This means that Apple has the coarse location track log (due to GeoIP of the client IP) for every M1 serial number. When you open the App Store app, that serial number is also sent and associated with your Apple ID (email/phone) if you log in.
HackerOne first reported the vulnerability back in January, which allowed anyone to enter a phone number or email address, and then find the associated twitterID. This is an internal identifier used by Twitter, but can be readily converted to a Twitter handle.
Serial Number Twitter Hack Pro
This recall involves 13 models of Frigidaire refrigerators and one Electrolux model refrigerator. The refrigerators all feature an ice maker and come in stainless steel, white and black. The brand name, model and serial number for each unit is printed on a label located on the right panel in the interior of the refrigerator compartment. The refrigerators range from 23 to 36 inches wide.
While Twitter did not confirm the number of accounts affected, media reports citing hackers said that the profile details, including email addresses and phone numbers, of 5.4 million users had been shared for free on a hacker forum as recently as November 24.
In a move that would surely impress Nancy Drew, the brainy blond decided to contact Tampax manufacturer Procter & Gamble and send Tampax the serial number on the box to find out when the tampon was made.

The easiest way is to create a paid macOS app is to simply put a price tag in the App Store, but it's a common practice nowadays to provide a free download that can later be upgraded to a pro version. In this article, we'll use our knowledge of serial numbers and asymmetric cryptography to create license files that cannot be reverse-engineered and use them to activate an app's premium features.
A simple way to achieve this is to provide serial numbers -- a system in which a user of the app can purchase one of these numbers and input it into the app to unlock its premium features. But how do you know the code is legitimate? Is it possible to confirm that the code was 100%, without a shadow of a doubt, provided by you, and not faked by someone who reverse-engineered the logic?
In the mid-2000s, serial numbers were a very common way to validate purchases, and every software/game you bought from a store would come with a serial number in the box which you had to input when installing it to prove that you were in possession of a legitimate copy of the software. However, serial numbers at the time were also very flawed. The validation logic was often some sort of hash function that was calculated on top of the serial number, and because this all happened offline, it wasn't very hard for a hacker to decompile the software and find out what this logic was. In fact, decompilers like Hopper nowadays are so good that they can even convert the decompiled assembly code into a pretty readable pseudo C code, making it pretty easy to figure out how an app works. Hackers would then use this logic to create keygens that could produce fake serial numbers that these apps would naively accept as being legitimate. If you ever pirated anything from the time, you definitely used one of these!
Fortunately, with modern cryptography, the serial number system has been since replaced by a much more secure system that is practically impossible to break. Let's see how it works and how to implement one in Swift.
As we've seen above, the biggest flaw in serial number systems is that the validation logic could simply be reverse engineered and reproduced to generate fake keys that the apps would think are legit. This seems like a dead-end scenario because we absolutely can't prevent the app from being reverse engineered, but we actually can prevent the reverse-engineered logic from being reproduced.
The system we'll implement in this article is called a digital signature, and it works around asymmetric encryption (private/public key). Digital signatures work by providing some arbitrary data (for example, the name of the person who purchased the license) and a serial number, which we'll now call a signature. This signature was created by encrypting that data with one of the keys, and by inputting both the data and the signature into the app, the app can validate it by decrypting the signature with the other key of the pair and checking that the resulting value is equal to the accompanying data.
I tried to update the serial number and had no problem building the PJL file, but was unable to successfully transfer it to the printer itself. I'm not well versed with this and received a notice indicating that I was "missing hostname and port". It wasn't hard to follow the other instructions to build the file. I'm just missing something when it comes to transferring it.
@Jerrykur - Nope. It's purely cosmetic since everyone's printer is out of warranty at this point. The serial number on the replacement board won't match the serial number on the back of the printer. Since it only took 5 minutes to update the printer (longer to write the PJL file than to perform the actual update), I went ahead and did it.
It seems that HP does not monitor (or does not respond potentially more accurately) these forums and while Repairatrooper is being at trooper offering suggestions, we really need HP involvement. While i don't know about the class action legal option someone proposed, given how difficult HP makes it to reach a human through their support website and their useless help bot, I've at least gotten human replies badgering them on Twitter DM's. I suggest (request) you consider trying this route (regardless of your current feelings about twitter's new ownership), trying to complain there or at least get their marketing group's eyes on our plight and maybe with enough people highlighting the same model number and firmware update maybe this can make it to someone's desk. I know, keep dreaming, but just a suggestion.
