Cybersecurity researchers have disclosed details of a new Android remote access trojan (RAT) called Fantasy Hub that's sold on Russian-speaking Telegram channels under a Malware-as-a-Service (MaaS) model. According to its seller, the malware enables device control and espionage, allowing threat actors to collect SMS messages, contacts, call logs, images, and videos, as well as intercept, reply, and delete incoming notifications. "It's a MaaS product with seller documentation, videos, and a bot-driven subscription model that helps novice attackers by providing a low barrier to entry," Zimperium researcher Vishnu Pratapagiri said in a report last week. "Because it targets financial workflows (fake windows for banks) and abuses the SMS handler role (for intercepting 2-factor SMS), it poses a direct threat to enterprise customers using BYOD and to any organization whose employees rely on mobile banking or sensitive mobile apps." The threat actor, in their...

Google's Mandiant Threat Defense on Monday said it discovered n-day exploitation of a now-patched security flaw in Gladinet's Triofox file-sharing and remote access platform. The critical vulnerability, tracked as CVE-2025-12480 (CVSS score: 9.1), allows an attacker to bypass authentication and access the configuration pages, resulting in the upload and execution of arbitrary payloads.  The tech giant said it observed a threat cluster tracked as UNC6485 weaponizing the flaw as far back as August 24, 2025, nearly a month after Gladinet released patches for the flaw in version 16.7.10368.56560 . It's worth noting that CVE-2025-12480 is the third flaw in Triofox that has come under active exploitation this year alone, after CVE-2025-30406 and CVE-2025-11371 . "Added protection for the initial configuration pages," according to release notes for the software. "These pages can no longer be accessed after Triofox has been set up." Mandiant said the th...

The North Korea-affiliated threat actor known as Konni (aka Earth Imp, Opal Sleet, Osmium, TA406, and Vedalia) has been attributed to a new set of attacks targeting both Android and Windows devices for data theft and remote control. "Attackers impersonated psychological counselors and North Korean human rights activists, distributing malware disguised as stress-relief programs," the Genians Security Center (GSC) said in a technical report. What's notable about the attacks targeting Android devices is also the destructive ability of the threat actors to exploit Google's asset tracking services Find Hub (formerly Find My Device) to remotely reset victim devices, thereby leading to the unauthorized deletion of personal data. The activity was detected in early September 2025. The development marks the first time the hacking group has weaponized legitimate management functions to remotely reset mobile devices. The activity is also preceded by an attack chain in whic...

Cyber threats didn't slow down last week—and attackers are getting smarter. We're seeing malware hidden in virtual machines, side-channel leaks exposing AI chats, and spyware quietly targeting Android devices in the wild. But that's just the surface. From sleeper logic bombs to a fresh alliance between major threat groups, this week's roundup highlights a clear shift: cybercrime is evolving fast, and the lines between technical stealth and strategic coordination are blurring. It's worth your time. Every story here is about real risks that your team needs to know about right now. Read the whole recap. ⚡ Threat of the Week Curly COMrades Abuses Hyper-V to Hide Malware in Linux VMs — Curly COMrades, a threat actor supporting Russia's geopolitical interests, has been observed abusing Microsoft's Hyper-V hypervisor in compromised Windows machines to create a hidden Alpine Linux-based virtual machine and deploy malicious payloads. This method allows the malware to run completel...

According to the new Browser Security Report 2025 , security leaders are discovering that most identity, SaaS, and AI-related risks converge in a single place, the user's browser. Yet traditional controls like DLP, EDR, and SSE still operate one layer too low. What's emerging isn't just a blindspot. It's a parallel threat surface: unmanaged extensions acting like supply chain implants, GenAI tools accessed through personal accounts, sensitive data copy/pasted directly into prompt fields, and sessions that bypass SSO altogether. This article unpacks the key findings from the report and what they reveal about the shifting locus of control in enterprise security. GenAI Is Now the Top Data Exfiltration Channel The rise of GenAI in enterprise workflows has created a massive governance gap. Nearly half of employees use GenAI tools, but most do so through unmanaged accounts, outside of IT visibility. Key stats from the report: 77% of employees paste data into GenAI prompts 82% of...

Cybersecurity researchers have called attention to a massive phishing campaign targeting the hospitality industry that lures hotel managers to ClickFix-style pages and harvest their credentials by deploying malware like PureRAT . "The attacker's modus operandi involved using a compromised email account to send malicious messages to multiple hotel establishments," Sekoia said . "This campaign leverages spear-phishing emails that impersonate Booking.com to redirect victims to malicious websites, employing the ClickFix social engineering tactic to deploy PureRAT." The end goal of the campaign is to steal credentials from compromised systems that grant threat actors unauthorized access to booking platforms like Booking.com or Expedia, which are then either sold on cybercrime forums or used to send fraudulent emails to hotel customers to conduct fraud. The activity is assessed to be active since at least April 2025 and operational as of early October 2025. It...

Cybersecurity researchers have disclosed a new set of three extensions associated with the GlassWorm campaign, indicating continued attempts on part of threat actors to target the Visual Studio Code (VS Code) ecosystem. The extensions in question , which are still available for download, are listed below - ai-driven-dev.ai-driven-dev (3,402 downloads) adhamu.history-in-sublime-merge (4,057 downloads) yasuyuky.transient-emacs (2,431 downloads) GlassWorm, first documented by Koi Security late last month, refers to a campaign in which threat actors leverage VS Code extensions on the Open VSX Registry and the Microsoft Extension Marketplace to harvest Open VSX, GitHub, and Git credentials, drain funds from 49 different cryptocurrency wallet extensions, and drop additional tools for remote access. What makes the malware notable is that it uses invisible Unicode characters to hide malicious code in code editors and abuses the pilfered credentials to compromise additional extens...

Microsoft has disclosed details of a novel side-channel attack targeting remote language models that could enable a passive adversary with capabilities to observe network traffic to glean details about model conversation topics despite encryption protections under certain circumstances. This leakage of data exchanged between humans and streaming-mode language models could pose serious risks to the privacy of user and enterprise communications, the company noted. The attack has been codenamed Whisper Leak . "Cyber attackers in a position to observe the encrypted traffic (for example, a nation-state actor at the internet service provider layer, someone on the local network, or someone connected to the same Wi-Fi router) could use this cyber attack to infer if the user's prompt is on a specific topic," security researchers Jonathan Bar Or and Geoff McDonald, along with the Microsoft Defender Security Research Team, said . Put differently, the attack allows an attacker t...

A now-patched security flaw in Samsung Galaxy Android devices was exploited as a zero-day to deliver a "commercial-grade" Android spyware dubbed LANDFALL in targeted attacks in the Middle East. The activity involved the exploitation of CVE-2025-21042 (CVSS score: 8.8), an out-of-bounds write flaw in the "libimagecodec.quram.so" component that could allow remote attackers to execute arbitrary code, according to Palo Alto Networks Unit 42. The issue was addressed by Samsung in April 2025. "This vulnerability was actively exploited in the wild before Samsung patched it in April 2025, following reports of in-the-wild attacks," Unit 42 said . Potential targets of the activity, tracked as CL-UNK-1054, are located in Iraq, Iran, Turkey, and Morocco based on VirusTotal submission data. The development comes as Samsung disclosed in September 2025 that another flaw in the same library (CVE-2025-21043, CVSS score: 8.8) had also been exploited in the wild as a...

A China-linked threat actor has been attributed to a cyber attack targeting an U.S. non-profit organization with an aim to establish long-term persistence, as part of broader activity aimed at U.S. entities that are linked to or involved in policy issues. The organization, according to a report from Broadcom's Symantec and Carbon Black teams, is "active in attempting to influence U.S. government policy on international issues." The attackers managed to gain access to the network for several weeks in April 2025. The first sign of activity occurred on April 5, 2025, when mass scanning efforts were detected against a server by leveraging various well-known exploits, including CVE-2022-26134 (Atlassian), CVE-2021-44228 (Apache Log4j), CVE-2017-9805 (Apache Struts), and CVE-2017-17562 (GoAhead Web Server). Symantec and Carbon Black told The Hacker News that there is no indication that these exploitation efforts were successful. It's suspected that the attackers ul...

A set of nine malicious NuGet packages has been identified as capable of dropping time-delayed payloads to sabotage database operations and corrupt industrial control systems. According to software supply chain security company Socket, the packages were published in 2023 and 2024 by a user named " shanhai666 " and are designed to run malicious code after specific trigger dates in August 2027 and November 2028. The packages were collectively downloaded 9,488 times. "The most dangerous package, Sharp7Extend, targets industrial PLCs with dual sabotage mechanisms: immediate random process termination and silent write failures that begin 30-90 minutes after installation, affecting safety-critical systems in manufacturing environments," security researcher Kush Pandya said . The list of malicious packages is below - MyDbRepository (Last updated on May 13, 2023) MCDbRepository (Last updated on June 5, 2024) Sharp7Extend (Last updated on August 14, 2024) SqlDbRepo...

Imagine this: Sarah from accounting gets what looks like a routine password reset email from your organization's cloud provider. She clicks the link, types in her credentials, and goes back to her spreadsheet. But unknown to her, she's just made a big mistake. Sarah just accidentally handed over her login details to cybercriminals who are laughing all the way to their dark web marketplace, where they'll sell her credentials for about $15. Not much as a one-off, but a serious money-making operation when scaled up. The credential compromise lifecycle Users create credentials: With dozens of standalone business apps (each with its own login) your employees must create numerous accounts. But keeping track of multiple unique usernames/passwords is a pain, so they reuse passwords or make tiny variations. Hackers compromise credentials: Attackers snag these credentials through phishing, brute force attacks, third-party breaches, or exposed API keys. And many times, no...

Google on Thursday said it's rolling out a dedicated form to allow businesses listed on Google Maps to report extortion attempts made by threat actors who post inauthentic bad reviews on the platform and demand ransoms to remove the negative comments. The approach is designed to tackle a common practice called review bombing , where online users intentionally post negative user reviews in an attempt to harm a product, a service, or a business. "Bad actors try to circumvent our moderation systems and flood a business's profile with fake one-star reviews," Laurie Richardson, vice president of Trust & Safety at Google, said . "Following this initial attack, the scammers directly contact the business owner, often through third-party messaging apps, to demand payment." The threat actors warn of further escalation should the victim fail to pay the fee, risking potential damage to their public rating and reputation. These ploys are seen as an attempt to coe...
