According to TechFlow, regarding the incident in which a user had his crypto assets worth $1 million stolen due to a malicious plug-in, Justin Sun stated in the community that Poloniex exchange had also had $100 million stolen due to cookies.
Sun Yuchen suggested that apps involving funds should be kept logged out as much as possible to avoid using cookies online for a long time. In addition, services involving fund permissions should be set to automatically log out after a few minutes of non-use. Many banking software have begun to implement similar security measures.
