Ryan Barnett, director of security research at Breach Security, said a security hole that had not been patched two years ago in Yahoo! accounts. Mail can help hackers attack and take control of the user's mailbox, according to The Register.
The vulnerability that Ryan Barnett has warned is also supported by other security experts. In addition, experts say that this is also one of the reasons why the network attacks in recent times happen more often!
Ryan Barnett's argument that Yahoo's account management Mail still many points are not safe. For example, when a user enters a Yahoo! account Mail and enter any password, then Yahoo Mail will tell the hacker that the account was just entered or that the password is real or not, this will help the hackers know where to attack.
While the password management mechanism is very loose, until now Yahoo Mail still allows users to use password types such as "123456", or "abcdef" ... although the probability is not high, but the hackers can still take advantage of this gap to break into the account of user.
