Seagate Phish Exposes All Employee W-2’s

Posted on by

Email scam artists last week tricked an employee at data storage giant Seagate Technology into giving away 2015 W-2 tax documents on all current and past employees, KrebsOnSecurity has learned. W-2 forms contain employee Social Security numbers, salaries and other personal data, and are highly prized by thieves involved in filing phony tax refund requests with the Internal Revenue Service (IRS) and the states.

A number of credit unions say they have experienced an unusually high level of debit card fraud from the breach at nationwide fast food chain Wendy’s, and that the losses so far eclipse those that came in the wake of huge card breaches at Target and Home Depot.

Thieves Nab IRS PINs to Hijack Tax Refunds

Posted on by

Last year, KrebsOnSecurity warned that the Internal Revenue Service’s (IRS) solution for helping victims of tax refund fraud avoid being victimized two years in a row was vulnerable to compromise by identity thieves. According to a story shared by one reader, the crooks are well aware of this security weakness and are using it to revisit tax refund fraud on at least some victims two years running — despite the IRS’s added ID theft protections.

IRS: 390K More Victims of IRS.Gov Weakness

Posted on by

The U.S. Internal Revenue Service (IRS) today sharply revised previous estimates on the number of citizens that were hit by tax refund fraud since 2014 thanks to a security weakness in the IRS’s own Web site. According to the IRS, at least 724,000 citizens were victims of refund fraud after crooks figured out how to abuse a (now defunct) IRS Web site feature called “Get Transcript” to steal victim’s prior tax da Continue reading IRS: 390K More Victims of IRS.Gov Weakness→

Breached Credit Union Comes Out of its Shell

Posted on by

Notifying people and companies about data breaches often can be a frustrating and thankless job. Despite my best efforts, sometimes a breach victim I’m alerting will come away convinced that I am not an investigative journalist but instead a scammer. This happened most recently this week, when I told a California credit union that its online banking site was compromised and apparently had been for nearly two months.

The Lowdown on the Apple-FBI Showdown

Posted on by

Many readers have asked for a primer summarizing the privacy and security issues at stake in the the dispute between Apple and the U.S. Justice Department, which last week convinced a judge in California to order Apple to unlock an iPhone used by one of assailants in the recent San Bernardino massacres. I don’t have much original reporting to contribute on this important debate, but I’m visiting it here because it’s a complex topic that deserves the broadest possible public scrutiny.

Dell to Customers: Report ‘Service Tag’ Scams

Posted on by

Computer maker Dell is asking for help in an ongoing probe into the source of customer information that appears to have somehow landed in the laps of fraudsters posing as Dell computer support technicians. KrebsOnSecurity readers continue to report being called by scammers posing as Dell support personnel who offer “proof” that they’re with Dell by rattling off the unique Dell “service tag” code printed on each Dell customer’s PC or laptop, as well as information from any previous (legitimate) service issues the customer may have had with Dell.

This is Why People Fear the ‘Internet of Things’

Posted on by

Imagine buying an internet-enabled surveillance camera, network attached storage device, or home automation gizmo, only to find that it secretly and constantly phones home to a vast peer-to-peer (P2P) network run by the Chinese manufacturer of the hardware. Now imagine that the geek gear you bought doesn’t actually let you block this P2P communication without some serious networking expertise or hardware surgery that few users would attempt.

The Great EMV Fake-Out: No Chip For You!

Posted on by

Many banks are now issuing customers more secure chip-based credit cards, and most retailers now have card terminals in their checkout lanes that can handle the “dip” of chip-card transactions (as opposed to the usual swipe of the card’s magnetic stripe). But comparatively few retailers actually allow chip transactions: Most are still asking customers to swipe the stripe instead of dip the chip. This post will examine what’s going on here, why so many merchants are holding out on the dip, and where this all leaves consumers. Continue reading The Great EMV Fake-Out: No Chip For You!→
