcher charges

A report this week that attendees at the Sochi Winter Olympics were being hacked the second they booted up their electronic devices is "100 percent fraudulent," a security researcher charged Thursday.

Robert Graham of Errata Security was criticizing a report by NBC reporter Richard Engel on the safety of logging onto Russian networks. Engel reported that during a security test at cafe with a security expert, "before we even finished our coffee" the bad actors had hit, downloading malware and "stealing my information and giving hackers the option to tap or even record my phone … Read more

Heating vents may have given Target hackers their opening

The Target hack that shook the American credit card industry and delivered up to 110 million customer records to the bad guys was reportedly successful thanks to a side-door left open by a Target contractor.

The hackers were able to get credentials for Target's network stolen from Fazio Mechanical Services, a heating, ventilation, and air conditioning (HVAC) company, according to independent security reporter Brian Krebs. They were first used to access Target's network on November 15, 2013.

Fazio President Ross Fazio told Krebs that the US Secret Service, which customarily investigates these kinds of cases, visited his company'… Read more

Sochi visitors entering hacking 'minefield' by firing up electronics

If you've read anything about the Sochi Olympics over the last few days, there's as much a chance that it was about broken and unfinished infrastructure as actual athletics. And now comes word that hackers are having a field day with unsuspecting Sochi visitors.

According to an NBC News report, unprepared Olympics attendees are being hacked the second they fire up their electronic devices.

NBC reporter Richard Engel worked with a security expert to set up two test computers in order to see just how quickly he'd be attacked when logging onto Russian networks. But, he reported, … Read more

Target works on security-heavy credit cards, after breach

Target is still reeling from the massive security breach, which affected as many as 110 million customers. Now, as the retailer gets back on its feet, it's becoming more security focused.

Target Chief Financial Officer John Mulligan wrote an opinion piece for The Hill on Monday saying that the company was speeding up its implementation of high-security credit cards.

The credit cards come embedded with a tiny microprocessor chip, which is said to beef up security and make it more difficult for cybercriminals to access user data. Target had already begun work on the cards before the hack, but … Read more

Has a jealous lover hired hackers to get into your e-mail?

On seeing a happy, loving couple my first reaction is always one of teary admiration. My second, which arrives very quickly, is sniffy suspicion.

"Can they really be this happy?" I wonder. "How is it possible after 18 months? Aren't they bored of each other yet? She's a lot better-looking than he is, so, well, at least one of her eyes must wander." These are just some of the life-addled thoughts that pass into my consideration.

I was moved, therefore, to hear that last week federal prosecutors charged two Arkansas men for allegedly helping … Read more

SpyEye malware inventor pleads guilty to bank fraud

The alleged architect of the bank-hacking malware SpyEye, which is said to have infected 1.4 million computers, has pleaded guilty to conspiracy to commit wire and bank fraud. The US Department of Justice announced Tuesday that Russian national Aleksandr Andreevich Panin was the primary developer and distributor of SpyEye.

"As several recent and widely reported data breaches have shown, cyber-attacks pose a critical threat to our nation's economic security," US Attorney of the Northern District of Georgia Sally Quillian Yates said in a statement. "Today's plea is a great leap forward in our campaign … Read more

Snapchat's new verification already hacked

In about the time it takes to order of one of those vile pizza replicas from Domino's, one security researcher has proven how Snapchat's new verification system can be hacked.

Steve Hickson used his knowledge of how computers recognize images and template matching to show how a computer could fool Snapchat's new Captcha-style image verification that debuted on Wednesday.

"I spent around 30 minutes writing up some code" to perform the automated recognition and selection task, Hickson said. "With very little effort, my code was able to 'find the ghost' in the above example … Read more
