Blackshadow ransomware group
Blackshadow 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 4y ago.
Who they are
BlackShadow is a state-aligned cybercrime group reportedly linked to Iran’s cyber operations, first identified in late 2020. Their operations blend data exfiltration with ransom threats, notably targeting Israeli organizations such as Cyberserve—a web hosting provider—and leaking data to inflict reputational damage. Victims included entities like Atraf (an LGBTQ dating app), tour booking services, and museums, reflecting political or ideological motivations over financial gain. Despite carrying out extortion, there is no evidence that BlackShadow employs typical encryption-based ransomware mechanics; instead, they leverage stolen data and the threat of public exposure.
Current status
Blackshadow'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 Blackshadow 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.
