How dangerous is Samas ransomware virus?

Samas ransomware, alternatively known as Samas DR ransomware, has been attacking organisations and companies since 2014. Indeed, this file-encrypting virus is quite unique because it does not concentrate on targeting home computer users. Institutions and business enterprises have lots of important documents saved on the computers and networks. Hence, losing them to the virus might be a disaster. Hence, companies might be willing to pay demanded ransom. During its lifetime, Samas virus has already compromised thousands of important documents and swindled a huge amount of dollars. The majority of victims were companies working in health sector in North America and Europe. However, some law institutions and other public organisations experienced ransomware attack as well. Fortunately, lots of businesses are aware of the fact that data backups are crucial. In this case, they did not need to pay the ransom. According to the malware researchers, this crypto-malware has been updated many times, and now we can find around 60 variants of Samas malware. Though, all of them barely differs from each other and have the same goal – to make money illegally.

Hackers distribute ransomware using sophisticated methods; though, after infiltration, it either locks or encrypts targeted files. For data encryption, it uses RSA-2048 encryption algorithm and originally appends .encrypted.RSA file extension. However, other virus versions might append .theworldisyours, .whereisyourfiles, .iloveworld, .weareyourfriends, .whereisyourfiles, or .helpmeencedfile extensions. Sadly, Samas removal won’t rescue your files from hostage. However, hackers don’t leave victims without any suggestions too. The virus generates a ransom note and leaves it the affected computer’s desktop. In the ransom note it is clearly stated that victims need to purchase a specific decryption software to restore data. Nevertheless, information written in the PLEASE_READ_FOR_DECRYPT_FILES_{victim’s ID} file might seem the only option to get back the files; transferring demanded amount of Bitcoins is a risky business. Paying the ransom does not guarantee that hackers provide the necessary decryption key and software. The purpose of all ransomware projects is to swindle the money, and helping the victims is just the matter of conscience. It’s better to remove Samas from the computer rather than risk losing the money. After automatic virus elimination with malware removal tools such as Reimage or Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus, victims can try to restore files using alternative data recovery methods we have presented at the end of the article.

How does ransomware get inside the computers?

Samas ransomware virus employs traditional distribution strategies such as malicious spam emails and their attachments, or exploit kits. However, this successful cyber threat does not rely on spreading fake and infected invoices, statements or other ‘important’ documents that trick people to open attached file. Distribution methods are frequently updated and each version of the virus might use more polished and advanced techniques. The virus mostly employs brute-force attacks and tries to hack insecure networks. Samas uses reGeorg tunnelling tool which helps to find flaws and vulnerabilities in security. What is more, malware may also use data-stealing malware to hack targeted networks and drop virus executable directly to the compromised computer. It might seem that protecting computers and organisations from this ransomware is nearly impossible. However, it’s not true. No one can feel 100% safe and protected from ransomware but strengthening computer’s security with antivirus programs, keeping all software updates, and being careful with received emails can help to minimise the risk of attack.

What to do if Samas ransomware infected a computer?

Many people, who encountered ransomware, often think about ways to get back their files. No matter how important files are, the biggest problem is a virus residing on the computer. It’s important to remove Samas from the computer immediately because other computers connected to the same network might be at risk. What is more, malware may try to steal banking information or other sensitive data. Therefore, after the attack, you should choose one of the malware removal tools – Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware – and perform a full system scan. Do not think about manual Samas removal because you may cause damage to your computer. Bear in mind that you are dealing with hazardous and complicated cyber threat. Hence, it’s removal must be taken seriously and professionally.

Bonus: Restore your files

Using the tutorial provided above you should be able to eliminate Samas from the infected device. novirus.uk team has also prepared an in-depth data recovery guide which you will also find above.

If you still considering whether you should pay the ransom or not, we want to discourage you from doing this. Your money is a motivation and sponsorship for the cyber criminals. What is more, after receiving your Bitcoins, cyber criminals may disappear and forget their promises to restore your data.

There are a couple of methods you can apply to recover data encrypted by Samas:

Data Recovery Pro might help to restore files encrypted by Samas ransomware

Some of the files might be encrypted using Data Recovery Pro. This tool was originally created to restore damaged or deleted files; however, it also helps to rescue some of the encoded files as well.

  • Download Data Recovery Pro (https://novirus.uk/download/data-recovery-pro-setup.exe);
  • Install Data Recovery on your computer following the steps indicated in the software’s Setup;
  • Run the program to scan your device for the data encrypted by Samas ransomware;
  • Recover the data.

Files encrypted by Samas virus might be recovered using Windows Previous Versions feature

If System Restore function has been active on your PC before Samas attack, you should follow these steps to recover individual files:

  • Right-click on the encrypted document you want to recover;
  • Click “Properties” and navigate to “Previous versions” tab;
  • In the “Folder versions” section look for the available file copies. Choose the desired version and press “Restore”.

Samas decryptor

Unfortunately, Samas decryptor hasn’t been created yet. Hopefully, it will be released soon.

It is strongly recommended to take precautions and secure your computer from malware attacks. To protect your PC from Samas and other dangerous viruses, you should install and keep a powerful malware removal tool, for instance, Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware.
