Weaponized OAuth Redirection Leverages Browsers for Malware Delivery

• Attackers are weaponizing OAuth redirection logic to deliver malware, leveraging legitimate authentication flows to bypass traditional security controls.
• This sophisticated technique often tricks users into authorizing malicious OAuth applications or redirects them through compromised services directly to malware downloads within the browser.
• Users are advised to exercise extreme caution when authorizing third-party applications, and administrators should rigorously monitor OAuth application permissions to mitigate this browser-based attack vector.
