CompTIA A+ Core 2 (220-1202)SecurityMedium
A user reports that their mobile phone is behaving erratically: apps are crashing frequently, the battery drains much faster than usual, and there are strange pop-ups appearing even when the browser is closed. The user also notices unfamiliar apps installed that they don't recall downloading. What type of security threat is MOST likely affecting the mobile device?
- APhishing
- BMan-in-the-Middle (MITM)
- CDenial of Service (DoS)
- DMobile Malware
Show answer & explanationAnswer & explanation
Correct answer: D. Mobile Malware
The symptoms—erratic app behavior, rapid battery drain, strange pop-ups, and unfamiliar installed apps—are classic indicators of mobile malware, which can include various types like adware, spyware, or Trojans specifically targeting mobile operating systems.
Why the other options are wrong
- A. Phishing is a social engineering attack, not a direct infection causing these system-level symptoms.
- B. MITM attacks intercept communication but don't typically cause app crashes, battery drain, or unexpected app installations.
- C. DoS attacks aim to make a service unavailable and wouldn't manifest as installed apps or strange pop-ups on the device itself.
Mobile Malware
Malicious software designed to target and compromise mobile devices, often leading to data theft, performance issues, or unauthorized actions.
- Can manifest as unexpected app installations, pop-ups, or battery drain.
- Often spreads through unofficial app stores, deceptive ads, or infected links.
- Examples include mobile viruses, Trojans, spyware, and ransomware.
