Ransomware

There is a new threat that is literally holding Facebook and LinkedIn users hostage.  This threat is a new type of Ransomware called ImageGate.

What is Ransomware?

Ransomware is a kind of malware that encrypts the files on your computer, and demands a ransom to unlock the data. Users are faced with the choice of losing their data, or paying the attackers. Ransomware has been the biggest computer threat of 2016. Many security experts believe it is set to increase exponentially during 2017, due to using new methods of distributing the Ransomware.

How does Ransomware work?

Have you ever zipped up a file to make it smaller so you could send it to someone? That is similar to what Ransomware does when it encrypts your files. Your files are put inside of a special type of password protected file and it makes the unreadable, unless you have the password. Here is the hard part.

What does this have to do with Facebook?

This ImageGate exploit allows the hacker to add a piece of code to the information contained in an image file. This image is then loaded to Social Networks like Facebook and LinkedIn. When you click on the image in Facebook it asks you to download the picture to view it. When you download the picture it runs the script contained in the image, which starts going through your files encrypting your Pictures, Word Documents, Excel Spreadsheets and other types of files that they are targeting. Now your picture of your kids first Christmas has been replaced with a file that you can't open, but there is a message attached that tells you to pay the ransom if you want your files back.

How do I protect myself?

Be very careful while using Facebook or LinkedIn if any thing seems to be behaving differently Don't download files from Facebook....Ever Always think before downloading a file from anywhere Always have good Anti-Virus Always have a backup Use Facebook from your phone or tablet - there is usually fewer files to lose on your phone or tablet

Can I Get Ransomware other ways?

Ransomware has historically been spread via email, but we are starting to see occurrences using Social Media, Infected Ads, and Infected Websites. This is what has the security experts concerned that it will soon turn into an epidemic.

I have Anti-Virus, so why do I need to worry about Ransomware?

Don't get caught in the trap having a false sense of security because you have anti-virus. Most anti-virus products don't detect or stop Ransomware. These 2 reasons are why Ransomware is so dangerous. Technically, Ransomware is not a virus. It does't install anything or change any settings. It just runs a script that encrypts your files. There are some anti-virus vendors such as BitDefender which have developed what they call Ransomware Vaccine. This vaccine disables some of the common methods of running the scripts.

In Summary

Ransomware is a real and very scary threat to your information. You should:

  • Be cautious
  • Don't download anything unless you are 100% sure that you need it
  • Use your phone or tablet for accessing Facebook or LinkedIn

I am sure that most of us will at some point be on Facebook in the coming days and weeks. Please be careful while you are online during this holiday season. You don't want to have all of your files held hostage just so you can see a video of the dancing elves.

Testimonials

 

Ultimate It Guys has been the Cameron Housing Authority’s IT company since 2017. I couldn’t ask for a better one. The staff is quick to help & very professional. They will work with you until your problem has been solved. We will definitely use them in the future.

Cameron MO Housing Authority

The Nevada Housing Authority has been doing business with Ultimate IT Guys since June 2016. Prior to that time, we struggled with good tech support and did not have anyone in house capable of taking on that responsibility. We have had a very positive experience with Ultimate IT Guys and their tech support staff.

They make themselves available anytime for the support and training needed and keep us with the most recent updates. I have enjoyed the webinars and now have access for myself and the staff to those webinars that we miss. The value for the service provided by Ultimate IT Guys is worth a look at for your agency. You will find them customer service driven, have the ability to problem solve and easy to communicate with.

Hi I am Joan Wright, I am the Executive Director at McGregor Housing Authority. I have been with Ultimate IT Guys since 2017.

We are from a small community and we just don’t have much for computer support in this area. I met him at Texas Housing Association and he has done a wonderful job for us. His service is 24/7, all I have to do is pick up a phone and call him. One of his support staff is always happy to work with us. I have all my faith in Ultimate IT Guys they do a wonderful job.

Joan Wright

McGregor Housing Authority

We have been very pleased and impressed with the services and product advice we have received from Ultimate IT Guys.

They provided a big picture view of our business risk, then broke it down into actionable details through the assessments and the reports they provided to us. All very professional and informative but still in layman's language in a way that anyone can understand it.

Ultimate IT Guys have truly been a big help to Trinidad Housing Authority for the past 5 years. From keeping our computer systems up to date and virus free, to their excellent customer service. When we have an issue with our computer software or hardware, there is never a wait and they are always there to help, and at very reasonable prices.

I highly recommend the Ultimate IT Guys to anyone who needs IT support services. They have consistently given us excellent service at a reasonable price.

They know the needs of PHA’s, and are particularly well suited to filling the IT needs of housing authorities who are not large enough to have their own in-house staff. They can do virtually all the work they need to do remotely, so there is no waiting for an IT tech to show up. Our experience with The Ultimate IT Guys has all been positive, they have been a pleasure to do business with!

I am very pleased with the service Mr. Davis and his team at Ultimate IT Guys provide. He is professional, thorough, and supports our industry with a high degree of integrity. He is available and has always helped me with IT problems in a timely manner. I feel I am very knowledgeable about technology and could do some of the same tasks Mr. Davis performs, however it is beneficial to me that my staff can call him with issues so we can be more productive and focus on housing needs instead of computer/technology related issues and back-ups.

I would highly recommend Mr. Davis and his company.

Thank you,

Kimberly Gholson
