HP servers are used to mine unknown cryptocurrency

Using a flaw in Log4j, HP servers, which use AMD CPUs, were hacked and used to mine the Raptoreum (RTM) cryptocurrency. Although it is a small currency, with a market capitalization of R$145 million, the attack surprised by doubling its mining power.

This failure of Log4j has been widely warned, with recommendations to update it to a fixed version or to take other actions in cases where an upgrade is not possible.

Despite this, hackers took advantage of this flaw to mine Raptoreum (RTM) for about 8 consecutive days this month. Another point to be considered is the security of these coins with low computational power.

Hackers mined BRL 625,000 using HP servers

Hewlett-Packard 9000 EPYC servers, known to use AMD processors, were hacked due to a flaw in the Log4j library and used to mine the Raptoreum (RTM) cryptocurrency between December 9th and 17th.

While the choice of currency seems random, there is actually a good reason for it. Raptoreum is mined only by processors (CPUs), unlike Ethereum (ETH) whose use of graphics cards (GPUs) is dominant, as is Bitcoin (BTC) with ASICs.

In this way, hackers doubled the computational power of mining this small coin, causing it to jump from 200 MH/s to 400 MH/s during the eight days they used HP servers to do so.

“Out of nowhere the hash rate of Raptoreum’s total network has increased in recent weeks, from 200 MH/s to 400 MH/s with a single address contributing 100-200 MH/s […] Few organizations in the world have their hands on this type of hardware, making it extremely unlikely that the attack was carried out using the hardware itself. Through a private investigation, there is strong evidence to suggest that Hewlett-Packard 9000 EPYC servers were being used for mining. We found that the miners were using HP nicknames and were abruptly stopped, which adds to speculations of a company breach.”

The above testimonial was made by a Raptoreum developer to the website ONE, which covered the matter. In addition, he also commented that hackers managed to get $110,000 (BRL 625,000) by mining 3.4 million RTM.

Hack is also harmful to cryptocurrency

In addition to the problems caused to the owners of hacked equipment such as these servers, this hack can also have a serious impact on a small cryptocurrency like the Raptoreum.

First, as the hacker has no hardware and energy costs, he can perform 51% attacks on low hashrate coins. While this is not the case for cryptocurrencies like Bitcoin and Ethereum, this raises concerns for smaller projects.

Going further, this lucky mined can also be dumped on the market, causing the coin to instantly lose its value. Another coin that is heavily mined in similar attacks is the Monero (XMR), although it appears to be too big to have these same problems.
