Great post, David. That PPMG let something as sensitive as social security numbers and healthcare data sit unencrypted is absolutely negligent, made even worse that a single credential was able to access all of it. Your recommendations of encryption, both at rest and in flight, and strict network segregation to silo sensitive information away, and accessible only on a need-to-know basis, should be immediately implemented.
What a well written post! PPMG responded well in terms of identifying and addressing the breach, notifying patients, and complying with legal obligations. However, it’s true that the breach itself could have been prevented or mitigated with stronger security practices, especially around authentication, encryption, and employee awareness. While their response was appropriate, it serves as a reminder of the importance of proactive security measures to prevent such incidents from occurring in the first place.
David, this post does a fantastic job of presenting the details and implications of the PPMG data breach. The timeline of events and breakdown of the compromised information provides clarity on how this incident unfolded. The quick response of PPMG’s, including especially their steps to notify affected individuals and offer credit monitoring, is commendable.
This highlights the need for effective staff cybersecurity training, as human error often plays a critical role in breaches.
Your blog highlights the alarming vulnerabilities that exist when it comes to healthcare data security. One of the most striking details of your blog, and this case, is how a single compromised credential can cause such damage. Of course, it raises important questions about why MFA and other more robust access controls weren’t already in pace. However, keeping information secure in healthcare settings is particularly challenging due to legacy systems, complex and interconnected systems, high stakes environment, 24/7 operations, resources, regulations, and of course – the human error. Human error is especially painful, as an entity can have the best security features and controls, and all it would take is one person (maliciously or not) to fail to use them, use them incorrectly, or exploit them. Therefore, I believe that staff training – the need for entities to view cybersecurity as a fundamental part of training is absolutely essential going forward. This would also require a cultural shift. After all, how many people do you know that skip through or click through their security training? In addition to that, to truly address the issues here, we must push for stronger, industry-wide standards that prioritize security over convenience when it comes to entities that handle sensitive data.
Thanks for the post. I think that aside from security awareness, MFA, and other security controls, this breach occurred from a third-party application and for an organization as critical as this, they appear to not have adequate procedures in place for a third-party risk management program. On the other hand, there might’ve been a program in place but lack of oversight in their vendor management practices. That is one thing that stood out to me. In addition to that, I agree that security awareness is one of the most important controls to have in place because even when all possible controls are in place, all it takes is for one employee to click on a phishing link or use a weak password. Health information is extremely sensitive and regarding personal information in general, the damage caused from breaches in some cases can be extreme so it is definitely better for organizations to not only focus on the technical controls but also people controls and their relationships with their vendors.
Thanks for the detailed post, David. The PPMG breach highlights the urgent need for strong security measures, such as encryption, MFA, and comprehensive staff training. While their response was quick, it’s clear that stronger data protection practices and better vendor oversight could have prevented the breach. This case also emphasizes the importance of being proactive with security, rather than relying solely on reactive measures. It serves as a reminder of the challenge of balancing security and convenience, particularly in sensitive sectors like healthcare. Ultimately, it reinforces the need for a multi-layered security approach, blending both technology and human awareness.
Great post David, I like the way you laid out the information. I think it is interesting to think about when they decided to notify users. I wasn’t right the day they detected the issue, which makes sense as they don’t know to what extent it is. It wasn’t 4days later after they noticed they were adding on a dark web leak website or when they hired a cyber security company. It was only after notifying the attorney general almost 3months later did they notify users. I am not even suggesting they did anything wrong, this might all be the industry standard. I just wonder how many people where at risk of fraud within that period without knowing anything, and if there is anything we can do to avoid this.
