I guess this also rests on my belief that only the DSDT will be re-read from flash on e.g. hotplug events, but if other tables like the XSDT/RSDT are also re-read, I imagine bad things might happen. Anyway, I decided to ask it as an actual question:

Q: Can maliciously modified ACPI AML be executed without a reboot?

forestACPI tables contain ACPI Machine Language, or AML, which is executed by an interpreter in the kernel at boot. Certain ACPI tables, such as the DSDT, are necessary to support hardware ACPI events such as resuming a suspended system. To access these tables, which are stored on the BIOS flash, the k...

Totally random: This was censored by Intel some months ago. I hate how they just ask for anything analyzing their stuff to remove writeups of the analysis.

new open source UEFI BIOS by Microsoft
looks interesting
"This is the same code used today on many of Microsoft's 1st party devices and it will be kept current because it must be to continue to enable shipping products. "

Hi folks. I don't know if it's off-topic so I ask it here first, and will create a question on main website if it's good enough, but here it is : I discover in a small website an sql dump, accessible by anyone (there is no link from the main website to the sql dump file, but you don't need any administrator right to acces the sql dump file)
the website itself is not use anymore, but it still have data about hundreds of customers, including (non-hashed) passwords
 
I smell a legal question here ?
 
It's a small association of local farmers who sell their products directly to costumers, and I don't want to warn them
well, basically it's "What can I do"
 
Oh. -5pts for M'vy.
 
I already send them an email telling that I saw their sql file, and that Im ready to help them if they want
but if I don't have answer, what is the next step ?
 
What's the goal. Remove the dump or warn about password being compromised ?
 
8:21 AM
well, both
I'm probably the first to see the dump, and you reaaly need to want it to find it, but still, it's accessible
the best scenario would be to remove the dump as soon as possible, and then to hash all the passwords
ideally, they should also warn their customer that their passwords weren't protected
 
Well, this would probably fall into the 'responsible disclosure' category. Which is a grey area in many countries
 
well, as I have the email adres of all customers, I could send an email to everyone
 
8:39 AM
can you overwrite data in the dump @Kepotx?
 
no, it's just e text file
I don't try sql injection though
no, sql injection don't seem to work (at least simple one)
 
you can inform law enforcement anonymously
 
sure, but wouldn't that harm the association?
 
8:57 AM
what harms the association is a freely accesible sql dump with user data
there are other people here who have more experience with responsible disclosure
if you have tried to contact them several times and they did not react then it is time to use other means
because their users also have a right to be protected and right now, they are not

The French government has an official page about responsive disclosure
 
thanks
 
I never tried it, so I'm not sure if you'll ever get a reply
 
@TomK. I just send an email monday to a farmer, I don't even know if they handle the website themselves. I will wait a little more and try to warn other people before warning all the users
 
Have you checked the WHOIS to know who handle the website?
 
9:58 AM
a site's certificate can also have some information like an admin's email adress

@Kepotx Don't send a mail to all the users in the dump, that's only asking for trouble.
That's an article by one of the leading security experts on how he handles responsible disclosure
TL;DR: contact the company, if that fails contact the press

Hello all. Suppose you encounter a reflected XSS vulnerability on a State of Florida website. You email details of it to webmaster@somedepartmentorwhatever.org and the email bounces. You then tweet to the department asking who to disclose the vulnerability to and receive no response. What would you do?

- Keep digging for a technical contact?
- Tweet the vulnerable URL with an example payload?
- Forget about it and move on?
- Open a support ticket with a department employee, send them the URL with a cookie-stealing payload, use their cookies to gain privileged access to the site, and deface
 
@jdgregson We have quite a few high-voted questions tagged that should apply here

@Arminius Thanks, I'm reading through some. Consensus seems to be "if they don't have a policy in place then they don't care about their security and neither should you." Fair point. I don't even live in Florida.
