Validating Telegram Mini App initData in PHP
This tutorial provides a step-by-step guide on securely validating Telegram Mini App initData in PHP. It covers parsing the raw query string, constructing the data_check_string, deriving the secret key via HMAC-SHA-256, performing timing-safe comparisons with hash_equals, and checking auth_date expiry. The article includes code examples and production hardening tips such as rate limiting, validating user shape, and avoiding logging sensitive data. The guide is intended for developers building Telegram Mini Apps and emphasizes treating initData as untrusted input.
- initData is parsed as a query string, with hash removed and remaining pairs sorted by key.
- The secret key is HMAC-SHA-256 of the string 'WebAppData' with the bot token, used as the HMAC key.
- Timing-safe comparison using hash_equals is required to prevent timing attacks.

WhatsApp strengthens account security with passkeys
Meta announced expanded WhatsApp account-security updates that add multiple passkeys per account, replace six-digit two-step verification PINs with longer alphanumeric passwords that allow letters, numbers and special characters, and provide richer incoming-call context (caller country/origin, WhatsApp nickname and whether you share a group), initially on Android. Passkeys enable biometric sign-in via Face ID or fingerprint and build on passkey support introduced in 2024; over one billion accounts have already added a passkey. WhatsApp says its end-to-end encryption protects more than three billion users. The features, described in a WhatsApp blog post and rolling out gradually alongside other changes (usernames and a paid “WhatsApp Plus” tier), aim to reduce phishing and account takeovers and align WhatsApp’s authentication with peers such as Signal and Telegram.
- WhatsApp is rolling out three security features: multiple passkeys per account; full alphanumeric two-step verification passwords with special characters replacing six-digit PINs; and richer incoming-call context (caller origin, WhatsApp nickname, and shared-group status), initially on Android.
- Passkeys support biometric sign-in (Face ID or fingerprint), build on passkey support introduced in 2024, and can be added to multiple devices/accounts.
- WhatsApp’s end-to-end encryption protects more than three billion users, and over one billion accounts have already added a passkey.

Build a Personal AI-Powered Feed via Telegram
A Dev.to author outlines a simple how-to for escaping social media algorithms by creating a personal feed using AI automation and Telegram. The proposed approach: pick creators you value, use AI to monitor when they publish new videos, and have the AI forward new content to a Telegram bot for download. The author cites Abo Ziad (inspired by Ali Abdaal) as the idea source and plans to try the workflow for one month and report back. The post is a short practical guide rather than a technical deep dive or product announcement.
- The article recommends using Telegram combined with AI automation to build a personal, algorithm-free feed.
- Recommended workflow: choose preferred creators, use AI to monitor new video publishes, and send new videos to a Telegram bot for download.
- The author credits Abo Ziad (compared to Ali Abdaal) as the inspiration for the idea.

AI Bots Waste Scammers' Time to Combat Fraud
Australian security firm Apate has developed an AI-powered system using approximately 350,000 bots to combat telephone and messaging scams. These bots engage scammers in lengthy conversations, impersonating various personalities to waste their time and reduce the time available to target real victims. Some conversations last over two hours. The AI agents also infiltrate scam groups online, collecting over 250,000 pieces of intelligence on fraudulent activities and responsible individuals, including bank account details. CEO Dali Kafaar stated that every minute a scammer talks to a bot potentially protects hundreds or thousands of people from being contacted by the same scammer. Despite these efforts, the scale of the problem is immense, with an estimated 68 billion scam calls worldwide annually. The bots represent a novel approach to fighting fraud using AI.
- Apate has deployed ~350,000 AI bots to engage and waste scammers' time.

India Mandates Caller-ID Apps Share Spam Reports with Telcos
India's telecom regulator, TRAI, has amended rules to require caller-ID and call-management apps, such as Truecaller, to share user spam reports with telecom operators via a blockchain-based platform. The move aims to broaden the spam report pool for enforcement. Truecaller, which has over 500 million monthly active users globally and 350 million in India, called the requirement anti-competitive, citing a one-way exchange of valuable data. The amendments also bring AI-powered and automated calls under the A2P framework, requiring declaration to operators or being treated as spam. Telecom operators may levy termination charges up to 5 paise per minute. The rules raise questions about data sharing scope, enforcement, and consent. India reported around 42 billion spam calls in 2025, with Truecaller blocking 12 billion.
