Please boost for visibility! If you are running a #Mikrotik router or switch, upgrade it now. Right now. The fixed releases are 7.23.4 (long-term), 7.24.2 (stable) and 6.49.21. If you are running a version less than that, there are multiple entrypoints for a complete unauthenticated remote code authentication. This is as bad as it gets, upgrade and reboot now. Yes, you'll have an outage for a few minutes, but it's better than the alternative. #router #ipv4 #ipv6

ARP is one of those protocols everyone can define, but far fewer can explain in detail. I put together a comprehensive guide covering protocol internals, operating system behavior, Wireshark analysis, security implications, and modern enterprise defenses. Feedback is welcome. https://thecybersecguru.com/networking/address-resolution-protocol-arp/ #Networking #CyberSecurity #IPv4 #Wireshark

Has anyone got a tip for a #nixos version of #tpotce https://github.com/telekom-security/tpotce or similar #tarpit like #honeypot #ids #ips ? How does one easily obtain a suitable #ipv4 & #ipv6 address if one rightly does not want to use one's own?

A Farewell to ARPs: IPv4 Service on IPv6-Only Networks

IPv6-only networks often still depend on IPv4 subnets and ARP. This article introduces an IETF proposal to eliminate both, allowing IPv4 to operate as a service over IPv6-only infrastructure without translation or tunnelling.

I’m tinkering with a free #BGP peering service (by own VMs) for hobbyist AS owners, including free upstream connectivity at various locations. It’s still in the early stages, but I’d love to hear what features the community would find most useful. Wondering how and why? With @BoxyBSD@mastodon.bsd.cafe and @BoxedTux@mastodon.social, I’m already running platforms that provide free VPS instances for educational purposes, learning and testing for years now. I guess, providing real AS and peering services (maybe even sponsoring LIR in cooperation [but this would cost money]) could also be very interesting for several ones, apart from the DN42 network. Happily looking for feedback… #isp #network #networking #ipv6 #as #autonomoussystem #ipv4 #free #opensource #devops

Replying to
@Arusekk@infosec.exchange I'll be able to go #IPv6 once it's mandatory. Sadly it ain't but in fact many applications mandate #IPv4 to this day…I unsarcastically want #IPv8 (minus the obvious bullshit!) The only reason IPv6 traffic is increasing is propably becaise #MNO|s and #MVNOs still do #CGNAT on #RFC1918 address spaces, thus bricking #VPN|s. This was literally the reason I had to setup #DualStack at some company!
