The instigator of the attack was apparently a hacker known as a “pompompurin”, who previously claimed responsibility for the hacking of FBI emails in 2021, where the FBI’s external email system was used to sending thousands of emails warning of a fake cyberattack.

Pompompurin also claimed responsibility for the 2021 attack on trading platform Robinhood, which was another case of large-scale identity theft.

Pompompurin attributed the vulnerability to an elastic search database that used weak credentials, meaning the blame can be placed on poor password hygiene, rather than software failures. antivirus or firewall.

Mangatoon users can search their email in the HIBP database to see if they have been affected, but should seek to change their passwords immediately to ensure their security.

But it’s not just Mangatoon that has been letting data fall into the hands of cybercriminals in recent months.
