Microsoft released 63 security patches for November, including a fix for a zero-day vulnerability already under active exploitation. Of the patches, 12 updates are considered critical, and almost every other patch is ranked as important. Out of the 12 critical vulnerabilities, 10 can be exploited through browsers or opening malicious files, according to a post from Jimmy Graham of Qualys. “The priority this month should be all Windows OS updates and Edge,” said Chris Goettl of Ivanti. “Internet Explorer has several Important vulnerabilities resolved as does Office, but all of the Critical vulnerabilities, exploits and disclosures are in the OS and Edge browser.” Goettl also notes Microsoft is re-releasing Windows 10 1809 and Server 2019 after pulling them in October due to user data being deleted after upgrading. “Take a moment to test before rolling out just to be cautious,” he said.

We update monthly on Patch Tuesday, install firewalls, anti-virus and anti-spyware, and always coach users to use complex, secure passwords. But apparently it is still not enough. A recent poll of 300 hackers conducted at Black Hat finds Windows OS is still a very hot target for attack. Those that answered the survey were a combination of white hat, gray hat and black hat hackers. Nearly 50 percent of those surveyed said they had compromised Windows-based systems more than any other within the past year. Most said they infiltrated Windows 10 most frequently, followed by Windows 8. Microsoft says Windows 10 has been deployed on 700 million devices since its launch in 2015. Microsoft has prioritized security in recent years, recently noting it will continue to invest over $1 billion a year on cybersecurity and research in order to further enhance the defenses of its products. But clearly, Windows is still seen as a sitting duck for hackers seeking a quick win. Why is that? “With more than 80 percent of the desktop OS market share, it is no surprise that Windows is a hot target for hackers,” said Michael Maltsev, a security researcher at Reason Software Company. “Microsoft is well aware of this, and … Read More
