- I think what we have to start accepting even security experts is that our world is incredibly fragile. I think people realy understimate this. And I do not mean just the IT world but the entire world is built on many incredibly fragile balances. Security Exploits will always exist. Not just in software but in real life. Heck someone managed to Sneak into a Security Conference. And that guy was a random youtuber. Granted that was not like a high security thing. But thats just an example I had of the top of my head. Basically it is realy easy to circumvent security in most cases.
What I want to say with that is fundamentally our world works because atleast most people do not abuse shit. That is fundamentally how human society has always worked, and will likely continue to do so.
by mastermage - For the newer players who have gotten into continuous integration and containerized builds, consider checking on your systems to be sure you're not pulling 'latest' across a bunch of packages with every build.
We set up our base containers with all the external dependencies already in them and then only update those explicitly when we decide it's time.
This means we might be a bit behind the bleeding edge, but we're also taking on a lot less risk with random supply chain vulns getting instant global distribution.
- Sorry, I don't get it. What's the chain of reasoning that connects "there are a couple of new Linux local privilege escalation exploits" to "don't install any new software"? Is the threat we're supposed to be concerned about here just a package maintainer publishing malware that uses these exploits?
(Naively, not knowing much about apt-get or yum or other OS package managers, I have always assumed that 1. only a handful of trusted people can publish to the default repos for system package managers and 2. that since I have to run `apt-get install` as root anyway, package installers can completely pwn my system if they want to and I am protected purely by trust. Is some of that wrong? If it's right, isn't it nonsensical to be any more worried about installing new packages in light of these vulns?)
by XCabbage - There's already an okay solution to supply-chain attacks against dependency managers like npm, PyPI, and Cargo: set them to only install package versions that are more than a few days old. The recent high-profile attacks were all caught and rolled back within a day, so doing this would have let you safely avoid the attacks. It really should be the default behavior. Let self-selected beta testers and security scanner companies try out the newest versions of packages for a day before you try them. Instructions: https://cooldowns.dev/by AgentME
- Alternatively, switch to an operating system like FreeBSD which doesn't take a YOLO approach to security. Security fixes don't just get tossed into the FreeBSD kernel without coordination; they go through the FreeBSD security team and we have binary updates (via FreeBSD Update, and via pkgbase for 15.0-RELEASE) published within a couple minutes of the patches hitting the src tree. (Roughly speaking, a few seconds for the "I've pushed the patches" message to go out on slack, 10-30 seconds for patches to be uploaded, and up to a minute for mirrors to sync).by cperciva
- This is a baffling take.. These exploits are local privilege escalations for linux systems. They'll allow an attacker with a foothold in a shared environment or with low privilege access to a system to affect the rest of the system. They aren't RCEs and won't let attackers access environments that they couldn't before other than the shared hosting scenarios. That is absolutely not how most supply chain attacks are carried out. Most supply chain attacks are performed via credential theft and social engineering. The more sophisticated ones are APT style attacks like the Solarwinds one (which were carried out by organisations that would already have exploits like these) or more creative stuff like the Shai-Hulud fiasco. All of these options existed before these LPEs. If you're worried about supply chain attacks you've been worried for longer than Mythos has been out. Not updating your software is never good security advice.
- "Wait a week to install software" does not work. Just a few months ago a massive exploit hit the web, which was a timed attack which sat for more than a month before executing. If everyone starts waiting a week, their exploits will wait 2 weeks. Cyber criminals do not need to exploit you immediately, they just need to exploit you. (It also doesn't change a large range of vuln classes like typosquatting)by 0xbadcafebee
- This was always a nightmare waiting to happen. The sheer mass of packages and the consequent vast attack surface for supply chain attacks was always a problem that was eventually going to blow up in everyone's face.
But it was too convenient. Anyone warning about it or trying to limit the damage was shouted down by people who had no experience of any other way of doing things. "import antigravity" is just too easy to do without.
Well, now we're reaching the "find out" part of the process I guess.
