Mayanei Hayeshua Medical Center in Bnei Brak was hit by a cyberattack on August 7. Patient care was not disrupted for some things, but the ministry instructed that the center’s outpatient clinics and imaging centers not accept patients and that the public not go to its emergency room until further notice. A week later, the hospital disclosed it had received a ransom demand. It was pretty much an open secret that the attackers were the Ragnar_Locker group, but the hospital never named them.
Now the threat actors have started leaking data, prefaced with a message:
Greetings!
First of all, we want to emphasize that since this is a medical institution – we didn’t run any encryption to avoid equipment malfunctions, or necessary instruments. However, serious vulnerabilities allows us to download a lot of data and someone else in our place could use such vulnerability in any other way.
We tried to draw their attention to the network issues and called them for discussion. Instead of the dialogue, they decided to play tricks with us, they even tried to catch us with phishing. Come on guys, seriously?
So, after multiple attempts to contact with management of MYMC, it becomes clear for us, that management of MYMC doesn’t care about the privacy of own patients, sad to state this fact but it’s true.
Today we are posting the first batch of MYMC internal files, you can find among those a lot of personal information, internal emails, finances, medical cards and more of highly sensitive data.
But this is not all, in next 3-4 days we will upload to public view full SQL database and huge bunch of .pst files with internal correspondence.
Expect for the updates and keep your privacy in your own hands.
According to our rules we are publishing the data which were compromised during security research of the MYMC network.
“Those organizations who collecting and storing private data, should be in charge of it’s privacy.”
One wonders whether the hospital is fully aware of all of the vulnerabilities the attackers claim to have discovered. If they haven’t, they are likely to be reattacked or attacked by another group.
