CrowdStrike? EDR? A sheriff shooting civilians? A vaccine with painful side effects?
Even now that I'm unemployed and no longer working in the IT industry after having worked there for many years, I'm still interested in news about IT-related troubles. The trouble that occurred around the world on July 19th is said to be the largest in history in terms of scope and scale.
The low-cost carrier at Narita Airport that I occasionally use was also suspended.
"CrowdStrike" is apparently an EDR software. Both names are unfamiliar to me.
The IT industry often uses imported English abbreviations to express new technologies. Before the term EDR, I heard the word EPP. In the world, it was said to be "antivirus software" or even shorter, "virus software."
In the early 2000s, computer viruses such as Nimda and Code Red wreaked havoc. Antivirus software manufacturers such as Trend Micro and Symantec were busy dealing with new types of viruses that appeared one after another (most recently, a malware called EMOTET caused great damage).
When I went to IT exhibitions held at Tokyo Big Sight or Makuhari Messe, women dressed as nurses were advertising antivirus software.
Recently, rather than causing trouble to an unspecified number of people, attacks targeting people from whom money can be stolen are on the rise.
In response to the increasing sophistication of attacks by cyber attackers, EDR was developed as a countermeasure for computer systems.
So why did CrowdStrike, which is supposed to protect the system, attack (strike) the system?
The latest CrowdStrike issue occurred on a Windows PC, but according to this article, CrowdStrike issues have also occurred on Linux in the past.
There have been cases of similar bugs in the past at other companies. In 2005, Trend Micro, a major antivirus software manufacturer, made a mistake in creating a pattern file to identify virus software, causing PCs to enter an infinite loop. The company where I worked at the time also suffered great damage.
This kind of thing happens in the past and now too.
