Another kind reminder

We have in the past repeatedly warned thatfree things on the internet do not always come cost free. And today, wehave to make a kind reminder as we came across a new example.

Security Response received a file with a .tgz file extension, whichexploits a new unknown vulnerability in a free Japanese decompress tool"Lhaz v1.33". The file is detected as Trojan.Lazdropper.

After a successful exploit attempt, Trojan.Lazdropper drops two files, both detected as Backdoor.Trojan,onto the infected computer. As Backdoor.Trojan opens a back door tocommunicate with the author for further actions, it is obvious thatpurpose behind Trojan.Lazdropper is to take a complete control over theinfected machine.

As always, we recommend that you keep your security software up-to-date and follow safe computing practices.

We cannot stress this enough; if you receive any unexpected files, do not open them.
