Monitored SIEM: We're seeing some unusual port scanning activity

Sys Admin: It's me, hi, I'm the problem, it's me

#sysadmin #security #networksecurity #nmap #portscan #firewall

Are there lots of port scan bots on the loose again today? I got over 700 new IP bans in the Fail2Ban recidive jail today. Lot's of IP's from the communistic orc Federation and from China, too. Annoying...

TIL The FreeBSD kernel auto-tarpits (for want of a better word) portscans on your host as soon as they attempt to connect to a closed port. If you see the following in your logs, that’s what’s happening.

"kernel: Limiting closed port RST response from 3877 to 190 packets/sec”

Shodan - looking at you!

You can have more fun using blackhole in sysctl

https://man.freebsd.org/cgi/man.cgi?query=blackhole&sektion=4&manpath=freebsd-release-ports

None of this is a substitute for a firewall.

someone's bot net is giving it a go #sysadmin #crowdsec #botnet #portscan

For anyone interested: I'm now using Port Authority. It's free, open source and works nicely.

“Brave aims to curb practice of websites that #PortScan visitors. Brave will allow users to choose which sites can access [#localhost] network resources.” Dan Goodin, Ars Technica #Privacy #WebBrowsers

This should be the new #WebPlatform standard: deny by default. A handful of allow-by-default exceptions for PC vendors’ support sites that connect to a helper service on a specific port to identify the model and installed driver versions. One of very few legitimate uses.

anybody here use #masscan on internal pen tests if the network is big? I'm looking for advice on what rate you might run at. I'm not worried about noise, I am worried about swamping the network.

Yesterday a ~6000 members #botnet started to #portscan hosts en masse. Watch out.
