**Impact** Over 390 million scam attempts have been blocked on U Mobile’s ULTRA5G network since its inception, protecting Malaysian users across voice calls, SMS, and data channels. The surge in phone scams, which increased 46% year-on-year with 481 cases reported in January 2026, has resulted in RM27 million in financial losses, primarily affecting consumers engaging in banking, shopping, and healthcare services.

Mobile operators should implement SMS and voice call firewalls to intercept scam attempts and consider blocking SMS containing links to prevent redirection to fraudulent sites. Users should be educated about Scam Call Alert features and the risks of interacting with suspicious calls or messages. No patch or specific IOC information was provided for endpoint-level actions.
