(AA) \"Counterfeit telecommunications device\" means a telecommunications device that, alone or with another telecommunications device, has been altered, constructed, manufactured, or programmed to acquire, intercept, receive, or otherwise facilitate the use of a telecommunications service or information service without the authority or consent of the provider of the telecommunications service or information service. \"Counterfeit telecommunications device\" includes, but is not limited to, a clone telephone, clone microchip, tumbler telephone, or tumbler microchip; a wireless scanning device capable of acquiring, intercepting, receiving, or otherwise facilitating the use of telecommunications service or information service without immediate detection; or a device, equipment, hardware, or software designed for, or capable of, altering or changing the electronic serial number in a wireless telephone.
One solution that should give you these would be to use a public key signing scheme. Start with a \"system hash\" (say grab the macs on any NICs, sorted, and the CPU-ID info, plus some other stuff, concatenate it all together and take an MD5 of the result (you really don't want to be handling personally identifiable information if you don't have to)) append the CD's serial number and refuse to boot unless some registry key (or some datafile) has a valid signature for the blob. The user activates the program by shipping the blob to you and you ship back the signature.
Potential issues include that you are offering to sign practically anything so you need to assume someone will run a chosen plain text and/or chosen ciphertext attacks. That can be mitigated by checking the serial number provided and refusing to handle request from invalid ones as well as refusing to handle more than a given number of queries from a given s/n in an interval (say 2 per year)
A good software license key/serial number generator consists of more than just a string of random characters or a value from some curve generator. Using a limited alphanumeric alphabet, data can be embedded into a short string (e.g. XXXX-XXXX-XXXX-XXXX) that includes all kinds of useful information such as:
Most secure schemes involve either the user providing the software supplier with some details of the machine which will run the software (cpu serial numbers, mac addresses, Ip address etc.), or, require online access to register the software on the suppliers website and in return receive an activitation token. The first option requires a lot of manual administration and is only worth it for very high value software, the, second option can be spoofed and is absolutly infuriating if you have limited network access or you are stuck behind a firewall.
You don't need to go into dev mode to wipe the admin off the machine. All you have to do is do a power wash. If the device is controlled by an admin that's a different story. You would have to contact the company that is controlling the machine and have them release the device. If your tech-savvy you can change the serial number on the device which will break the admin control but it is risky and you risk destroying the board.
READ: This is coming from someone who bypassed the web filter, printed from school printers on a personal laptop by finding the IP address, got past a local IP internet block multiple times and was left alone by admin and IT after a few years. The enterprise lock (and device policies) is stored on the cloud and tied to the device's serial number. Without access to the administration panel, there is no way to remove the admin tie without a new motherboard! You might as well replace the Chromebook since motherboards vs. whole units end up being similar if the admin will not remove the enterprise tie.I know this is going to come up, so I'm addressing it: The screw trick DOES NOT WORK ON ANYTHING NEWER THEN THE \"CR-48 SERIES\", WHICH ARE ALL DECOMMISSIONED DUE TO THE FACT THEY NO LONGER GET UPDATES AFTER 5+ YEARS! UNLESS THE SCHOOL CANNOT AFFORD NEW CHROMEBOOKS (literally impossible since they get state funding and block XXX sites anyone who went through puberty knows about), they replaced them with PATCHED UNITS.
even if you were a god hacker person you would trip the IT department of youre school since it will show that youre s/n(Serial number) thats different on every chromebook as offline if youre tech savvy you can change the chromebooks motherboard which the serial number is stored in you can in theory turn the chromebook normal but the school will probably try track the chromebook down in order to force you to pay for it or to take it back, so probably not a good idea to try this.
3) This is the ass kicker of them all...all those policies I just mentioned AREN'T tied to the firmware, the BIOS, or any of that (well they are but you'll see what I mean). They're all tied to your serial number. When you reset your Chromebook, go through the GUI Setup process, and right before the enrollment screen you see \"Determining device configuration\"...that's Google checking in with it's servers to see if your device is managed by a domain. So that's really hard to bypass. I can give you all a few extra suggestions to try, but don't get your hopes up. It's also just a policy called \"Forced Re-Enroll\" in the Admin Console. These things have security tighter than a bug's ass, but I guess that's why all of our G Suite admins are laughing at us right now, me included.
Hey there. Sorry if this is a duplicate post, I think my last one got deleted because I had to create an account. I have an HP Chromebook 14 G4 that was issued by my last job. I'm allowed to keep this one, but with enrollment it does me no good because I no longer have the token key from the little device they gave me 2 login. Also, it's very limited as to what you can install so I'm trying to wipe it. I was able to get through all of these steps including developer mode and confirm the product serial number changed. The device is still managed however. I think I may have chosen the wrong screw possibly I also did not see a sticker around the copper, only a circle of silver dots on it. It almost looks like Braille. the Skrill remove was the only one that had a copper plate that was parsed in different sections. After looking at diagrams online I did not find a picture that looked anything like the inside of this laptop. Thoughts
Alright so i hate to break it to all of you 6th/7th/8th graders but enrolled devices CANNOT BE BYPASSED it is tied to the chromebooks S/N meaning even if you do bypass it. It will connect to the district servers and find the computers serial number and force enroll it and bring you back down to where you started, unless you get into a admins console and untie the desired chromebook which would be hard unless you knew youre devices serial number. and even if you were tech savvy and changed the devices Serial number YOU WOULD BE CAUGHT, Because you would trip youre districts IT department they track all the chromebook serial numbers so moral of the story just dont even bother trying to bypass the restrictions.
Serial Keys Generator is an online hacking tool, not to be confused with serial key generators. Unlike most other methods available, Serial Keys Generator is not software. Instead, this is a free online tool with nothing to download.
PortMonv3.03 (January 12, 2012)Monitor serial and parallel port activity with this advanced monitoringtool. It knows about all standard serial and parallel IOCTLs and evenshows you a portion of the data being sent and received. Version 3.x haspowerful new UI enhancements and advanced filtering capabilities.
Proof you now own the device. An email, iMessage, or other documentation from the original owner is helpful. Similarly, if you purchased the device from an online marketplace, being able to show you purchased it legally may help your case. In either scenario, be sure you can verify the full details of the device, like its serial number. 153554b96e
