Some of these have now patched up the holes and removed the Coinhive software, though hundreds still have yet to do so. The flaw that allowed the hackers to take advantage of this has been known about since March and Drupal has been updated by the developers since.

However, not all websites have installed the necessary patches, which has left many vulnerable. Although plus sites were infected in this latest attack, with more than a million sites using the CMS globally, there is real potential for further attacks of increased scope. If you have cheap electricity and enough investment funds though, it is possible.

Editors' Recommendations. Among victims, there are many government and university portals, such as the National Labor Relations Board US federal agency , the Turkish Revenue Administration, the University of Aleppo, and others, which Mursch has recorded in a Google Docs spreadsheet. But the biggest name on the list is surely Chinese hardware maker Lenovo, which Mursch added in an update following the initial publishing of his research.

The Imperva team didn't share the number of sites affected by this campaign but said crooks didn't limit themselves to dropping an in-browser miner only. They also installed a PHP-based backdoor on all compromised servers —for future access, even if the server owner updated his site— and a classic coinminer that utilized the underlying server's resources to mine Monero, instead of the users' browsers.

Imperva says the Monero address used in the Kitty campaign had also been spotted at the start of April in another series of hacks that targeted servers running vBulletin 4. While campaigns are still raging, it is important to remember that updating a hacked site is not enough. Site owners should also scan for backdoors and consider restoring from an older backup or reinstalling the site from scratch.

Cryptocurrency mining malware, meanwhile, refers to any code that uses an infected system's CPUs to "mine" for cryptocurrency by solving computational challenges that build the virtual currency's blockchain in return for a potential reward see: Malware Moves: Attackers Retool for Cryptocurrency Theft.

Critical Security Fixes On Feb. These "critical releases" update Drupal 8. The Drupal project team recommends that all users immediately apply the updates. A proof-of-concept exploit for the flaw was first published on Thursday. Researchers say the flaw is easy to exploit.

May 8, Share Malware miners managed to infect more than big websites recently, resulting in the generation of large quantities of cryptocurrency for the attackers. The cryptojackers appear to have taken advantage of a flaw in content management system CMS Drupal to install the stealthy mining software under the nose of website owners. It even replaced ransomware as one of the top go-to methods for making money with malware.

Although not as impactful to affected victims as ransomware or identity theft, it can still cause slowdowns on a system and potentially damage hardware if allowed to run rampant. It saw the hackers infiltrate websites that were running outdated and vulnerable versions of the Drupal CMS to install the cryptomining software Coinhive, as per PCMag.

Although designed to allow website owners to monetize their users in ways other than advertising, Coinhive has been used by hackers to take advantage of vulnerable websites and their unwitting users.
