  2. OUTLINE • What is a RootKit ? • Installation • Types • How do RootKits work ? • Detection • Removal • Prevention • Conclusion • References

  3. What is a RootKit ? • Software that allows continued privilege access to a computer system without the system users knowledge. • RootKit comes from “Root” – UNIX administrator account and “Kit” – Software components that implement the tool.

  4. INSTALLATION • Exploit Security Vulnerabilities • Cracking a Password • Trick user into executing malicious code • Social Engineering • Malware is beneficial

  5. TYPES • Persistent • Activated every time system starts up • Non-persistent • Not capable of running again on system start up • Way in which they execute • User Mode • Kernel Mode

  6. How do RootKits work ? • RootKits use a simple concept called “Modification” • Some places where modifications can be made in the software: • Patching • Easter Eggs • Spyware Modifications • Source-Code Modifications • Legality of Software Modifications

  7. DETECTION • Alternative trusted medium • Behavioral-based • Signature-based • Difference-based • Integrity-based • Memory Dump

  8. REMOVAL • Re-install OS from trusted media • Highly recommended • Re-install from scratch • Anti-virus software • Malicious software removal tool • AVG Pro • SpySweeper

  9. PREVENTION • Use Anti-virus Software • Install a Firewall • Use good passwords • Keep Software up to date • Follow good security practices

  10. CONCLUSION • Thus, we have seen what Rootkits are, how they work, how can they be detected and removed and also what are the prevention mechanisms. • We also conclude that there is no concrete method to detect and remove RootKits.
