Threat actors have been observed concealing malicious code in images to deliver malware such as VIP Keylogger and 0bj3ctivity Stealer as part of separate campaigns. "In both campaigns, attackers hid malicious code in images they uploaded to archive[.]org, a file-hosting website, and used the same .NET loader to install their final payloads," HP Wolf Security said in its Threat Insights Report for Q3 2024 shared with The Hacker News. The starting point is a phishing email that masquerades as invoices and purchase orders to trick recipients into opening malicious attachments, such as Microsoft Excel documents, that, when opened, exploits a known security flaw in Equation Editor ( CVE-2017-11882 ) to download a VBScript file. The script, for its part, is designed to decode and run a PowerShell script that retrieves an image hosted on archive[.]org and extracts a Base64-encoded code, which is subsequently decoded into a .NET executable and executed. The .NET executable ser...

Cybersecurity researchers have detailed an attack that involved a threat actor utilizing a Python-based backdoor to maintain persistent access to compromised endpoints and then leveraged this access to deploy the RansomHub ransomware throughout the target network. According to GuidePoint Security , initial access is said to have been facilitated by means of a JavaScript malware downloaded named SocGholish (aka FakeUpdates), which is known to be distributed via drive-by campaigns that trick unsuspecting users into downloading bogus web browser updates. Such attacks commonly involve the use of legitimate-but-infected websites that victims are redirected to from search engine results using black hat Search Engine Optimization (SEO) techniques. Upon execution, SocGholish establishes contact with an attacker-controlled server to retrieve secondary payloads. As recently as last year, SocGholish campaigns have targeted WordPress sites relying on outdated versions of popular SEO plug...

Why does ICS/OT need specific controls and its own cybersecurity budget today? Because treating ICS/OT security with an IT security playbook isn't just ineffective—it's high risk. In the rapidly evolving domain of cybersecurity, the specific challenges and needs for Industrial Control Systems (ICS) and Operational Technology (OT) security distinctly stand out from traditional IT security. ICS/OT engineering systems, which power critical infrastructure such as electric power grids, oil and gas processing, heavy manufacturing, food and beverage processes, and water management facilities, require tailored cybersecurity strategies, and controls. This is due to the increasing attacks towards ICS/OT, their unique operational missions, a different risk surface than that of traditional IT networks, and the significant safety consequences from cyber incidents that impact the physical world. Critical infrastructure should be protected against today's threats to continue supporting national sa...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added a second security flaw impacting BeyondTrust Privileged Remote Access (PRA) and Remote Support (RS) products to the Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation in the wild. The vulnerability in question is CVE-2024-12686 (CVSS score: 6.6), a medium-severity bug that could allow an attacker with existing administrative privileges to inject commands and run as a site user. "BeyondTrust Privileged Remote Access (PRA) and Remote Support (RS) contain an OS command injection vulnerability that can be exploited by an attacker with existing administrative privileges to upload a malicious file," CISA said. "Successful exploitation of this vulnerability can allow a remote attacker to execute underlying operating system commands within the context of the site user." The addition of CVE-2024-12686 to the KEV catalog comes nearly a month after it a...

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 ...

The U.S. Department of Justice (DoJ) on Friday indicted three Russian nationals for their alleged involvement in operating the cryptocurrency mixing services Blender.io and Sinbad.io. Roman Vitalyevich Ostapenko and Alexander Evgenievich Oleynik were arrested on December 1, 2024, in coordination with the Netherlands' Financial Intelligence and Investigative Service, Finland's National Bureau of Investigation, and the U.S. Federal Bureau of Investigation (FBI). It was not revealed from where they were apprehended. The third individual, Anton Vyachlavovich Tarasov, is still at large. The defendants have been accused of operating cryptocurrency mixers (aka tumblers) that served as safe havens for "laundering criminally derived funds," including the proceeds of ransomware and wire fraud, thereby allowing state-sponsored hacking groups and cybercriminals to profit off their malicious operations. Specifically, they allowed their paying users to send cryptocurrency to ...

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...

Cybersecurity researchers have shed light on a new remote access trojan called NonEuclid that allows bad actors to remotely control compromised Windows systems. "The NonEuclid remote access trojan (RAT), developed in C#, is a highly sophisticated malware offering unauthorised remote access with advanced evasion techniques," Cyfirma said in a technical analysis published last week. "It employs various mechanisms, including antivirus bypass, privilege escalation, anti-detection, and ransomware encryption targeting critical files." NonEuclid has been advertised in underground forums since at least late November 2024, with tutorials and discussions about the malware discovered on popular platforms like Discord and YouTube. This points to a concerted effort to distribute the malware as a crimeware solution. At its core, the RAT commences with an initialization phase for a client application, after which it performs a series of checks to evade detection prior to s...

Cybersecurity researchers have uncovered firmware security vulnerabilities in the Illumina iSeq 100 DNA sequencing instrument that, if successfully exploited, could permit attackers to brick or plant persistent malware on susceptible devices. "The Illumina iSeq 100 used a very outdated implementation of BIOS firmware using CSM [Compatibility Support Mode] mode and without Secure Boot or standard firmware write protections," Eclypsium said in a report shared with The Hacker News. "This would allow an attacker on the system to overwrite the system firmware to either 'brick' the device or install a firmware implant for ongoing attacker persistence." While the Unified Extensible Firmware Interface ( UEFI ) is the modern replacement for the Basic Input/Output System (BIOS), the firmware security company said the iSeq 100 boots to an old version of BIOS (B480AM12 - 04/12/2018) that has known vulnerabilities. Also noticeably absent are protections to tell t...
