Visitors of Ashley Madison, a recently hacked site where married people look for affairs, could become victims of blackmail.
A total of 37 million users, including some 1.2 million Britons, could be blackmailed by either The Impact Team, a group of hackers that recently stole private information from Ashley Madison's users, or whoever that group sells the information to.
Security experts believe blackmail could be the case because the majority of the information stolen is still kept secret.
Will Gragido, head of threat intelligence research at Digital Shadows, said that this particular hacking appears to be “extortion-focused”, Telegraph writes in a report.
He said that in a previous hack of Adult Friend Finder, a website for swingers, “data was evident in underground cybercrime forums relatively soon.
“We see comparatively little Ashley Madison data in circulation, suggesting the attackers want to hold as much as they can for ransom.”
A group which goes by the name The Impact Team, recently hacked into Ashley Madison and stole data from its 37 million users, including full names and addresses. The group says it has done so because the site lies about the “hard delete” feature.
Ashley Madison offers a full delete of a user’s profile for a fee of $19 in the US, and £15 in the UK, and has denied these accusations. It also offered this feature for free, following the breach.
A hacking insider named 'Vinnie' told Sky News said he thought the hackers would not release the data as promised in threats, but sell it on the deep web to other criminals.
"They’ll profit from this in a big way, especially with the size of this database."
