![]() When using the SHA1 method, without adding the salt, the plain text password of “1234” will always create the same hash, meaning “1234” will always hash to the following SHA1 hash value: If the hash does not match, the user will not be able to gain access. If the hashes match, the user is allowed access. When a user logs into their account by entering their text password “1234,” the hash of the password is checked against the stored hash of the password. Therefore, the password should never be stored in the database as plain text, but rather as a stored hash. One method is called Secure Hash Algorithm 1 (SHA1) (which is what LinkedIn had reportedly been using at the time of the 2012 hack) where a plain text password runs through a mathematical cryptographic algorithm that turns and stores the text password (“1234”) into a set of numbers and letters that look like this: Hashing is a mathematical algorithm that takes a plain text password and turns it into a set of letters and numbers. The password “1234” is then hashed and stored in the system. When a user first creates an account, they enter a password in plain text, such as “1234”. Because there are so many ways to crack passwords, including guessing (typically by using social media to figure out birthdays, pets’ names, favorite sports teams, etc.), dictionary attacks, and the use of rainbow tables (which we’ll go into later), it is more vital than ever to employ unique salted password hashing, which is in compliance with current cybersecurity industry standards.įirst, let’s understand how this all works. When creating a site that collects and stores user accounts, it is critical to ensure that passwords are properly protected. You may be asking yourself-what on earth are hashing and salting and how does this all work? However, if you have not changed your password since 2012, you do not have the added protection of a salted password hash. LinkedIn stated that after the initial 2012 breach, they added enhanced protection, most likely adding the “salt” functionality to their passwords. However, on May 16, 2016, 117 million LinkedIn accounts-reportedly from the 2012 hack-were found to be up for sale on a hacker site. LinkedIn sent a request to known hacked users advising them to change their passwords. Several other subsequent lawsuits were eventually consolidated.LinkedIn was breached in 2012 with a reported 6.5 million user accounts compromised. The original lawsuit, filed in June 2012, claimed LinkedIn failed to adequately encrypt passwords and other personally identifiable information (see: Member Sues LinkedIn for $5 Million over Hack). If any settlement funds remain after class members receive their claims, the money will be divided among the Center for Democracy & Technology World Privacy Forum and Carnegie Mellon CyLab Usable Privacy and Security Laboratory. "LinkedIn has agreed to this settlement to avoid the distraction and expense of ongoing litigation," the social network says in a statement provided to Information Security Media Group. The settlement also requires LinkedIn to implement data security protocols utilizing the industry standard encryption methods of salting and hashing for at least five years. District Court for the Northern District of California on Aug. ![]() "That amount is at least equal to, and likely surpasses, the amount that the individual LinkedIn subscribers could expect to receive at trial," according to the settlement, which was submitted in the U.S. Each individual will receive a share of up to $50. who paid a fee to LinkedIn for a premium subscription between March 15, 2006, and June 7, 2012, according to the settlement. ![]() ![]() The social network has agreed to pay a total of $1.25 million to breach victims in the U.S. The settlement still has to win court approval before it becomes final.
