⬅️ Curl-impersonate: Special build of curl that can impersonate the major browsers

There's a fork of this that has some great improvements over to the top of the original and it is also actively maintained: https://github.com/lexiforest/curl-impersonate

There's also Python bindings for the fork for anyone who uses Python: https://github.com/lexiforest/curl_cffi

I'm rooting for Ladybird to gain traction in the future. Currently, it is using cURL proper for networking. That is probably going to have some challenges (I think cURL is still limited in some ways, e.g. I don't think it can do WebSockets over h2 yet) but on the other hand, having a rising browser engine might eventually remove this avenue for fingerprinting since legitimate traffic will have the same fingerprint as stock cURL.

Did they also set IP_TTL to set the TTL value to match the platform being impersonated?

If not, then fingerprinting could still be done to some extent at the IP layer. If the TTL value in the IP layer is below 64, it is obvious this is either not running on modern Windows or is running on a modern Windows machine that has had its default TTL changed, since by default the TTL of packets on modern Windows starts at 128 while most other platforms start it at 64. Since the other platforms do not have issues communicating over the internet, so IP packets from modern Windows will always be seen by the remote end with TTLs at or above 64 (likely just above).

That said, it would be difficult to fingerprint at the IP layer, although it is not impossible.

Wait a sec… if the TLS handshakes look different, would it be possible to have an nginx level filter for traffic that claims to be a web browser (eg chrome user agent), yet really is a python/php script? Because this would account for the vast majority of malicious bot traffic, and I would love to just block it.

I'm always ambivalent about things like this showing up here. On one hand, it's good to let others know that there is still that bit of rebelliousness and independence alive amongst the population. On the other hand, much like other "freedom is insecurity" projects, attracting unwanted attention may make it worse for those who rely on them.

Writing a browser is hard, and the incumbents are continually making it harder.
