what mystery wire is this?

I'm helping a friend with some re-wiring projects from an older house. There was a wall socket that simply covered with a faceplate near the kitchen. We opened up the faceplate and saw this mystery wire.

Does anyone know what type of wire this is, and what it might be for?

House is 50 years old, only this single strand that we found (maybe 10 wires?). Makes sense, they would have a telephone close to the kitchen.

We will close it up to never use it again. Thanks!!!

cheap, fast, good - pick any two.

They used wire for telephone 50 years ago? Didn't know. I thought they used Echo or Google Home?

you don't even want to use it. and some people really want one.

a friend really wants an extra pair of wires for power a non-PoE router.

The "bundle" of "wires" is a cable.
Check with non-contact voltage sensor. There should not be high voltage (>40V) on any wire.
My guess is this is some kind of low-voltage wiring. Could be intercom as suggested by another poster. It does not look like twisted-pair to me (wrong colors, not common 50 years ago) or telephone (usually red, black, green, and white, 24 ga.).
If you remove the tape on the ends I bet you will see 20 ga. solid conductors. Typical low-voltage cable.

This is telephone wire from the 1960s-1970's, very common. Technically 'cables' generally have an outer jacket, this type of wire does not.

POTS phone lines register around 90VAC when ringing. A non-contact ac voltage tester will react to this voltage. Some react to things as low as 24VAC. The do not react to DC like the normal -48 vdc present on phone lines.

Cat-3 station wire (red, green, yellow , black) was commonly used in the 80's and 90's but since then Cat 5e has become more common.
