ransomwareW32.Mydoom.E is a dangerous worm that may open a backdoor to the affected PC and download and execute malicious files, making it completely defenseless. It is a variant of the infamous W32.Mydoom worm family. The worm may open several TCP ports so that it allows the attacker sending it out to connect to the computer directly and hence gain full access to the PC and the local network it is in. The worm is also believed to perform DDoS (Denial Of Service) type of attacks in scheduled times, depending on the attackers.

W32.Mydoom.E – How Did I Get Infected?

Mydoom malware is being distributed mostly via spam email attacks. The spam mails are being distributed to both users as well as domains. According to researchers the spam mails associated with this worm may contain the following as their subjects:

→”Test;hi;hello;Mail Delivery System;Mail Transaction Failed;Server Report;Status;Error”

More to it than that the spam mail may contain different attachements, usually with a .txt document’s Windows icon on them and their file formats are believed to be one of the following:

→.bat, .cmd, .exe, .pif, .scr, or .zip

Also, researchers report that this particular worm could send out spoofed emails that resemble something or someone important or already familiar to the end user.
Here are some of the attachment names associated with this family of worms:

→”document; readme; doc ;text ;file ;data ;test ;message; body

As it is to the attached files, they may be one or more files of the following formats:”

→.htm; .txt ;.doc ;.pif ;.scr ;.exe ;.cmd ;.bat; .zip

W32.Mydoom.E – What can it Cause?

Once started running in the background undetected, the worm may begin to create .dll and .exe files in %System% %Temp% and %AppData% that contain scripts. These scripts may modify different settings, such as disabling firewall and opening several ports of the computer in order to enable the backdoor to download and run different external files.
It may also run active executable processes that contain the same names as some original Windows Processes, such as tasking.exe or svchost.exe.

However, the worm may not execute the files by its own. This is why it may ad various registry keys or values in HKEY_CLASSES_ROOT in order to make Windows Explorer to load the malicious files without any hic ups. It may also situate registry values to run commands on system startup in:

HKEY_CURRENT_USER\Software\Microsft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

Once it has executed it’s hazardous .exe material the worm then commands it to open several ports without the user’s consent. It can then download anything onto the infected PC. We are talking about Rootkits, Trojans, Spambots, Crypters to remain undetected on the PC for long periods of time and ofcourse Ransomware Trojans. Ransomware, such as CryptoWall 3.0 is the sole reason for over 18 million dollars lost last year in online extortion. What the viruses do is encrypt user data with strong encryption in order to extort users using deadlines for payment in return for the decryption keys.

What is more this family of Worms is famous for denial-of-service type attacks otherwise known as DDoS. In case you notice your date changed to another one there is a good chance you may soon become a victim of one.
