This often doesn’t happen we talk about the brot force Nice Thing in a computer space. Usually it is in reference to hackers in which money is demanded, or even worse, the game is for the original Xbox. This time the practice of bombing a system with digits that is expected to work for the right people, Akira Rensimware has been bursting through a lonely RTX 4090 in just seven days.
Tom’s hardware Tiny Hack saw this work, which is responsible for exploitation. The blogger has given details of the adventures that include helping a company restore data after the attack in forced ways. It is very incredible to see that such a work is done on a user, if a high graphics card.
Akira, as a name, can cover a range of renomware, and it is known for a while, but not all, forcibly sharing weakness. Avist’s research team was first looking for exploitation and posted a free tool around it in 2023. Of course, since then, these variations of Akira have been patching and updated, but the knowledge gained from fighting them is still useful.
The attack on this solution is using uncle 8 and Kcipher2 is using encryption methods. These are well -known ways, and here they are used to produce unique keys per file encryption. IT to try to make them as difficult as possible, it uses four separate time stamps in nano seconds, such as seeds.
The use of time stamps for Akira’s encryption is good and bad. On the one hand, this means that it is possible to determine this way only if the files are not changed and still there is a stamp of time. This server can also be hidden at intervals. So when you try to discontinue, we may not find the exact time stamp, but we may be quite close (on average (on average 5 million nano -seconds), then hand over the machines to the final brutal forced defeat.
Once again, only if we are so lucky that all these stars are aligned in the first place.
But I still think that the most interesting part of Tiny Hex’s exploitation is that it was all done on a RTX 4090 in just seven days to get keys. After that it took three more weeks to withdraw its full virtual machine to the client, but without paying the ransom. Adding more GPUs will be much faster. It is estimated that 16 of them will take only 10 hours with GPU. I wonder how the new RTX 50 series cards will be fair.
Tiny Hack’s Blog It has been deeply submerged on how this incredible recovery manages. This includes a link to the full code on the Gut Hub, as well as a link to the hash codes for another Akira Ransamware. Although it is worth remembering that it doesn’t always work, and you will still have to be very fortunate to recover your data after the attack, as Tiny Hack notes at the end.
“Perhaps 99.9 % of the time when you get a rinseware, it will not be recovered without a key. But if you are lucky, sometimes it is possible to find a solution.”
