China-based SMS phishing groups, known as the "Smishing Triad," are increasingly targeting customers of international financial institutions by converting stolen payment card data into mobile wallets. Utilizing innovative phishing techniques and a vast cybercrime infrastructure, these groups are bypassing traditional SMS methods by sending messages through iMessage and RCS, achieving high delivery rates and expanding their operations globally. Experts emphasize the need for financial institutions to adopt more secure methods for verifying card enrollments to combat this rising threat.
