“The Worst” Windows Bug Discovered... and Thankfully Fixed

Microsoft has resolved what a security researcher tweeted was “the worst Windows remote code exec” in his memory. This vulnerability allowed a targeted file to implement remote code execution processes, manipulating the infected system and spreading the infection to other machines. In other word, it’s a bad problem to have. The scariest part: the attack would be triggered if a particular file were to be scanned by the Microsoft Malware Protection Engine.

This vulnerability was uncovered and reported by researchers Tavis Ormandy and Natalie Silvanovich, of the Google Project Zero team. Taking to Twitter, the duo reported that they had made a discovery, reporting it to Microsoft and the Microsoft Security Response Center.

The MSRC confirmed the presence of the vulnerability, discovering that numerous pieces of software within the Microsoft Malware Protection Engine would allow a “specially crafted file” to begin running any code the attacker pleased on the system. This vulnerability was present on essentially every Windows machine, having been found on Windows 7, 8.1, and 10, and even affecting Windows RT.

While Microsoft pushed out this particular update, this story still serves as a reminder to keep all of your solutions up-to-date. There is a digital arms race that is waged between programmers and hackers, where each side tries to gain the upper hand over the other by improving their programs. This is one of the main reasons why your solutions have regular updates released, and why it is so important to implement these updates in a timely manner. Without these updates, your system is left vulnerable to threats that have been made preventable.
