There are a lot of reports regarding various vulnerabilities, ransomwares and malwares which are used by hackers to somehow acquire and mine cryptocurrency. Imperva Incapsula has been inspecting the attacks, and reportedly came across the “Kitty” malware, which is an advanced Monero cryptocurrency miner, utilizing a “webminerpool”, an open source mining software for browsers.

According to the information published on Imperva Incapsula, when the Kitty bash script is executed, a PHP file named “kdrupal.php” is written to the infected server disc.

The attacker reinforces their foothold in the infected server and guarantees dominance using a backdoor independent of the Drupal vulnerability. Next, the script registers a time-based job scheduler (“cronjob”) which periodically re-downloads and executes a bash script from a remote host, every minute, giving the attacker the ability to re-infect the server or quickly change or push updates to the infected servers under their control.
