Many users complain that calls from unknown numbers have become more frequent lately. Often these are representatives of various companies promoting services, or fraudsters who call themselves bank employees. People are surprised, because they think that they have not given their number to anyone. However, spammers buy such databases from third-party services, whereas earlier this required “stealing” from operators. Even some people anticipating a trick can be “caught” by spending on unnecessary goods / services or even trusting a fraudster. This is partly due to the psychological effect, because there is more trust in a lively and polite interlocutor in the tube than in the same questionable e-mails or SMS.
In modern times, subscribers are forced to leave their data almost everywhere, even when placing an order for pizza with delivery or buying goods in an online store. Some are engaged in collecting databases from open sources, and then selling them to spammers and scammers. Sometimes these “summaries” contain other information about a person, including his social networks and even passport data.
Now the easiest way to protect yourself is not to be gullible and not take it at face value when the caller imposes something or asks for personal information disguised as a bank employee. If spammers are pestering you, it is enough to politely say goodbye and immediately hang up. Some applications can evaluate an incoming call by checking the number against the bases and immediately give information about who is on the other end of the line, Androidinsider reports.
