Cybersecurity researchers have discovered a new botnet malware family called Gorilla (aka GorillaBot) that draws its inspiration from the leaked Mirai botnet source code. Cybersecurity firm NSFOCUS, which identified the activity last month, said the botnet "issued over 300,000 attack commands, with a shocking attack density" between September 4 and September 27, 2024. No less than 20,000 commands designed to mount distributed denial-of-service (DDoS) attacks have been issued from the botnet every day on average. The botnet is said to have targeted more than 100 countries, attacking universities, government websites, telecoms, banks, gaming, and gambling sectors. China, the U.S., Canada, and Germany have emerged as the most attacked countries. The Beijing-headquartered company said Gorilla primarily uses UDP flood , ACK BYPASS flood, Valve Source Engine (VSE) flood , SYN flood , and ACK flood to conduct the DDoS attacks, adding the connectionless nature of the UDP prot...

Cybersecurity researchers have identified a new attack that exploits misconfigurations in Apache Hadoop and Flink to deploy cryptocurrency miners within targeted environments. "This attack is particularly intriguing due to the attacker's use of packers and rootkits to conceal the malware," Aqua security researchers Nitzan Yaakov and Assaf Morag  said  in an analysis published earlier this week. "The malware deletes contents of specific directories and modifies system configurations to evade detection." The infection chain targeting Hadoop leverages a misconfiguration in the YARN's (Yet Another Resource Negotiator)  ResourceManager , which is responsible for tracking resources in a cluster and scheduling applications. Specifically, the misconfiguration can be exploited by an unauthenticated, remote threat actor to execute arbitrary code by means of a crafted HTTP request, subject to the privileges of the user on the node where the code is executed. The ...

Vulnerability Management (VM) has long been a cornerstone of organizational cybersecurity. Nearly as old as the discipline of cybersecurity itself, it aims to help organizations identify and address potential security issues before they become serious problems. Yet, in recent years, the limitations of this approach have become increasingly evident.  At its core, Vulnerability Management processes remain essential for identifying and addressing weaknesses. But as time marches on and attack avenues evolve, this approach is beginning to show its age. In a recent report, How to Grow Vulnerability Management into Exposure Management (Gartner, How to Grow Vulnerability Management Into Exposure Management, 8 November 2024, Mitchell Schneider Et Al.), we believe Gartner® addresses this point precisely and demonstrates how organizations can – and must – shift from a vulnerability-centric strategy to a broader Exposure Management (EM) framework. We feel it's more than a worthwhile read an...
