Exploring the PHP2Shell Exploit Attempts: A Delve into the World of Mirai Malware and Address Space Layout Randomization
The PHP2Shell vulnerability in PHP versions 5.4 to 8.5 allows for unauthenticated remote code execution via specially crafted HTTP requests. The vulnerability has been exploited by attackers to deploy Mirai malware, a type of DDoS botnet. The attackers have been attempting to exploit CVE-2026-109618 and CVE-2026-109619 vulnerabilities, which have a CVSS score of 9.2. The Mirai malware is designed to issue a DNS query and establish a C2 channel on TCP port 50792. The attacks have been observed to originate from specific IP addresses, including 85.11.167[.]243, 217.60.242[.]76, and 45.198.224[.]169. The lack of a successful attack leveraging PHP2Shell in the wild suggests that threat actors are "struggling" to come up with reliable exploits. The consequences of successful exploitation are severe, as it permits an attacker to execute code with the permissions of the web application. The PHP2Shell vulnerability has been found on over 3.08 million hosts and 56.6 million web properties running PHP.
PHP2Shell, a vulnerability in PHP versions 5.4 to 8.5, has been a major target for attackers in recent times. The vulnerability, which can result in unauthenticated remote code execution (RCE) via specially crafted HTTP requests, has been exploited by attackers to deploy Mirai malware, a type of DDoS botnet. This article will delve into the world of PHP2Shell, Mirai malware, and address space layout randomization (ASLR), exploring the context data provided and the implications of these technologies.
The PHP2Shell vulnerability was publicly disclosed in October 2026, and since then, attackers have been attempting to exploit it to deploy Mirai malware. The attacks have been observed to originate from specific IP addresses, including 85.11.167[.]243, 217.60.242[.]76, and 45.198.224[.]169. These IP addresses have been found to contact 92.118.112[.]100 to retrieve a loader, which is responsible for deploying the Mirai botnet variant.
The attackers have been attempting to exploit the CVE-2026-109618 and CVE-2026-109619 vulnerabilities, which have a CVSS score of 9.2. These vulnerabilities can result in unauthenticated RCE via specially crafted HTTP requests. The attackers have been using a PHP2Shell exploit tooling for PHP 8.4.26 on an exposed attacker-controlled server, which is expected to be a key component of their attack strategy.
The Mirai malware, also known as Potassium, has been designed to issue a DNS query for thunder.godofthunder[.]st, resolves it to 134.199.154[.]64, and establishes a C2 channel on TCP port 50792. The malware is designed to launch sustained volumetric flood attacks against two adjacent hosts located within a single Ukrainian network.
The attacks have been observed to originate from a China-based IP address that has been trying to drop a web shell via a server-side session file. The web infrastructure company Cloudflare has observed tens of thousands of attempts to exploit the flaw 45 minutes after the flaws were publicly announced, before climbing to hundreds of thousands within 2 hours and millions as of early October 22, 2026.
The lack of a successful attack leveraging PHP2Shell in the wild suggests that threat actors are "struggling" to come up with reliable exploits. The developers of the PHP2Shell exploit have developed a novel technique that chains the two vulnerabilities together, using a memory leak to bypass ASLR and achieve remote code execution on x86-64 systems, even with PHP's recommended production error-display setting.
The consequences of successful exploitation of the flaws are severe, as it permits an attacker to execute code with the permissions of the web application, potentially gaining access to API keys, database connections, and other internal services the application can reach. An attacker does not necessarily need administrator or root access to cause significant damage.
The implications of this attack are significant, as the PHP2Shell vulnerability has been found on over 3.08 million hosts and 56.6 million web properties running PHP. Many applications with web servers and similar will likely remain vulnerable until their respective vendors patch these items.
In conclusion, the PHP2Shell exploit attempts are a serious concern for the cybersecurity community. The Mirai malware, designed to launch sustained volumetric flood attacks, is a significant threat to the global network infrastructure. The lack of a successful attack leveraging PHP2Shell in the wild suggests that threat actors are struggling to come up with reliable exploits. The developers of the PHP2Shell exploit have developed a novel technique that chains the two vulnerabilities together, using a memory leak to bypass ASLR and achieve remote code execution on x86-64 systems.
