Kraken Exchange said they have frozen Kraken account acess to certain funds they suspect to be associated with ''fraud, negligence or misconduct" related to FTX. And they will resolve each account on a case-by-case basis.

Earlier before the announcement, Nick Percoco, the CSO of Kraken Exchange, tweeted that the Kraken team now knows the identity of the user that hacked FTX.

Founder and CEO of IBCgroup.io, Mario Nawfal tweeted explaining that “the hacker is very likely an inexperienced insider.”
