The recent emergence of PG_MEM, a sophisticated malware strain specifically designed to exploit PostgreSQL databases for cryptocurrency mining, proved that the criminals’ modifying strategies are continuously in progress. This is a very dangerous threat to organizations that use PostgreSQL for their major activities, as it is almost invisible.
PostgreSQL database fell victim to a brute force attack, where the attacker managed to guess the password and gain access. Exploiting a feature that allows command execution, the intruder created a superuser role within the database. They then deposited two files onto the system. These files are designed to avoid detection, maintain control, and ultimately set up cryptocurrency mining operations. The attacker now also has the ability to run commands, view data, and control the server.
PG_MEM utilizes PostgreSQL’s processing power and hardware, delivering its payloads to hide operations and mining cryptocurrencies. Through penetration of these databases, the malware forms malignant procedures that run mining algorithms, take up CPU and memory resources, and can hinder the normal operation of other applications.
The implications of PG_MEM infections are many-fold. The high-intensity mining operations that are carried out can cause database deterioration, resulting in slow responses and interference with vital activities. Furthermore, having the malware present within the system also increases the risk of other attacks on the database, like data theft or ransomware attacks.
The way to protect against being a victim of PG_MEM is to follow thorough security measures, which include– Regular patching, Strong access controls, Network segmentation, Regular monitoring, and Security solutions.
Through these measures, one can discharge the probable risk issues that arise with the efforts of PG_MEM and other malware that targets databases to harm the valuable data that organizations have and affect the functioning of their key systems.
