Mocha Manakin, a threat actor named by Red Canary, is employing a sophisticated "paste-and-run" technique to compromise systems. This method involves tricking users into executing malicious scripts via PowerShell, leading to the deployment of a custom NodeJS backdoor known as NodeInitRAT. Red Canary's report highlights that this backdoor could potentially lead to ransomware attacks. SocPrime has also released information regarding the detection of Mocha Manakin attacks, emphasizing the backdoor's capabilities.
Red Canary notes the adversary leverages ClickFix technique to deliver NodeJS-based backdoor named NodeInitRAT. Hunting for suspicious events related to PowerShell spawning node.exe can be an effective detection method. Security analysts can monitor process creation events where powershell.exe is the parent process and node.exe is the child process to identify potentially malicious activity associated with the NodeInitRAT backdoor. Soc Prime offers Sigma rules to detect Mocha Manakin paste-and-run attacks spreading the NodeInitRAT backdoor. It's crucial to detect this threat as early as possible, as researchers note overlaps with Interlock ransomware. These rules can aid in identifying suspicious behavior and mitigating the risk of further compromise, including data exfiltration and ransomware deployment. Recommended read:

Sophos has revealed a significant malware campaign operating on GitHub, targeting a diverse audience, including hackers, gamers, and cybersecurity researchers. The threat actor, identified by the alias "ischhfd83," has cleverly disguised malicious code within seemingly legitimate repositories, some appearing as malware development tools and others as gaming cheats. This deceptive approach aimed to infect users with infostealers and Remote Access Trojans (RATs) like AsyncRAT and Remcos. Upon investigation, Sophos uncovered a network of 133 backdoored repositories linked to the same threat actor, indicating a widespread and coordinated effort to compromise unsuspecting individuals.
The campaign employed sophisticated techniques to enhance its credibility and evade detection. The threat actor used multiple accounts and contributors, alongside automated commits to mimic active development. Victims who compiled the code in these repositories inadvertently triggered a multi-stage infection chain. This chain involved VBS scripts, PowerShell downloads, and obfuscated Electron apps, all designed to stealthily deploy malicious payloads. By masquerading as valuable resources, such as hacking tools or game enhancements, the threat actor successfully lured users into downloading and executing the backdoored code, showcasing the campaign's deceptive effectiveness. Sophos reported the malicious repositories to GitHub, leading to the takedown of most affected pages and related malicious pastes. However, the incident highlights the importance of vigilance when downloading and running code from unverified sources. Cybersecurity experts recommend users carefully inspect code for obfuscated strings, unusual domain calls, and suspicious behavior before execution. Employing online scanners and analysis tools, as well as running untested code in isolated environments, can further mitigate the risk of infection. The discovery also underscores the growing trend of cybercriminals targeting each other, further complicating the threat landscape. Recommended read:

A new botnet campaign, dubbed AyySSHush, is targeting ASUS routers, compromising over 9,000 devices globally. The attackers are exploiting a known command injection vulnerability, CVE-2023-39780, along with other authentication bypass techniques to gain unauthorized access. Models such as RT-AC3100, RT-AC3200, and RT-AX55 are among those being targeted, with attackers seeking to establish a persistent presence within the compromised routers. GreyNoise researchers, who uncovered the campaign, emphasize the stealthy tactics employed, which include disabling router logging and avoiding the installation of malware, making detection difficult.
Attackers initially gain access to ASUS routers through brute-force login attempts and the exploitation of authentication bypass flaws, including techniques that have not yet been assigned CVEs. Once inside, they leverage the CVE-2023-39780 command injection vulnerability to execute system commands and modify router settings. These commands enable SSH access on a custom port, typically TCP/53282, and insert an attacker-controlled public key for remote access. This allows the attackers to maintain a persistent backdoor into the compromised routers, even after firmware upgrades and reboots. As a result of this sophisticated campaign, compromised ASUS routers require a factory reset to fully remove the persistent SSH backdoor. Standard firmware updates are insufficient, as the attackers abuse legitimate router configuration features stored in non-volatile memory (NVRAM). GreyNoise recommends users rotate all authentication tokens, including passwords and SSH keys, and perform a factory reset to clear the affected devices' NVRAM. Users can also use runZero's service inventory to locate potentially impacted assets by querying for SSH protocol on port 53282, or scan for the attacker’s public key using the SSHamble tool.

Attackers are actively exploiting vulnerabilities in popular content management systems (CMS) like WordPress and Craft CMS to gain unauthorized access to web servers. These attacks highlight the critical need for website administrators to stay vigilant and promptly apply security patches. A significant phishing campaign has been identified targeting WordPress WooCommerce users, where victims are tricked into downloading a fake security patch that actually installs a backdoor on their sites, allowing attackers persistent access.
Craft CMS is also facing active exploitation of a critical vulnerability, CVE-2025-32432, which allows for Remote Code Execution (RCE). This flaw is particularly dangerous as it is being chained with another vulnerability, CVE-2024-58136 in the Yii framework, to facilitate zero-day attacks. These chained exploits enable attackers to breach servers and steal sensitive data. Researchers are urging Craft CMS users to update to patched versions immediately to mitigate the risk. An investigation into a compromised server revealed that attackers used CVE-2025-32432 to download a PHP-based file manager, which then enabled them to upload further malicious PHP files. The investigation involved analyzing access logs from the web server and Craft CMS logs, including web logs and phperrors.log, to identify the attacker's actions. The attack leverages Craft CMS's asset management system, exploiting a flaw in how the system handles asset IDs and image transformations. Recommended read:

A new malware campaign is targeting WordPress websites by using a plugin disguised as a security tool. The malicious plugin, often named 'WP-antymalwary-bot.php', provides attackers with administrator access to compromised sites, all while remaining hidden from the WordPress admin dashboard. The Wordfence Threat Intelligence team discovered this threat in late January 2025 during a site cleanup, revealing the plugin's ability to maintain access, execute remote code, and inject malicious JavaScript. Other names associated with the plugin include addons.php, wpconsole.php, and wp-performance-booster.php, underscoring the campaign's wide reach and adaptability.
The disguised plugin is designed to appear legitimate, mimicking genuine plugin structure and code indentation, which allows it to easily evade detection by site administrators. Once installed, the plugin exploits the REST API to facilitate remote code execution, injecting malicious PHP code into the site theme's header file or clearing caches of popular caching plugins. Furthermore, the plugin incorporates a "pinging" function to report back to a command-and-control server and the ability to spread malware into other directories. A particularly concerning feature is a modified wp-cron.php file that can reactivate the plugin if removed, ensuring the malware's persistence on the compromised site. Security researchers have observed newer versions of this malware handling code injections differently. These updated versions fetch JavaScript code from compromised domains to serve ads or spam, demonstrating the malware's evolving sophistication. The presence of Russian language comments within the code suggests that the threat actors may be Russian-speaking. The discovery of this malware campaign highlights the importance of vigilance when installing WordPress plugins. Site owners should always verify the legitimacy and reputation of plugins before installation to prevent compromise and maintain the integrity of their websites. Recommended read:

A large-scale phishing campaign is actively targeting WordPress WooCommerce users, employing deceptive tactics to compromise their websites. Cybercriminals are sending out fake security alerts, urging recipients to download a "critical patch." Unsuspecting users who fall for the scam and download the so-called patch are actually installing a malicious plugin that creates a hidden administrator account and gives attackers backdoor access to their WordPress sites. This campaign highlights the evolving sophistication of cyber threats against e-commerce platforms.
The phishing emails are designed to mimic official WooCommerce communications and often warn of a non-existent "Unauthenticated Administrative Access" vulnerability. To further deceive users, the attackers employ homograph attacks, using domain names that closely resemble the legitimate WooCommerce website but contain subtle character differences such as 'woocommėrce[.]com'. The fake patch, once installed, allows attackers to inject malicious code, redirect site visitors, or even encrypt server resources for extortion. Cybersecurity researchers advise WooCommerce users to be extremely cautious when receiving security alerts and to verify the authenticity of any patches directly through official WooCommerce channels. Users should also scan their instances for suspicious plugins or administrator accounts and ensure all software is up to date. The ultimate goal of the attackers is to gain remote control over the websites, allowing them to inject spam or sketchy ads, redirect site visitors to fraudulent sites, enlist the breached server into a botnet for carrying out DDoS attacks, and even encrypt the server resources as part of an extortion scheme.
