Facebook Stored Hundreds of Millions of User Passwords in Plain Text for Years

March 21, 2019

Hundreds of millions of Facebook users had their account passwords stored in plain text and searchable by thousands of Facebook employees — in some cases going back to 2012, KrebsOnSecurity has learned. Facebook says an ongoing investigation has so far found no indication that employees have abused access to this data.

Why Phone Numbers Stink As Identity Proof

March 17, 2019

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.

MyEquifax.com Bypasses Credit Freeze PIN

March 8, 2019

Most people who have frozen their credit files with Equifax have been issued a numeric Personal Identification Number (PIN) which is supposed to be required before a freeze can be lifted or thawed. Unfortunately, if you don’t already have an account at the credit bureau’s new myEquifax portal, it may be simple for identity thieves to lift an existing credit freeze at Equifax and bypass the PIN armed with little more than your, name, Social Security number and birthday.

Crypto Mining Service Coinhive to Call it Quits

February 27, 2019

Roughly one year ago, KrebsOnSecurity published a lengthy investigation into the individuals behind Coinhive[.]com, a cryptocurrency mining service that has been heavily abused to force hacked Web sites to mine virtual currency. On Tuesday, Coinhive announced plans to pull the plug on the project early next month.

A Deep Dive on the Recent Widespread DNS Hijacking Attacks

February 18, 2019

The U.S. government — along with a number of leading security companies — recently warned about a series of highly complex and widespread attacks that allowed suspected Iranian hackers to siphon huge volumes of email passwords and other sensitive data from multiple governments and private companies. But to date, the specifics of exactly how that attack went down and who was hit have remained shrouded in secrecy.

This post seeks to document the extent of those attacks, and traces the origins of this overwhelmingly successful cyber espionage campaign back to a cascading series of breaches at key Internet infrastructure providers.

Crooks Continue to Exploit GoDaddy Hole

February 4, 2019

Godaddy.com, the world’s largest domain name registrar, recently addressed an authentication weakness that cybercriminals were using to blast out spam through legitimate, dormant domains. But several more recent malware spam campaigns suggest GoDaddy’s fix hasn’t gone far enough, and that scammers likely still have a sizable arsenal of hijacked GoDaddy domains at their disposal.

Bomb Threat, Sextortion Spammers Abused Weakness at GoDaddy.com

January 22, 2019

Two of the most disruptive and widely-received spam email campaigns over the past few months — including an ongoing sextortion email scam and a bomb threat hoax that shut down dozens of schools, businesses and government buildings late last year — were made possible thanks to an authentication weakness at GoDaddy.com, the world’s largest domain name registrar, KrebsOnSecurity has learned.

Perhaps more worryingly, experts warn this same weakness that let spammers hijack domains tied to GoDaddy also affects a great many other major Internet service providers, and is actively being abused to launch phishing and malware attacks which leverage dormant Web site names currently owned and controlled by some of the world’s most trusted corporate names and brands.

773M Password ‘Megabreach’ is Years Old

January 17, 2019

My inbox and Twitter messages positively lit up today with people forwarding stories from Wired and other publications about a supposedly new trove of nearly 773 million unique email addresses and 21 million unique passwords that were posted to a hacking forum. A story in The Guardian breathlessly dubbed it “the largest collection ever of breached data found.” But in an interview with the apparent seller, KrebsOnSecurity learned that it is not even close to the largest gathering of stolen data, and that it is at least two to three years old.

Dirt-Cheap, Legit, Windows Software: Pick Two

January 8, 2019

Buying heavily discounted, popular software from second-hand sources online has always been something of an iffy security proposition. But purchasing steeply discounted licenses for cloud-based subscription products like recent versions of Microsoft Office can be an extremely risky transaction, mainly because you may not have full control over who has access to your data.
