The article discusses the use of targeted advertising data by government agencies, particularly focusing on how a technology consultant demonstrated the security risks posed by Grindr's data to national security agencies. It highlights the widespread availability and potential surveillance applications of advertising data, as well as the government's interest in obtaining and utilizing such data for intelligence purposes.

Why is this worth the read? It goes into detail how these data exchanges work and the mechanisms of obtaining such data. We often hear about the result of these actions, but how these actions are performed are described within.

Below is a disturbing amount of information data brokers have ammased from buying your data from trackers in ads and apps.

"a staggering amount of sensitive and identifying information about consumers," alleging that Kochava's database includes products seemingly capable of identifying nearly every person in the United States.

... can access this data to trace individuals' movements—including to sensitive locations like hospitals, temporary shelters, and places of worship, with a promised accuracy within "a few meters"—over a day, a week, a month, or a year. Kochava's products can also provide a "360-degree perspective" on individuals, unveiling personally identifying information like their names, home addresses, phone numbers, as well as sensitive information like their race, gender, ethnicity, annual income, political affiliations, or religion, the FTC alleged.

... target customers by categories that are "often based on specific sensitive and personal characteristics or attributes identified from its massive collection of data about individual consumers." These "audience segments" allegedly allow advertisers to conduct invasive targeting by grouping people not just by common data points like age or gender, but by "places they have visited," political associations, or even their current circumstances, like whether they're expectant parents. Or advertisers can allegedly combine data points to target highly specific audience segments like "all the pregnant Muslim women in Kochava’s database," the FTC alleged, or "parents with different ages of children."

For all you USA peeps:

A bipartisan team of U.S. lawmakers has introduced new legislation intended to curb the FBI's sweeping surveillance powers, saying the bill helps close the loopholes that allow officials to seize Americans' data without a warrant.

The bill follows more than a decade of debate over post-Sept. 11, 2001, surveillance powers that allow domestic law enforcement to warrantlessly scan the vast mountains of data gathered by America's foreign surveillance apparatus.

The sudo-rs project improves on the security of the original sudo by:

• Using a memory safe language (Rust), as it's estimated that one out of three security bugs in the original sudo have been memory management issues

• Leaving out less commonly used features so as to reduce attack surface

• Developing an extensive test suite which even managed to find bugs in the original sudo

I have a device that reached end-of-life support and I'm burned out loading ROMs to extend it's support. Upon from my return from the trip I plan on purchasing a new device anyway, so buying one while traveling is also an option.

I'm traveling to a European Market that has stronger privacy rules GDPR and their devices must have lower SAR (regarding phone RF emissions).

Regarding RF and SAR

My carrier frequency bands in my home country are supported by European phones I'm looking at (Android and Apple). But do the phones dynamically manage the RF emission based on locale or are the limited at hardware or software?

Would purchasing the device abroad have an effect I think it does when I bring it home?

Regarding Privacy

This one is tricky, typically the account (gmail or Apple ID) is associated with the locale. If I were to create a new account and set up my device while abroad, will this have lasting effects? I have a friend who have immigrated and set their devices up abroad and their locale is still their OG country. One of them changed locales (for android) because spotify (app) wasnt available in their home country locale. So I speculate this is a solid approach if I were to do so.

I know I might have issues with availability of content (downloading from app stores). But as far as accounts go, my Spotify (and netflix if i stil had it) account is associated with my home country so I will still be able to watch shows in my locale. Being able to download the app is the limiting factor but there are ways to get around that with side loading.

So yeah, if anyone has experience with this and could call out some things I didn't consider or validate my expectations, would be appretiated.

Drawing attention on this instance so Admins are aware and can address the propagating exploit.

EDIT: Found more info about the patch.

A more thorough recap of the issue.

GitHub PR fixing the bug: https://github.com/LemmyNet/lemmy-ui/pull/1897/files

If your instance has custom emojis defined, this is exploitable everywhere Markdown is available. It is NOT restricted to admins, but can be used to steal an admin's JWT, which then lets the attacker get into that admin's account which can then spread the exploit further by putting it somewhere where it's rendered on every single page and then deface the site.

If your instance doesn't have any custom emojis, you are safe, the exploit requires custom emojis to trigger the bad code branch.
