Several phone numbers have been shared today on Twitter, apparently associated with support scammers. I haven’t checked them personally,.
@ has listed several numbers associated with the sort of fake alert pop-ups and related sites I described in Tech Support Scams: Top of the Pop-Ups. His list is here. He also has a list here of numbers associated with cold-calling scammers, and a more general article on support scams here.
@circl_lu added +47 64 74 78 57
@ (Xavier Mertens) apparently has some numbers on his diary, but I don’t have a link for that unless he’s referring to the Internet Storm Center diary, in which case you’d need to do some searching there, if you’re interested in more information.
Resource page updated accordingly.
