+## Description
+
+We want to take a look at the Crowdstrike bug that happened in July of this year. 
+Crowdstrike is a company that sells anti-malware services, endpoint protection software, and threat-intelligence services.
+On the 19th of July 2024, a new version of one of their softwares caused over 8 million Windows computers to crash, due to a array out-of-bounds memory exception.
+This was not caught in any of the testing done by Crowdstrike prior to deployment. The tests used Regular Expressions, and wildcard matching that missed the oob-exception every time. 
+Since the software in question is running in kernel level 0, this was catastrophic for the computer, and caused an system-wide crash. 
+We will look at how the automated testing failed, aswell as what Crowdstrike have done(or could have done) to fix it. 
+
+**Relevance**
+
+The bug in the update should have been caught by the automated testing Crowdstrike ran before deployment. 
+However, due to the way that the tests were set up, this issue slipped through all tests and made it to live. 
+This issue higlights the importance of not only having tests, but writing good tests. Just because your commit passes all tests does not mean that it's 100 procent safe.
