wifi – What data does an ISP store?

Sorry to be so general, but I know that my ISP is recording connections to others and to everyone. I'm just wondering if they keep physical data via an HTTPS connection. Knowing how ISPs "also sniff packets", do they keep the data obtained by sniffing packets when they want to get a glimpse of the "journal"?

They keep a log of the data, so what can they see that has been done previously with respect to the data?

Thank you very much for your help <3

How can my ISP inject into this web page?

Lately, I've noticed that the pages I'm going on http Sometimes I have a big banner at the top of my provider. The funny thing is that when I refresh the pages, I get the https the site version and the banner are not there. I'm trying to type the http version in the address bar, but when I click enter, I get the https version. The Development Tools Network tab indicates that 301 people were permanently moved when setting up the http version and then I'm redirected the https version.

So I am a little surprised at how I got this banner. How is the ISP able to inject the banner + to display the site under the banner? See below screen capture. I would have assumed that the page was redirected https, that an ISP would not be able to display the page with a banner? What is happening here?

Note: My default DNS is 1.1.1.1 and 1.0.0.1 (both cloudflare)

An ISP does not recognize my PTR records and does not accept emails from my servers

Have 10 fps for outgoing e-mails with the correct DNS A and PTR records that match, and each provider has no problem receiving emails from our servers that use them. In fact, its server IP address rejects them (216.40.42.4), namely the email hosted by Tucows. Does anyone else have any problems with this IP address / provider?

All tested with the MX Toolbox and other DNS testers online and everything is correct. None of my IP addresses are on a blacklist. Google, Outlook and all other users have no problem receiving emails and I know that they all perform reverse tests for incoming mail traffic.

Really puzzled, because I think Tucows would take care of that. Someone else is affected or is it just me? Everyone knows a network support phone number for Tucows.

Error:
.hostedemail.com (216.40.42.4) refused to contact me: 450 4.7.1 Client host rejected: unable to find your reverse host name, (7x.xxx.xxx.xxxx)

Here are 2 addresses of my outgoing mail server and registration names:

efa148.webguyz.net – IP 72.249.59.148
efa154.webguyz.net – IP 72.249.59.154

How does DoH protect against ISP tracking?

It looks like a modern Internet service provider would already have a basic level of packet inspection to identify outgoing TCP connections, even if it only serves for shaping traffic or operator level network address translation, and maintaining a reverse lookup does not seem overly expensive.

bot – I run an indexing robot on my localhost computer, can my ISP detect it?

I'm using a 100 GB internet bandwidth package per month at my ISP. I've created a simple web crawler for fun and I run it on my personal computer 24 hours a day, 7 days a week. The robot is exploring all the bandwidth and I'm I have configured not to download media files (images, videos, audio files), so as to be able to make as many requests as to collect as many HTML pages as possible.

I do not know how ISPs work. Do they record the number of requests? or just bandwidth?

Can my ISP detect this? Or will they see me as a normal user who is asking too much above average?

botnet – E-mail received from the ISP stating that one of my devices is infected with malware

My father received a suspicious email from our ISP (mtnl.net.in)
The email came from noreply@mtnl.net.in and it contained our user ID (xxxxxxxx @ a i was hiding it) in the email, so it had to come from the ISP itself.

Details of the e-mail below:

Subject:

"Intimation about systems infected by malware / viruses"

Body:

Dear Sir/Madam,
Greetings!
It is observed that your device connected with MTNL Mumbai broadband network with broadband number xxxxxxxx@a is infected with Malware. This is as per the analysis of Computer Emergency Response Team -INDIA (Cert-IN), under the Ministry of Electronics and Information Technology.
Malware (CNC) is unwanted software that is installed in users system without users consent while user is surfing on the Internet. An attacker or cybercriminal can remotely send commands to such systems which are compromised by malware. These compromised machines can be used to create powerful networks (botnet) of infected devices capable of carrying out distributed denial-of-service (DDoS) attacks, stealing data, deleting data or encrypting data in order to carry out an extortion scheme.
The device becomes part of the botnet due to malware/virus installed on it.
To secure your devices , Kindly check your devices for malware/ botnet using Antivirus S/w.
For more information on malware/botnets and the counter measures kindly visit https://www.cyberswachhtakendra.gov.in. You can also download "Free botnet removal tools".
Thanks & Warm Regards,
MTNL, Mumbai

I've extracted all the links from the email and scanned them via the https://www.virustotal.com/ url scanner, but all have been reported as safe.

Connections:

Looking online, there is a similar question about Quora but a different scenario.

NETWORK AT HOME

  • Two mobile phones (Android)
  • A laptop (Windows 10 with antivirus Avira)

QUESTION:

How do I know if the cyber protection offered by my ISP is worth it? [on hold]

My ISP offers a "cyber-protection" service for an additional fee. They say it "identifies and blocks attacks on privacy, credit card scams, identity theft and hacker attacks against computers connected to your home network", but does not do not say how they do it.

Can I test to see if their cyber protection is worth it, or maybe I should look elsewhere for cyber protection?

tls – Does the DNS change help prevent MITM at the ISP?

A few days ago, the Government of Kazakhstan passed a law allowing it to apply with the help of SSL certificates signed by the government all https traffic from all (or almost) Internet Service Providers. For example, when you visit https://google.com, your browser warns you that the certificate is not approved and that you must trust these certificates or install them manually.

In short, you use government-issued certificates to encrypt your traffic, which is then decrypted again at the ISP level to be encrypted again by the service provider. original certificates (valid) before being sent to the websites you access. Which basically means that ISPs can do what they want with your data as if you were using HTTP from the beginning.

As far as I know, one solution would be to use a trusted VPN service. However, this greatly aggravates the experience of use and essentially requires you to trust the VPN provider (that the majority does not care to check).

So my question is: if I had to change my DNS to say, 1.1.1.1 by Cloudflare, will it prevent my ISP from acting as an intermediary?

Edit: if that does not help, what can I do to protect my privacy?

can a top ofric of isp access my information from my IP address

Suppose that a rich person knows my ip. Can a rich person pay a senior official working in an Internet provider to give him the name and information about the owner of that IP address? suppose the official is the friend of the rich people. can he find information about the owner of this IP address and give it to the rich man? Is not it illegal? I have read that it is illegal to give information to anyone without a police warrant. so the official will do it illegally when he gives it. but my question is: can the official find the information? And if he can, will he find out and put it back? or is it out of reach and very expensive and difficult? ignore the errors in the question and answer me. how difficult is it for an ISP official to access the info?
