Rogue WordPress Plugin Exposes E-Commerce Sites to Credit Card Theft
Dec 22, 2023 Skimming / Web Security
Threat hunters have discovered a rogue WordPress plugin that's capable of creating bogus administrator users and injecting malicious JavaScript code to steal credit card information. The skimming activity is part of a  Magecart campaign  targeting e-commerce websites, according to Sucuri. "As with many other malicious or fake WordPress plugins it contains some deceptive information at the top of the file to give it a veneer of legitimacy," security researcher Ben Martin  said . "In this case, comments claim the code to be 'WordPress Cache Addons.'" Malicious plugins typically find their way to WordPress sites via either a  compromised admin user  or the  exploitation of security flaws  in another plugin already installed on the site. Post installation, the plugin replicates itself to the  mu-plugins  (or must-use plugins) directory so that it's automatically enabled and conceals its presence from the admin panel. "Since the only way to re

May 10, 2024Endpoint Security / Threat Detection
A guide to finding the right endpoint detection and response (EDR) solution for your business' unique needs. Cybersecurity has become an ongoing battle between hackers and small- and mid-sized businesses. Though perimeter security measures like antivirus and firewalls have traditionally served as the frontlines of defense, the battleground has shifted to endpoints. This is why endpoint detection and response (EDR) solutions now serve as critical weapons in the fight, empowering you and your organization to detect known and unknown threats, respond to them quickly, and extend the cybersecurity fight across all phases of an attack.  With the growing need to defend your devices from today's cyber threats, however, choosing the right EDR solution can be a daunting task. There are so many options and features to choose from, and not all EDR solutions are made with everyday businesses and IT teams in mind. So how do you pick the best solution for your needs?
