Mobile and Internet Security How to Defend Against Attackers
Telephone fraud is definitely not a new phenomenon, but the methods are becoming increasingly sophisticated. We have talked to an expert on how to avoid being fooled.
Mobile operators have their own large security environment that blocks hundreds of thousands of scams every year. As per security advisers and investigators of those firms.
– There is definitely no lack of ingenuity in the fraud industry. In order for the scam business to be profitable over time, they still have to adapt their methods. The attacks are continuously adjusted to the level of knowledge of the potential victims, while the scammers try to circumvent the technical security measures of the telecommunications operators.
The latter is far more difficult than manipulating people, so scam success is largely about how attentive we are when the scammer tries.
It may therefore be wise to know how the scammers operate.
The three most common scams – right now:
1. Local numbers enter into confidence
While we have gradually become more vigilant when calling from unknown, foreign numbers, the threshold is significantly lower when it comes to numbers starting with local country code.
During the summer, the security department of mobile companies registered that fraudsters have begun to imitate local numbers, with both nine and ten digits according to the country code.
In a busy day, you may not notice how many digits there are in the number. It starts with normal mobile number, so it’s safe to answer…
They receive daily inquiries from customers who report suspicious experiences with phone calls, text messages and emails from people pretending to be someone else. This is called “spoofing”.
– The scammers have started to abuse and spoof specific country phone numbers to a greater extent when they contact that country residents, both real and constructed numbers.
If your number gets spoofed, it is important to know that neither your mobile nor your number has been hacked. The scammers use software that allows them to pretend to call from a number that is not theirs. It also makes it very difficult to reveal the fraud to the person being contacted – before responding.
– It costs nothing to answer, but the potential for loss lies in what happens afterwards. Then the scammers will gladly try to clear you of personal information and card details.
If you find that someone has misused your number – contact your mobile provider so they can often help you. by blocking foreign calls from your number. But it also means that you cannot call from abroad to your country, e.g. when on vacation. The vast majority of smartphones can also block numbers that are bothersome or unwanted. If you do not recognize the local number that is calling you – spend a few seconds looking at the number of digits before answering.
2. “Microsoft Scams”
This is a classic example of “phishing”, where the scammer “fishes” your personal information. By accessing your PC, the scammer tries to get you to download malware, pay for viruses you don’t need – and get both card numbers and login details for, for example, online banking.
Mobile operators daily prevent and handle fraud attempts.
Here are tips:
– If you experience or suspect fraud attempts via calls or SMS, you can notify your mobile operator.They have the opportunity to block unwanted international calls before being forwarded to specific mobile subscriptions.
Neither Microsoft nor any other operating system vendor will contact you to request software downloads or provide sensitive information in this way. Therefore, in order to reveal this fraudulent method, it is important that as many people as possible know how it works. Knowledge is the most effective defense!
3. Interrupted calls pique curiosity
Have you ever been called from an unknown foreign phone number that only lets it ring once or twice before it goes silent? Then you may have been exposed to a scam called “wangiri”. It is Japanese and means that the call ends after just a ringtone.
The point is that you should not be able to answer, but be sufficiently curious to call back. It is only when you call back that the scam starts – the number you call back is an international high-tariff number with a high minute price.
As many as 10% who receive a “wangiri” call actually call back the missed call, so this is a very simple and profitable form of fraud.
– The international scammer uses a so-called call generator to call several thousand daily subscribers at once. Remember that the taximeter starts even if you do not hear someone answer at the other end, and it can be expensive in some cases, warns by security expert.
Be aware of which numbers you call back. If you do not recognize the number, or do not expect to receive a call from the country in question, you should not call back – no matter how curious you are.
You can’t stop all the threats yourself
The difference between scams and other types of digital threats is that you can often prevent the scams yourself, while you need help to stop or limit everything else that can happen.
Therefore mobile operators offers a number of security services that make the digital life safer. One of these is Secure ID, a fraud prevention service that helps you in the event of ID theft.
