Gomer ransomware is a file locking virus belonging to the Outsider crypto-malware family and was first spotted by security researcher dnwls0719 in late June 2020.[1] Once inside the system, it encrypts all the pictures, videos, music, MS Office, PDF, and other files with the help of the RSA encryption algorithm.[2] As a result, victims are unable to access any of the personal data located on the PC. Besides, all the files are marked with .gomer extension and are missing their original icons.

Another sign of the Gomer virus infection comes right after that – a text file called GOMER-README.txt is dropped on users’ desktop. This ransom note explains what happened to the hosts’ files and that, allegedly, the only way to recover them is by paying an unknown amount of ransom in Bitcoin for the Gomer ransomware decryption key. However, victims should not contact cybercriminals via the provided [email protected] email, as they might never receive the promised tool.

It is yet not completely known how Gomer ransomware is spread, although cybercriminals typically use multiple attack vectors, including:

  • Spam email attachments and hyperlinks
  • Exploit kits and software vulnerabilities
  • Software cracks and pirated program installers
  • Unprotected Remote Desktop (RDP) connections
  • Malicious advertisements, etc.

Regardless of how the virus accessed your machine, however, the result always remains the same – your data gets encrypted. However, you should not panic and first focus on Gomer ransomware removal that should be achieved with the help of powerful security software, such as SpyHunter 5Combo Cleaner or Malwarebytes.

The contents of the ransom note are as follows:

There are several claims that the malicious actors behind the Gomer file virus are trying to make. For example, they are the only ones who can restore the encrypted data, although it is not true. They also offer a free decryption service for one file. All these promises are made for victims not to doubt the integrity of these statements and pay the ransom.

It is yet unknown what is is the amount that the attackers are asking for, although the payment is meant to be performed with the help of Bitcoin cryptocurrency. This is the most preferred method that ransomware developers use, as it allows them to stay anonymous when retrieving the money. In previous versions of Gomer ransomware, threat actors were asking for 600 Euro, although this can vary from victim to victim.

Regardless, security researchers from dieviren.de[3] do not recommend contacting cybercriminals, as they might simply never send you the promised Gomer ransomware decryption tool, and you will end up losing your money for good.

Instead, you should rely on alternative data recovery solutions – there are several options available, as we explain in the recovery section below. However, you should first remove Gomer ransomware from the system, and only then try to restore your files.

For that, you should employ powerful security software and perform a full system scan. You should note that removing the virus will not allow you to open .gomer files, as data encryption and malware infection processes are separate. Thus, do not expect that the anti-malware program will restore your files to the way they were prior to the infection.

However, you should also take care of your Windows computer after the Gomer ransomware is terminated. To remediate your machine post-infection of malware, we advise using Reimage Reimage Cleaner Intego repair tool.

Ransomware infection methods and prevention steps

As mentioned above, there are several ways how you could have got your computer infected with ransomware, as cybercriminals commonly use several different techniques in order to affect a broader spectrum of victims. Nonetheless, some strains, such as Djvu, have seen immense success by only using software cracks for the delivery. However, you should equip your computer with comprehensive security solutions and apply adequate measures to prevent ransomware infections in the future.

Once the infection spreads on the PC, files immediately get encrypted. Even if the malware is removed, the encrypted data cannot be opened – this is the main trait that results in such devastating consequences for users, as they might lose their precious photos, school work, and much more.

To protect your machine from ransomware attacks, follow these steps:

  • Employ powerful security software and keep it updated;
  • Enable Firewall and use ad-block;
  • Always patch Windows and the installed software with the latest security updates;
  • Protect all your accounts with secure alphanumeric passwords;
  • Never download software cracks or pirated program installers.

While many ransomware viruses delete themselves as soon as they finish the encryption process, some leftovers may remain. Additionally, it can also come along with other infections, so it is important to make sure that Gomer ransomware removal is performed properly.

Contact CERT Polska for free .gomer file recovery

Write an email at [email protected] and attach ransom note (GOMER-README.txt) along with a few encrypted files.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Gomer and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can’t grant a full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. 

Nevertheless, there’s a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

While much of the data can be accidentally deleted due to various circumstances, malware is also one of the main culprits that can cause loss of pictures, documents, videos, and other important files. Potentially unwanted programs may clear files that keep the application from running smoothly.

More serious malware infections lead to significant data loss when your documents, system files, or images get locked. Ransomware is the one that is focused on such functions, so your device gets useless without access to needed data. Even though there is little to no possibility to recover after file-locking threats, some applications have features for such 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.
