Changing Default Behavior

We’re introducing a default change for five Office apps that run macros:
VBA macros obtained from the internet will now be blocked by default.

Google's Project Zero has published a report showing that organizations took less time to address the zero-day vulnerabilities that the team reported last year.

• In 2021, vendors took an average of 52 days to fix security vulnerabilities reported from Project Zero. This is a significant acceleration from an average of about 80 days 3 years ago.
• In addition to the average now being well below the 90-day deadline, we have also seen a dropoff in vendors missing the deadline (or the additional 14-day grace period). In 2021, only one bug exceeded its fix deadline, though 14% of bugs required the grace period.
• Differences in the amount of time it takes a vendor/product to ship a fix to users reflects their product design, development practices, update cadence, and general processes towards security reports. We hope that this comparison can showcase best practices, and encourage vendors to experiment with new policies.
• This data aggregation and analysis is relatively new for Project Zero, but we hope to do it more in the future. We encourage all vendors to consider publishing aggregate data on their time-to-fix and time-to-patch for externally reported vulnerabilities, as well as more data sharing and transparency in general.

UPnProxy is alive and well. There are 277,000 devices, out of a pool of 3.5 million, running vulnerable implementations of UPnP. Of those, Akamai can confirm that more than 45,000 have been compromised in a widely distributed UPnP NAT injection campaign.

FritzFrog is a peer-to-peer botnet, which means its command and control server is not limited to a single, centralized machine, but rather can be done from every machine in its distributed network. In other words, every host running the malware process becomes part of the network, and is capable of sending, receiving, and executing the commands to control machines in the network.

CISA has added one new vulnerability to its Known Exploited Vulnerabilities Catalog, based on evidence that threat actors are actively exploiting the vulnerability listed in the table below. These types of vulnerabilities are a frequent attack vector for malicious cyber actors of all types and pose significant risk to the federal enterprise.

"This document describes the security content of macOS Monterey 12.2.1."

"Apple on Thursday released security updates for iOS, iPadOS, macOS, and Safari to address a new WebKit flaw that it said may have been actively exploited in the wild, making it the company's third zero-day patch since the start of the year."
