Cyber Security researchers at Guardicore Labs today published a detailed report on a widespread cryptojacking campaign attacking Windows MS-SQL and PHPMyAdmin servers worldwide. Dubbed Nansh0u , the malicious campaign is reportedly being carried out by an APT-style Chinese hacking group who has already infected nearly 50,000 servers and are installing a sophisticated kernel-mode rootkit on compromised systems to prevent the malware from being terminated. The campaign, which dates back to February 26 but was first detected in early-April, has been found delivering 20 different payload versions hosted on various hosting providers. The attack relies on the brute-forcing technique after finding publicly accessible Windows MS-SQL and PHPMyAdmin servers using a simple port scanner. Upon successful login authentication with administrative privileges, attackers execute a sequence of MS-SQL commands on the compromised system to download malicious payload from a remote file server and...

A critical security vulnerability has been reported in phpMyAdmin—one of the most popular applications for managing the MySQL database—which could allow remote attackers to perform dangerous database operations just by tricking administrators into clicking a link. Discovered by an Indian security researcher, Ashutosh Barot , the vulnerability is a cross-site request forgery (CSRF) attack and affects phpMyAdmin versions 4.7.x ( prior to 4.7.7 ). Cross-site request forgery vulnerability, also known as XSRF, is an attack wherein an attacker tricks an authenticated user into executing an unwanted action. According to an advisory released by phpMyAdmin, " by deceiving a user to click on a crafted URL, it is possible to perform harmful database operations such as deleting records, dropping/truncating tables, etc. " phpMyAdmin is a free and open source administration tool for MySQL and MariaDB and is widely used to manage the database for websites created with WordPress,...

Cybersecurity isn't just another checkbox on your business agenda. It's a fundamental pillar of survival. As organizations increasingly migrate their operations to the cloud, understanding how to protect your digital assets becomes crucial. The shared responsibility model , exemplified through Microsoft 365's approach, offers a framework for comprehending and implementing effective cybersecurity measures.  The Essence of Shared Responsibility  Think of cloud security like a well-maintained building: the property manager handles structural integrity and common areas, while tenants secure their individual units. Similarly, the shared responsibility model creates a clear division of security duties between cloud providers and their users. This partnership approach ensures comprehensive protection through clearly defined roles and responsibilities.  What Your Cloud Provider Handles  Microsoft maintains comprehensive responsibility for securing the foundational eleme...

Over a month ago we reported about two critical zero-day vulnerabilities in the world's 2nd most popular database management software MySQL: MySQL Remote Root Code Execution (CVE-2016-6662) Privilege Escalation (CVE-2016-6663) At that time, Polish security researcher Dawid Golunski of Legal Hackers who discovered these vulnerabilities published technical details and proof-of-concept exploit code for the first bug only and promised to release details of the second bug (CVE-2016-6663) later. On Tuesday, Golunski has released proof-of-concept (POC) exploits for two vulnerabilities: One is the previously promised critical privilege escalation vulnerability ( CVE-2016-6663 ), and another is a new root privilege escalation bug ( CVE-2016-6664 ) that could allow an attacker to take full control over the database. Both the vulnerabilities affect MySQL version 5.5.51 and earlier, MySQL version 5.6.32 and earlier, and MySQL version 5.7.14 and earlier, as well as MySQL forks...
