Ten years ago: first tweets about a new malware using a weird LNK vulnerability. Early names we used for it included 'W32.Temphid!lnk' and 'Rootkit.Tmphider'. Later, it was renamed...to Stuxnet. Stuxnet contained these strings:
".stub" and "MrxNet.sys".
That's where the name "Stuxnet" came from.

1/ Practically every startup ends up writing code, even if technology wouldn't be the main focus of the company. Here’s a checklist I made to help you and your hot new startup avoid the most common infosec pitfalls. [thread] 2/ Speed is the enemy of security.
The faster you move, the faster you develop, the faster you deploy — the less time you have for bug checking, quality assurance and testing. Security is not something you can add to a ready product, it has to be built in from the design phase.
