im aiming to make a chat app secure as theorhetically possible as a webapp. for transparency its open source. id like the experience to be as close to possible to a regular chat app. its important to note; there are limitation with p2p and webapps such that messages cant be sent if the peer isnt connected.

to keep this post brief, please take a look at the readme. it has all the information and links.

i dont think its ready to replace any app or service, but id love to get feedback on what you think would make it so you would use it more than once.

Funding

The NGSOTI project is dedicated to training the next generation of Security Operation Center (SOC) operators, focusing on the human aspect of cybersecurity. It underscores the significance of providing SOC operators with the necessary skills and open-source tools to address challenges such as detection engineering, incident response, and threat intelligence analysis. Involving key partners such as CIRCL, Restena, Tenzir, and the University of Luxembourg, the project aims to establish a real operational infrastructure for practical training. This initiative integrates academic curricula with industry insights, offering hands-on experience in cyber ranges.

vulnerability-lookup is co-funded by CIRCL and by the European Union. Views and opinions expressed are however those of the author(s) only and do not necessarily reflect those of the European Union or ECCC. Neither the European Union nor the granting authority can be held responsible for them.

Media coverage largely sucked

When I just looked at my phone, the headlines were about an unfolding Microsoft global IT outage. My first thought, ransomware. So I logged in and started looking around at what was happening — I’m a CrowdStrike customer — and quickly realised two different, separate things had happened:

• Microsoft Azure had an outage earlier in the day. This was resolved before I got up. Azure has frequent outages (don’t kill me, Microsoft) — this isn’t abnormal.
• CrowdStrike had made a boo-boo and pushed out a channel update that had borked a decent percentage of customers.

The media connected these two events together and conflated them. They weren’t connected.

We're happy to announce that BusKill is presenting at DEF CON 32.

BusKill is presenting at DEF CON 32

via @[email protected]

What is BusKill?

BusKill is a laptop kill-cord. It's a USB cable with a magnetic breakaway that you attach to your body and connect to your computer.

Watch the BusKill Explainer Video for more info youtube.com/v/qPwyoD_cQR4

If the connection between you to your computer is severed, then your device will lock, shutdown, or shred its encryption keys -- thus keeping your encrypted data safe from thieves that steal your device.

What is DEF CON?

DEF CON is a yearly hacker conference in Las Vegas, USA.

What is BusKill presenting at DEF CON?

I (goldfishlaser) will be presenting Open Hardware Design for BusKill Cord in a Demo Lab at DEF CON 32.

What: Open Hardware Design for BusKill Cord
When: Sat Aug 10 12PM – 1:45PM
Where: W303 – Third Floor – LVCC West Hall

Who: Melanie Allen (goldfishlaser) More info

Talk Description

BusKill is a Dead Man Switch triggered when a magnetic breakaway is tripped, severing a USB connection. I’ve written OpenSCAD code that creates a 3D printable file for plastic parts needed to create the magnetic breakaway. Should anyone need to adjust this design for variations of components, the code is parameterized allowing for easy customization. To assemble a BusKill Dead Man Switch cord you will need:

1. a usb-a extension cord,
2. a usb hard drive capable of being attached to a carabiner,
3. a carabiner,
4. the plastic pieces in this file,
5. a usb female port,
6. a usb male,
7. 4 magnets,
8. 4 pogo pins,
9. 4 pogo receptors,
10. wire,
11. 8 screws,
12. and BusKill software.

Golden DIY BusKill Print

Full BOM, glossary, and assembly instructions are included in the github repository. The room holds approx. 70 attendees seated. I’ll be delivering 3 x 30 min presentations – with some tailoring to what sort of audience I get each time.

Meet Me @ DEF CON

If you'd like to find me and chat, I'm also planning to attend:

• ATL Meetup (DCG Atlanta Friday: 16:00 – 19:00 | 236),
• Hacker Kareoke (Friday and Sat 20:00-21:00 | 222),
• Goth Night (Friday: 21:00 – 02:00 | 322-324),
• QueerCon Mixer (Saturday: 16:00-18:00 | Chillout 2),
• EFF Trivia (Saturday: 17:30-21:30 | 307-308), and
• Jack Rysider’s Masquerade (Saturday: 21:00 – 01:00 | 325-327)

I hope to print many fun trinkets for my new friends, including some BusKill keychains.

Come to my presentation @ DEF CON for some free BusKill swag

By attending DEF CON, I hope to make connections and find collaborators. I hope during the demo labs to find people who will bring fresh ideas to the project to make it more effective.

Vulnerability Lookup facilitates quick correlation of vulnerabilities from various sources (NIST, GitHub, CSAF-Siemens, CSAF-CISCO, CSAF-CERT-Bund, PySec, VARIoT, etc.), independent of vulnerability IDs, and streamlines the management of Coordinated Vulnerability Disclosure (CVD). Vulnerability Lookup is also a collaborative platform where users can comment on security advisories and create bundles.

A Vulnerability Lookup instance operated by CIRCL is available at https://vulnerability.circl.lu.

Contrary to what is stated on the polyfill.io website, Cloudflare has never recommended the polyfill.io service or authorized their use of Cloudflare’s name on their website. We have asked them to remove the false statement, and they have, so far, ignored our requests. This is yet another warning sign that they cannot be trusted.

Wall Street Journal (paywalled) The digital payments company plans to build an ad sales business around the reams of data it generates from tracking the purchases as well as the broader spending behaviors of millions of consumers who use its services, which include the more socially-enabled Venmo app.

PayPal has hired Mark Grether, who formerly led Uber’s advertising business, to lead the effort as senior vice president and general manager of its newly-created PayPal Ads division.

Not sure if there’s a better community to ask this, but I’m trying to find a good quality non-cloud-based IP camera that I can feed into a standardized video recording software over a network. Ideally, it would be Wi-Fi capable as well.

Everywhere I’ve looked, they all reach out to a third-party and go through an app or are through junction box and are analog-based.

Does anyone know if an option like this exists?

Und mal wieder: Es ist nur ein Werkzeug, mit dem halt mit genug krimineller Energie auch Blödsinn gemacht wird. In dem Fall war es auch nicht mal ein Angriff auf das Auto, der “spezielle Hardware “ benötigen würde.

So, yeah. Other than stated, Spotify does not provide 2FA (shame on them!), so I use a strong password and since years nothing happened.

This early morning I got multiple mails that my account was logged in from Brazil, from the USA, from India, and some other countries. There were songs liked and playlists created so it wasn’t a malicious e-mail but some people actually were able to log on to my Spotify account.

I of course changed the password and logged out all accounts and checked allowed apps, etc. and everything looks fine.

But I wonder … was there something that happened recently? The common sites to check such things do not list my old Spotify password, and a quick web research does not bring anything up.

Any clue what could have happened here?

Infomaniak claims to use TLS, but

The first link in the TLS chain is executed via a purely internal network by the webmail and Smtp servers and is not available in TLS for performance reasons.

is this normal, acceptable, irrelevant, standard, a red flag?

they are the biggest hosting provider of Switzerland, so I somehow have a hard time believing, they lack resources to implement TLS right.

The reporting methodology employed should yield valuable insights, spanning both technical details and high-level strategic considerations.

I wrote about my perception of what risks AI brings to society in 2024. And it's not all about cybersecurity 😉

Mozilla Foundation Security Advisory 2023-40

cross-posted from: https://infosec.pub/post/2466014

This is my first write-up, on a vulnerability I discovered in iTerm2 (RCE). Would love to hear opinions on this. I tried to make the writing engaging.

I only wonder because, while I know no one could advise per se that people deliberately make bad security decisions, I don't feel as a layman that the nature of the risk is adequately explained.

Specifically, if you use a really old OS or an old now unsupported phone. The explanations for why this is dangerous tend to focus on the mechanism by which it creates a security flaw (lack of patches, known hardware security flaws that can never be patched).

If we use an analogy of physical security whereby the goal is to prevent physical intrusion by thieves or various malicious actors, there's a gradient of risk that's going to depend a bit on things like who and where you are. If you live in a remote cabin in the woods and left your door open, that's bad, but probably less bad than in a high crime area in a dense city. Similarly, if you're a person of note or your house conspicuously demonstrates wealth, security would be more important than if it you're not and it doesn't.

I would think, where human beings are making conscious choices about targets for cybercrime some parralells would exist. If then, you turn on an old device that's long obsolete for the first time in years and connect to the internet with it, while I know you are theoretically at great risk because your doors and windows are essentially wide open, how risky is that exactly? If you just connect, at home on your wifi and don't do anything? Is someone inevitably going to immediately find and connect to this device and exploit it's vulnerabilities? Or does there have to be a degree of bad luck involved?

I've brought up the idea of malicious actors who are human beings making conscious decisions, (hackers), but I was once told the concern is more to do with automated means of finding such devices when they're exposed to the internet. This makes more sense since a theoretical hacker doesn't have to sit around all day just hoping someone in the world will use an outdated device and that they'll somehow see this activity and be able to exploit the situation, but I guess, it seems hard for me to imagine that such bots or automated means of scanning, even if running all day will somehow become aware the minute anyone, anywhere with an insecure device connects to the internet. Surely there has to be some degree coincidental happenstance where a bot is directed to scan for connections to a particular server, like a fake website posing as a bank or something? It just doesn't seem it could be practical otherwise.

If I'm at all accurate in my assumptions, it sounds then like there's a degree to which a random person, not well known enough to be a specific target, not running a website or online presence connecting an insecure device to the internet, while engaging in some risk for sure, isn't immediately going to suffer consequences without some sort of inciting incident. Like falling for a phishing scam, or a person specifically aware of them with mal intent trying to target them in particular. Is that right?

I know this may be a very general question, but there are so many resources I don't know where to start.

I'm afraid with the free TryHackMe plan I'm limiting myself a lot.

I know portswigger trining, is it better than TryHackMe?

Am I better off starting directly with CTFs? If yes, which is the best to use? (overthewire, hackthebox ...)

Is roadmap.sh reliable?

How important are the certificates? I am a tech illiterate but never cared about certificates.

Or as a last resort, is it better to start directly with hackthebox?
