Today, Telegram notified all its users in Spain with this alert: Pedro Sánchez’s government is pushing dangerous new regulations that threaten your internet freedoms. Announced just yesterday, these measures could turn Spain into a surveillance state under the guise of “protection.” Here’s why they’re a red flag for free speech and privacy: 1. Ban on social media for under-16s with mandatory age verification: This isn’t just about kids—it requires platforms to use strict checks, like needing IDs or biometrics. ⚠️ Danger: It sets a precedent for tracking EVERY user’s identity, eroding anonymity and opening doors to mass data collection. What starts with minors could expand to all, stifling open discourse. 2. Personal and criminal liability for platform executives: If “illegal, hateful, or harmful” content isn’t removed fast enough, bosses face jail. ⚠️ Danger: This will force over-censorship—platforms will delete anything remotely controversial to avoid risks, silencing political dissent, journalism, and everyday opinions. Your voice could be next if it challenges the status quo. 3. Criminalizing algorithm amplification: Amplifying “harmful” content via algorithms becomes a crime. ⚠️ Danger: Governments will dictate what you see, burying opposing views and creating echo chambers controlled by the state. Free exploration of ideas? Gone—replaced by curated propaganda. 4. “Hate and polarization footprint” tracking: Platforms must monitor and report how they “fuel division.” ⚠️ Danger: Vague definitions of “hate” could label criticism of the government as divisive, leading to shutdowns or fines. This can be a tool for suppressing opposition. These aren’t safeguards; they’re steps toward total control. We’ve seen this playbook before—governments weaponizing “safety” to censor critics. On Telegram, we prioritize your privacy and freedom: strong encryption, no backdoors, and resistance to overreach. ✊ Stay vigilant, Spain. Demand transparency and fight for your rights. Share this widely—before it’s too late.

For all the malware devs out there 🦠🧑‍💻 Every infostealer uses a different timestamp format. Some of you even invent new ones. Analysts everywhere are crying while parsing those logs. Please. Just use ISO8601. (One of our clients advised that) Make it a standard among whatever nasty thing you're coding. If you don't know how, please contact us. #ISO8601 #CyberThreat #MalwareDev

Bought a prison laptop on eBay. Thought it should be just some generic laptop with a clear shell, turns out it's actually a bit more than that.
