How does it infect the computer?

Worm:Win32/Mofksys!pz uses the autorun function on the infected computer so that it executes on its own when the drive is accessed. Then, it will spread the executable file together with the autorun.inf file into drives present on the infected PC. Other threats may also drop Worm:Win32/Mofksys!pz into the computer without the user’s knowledge by concealing itself from other programs.

Maliciously altered freeware, serial-generating programs, and crack software are also known sources used by attackers to deploy Worm:Win32/Mofksys!pz.

How does this malware operate?

Once Worm:Win32/Mofksys!pz infects a computer, it typically operates by executing its code and attempting to spread to other vulnerable computers on the same network or over the internet. Worm:Win32/Mofksys!pz often exploits security vulnerabilities or weaknesses in software to gain unauthorized access to target systems. Once inside a computer, it may replicate and distribute copies to other devices using various methods, such as email, instant messaging, or exploiting shared network resources. Additionally, worms may carry payloads that perform malicious actions, such as stealing sensitive information, corrupting files, or launching denial-of-service attacks. Worms can operate autonomously, continuously scanning for new targets and spreading rapidly, making them particularly challenging to contain and eliminate.

During the existence of Worm:Win32/Mofksys!pz, it tries to look for removable drives, network drives, and other shared resources where it can store itself. USB removable drives are the most exposed to Worm:Win32/Mofksys!pz, especially those that don’t have write protection features. Network-shared resources that are not protected may also be targeted by Worm:Win32/Mofksys!pz.


Once Worm:Win32/Mofksys!pz infects the computer, users might observe changes to their files or directories, including the creation of new files or modifications to existing ones, as worms may alter system settings or corrupt data as part of their payload. These noticeable signs can serve as red flags, indicating a possible Worm:Win32/Mofksys!pz infection and prompting users to take immediate action to eliminate the threat, such as running antivirus scans, disconnecting from the network, or seeking assistance from computer security professionals. Additionally, antivirus programs may also display alerts about the presence of Worm:Win32/Mofksys!pz.
