Study Notes
Malware Types
- Worms are a type of malware known for their active propagation.
- Trojan horses are a type of malware that stays in memory.
- Logic bombs are a type of malware known for their unexpected functionality.
- Backdoors are a type of malware used for unauthorized access.
- Rabbits are a type of malware that can exhaust system resources.
Virus Information
- Viruses can live in system memory, executable files, boot records, or macro files.
- The Elk Cloner is considered a prototype for later viruses.
- The Michelangelo virus caused more annoyance than harm.
- The Friday the 13th virus had not much reaction from users.
Malware Detection Methods
- Signature detection is a method of malware detection that involves searching for known signatures in files to identify the presence of known malware.
- The purpose of signature detection is to identify known malware by comparing code patterns.
- Encrypted viruses evade signature detection by encrypting their code.
- Change detection is a method of malware detection that involves monitoring the system for changes, but has no proven track record.
- Anomaly detection is a method of malware detection that involves monitoring the system for anything 'unusual' or 'virus-like', and can detect unknown malware, but often results in false alarms (false positives).
- Behavioral detection is a method of malware detection that involves monitoring system behavior and can detect unknown malware.
- Integrity checking is a method of malware detection that involves hashing files and comparing hash values to detect changes, but may result in false positives.
Botnets and Worms
- A botnet is a network of compromised computers that can be controlled remotely.
- The purpose of a botnet is to conduct malicious activities such as DDoS attacks.
- The Storm botnet was responsible for infecting an estimated 10 million hosts.
- A flash worm is a type of worm that can rapidly spread and infect systems.
- The main characteristic of a botnet is a network of compromised computers.
- The main advantage of a flash worm is its ability to rapidly spread and infect systems.
Malware Defense
- Anomaly detection is used to defend against attacks by monitoring system behavior.
- Whitelisting involves only allowing known good programs to run, while blacklisting involves blocking known bad programs.
- Encrypting the decryptor code in a virus makes it harder to detect.
- The purpose of anomaly detection is to detect unknown malware.
