The Bank Transfer Scam

Facebooktwitterredditpinteresttumblrmail

Dear tellows friends,

Bank transfer fraud happens more often than you can imagine. Fraudsters imitate various offial organisations, including banks, to persuade you to move money out of your account and into their hands.

Scammers use manipulative methods to panic real people into handing over their money and details. Perhaps you receive a call or text telling you that your account has been ‘compromised’ and you need to move your money somewhere ‘secure’. Maybe you have to click a link inside a text message or email and log in to your online banking account to stop a transaction. Of course such messages are more often than not fraudulent, but they can look very realistic. Links in text messages may take you to a spoofed albeit realistic version of your bank’s website, making the fraud almost more believable.

Updated 24 Feb 2020

It is almost March, how time flies! The tellows team has also been busy keeping the information about phone scams up to date. As expected, unfortunately, the number of spam calls, especially related to cost traps, is soaring because of more advanced technology nowadays and scammers having more means to escape from the authorities. Scammers have been taking advantage of taxpayers in last year. According to HMRC, over 100,000 reports of frauds were reported last year and the number is increasing. Last year, HMRC announced that it has been working with Ofcom, Mobile UK, Mobile Ecosystem Forum and Telecommunications UK Fraud Forum together to prevent bogus tax calls. The cooperation was successful and 1050 numbers have been deleted by HMRC, of which many numbers started with 0300. HMRC also stated that the number of phone scam reports has reduced by 25%, which is a very promising sign.

The New iPhone Update is Here!

Facebooktwitterredditpinteresttumblrmail

Dear tellows fellows,

We are happy to announce that tellows has released a new update of our Caller ID & Block App for iPhone with brand new features! In the new version, it’s now even easier for you to protect yourself from nuisance calls. As you probably already know, the tellows app can help you to find information of telephone numbers all over the world. We have finally created new features, such as free real-time identification and automatic update of the caller ID, so you can enjoy even more benefits, free of charge! So which are the new advantages you can get after the new update? Check it out below!

  1. tellows Score Display on Incoming Calls

The so-called Lite version of the tellows protection, which is the free version where users won’t be charged at all, now offers automatic identification on any incoming calls. The tellows score will be displayed on the incoming call, indicating the potential risk of the call. The score 1 means that the number is trustworthy, whereas score above 7 refers to potential risk of the number. With this new feature, it’s even easier for users to decide whether they should pick up a call and whether the number is possibly dangerous or not.

  1. More scores – more details!

From now, your phone will not only identify dangerous calls. You will also benefit from information of positive rated numbers, such as trustworthy companies or service hotlines. The new app version will identify numbers from score 1 to 9 to provide you with more information for better security.

Cross-devices Blacklists for Registered tellows Members

Facebooktwitterredditpinteresttumblrmail

Dear tellows followers,

more and more frequently consumers are victims of telephone spam or frauds, or are simply provoked by frequent unwanted calls. They use various tricks to pull our money out of our pockets. Here in our community, many phone owners report and rate the numbers that called them, sharing their experiences with other users to protect you and themselves. This works in an easy and uncomplicated way.

The heart of us is the tellows score. It is calculated from all previously stored ratings for a specific phone number. Users of the community can report and rate phone numbers on a scale of 1-9, where 9 means that a very dangerous or very annoying phone call is on the line and 1 is a rather harmless one. So you can rate and categorize each phone number on a scale from 1 (trustworthy) to 9 (dubious). From 7 on, the corresponding phone number is placed on a blacklist of the community and is thus blocked for everyone using the tellows products by itself and provides an appropriate protection. Depending on the rating, you can then assess the seriousness of a called number. In this way you can inform yourself online about the experience other users have already made with the respective number. And if there is a cost trap or telephone fraud behind it, you can know it because of the negatively rated number before they call you back again. Additionally, you can create your personal blacklist and add unwanted numbers that are not yet rated or don’t appear in the blacklist. If you rate a number negatively, it will be added to your personal blacklist and will be blocked the next time you receive a call. Even if the overall rating assigned by other tellows users of the phone number is different, it will still be blocked.

In order to be able to benefit from the collected assessments and experiences at an early stage, for example even before a call is answered, the successful tellows app for devices with Android or iOS was developed. This already indicates during the ringing, how trustworthy the calling number is by using the reports of the community. Thus, when the call is received, the tellows score is displayed.

French University Project with tellows API

Facebooktwitterredditpinteresttumblrmail

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.
