Identity confidence

Medium

Independent sources exist, but identity continuity has not been independently confirmed.

  • Supports confidence: Independent sources: 3
  • Supports confidence: No unresolved identity conflicts
  • Supports confidence: Status history is consistent
  • Weakens confidence: Identity cannot be independently confirmed
  • Context: Never observed responding

Availability and identity are assessed separately. A responding endpoint does not show that it is operated by the entity it claims to be. Why this matters

What it is

grief is the name under which the open ransomwatch project catalogued a group that published, or claimed to publish, data taken from victims on a leak site. The project recorded one leak-site location for it.

The project links 2 published analyses of the group by security researchers; they are listed in the references and are the best starting point for what is actually known.

ransomwatch is archived, so this record is historical and says nothing about whether the group is active today. WikiHidden does not publish leak-site addresses, victim names or leaked material. Ransomware brand names are frequently reused, renamed and imitated, so a site using this name is not necessarily the group described here.

If you are affected

General guidance for organisations hit by ransomware or data extortion. It is not legal advice.

  • Isolate affected systems from the network, but do not switch them off: memory and logs are evidence.
  • Report it to the police and to your national cybersecurity agency or CERT. In many places, notifying the data-protection regulator is a legal duty with a short deadline.
  • Check whether a free decryption tool exists before considering anything else. No More Ransom: free decryption tools
  • Paying does not guarantee that data is restored or deleted, and in some jurisdictions payments to sanctioned groups are illegal.
  • Keep the ransom note, samples of encrypted files and all logs, and bring in incident-response specialists.

Impersonation and scam reports

Only reports confirmed by a reviewer are listed. A report describes lookalikes of this entity; it is not a statement about the entity itself.

No confirmed reports. That is an absence of reports, not a guarantee that no impersonators exist.

Evidence history

The most recent accepted observations. Each records whether something responded and, separately, whether identity was assessed.
