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...

Redis has disclosed details of a maximum-severity security flaw in its in-memory database software that could result in remote code execution under certain circumstances. The vulnerability, tracked as CVE-2025-49844 (aka RediShell), has been assigned a CVSS score of 10.0. "An authenticated user may use a specially crafted Lua script to manipulate the garbage collector, trigger a use-after-free, and potentially lead to remote code execution," according to a GitHub advisory for the issue. "The problem exists in all versions of Redis with Lua scripting." However, for exploitation to be successful, it requires an attacker to first gain authenticated access to a Redis instance, making it crucial that users don't leave their Redis instances exposed to the internet and secure them with strong authentication. The issue impacts all versions of Redis. It has been addressed in versions 6.2.20, 7.2.11, 7.4.6, 8.0.4, and 8.2.2 released on October 3, 2025. As tempor...

CrowdStrike on Monday said it's attributing the exploitation of a recently disclosed security flaw in Oracle E-Business Suite with moderate confidence to a threat actor it tracks as Graceful Spider (aka Cl0p ), and that the first known exploitation occurred on August 9, 2025. The malicious activity involves the exploitation of CVE-2025-61882 (CVSS score: 9.8), a critical vulnerability that facilitates remote code execution without authentication. The cybersecurity company also noted that it's currently not known how a Telegram channel "insinuating" collaboration between Scattered Spider, LAPSUS$ (aka Slippy Spider), and ShinyHunters came into the possession of an exploit for the flaw, and if they and other threat actors have leveraged it in real-world attacks. The Telegram channel has been observed sharing the purported Oracle EBS exploit, while criticizing Graceful Spider's tactics. It's worth noting that the binaries dropped by the Cl0p actors contain...

A Chinese company named the Beijing Institute of Electronics Technology and Application (BIETA) has been assessed to be likely led by the Ministry of State Security (MSS). The assessment comes from evidence that at least four BIETA personnel have clear or possible links to MSS officers and their relationship with the University of International Relations, which is known to share links with the MSS, according to Recorded Future.

In the era of rapidly advancing artificial intelligence (AI) and cloud technologies, organizations are increasingly implementing security measures to protect sensitive data and ensure regulatory compliance. Among these measures, AI-SPM (AI Security Posture Management) solutions have gained traction to secure AI pipelines, sensitive data assets, and the overall AI ecosystem. These solutions help organizations identify risks, control security policies, and protect data and algorithms critical to their operations.  However, not all AI-SPM tools are created equal. When evaluating potential solutions, organizations often struggle to pinpoint which questions to ask to make an informed decision. To help you navigate this complex space, here are five critical questions every organization should ask when selecting an AI-SPM solution: 1: Does the solution offer comprehensive visibility and control over AI and associated data risk? With the proliferation of AI models across enterprises, m...

Oracle has released an emergency update to address a critical security flaw in its E-Business Suite software that it said has been exploited in the recent wave of Cl0p data theft attacks. The vulnerability, tracked as CVE-2025-61882 (CVSS score: 9.8), concerns an unspecified bug that could allow an unauthenticated attacker with network access via HTTP to compromise and take control of the Oracle Concurrent Processing component.

Cybersecurity researchers have shed light on a Chinese-speaking cybercrime group codenamed UAT-8099 that has been attributed to search engine optimization (SEO) fraud and theft of high-value credentials, configuration files, and certificate data.  The attacks are designed to target Microsoft Internet Information Services (IIS) servers, with most of the infections reported in India, Thailand, Vietnam, Canada, and Brazil, spanning universities, tech firms, and telecom providers. The group was first discovered in April 2025. The targets are primarily mobile users, encompassing both Android and Apple iPhone devices. UAT-8099 is the latest China-linked actor to engage in SEO fraud for financial gain. As recently as last month, ESET revealed details of another threat actor named GhostRedirector that has managed to compromise at least 65 Windows servers primarily located in Brazil, Thailand, and Vietnam with a malicious IIS module codenamed Gamshen to facilitate SEO fraud. "UAT-809...

A now patched security vulnerability in Zimbra Collaboration was exploited as a zero-day earlier this year in cyber attacks targeting the Brazilian military. Tracked as CVE-2025-27915 (CVSS score: 5.4), the vulnerability is a stored cross-site scripting (XSS) vulnerability in the Classic Web Client that arises as a result of insufficient sanitization of HTML content in ICS calendar files, resulting in arbitrary code execution. "When a user views an e-mail message containing a malicious ICS entry, its embedded JavaScript executes via an ontoggle event inside a <details> tag," according to a description of the flaw in the NIST National Vulnerability Database (NVD). "This allows an attacker to run arbitrary JavaScript within the victim's session, potentially leading to unauthorized actions such as setting e-mail filters to redirect messages to an attacker-controlled address. As a result, an attacker can perform unauthorized actions on the victim's acco...

Cybersecurity researchers have disclosed details of a new attack called CometJacking targeting Perplexity's agentic AI browser Comet by embedding malicious prompts within a seemingly innocuous link to siphon sensitive data, including from connected services, like email and calendar. The sneaky prompt injection attack plays out in the form of a malicious link that, when clicked, triggers the unexpected behavior unbeknownst to the victims. "CometJacking shows how a single, weaponized URL can quietly flip an AI browser from a trusted co-pilot to an insider threat," Michelle Levy, Head of Security Research at LayerX, said in a statement shared with The Hacker News. "This isn't just about stealing data; it's about hijacking the agent that already has the keys. Our research proves that trivial obfuscation can bypass data exfiltration checks and pull email, calendar, and connector data off-box in one click. AI-native browsers need security-by-design for agent...

Threat intelligence firm GreyNoise disclosed on Friday that it has observed a massive spike in scanning activity targeting Palo Alto Networks login portals. The company said it observed a nearly 500% increase in IP addresses scanning Palo Alto Networks login portals on October 3, 2025, the highest level recorded in the last three months. It described the traffic as targeted and structured, and aimed primarily at Palo Alto login portals. As many as 1,300 unique IP addresses have participated in the effort, a significant jump from around 200 unique IP addresses observed before. Of these IP addresses, 93% are classified as suspicious and 7% as malicious. The vast majority of the IP addresses are geolocated to the U.S., with smaller clusters detected in the U.K., the Netherlands, Canada, and Russia. "This Palo Alto surge shares characteristics with Cisco ASA scanning occurring in the past 48 hours," GreyNoise noted. "In both cases, the scanners exhibited regional clu...

A threat actor named Detour Dog has been outed as powering campaigns distributing an information stealer known as Strela Stealer. That's according to findings from Infoblox, which found the threat actor to maintain control of domains hosting the first stage of the stealer, a backdoor called StarFish. The DNS threat intelligence firm said it has been tracking Detour Dog since August 2023, when GoDaddy-owned Sucuri disclosed details of attacks targeting WordPress sites to embed malicious JavaScript that used DNS TXT records as a communication channel for a traffic distribution system (TDS), redirecting site visitors to sketchy sites and malware. Traces of the threat actor date back to February 2020. "While traditionally these redirects led to scams, the malware has evolved recently to execute remote content through the DNS-based command-and-control (C2) system," Infoblox said . "We are tracking the threat actor who controls this malware as Detour Dog." Det...
