Ransomware on ESXi: The Mechanization of Virtualized Attacks

Ransomware on ESXi: The Mechanization of Virtualized Attacks

Jan 13, 2025 Threat Detection / Network Security
In 2024, ransomware attacks targeting VMware ESXi servers reached alarming levels, with the average ransom demand skyrocketing to $5 million. With approximately 8,000 ESXi hosts exposed directly to the internet (according to Shodan), the operational and business impact of these attacks is profound. Most of the Ransomware strands that are attacking ESXi servers nowadays, are variants of the infamous Babuk ransomware, adapted to avoid detection of security tools. Moreover, accessibility is becoming more widespread, as attackers monetize their entry points by selling Initial Access to other threat actors, including ransomware groups. As organizations are dealing with compounded threats on an ever-expanding front: new vulnerabilities, new entry points, monetized cyber-crime networks, and more, there is ever-growing urgency for enhanced security measures and vigilance. The architecture of ESXi Understanding how an attacker can gain control of the ESXi host begins with understanding the ...

WordPress Skimmers Evade Detection by Injecting Themselves into Database Tables

WordPress Skimmers Evade Detection by Injecting Themselves into Database Tables

Jan 13, 2025 Payment Security / Web Security
Cybersecurity researchers are warning of a new stealthy credit card skimmer campaign that targets WordPress e-commerce checkout pages by inserting malicious JavaScript code into a database table associated with the content management system (CMS). "This credit card skimmer malware targeting WordPress websites silently injects malicious JavaScript into database entries to steal sensitive payment details," Sucuri researcher Puja Srivastava said in a new analysis. "The malware activates specifically on checkout pages, either by hijacking existing payment fields or injecting a fake credit card form." The GoDaddy-owned website security company said it discovered the malware embedded into the WordPress wp_options table with the option "widget_block," thus allowing it to avoid detection by scanning tools and persist on compromised sites without attracting attention. In doing so, the idea is to insert the malicious JavaScript into an HTML block widget thr...
Expired Domains Allowed Control Over 4,000 Backdoors on Compromised Systems

Expired Domains Allowed Control Over 4,000 Backdoors on Compromised Systems

Jan 13, 2025 Malware / Domain Security
No less than 4,000 unique web backdoors previously deployed by various threat actors have been hijacked by taking control of abandoned and expired infrastructure for as little as $20 per domain. Cybersecurity company watchTowr Labs said it pulled off the operation by registering over 40 domain names that the backdoors had been designed to use for command-and-control (C2). In partnership with the Shadowserver Foundation, the domains implicated in the research have been sinkholed. "We have been hijacking backdoors (that were reliant on now abandoned infrastructure and/or expired domains) that themselves existed inside backdoors, and have since been watching the results flood in," watchTowr Labs CEO Benjamin Harris and researcher Aliz Hammond said in a technical write-up last week. "This hijacking allowed us to track compromised hosts as they 'reported in,' and theoretically gave us the power to commandeer and control these compromised hosts." Among the ...
Microsoft Sues Hacking Group Exploiting Azure AI for Harmful Content Creation

Microsoft Sues Hacking Group Exploiting Azure AI for Harmful Content Creation

Jan 11, 2025 AI Security / Cybersecurity
Microsoft has revealed that it's pursuing legal action against a "foreign-based threat–actor group" for operating a hacking-as-a-service infrastructure to intentionally get around the safety controls of its generative artificial intelligence (AI) services and produce offensive and harmful content. The tech giant's Digital Crimes Unit (DCU) said it has observed the threat actors "develop sophisticated software that exploited exposed customer credentials scraped from public websites," and "sought to identify and unlawfully access accounts with certain generative AI services and purposely alter the capabilities of those services." The adversaries then used these services, such as Azure OpenAI Service, and monetized the access by selling them to other malicious actors, providing them with detailed instructions as to how to use these custom tools to generate harmful content. Microsoft said it discovered the activity in July 2024. The Windows maker...

AI-Driven Ransomware FunkSec Targets 85 Victims Using Double Extortion Tactics

Jan 10, 2025 Artificial Intelligence / Cybercrime
Cybersecurity researchers have shed light on a nascent artificial intelligence (AI) assisted ransomware family called FunkSec that sprang forth in late 2024, and has claimed more than 85 victims to date. "The group uses double extortion tactics, combining data theft with encryption to pressure victims into paying ransoms," Check Point Research said in a new report shared with The Hacker News. "Notably, FunkSec demanded unusually low ransoms, sometimes as little as $10,000, and sold stolen data to third parties at reduced prices." FunkSec launched its data leak site (DLS) in December 2024 to "centralize" their ransomware operations, highlighting breach announcements, a custom tool to conduct distributed denial-of-service (DDoS) attacks, and a bespoke ransomware as part of a ransomware-as-a-service (RaaS) model. A majority of the victims are located in the U.S., India, Italy, Brazil, Israel, Spain, and Mongolia. Check Point's analysis of the group...
