Hackers made $110,000 in crypto on hijacked HP servers

Hackers earned $110,000 by gaining access to HP servers. Between December 9 and 17, the servers were most likely under the control of hackers, who would have made $110,000 by mining cryptocurrency.

Anonymous attackers used a vulnerability in the Log4J library to hack HP 9000 servers with AMD EPYC processors to mine the Raptoreum CPU cryptocurrency on these resources between December 9 and December 17. As a result, the Raptoreum network’s hash rate doubled until the device was taken offline.

Because it allows attackers to make connections, download data, and run arbitrary code on a controlled system without having physical access, the Log4J vulnerability is ranked the highest. Raptoreum is based on the GhostRider algorithm, which was designed for central processors and is resistant to ASIC systems. For this reason, HP 9000 servers with AMD EPYC processors were chosen as targets.

It was most likely one of the numerous victims of the Log4J flaw, which affected Amazon, IBM, and Microsoft. The impacted HP servers, on the other hand, were discovered to be powered by AMD’s 9000 EPYC CPU, which can mine Raptoreum at a rate of 400 MH/s.

On December 9th, Raptoreum engineers noticed an unusual hash rate rise on the network. The network’s number of machines grew rapidly, and productivity increased from 200 MH / s to 400 MH / s. The address that the HP servers belonged to received roughly 30% of the total block reward, or 3.4 million RTM, during the time they were mining.

Raptoreum’s core algorithm, GhostRider, is a mix of proof-of-work and proof-of-stake that is immune to accelerators and other kinds of instabilities. GhostRider favors AMD processors because of their large L3 cache. Raptoreum is surprisingly profitable on AMD’s pricey Epyc server CPUs, thanks to the 256 MB of cache on models with 32 or more cores. 

In exploratory research conducted by Raptoreum’s engineers, the hackers were determined to be targeting HP servers, which were discovered to be 9000-series and using Epyc CPUs. All of this information is available on the Raptoreum blockchain. Raptoreum’s founders are bringing it up to refute the myth that it is insecure.
