What is ransomware?
“Ransomware is a malicious software that is installed on your machine or your network. The machines on your network, they encrypt all of your critical files. They don't encrypt the operating system because that would ruin the machine, but they target document types that users use across all kinds of industries. When they're encrypted, the keys are not kept on the machine. The keys are encryption keys, which is what you need to decrypt them. The attackers have those offsite somewhere and what they'll do is they display a note on your machine. When it's done encrypting, it says if you want to get your files back, it's going to cost you this much,” said Christopher Brenes.
“It's typically Bitcoin and so you have to arrange to purchase Bitcoin. It's anonymous. It goes out to the ether and you lose track of it and you've made a payment to some anonymous attacker somewhere,” added Brenes.
When Shouldn't I Open Emails and Attachments?
“Anytime that you think there's something going on that seems a little abnormal. It could be who it was sent from. The email address looks correct, but the domain is not quite right. It could be the time of day that it was sent that's a little bit abnormal. Three in the morning when you're used to not getting emails from that person at that time. If it contains an attachment that's not relevant to a typical communication string or to your role within the organization, don't open it. If it says payroll report and you're not in HR, don't get nosy. Curiosity killed the cat, it also kills the network,” said David Spire.
“Email attachments commonly can hold malicious payload, so you don't want to open those. It used to be that you didn't want to click on any dot exe. Nowadays, they'll put that malicious payload on Microsoft Word documents, PDF files, any kind of file. Beyond the attachment, they've become much more sophisticated where they're embedding malicious payload in links. Just click a link, the emails look incredibly realistic. Educate people on what to look for, question everything. If you do think it's legitimate but you believe there's a shred of concern, always communicate out of the band with that person. Make a call or shoot a text message, hey, did you really send this?,” added Spire.
Should I Use a Password Manager Program?
“Password managers were designed to help keep passwords secure and help use different passwords across different applications. You should absolutely not reuse passwords. There was an article that came out two days ago of a hacker that just got out of prison. He spent 17 months or so there and he said his number one favorite thing was password reuse because when he learned your password, one application, he would take that out and he would try it against banking sites, Facebook, LinkedIn, anything you could think of where he could get additional information or additional passwords. Password managers allow you to very easily create complex passwords. It stores them for you where you can use them from any device, which makes it convenient,” said Christopher Brenes.
“I absolutely believe in password managers. I happen to use LastPass myself and I'm not affiliated with LastPass in any way. There's plenty of good ones out there. When you put all of your passwords into a single spot, you suddenly have a very large vulnerability if it gets compromised. Don't use one unless you back it up with what we call two-factor authentication (2FA). That's going to give you an added layer of protection,” added Brenes.
