How to remove Held Ransomware and decrypt .held files

What is Held Ransomware

Held Ransomware is a malicious software variant belonging to the STOP/Djvu ransomware family, known for targeting individuals and encrypting their files. This ransomware employs the Salsa20 encryption algorithm to lock files, rendering them inaccessible to the victim. Once it infects a system, it appends the .held extension to the encrypted files, signaling that they have been compromised. The encryption process involves scanning directories for files to encrypt, duplicating them, deleting the original files, and then encrypting the copies. This method is designed to prevent interference from open files due to Windows restrictions. After encryption, a ransom note is created, typically named _readme.txt, and placed in the same directory as the encrypted files. This note informs victims that their files have been encrypted and provides instructions for purchasing a decryption tool and unique key, often demanding a ransom between $499 and $999 in Bitcoin.

Unfortunately, decryption options for Held ransomware are limited. While there are no universal decryption tools specifically for Held ransomware, the Emsisoft STOP/Djvu Decryptor can sometimes assist in decrypting files infected by this ransomware family. However, successful decryption with this tool heavily depends on certain conditions, such as the use of an offline key during the encryption process. If an offline key was used, there is a possibility that the Emsisoft decryptor can recover some or all of the encrypted files. To attempt decryption, victims should download the decryptor, follow the instructions carefully, and run it on the affected files. It is crucial to note that paying the ransom is highly discouraged, as it does not guarantee file recovery and only fuels the ransomware economy. Instead, victims should explore alternative data recovery methods and ensure robust cybersecurity measures are in place to prevent future infections.

How Held Ransomware infects computers

Held Ransomware primarily infiltrates computers through deceptive distribution methods, including third-party downloaders, installers, and peer-to-peer networks. Users are often tricked into downloading malicious software disguised as legitimate applications or tools, such as keygens and cheat engines. These fraudulent downloads are commonly found on dubious websites that promise free access to paid software, serving as bait for unsuspecting users. Once downloaded, Held Ransomware leverages exploits in Remote Desktop Protocol (RDP) and other vulnerabilities to gain unauthorized access to the system. After gaining entry, it modifies system configurations, disables security features like Microsoft Defender, and begins its encryption process, locking files with the .held extension. This ransomware’s methodical approach to infection underscores the importance of exercising caution when downloading software and maintaining updated security measures.

7. How to protect from threats like Held Ransomware

Virus modifies “hosts” file to block Windows updates, downloading antivirus programs, and visiting sites related to security news or offering security solutions. Held Ransomware comes along with AZORult trojan, which was initially created to steal logins and passwords. The process of infection also looks like installing Windows updates, the malware shows a fake window, that mimics the update process.

It uses rdpclip.exe to replace a legal Windows file and to launch an attack on a computer network. After encrypting the files, the encrypter is deleted using the delself.bat command file. Held Ransomware virus is propagated via spam attack with malicious e-mail attachments and using manual PC hacking. Can be distributed by hacking through an unprotected RDP configuration, fraudulent downloads, exploits, web injections, fake updates, repackaged, and infected installers. The virus assigns a certain ID to the victims, which is used to name those files and supposedly to send a decryption key. Great tools to protect against Held Ransomware are: Emsisoft Anti-Malware and Malwarebytes Anti-Malware.
