sms botnet 2024

SMS Botnet 2024 represents a sophisticated evolution of mobile malware that transforms infected Android devices into a network of remotely controlled bots. These botnets primarily exploit SMS capabilities to conduct large-scale spam campaigns, phishing attacks, and premium-rate fraud, while also serving as a gateway for more severe payloads like banking trojans. With improved evasion techniques and decentralized C2 infrastructure, modern SMS botnets pose significant challenges for mobile security professionals and telecom providers alike.

What is SMS Botnet 2024?

An SMS botnet is a network of compromised mobile devices controlled through covert SMS/MMS communications or alternative C2 channels (HTTP, Firebase). The 2024 variants demonstrate:

Advanced polymorphism to evade store screening
Zero-click infection via RCS messaging
Blockchain-based C2 for resilience
Dual-use functionality (spam + data exfiltration)
