The solution integrated with BTCV is designed to mend loopholes in the irreversible nature of transactions in blockchain using an innovative three-key proprietary wallet. Powered by three private keys, this security solution gives users time to react to a potential theft. It also provides them with the authority to cancel any unauthorized transaction and the tools needed to do so.
The solution is comprised of three keys -- a standard transaction key, a cancel transaction key and a fast transaction key. A major innovation that the solution offers is the cancel transaction key, which gives users approximately 24 hours to cancel a suspicious or erroneous payment. The time allowed is based on the time needed to calculate blocks to confirm the transaction on the blockchain.
The fast transaction key enables users to complete a transaction before a block is generated, which can be a useful tool when making a transfer to trusted contacts. The standard transaction key works in the background to ensure a smooth operation of all transactions. Janczewski sees a lot of action these days. Once Lazarus has successfully hacked a target and taken control of the money, the group attempts to cover up its trail to throw off investigators.
These tactics typically involve moving coins to different wallets and currencies—for example, switching from ether to Bitcoin. But the North Korean playbook has evolved in the last few years. The idea is to make the trail go cold or, better yet, raise false alarms for investigators.
The Lazarus laundering operation, says Janczewski, involves creating and maintaining hundreds of false accounts and identities, a consistent level of sophistication and effort that underlines just how important the operation is for Pyongyang. Stealing cryptocurrency is far from the perfect crime, however. Police and regulators were once almost clueless, but they now have years of cryptocurrency investigation experience under their belts.
