The company, however, makes no mention of it being exploited in the wild. Oracle's Chi...

Cybersecurity researchers have disclosed details of an active malware campaign called Stealit that has leveraged Node.js' Single Executable Application (SEA) feature as a way to distribute its payloads. According to Fortinet FortiGuard Labs, select iterations have also employed the open-source Electron framework to deliver the malware. It's assessed that the malware is being propagated through counterfeit installers for games and VPN applications that are uploaded to file-sharing sites such as Mediafire and Discord. SEA is a feature that allows Node.js applications to be packaged and distributed as a standalone executable, even on systems without Node.js installed. "Both approaches are effective for distributing Node.js-based malware, as they allow execution without requiring a pre-installed Node.js runtime or additional dependencies," security researchers Eduardo Altares and Joie Salvio said in a report shared with The Hacker News. On a dedicated website, the...

Cybersecurity researchers have flagged a new set of 175 malicious packages on the npm registry that have been used to facilitate credential harvesting attacks as part of an unusual campaign. The packages have been collectively downloaded 26,000 times, acting as an infrastructure for a widespread phishing campaign codenamed Beamglea targeting more than 135 industrial, technology, and energy companies across the world, according to Socket. "While the packages' randomized names make accidental developer installation unlikely, the download counts likely include security researchers, automated scanners, and CDN infrastructure analyzing the packages after disclosure," security researcher Kush Pandya said . The packages have been found to use npm's public registry and unpkg.com's CDN to host redirect scripts that route victims to credential harvesting pages. Some aspects of the campaign were first flagged by Safety's Paul McCarty late last month. Specificall...

Dozens of organizations may have been impacted following the zero-day exploitation of a security flaw in Oracle's E-Business Suite (EBS) software since August 9, 2025 , Google Threat Intelligence Group (GTIG) and Mandiant said in a new report released Thursday. "We're still assessing the scope of this incident , but we believe it affected dozens of organizations," John Hultquist, chief analyst of GTIG at Google Cloud, said in a statement shared with The Hacker News. "Some historic Cl0p data extortion campaigns have had hundreds of victims. Unfortunately, large-scale zero-day campaigns like this are becoming a regular feature of cybercrime." The activity, which bears some hallmarks associated with the Cl0p ransomware crew, is assessed to have fashioned together multiple distinct vulnerabilities, including a zero-day flaw tracked as CVE-2025-61882 (CVSS score: 9.8), to breach target networks and exfiltrate sensitive data. Google said it found evidence of ...

A China-aligned threat actor codenamed UTA0388 has been attributed to a series of spear-phishing campaigns targeting North America, Asia, and Europe that are designed to deliver a Go-based implant known as GOVERSHELL . "The initially observed campaigns were tailored to the targets, and the messages purported to be sent by senior researchers and analysts from legitimate-sounding, completely fabricated organizations," Volexity said in a Wednesday report. "The goal of these spear phishing campaigns was to socially engineer targets into clicking links that led to a remotely hosted archive containing a malicious payload." Since then, the threat actor behind the attacks is said to have leveraged different lures and fictional identities, spanning several languages, including English, Chinese, Japanese, French, and German. Early iterations of the campaigns have been found to embed links to phishing content either hosted on a cloud-based service or their own infrastruc...

A rapidly evolving Android spyware campaign called ClayRat has targeted users in Russia using a mix of Telegram channels and lookalike phishing websites by impersonating popular apps like WhatsApp, Google Photos, TikTok, and YouTube as lures to install them. "Once active, the spyware can exfiltrate SMS messages, call logs, notifications, and device information; taking photos with the front camera; and even send SMS messages or place calls directly from the victim's device," Zimperium researcher Vishnu Pratapagiri said in a report shared with The Hacker News. The malware is also designed to propagate itself by sending malicious links to every contact in the victim's phone book, indicating aggressive tactics on the part of the attackers to leverage compromised devices as a distribution vector. The mobile security company said it has detected no less than 600 samples and 50 droppers over the last 90 days, with each successive iteration incorporating new layers of o...

Russian hackers' adoption of artificial intelligence (AI) in cyber attacks against Ukraine has reached a new level in the first half of 2025 (H1 2025), the country's State Service for Special Communications and Information Protection (SSSCIP) said. "Hackers now employ it not only to generate phishing messages, but some of the malware samples we have analyzed show clear signs of being generated with AI – and attackers are certainly not going to stop there," the agency said in a report published Wednesday. SSSCIP said 3,018 cyber incidents were recorded during the time period, up from 2,575 in the second half of 2024 (H2 2024). Local authorities and military entities witnessed an increase in attacks compared to H2 2024, while those targeting government and energy sectors declined. One notable attack observed involved UAC-0219's use of malware called WRECKSTEEL in attacks aimed at state administration bodies and critical infrastructure facilities in the country...

Threat actors are actively exploiting a critical security flaw impacting the Service Finder WordPress theme that makes it possible to gain unauthorized access to any account, including administrators, and take control of susceptible sites. The authentication bypass vulnerability, tracked as CVE-2025-5947 (CVSS score: 9.8), affects the Service Finder Bookings, a WordPress plugin bundled with the Service Finder theme. It was discovered by a researcher who goes by the name Foxyyy. "This vulnerability makes it possible for an unauthenticated attacker to gain access to any account on a site, including accounts with the 'administrator' role," Wordfence researcher István Márton said . The problem, at its core, is a case of privilege escalation stemming from authentication bypass due to the plugin not adequately validating a user's cookie value before logging them in through an account switching function (service_finder_switch_back()). As a result, an unauthenticate...

Cybersecurity researchers are calling attention to a nefarious campaign targeting WordPress sites to make malicious JavaScript injections that are designed to redirect users to sketchy sites. "Site visitors get injected content that was drive-by malware like fake Cloudflare verification," Sucuri researcher Puja Srivastava said in an analysis published last week. The website security company said it began an investigation after one of its customer's WordPress sites served suspicious third-party JavaScript to site visitors, ultimately finding that the attackers introduced malicious modifications to a theme-related file ("functions.php"). The code inserted into "functions.php" incorporates references to Google Ads, likely in an attempt to evade detection. But, in reality, it functions as a remote loader by sending an HTTP POST request to the domain "brazilc[.]com," which, in turn, responds with a dynamic payload that includes two component...

Threat actors with suspected ties to China have turned a legitimate open-source monitoring tool called Nezha into an attack weapon, using it to deliver a known malware called Gh0st RAT to targets. The activity, observed by cybersecurity company Huntress in August 2025, is characterized by the use of an unusual technique called log poisoning (aka log injection) to plant a web shell on a web server. "This allowed the threat actor to control the web server using ANTSWORD , before ultimately deploying Nezha, an operation and monitoring tool that allows commands to be run on a web server," researchers Jai Minton, James Northey, and Alden Schmidt said in a report shared with The Hacker News. In all, the intrusion is said to have likely compromised more than 100 victim machines, with a majority of the infections reported in Taiwan, Japan, South Korea, and Hong Kong. "The activity has been going on since at least June of 2025 but it may have been longer," Minton, ...

Three prominent ransomware groups DragonForce , LockBit , and Qilin have announced a new strategic ransomware alliance, once underscoring continued shifts in the cyber threat landscape. The coalition is seen as an attempt on the part of the financially motivated threat actors to conduct more effective ransomware attacks, ReliaQuest said in a report shared with The Hacker News. "Announced shortly after LockBit's return, the collaboration is expected to facilitate the sharing of techniques, resources, and infrastructure, strengthening each group's operational capabilities," the company noted in its ransomware report for Q3 2025. "This alliance could help restore LockBit's reputation among affiliates following last year's takedown, potentially triggering a surge in attacks on critical infrastructure and expanding the threat to sectors previously considered low risk." The partnership with Qilin is no surprise, given that it has become the most a...

OpenAI on Tuesday said it disrupted three activity clusters for misusing its ChatGPT artificial intelligence (AI) tool to facilitate malware development. This includes a Russian‑language threat actor, who is said to have used the chatbot to help develop and refine a remote access trojan (RAT), a credential stealer with an aim to evade detection. The operator also used several ChatGPT accounts to prototype and troubleshoot technical components that enable post‑exploitation and credential theft. "These accounts appear to be affiliated with Russian-speaking criminal groups, as we observed them posting evidence of their activities in a Telegram channel dedicated to those actors," OpenAI said. The AI company said while its large language models (LLMs) refused the threat actor's direct requests to produce malicious content, they worked around the limitation by creating building-block code, which was then assembled to create the workflows. Some of the produced output invo...

A Vietnamese threat actor named BatShadow has been attributed to a new campaign that leverages social engineering tactics to deceive job seekers and digital marketing professionals to deliver a previously undocumented malware called Vampire Bot. "The attackers pose as recruiters, distributing malicious files disguised as job descriptions and corporate documents," Aryaka Threat Research Labs researchers Aditya K Sood and Varadharajan K said in a report shared with The Hacker News. "When opened, these lures trigger the infection chain of a Go-based malware." The attack chains, per the cybersecurity company, leverage ZIP archives containing decoy PDF documents along with malicious shortcut (LNK) or executable files that are masked as PDF to trick users into opening them. When launched, the LNK file runs an embedded PowerShell script that reaches out to an external server to download a lure document, a PDF for a marketing job at Marriott. The PowerShell script al...

Cybersecurity researchers have charted the evolution of XWorm malware, turning it into a versatile tool for supporting a wide range of malicious actions on compromised hosts. "XWorm's modular design is built around a core client and an array of specialized components known as plugins," Trellix researchers Niranjan Hegde and Sijo Jacob said in an analysis published last week. "These plugins are essentially additional payloads designed to carry out specific harmful actions once the core malware is active." XWorm, first observed in 2022 and linked to a threat actor named EvilCoder, is a Swiss Army knife of malware that can facilitate data theft, keylogging, screen capture, persistence, and even ransomware operations. It's primarily propagated via phishing emails and bogus sites advertising malicious ScreenConnect installers. Some of the other tools advertised by the developer include a .NET-based malware builder, a remote access trojan called XBinder, a...

Microsoft on Monday attributed a threat actor it tracks as Storm-1175 to the exploitation of a critical security flaw in Fortra GoAnywhere software to facilitate the deployment of Medusa ransomware. The vulnerability is CVE-2025-10035 (CVSS score: 10.0), a critical deserialization bug that could result in command injection without authentication. It was addressed in version 7.8.4, or the Sustain Release 7.6.3.
