A malware botnet known as 'Ebury' has infected almost 400,000 Linux servers since 2009, with roughly 100,000 still compromised as of late 2023.

ESET researchers have been following the financially motivated malware operation for over a decade now, warning about significant updates in the payload's capabilities in 2014 and again in 2017.
