Attacker assertion only. Establishes: claim date, group, alleged victim.
Unlocks: incident narrative, operational impact. Still no compliance clock.
Unlocks: discovery date, data types, affected count, compliance clock.
Unlocks: materiality, stated response, full audit trail. Ceiling removed.
No regulatory filing corroborates this yet — it is the attacker's own assertion. Watch this entity to be notified the moment a filing corroborates or contradicts it.

8base
According to ransomware.live, The 8base Ransomware group made its first appearance in early March 2022, remaining somewhat quiet after the attacks. This group operates like other ransomware actors, engaging in double extortion. However, in mid-May and June 2023, the ransomware operation saw a spike in activity against organizations from various sectors, listing 131 organizations in just 3 months. The 8base data leak site was created and made available in March 2023, claiming honesty and simplicity in its discourse. VMware published a report on 8base, drawing some similarities with the ransomware group `RansomHouse`, pointing out resemblances such as the website used by 8base and the ransom notes presented in its attacks. Interestingly, the 8base Ransomware group does not have its own ransomware developed by the group. Instead, the actors took advantage of other leaked ransomware builders to customize the ransom note and present it to the victim organization as 8base's operation.
