How did the bank know where I was surfing the Internet?

Question

Information Security

This morning, from the phone, through the mobile network, I google information on opening an IP. Opened a couple of sites in the issue and closed. After 5 minutes, a girl calls, pretending to be Alpha Bank. Calls my full name, says that they received an application for the opening (or consultation, did not understand, but not the essence) of IP. For questions about what kind of application, where exactly it came from, etc. says something unintelligible and avoids answering.

Naturally, I did not leave any applications, and I am not a client of their bank.

The question is simple: what the hell is going on?
I think there was no application, but how did they know who to call and full name?

Answer 1

Some organizations (usually content providers) enter into an agreement with mobile operators. When visiting the provider's site from a mobile phone, the operator also sends the mobile number to the site (in the request headers). After visiting the site, the site owner knows which pages of the site the user visited and his mobile number. Your full name is not given, but in the case of banks, they may have their own database with a link to the number and full name.

Answer 2

Calls my full name, says that they received an application for the opening (or consultation, did not understand, but not the essence) of IP.

Are you already a client of this bank? If not, then the first question should be - where did you get my number and personal data protected by the law on personal data. Further on the situation - the contacts of the management, if it is really a bank, a call to the police if the phone was hung up with a statement about an attempted fraud.

Answer 3

now you understand why there is so much noise around "data protection", "right to anonymity", GDPR and so on?
With a sufficient amount of data collected, it is not a big problem to understand who and where was. And you are also logged into social networks on the same phone.

Answer 4

it’s still flowers, I had such a moment: I
called to rent an apartment, after which advertisers call me for several days and offer to buy an apartment, one of the advertisers explained that the provider sends information to them by keywords, with a name and an encrypted number, i.e. . they see the name, the topic of interest and the call button, they don’t know the number itself, as they explained to me, but to my request to remove it from the database, they agreed, noting that they were not interested.

Answer 5

bank

spoiler

(если это конечно был банк - а то мне опять сегодня звонил "финансовый мониторинг Сбербанка", я был не в настроении, наорал на девушку и послал ее в жопу :D )

this information was leaked by a mobile provider - he most likely has a contract concluded - as soon as a ready client appeared - immediately merge the information there. To look for something more serious than Lena Vasilek's songs from the phone is to expose yourself to trouble :)

Answer 6

Sorry my answer was removed. But in general, at the moment, I would recommend going to check yourself in the role of the director of some company, the owner of an EDS, etc. I'm serious.
You are in this world, like an open book, it costs nothing to get general information about you, and if necessary, buy it from someone. In addition, data storage implies their possibility of theft / “theft” / transfer of rights. For example, comrades from free WiFi networks and networks in cafes quite openly collect and leak data. Surprisingly, there are a lot of things going on.
Among other things, you are already an adult guy and obviously showed your passport more than once. In a bank, for example, when opening an account. All this is stored and used. In some cases, including dishonest employees. It is foolish to believe in the honesty of the whole world, but not everything can be dealt with, you need to check.
In general, from my practice, banks are in no hurry to call upon opening, if you yourself have not done something. VTB, for example, sent me an offer only half a year later, even more like, I don’t remember exactly. The rest did not pull themselves up) So maybe you yourself in your blind delirium called Chota.
UPD: government agencies, including the tax authorities, also leak data to banks, for example, when registering an individual entrepreneur, LLC. Even before they get into general sources (there is a difference of up to a week, no more).

Use a browser with tracker blocking and an ad blocker. Not a panacea, but it will reduce the risk of such jokes.
Firefox + uBlock Origin for example.
