3.3 - CompTIA A+ Core 2

Unofficial application stores

Platforms where users can download apps not vetted by official developers, increasing risks of malware and data breaches.

Developer mode

Enables developer-specific settings for mobile devices, such as USB debugging and memory statistics.

Rooting

The process of gaining root access to the core of an Android OS, allowing modification of files and system settings.

Jailbreaking

The process of removing software restrictions imposed by Apple on iOS and related devices.

Application spoofing

Installation of apps that appear legitimate but are actually malicious; always verify the source.

High network traffic

Refers to higher than normal network use, which may indicate problems or malware.

Data-usage limit notification

Alerts users when they approach or exceed their data cap, potentially leading to reduced speeds or additional charges.

Limited/no internet connectivity

Occurs when a device cannot establish a stable connection to the network, often due to router or ISP issues.

High number of ads

Large number of advertisements - a symptom of potential malware; running an anti-malware utility can help remove the source.

Fake security warnings

Legitimate-looking alerts that trick users into installing additional malware; users should avoid downloading prompted software.

Unexpected application behavior

Manifestations include crashing, slow performance, or unusual error messages; updating or reinstalling the app is recommended.

Leaked personal files/data

Loss of data that indicates potential security breaches; remediation involves performing scans, factory resets, and changing passwords.
