The London Underground is actually kind of a dumb use-case because it’s fixed infrastructure.

On the other hand it’s a perfect test bed, because there’s sufficient changes of direction and speed, and the fixed infrastructure lets you measure drift. Plus it being underground helps simulate GPS signal being weak or unavailable.

When I was younger and more naïve, I used to think a case was useless. I kept my phones in my pocket most of the time, and didn’t feel particularly clumsy or reckless. Then I got a phone that happened to have a glass back, and it broke not because I fumbled it, but because it slid out of my pocket onto time floor while I was sitting down. Glass backs on phones are bullshit.

I found the netrunner jobs more entertaining and rewarding. Gangs are tough initially, once you get better weapons you go through them like a hot knife through butter.

As in you are seeing multiple boot entries? It’s likely one entry per kernel version that you have installed. It doesn’t happen often these days any more, but in some situations it’s handy to be able to revert to a previous kernel if for example third party modules break.

It has implications on the effectiveness of VPNs on public networks.

lemmyng , 1 month ago

Sure they can. If you put a network behind a router they will share an egress/ingress IP. And there are certain high availability setups where computers share IPs in the same subnet for hot/standby failover.

Phone numbers can be spoofed, and SIM cards can be cloned. The analogy stands.

When you do call routing with a PBX each phone has an unique extension, equivalent to the private IP of each host.

Oh, and there’s also anycast, which is literally multiple active devices sharing an IP.

A phone number does not uniquely identify a phone either.

Laptops don’t get a new IP address every time they switch from one AP to another in the same network either. Your cell phone will get a new IP address if it switches to a different cell network.

Whoa, that’s a sizeable edit to the post! Regardless the answer is pretty straightforward: your VOIP client (either the device if you have one or the software) is connected to a VOIP service which acts like a gateway for your client. Since the client initiated the connection to the gateway and is keeping it alive, you don’t need to make any network changes. Once the connection is established, standard SIP call flows (you can Google that for flow diagrams) are followed.

So no, you router is not part of the cell service. The VOIP provider is part of a phone service that receives calls and routes them for you, just like the cell towers are part of a telephony provider that routes calls through the appropriate tower.

1. A static IP is actually not necessary, but what you need is a consistent identifier. For the server, that’s typically a DNS address, but for clients and peer to peer networks there’s other ways to identify devices, usually tied to an account or some other key kept on the device.
2. For centralised communications yes, you would need an always online server. For decentralised networks, you just need a sufficient amount of online peers, but each individual peer does not need to be always online.
3. Pretty much, yes. Even push notifications on cell phones work this way.
4. Route, yes. Manually. VPN is usually not necessary. In modern web-based services this is typically done with websockets, which are client-initiated (so the client address can change), and which allow two-way communication and typically only require a keepalive packet from the client every minute or so.

There’s other reasons why universal addressing is not done - privacy, network segmentation, resiliency, security, etc. And while IPv6 proponents do like to claim that local networks wouldn’t be strictly necessary (which is technically true), local networks will still be wanted by many. Tying this back to phone numbers - phone numbers work because there’s an implicit trust in the telcos, and conversely there’s built in central control. It also helps that it’s only a very domain specific implementation - phone communication specifications don’t change very often. On computer networks, a lot of work has been done to reduce the reliance on a central trust authority. Nowadays, DNS and SSL registries are pretty much the last bastion of such an authority, with a lot of research and work having gone into being able to safely communicate through untrusted layers: GPG, TOR, IPFS, TLS, etc.

Not sure what you are talking about. Paragraph 1 has

The malware is delivered through a fake Google Chrome update that is shown while using the web browser.

and the article makes it pretty clear after that that the user is tricked into installing the fake apk.

I used to be a teaching assistant at university, and never sorted by name. But based on my experience I don’t think it’s frustration that accounts for the disparity, it’s that as you see more and more assignments you start getting a feel for common issues and are able to point them out more easily. I would always do two passes because of that to ensure that I normalized the weight of my marking.

Just because it has a CVE number doesn’t mean it’s exploitable. Of the 800 CVEs, which ones are in the KEV catalogue? What are the attack vectors? What mitigations are available?

lemmyng , 2 months ago

The fact that you think it’s not possible means that you’re not familiar with CVSS scores, which every CVE includes and which are widely used in regulated fields.

And if you think that always updating to the latest version keeps you safe then you’ve forgotten about the recent xz backdoor.

lemmyng , 2 months ago

I don’t know where you got the idea that I’m arguing that old versions don’t get new vulnerabilities. I’m saying that just because a CVE exists it does not necessarily make a system immediately vulnerable, because many CVEs rely on theoretical scenarios or specific attack vectors that are not exploitable in a hardened system or that have limited impact.
