Android Vulnerabilities Overview (AVO) is a databse of known security vulnerabilities in Android.

The vulnerabilities database is splitted into seperate .md files to get an better and cleaner overview. The current 2016 list is avaible over here.

The security flaw gives hacker ability to spy on Android smartphone owners, steal login credentials, install malware, and many more, according to the latest research conducted by the researchers at the Pennsylvania State University and FireEye.

Attacks

• Ransomware (User needs to confirm the device admin part)
• Distributed Denial of Service (DDoS)
• Cyber-attacks like (mass) surveillance (e.g. directly on telecommunication infrastructures), worms, viruses, trojans, ...
• Hijacking in Android is a common problem, see also Clickjacking
• Cyberterrorism (Data Theft, DOS, ...)
• Remote Access Tools (RATs)
• Fingerprinting to sniff metadata
• Impersonation Attack
• Session Fixation Attack
• Cache-Poisoning Attack
• Heap thermal vision problems attacks/bugs
• Other data leakage, exploits, 0day, ...

Spyware Capabilities

• Listening in to telephone conversations
• Accessing the Internet
• Viewing and copy contacts
• Installing unwanted apps
• Asking for location data
• Taking and copying images

Forensics analysis software and apps

In most cases Trojans/Malware only sending 'stuff' to there C&C's if you're on wifi (to not getting easier detected by the bandwidth consumptation itself), of course they often drain your battery, so some tools are to detect such cases and identifys them (like Hush) such tools can be used to reveal what exactly going on behind the scenes.

‘Stingrays’ Cell Phone Trackers

Stingrays, made by the Harris Corporation, has capabilities to access user's unique IDs and phone numbers, track and record locations, and sometimes even intercept Internet traffic and phone calls, send fake texts and install spyware on phones. The authorities used these tracking tools for years to breach people's privacy and did everything to keep even the existence of these devices out of the public eye. They even avoid telling judges when they used them.
