Firstly as we get started, allow me to say that camDown helps stop foreign state actors (FSA's) from accessing your webcam!

As we settle into the new year, it is important than ever to stay diligent about maintaining proper data security measures and to quickly resolve any newly discovered security vulnerabilities. In our latest security digest, we’ve curated news about the FlexBooker data attack, a very dangerous memory corruption vulnerability called Pwnkit, how a cloud storage misconfiguration left sensitive data openly accessible, a great example of why it is important to plug any holes in leaky AWS S3 buckets, and more.

FlexBooker Data Breach Impacts Over 3.7 Million Users

  • Accounts of more than three million users of FlexBooker, an appointment scheduling service, were stolen in an attack before the holidays and are being traded on hacker forums. The same intruders are offering databases claiming to be from two other entities: racing media organization Racing.com and Redbourne Group’s rediCASE case management software, both from Australia. All three breaches allegedly occurred a few days before Christmas and the intruder published the data on a hacker forum. Read more at Bleeping Computer.

Huge Linux PolicyKit Security Vulnerability Discover, Called “Pwnkit”

  • A serious memory corruption vulnerability in polkit (formerly PolicyKit) has finally been discovered after 12+ years. This program is found in essentially all modern Linux distributions. Security company Qualys has uncovered a truly dangerous memory corruption vulnerability in polkit’s pkexec, CVE-2021-4034. According to Steven Vaughan-Nichols, this vulnerability is “easy to exploit. And, with it, any ordinary user can gain full root privileges on a vulnerable computer by exploiting this vulnerability in its default configuration.” Read more ZDNet.

Cyber-Attack on Global Affairs Canada

  • Global Affairs Canada was hit a day before the Canadian Centre for Cyber Security issued a cyber-threat bulletin urging critical infrastructure operators to strengthen their defenses against known Russian-based cyber-threat activity. The attack came as the United States Department of Homeland Security warned that the US response to a possible Russian invasion of Ukraine could make the US a target of cyber-attacks by the Russian government and its proxies.

Bernalillo County Ransomware Attack Still Felt Weeks Later

The attack impacted the 675,000 residents in Bernalillo County, including those living in New Mexico’s most populous city, Albuquerque. Read more at National Cybersecurity News Today.

Linux Kernel Bug Can Let Hackers Escape Kubernetes Containers

  • A vulnerability affecting Linux kernel and tracked as CVE-2022-0185 can be used to escape containers in Kubernetes, giving access to resources on the host system. Security researchers warn that exploiting this security issue is easier and more promising than initially estimated, and that patching is an urgent matter since the exploit code will soon become public.

Owl fun and facts:

SALT LAKE COUNTY — A Utah Highway Patrol trooper had an unusual rescue on New Year’s Day, saving an owl that had been hit on I-215 in Salt Lake County.
