You can read the first in the series here , and the second here. You can also share your feedback with us on Twitter. The idea of a computer virus preceded computer networks. German mathematician John von Neumann famous for major contributions to economics, such as game theory first theorized the concept in the late s.
He envisioned a computer virus as an automatically self-replicating entity. But it was another 30 years before someone created one. But what did the mysterious message mean and who sent it? One of its researchers had created Creeper. Creeper was a worm—a type of computer virus that replicates itself and spreads to other systems. It only displayed its taunting challenge. Following Creeper, which was isolated within the realm of researchers, Elk Cloner was the first virus to be detected in the wild.

Meanwhile, it was clarified that Microsoft did not provide a complete patch for CVE The threat of the PrintNightmare Exploit is real. It could lead to:. Other people are now investigating the issue. Matthew Hickey and Benjamin Delpy also made some experiments. The first used a Windows Server Machine exposed to PrintNightmare exploit threat that was updated and managed to get full system privileges through a usual Domain User account and the latter could get REC on a system that was entirely patched.
Therefore the current Windows updates do not stop the newly discovered PrintNightmare exploit and it is a real threat, until fixing it.

Systems on the UW private networks are also at risk through indirect attacks, and depending on their configuration, most network firewalls will not block this attack.
Priority should be given to mitigations for domain controllers and servers, but all Windows computers need to be addressed. If you use Windows on your personal computers and devices that are not managed by UW, configure them to update automatically.
Alternatively, you can update manually by running Windows Update, but you must remember to check for updates often.
