Interesting. I didn’t know that syncthing does hole punching.

From a defense perspective, how would this work with an enterprise firewall, with UDP/TCP only allowed to specific destinations or specific sources. Example: only the internal DNS relay server can access 53/UDP and only the internal proxy server can access 80/443. What I mean is in a network with a very closed firewall, how would Syncthing be able to connect with peers?

Instance Rules

Be respectful. Everyone should feel welcome here.

Not necessarily. Torrent is a way to find a peer for direct connection or via a relay (of course that is more than that). Syncthing, even using a relay server, requires some ports available for at least outbound connection (22000 TCP/UDP or whatever port the relay is using). This should not be possible in a medium security network, let alone a defense network. I don’t know if syncthing works without a direct connection (to the peer or relay, something like transport via http proxy).

Honestly, I didn’t think about vulnerability in SyncThing when I read the article. But I wondered why defense forces would have p2p open on their networks.

By the messages that they are sending to customers, looks like is related to recent updates to the services, but nothing clear.

IoCs available in the original article.

Please note that the attack can only be carried out if the local network itself is compromised.

IoCs available here. Some of them with no detection on VT.

MS involved. Again.

Of course, in the end it is just conflict, and when it spills over into the real world then you have a war. But this is not always the case We have already had disruption in power grids, nuclear plants, hospitals, public offices, critical infrastructure of financial markets (some of them with impact in real lives) without retaliation in the physical world.

Cyberwar, in my perspective, have some nuances. For instance, in a physical conflict, a hostile nation’s invasion of my property immediately becomes a state issue. However, this isn’t always the case in a cyberwar if a hostile state invades my organization (It’s hard to immediately distinguish whether the actor is a nation state, a financially motivated group, hacktivists, or just a guy who eats pizza in his mom’s basement). Most of the time, organizations are on their own.

In a cyberwar, espionage is also far more acceptable. This is something the NSA (and FSB/SVR) has been doing for years (against private entities and states). In a way, I understand that it is something similar to what the cold war was (is), but with no boots on the ground.

I’d better say that states have been doing this.

Cyber war, of course. I think that there is a cyber war going on for quite some time now. CWWI (Cyber World War I).

If anyone is still using it, anyways…

Maybe cyber resilience? Quick identify, respond and recover from an incident.

Hackers 10 - 1 LastPass

From the article:

Microsoft locked down a server last month that exposed Microsoft employee passwords, keys and credentials to the open Internet, as the company faces growing pressure to strengthen the security of its software. Microsoft was notified of the vulnerability on February 6th and the block on March 5th. It is unclear whether anyone accessed the exposed server during this period.

Good bot

In this particular case, the method of infection of the router was not disclosed. However, typically, the most common methods involve an open administration port to the internet (user interface or TR-069) or through the internal interface, in case a network host has been compromised.

They often perform brute-force password attacks, and once access is obtained, they look for typical Linux administrative tools (such as bash, etc.) and proceed to compromise the router.

So I understand that a router with custom firmware can be compromised if it has a weak password and resources to maintain the infection, or of course, a vulnerability that is exploitable.

Not following… Since this is a cybersecurity com, I assume that many of us work in this area, literally defending people and organizations from attackers and scammers. That’s why I said some of us make a living out of this in a sad way.
