The executable is actually a publicly available wiper script (credits to a GitHub repo from 2019) wrapped in a Crypter. It doesn't encrypt files to decrypt them later; it simply renames them with a .hydra extension and deletes the originals after 72 hours. If you pay the Bitcoin ransom, hydra_rus has no technical way to get your files back. They are relying on the victim panicking before checking the code. Using a public blockchain explorer, we tracked the primary Bitcoin wallet advertised by hydra_rus (starting with 1Hydra... ). Over six months, the wallet received approximately $48,000 USD across 12 transactions.
At first glance, the name suggests a connection to the now-defunct Hydra Market (the Russian darknet giant seized by German authorities in 2022) and a geographic nod to the Russian Federation (the _rus suffix). However, as we dug through leaked databases, forum archives, and blockchain ledgers, a more complex picture emerged. hydra_rus did not appear out of thin air. By cross-referencing password reuse and writing styles on a prominent English-speaking hacking forum, we traced this account back to a previously banned user known as Volga_DM (2020–2021). After a dispute involving a stolen RDP (Remote Desktop Protocol) access log, Volga_DM vanished—only to re-emerge three months later as hydra_rus . hydra_rus
Medium (Low technical skill, High social manipulation). The Recommendation: If you receive an email from hydra_rus , do not pay. The files cannot be recovered via payment, and engaging with them will mark you as a target for future scams. The executable is actually a publicly available wiper
