Researchers have traced the origins of a campaign – infecting SQL servers to mine cryptocurrency – back to an Iranian software firm.
Researchers have made new discoveries surrounding the source of a previously-uncovered cryptomining operation that has targeted internet-facing database servers.
The campaign, dubbed MrbMiner, was discovered in September 2020 downloading and installing a cryptominer on thousands of SQL servers. Now, researchers with Sophos have tracked the origin of the campaign to what they claim is a small software development company based in Iran.
“The name of an Iran-based software company was hardcoded into the miner’s main configuration file,” said researchers with Sophos in a Thursday analysis. “This domain is connected to many other zip files also containing copies of the miner. These zip files have in turn been downloaded from other domains, one of which is mrbftp.xyz.”
