Linux Akira Ransomware: Brute-Force Decryptor Saves the Day (and Your Wallet)
Security researcher Yohanes Nugroho unveils a free GPU-based decryptor for Linux Akira ransomware. Using brute force, this tool cracks encryption keys through timestamp-based methods, freeing files without ransom payments. Initially a one-week project, it stretched to three weeks and $1,200 in GPU costs due to unforeseen complexities.
Hot Take:
Who knew GPUs could moonlight as ransomware decryptors? While gamers are busy saving virtual worlds, Yohanes Nugroho is out here saving real ones—one nanosecond at a time. It’s a bird! It’s a plane! No, it’s a cloud GPU service rescuing your files from the clutches of Akira ransomware! Who says you can’t have a superhero without a cape?
Key Points:
- Yohanes Nugroho engineered a GPU-based decryptor for Linux Akira ransomware, exploiting timestamp-based encryption weaknesses.
- The process took three weeks and cost $1,200, significantly longer and pricier than the initial one-week estimate.
- Akira ransomware uses four nanosecond-precision timestamps for key generation, complicating decryption efforts.
- By employing 16 RTX 4090 GPUs via cloud services, Nugroho managed to reduce the brute-forcing time to 10 hours.
- Nugroho published the decryptor’s source code on GitHub, making it accessible for others facing Akira ransomware.
