if you want to know more than you should about how X screen lockers (don’t) work you can go check jwz’s blog

Lol just submit a pr to add a vulnerability while you're add it.

wow that's hosed up. it'd be one thing if the research was about intentionally getting these requests reverted via PRs, but the paper's just fingerprinting:

quote:

Firefox
As part of our experiments we also test Firefox. Interestingly, while the developer documentation and source code include functionality intended for favicon caching [27] similar to the other browsers, we identify inconsistencies in its actual usage. In fact, while monitoring the browser during the attack’s execution we observe that it has a valid favicon cache which creates appropriate entries for every visited page with the corresponding favicons. However, it never actually uses the cache to fetch the entries. As a result, Firefox actually issues requests to re-fetch favicons that are already present in the cache. We have reported this bug to the Mozilla team, who verified and acknowledged it. At the time of submission, this remains an open issue. Nonetheless, we believe that once this bug is fixed our attack will work in Firefox, unless they also deploy countermeasures to mitigate our attack (we provide more details on our attack’s disclosure in §VII).
let's just gloss over any research on tor's hardening of fingerprinting mechanisms in firefox specifically and why this might be the case...
e:

quote:

Ethics and disclosure
First we note that all of our experiments were conducted using our own devices and no users were actually affected by our experiments. Furthermore, due to the severe privacy implications of our findings we have disclosed our research to all the browser vendors. We submitted detailed reports outlining our techniques, and vendors have confirmed the attack and are currently working on potential mitigations. In fact, among other mitigation efforts, Brave’s team initially proposed an approach of deleting the Favicon-Cache in every typical “Clear History” user action, which matches our “Cookie-tied favicon caching” (see §VI) mitigation strategy that can work for all the browsers. The countermeasure that was eventually deployed adopts this approach while also avoiding the use of favicon cache entries when in incognito mode. Additionally, the Chrome team has verified the vulnerability and is still working on redesigning this feature, as is the case with Safari. On the other hand, the Edge team stated that they consider this to be a non-Microsoft issue as it stems from the underlying Chromium engine.
ahahahaha:

quote:

Nonetheless, browsers like Brave have recently adopted built-in anti-fingerprinting techniques which can affect our attack’s performance (while Tor has done so for years, we do not consider it in our experiments since it is not susceptible to our favicon attack).
did.. did they think tor's anti-fingerprinting wasn't in firefox for the most part?

I guess it does actually show that there's a problem if it's easy for someone to get them to revert changes that were made intentionally to prevent fingerprinting, which is kind of interesting, although that's obviously not what the person was trying to do, as Wiggly Wayne DDS said.

yeah, I would expect some doc or better test around this thing (though the cache semantics were undercovered by automated test last I looked, so it might be a fair bit of work)

I love the security researcher asking for susceptibility to their pet tracking vuln, though. very high energy

Former ADT employee Telesforo Aviles took note when there were attractive women at a home he serviced in the Dallas area. Then he would add his personal email address to their accounts so he could have around-the-clock access to their most private moments, according to the U.S. Attorneys’ Office.
Now Aviles faces up to five years in federal prison for accessing roughly 200 accounts more than 9,600 times without consent, over a four-and-a-half year period.

we all know this won't be the first or last time, but lockscreen bypasses are always fun, especially when they involve bitlocker which is supposed to be microsofts big security framework

it's meant to be a combination of PAM+LUKS/GELI? although to be fair, there's been something like half a dozen screenlocking bypasses on Unix-likes in the past half decade

Don't count on an unhardened consumer OS to have a magical "protect me" button. It's definitely a bypass, but it required the machine to have a user account with automatic recovery options enabled. Without a competent sysadmin and a TPM, all you should really count on bitlocker for is having a thief format the machine instead of snooping.

Yeah, that's fair - but I just enjoy lockscreen bypasses, since it seems inevitable.

One lawsuit was filed on behalf of ADT customers, and the other on behalf of minors and others living inside the homes. The lead plaintiff in one of the lawsuits was a teenage girl during the time that the breach occurred. ADT informed her family that the technician spied on them nearly 100 times, according to the lawsuit.

ADT marketed the camera systems as a way for parents to check in on kids and pets with live streaming video, yet failed to implement standard safeguards like dual authentication or text alerts when parties access the accounts. The breach was discovered when a customer noticed an unauthorized email among addresses that had permission to access the security system.
how dare u log on to the camera i installed in my teenage daughter's bedroom to spy on her!
