By taking advantage of cryptomining, threat actors can attack multiple devices at once and compromise a provider organizations computing power. In the world of healthcare security, there are always new threats to replace the old, keeping IS professionals on their toes and creating the need for improved controls and mitigation strategies to keep both organizations and patients safe. Over the past couple of years, security leaders have spent a lot of time and energy combating the rise of ransomware. Now, that threat is in decline and a new threat is emerging: cryptojacking.Cryptocurrencies like bitcoin, Monero and others rely on blockchain technology to keep an immutable ledger of all of the transactions that take place, which is an attractive and necessary feature of these digital currencies. The blocks in the ledgers are encrypted, and the necessary mathematical computations require a lot of processing power. Some of these digital currencies will pay for the processing required to build and verify the blockchain, a process called cryptomining.For willing participants, cryptomining is a way to make money, but because it takes a lot of processing power and because the cryptocurrency may only pay small amounts for each block of work completed the ability to do this computation at scale is important.With cryptojacking, threat actors place cryptomining software on as many computing devices as possible in order to maximize profit. The attackers employ many of the same techniques used to distribute ransomware. If someone has infected 100,000 devices, and each device can generate 25 cents per day, thats not a bad return for a day of doing nothing.
