Stroman is another threat to your files

Image of Stroman ransomware virus

Stroman is a recently emerged ransomware-type cyber infection that encrypts various files on the targeted computer. Malware uses a sophisticated encryption algorithm and locks files with .stroman file extension. Then it drops data recovery instructions in readinfo.txt file.

According to the ransom note provided by Stroman ransomware, victims have to pay $500 in 72 hours; otherwise, the size of ransom will increase.Victims have to contact criminals and make sure that they have an actually working decryptor. Attackers offer to decrypt 1-2 files that are not bigger than 10 Mb for free.

Authors of the Stroman virus promise to contact them back and provide decryption software, key, and user instructions as soon as they receive the payment. However, researchers from Los Virus[1] warn that this deal might end up with money loss or blackmailing.[2] Thus, you should put data recovery to the second plan and focus on virus removal.

This crypto-malware is still under investigation. However, the recent data does not give much promising news about possibilities to recover files for free. However, there’s still a chance that third-party tools might help. Possibility to restore data might increase if Stroman does not delete Shadow Volume Copies of the targeted files.

After ransomware attack, we highly recommend scanning the system with Reimage or another powerful anti-malware in order to remove Stroman entirely. However, ransomware might be design to block installation or access to security tools. Thus, in this case, you should follow the instructions below and disable the virus first.

Keep in mind that manual Stroman removal is not recommended. It’s a complex malicious program that may have affected numerous legit system processes and installed malevolent files that look like safe files. Thus, you might leave dangerous entries or even delete crucial system files. Security tools help to avoid such mistakes.

Malware developers use multiple methods to launch cyber attacks

Stroman, as well as other file-encrypting viruses, spread using several strategies. The variety of used attacks allows infiltrating more devices and broaden the scale of the attack. However, the majority of ransomware is being spread using the same methods, such as:

  • malicious spam emails with infected attachments;
  • malware-laden ads;
  • exploit kits;
  • unprotected RDP connections;
  • fake downloads;
  • bogus software installers.

Malware payload might be dropped and immediately executed on the system when users open safely looking Word or PDF document. Thus, it's recommended not to open spam emails and attachments sent from unknown people.

Users should also be careful with installation of free programs and their updates. Avoiding file-sharing websites and using legit publishers’ sites is crucial to avoid accidental installation of a malicious app.

Additionally, keep all the programs updated and add another layer of security by installing an antivirus program.[3]

Terminate Stroman and try to restore files without paying for cybercriminals

Stroman removal must be completed using reputable malware removal tool because of ransomware’s operation features and ability to make system modifications. We recommend using Reimage or Malwarebytes Anti Malware, but you can choose your preferred tools as well.

If you cannot download, install or run security software, please reboot your PC to the Safe Mode with Networking as shown in the instructions below. Then you will be able to run automatic malware elimination.

Once you remove Stroman, you can use data backups and replace corrupted files with working ones. However, if you do not have them, you can find alternative methods and tools that MIGHT help to restore damaged data below.

  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Try ShadowExplorer

If Shadow Volume Copies were not deleted by malware, this tool might be helpful as well.
