Russian snoops add OAuth abuse to targeted phishing campaigns
Russian threat actors are incorporating OAuth abuse tactics into their targeted phishing campaigns, leveraging legitimate authentication mechanisms to compromise victims. The attacks specifically impersonate State Department communications, making them particularly credible to government and diplomatic personnel.
Researchers have identified iAuthFlow V2, a phishing toolkit that exploits passkey authentication by registering attacker-controlled passkeys to maintain persistent access to compromised accounts. This capability allows attackers to retain access even after victims reset their passwords or revoke active sessions, representing a significant evolution in phishing attack sophistication that targets modern authentication mechanisms.
Researchers at Allure Security discovered a widespread scam operation leveraging a cheap website template to create hundreds of fraudulent bank domains designed to deceive victims. The investigation began when a suspicious domain mimicking a legitimate financial services client was found hosting an unrelated bank's branding, ultimately revealing a coordinated scheme to build phantom banking sites for scamming purposes. The $25 template appears to have been a key tool enabling scammers to rapidly deploy deceptive financial websites at scale.
