Airtel launches Priority Postpaid with 5G network slicing in India

Airtel has launched Priority Postpaid, a new postpaid experience powered by 5G network slicing. The idea is to give eligible postpaid users a more stable and dependable connection during congestion, especially in crowded places like markets, traffic, concerts, stations, and busy urban areas.

Why SS7 Is Still One of Telecom’s Biggest Security Problems

SS7 was designed in an era when telecom networks trusted each other by default. That trust model is now one of the biggest weaknesses in global mobile infrastructure.

This post explains how attackers abuse SS7 for location tracking, SMS interception, call rerouting, and surveillance along with how the protocol actually works behind the scenes and why it still matters even in LTE/5G networks.

Mini Shai-Hulud worm hits npm supply chain, compromising 160+ packages via GitHub Actions cache poisoning

Mini Shai-Hulud has yet again reportedly compromised 160+ packages, including parts of the TanStack and Mistral ecosystems. The interesting part is the attack path: instead of simple typosquatting, it abused GitHub Actions cache poisoning and trusted publishing/OIDC workflows, making the malicious packages appear legitimately built and published.

Foxconn Wisconsin breach reportedly linked to Nitrogen ransomware, 8TB data theft claim

Foxconn’s Wisconsin facility outage being tied to the Nitrogen ransomware group after the gang added the company to its leak site and claimed theft of 8TB of data spanning over 11 million files. Foxconn has only confirmed a “technical issue” impacting IT systems and operations, but reports from employees point to a multi-day network disruption that affected production.

5G Network Slicing, Premium 5G and the Capacity Problem

5G network slicing sounds simple: create separate virtual lanes for normal users, premium users, enterprise traffic, low-latency services, or private connectivity on the same physical 5G network.

But in many parts of the world (especially in India), the issue is not just technology. It is capacity. If the shared network already has heavy traffic, limited indoor coverage, and constrained spectrum, giving one slice higher priority can directly affect regular users. That is where the net neutrality debate begins.

Slicing can work well for enterprise and specialized services, but consumer “premium 5G” becomes tricky unless operators first solve the capacity problem.

Starting a collaborative project on bypassing the new Google captcha

As we all know, Google is launching a new QR-based CAPTCHA / verification system and how badly it behaves on custom ROMs, unlocked bootloaders, rooted devices, and microG setups. A lot of legitimate users on LineageOS, PixelOS, crDroid, GrapheneOS, and other aftermarket ROMs are getting stuck in verification loops or failing checks entirely even when the devices are

otherwise secure and fully functional. Starting a collaborative project focused on understanding how the new flow works internally, what role Play Integrity and hardware attestation play, and exploring possible ways to make it function properly or potentially bypass ROM-related restrictions on custom ROM environments

for compatibility and interoperability purposes. Looking for Android reverse engineers, ROM maintainers, mobile security researchers, and modding enthusiasts interested in analyzing traffic flows, Play Services interactions, integrity checks, browser/app differences, and possible implementation weaknesses or workarounds.

Fake OpenAI Privacy Filter on Hugging Face Dropped a Rust Infostealer

A fake “OpenAI Privacy Filter” repo reportedly hit Hugging Face trending with around 244K downloads before being removed. It looked like a legit PII-redaction tool, but the Windows setup path allegedly dropped a Rust infostealer.

The chain abused trust signals pretty well: cloned docs, inflated downloads/likes, and a trending position. Once run, it fetched a remote payload, pushed for admin rights, created persistence via a fake Microsoft Edge update task, and weakened defenses by disabling AMSI/ETW and adding Defender exclusions.

The payload reportedly targeted browser passwords/cookies/cards, crypto wallets, Discord tokens, SSH keys, FTP/VPN configs, screenshots, and files containing words like “seed,” “secret,” and “password.”

Jio AirFiber Congestion Might Get Worse Over Time - Wi-Fi 5 C6/A6 Routers Could Become the Real Bottleneck

Anyone else noticing Jio AirFiber slowing down badly in dense areas? This breakdown explains why the older Wi-Fi 5 C6/A6 hardware inside many Jio AirFiber setups could become a major long-term bottleneck.. especially with more users joining the network and higher spectrum congestion. Good technical explanation of where the real problem starts: RF capacity vs local Wi-Fi limitations.

Critical Ollama Vulnerabilities: Memory Leak + Windows Updater RCE Risk

Ollama users should check recent disclosures around “Bleeding Llama,” an unauthenticated memory leak that may expose prompts, API keys, env variables, and other data from exposed Ollama servers. There are also separate Windows updater flaws that may allow persistent RCE through a malicious update chain. Worth updating, checking port 11434, avoiding public exposure, and disabling Windows auto-updates (for ollama) until fixed. More details linked.

cPanel & WHM Vulnerabilities Patched - DoS & Security Issues Could Affect Self-Hosted Labs and VPS Setups

Anyone running cPanel/WHM in a homelab, VPS, or self-hosted environment should probably patch soon. cPanel fixed multiple security vulnerabilities (on May 8) including denial-of-service related issues and other security risks that could impact exposed hosting panels (and one of them is cvss 9.8 and pretty easy to exploit). Since a lot of lab environments leave management panels internet-facing for convenience, this is one of those updates worth prioritizing.

Why mobile networks struggle in hotels, campuses, and crowded areas...even with full bars

A kinda detailed explainer on why mobile networks often become slow or unreliable in dense places like hotels, college campuses, malls, railway stations, and crowded areas. It covers the difference between coverage and capacity, indoor wall penetration loss, tower load, PRB/resource sharing, uplink congestion, SINR, backhaul limits, and why increasing signal strength alone does not always solve the problem

Airtel 5G SA real-world review: fast outdoors, weaker indoors?

Tested Airtel 5G SA in Kolkata using a Galaxy S26 Ultra, and the results were interesting. Outdoors, Airtel’s n78/3500 MHz layer performed really well, with speeds going up to 663 Mbps in my test and a peak of around 890 Mbps. But indoors, especially near the window, download dropped to 243 Mbps and upload fell sharply to 2.49 Mbps.

How Radio Waves Actually Carry Data - From Carrier Waves to 5G OFDM

Here's a beginner-friendly but technically grounded explainer on how radio waves carry data in real telecom systems. It starts with the basic idea of a carrier wave, then explains modulation, QPSK/QAM, OFDM in LTE/5G, antennas, SNR/SINR, adaptive modulation, and why “full signal bars” don’t always mean good data speed. The main point is that radio waves don’t “contain” data directly - telecom systems encode bits as controlled changes in amplitude, frequency, phase, and symbols, then recover them through signal processing at the receiver
