Madhu Kalale's Key Ideas from Cybersecurity
by Joaquin Jay Gonzalez III

Crackers are the ones that are typically engaged in trading and publishing 'cracks' for games, patches, serial numbers and activation keys for commercial software. They may embed malware in their cracks and patches called as Trojans. If these cracks are used, there is risk of getting infected with worms or viruses.

Script Kiddies, or 'Skiddies' are amateur hackers who adapt other people's exploits to attack institutions and may take part in online anonymous protest groups.

Black Hat Hackers develop malware, intrusion techniques and tools for evil purposes and have an ulterior motive of profiting from it. Spy agencies, criminal groups and enemies of establishments tend to pay them for such exploits.

White Hat Hackers, or Ethical Hackers maybe good guys or security researchers who undertake penetration testing and security audits, while operating within the law. They report vulnerabilities to help fix the loopholes.

Grey Hat Hackers may expose vulnerabilities to fraudulent actors and may report vulnerabilities anonymously.

These are state-sponsored military personnel trained in hacking techniques.

They may use malware and hacking to spy or steal intellectual property to gather enemy intelligence.

Spammers use spambot programs to send automated emails, messages, tweets etc. to entice the potential buyers of their products.

Phishers may use similar techniques disguised as click baits, to entice their victims to download and install malware.
