Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.

Do you have any information that suggests that such attacks (guessing the password of a user) are

A constant-time algorithm should be used for checking the value of info. In other words, the comparison time should not depend on the content of the input, Otherwise, an attacker may be able to implement a timing attacks that may reveal the value of sensitive info
