Hackers Exploiting Redis Vulnerability to Deploy New Redigo Malware on Servers

A previously undocumented Go-based malware is targeting Redis servers with the goal of taking control of the infected systems and likely building a botnet network. The attacks involve taking advantage of a critical security vulnerability in the open source, in-memory, key-value store that was disclosed earlier this year to deploy Redigo, according to cloud security firm Aqua. <!--adsense-->

Researchers 'Accidentally’ Crash KmsdBot Cryptocurrency Mining Botnet Network

An ongoing analysis into an up-and-coming cryptocurrency mining botnet known as KmsdBot has led to it being accidentally taken down. KmsdBot, as christened by the Akamai Security Intelligence Response Team (SIRT), came to light mid-November 2022 for its ability to brute-force systems with weak SSH credentials. The botnet strikes both Windows and Linux devices spanning a wide range of

CISA Warns of Actively Exploited Critical Oracle Fusion Middleware Vulnerability

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a critical flaw impacting Oracle Fusion Middleware to its Known Exploited Vulnerabilities (KEV) Catalog, citing evidence of active exploitation. The vulnerability, tracked as CVE-2021-35587, carries a CVSS score of 9.8 and impacts Oracle Access Manager (OAM) versions 11.1.2.3.0, 12.2.1.3.0, and 12.2.1.4.0. <!--

All You Need to Know About Emotet in 2022

Let's dive into details and discuss all you need to know about the notorious malware to combat it. Why is everyone scared of Emotet? Emotet is by far one of the most dangerous trojans ever created. The malware became a very destructive program as it grew in scale and sophistication.

Hackers Exploiting Abandoned Boa Web Servers to Target Critical Industries

Microsoft on Tuesday disclosed the intrusion activity aimed at Indian power grid entities earlier this year likely involved the exploitation of security flaws in a now-discontinued web server called Boa. The tech behemoth's cybersecurity division said the vulnerable component poses a "supply chain risk that may affect millions of organizations and devices." The findings build on a prior report 

Google Wins Lawsuit Against Russians Linked to Blockchain-based Glupteba Botnet

Google has won a lawsuit filed against two Russian nationals in connection with the operation of a botnet called Glupteba, the company said last week. The U.S. District Court for the Southern District of New York imposed monetary sanctions against the defendants and their U.S.-based legal counsel. The defendants have also been asked to pay Google's attorney fees. The defendants' move to press

Warning: New RapperBot Campaign Aims to Launch DDoS Attacks at Game Servers

Cybersecurity researchers have unearthed new samples of malware called RapperBot that are being used to build a botnet capable of launching Distributed Denial of Service (DDoS) attacks against game servers. "In fact, it turns out that this campaign is less like RapperBot than an older campaign that appeared in February and then mysteriously disappeared in the middle of April," Fortinet

Fodcha DDoS Botnet Resurfaces with New Capabilities

The threat actor behind the Fodcha distributed denial-of-service (DDoS) botnet has resurfaced with new capabilities, researchers reveal. This includes changes to its communication protocol and the ability to extort cryptocurrency payments in exchange for stopping the DDoS attack against a target, Qihoo 360's Network Security Research Lab said in a report published last week.
