Dangerous Email that’s Hard to Ignore

It may be tempting but you should take the time to question your Email before you open.
A common way computers are infected or compromised has always been a simple yet well thought out deception. It can happen to anyone and the use of social trickery is nothing new. Understanding the victim is all that’s needed to receive their cooperation. 

If you’re thinking it could never happen to me this refreshed couldn’t hurt. You might want to share the examples here with your friends, family and especially your employees. Social engineering has come a long way since the possibility of seeing Anna Kournikova naked.


Here’s a common example that has been used to infect computers with the crippling Cryptolocker extortion attack.

This one and variations are going to get more popular as Santa starts shipping his presents. In this example the “From” email isn’t even disguised which means these guys were really lazy. Don’t bother replying because the Email address belongs to someone who has already been hacked and was probably shut down by the time you receive your Email.

Any Email “bait” like this will appear to be a legitimate message. The attacker linked to text and a graphic located at FedEx. The simple line of code below is all that’s needed to display the FedEx logo

This Email from fake UPS is also tempting because you certainly wouldn’t want to miss anything. We all love packages.

Human Resources Needs You

Here’s one directed at employees designed to be a standard employment request. In this case, it’s to use the company car. It’s very common to see attachments that appear to come from Human Resources.

The “From” address and even filename has been doctored to make it appear to be from within the company. If the company is large or you’re a new employee downloading and filling in this form may not seem suspicious. It’s not unusual for an attack to be targeted since information on officers and HR managers is easy to find.



You’ve Been Reported

I’ve received a few claiming to be from Dun & Bradstreet trying to scare companies into thinking they need to clear their good name.

It’s also common to see fake Emails from the Better Business Bureau. In the U.K. there’s Companies House which registers and keeps track of companies for the Department for Business, Innovation and Skills.

Question Every Email

These phishing expeditions are common and effective in all countries. I generally question every Email even when it comes from someone I know. How many times have you received Email from friends saying they’ve been hacked? If you have any doubts just contact the sender or an official with the company sending the message. My bank has always thanked me for calling. They love to impress customers with their knowledge of security trends.


Curiosity Killed Your Job
It’s not unusual to receive messages which appear to be meant for someone else. More than a few attacks succeed because of human curiosity.

Speaking of curiosity, I’ll end with a newer version of a classic bait and steal scheme.

blog-email-intuit

I’ve worked for companies where discussion of salaries could be cause for immediate termination. An ancient method for infiltrating a company involved dropping an infected floppy disks labeled something like “Employee Salaries” in public places. This “Baiting” is still used but relies on DVD’s, USB Flash drive or SD cards labeled as personal or secure data. Visitors often have access to rest rooms in secure areas. What they leave on top of a towel rack could be more dangerous than high explosives.


I’m sure what I’ve discussed isn’t anything new but you may know someone who would benefit from this lesson. Share these examples along with  a healthy dose of paranoia.  The data you save may be your own.

Saving XO Screenshots to a USB Drive

and.. How do I copy XO files to my own computer? It took me a few days to learn how to do screenshots to post here. It’s really simple and this lesson will also teach you how to copy almost anything from the journal to a USB drive connected to your XO laptop.

Step 1: Get the screen you want and just hold down the Alt key and press 1. (Alt+1) This will create a screenshot.

Step 2: Go to back to Home and resume the XO Journal Activity. You’ll see a new “Screenshot”

Drag the screen shot down to the USB icon

Step 3: Plug in a USB thumb drive or other supported USB drive into one of the USB ports. You could actually do this at anytime but I wanted to split up the two operations. When your USB drive is plugged in you’ll see a USB icon on the bottom of the screen.

Step 4: Click on the Screenshot; drag it down and drop it on the USB icon. You can also drag down other data objects like photos or files created with Write.

Step 5: Hold the pointer over the USB device icon and wait until you see “Unmount” appear. Be sure to Unmount the device or the the screenshot file may be corrupted.

Be sure to Unmount your USB device

Step 6: Plug the USB drive into your other computer and use explorer to view your files. You should see “Screenshot.png” followed by “Sceenshot_1.png”,“Sceenshot_1_2.png” and so on. Most photo and imaging programs will read the .png format.
