"These were accounts that had not reset their passwords since the 2012 breach. UPDATE: "We've finished our process of invalidating all accounts we believed were at risk," a LinkedIn spokeswoman told Tom's Guide in an email message.

Then set up two-factor authentication on LinkedIn and any other service than allows it.Īnd remember: Your password (or credit-card number) is only as safe as the company holding it in its database.
Write it down on a piece of paper, or, better yet, use a password manager. So, to reiterate: If you had a LinkedIn account in 2012, change the password now, and make the password something you CAN'T remember. In this light, "Rutabaga256!" isn't really that much better than "password."

"825,975 of the recovered passwords are 8+ characters and contain one upper, one lower, and one digit and one special character."Ī large chunk of those cracked complex passwords followed "universally common topologies," such as beginning with a capital letter followed by many lower-case letters, and ending with a digit or two and a punctuation mark. "5,184,351 of the recovered passwords are 8+ characters and contain one upper, one lower, and one digit," the KoreLogic researchers said in a blog posting. But we'll venture that many of the 188,380 people who had "password" as their LinkedIn password used it someplace else as well.ĭon't get smug, however, if your LinkedIn password met "strong" password recommendations.

Even though there are 177 million password hashes, there are so many duplicates that in total, there are only 65 million unique hashes. Security firm KoreLogic has already cracked nearly 80 percent of the hashes. A total of 165 million LinkedIn credentials were in the set - still with poorly hashed passwords - and this time, they included email addresses, letting anyone who got their hands on them hijack numerous accounts at other online services. Last week, the full LinkedIn dataset surfaced on an online-criminal forum, and it was far worse than anyone had feared. A year later, the company introduced an option to use to two-step verification. Following that revelation, LinkedIn said it reset the passwords for affected accounts, then implemented a stronger hashing algorithm.
The passwords had been "hashed," or scrambled with a one-way mathematical algorithm, in such a poor way that most of the hashes were swiftly "cracked" and the passwords revealed. Many of them included the text string "linkedin," making it clear where they came from. The quick back story: In June 2012, 6.5 million passwords, without accompanying email addresses, were found being sold in online criminal forums.

He'll tell you if your email address is in the data, and from which website it was stolen.
