I'm going to go out on a limb here, and say that I can see some affiliated colors here.

On the right, you have Orange and Yellow, but for my color scheme to work, let's call it "light orange". So, Orange/Light Orange.

Then, the navy blue and lighter blue is another pair, and I'm calling it Blue/Light Blue.
Then, Brown and a pinkish tan one, which I deem "light brown." => Brown/Light Brown.
Finally, Grey, and white, which is the lightest shade of grey. => Grey/Light Grey.

I would map the Orange pair to the Orange pair, Blue with Blue, Brown with Brown, and the Greys with Greens. Hopefully, that's how they're paired in the cable, as I cannot see that in the picture, but I can make an educated guess.
I can also see they probably used the blue pairs for pins 4 & 5, the brown for 3 & 6, the orange for 7 & 8, and the grey for 1 & 2. But if you're going to re-crimp, use my color mapping.

Also of note, category rated cables have a set number of twists per inch. Generally speaking, the more TPI, the higher the rating, and the lower the electro-magnetic interference, which means higher throughput.

YOUR CABLE might not have enough twists to even reach 100mbps, please be aware of this.

That cable most likely does not meet specs for Ethernet.

That said, you could try to use it, and it might work (or it might not)

Use whichever pairs you like, but be sure you use the same set at each end of the connection, and that each pair corresponds with where an Ethernet pair should be.

This page has an image that shows which pairs go together:

If it seems plausible, I'd use it to pull through a real Ethernet cable if it seems like it will move easily

Apparently an old-style French phone cable. For phone uses, it is:

1 grey

2 transparent/pink

3 white

4 brown

5 blue

6 yellow

7 purple

8 orange

Looks like that pairing is unsuitable for Ethernet, so I'll use something else.
