I am totally new to Signal messenger. I have just received a contact request, without a text, and just with a bin file of 13 KB in the attachment. I do not know the strange nickname which is 4-letters short, with a capital letter at the beginning and which does not give you any hint of a meaning.

I do not know the phone number, though it is at least a number of my country, and I would not be astonished if someone just tried to connect when I am new there.

Main question: How should I react to this?

Sub-questions could be:

How can I ask this person back to explain who she is without accepting the question to connect?

Or if I need to connect for this purpose:

  • can the bin file be dangerous and
  • is the mere contact already possibly revealing something personal about me that I do not want to share with any marketing or whatever bot?

Ignore and delete this contact.

"bin"-files under Linux, macOS and iOS are the same as "exe"-files under Windows. It is probably malware.

The helpful comment brought the answer.
