All this spectre/meltdown stuff, what's the actual risk to the kind of end-user who only uses their unpatched device for loving around on social media? A malicious JS somehow runs for days and eventually pulls a cached password out of memory?

If your browser doesn't have the right mitigations, it might be more like minutes. And we have to hope they didn't miss any subtle ways for JS to accurately measure time.

But yes passwords, or any files you've opened recently.

Not many other paths to get in.

I know the answer is wipe and reinstall if you think there might be a virus, but if I can’t convince someone to do that, what’s the next best thing? I’m taking a look at my neighbor’s dad’s computer in exchange for a tow my neighbor gave me. He thinks there’s a virus.

He might have adware or just a PC full of random poo poo but the probability of a random user being able to actually detect a virus on their PC is near nonexistent. Why does he think he have a virus? There is probably something else wrong and you should focus on determining why he is concerned and tracking down whatever its root cause is, instead of focusing too much on his speculation of evil hacker viruses.

Yeah, I'm really hoping it's not a virus. The thing is that it's my neighbor's dad's, and his dad is halfway across the country (at a cancer treatment center), so all I've got to go on is second hand. It probably is just slow and full of bloat and ads. Is there anything else I should be running to search for poo poo, though?

If I find Bonzi Buddy somehow I'll make sure to let you all know.

My general tidy-up flow for relatives etc is very simple. If there is something undesirable-but-not-outright-virus running on the PC, the crucial bit is that it has to run to do anything. This means that it either exists as its own process or as a plugin in some other process.

So I just go through all browser plugins, removing any that seem suspect, and then go through all running and autostarting processes, removing any that are suspect from disk and autostart. That's it - last time I encountered something that needed anything more in depth than this on a personal device was over 15 years ago.

Sysinternals procexp and autoruns are good tools for this. It does rather require you to have a good feel for what is expected and what is not, though.

ComboFix was always my go-to for bringing a malware'd box back to sanity when they REALLY didn't want to wipe and reinstall. Looks like it still exists and is still being updated, although I haven't used it in years and can't speak to how well it currently works.

I taught my mom to learn how to use noscript and i love she was able to reconize how much bullshit it blocks when you start blocking everything not five of her main websites she visits.


She even brags about it to while my uncles, aunt's, and cousin computers are constantly being infected by malware.

Is the Sophos bootable thing still the best way to go? And since it boots it’s own OS, there’s no risk of bringing something back on the USB drive when it goes into another computer, right?

Does Malwarebyes suck now or always? We always used it at two jobs I had. What I found out shortly before leaving the last one was that we used it illegally because we used the free download version which has a line in the EULA forbidding business use.

It, like all anti viruses, can only detect a small number of attacks and cannot guarantee that you got everything. In exchange for this questionable value you increase the size of your computer’s attack surface.

Though, probably useful is the wrong word.

What I really mean, is how likely it is that someone is going to use Strava to do something bad rather than getting their own data.

In other words, will there be an attack on a base because of this data that wouldn't happen otherwise.

I'm not convinced.

In my experience gyms and pt routes are clearly marked on post.

Also, if you are not a felon, get a job as a pizza delivery driver in the town closest to the base in question and you will get more and more useful information than I’ve seen on these strava screenshots.

I don't see how identifying even the tiniest military outpost's exact location, possibly several of their inhabitants real identities, and their actual real life physical movements could ever be meaningfully used against them by someone with bad intentions when all you have to do is get a pizza route in Mosul.
