Vulnerability Management in Atypical Environments: ICS, Networks, IoT, Mobile, Hardware, and ML Systems

Vulnerability management follows the same core process across environments—identify assets, scan, assess risk, prioritize, remediate, and verify—but each domain introduces critical constraints. In industrial control systems, scanning must avoid disrupting physical processes, requiring audit-mode authenticated scans, digital twins for testing, and strict change windows. Network devices frequently suffer from poor segmentation, default SNMP community strings, and exposed management interfaces that enable traffic redirection or configuration tampering. IoT ecosystems remain plagued by default credentials, as demonstrated by the Mirai botnet that took down major DNS infrastructure in 2016, while modern botnets like Reaper and VPNFilter exploit unpatched firmware at massive scale. Machine learning systems face novel threats including prompt injection, prompt leaking, and jailbreaking that can bypass safety controls or exfiltrate training data. Mobile platforms suffer from extreme fragmentation that prevents timely patching of vulnerabilities such as Stagefright, Pegasus, and BlueBorne. Hardware-level flaws like Spectre, Meltdown, and BadUSB demonstrate that even firmware and silicon require coordinated microcode, OS, and application updates.

Pegasus Spyware Returns in Serbian Surveillance Campaign via Zero-Click iMessage Exploit

A Serbian student activist's iPhone was infected with the Pegasus spyware through a zero-click exploit in iMessage, allowing silent installation without any user interaction. The infection, confirmed by Citizen Lab in collaboration with the SHARE Foundation, showed indicators of compromise between December 2025 and January 2026. Apple later sent the target a notification warning of a mercenary spyware attack attempt. The exploit granted full access to photos, messages, files, and enabled covert microphone and camera activation. The vulnerability was addressed in the iOS 18.4.1 update released on April 16, 2025. The incident forms part of a wider surveillance wave in Serbia, with at least 14 individuals including students, activists, a parliament member, and a local political representative receiving similar Apple alerts. Additional targets were hit with Android spyware variants linked to NoviSpy.
