TechFlow reports that in response to a user losing $1 million worth of cryptocurrency assets due to a malicious plugin, Justin Sun stated in a community discussion that Poloniex exchange had previously suffered a $100 million loss due to stolen cookies.
Justin Sun recommended that apps involving funds should remain logged out by default and avoid staying online for long periods using persistent cookies. Additionally, financial services should automatically log users out after just a few minutes of inactivity—similar security measures have already been adopted by many banking applications.
