Anton Ponomarev, director of ESET’s corporate business department in Russia and the CIS, warned the Russians about this. According to Ponomarev, often users do not take pictures of their personal data, they close their location data, contact list and other sensitive information from applications. But most underestimate the risk of malware plugging into the microphone and eavesdropping on the victim.
You can understand if your device has hacker applications by looking at the settings of your smartphone. If you see that an application without an icon or with an unknown name has access to the microphone, this is a clear sign of spyware.
“Often, for security reasons, users do not take pictures of their personal data, for example, passport numbers, bank cards or PIN codes, but in some situation they can say them out loud. Leakage of such information allows fraudsters in a matter of minutes to carry out illegal transactions with finances, as well as unauthorized actions to register in certain services on behalf of the victim, ”the expert explained and urged users to be more attentive to this moment.
