Ransomware Recovery

Onyx ransomware, first observed in April 2022, is a particularly destructive variant that not only encrypts files but also destroys them if they are larger than 2MB.

Unlike typical ransomware that encrypts files for ransom, Onyx overwrites larger files, creating a significant loss for the victims.
This behavior was initially suspected to be deliberate, but it appears more likely to be an accidental coding mishap.
Onyx targets files with specific extensions and encrypts those smaller than 2MB using AES+RSA algorithms, appending a .ampkcz extension.
If the files are larger, they are destroyed by randomly creating junk data. A ransom note "readme.txt" is dropped into every encrypted directory, and the ransomware operators offer to decrypt two random files for free as proof of their ability to restore the data.
The ransomware is distributed through tactics like social engineering, phishing, and malicious attachments. It employs a double-extortion approach, threatening to publish stolen data if the ransom is not paid.
Interestingly, Onyx is based on the Chaos ransomware builder and shares similarities with the Conti ransomware gang's ransom note logic.

Secure and Fast Diagnosis to Analyze Ransomware Types and Cryptographic Attack Vectors

Our experts decipher RSA and AES algorithms, used by Governments, ISPs, Technological, Financial and Telecommunications Industries.
RSA as an asymmetric encryption algorithm uses 2 keys: 1 public to encrypt, 1 private to decrypt. AES is a symmetric encryption algorithm with common key lengths of 128, 192, and 256 bits.
Digital Forensic Analysis
We carry out a complete diagnosis of the encrypted files and affected systems to identify patterns that allow data recovery.
Reverse Engineering
We analyze the encryption algorithms to unlock your files and quickly find weaknesses in the code of the computer virus to decrypt it.

What our customers say about us

Why Should You Never Pay The ransom?

In 2020, OFAC and FinCEN declared it illegal to pay a ransom:

Companies that facilitate ransomware payments, not only encourage future ransomware payment demands but also may risk violating OFAC regulations.

What should I do if Ransomware has Encrypted my data?

1. Turn off or disconnect the computer from the network

2. Do not ever make contact with the cybercriminals

3. Do not pay the ransom requested for your data

4. Contact us immediately and get help 24/7 worldwide
