FabSysCrypto (.Locked) Ransomware Removal and Decryption Help

FabSysCrypto ransomware belongs to the HiddenTear family of infections. It is a common crypto virus that drops the malicious file fabsyscrypto.exe on the system and executes it to start the encryption of important target data. For the enciphering purposes, FabSysCrypto implements the strong AES algorithm. Upon encryption, it appends the malicious extension .locked to all corrupted files. Then it drops a TXT file / called _HELP_instructions.txt/ that is designed to guide the victim in getting the private decryption key that is expected to restore the files.

This article aims to help all victims of FabSysCrypto ransomware by providing consistent removal guide. Even if you are not a victim of the threat, we advise you to meet the specifics of a ransomware infection in order to stay cyber safe in future and avoid getting malware.

Features of FabSysCrypto Ransomware

The infection process starts once the malicious file fabsyscrypto.exe is running on your system. What follows is a scan of the entire system that aims to find particular file types and encrypt them. Afterwards, all corrupted files get the malicious extension .locked and remain unusable until there is a decryption key to restore them. Currently the list of all file types targeted by FabSysCrypto ransomware counts 20 and includes:

.asp, .aspx, .csv, .doc, .docx, .html, .jpg, .mdb, .odt, .php, .png, .ppt, .pptx, .psd, .sln, .sql, .txt, .xls, .xlsx, .xml

All these files get encrypted via AES encryption algorithm and receive the extension .locked. Each file with appended .locked extension cannot be opened with any program until it is decrypted.

The extortionists urge victims to follow specific TOR and ONION links in a view to pay a ransom and receive the private key that is claimed to restore encrypted data. The links are included in the FabSysCrypto ransom note that is known under the name _HELP_instructions.txt. It depicts the following text:

All of your files are encrypted with RSA-2048 and AES-128 ciphers.
More Information about the RSA and AES can be found here:
Decrypting of your files Is only possible with the private key and decrypt program, which Is on our secret server.
To receive your private key follow one of the links:
1. xxxx://32kl2rwsjvqjeul7.tor2web.org/56D592DC7A9DDlDB
2. xxxx://32kl2rwsjvqjeul7.onion.to/56D592DC7A9DDlDB
3. xxxx://32kl2rwsjvqjeul7.onlon.cab/56D592DC7A9DDlDB
If all of this addresses are not available, follow these steps:

It is notable that the creators of FabSysCrypto are trying to mimic the ransom note of the infamous Locky ransomware. However, FabSysCrypto is based on the HiddenTear source code so the statement “All of your files are encrypted with RSA-2048 and AES-128 ciphers“ is not valid as HiddenTear is programmed to implement only AES encryption algorithm. Eventually, FabSysCrypto is less dangerous than Locky ransomware, and there is a chance that some third party tools might help you to recover some .locked files after the removal process.

The further impact caused by FabSysCrypto ransomware infection may be modifications of the Windows registry keys. The most common targeted locations are:

  • HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Run
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\RunOnce
  • HKEY_USERS\DEFAULT\Control Panel\Desktop

If FabSysCrypto creates value in Run folder, it will allow the ransomware to activate itself anytime the system is started. Changed values in the Desktop folder usually lead to the replacement of the current wallpaper with the ransom message file.

As regards the ransom amount we have found information that the crooks demand 0.5 BTC for the decryption tool and key. We want to remind you that any negotiations with cyber criminals are inadvisable.

Methods of FabSysCrypto Delivery

How can the executable application fabsyscrypto.exe land on your computer?

Among the most common ways of FabSysCrypto ransomware infection are:

  • Spam email campaigns – the message is most likely to urge you to download and interact with a ZIP archive or document attachment that contains the ransomware payloads. It could be hard to recognize the malicious intention of such emails as cyber criminals are good at impersonating legal services that we use in our everyday life. So we recommend thinking twice before a click and better refraining from opening attachments that look suspicious. One way to understand whether a file is malicious or not is to check it with online scanning services like ZipeZip and VirusTotal.
  • Malicious web links – such web links may be posted on e-mail messages with convincing notes to click them immediately or in spammed comments on sites that are not adequately secured against spam. Another method of spreading malicious URLs is on social media sites like Facebook and Twitter. The malware can be hidden in a fake notification, counterfeit shares from compromised accounts, spammed private messages, etc.
  • Freeware software – be careful when you decide to download and install free applications choose wisely the sources and if you find the wanted app on the official website of the vendor better download it from there. Sometimes the malicious ransomware payloads may be bundled with the freeware package so threats like FabSysCrypto may land on the system unnoticed.
