Utilizing AI in Cybersecurity: DevSecOps, Types of Hackers, Threat Detection and Vulnerability Management | Cyber With Spider #cyberwithspider
Types of Hackers
- White Hat Hackers:
- Also known as ethical hackers.
- They use their skills to improve security by finding and fixing vulnerabilities.
- Often work as security analysts or consultants.
- Black Hat Hackers:
- These are the malicious hackers who exploit vulnerabilities for personal gain or to cause harm.
- Engage in illegal activities such as data theft, spreading malware, and financial fraud.
- Gray Hat Hackers:
- Operate between white and black hats.
- They may exploit vulnerabilities without permission but usually report them afterward, sometimes seeking a fee for the information.
- Script Kiddies:
- Inexperienced hackers who use existing scripts or programs to attack systems.
- They typically lack the knowledge to create their own exploits.
- Hacktivists:
- Use hacking to promote political agendas or social change.
- Their attacks are often aimed at drawing attention to a cause.
Virus
Virus:
- A type of malware that attaches itself to a legitimate program or file and spreads to other programs and files when executed.
- Can corrupt or delete data, and spread to other systems.
Malware
Malware:
- General term for malicious software designed to harm, exploit, or otherwise compromise a system.
- Includes viruses, worms, Trojans, ransomware, spyware, and more.
Work
Work (in the context of malware):
- Malware can perform a variety of malicious actions such as stealing data, encrypting files for ransom, spying on user activity, creating backdoors for future access, and disrupting services.
Trojan Horse
Trojan Horse:
- Disguises itself as a legitimate program but performs malicious activities when executed.
- Can create backdoors, steal data, or download additional malware.
Spyware
Spyware:
- Covertly gathers information about a user without their knowledge.
- Can track browsing habits, record keystrokes, and steal sensitive information.

Little History
History:
- Early cybersecurity incidents include the Morris Worm in 1988, which caused significant disruption on the early internet.
The Morris Worm, released on November 2, 1988, was one of the first . - The Morris Worm caused widespread disruption across thousands of systems connected to the ARPANET, the precursor to the modern internet.
- The worm self-replicated and spread quickly, infecting an estimated 6,000 machines (around 10% of the entire internet at the time) within a few hours.
- The worm didn’t damage files, but its rapid replication caused machines to become sluggish, or even crash entirely, as they struggled to handle the worm's processes.
- Viruses like the 1982 Elk Cloner and the 1986 Brain virus were among the first to spread widely.
- The rise of the internet and interconnected systems increased the need for robust cybersecurity measures as threats became more sophisticated and widespread.
What They Do
What Malware Does:
- Viruses: Infect files, corrupt data, and spread to other systems on network.
- Worms: Replicate across networks, consuming bandwidth and resources. It speard Independently. It can effect within few minutes in network. No user interaction requried. Rapid spread. within 24 it effect lac of systems in history, can slow network, steal data, distrupt system.
- Trojans: Create backdoors, steal data, and download additional malware. It show it is usefull but it is not. Even sometimes we use it. Steal data , Damage or gain remote access. No selef replicate , User interaction needed. to insert virus, worm.
- Spyware: Monitor user activity, steal information, and send it to attackers. Using username password, picture , can check keystrokes. No privacy.
- Ransomware: Encrypt data and demand payment for decryption keys. Locks system. Crypto address to send money, It is difficult to track.

Virus can effect boot sector (this is other then simple files), Like some lines show due to firmware infection.
Drop a Good antivirus name. (I dont use any kind of antivirus)
The Brain virus, created by two Pakistani brothers, Basit Farooq Alvi and Amjad Farooq Alvi, in 1986, is often recognized as the first true computer virus to infect the MS-DOS operating system, specifically targeting the boot sector of floppy disks.
- Creeper (1971) was the first self-replicating program (but not malicious).
- Brain (1986) was the first true malicious computer virus.
The Morris Worm (1988) infected approximately 6,000 computers (about 10% of the internet at the time). It caused significant disruption by consuming system resources and slowing down networks.
