In the past month we’ve been reminded of the progress online criminals are making in their work. We’ve been working on two significant breaches. Just wanted to give you a flavor of what’s going on so you can remain vigilant with your email.
Harder to Detect
Both of these attacks started with “spear phishing” attacks. We have moved way past the Nigerian prince who has “millions of currency” to send to you if you just send him all your banking information. Oh, ya, gone, also, are the days of incorrect grammar and awkward word usage. In both of these attacks, the attackers had specific information about the sender, the recipient, and used proper English.
Case 1: Ransomware
In this case, the recipient thought he received an email from a friend with a link to an ESPN article about the NCAA basketball tournament. The article was real, but the page was fake and when he loaded the page the attacker dropped “ransomware” on his computer. A day or so later a message popped up on his screen that is his hard drive was encrypted in that he had to pay ransom within 48 hours or the price would go up. He paid and got his data back.
Ransomware Remained After the Attack
After he got his data back, we looked into it and found the email had not come from his friend even though it had his friend’s name on it and the website it sent him to was not ESPN. We also found the ransomware was still on the computer, just waiting to be used again by the attacker.
Case 2: Re-Routed Payments
In this case a vendor’s customer received an email that appeared to be from a known accounts receivable person at the vendor. The email referenced a specific bill the customer already had for close to $150,000. The email asked them to wire the the money to the vendor’s new bank account and included the relevant information. Since the email came from a known person and referenced a real bill the customer sent the payment to the new bank account. When the real vendor called to ask about the payment it all became clear and, to no one’s surprise, the bank account the money had been wired to was empty.
In this case, the attacker got a hold of the customer’s email, found the bill, set up a website and email account one letter different than the legitimate company’s email, and sent the request to reroute the payment.
All of this is just a reminder that anyone who uses a computer is actually one of the most important parts of keeping criminals out of your business. Stay vigilant and be suspicious of anything you receive by email, especially if:
It’s about money.
It’s about something urgent, like this offer expires in 12 minutes, breaking news, or current events
it’s about something emotional, like abused animals, bullied children, etc…
Where are they getting this kind of information? In many cases, they’re not hacking email accounts like they did a few years ago. Lists that include you, people you communicate with, people who are your friends on social media, and your emails are highly prized by both legitimate and illegitimate businesses. And, therefore, are big money makers for social media sites.
Ever clicked “Like” on one of those, “Can get 10,000 likes for beating cancer?” Or, for losing weight? Or, for whatever Facebook posts? Chances are good that a list including your name and your email and your friends’ names and emails, and everyone else who clicked “Like” and their friends is being collected and sold.
What can you do?
You can check to make sure that the email at least came from the right person and not some random email address. Many desktop/laptop email programs are set up to show you the email address it came from in the address box right next to the sender’s name. If it does show it then you can usually right-click on the sender’s name to get the email address it came from. It’s not foolproof but will expose many attackers. When the email name says it came from your friend John but the email address says it came from powereater@yahoo.com, you can be pretty sure it’s a scam.
The same thing is possible on mobile devices but how you do it is different on each phone and app.
You can, also, contact the sender and ask if they just sent you an email.
