A look back, a look ahead: How was 2024 at IzzyOnDroid? What might 2025 bring you there, what are we working on?

And if anybody ever tells you #security or #reproducibleBuilds are "set-and-forget", laugh straight into their faces. Software evolves, and so do their threats and risks…

At last, the USB portal originally authored by @refi64 in 2021, later continued by Georges Stavracas in 2023, and finalized by @hub, has been merged!

The USB portal allows sandboxed formats like Flatpak to access USB devices without poking holes in the sandbox. This is great for security, as accessing USB devices will now need to be explicitly granted by the user.

Now we just need to wait for implementers to implement them in their respective portal implementations, starting with GNOME: gitlab.gnome.org/GNOME/xdg-des…

The documentation for the USB portal is available on the xdg-desktop-portal website: flatpak.github.io/xdg-desktop-…

Repeat offenders drive bulk of tech support scams via #Google #Ads

"Search engines, and Google’s in particular, are our gateway to the web. Yet, that door sometimes opens up to unsavory places thanks to sponsored search results, AKA ads."

This is part of the reason I recommend using an #adblocker (whether in browser, on device, or network-based.)

I've noticed a concerning trend of "slop security reports" being sent to open source projects. Here are thoughts about what platforms, reporters, and maintainers can do to push back:

Synapse 1.120.2 was just released with several security fixes: github.com/element-hq/synapse/…
You should really update now and while the last 2 CVEs say, they were fixed on 1.106, to my knowledge that is only true if you enabled authenticated media, which only became the default in 1.120, so you really want to update even for those or at least update your config.

Thank you! :)

Gmail and Outlook are popular but not necessarily the best - especially when it comes to #privacy and #security.

In this in-depth guide we review #Gmail vs #Outlook and fill you in on the best email provider that's ad-free, private, and secure. 😉

This article discusses how to protect privacy, amidst concerns of increased government surveillance.

The article is aimed at Asylum seekers & immigrants to the US, but it's solid advice for anyone, really.

Recommendations include using encrypted messaging apps like Signal, Apple iMessage, and WhatsApp, and setting messages to disappear.

It also recommends minimizing data sharing and deleting data when possible, particularly from Google.

Oha, das ist provokativ: Dieser Blogartikel sagt:

- Nutzt kein #PGP / #GPG
- Nutzt kein #XMPP + OMEMO
- Nutzt kein #Matrix (im Sinne: verlasst euch nicht auf die Verschlüsselung)
- E-Mails verschlüsseln ist sinnlos

Ich kenne den Autor nicht und würde ihn nicht erwähnen, würde der Artikel nicht in ernstzunehmenden ITSec-Newslettern zitiert

Meinungen? #itsec #security


I've seen a number of toots today advising people against scanning random #QRCodes because they can be used in a number of malicious ways.

There are a number of legitimate ways people can use such codes to trick others, and it can require some deeper understanding of how systems work to avoid them. For that reason, I'm not going to contradict that recommendation, but I will add to it.

QR codes are usually just URLs encoded in a visual, machine-readable form, so they aren't necessarily more dangerous than a link. The danger comes from the fact that most scanner apps will directly open whatever URL you scan without giving you the opportunity to consider whether that's a good idea.

You can reduce the risk of scanning such codes by installing a better app which requires manual interaction to open URLs after decoding them.

For android users I recommend "BinaryEye", since it's open-source, ad-free, and has a bunch of other useful features.

Its github page links to both F-Droid and the play store:

Great to see you're adopting some of the #security features we've implemented earlier this year at #IzzyOnDroid @fdroidorg! Maybe you want to check our documentation on them?

android.izzysoft.de/articles/n…

* it's SIGNING blocks, not FROSTING blocks
* MEITUAN is about payload, not metadata
* there's no fixed number of blocks as your code assumes (gitlab.com/fdroid/fdroidserver…)

The article you link to (bi-zone.medium.com/easter-egg-…) tells you the same :wink:




@Tutanota I just realised that all the comments I have added to my contacts over the years, including family-related and medical important information, are gone...

Bugs are becoming more common recently, and this one made me lose data. I'm quite disappointed.

American Water shuts down online services after #cyberattack

American Water is the largest water and wastewater treatment utility in the US…

OT systems not affected - so appears this only affects their IT systems. Suspected nation state activity (Russia).

(I encourage everyone sharing this with their friends because cyber attacks absolutely can have direct “real world” consequences.)

#AIagent promotes itself to #sysadmin , trashes #boot sequence

Fun experiment, but yeah, don't pipe an #LLM raw into /bin/bash

Buck #Shlegeris, CEO at #RedwoodResearch, a nonprofit that explores the risks posed by #AI , recently learned an amusing but hard lesson in automation when he asked his LLM-powered agent to open a secure connection from his laptop to his desktop machine.

New blog post: Post-OCSP certificate revocation in the Web PKI.

With OCSP in all forms going away, I decided to look at the history and possible futures of certificate revocation in the Web PKI. I also threw in some of my own proposals to work alongside existing ones.

I think this is the most comprehensive current look at certificate revocation right now.

Tor insists its #network is safe after German cops convict CSAM dark-web admin

Kind of boils down to opsec fail here. Using outdated software, which in this case didn’t properly secure Tor connections.

Timing attacks are still viable (especially with hostile nodes), but this reads as an #opsec fail to me.

Remember: a major part of anonymity is maintaining great opsec.

Obligatory: Tor is not “just for criminals,” despite one getting caught in this case (glad he did tbh). Regular people use Tor everyday.

In opsec, duress (“rubber-hose”) attacks are famously hard to address. Cryptographic keys that cannot be lost have poor protections against duress.

Travelers can leave key fobs at home should they be accosted. A victim of a break-in can conveniently “lose” or smash a hardware key, erasing any encrypted data. Yes, I know about cold-boot attacks; I don’t recommend at-risk people to leave things decrypted for long durations. I like the idea of spring-loaded key fobs that can’t be left plugged in.

People talking about key fob body implants don’t usually plan for removing them in seconds with plausible deniability.

Готовые средства обхода. Waujito написал своё решение под линукс (github.com/Waujito/youtubeUnbl…), которое направлено только на ютуб.
Также для Windows существует GoodbyeDPI от ValdikSS (github.com/ValdikSS/GoodbyeDPI), под линукс еще есть zapret (github.com/bol-van/zapret).
Существует ByeDPI (github.com/hufrea/byedpi), который работает как прокси (Windows/Linux). Также есть версия ByeDPI под андроид (github.com/dovecoteescapee/Bye…), работает как "фейковый впн".

Советую прочитать подробный комментарий от ValdikSS о том, как использовать эти средства. (github.com/yt-dlp/yt-dlp/issue…)
