Christopher Sogoyan reported another security issue in the Dropbox cloud hosting service. He published the correspondence of one of the users with Dropbox support . That user wanted to log into his account and accidentally typed an extra character in the password field. Despite this, he logged into the account. Then he tried to log in with a random password from one letter - it worked out again. In the end, he also logged into the accounts of three of his friends, using passwords like 'q' and 'z', while he had access to all of their files.
The support service explained that this is a minor glitch that will be quickly corrected and will not happen again ( there was no problem ).
UPD. According to the official comment of Dropbox, the breach in the protection of accounts arose on June 20 at 0:54 Moscow time and was closed at 4:46 Moscow time. Less than one percent of users had a problem.
