Durov gets arrested in france and suddenly the telegram slander kicks into high gear. It gets a hit piece every once in a while for sure, but the last few days have been on a different level.
You know who else uses telegram? My family, to send vacation pics to each other.
You know what other technology bad guys use? Email.
Private trackers disgust me. What kind of pirate turns away from the world, to re-seeding fragments of files they don’t care about to other cowards with slightly slower rss feeds; all for a chance at enough ratio to get the show you want? It’s a country club, with self-validating assholes, dry hot dogs, and tall fences.
The Mainline DHT is the way forward. There is no social credit here. The kids in Africa are starving, and I will throw them as much as I can, kilobyte by kilobyte, for no reason at all, for I too was a leecher once.
2014 impreza. No screen at all. I bought a phone mount that shows waze and charges my phone.
I have cruise control and heated seats. And I can operate both with gloves on!
Don’t need a backup cam because my windows and mirrors are good.
I will drive this car until it dies, and then I’ll replace the head gaskets and drive it until it dies again. And then I will replace the cvt and drive it until it dies a third time.
Unfortunately there’s nothing you can do about the NY road salt. The frame will be left, flake by flake, in the gutters of 490. It’s the only thing that can take this car from me, and it is its inevitable fate.
Did you know that in the first version of php, each function name would be hashed to lookup the code to run it? And the hashing algorithm was: the first letter. So all the functions started with a different letter.
Anything exposed to the internet will be found by the scanners. Moving ssh off of port 22 doesn’t do anything except make it less convenient for you to use. The scanners will find it, and when they do, they will try to log in.
(It’s actually pretty easy to write a little script to listen on port 20 (telnet) and collect the default login creds that the worms so kindly share)
The thing that protects you is strong authentication. Turn off password auth entirely, and generate a long keypair. Disable root login entirely.
Most self-hosted software is built by hobbyists with some goal, and rock solid authentication is generally not that goal. You should, if you can, put most things behind some reverse-proxy with a strong auth layer, like Teleport.
You will get lots of advice to hide things behind a vpn. A vpn provides centralized strong authentication. It’s a good idea, but decreases accessibility (which is part of security) - so there’s a value judgement here between the strength of a vpn and your accessibility goals.
Some of my services (ssh, wg, nginx) are open to the internet. Some are behind a reverse proxy. Some require a vpn connection, even within my own house. It depends on who it’s for - just me, technical friends, the world, or my technically-challenged parents trying to type something with a roku remote.
After strong auth, you want to think about software vulnerabilities - and you don’t have to think much, because there’s only one answer: keep your stuff up to date.
All of the above covers the P in PICERL (pick-uh-rel) for Prepare. I stands for Identify, and this is tricky. In an ideal world, you get a real-time notification (on your phone if possible) when any of these things happen:
That list could be much longer, but that’s a good start.
After Identification, there’s Contain + Eradicate. In a homelab context, that’s probably a fresh re-install of the OS. Attacker persistence mechanisms are insane - once they’re in, they’re in. Reformat the disk.
R is for recover or remediate depending on who you ask. If you reformatted your disks, it stands for “rebuild”. Combine this with L (lessons learned) to rebuild differently than before.
To close out this essay though, I want to reiterate Strong Auth. If you’ve got strong auth and keep things up to date, a breach should never happen. A lot of people work very hard every day to keep the strong auth strong ;)
For the Nth time, crowdstrike circumvented the testing process
Edit: this is not to say that cs didn’t have to in order to provide their services, nor is this to say that ms didn’t know about the circumvention and/or delegate testing of config files to CS. I’ll take any opportunity to rag on MS, but in this case it is entirely on CS.
Crowdstrike is big, but not that big.
About half of my clients use them; and of those, about a third are halfway through ripping them out in favor of MS defender.
(MS is definitely “that big”)
I want to spin up a separate thread here if that’s okay.
Please give me an example of any EDR solution produced through “public ownership structures”. I don’t think such a thing exists, but I welcome being proven wrong.
Private ownership and investment of capital created Crowdstrike as a profit-seeking venture. It also created MS Defender, SentinelOne, trellix, carbon black, etc. Competition in the marketplace (and there was/is lots of competition) forced these products to be as good as they could, and or self-stratify into pricing tiers. Crowdstrike, being the best (and most expensive) is the most widely-used. Note that not every enterprise requires that level of security, and so while CS is widely used, it is not ubiquitous. This outage could have been significantly worse.
Crowdstrike runs at ring 0, effectively as part of the kernel. Like a device driver. There are no safeguards at that level. Extreme testing and diligence is required, because these are the consequences for getting it wrong. This is entirely on crowdstrike.
Wiz scans clouds for “vulnerabilities”, and sometimes provides remediation advice. For example, if a vm’s kernel is outdated, it might recommend “sudo dnf remove —purge kernel”. And yeah, there sure won’t be any vulnerabilities after that.
It also complains about anything internet facing - including intentionally internet facing services - but that’s another rant for another time.
It’s not rocket appliances
The Taos might be the play - I am very nearly in love with the Golf, and even though I love a small car, it’s just slightly too small. I want to fit at least a hiking backpack in the trunk.
I have no context for how expensive a bmw is. I assume it’s more than 20k? - how much more? 50k?
I’m trying to save for a house downpayment but have also been thinking about a new car, and the Tiguan looks kinda nice, assuming it’s not one of those touch screen cars
Edit: I am a fool, the tiguan is a VW.
But MS teams is very secure! It’s sandboxed in a web browser :) It’s effectively a single-tab display of an entire ram-eating chromium process :)
The only unfortunate side effect is that it can’t read your system default audio output, so it uses a cryptographically secure random number to decide which other audio output to use. That’s right - it very securely knows about all of your audio outputs, even though they aren’t the system default :)
Did you just try to send someone a file? Don’t worry, I’ve put the file in sharepoint for you, and have sent them a link instead. Actually, wait - you had already sent that to someone else, so I sent file (1).docx instead. Actually wait - that was taken too. Now it’s file (2).docx.
I would like to provide a friendly reminder that you will need to manage the file sharing permissions in sharepoint should anyone else join this 1-on-1 direct message chat :)
I strongly recommend the NAT loopback route over attempting split-horizon dns.
I think it’s a D-tier article. I wouldn’t be surprised if it was half gpt. It could have been summarized in a single paragraph, but was clearly being drawn out to make screen real-estate for the ads.
Get yourself a $5 vpn service and read up on the “Mainline DHT” :)
I’m happy to revisit and explain, but I don’t have much time to type right now - the wikipedia page for estonia has great info; you will need a basic understanding of cryptographic hashing and merkle trees
I love Ed. He is a fantastic writer.
