​Analysis of new CosmicStrand rootkit

Researchers with SecureList have discovered a new advanced rootkit for UEFI firmware for Windows that has received the name CosmicStrand. This type of malware is highly evasive and persistent, as it remains on the victim's system even after several reboots. As per the infection chain, CosmicStrand attacks on kernel level, aiming at firmware images from Gigabyte or ASUS' motherboards. These firmware images are modified in the CSMCORE DXE controller to execute a code chain during system boot that downloads the payload hosted on Windows. According to researchers, the modifications on the firmware images could be achieved by exploiting a vulnerability. This would imply that the attackers had previous access to the victim's computer to extract, modify and overwrite the motherboard's firmware. The countries where this operation is taking place so far are China, Vietnam and Iran. Plus, the victims are normally users with free versions of the products impacted.


0-day vulnerability in PrestaShop exploited against e-commerce stores

The exploitation of a 0-day vulnerability has been detected in PrestaShop, the most popular open source e-commerce platform in Europe and Latin America, used by around 300,000 customers worldwide. PrestaShop reported that the attackers were exploiting a combination of vulnerabilities to inject malicious code into websites using its software, allowing them to execute arbitrary code with the purpose of stealing e-commerce customers payment information. Among the exploited flaws, the PrestaShop team detected a SQL injection 0-day (CVE-2022-36408 [1]) that has been fixed in the version, however, they state that there may be more methods to carry out this attack. In addition, PrestaShop has published a series of tests to verify the attack, as well as recommendations to keep the e-commerce site secure such as keeping the software updated and disabling the MySQL Smarty Cache function, used by the attackers to carry out the attacks.
