Hello all,

For our Jewish readers, Shanon Tovah! Last night marked the beginning of Rosh Hashanah, the first day of the Jewish New Year. For all of us, happy Patch Tuesday week – it has been a big one! It actually started the week prior with some rumblings of the WebP codec vulnerability, and then exploded with nearly everyone out there needing to scramble to patch the critical flaw. Then Patch Tuesday hit with Microsoft and a cadre of vendors releasing patches.

As usual, the complete Red-N Weekly Cyber Security News newsletter report is below the Notable Callouts. Don’t forget, our site, https://red-n-security.com also has searchable archives of past newsletters.

Notable Callouts:

  • Adobe leads the alphabet, so they get to be the first mentioned patch this week. Make sure you check all of your Adobe products for updates, not just Reader. Adobe has updated a lot of their offerings.
  • Google, Microsoft, Mozilla, Brave, and others have released updates for their browsers. Most were for the WebP vulnerability, but there were other patches as well. Patch quickly.
  • Columbia, yes, the country, is reporting that much of their infrastructure is down due to a ransomware attack on their hosting company. US-owned company IFX Networks provides web hosting services to 17 countries. In addition to the country of Columbia, the attack has affected 762 companies across Latin America.
  • Microsoft, amidst the Patch Tuesday updates, also put out a reminder that DC full Kerberos enforcement is coming soon. Check your event logs to ensure that things will continue to authenticate once they flip the switch in a future update.
  • Patch Tuesday from Microsoft brought fixes for 61 CVE’s, some of which are under active exploitation, so patch quickly.
  • Oracle and Microsoft – hell must have had a significant drop in temperature this past week. Larry Ellison actually sat on stage with Satya Nadella in Redmond, WA and announced that Oracle products would be available in Azure.
  • WebEx Some dirtbags managed to purchase the top result for when someone searches for WebEx and they are loading up malware. Always be wary of search results. The web is not a safe place.
  • WebP – I know I’ve mentioned it already, but this one is going to take a while to fully mitigate. The libwebp library is used in many products that render graphics, including Electron based apps. Check with your vendors for updates and statements relating to this vulnerability.

In Ransomware, Malware, and Vulnerabilities News:

  • MGM Resorts have been in the news all week due to the size of the ransomware attack. Late in the week it was revealed that a “10-minute phone call” was all it took for the waste-of-flesh criminals to trick the helpdesk into granting access. That brings up a very timely and critical question. How do you verify identity? What process does your helpdesk employ? Even knowing the person’s voice isn’t enough, as Retool found out. See below.
  • Retool a software development platform was hacked. Part of the vector involved using deepfake technology to impersonate someone’s voice to convince the helpdesk to provide access.

In Other News Events of Note and Interest:

  • North American Airspace Defense is getting a cloud-based backbone next month. When I read things like this, I can’t help but think the clock hands just moved a bit closer to SkyNet coming online.
  • Windows 11 will be getting a new feature to block NLTM attacks over SMB. Pay attention to this one as older devices could lose connectivity once enabled.
  • Google and Chromebooks. In a massive announcement that should provide a bit of a shakeup to the perpetual update cycle, Google has announced that they will provide 10 years of support for new Chromebooks starting in 2024.

In Cyber Insurance News:

  • The state of Illinois has passed legislation that affects you if you sell hardware or software that collects biometric information from one of their citizens.

The WebP vulnerability underscores the need to have layers of defense. You can be doing everything correctly, and an infrequently used software program, such as GIMP, could compromise your entire network unless it has proper defenses in place.
