BARCELONA, SPAIN | MARCH 3, 2026 — Today at MWC Barcelona, LATRO announced the official launch of Scammer Shield, a first-of-its-kind signaling overlay designed to neutralize "invisible" fraud threats that bypass traditional SMS firewalls.
As mobile network operators (MNOs) face an industrialized wave of SMS Blasters and Fake Base Stations—projected to contribute to a multi-trillion dollar cybercrime landscape—Scammer Shield provides the critical visibility required to protect both revenue and subscriber trust.
The Challenge: The Rise of "Invisible" Attacks
Traditional defenses rely on Content Filtering or CDR (Call Detail Record) analysis. However, modern fraudsters use rogue BTS (Base Transceiver Stations) to force devices onto legacy protocols, delivering malicious smishing payloads that never touch the operator’s core SMSC.
For the CTO and Head of RAFM, this creates a "blind spot" where attacks are executed without leaving a trace in standard logs.

The Solution: Intelligence Beyond the Firewall
LATRO’s Scammer Shield operates as a complementary signaling layer, utilizing LATRO’s patented Protocol Signature™ technology. Rather than inspecting message content—which often conflicts with evolving privacy regulations—Scammer Shield interrogates the signaling behavior of every device on the network.
- Real-Time Detection: Identifies rogue hardware and SIM Farms in milliseconds.
- Zero-Touch Integration: Deploys as a non-intrusive overlay, requiring no "rip and replace" of existing infrastructure.
- Protocol-Agnostic: Secures the network against 2G-fallback exploits and advanced 5G signaling threats.

Deep Dive: The Mobile Network Interview
During the launch at MWC, LATRO’s technical experts sat down with The Mobile Network Magazine to discuss the shift toward flexible, network-based approaches to scam detection. The interview covers the technical architecture of Scammer Shield and why signaling intelligence is the only way to outpace industrialized fraud.
