Hackers accidentally send their malicious code to Microsoft
According to one of the senior security architects, Rocky Heckman, When in the process of developing viruses, the viruses themselves fall with an error, the code is often sent directly to Microsoft.
When a hacker application crashes in Windows, as with all typical crashes, the system will prompt the user to send the details of the error — including the malicious code — to Microsoft. As Heckman noted, the funny thing is that many are too tight to “Send.”
“People send us the virus code when it constantly crashes during the development process,” says Heckman. “It's amazing how much material we collect.”
