Background for this topic.
Mobile security covers the protection of smartphones, tablets, and closely related handheld devices, including their operating systems, applications, wireless connections, and stored data. These devices combine personal and business information with cellular, Wi‑Fi, Bluetooth, and location services, and often provide access to cloud and corporate systems.
Material risks include malicious or over-privileged applications, phishing and fraudulent authentication prompts, unpatched operating-system or baseband vulnerabilities, and exposure after a device is lost or stolen. Security teams typically reduce these risks through timely updates, approved application sources, encryption, strong screen locks and phishing-resistant authentication where supported, and mobile-device management that enforces policy and can remove access or wipe business data. Application permissions and device telemetry also require privacy controls, particularly when personal and corporate data share the same device. Mobile vulnerability disclosures and incidents may require checking device models, operating-system versions, applications, and management coverage rather than treating all mobile devices as equivalent.

When chained together, the two vulnerabilities allow threat actors to gain root-level capabilities on SonicWall's mobile access appliances.
In hard-to-detect attacks, hackers are dropping the CloudZ RAT and a fresh plug-in, Pheno, to hijack the Windows-based bridge between PCs and smartphones.

The April/May zero-day exploitations of Ivanti's mobile device management platform meant unprecedented pwning of thousands of orgs by a Chinese APT — and history will probably repeat itself.
Iran's top state-sponsored APT is usually rather crass. But in a recent spate of attacks, it tried out some interesting evasion tactics, including delving into Snake, an old-school mobile game.
People habitually ignore cybersecurity on their phones. Instead of compensating for that, organizations are falling into the very same trap, even though available security options could cut smishing success and breaches in half.
With SMS, voice, and QR-code phishing incidents on the rise, it's time to take a closer look at securing the mobile user.
New features to take over smartphones and monitor user activity demonstrate the continued evolution of the malware, which is now being spread on GitHub.
