Deep dives
Abuse of Google OAuth in Phishing Attacks
A recent phishing attack exploited Google OAuth to perpetrate a DKIM replay attack, where the sender posed as a legitimate Google source. The attacker registered a domain and created a Google account, using a convincing email that passed DKIM checks, which ensured it reached the intended inbox undetected. This example highlights the vulnerability in email authentication methods, which can be manipulated to bypass security filters. Similar tactics had previously been observed in attacks aimed at PayPal accounts, underscoring the ongoing risks associated with email phishing schemes.
