Social Engineering / Hack attempt

Today I received a phone call at 5:24PM (CST) from (281) 593-3503 showed up on caller ID as Cleveland, TX.

This is the 2nd call from this person, who had a strong foreign accent. The first time I received a call from him, I told him I wasn’t interested and hung up. This time I was bored, so decided to go along with him.

Here’s how the conversation went:

He started out by telling me he has been monitoring infected files on my computer. He then asked me is my computer connected to the internet.
I said yes.

He asked what I seen on my screen, I said google

He asked me to close the window and press <windows/flag> key and “R”, I complied.

He asked me what I saw, I told him the run screen.

He asked me to type “inf hiddenfiles” then asked me if I knew what it was, I said no. then pressed enter after he instructed me to.

This opened a window

He then asked me if I knew what these files were, I said no.  He said that they were a list of infected files. These are infact driver information files (windows/inf)

Then then asked me to go to a website by way of <win/flag> + R (run command) ( http://rescue12.webs.com )

Then he asked me to download teamviewer and install it on my computer.  Since There was no way  I was going to give him access to my computer, I went ahead and pulled the plug.

I asked him, since he seen infected files from my computer, what was the IP address of my computer.  He didn’t have an answer.  I then asked him who my ISP was, he didn’t have an answer… I figured I spent enough time of the phone with this idiot… so I told him I knew what he was up to and was reporting it to the authorities.  He said go ahead, then hung up.

Now, here’s some relevant data for us geeks:

Who is for the website hosting the probably viruses:

I’m not being paid to do this, so I’m not going to load the files and see what wireshark shows… and perhaps trace the IP, which I would assume would be in a foreign country.

Bottom line everyone… if someone sends you links and they don’t look right… double check before you give anyone remote access to your computer. It is extremely easy to gain prolong access to your computer if you just give me 10 secs of remote access to your computer. If you get a phone call from your ISP (cox or centurylink) then perhaps it may be a legitimate phone call, but VERIFY.

I also asked for a call back number, and he gave me: 201-234-4604, I did not try to call it.

MAC OS X on a PC

Going to high school in the mid 90s, computers wasn’t as modern as they were today. Our school was 97% Macintosh, 2% Apple IIE, 1% PC. These were the old Mac II’s I believe. There was only 1 PC that had a modem and hooked to a phone line, so I stayed in that room. Since then, I didn’t look back and over the years seemed to forget about the Apple OS. Over the past couple of years, I noticed an increase in Mac purchases. Many friends who were tired of spyware and viruses, made the move away from Windows to the Apple world.
Everyone always asks me for help with their computers when things go south; 100% of which are all PC issues. Never had an issue with Apple. Recently posted an ad on Craigslist asking if anyone had an old MAC computer they wanted to get rid of. One person responded, stating that he could install OS X on my PC. I had heard about this some time ago, ago and hadn’t yet gave it a shot. So, last week I installed OS X on an older Dell GX270 (P4). Seems to be working nicely. The whole purpose of this is to learn a new OS in an attempt to broaden my knowledge in the IT world. Although I’m sure in the corporate world, Apple doesn’t quite have the grip that Microsoft has.

A+ Certification

Recently finished my degree, and have started studying for my A+ certification.  While finishing up my degree, I discovered that the Air Force will pay $4500 dollars to take classes for certifications.  Further research revealed that the Air Force offered free training CBT’s (Computer Based Training).  These CBT’s cover A+ and Network + just to cover a few.  My goal is to be certified on A+, Network+ and Security+ prior to me getting out of the Military in 4 years.  The only thing the Air Force will not pay for is the test fee’s.

Ahhh… I’m thinking about loading the latest Sabayon Linux on these… Luckily they’re double sided/double density!!!…


modem

Acoustic Coupler

Although I never used an acoustic coupler, I do remember the 300 baud modem I first had with my Commodore… all the good ‘ole days…. When I got my 14.4k baud modem and an IBM… you couldn’t tell me nothing.

Anyway, was going through the stuff I have here in storage here in VA. I really need to clean out the closets… I picked up the Commodore cartridges somewhere… don’t remember where. Probably a yard sale. The acoustic coupler I got from a buddy quite some time ago.
