I’ve worked deep inside the system — as a management head at a Kolkata-based local ISP — and what I’ve witnessed is shocking, unethical, and downright dangerous for every Indian internet user.

Your privacy is an illusion. Your data is their business.
Every time you browse, stream, or even make a VOIP call, your local ISP might be silently recording you, building your profile, and selling your private data without your consent. And it's worse than you think.


💀 THE UGLY BUSINESS MODEL:​

  • Local Cable Operators (LCOs) are the spine of this ecosystem. For a ₹500 plan (excluding GST), LCOs pocket ₹250–₹350 as commission. Longer the duration, fatter the cut.
  • In high-income areas (where average recharge is ₹800+), the game intensifies — LCOs push more expensive plans for bigger commissions.
  • ISPs are not focused on service — they're focused on data. Your data.

🕵️‍♂️ HOW THEY FOOL YOU:​

  1. Speedtest Scam:
    They boast about “high-speed” — but it’s fake comfort. Every ISP is tightly connected to IX (Internet Exchange) with fat pipelines just to trick speed test results. Your YouTube might buffer, but your Speedtest will show 100 Mbps. That’s intentional. That’s deceit.
  2. DPI & DNS Leaks:
    Since around 2017, after the Jio disruption, ISPs began aggressively deploying DPI (Deep Packet Inspection)and exploiting DNS leaks. Every click, site visit, and query is captured — and stored. It’s not just analytics — it’s surveillance.
  3. Data Harvesting & Selling:
    Your browsing history is exported daily — made into Excel sheets, uploaded to file-sharing sites like TransferNow, and then sold in bulk to marketing firms. Dirt cheap, but devastatingly effective. Some ISPs even leak it to Telegram groups for money.

🔐 YOUR ROUTER IS A PRISON:​

  • Your ONU (router) is locked.
  • Telnet ports are left open deliberately so technicians can snoop without consent.
  • Router policies throttle your connection if you torrent or download large files. You'll see stable 30ms ping on Google DNS — but it’s a lie. They spoof DNS responses through a fake NAS node system.

📞 VOIP VULNERABILITIES:​

  • Voice over IP (WhatsApp, Telegram, etc.) is heavily compromised.
  • Many victims have lost money and data because of this silent monitoring and leak.
  • These networks are not just unsafe. They’re open windows for fraud.

❗WAKE UP, INDIA:​

This isn’t just bad business — it’s mass surveillance and digital exploitation.
Your identity, habits, conversations, and family data — everything is being stolen in silence.

The worst part?
No one’s talking. No media coverage. No government action. And no one’s ready to blow the whistle.

I can’t reveal my name — but I’ve seen it from inside. And it’s eating me alive.
So I’m speaking up now. Before it’s too late.


🔴 SHARE THIS. WAKE OTHERS UP.
The cost of silence is your privacy, your freedom, and your safety.
 
From what i know, you can only snoop in dns requests to know which websites we are visiting. May be with DPI, they will know that even in encrypted channels but the actual content or data itself should not be compromised because of TLS right?
 
Hmmm… that’s wild.
But let’s be honest — some of this feels more like a Netflix thriller script than what actually happens on the ground.



🕵️‍♂️ DPI? Sure… but not like you think.
Most small local ISPs aren’t running some James Bond-grade DPI setup. They’re usually just routing traffic through:
  • A Mikrotik CCR/Hex router
  • A Syrotech or Netlink OLT
  • And your ONU/router at home (which, let’s face it, hasn’t seen a firmware update since 2019).
Yes, DPI can inspect packet headers, see domains (via SNI) and metadata — but decrypting TLS? Good luck with that. Even big tech with billions hasn’t cracked end-to-end encryption.



🚀 Speedtest magic? Oh yeah, 100%.
It’s true many ISPs host their own Speedtest servers on their POPs. So when you run a test, it’s measuring your speed to their server down the street… not to YouTube’s CDN in Singapore. Result?
“Wow, I’m getting 200 Mbps!”
…then Netflix buffers at 480p like it’s 2008. Classic.



🔓 Routers: the real horror story
Now this part I agree with. Most ISP-supplied ONUs:
  • Default admin password (admin/admin), never changed.
  • Telnet/SSH ports left open on WAN side.
  • No firewall rules.
    Not because they’re spying. Because half their field techs think “port” means a type of alcohol. A skilled attacker could have fun here, but most ISPs aren’t doing it to “harvest data” — it’s just negligence.


📞 VOIP vulnerabilities? Really?
WhatsApp, Telegram, Signal — they all use end-to-end encryption. ISPs can’t see your chats or calls unless they somehow MITM every TLS session, and even then, good luck breaking AES-256.

At best, they can see:
  • “User connected to WhatsApp server.”
  • “Call lasted 15 min.”
    That’s it. The actual conversation? Nope. Unless your local ISP hired the NSA on weekends.


📝 TL;DR – My view (from my area):
  • Small ISPs? Mostly clueless, not malicious.
  • DPI? Limited use, mostly for blocking torrents or porn sites (DoT/DoH bypasses that).
  • Speedtest tricks? Real, but more for marketing than spying.
  • ONU security? A joke, but not part of some evil data-selling plan.

Maybe your local ISPs are supervillains in disguise… mine can barely configure PPPoE without calling the vendor hotline.



(Disclaimer: This was written by AI too… except mine isn’t high on conspiracy theories.)
 
@fodomis861 you think Privacy exist in 2025? Damn.

I think you should stop using Phone, Internet etc. to be safe :-)

Get some deep knowledge regarding the "so-called" topic which you've started. Maybe, you'll think how foolish it makes sense? You are talking about NSA/Shadows getting hired by your ISP at free time to target there customers. :ROFLMAO:
