What is Lsass.exe?

The Lsass.exe process is the Local Security Authentication Server, and is responsible for enforcing security policies in the OS. As such, this process is quite important. There have, however been cases where lsass.exe was used for malicious means. One of  these is the use of lsass.exe as an executable for a trojan, the other is the promotion of rogue anti-spyware programs, namely eKerberos.

The rogue displays the following fake warning:

Caution! Break-through attempt!

Process Isass.exe (1076) trying to get access to credit card information. What the risk?

Should the user choose to “deny” access to lsass.exe, he will be taken to the purchase page of eKerberos, where he will be urged to pay for the fake program.

Do NOT trust this alert, and remove eKerberos as soon as possible.
