Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group Shadowbyt3$ on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

Post text · scraped from the leak site

This is not a leak just an announcement that will stay up for however long they want to extend the promotion. Some may have been wondering why there is a logo of BreachForums. There is a logo because we have made an agreement with the BreachForums link. It seems legit and DragonForce has also done a promotion for them. Since DragonForce promoted them we decided to promote them. There have been many clones but if other groups are on there then it should be legit. We have loved BreachForums since when it first started and we would do anything to bring it back. We will promote them for one month starting today unless if they agree to extend the promotion. Check them out, register, and if were on there you should be on there. We will take a risk together but looking so far it's legit and the BreachForums clones is a long long story that It would take forever for us to explain.
