Is my understanding how of a secure connection is made using PKI correct? [duplicate]

My understanding as as follows:

Client requests a secure connection with a Website’s Server

Server provides a certificate with the address of the server and public key of the server encrypted with a Certificate Authority’s (CA’s) private key.

Client then decrypts that certificate with the public key of the CA which is packed with the OS/browser and verifies it is an authentic certificate from the CA which has not been decommissioned. The client now knows we can trust the server.

Client then provides their public key encrypted with the server’s public key.

The two can now communicate securely with the data sent from the client being encrypted with the public key of the server and decrypted by the server with the private key of the server and with the data sent from the server being encrypted with the public key of the client and decrypted by the client with the private key of the client.

Since the private keys are kept private and not distributed even if some malicious agent gets hold of the encrypted data traffic since it was encrypted with the public key they cannot decrypt any of it unless they have somehow got hold of one of the private keys.

Is this understanding correct?

Instagram Phishing: “Look – I Made This Just For You – Click Here”

I manage a somewhat popular Instagram page with ~5000 followers.

Recently I’ve been getting a ton of the exact same direct message from various followers:


I Made This Just For You – Click Here

This took me about 2 hours to make. They came out really nice. I hope you love them.

I just made this for you, I hope u like it.

instagram phishing

They’re all people who have legitimately messaged us in the past. In some cases the usernames have been recently changed and/or the account’s pictures have been deleted.

The link contained in the message is:

The url also has a &ure= parameter that maps to a resource. This seems to be how they bring up the account’s profile page on the fake login screen.

How are these Instagram accounts being hacked?

What is the goal in sending our account these direct messages? What happens if you are unfortunate enough to click the link?

We’re being careful with DM links and two-factor authentication is enabled for this account.

How can we prevent these spam messages?

Is there anything we can do to safeguard or report our hacked followers?

Is it possible a scammer stole my credit card details and made a new card from it?

So I’m abroad at the moment, yet I’ve just had a cash withdrawal made on my credit card from my country of origin, even though I’m not there and the card IS with me abroad.

I called the card issuer and they have cancelled the card and are sending me a replacement. They told me that this was definitely a bank machine withdrawal with a physical card so my card must have been copied at some point.

What’s odd is that it’s actually months since I last used this card in a physical transaction back in my home country so it’s odd that if it was copied all the way back then that it’s only being tested now.

Anyhow, it got me thinking, is it possible that the card wasn’t copied some months back but instead a copy card was compiled using data a scammer obtained about my card and its security codes via another source such as an online shop ? Is that technically possible or is there info in the card that is required that isn’t ever part of an online transaction?

I made up a password a few years ago for a customer – [closed]

The password was lost and darned if I would remember it. I exported the config file from my phone which I can still use to login using the saved password but that doesn’t help him login cause I can’t retrieve the password.

Looks like Hex and I believe it contained ashley

there is no password reset available and the customer would have to pay to have the machine reprogrammed from scratch if I can’t figure it out.

any thoughts?

Limit amount of posts made within a custom taxonomy

Is there a way to limit the number of posts that can be created within a custom taxonomy?

I have a custom post type called Preferred Agents and a custom taxonomy called Agent Location. I want to be able to limit the amount of Preferred Agents in an Agent Location to only 3. Is this possible?

Any help is appreciated! Thanks.

[ Insurance ] Open Question : If parents take out whole life insurance on their kids, then die first, shouldn’t someone get some cash back for the years of payments made?

The cover page says each child was insured for $ 5K, ‘whole life paid up at age 65’ with number of years payable at 54 (for the child that was 11 when the policy started) with annual premiums of $ 53.30. Isn’t the purpose of ‘whole life’ policies that it’s like an investment? Parents are most likely to die first, so of course their payments would stop before the kids ever reach 65. Is the policy worthless when payments stop? This seems like a bad, ill-advised deal if no one gets money back.   It doesn’t make sense to me that any LONG TERM policy should cancel just because a person was unable to make payments for a temporary period of time, like after getting laid off from work, disabled, death of a spouse, etc. It would be no wonder insurance companies make so much money if they get to keep all the money they taken in for many years from people who will never file a claim before they stop making payments for whatever reason.
