I have this in mind few weeks ago to create a topic about kyc on exchanges, but not limited to exchanges but all other platforms that enforce kyc before users can be able to have access to their products and services.
Note that buying verified account can lead to scam, I mean the account seller can scam you. Also the account can be blocked and require you to prove you are the real owner which can lead to money loss. Also know that the online criminals are are the ones that know the way to go about this as they are smart enough to fulfill their mission before anything suspicious surface. Also know that your bitcoin and other funds on centralized exchanges are not yours on blockchain, you have no full control over your own coins, the exchange has the full control.
Kyc is extremely dangerous, but not to the bad actors as they are the criminals making use of fake information for kyc purpose and they are using it for fraudulent activities. So, the good people are just collateral damage of the bad actors fraudulent activities while the bad actors are still seeing successful solutions to execute their plans. To know more about this, you can read the below article about how the bad actors still able to make use of fake verification.
For $200, You Can Trade Crypto With a Fake ID“It’s a vulnerability KYC systems have. If you know how to generate [synthetic] data, you use it. KYC systems are not a customs checkpoint with a shared database and verified information about any potential user,” they said.
In another post, the vendor describes software that allows the creation of fake selfies, including video. “We do live selfies. 3D biometric is possible for us. take photos with id cards. print any docs. we can be anyone you need,” the same vendor advertised on the paid forum Ver.sc.
CoinDesk reviewed a sample of accounts at exchanges Binance US, Coinbase Pro and Kraken and payment services Cash App and Wirex that were available for purchase on the black market. The accounts had been put up for sale by several different vendors. The prices of these accounts ranged from $170 to $250, all paid in bitcoin.
Along with login credentials, these accounts came with private data of the purported account owners, all of whom appeared to be genuine U.S. or European Union residents. The data included dates of birth, street addresses and, in the case of the U.S. residents, Social Security numbers.
After reviewing the accounts, CoinDesk contacted the crypto exchanges and payment services to check their authenticity. None of the companies would say whether the accounts were genuine, explaining they can’t comment on individual accounts.
CoinDesk searched online databases such as Spokeo, SearchPeopleFree and ClustrMaps and found four people whose names, years of birth and cities matched those on the black-market accounts. Two of those people had matching street addresses as well.
Attempts to contact these and other individuals whose names were on the reviewed accounts by phone, email and social media were unsuccessful, and CoinDesk has mailed them letters to alert them their data is potentially being abused.
Some people are traders, people can not completely remain anonymous due to one reason or the other best known to individuals. But people should not think that centralized exchanges can not be used for criminal activities. People need to think if it is necessary to give out their personal information to centralized services, it is not worth it if not necessary. The most important of all is to know how to avoid bad actors, do not think centralized services give any protection than a way to reveal your information to other bad actors during kyc breach that can lead to phishing attempts and malware attacks.
This is not about account sales, it is about the cons of kyc, expect scam if trying to buy a centralized exchange account, or blocking/freezing of account. It is not your key, it is not your coin, avoid account buying to avoid scam.
