1. PROBLEM
STATEMENT ON SECURITY

2. ADVANCED ETHICAL HACKING

3. WHAT HAPPENED WITH CAMSCANNER
Kaspersky researchers discovered that recent versions of the
CamScanner app for Android shipped with a malicious Trojan
Dropper module that had the potential to show intrusive ads and
signed users up for paid subscriptions. Before being removed,
CamScanner had more than 100 million downloads.

4. WHAT IS TROJAN-DROPPER
Software that injects Trojans, viruses, worms and other malware into
a computer. When run, it typically decompresses the malware
components hidden within the dropper file and executes them,
sometimes without saving them on disk to avoid detection. The
Trojan dropper may appear to users as legitimate software that they
want to install. To avoid detection, droppers may also include images
and other benign data in their package.

5. SOURCES OF INFECTION
Most of the time, the user gets infected by using some
unauthenticated online resources. Infections are often consequences
of activities like:
1.Clicking malicious links or visiting shady websites
2.Downloading unknown free programs
3.Opening attachments sent with spam
4.Plugging infected drives
5.Using Infected proxy (like in case of OnionDuke)

6. PREVENTION METHOD
Malwarebytes protects users from Trojan.Dropper by using real-time
protection.
