// THREAT ACTOR
BERT_
DormantBERT is a ransomware operator tracked through its public data-leak infrastructure. The group operates under the double-extortion model that defines the modern ransomware ecosystem — file encryption combined with the threat of stolen-data publication on a public leak site — and continues to post fresh victim claims as part of an ongoing extortion campaign.
