So, what’s the CIH virus all about?

In the bygone cyber world of 1998, a menace by the name of CIH virus, also called Chernobyl or Spacefiller virus, made a grand entrance. Named after Ukraine’s notorious nuclear disaster of 1986, this malignant piece of code was the brainchild of Chen Ing-Hau, a Taiwanese scholar.

Specially designed with Windows 95 and 98 in its crosshairs, CIH was a highly destructive force causing havoc in executable files and spreading its menace through tainted floppy disks and internet files. It had two lethal tricks up its sleeve:

1. System Hippocampus Wipe-out: CIH had an internal clock that provoked chaotic system corruption on particular dates, generally April 26 ( the day of the Chernobyl catastrophe), and June 26. It infused chaos by overwriting key system files and data, making the afflicted systems lifeless.
2. BIOS Corruption: In some versions, the virus also tried to mess with the computer’s BIOS (Basic Input/Output System) – the persistent taskmaster that initiates the computer’s hardware when it’s switched on. This resulted in the affected computer losing the ability to boot or run any programs.

CIH caught the world’s attention owing to its wanton destruction and far-reaching damage. It pounced on hundreds of thousands of computers across the globe, causing data havoc, triggering system failures, and making reinstalling operating systems a necessity.

Note that CIH is an outdated enemy and no longer poses a significant danger today. Thanks to advanced anti-virus software and superior security protocols, CIH’s reign of terror has been effectively controlled. Nevertheless, it remains a stark reminder of the potential damage that computer viruses can inflict and how crucial it is to keep security measures updated and effective.
