soc.octade.net is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
⚠️ PHP CVE-2026-109618 & CVE-2026-109619 leaked before patch Two embargoed PHP vulnerabilities have leaked before fixes shipped (via Kevin Beaumont). No advisory, versions or CVSS yet. A release is expected this week.

The long term impact of this #eMudhra intermediate CA cert private key disclosure: It is now possible to perform TLS MiTM to millions and millions of older #IoT devices (or other devices that won't or can't get updated). The root certificate that has signed the affected intermediate certificate was added to trust stores in about beginning of 2019 (*). It expires only in 18-feb-2043.
This opens the avenue for all kinds of nasty things.
I saw the news about the compromised TLS certificates here on mastodon first.
Then I saw the jokes about "4" here.
But I had to search to find any coverage stating that "4" was literally the private key.
Here you go.
https://www.reddit.com/r/linux/comments/1xau81w/leaked_ssl_intermediate_certificates_https
"Edit: EM OV TLS CA - G3C has 4 as its private key. The number 4. 0x4."
And the detailed coverage that doesn't mention "4"

Ugh. Ampath patient records stolen in data breach: https://techcentral.co.za/ampath-breach-no-evidence-test-results-taken/287314/?utm_source=MastodonAfrica
If you've ever had blood work done in South Africa, chances are, Ampath has your details. :/
We don't often think of refrigeration as critical infrastructure, lest of all when we talk of 'cyber attacks' targeting the nuts and bolts of living.
But here we are reminded of this as legacy & unpatched network-enabled refrigeration units in over 300 supermarkets in France had their thermals attacked, raising temperatures internally (to the point of sparking fires in some cases), and spoiling food within them.
Perpetrator & rationale remain unknown.
Can anyone get me a linux-heavy blue team security job in Marquette or Sault Sainte Marie, Michigan?

Whenever anyone suggests using "AI" for anything technical or integrating it with any kind of pipeline, I am going to respond with:
> Okay, what is your plan on dealing with incubated ML exploits? You do know about incubated ML exploits, right?

🚨 Antino backdoor hides its commands in Outlook and OneDrive
Cisco Talos says the Antino Windows backdoor uses Microsoft Graph, Outlook mailboxes, and OneDrive for command-and-control, blending into trusted Microsoft 365 traffic.
The campaign also used a spoofed phishing email that reached its target despite failing DMARC, because the impersonated domain had a p=none policy.

NEWSCARD Publish and fetch permanent named records via Network News
Newscard creates a decentralized, encrypted, named record paste bin.
[git repo] https://codeberg.org/OCTADE/newscard (use most recent version only)
With a single command, name the card, snarf the file and encrypt it.
With another command, push the encrypted file to the public network.
With another short command, snarf a file from the network.
Only users knowing the name [key] of the record will be able to decrypt it.
If a strong passphrase is used to name the file, it will be very secure.
This is useful for quickly snarfing, encrypting, and publishing a text file:
$~: card enc [passphrase] [file]
$~: card put [passphrase]
It is useful for retrieving a text file with just a key:
$~: card get [passphrase]
$~: card show [passphrase]
If and when you want the general public to access the record just share the keyword.
Newscard uses nine (9) (NINE) layers of encryption with OpenSSL chacha20 cipher.
Newscard generates 9 each of: cipher keys, salts, key iteration parameters.
It would be nice if something like this were added to the ActivityPub protocol, such that keyword[@]host.url would do the same thing. Then secret text records could be stored securely for later retrieval or revelation.

I wish people would stop giving credit to "prominent cybersecurity/cryptography experts" just because they released some "cypherpunk" book or software of unproven impact 30 years ago and have since then retreated into golden tenure, writing technically empty but catchy preprints with provocative titles. These "Ludd grandpas" (you know at least a couple of names of who I'm referring to) are, unfortunately, still worshipped by a large number of semireligious followers, who contribute to the spread of their moldy ignorance.
Thinking deeper, maybe mine is a typical case of rejection for the image in the mirror: I hope I will never become like that in the future.
The world does not stop at your rants. Keep moving and stay open-minded, or become obsolete.
