3301 virus Removal Guide

What is 3301 ransomware virus?

New variant of Karmen emerges as 3301 ransomware virus

3301 ransomware virus

3301 ransomware is a virus that encodes files with AES-256 to make them inaccessible for the victim. The malware comes from Karmen ransomware family[1]. During data encryption, the virus appends .3301 file extensions to encoded files and creates DECRYPT_MY_FILES.html file, which is the ransom note.

The ransom note leads to an HTML page that says “You Are Locked by 3301.” The ransomware suggests that the victim has 168 hours or 7 days to pay the ransom and get data decryption key. Otherwise, the victim may lose the files forever because scammers will delete the decryption key from their servers after a week.

This virtual extortion tool is an illegal cyber weapon used to swindle money from inattentive computer users. Clearly, 3301 removal is the first thing that you need to do after noticing it in your computer.

The virus commands the victim to get Tor browser in order to access a particular website. Below, there are shortened versions of the ransom note available in 7 different languages. All of them suggest open an ID.TXT file saved on the desktop – it contains victim’s ID which is required in order for cyber criminals to recognize the victim.

After entering one of the payment websites, the victim has to choose a language and enter one’s personal ID in order to see the ransom demand. The virus asks buying Bitcoins and sending required amount to the criminals’ Bitcoin wallet. The payment website promises to automatically display the key as soon as the ransom is paid.

Sadly, it is unknown whether 3301 virus’ developers are trustworthy or not. Besides, paying the ransom means helping cyber criminals and funding their projects, which is not a good idea. We hope that you have a data backup and can recover your files for free.

If you don’t, please try the suggested data recovery methods first. Before you do so, make sure you remove 3301 ransomware. Use ReimageIntego software for it.

Distribution of Karmen 3001 ransomware version

Karmen RaaS[2] is known to be promoted via hacking forums, so it is quite clear how the 3301 version was created. To distribute this virus, its authors use typical malware promotion methods and tools, such as:

  • Trojans;
  • Illegal software;
  • Exploit kits;
  • Spam;
  • Malvertising.

All of these methods have been used by ransomware developers for years, but people are still struggling to keep ransomware viruses away from their computers. The best way to protect yourself is to install good anti-malware product and create a data backup.

Finally, DieViren.de[3] says that it is important to enable automatic software updates – it prevents hackers from exploiting vulnerabilities in outdated software. What is more, you should always install the latest Windows updates. One of such vulnerabilities allowed WannaCry ransomware to spread so quickly.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
