Everyone's New Year's Resolution should be to stop using passwords altogether.

The final Patch Tuesday of 2023 is upon us, with Microsoft Corp. today releasing fixes for a relatively small number of security holes in its Windows operating systems and other software. Even more unusual, there are no known "zero-day" threats targeting any of the vulnerabilities in December's patch batch. Still, four of the updates pushed out today address "critical" vulnerabilities that Microsoft says can be exploited by malware or malcontents to seize complete control over a vulnerable Windows device with little or no help from users.

Facebook users are notoriously the biggest offenders for sharing fake news and misinformation.

Nearly 20% of the zero-day flaws that attackers exploited in 2022 were in network, security, and IT management products, Mandiant says.

As many as 55 zero-day vulnerabilities were exploited in the wild in 2022, with most of the flaws discovered in software from Microsoft, Google, and Apple. While this figure represents a decrease from the year before, when a staggering 81 zero-days were weaponized, it still represents a significant uptick in recent years of threat actors leveraging unknown security flaws to their advantage. The

The zero-day exploitation of a now-patched medium-security flaw in the Fortinet FortiOS operating system has been linked to a suspected Chinese hacking group.

**What is the relationship between Mark of the Web and Windows SmartScreen?** When you download a file from the internet, Windows adds the zone identifier or Mark of the Web as an NTFS stream to the file. So, when you run the file, Windows SmartScreen checks if there is a zone identifier Alternate Data Stream (ADS) attached to the file. If the ADS indicates ZoneId=3 which means that the file was downloaded from the internet, the SmartScreen does a reputation check. For more information on SmartScreen, please visit Microsoft Defender SmartScreen overview | Microsoft Learn.

**According to the CVSS metrics, successful exploitation of this vulnerability could lead to major loss of confidentiality (C:H), integrity (I:H) and availability (A:H). What does that mean for this vulnerability?** An attacker who successfully exploited this vulnerability could access a user's Net-NTLMv2 hash which could be used as a basis of an NTLM Relay attack against another service to authenticate as the user.

Government entities and large organizations have been targeted by an unknown threat actor by exploiting a security flaw in Fortinet FortiOS software to result in data loss and OS and file corruption.
