Dutch Police are aggressively going after Dark Web vendors using data they collected from the recently seized Hansa Market. The infosec community and former Hansa vendors themselves have spotted two ways in which Dutch authorities are going after ex-Hansa vendors. Authorities have taken the passwords of vendors who have the same usernames on both the old Hansa and the Dream Market. If vendors reused passwords and they didn’t activate 2FA for their Dream Market accounts, authorities take over the profiles, change passwords, and lock the vendors out of their shops.
