A ransomware group calling itself Akira claims to have targeted BYK Construction, according to a listing on the group’s own leak site dated September 1, 2026. This claim comes from the group’s self-published extortion listing, which was tracked by ransomware.live, a security research platform that monitors ransomware groups’ public leak sites. BYK Construction has not confirmed this incident, and no regulator has verified the claim. At this stage, it should be treated strictly as an unverified assertion made by a criminal group seeking attention or leverage.
