2022 Week 7 Security Summary

-

 

Summary

Sorry for the late release.  There was so little news I debated doing a 2-week report but decided Monday morning that the week of the 8th might turn out to be pretty busy.
The news of most interest is that we have seen a lot of increase in attacks against all aspects of critical infrastructure and with the threat of war in the Euro-Asian theater this is probably only going to increase.




News

News that spans all of the areas of this blog points out that we are increasingly seeing attacks against critical infrastructure sectors.  Once upon a time, these were generally considered off-limits by attackers and state actors as disruptions to these could affect lives or the supply chain and lead to very active state-sponsored reprisals.  The article points out that in the US alone attacks were launched against 14 of the 16 critical sectors last year (2021). 


ICS

Lloyd's released a report that dives in to the growing threat to Industrial Control Systems (ICS).  Among the findings in the report are:
  • Cyber insurance is maturing but still has trouble with cyber-physical risks.
  • Stakeholders should be actively monitoring products for risks.
  • While large-scale attacks are unlikely, the threat is growing.
  • Stakeholders need to be assessing the risks of attacks bridging Operational Technology (OT) and Information Technology (IT) networks.
  • There must be a focus on procedures as well as the components of ICS networks
  • Intelligence needs to be part of operations
  • More should be done to raise awareness of the risks

Siemens released 9 advisories that address 27 vulnerabilities in their Programmable logic controllers (PLCs).  They are tracked as CVE-2021-37185, CVE-2021-37204, CVE-2021-45106, and CVE-2021-37205.  

Healthcare

Memorial Hermann Health Systems in southern Texas notified patients of a breach via a contracted vendor named Advent Health Partners.  Over 6000 patients protected health information may have been affected.

  Summary This blog is geared towards cybersecurity events that are of interest to State, Local, Tribal, and Territorial (SLTT) governments in the United States of America.  It is hoped that this focus will help SLTT information technology workers and policymakers to get the information relevant to their mission.  If you are in other sectors hopefully there is information you can find useful as well.   News Windows Outlook Vulnerability The 0-Day for Microsoft Exchange Server keeps making news.  Over the course of the week threat actors outside of the Haifum Chinese cyber espionage group started to take advantage of the exploit.  Many new breaches were identified over the weekend as organizations large and small rushed to update vulnerable servers.  From the briefings I have sat through over the last week or so, I can only add my echo to the chorus saying that you should immediately patch your on-premises version of Outlook.  Here are some of the developments that we have seen: ZDNet a

  Summary Let me apologize for the long delay right upfront.  First, we had a round of Covid in the household in a person who is immune-compromised.  Next, I started a new semester in college and the workload was far greater than I expected.  Lastly, this is the start of the budget year for us and I had several projects that have demanded almost every second of my work time.  I hope to get back to weekly updates by November. Lots of news that covers:  health care, education, infrastructure, and SLTT governments around the world.  Since I am hitting the length limitations of Blogger, I will simply invite you to read and try and get caught up yourself.  News UC San Diego Health sued over breach In what is becoming a growing trend UC San Diego Health is being sued for failure to have proper data protection protocols.  The suit is citing breach of contract, negligence, and violating California consumer and medical privacy laws.  Specifically, the suit alleges failure to adequately train em

  Summary Sorry, this was late this week.  I was in training on Friday with the good folks at the LSU Academy of Counter-Terrorist Education.  If you are a Tribal or other American first responder or researcher in the field of terrorism and not taking advantage of their amazing resources, please check them out at  https://www.ncbrt.lsu.edu/ . Not a lot of new things this week.  There was an update from the City of Tulsa and their breach.  We also saw REvil disappear from both the Web and the dark Web.  Lastly, CIS tools are taking the forefront in the defensive posture of the SLTT landscape. News City of Tulsa Oklahoma breach Tulsa, which was breached back in May ( https://yasb2018.blogspot.com/2021/05/2021-week-19-security-roundup.html ), has announced that at least 27 people had their Social Security number accessed.  The city said they have attempted to reach out to those affected.  To date, more than 18,000 files from the hack have been released to the dark web. https://www.securit
