Not sure if this is the right forum for this so please move if not correct..

Freyberg School in Palmerston North

School servers hit with ransomware

"The expert's best guess for how the hackers broke into Freyberg's servers was that they exploited a temporary password used by contractors hired by the Ministry of Education to carry out a recent systems upgrade."

Bit of a whoopsie there. Goes to show, your security is only as strong as the weakest link.

IME (and I've seen a lot of ransomware'd systems lately), they try blaming it on someone leaving an account enabled etc, but when its actually looked into, it turns out someone got an email with a dodgy attachment and well... you know the rest.

Its not "hackers" - its generally script kiddies.

How did they trace it back to china ? Just because the email address in the ransom is located there ?

Even with "experts" checking it and saying it was an RDP attack, the IT co. was prob asked not to say it was an email attachment because it'll make the school staff look stupid.

RDP attacks are possible and I have seen it first hand with a company that got hit by ransomware. RDP open to outside world on default port, AD password is 'password or 123', RDP into server and do what you feel like.If it was an RDP attack then it should make them feel more stupid because

1. Why leave RDP open on default port to open work without using RDS gateway or at the very least change default RDP port or force everyone to VPN first into school network from offsite and then RDP with the default port on local IP

2. Why implement a simple/weak password policy.

This is what happens when you get the school vice principal or a teacher who is good at connecting iPad's to WiFi also do CTO duties and make decisions.

Do whatever you want to do man.

This is why school's shouldn't have an "IT guy" to run the system.

And although it's a pain in the ass, just role back to your last backup and only lose the days work... riiiight?

I personally think it's OK if the IT guy can escalate issues.

Couple high schools up where I am employ a semi-regular IT guy for the mundane tasks, he has support from an outside contractor.

Edit:

I just remembered one of the IT guys is a student.... lol. Much of his time is spent fixing Chromebooks

my bet would be on this.

if the contractors 'who carried out a recent systems upgrade' actually left that 'temporary password', they shouldn't be in business.

pros worth their name should and would (normally) be well aware of these things. however, as secure as you can get your environment to be, you can't really completely guard against that click on a link from an email.

There is a difference between file shares on a server being encrypted, and the server itself is compromised and with due respect, who cares, it's an easy restore if it's just some file shares. What is much more of an issue, is the server OS itself being compromised which shouldn't be possible from any workstation.

Clicking a link on an email likely results in file shares being encrypted, this isn't as big of a deal.

in other words no one knows .
Just tell them something (anything) , then move on & fix it ?

The school hired information technology security experts to assist the school's technician investigate the hack and shore up the schools cybersecurity.

You'd think the school would do this before refusing to pay, not after.
