Coinciding with the rising interest in stealing cryptocurrencies, distributed ledger technology (DLT), the technology that underpins cryptocurrencies, has also provided cyber criminals with a unique means of hosting their malicious content.

Traditional methods include using bulletproof hosting, fast-flux, Tor infrastructure, and/or domain generation algorithms (DGAs) to help obfuscate the malicious infrastructure. While we expect cyber criminals to continue to use these techniques for the foreseeable future, another trend is emerging: the use of blockchain infrastructure.
