All encryption is applying masks and applying XOR operations Or using an S- box or Substitution box. Which is a 2D substitution table originally invented by Kaisa Nyberg. It cannot be banned otherwise almost nothing will work in Denmark. Bitwise circular shifts and Bitwise XORs are the only operations utilized in AES-256. This massive intervention by Danish govt.

📶 Bluejacking, Bluesnarfing, and Beyond Cybercriminals have terms for exploiting Bluetooth: Bluejacking → sending unsolicited messages Bluesnarfing → stealing data without consent Bluebugging → taking full control of a device ➡️ Tip: Keep your phone in non-discoverable mode so strangers can’t even see it’s available.

🔒 At CryptPad, we’ve said it before and we’ll say it again: #ChatControl would be a disaster for privacy 15 EU member states now back this proposal, despite experts warning it would put everyone at risk while doing little to protect children. Client-side scanning would force providers to break end-to-end encryption and scan private content on personal devices. 📢 That’s why we welcome the launch of Fight Chat Control (https://lnkd.in/dsb8-MUM), a resource to understand the dangers and contact your representatives. If you live in the EU, your voice matters. Please reach out to your Member of the European Parliament (MEP) and ask them to oppose it, especially if your country currently supports Chat Control. 👉 More context in our original article: https://lnkd.in/dMPAJW_5 #CryptPad #PrivacyFirst #Encryption #DigitalSovereignty #Stop #ChatControl

Okay, chat monitoring will help find some criminals, but others will have no problem finding ways to continue communicating undetected, anonymously, and encrypted. Much worse is the fact that the “back doors” open up new avenues for criminal activity. In the end, the losers will be “normal” citizens or companies that depend on secure and confidential communication.

#ChatControl vs #EndToEnd encryption Is your data sent via end-to-end encryption really safe?! WhatsApp promotes end-to-end encryption as “unbreakable,” but the trick isn’t breaking it—it’s bypassing it. By grabbing data before it enters the secure tunnel or right after it leaves, #ChatControl could access messages directly on your device. So even with the best security, your chats may still be exposed 😉.

🛑💸 Data access and subscriptions are the primary sources of revenue for mobile networks. In mobile, data access can be zero-rated to support education, social, and governmental sites, as well as specific protocols such as DNS. This type of access can be exploited by fraudsters to effectively obtain “free” data from both MNOs and MVNOs—by faking protocol and application signatures, and by targeting gaps in the charging, auditing, and security checks of telcos. Revenue from gigabytes of data access can be lost, and attacks are often shared online as fraudsters become more sophisticated.

TL;DR: The EU is about to vote on Chat Control, a law that could end encrypted private messaging. https://lnkd.in/gy-Y7eTa makes it easy to take action before September 12. I don’t usually post about politics, but this one hits close to home. The EU’s proposed Chat Control law would mean that every message, photo, or file we share could be scanned, no matter who we are, or what we’re doing. That’s not just bad for privacy, it’s dangerous for security, trust, and freedom of expression. FightChatControl.eu explains the risks, shows where each country stands, and even helps you contact your representatives directly. As of now, only a handful of Member States are pushing back, and the final vote is just days away. Whether you work in tech, law, or just care about your right to private communication, this is the moment to pay attention. Encryption is one of the last defenses we have for secure digital life, once it’s gone, it’s gone. Take a few minutes, check the site, and speak up while there’s still time. #Privacy #Encryption #DigitalRights #CyberSecurity #FightChatControl #StopChatControl #DataProtection #DigitalFreedom #PrivacyMatters #EUlaw
