E-commerce sites using Adobe’s Magento 2 computer software are the focus on of an ongoing campaign that has been lively because at minimum January 2023.
The attacks, dubbed Xurum by Akamai, leverage a now-patched critical security flaw (CVE-2022-24086, CVSS score: 9.8) in Adobe Commerce and Magento Open up Source that, if successfully exploited, could lead to arbitrary code execution.
“The attacker appears to be to be intrigued in payment stats from the orders in the victim’s Magento retail outlet placed in the earlier 10 times,” Akamai scientists reported in an examination revealed last week, attributing the marketing campaign to actors of Russian origin.
In the attack chains noticed by the company, CVE-2022-24086 is weaponized for first accessibility, subsequently exploiting the foothold to execute malicious PHP code that gathers information and facts about the host and drops a web shell named wso-ng that masquerades as a Google Browsing Advertisements component.
Not only is the web shell backdoor run in memory, it also activated only when the attacker sends the cookie “magemojo000” in the HTTP request, following which facts about the profits buy payment approaches in the previous 10 days is accessed and exfiltrated.
The attacks culminate with the development of a rogue admin person with the name “mageworx” (or “mageplaza”) in what seems to be a deliberate try to camouflage their steps as benign, for the two monikers refer to common Magento 2 extension shops.
wso-ng is stated to be an evolution of the WSO web shell, incorporating a new concealed login webpage to steal qualifications entered by victims. It even more integrates with legit equipment like VirusTotal and SecurityTrails to glean the contaminated machine’s IP reputation and get aspects about other domains hosted on the similar server.
On the internet buying web-sites have been focused for many years by a class of attacks known as Magecart in which skimmer code is inserted into checkout internet pages with the goal of harvesting payment knowledge entered by victims.
“The attackers have demonstrated a meticulous solution, targeting precise Magento 2 occasions rather than indiscriminately spraying their exploits across the internet,” the researchers reported.
“They reveal a higher stage of experience in Magento and commit sizeable time in being familiar with its internals, location up attack infrastructure, and testing their exploits on real targets.”
