Held Ransomware: Detection, Removal, and Prevention

Held ransomware, a member of the infamous Djvu family, is a malicious program designed to encrypt victims’ files and demand ransom payments in exchange for decryption tools. Discovered through malware samples submitted to VirusTotal, Held ransomware uses the “.held” extension to mark its encrypted files. This guide provides a detailed overview of Held ransomware, its functionality, and a step-by-step method to remove it using SpyHunter. Additionally, we will discuss preventive measures to avoid future infections.

What is Held Ransomware?

Held ransomware targets essential files like documents, databases, and images. Once it encrypts these files, it appends the “.held” extension, rendering them inaccessible. For example, “document.docx” becomes “document.docx.held.” It then generates a ransom note titled “_readme.txt,” instructing victims to contact the attackers via provided email addresses and pay a ransom to recover their files.

Key Characteristics of Held Ransomware

• Encrypted Files Extension: .held
• Ransom Note: _readme.txt
• Ransom Amount: $999 (with a $499 discount if paid within 72 hours).
• Contact Emails: support@freshingmail.top, support@yourbestemail.top
• Detection Names: Includes “Win32:CrypterX-gen [Trj]” (Avast) and “A Variant Of Win32/Kryptik.HYNI” (ESET-NOD32).

How Held Ransomware Works

Held ransomware employs advanced techniques to evade detection and encrypt files stealthily:

1. Dynamic API Resolution: It dynamically resolves API functions to avoid triggering security alerts.
2. Process Hollowing: The malware injects its code into legitimate-looking processes to mask its malicious activities.
3. Encryption: Using strong encryption algorithms, it locks files and prevents access.
4. Ransom Note Delivery: The _readme.txt file informs victims about the ransom demand and recovery options.

The ransom note emphasizes that recovery without payment is impossible, urging victims to act quickly to receive the discounted rate.

Distribution Methods

Held ransomware primarily spreads through:

• Untrustworthy Websites: Fake sites offering video downloads or cracked software.
• Malicious Email Attachments: Emails with macros embedded in attachments.
• Pirated Software: Torrents, key generators, and crack tools often carry ransomware.
• Malicious Advertisements: Ads redirect users to compromised sites.
• Technical Support Scams: Fraudulent support websites trick users into downloading malware.
