Is it Suitable for Giant-scale Tracking?

We describe a monitoring approach for Linux units, exploiting a new TCP source port technology mechanism lately launched to the Linux kernel. This mechanism is predicated on an algorithm, standardized in RFC 6056, for boosting safety by better randomizing port selection. Our approach detects collisions in a hash function used in the mentioned algorithm, based on sampling TCP source ports generated in an attacker-prescribed manner. These hash collisions depend solely on a per-system key, and thus the set of collisions types a device ID that allows monitoring gadgets throughout browsers, browser privateness modes, containers, and IPv4/IPv6 networks (together with some VPNs). It may well distinguish amongst units with an identical hardware and software program, iTagPro locator and lasts until the device restarts. We carried out this method after which examined it using monitoring servers in two completely different locations and with Linux gadgets on numerous networks. We additionally examined it on an Android device that we patched to introduce the new port selection algorithm.
