researchers from Germany, Switzerland, the UK and Spain have all reported some unwanted behavior.
The process of "mining" is done by individuals or groups compete to solve some advanced mathematical puzzle, in return cryptocurrency is awarded.
The process is difficult ,so it requires the powerful hardware.more the power more likely the miner to receive a cryptocurrency.which makes supercomputers a main target for hacking attempts.The University of Edinburgh, which runs the ARCHER supercomputer, was the first to experience the public of the breach.five supercomputing clusters in Germany were forced offline for the same reason.further operators across Germany and Switzerland revealed their fleets of supercomputers had also suffered the same.it is thought it all began with compromised SSH credentials, stolen from universities in Canada, China, and Poland.
the organization that coordinates research projects across supercomputers in the state of Baden-Württemberg, Germany,told that five of its high-performance computing clusters had to be shut down due to similar security incidents.
This continued on Wednesday when security researcher Felix von Leitner told in a blog that a supercomputer housed in Barcelona, Spain, was also impacted by a security issue and had been shut down as a result.
The malware samples were tested at cado security,which is a UK-based cyber security firm. The company claimed that the attackers able to have gained access to the supercomputer clusters via compromised SSH credentials.
The Swiss Center of Scientific Computations (CSCS) in Zurich, Switzerland also shut down external access to its super computer.
