These are the worst passwords from the LinkedIn hack

A list of the worst passwords in the LinkedIn hack is remarkably familiar, but unremarkably depressing.

A list of the most popular passwords used by LinkedIn in 2012, at the time of the hack that recently came to light (again), was published by LeakedSource. The cache of 117 million accounts were hashed with the SHA-1 algorithm, a once-strong hashing system that was recently pushed into deprecation as it could be cracked.

But because the passwords weren't salted -- a process that makes it harder to decrypt.

It's estimated that about 90 percent of the passwords were decrypted -- a figure that will likely grow over time.

Last year -- which would've been two years after the LinkedIn breach -- the most popular password was, unsurprisingly, at the top of this list.
