Program scanning for vulnerabilities in phpMyAdmin web servers.
ZmEu is a computer vulnerability scanner which searches for web servers that are open to attack through the phpMyAdmin program,[1][2][3] It also attempts to guess SSH passwords through brute-force methods,[4] and leaves a persistent backdoor. It was developed in Romania and was especially common in 2012.
It is apparently named after Zmeu, a dragon-like being in Romanian folklore.[5]
