An attacker needs to embed a specially crafted deepchat: URL on any website, which could include a malicious one they control. When a victim visits this infected site or clicks on the malicious link, the browser triggers DeepChat&#8217;s custom URL handler (deepchat:), causing the DeepChat application to launch and process the URL.
