Balletspistol ransomware group
Balletspistol 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.
Who they are
BalletsPistol is a Python-based ransomware strain distributed via GitHub. An investigative report from June 2025 reveals its delivery through a malicious ISO file hosted on a now‑removed public GitHub repository

. The infection chain begins when the ISO (named Invoice.iso) is downloaded and mounted, revealing a batch script (MAIN.BAT) and supporting components—including a password-protected ZIP and shortcut (.lnk) for execution. The malware performs privilege escalation (via UAC bypass using fodhelper.exe), persistence via registry and scheduled tasks, and then extracts an executable from the ZIP to commence the main payload. This binary encrypts user files with a hybrid AES + RSA scheme, adding the .iDCVObno extension to encrypted files; it also drops ransom notes (RESTORE-MY-FILES.TXT or .HTA) and changes the victim’s wallpaper.
Current status
Balletspistol'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.
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 Balletspistol 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.
