DDoS 2.0: IoT Sparks New DDoS Alert

DDoS 2.0: IoT Sparks New DDoS Alert

Sep 15, 2023 IoT Security / Cyber Threat
The  Internet of Things (IoT)  is transforming efficiency in various sectors like healthcare and logistics but has also introduced new security risks, particularly IoT-driven DDoS attacks. This article explores how these attacks work, why they're uniquely problematic, and how to mitigate them. What Is IoT? IoT (Internet of Things) refers to online, interconnected devices that collect and exchange data. This broad category of devices includes sensors, cameras, network routers, and advanced machinery, and their integration into everyday life and work processes results in an ecosystem that can automate operations, improve decision-making, and enhance user experience. IoT: A Breeding Ground for Botnets IoT's rapid adoption amplifies its vulnerability, as poorly secured devices become easy prey for attackers and may become part of a botnet. Controlled by attackers, botnets can scale and rapidly execute various attacks, including DDoS, data theft, ad fraud, cryptocurrency mining, spam a
Sophisticated Phishing Campaign Deploying Agent Tesla, OriginBotnet, and RedLine Clipper

Sophisticated Phishing Campaign Deploying Agent Tesla, OriginBotnet, and RedLine Clipper

Sep 12, 2023 Endpoint Security / Malware
A sophisticated phishing campaign is using a Microsoft Word document lure to distribute a trifecta of threats, namely Agent Tesla, OriginBotnet, and RedLine Clipper, to gather a wide range of information from compromised Windows machines. "A phishing email delivers the Word document as an attachment, presenting a deliberately blurred image and a counterfeit reCAPTCHA to lure the recipient into clicking on it," Fortinet FortiGuard Labs researcher Cara Lin  said . Clicking on the image leads to the delivery of a loader from a remote server that, in turn, is designed to distribute OriginBotnet for keylogging and password recovery, RedLine Clipper for cryptocurrency theft, and Agent Tesla for harvesting sensitive information. The loader, written in .NET, employs a technique called binary padding by adding null bytes to increase the file's size to 400 MB in an attempt to evade detection by security software. The activation of the loader triggers a multi-stage process to

FBI Dismantles QakBot Malware, Frees 700,000 Computers, Seizes $8.6 Million

FBI Dismantles QakBot Malware, Frees 700,000 Computers, Seizes $8.6 Million

Aug 30, 2023 Malware / Cyber Crime
A coordinated law enforcement effort codenamed  Operation Duck Hunt  has felled  QakBot , a notorious Windows malware family that's estimated to have compromised over 700,000 computers globally and facilitated financial fraud as well as ransomware. To that end, the U.S. Justice Department (DoJ)  said  the malware is "being deleted from victim computers, preventing it from doing any more harm," adding it seized more than $8.6 million in cryptocurrency in illicit profits. The cross-border exercise involved the participation of France, Germany, Latvia, Romania, the Netherlands, the U.K., and the U.S., alongside technical assistance from cybersecurity company Zscaler. The dismantling has been hailed as "the largest U.S.-led financial and technical disruption of a botnet infrastructure leveraged by cybercriminals." No arrests were announced. QakBot, also known as QBot and Pinkslipbot, started its life as a banking trojan in 2007 before morphing into a general-pu
Thousands of Unpatched Openfire XMPP Servers Still Exposed to High-Severity Flaw

Thousands of Unpatched Openfire XMPP Servers Still Exposed to High-Severity Flaw

Aug 24, 2023 Cyber Attack / Vulnerability
Thousands of  Openfire XMPP servers  are unpatched against a recently disclosed high-severity flaw and are susceptible to a new exploit, according to a  new report  from VulnCheck. Tracked as  CVE-2023-32315  (CVSS score: 7.5), the vulnerability relates to a path traversal vulnerability in Openfire's administrative console that could permit an unauthenticated attacker to access otherwise restricted pages reserved for privileged users. It affects all versions of the software released since April 2015, starting with version 3.10.0. It was remediated by its developer, Ignite Realtime, earlier this May with the release of versions 4.6.8, 4.7.5, and 4.8.0. "Path traversal protections were already in place to protect against exactly this kind of attack, but didn't defend against certain non-standard URL encoding for UTF-16 characters that were not supported by the embedded web server that was in use at the time," the maintainers  said  in a detailed advisory. "A
New SkidMap Linux Malware Variant Targeting Vulnerable Redis Servers

New SkidMap Linux Malware Variant Targeting Vulnerable Redis Servers

Aug 07, 2023 Data Security / Linux
Vulnerable  Redis services  have been targeted by a "new, improved, dangerous" variant of a malware called SkidMap that's engineered to target a wide range of Linux distributions. "The malicious nature of this malware is to adapt to the system on which it is executed," Trustwave security researcher Radoslaw Zdonczyk  said  in an analysis published last week. Some of the Linux distribution SkidMap sets its eyes on include Alibaba, Anolis, openEuler, EulerOS, Stream, CentOS, RedHat, and Rocky. SkidMap was  first disclosed  by Trend Micro in September 2019 as a cryptocurrency mining botnet with capabilities to load malicious kernel modules that can obfuscate its activities as well as monitor the miner process. The operators of the malware have also been found camouflaging their backup command-and-control (C2) IP address on the Bitcoin blockchain, evocative of another botnet malware known as  Glupteba . "The technique of fetching real-time data from a de
