After cyberattack, Tri-City Medical Center documents reportedly found on dark web

Tri-City Medical Center has been up and running for a few weeks, but itโ€™s still feeling the effects of a cyberattack that affected operations in November. KPBS North County reporter Jacob Aere says now it appears some patient data has been posted online.

Just days ago, a cyber security expert posted on social media that an extortion operation called INC RANSOM was claiming it had records stolen from Tri-City Medical Center โ€” and that some were posted on the dark web.

โ€œWhen someone posts online, theyโ€™re showing almost as proof that they have breached the system, and typically will follow that with some type of a demand,โ€ Cyber Center of Excellence CEO Lisa Easterly said.

The post included โ€œproofโ€ in the form of eight pages presumably taken from Tri-City during the digital attack, University of San Diego professor of cybersecurity Nikolas Behar said.

โ€œWe're seeing them post things like patient authorization forms, financial records and they're going to contain things like name, phone number. But weโ€™re not certain if they accessed any of the electronic medical records,โ€ he said about the INC RANSOM post.

Tri-City did not respond to a request for an interview or statement on the matter.

Easterly said everyone should practice proper digital hygiene to protect themselves from cyberattacks. That includes turning on multi-factor authentication, updating software, using strong passwords and thinking before you click on a link to not fall victim to a phishing scam.

As for victims of a cyber security breach, she has further advice: โ€œMonitor your credit. You can request free credit reports from all three credit bureaus and place freezes on your credit and your childrenโ€™s credit. This is very important, to help thwart potential identity theft,โ€ Easterly said.

The FBI has recorded a large increase in cybercrime complaints and financial losses since the COVID-19 pandemic when much of our lives shifted online.

โ€œIf you are a victim where they are putting it online, first things first is โ€” get in touch with your local FBI office or your law enforcement fusion center,โ€ Easterly said.

Currently, Behar said there is no indication of just how many Tri-City records might be in the attackerโ€™s possession.

Then, a city report says San Diego is eight billion dollars short in funding for infrastructure projects. Next, registered nurses in the county joined protests taking place across eight states. Also, a new complex in National City has 94 units, but has received more than a thousand applications. As well as, the VA has reversed course on changing the rules on how disability benefits are decided.
