How does ransomware get into major networks, such as schools or other large public agencies?
I read an article about ransomware affecting the public transportation service in Kansas, and I wanted to ask how this can happen. Wikipedia says these are "are typically carried out using a Trojan, entering a system through, for example, a malicious attachment, embedded link in a phishing email, or a vulnerability in a network service," but how? Wouldn't someone still have to deliberately click a malicious link to install it? Wouldn't anyone working for such an agency be educated enough about these threats not to do so?
I wanted to ask in that community, but I was afraid this is such a basic question that I felt foolish posting it there. Does anyone know the exact process by which this typically can happen? I've seen how scammers can do this to individuals with low tech literacy by watching Kitboga, but what about these big agencies?
Edit: After reading some of the responses, it's made me realize why IT often wants to heavily restrict what you can do on a work PC, which is frustrating from an end user perspective, but if people are just clicking links in emails and not following basic internet safety, then damn.
I'm in somewhat of a leadership position in an agency. I feel like I should talk to those above me about having more training for my co-workers. This is a nightmare scenario.
the way we deal with this in my org is testing our own staff... we use a service that sends very well faked emails. They can look like they are from our own vendors/staff even.. but they contain invalid links that an end user should know are not valid.. these emails are technically 'compromised'. when an end user clicks a link, they are informed they failed, and automatically enrolled in one of our mandatory security training classes. every time they click a bad link.
the best part is we silently rolled this out and something like 80% of c-levels failed. they were soooo pissed... but what could they do?
I've worked for places that do this, and I've seen the same people having to do the same training every time these emails went out. I feel like they never learned from it. They'd even get pissed that they had to keep retaking the training, but I feel like it never occurred to them that they should maybe change their own behavior.
No hr component, no reason for her to take it seriously except for the annoyance of the training. Give her a little scare and maybe she doesn't have to be terminated, or she's just an idiot.
Unfortunately a lot of companies treat IT as an annoying afterthought, so it isn't uncommon for there to be no real enforcement mechanism.
I don't work there anymore, but there were a lot of other problems with that place, so it doesn't exactly surprise me that there was no teeth in their policy
Wish you could get our IT to make ours good fakes instead of coming from "whatever@cityname.securitytrainingcompany.blog.com" or some shit. It feels like they're not even trying. Although I do work with one of the single dumbest people I've ever met, so maybe that's to give her the teeeeniest chance at identifying it.
Confirm dialogs are a perfect example of UI intertia.
You hit confirm on a close dialog so many times that it doesn’t matter what it says. By the time you’ve registered what it is muscle memory has done it’s thing
