WannaCry Takeaways In addition to the point about not using outdated, unpatched systems, WannaCry left the industry with some other significant lessons — though many companies fail to heed them.

Just a few thousand machines could yield a widespread distribution of WannaCry across the world, with a speed and scale that hasn't been seen since the MyDoom email worm that affected Microsoft computers in 2004. The exploit technique is known as heap spraying and is used to inject shellcode into vulnerable systems allowing for the exploitation of the system. Alexandra Simon-Lewis.
