The Akira ransomware has attacked numerous companies worldwide, encrypting their data and extorting large amounts of ransom. Now, an Indonesian programmer has written a tool that cracked the encryption in 10 hours. It uses graphics cards with Nvidia CPUs.

There was already a GPU-based decryptor on GitHub specifically designed to recover encrypted files. This tool leverages the computing power of GPUs to significantly accelerate the decryption process. It offers a way to help affected users without having to comply with the attackers' demands.

New decryption tool for Akira ransomware

Secondly, an Indonesian programmer named Yohanes Nugroho has developed another decryption tool that can crack the Akira ransomware in just ten hours. Bleeping ComputerA friend had asked him for help decrypting his Linux system, which had been infected by Akira. Nugroho analyzed the attack log files and discovered that Akira uses nanosecond timestamps to generate unique keys. By narrowing down the possible keys and using brute force, he was able to successfully overcome the encryption. His tool relies on the power of GPUs, such as the Nvidia RTX 3060, to perform millions of encryption tests per second. He rented the power of 16 Nvidia GPUs for the decryption, requiring a week of time and just over $1.

Both tools and approaches demonstrate how innovative technologies and individual initiative can help undermine the activities of cybercriminals. At the same time, they demonstrate the importance of precautionary measures such as regular backups and security software to protect against such attacks. These developments mark an important step in the fight against the growing threat of ransomware.
