A Brief History of Cybersecurity: Early Threats and Modern Solutions
History of Cybersecurity Incidents:
- Early cybersecurity incidents include the Morris Worm in 1988, which caused significant disruption on the early internet.
- Notable threats like the Morris Worm were among the first major cybersecurity threats.
- Networks connected to ARPANET were affected, as it was the precursor to the modern internet.
- Rapid replication of the worm infected an estimated 6,000 machines within a few hours, causing systems to become sluggish or crash.
- Malicious Viruses like the 1982 Elk Cloner and the 1986 Brain virus were among the first to spread widely.
- Growing reliance on 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.
