How to protect yourself from Scam Calls in Australia

We’ve all seen spam and fraud in our everyday life. Luckily, it is often easy to see through them before it is too late. But especially on the phone, it can be tricky to distinguish a genuine call from a scam call. On we receive reports about scam callers everyday. The users may ask themselves, why is the person calling me? The caller already knows my name and address, so it has to be trustworthy, right? – No way! We tell you what common frauds look like and how you can protect yourself from them.

Scam Losses Rise

In 2021 Scamwatch reported, that losses exceeded $211 million in the phone scam area between January and September. This numbers is even higher than it was for the whole year 2020. In 2021 Scamwatch received over 113,000 reports about phone scams.

Less people reported losing money in 2021. On the other hand, those people who lost money, have lost larger amounts with an average loss of $11,000.

Common Types of Scams

Scammers like to tell stories and make you believe that the call is urgent by putting pressure on you. For example there is a time senstitive event with only limited offers left or your safety is at risk when you don’t allow access to your computer or pay a debt immediately. Sometimes they pretend to be from well-known company or your insurance. Maybe you also receive a text message or a silent call where you have no chance to even answer the phone. These are just some tricks Australian scammers use to make you call back and share sensitive data.

It’s very concerning to see these scams evolving and becoming more sophisticated to steal even more money from unsuspecting people. – ACCC Deputy Chair Delia Rickard

How has the Covid pandemic affected telephone spam worldwide?

We have been living with the restrictions that the Covid19 virus brings with it for six months. The time cuts are different in many countries and regions. The economy around the world is severely affected by the effects and regulations of the government. But how has calling behavior changed during the pandemic?

Fewer calls in lockdown

Almost every company needs the telephone in everyday life, regardless of whether it is for daily customer support, consultation or appointment arrangements, or sales and acquisition. Due to the restrictions in daily work and the increase in home office activities, the number of calls has changed in many places. Many companies have not only moved their work home, but have been forced to severely restrict business lines.

This is reflected in calling behavior, which has changed significantly during the pandemic and especially during the strict lockdown. External telephony was greatly reduced, not only because other companies were less accessible and technically poorly equipped at home, the economic situation also meant that appointments, support or expenses through sales and collaborations were not made or were limited until further notice. This also applies to call centers and companies that use phone calls for undesirable purposes such as telephone spam, advertising or even fraud.

tellows shows the history of caller activity in different countries

Even on tellows we experienced fewer reported calls and fewer numbers were searched, which is noticeable in the low number of calls made in general.

In the following diagram, we show you the caller behavior over time in the UK and France.

The 7 biggest myths about telephone scam and Co.


Dear tellows-fellows,

Superficial knowledge can be dangerous, we all know that. In terms of telephone advertising and fraud, it can cost you a lot of money and nerves! Therefore, today we present you the most common myths regarding telephone advertising, telephone fraud and possible manipulations on tellows and clearify them.

1. Telephone scam only affects older people

As soon as one hears of telephone scam, one has more in mind the 93-year-old Mary-Ann, who was tricked by fraudsters, than the 26-year-old computer science student Stella. The fact is: Fraudsters often try to scam older target groups since they tend to be less careful and easier to be fooled. They are not always informed about the latest phone scam tricks, so a call from an alleged family member or the bank employee can turn into a costly trap.

However, this does not mean that everyone else can think themselves safe. Since there are many types of fraud, the victims differ. There are even tricks that mainly lead to success for the fraudsters among younger people. Such an example would be the Microsoft support scam, which targets access to sensitive data from their victims on the phone. According to Microsoft, this stitch is particularly successful in the age group of 18 to 34 years.

2. As long as I don’t give out any data about myself, I can’t lose any money

Unfortunately, this is also a misconception. It is true that you should never reveal your data on the phone, but there are other ways to get your money. Ping calls pose a great risk here. In this case, the fraudsters ring only a few seconds to provoke a recall. If this is done, a high fee will be charged, as the numbers are often foreign and you will be drawn into a waiting loop that can cost you a lot of money per minute.

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,, 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.
