While the #CryptoWars continue, we would like to remind everyone of two very convincing facts for the pro #encryption side:

✅ 1. Encryption can't be outlawed

✅ 2. Backdoors for the good guys only are impossible

"Exploiting aCropalypse: Recovering Truncated PNGs"

My writeup on exploiting CVE-2023-21036 (un-cropping Android screenshots!)

Lol looks like JFrog finally disclosed CVE-2022-0668 [1]. @matthias_kaiser and I found that around a year ago, along with CVE-2022-0573 [2]. Coupled together we could unauth RCE Artifactory 🔥

Funny how they marked the RCE as being as severe as a blind SQLi, a “High”🤪

In neither case were we told the issues were fixed… 🙈🙉🙊

I wonder if Microsoft should meaningfully strengthen HTA files (not with SmartApps)… (yes, they definitely should) HT @campuscodi

Two vulnerabilities I disclosed to @msftsecresponse got patched today. https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-23415 and https://msrc.microsoft.com/update-guide/vulnerability/CVE-2023-23416. Both are are RCE and given critical severity. The first is a pre-auth vuln in ICMP.

From the bulletin:

How could an attacker exploit this vulnerability?

An attacker could send a low-level protocol error containing a fragmented IP packet inside another ICMP packet in its header to the target machine. To trigger the vulnerable code path, an application on the target must be bound to a raw socket.

Okay so everybody get ready to preemptively suspend the domain once we know what it is

> The app is codenamed P92

> The P92 app will support ActivityPub, MoneyControl reported

Major win for encryption.

European Data Protection Supervisor Wojciech Wiewiórowski said the indiscriminate scanning of private communications proposed by EU’s CSAM regulation “will always be illegal under the Charter of Fundamental Rights (and probably under several national constitutional laws as well),” https://www.euractiv.com/section/law-enforcement/news/eu-watchdog-online-child-abuse-draft-law-creates-illusion-of-legality/

lol, a way to bypass the Microsoft account requirement in Windows 11 - type username no@thankyou.com, any password, and it bumps you to local account creation.

BlackLotus Shows again: Revocation lists don't work, and Code Signing is not going to save you.

In #Hungarian we don't distinguish between "safety" and "security", which leads to confusions. I made this meme, but I'm not sure it's right.

Can some native #English speakers take a look? (clarification in alt text)

Kudos to Coinbase for publishing this fantastic write-up on social engineering. Really would love to see more orgs normalizing their wins (because make no mistake about it, this IS a win).

Is there a debugger I can "attach" by sideloading a DLL to the target? #antidebug #antiantidebug

Our (free) AWS Canarytokens have always been popular.

Today, we released the Azure alternative on our canarytokens.org server¹

Attackers who find ‘em have to use ‘em (and reveal their presence).
