Robbedoeson Show HN: Spip – Open-Source Self-Hosted TCP Network Sensor

Good suggestion. To be honest, Cgo was the easiest for me to implement, as I originally wrote the tool in a different language. Also, most of the documentation for Netfilter and SO_ORIGINAL_DST is in C.

As for results: I’m seeing about one 'hit' per second on a standard VPS. It's a constant stream of bots looking for exploitable systems and probes from scanners like Shodan and Censys. It’s actually surprising how quickly a new IP gets picked up by these crawlers.

It seems this is only the case if it's a tweet that contains a retweet. These are now removed from the stream as they're not of relevance.

Am a fan of your work! Would it be useful if I throw these domains directly to URLScan? For retrieving the results I'll probably have to setup a proper DB and a workflow around parsing the Twitter content. Now, it's just a simple script.

Interesting! Will have a look on what they can freely offer.

Plan in the future is to visit the links, download malware and upload it to VirusTotal, Malwarebazaar, etc.
