Tech Support Scam Returns with a New Trick

Dear tellows fellows,

as you might remember, we have posted an article about fake technical support scam in the beginning of last August to warn you of the rising issue of a Microsoft scam. Microsoft has also released several statements on their official website to warn people about this fraud. Unfortunately, this doesn’t stop scammers from finding other ways to trick people.

Recently, we found out that many fake tech support scammers have been using another method to deceive Microsoft users. They take advantage of Microsoft TechNet portals and created over 3000 fake pages. The TechNet portal is usually used by Microsoft users to save documentations of products and images as well as to offer community forums for its users. Unfortunately, the scammers have found a way to use the subdomain of TechNet portal, gallery.technet.microsoft.com, in order to be displayed on Google. Although the pages are usually blank pages with error message, the scammers’ purpose is to display their phone numbers on the headline of the pages. They mostly affiliate the tech support with Bitcoin or Coinbase Helpdesk. The problem has gotten bigger, as the fraudsters were able to rank quite high on google search and their fake pages were displayed on the first page when the users search for keywords such as “Helpdesk Microsoft”, “Helpdesk Coinbase”, etc.

Introducing Our New Rating Box

Dear tellows fellows,

Our community is changing and developing every day. We always take our users’ suggestions and ideas into account, in order to make tellows a better platform. Therefore, we have developed some new features to make the tellows community even more helpful and effective than before!

Therefore we have developed a new feature, so that you are able to rate a phone number without writing any comment, especially if you think that there’s no necessary information you can share.

French University Project with tellows API

Dear tellows fellows,

tellows is versatile and the tellows data can be used for different systems. We developed an API that suits all kinds of projects and allows you to access the database and use the number details as preferred.

Today, we want to introduce a student project from the UPMC University in Paris, which was realized with the help of the tellows API.
For the students, the task was to build an Android App with an API. The idea was to develop a caller ID that identifies French numbers and shows whether a number is dangerous or trustworthy. With the help of our API, they managed to build the App in just a few weeks. As soon as a call comes in, it shows the respective tellows score that indicates if the number is dangerous or not. Opening the app, it will show a list of all recently received calls. Furthermore, it displays the number, score and country.

The final result was presented within the class and turned out successful. We are happy that we could be part of it and help to realize the project. However, a publication of the application is not possible.
