Help_restoremydata ransomware group
Help_restoremydata is one of the extortion operations we watch continuously. This page covers what is known about the group and the current state of its leak site, which we last saw change 2y ago.
Who they are
Help_restoremydata is a ransomware variant identified around late 2024/early 2025, notable for appending the .help_restoremydata extension to encrypted files. It changes the victim’s desktop wallpaper and drops a ransom note titled HOW_TO_RECOVERY_FILES.html to instruct victims on how to pay for decryption. Initial discovery appears to stem from underground forum monitoring and threat intelligence assessments, marking it as emerging but not widely distributed. Technical details beyond these behaviors—such as encryption algorithms or distribution mechanisms—have not been documented in major cybersecurity advisories.

Current status
Help_restoremydata's leak site is not answering. Sites go dark for infrastructure trouble, a deliberate quiet period, or a takedown, and a good number return weeks later under the same name, so the entry stays on the list either way.
The last change we recorded on it was 2y ago (27 Jan 2025 18:05 UTC).
Which organisations this group has named, and when, is part of the SINON platform rather than this page. Create an account to search it, or to be told automatically if a name you care about turns up.
Sectors targeted
This group does not state an industry on its site, so we have nothing reliable to report. Most crews are opportunistic rather than sector-specific in any case — they hit what they can reach.
Watching for your name
If Help_restoremydata posts your company, a supplier or a subsidiary, you want to hear it from us rather than from a journalist. SINON checks these sites continuously and alerts on the names you give it.
