How to defend against adblock detection/adblock subscription leaks?

Posted on by

Is there a best practice (or useful extension) for defending against adblock fingerprinting techniques? I’m not asking about how to bypass adblock detection as such, but rather how one might appear invisible (or spoof one’s i… Continue reading How to defend against adblock detection/adblock subscription leaks?→

Why don’t ISPs filter on source address to prevent spoofing?

and based on those answers, ISPs ignore it because of the overhead of checking for spoofing.

But that question is a bit old so I wanted to check if any development has been happening?

I just don’t understand why it’s so hard for ISPs to implement the first hops to check if the source IP is valid and record the given IP by the DHCP server for checking the validness of the IP? how can it be a big overhead?

For example, if someone starts spoofing a lot of IPs and does malicious activity like DDoS, will major ISPs detect it or they still don’t check?

Jeremy Hong: Weaponizing the Radio Spectrum

Jeremy Hong knows a secret or two about things you shouldn’t do with radio frequency (RF), but he’s not sharing.

That seems an odd foundation upon which to build one’s 2018 Hackaday Superconference talk, but it’s for good reason. Jeremy knows how to do things like build GPS and radar jammers, which are federal crimes. Even he hasn’t put his knowledge to practical use, having built only devices that never actually emitted any RF.

So what does one talk about when circumspection is the order of the day? As it turns out, quite a lot. Jeremy focused on how the …read more
