The newly released OpenAI ChatGPT Atlas web browser has been found to be susceptible to a prompt injection attack where its omnibox can be jailbroken by disguising a malicious prompt as a seemingly harmless URL to visit. "The omnibox (combined address/search bar) interprets input either as a URL to navigate to, or as a natural-language command to the agent," NeuralTrust said in a report published Friday. "We've identified a prompt injection technique that disguises malicious instructions to look like a URL, but that Atlas treats as high-trust 'user intent' text, enabling harmful actions." Last week, OpenAI launched Atlas as a web browser with built-in ChatGPT capabilities to assist users with web page summarization, inline text editing, and agentic functions. In the attack outlined by the artificial intelligence (AI) security company, an attacker can take advantage of the browser's lack of strict boundaries between trusted user input and untru...

Meta Platforms said it took a series of steps to curtail malicious activity from eight different firms based in Italy, Spain, and the United Arab Emirates (U.A.E.) operating in the surveillance-for-hire industry. The findings are part of its  Adversarial Threat Report  for the fourth quarter of 2023. The spyware targeted iOS, Android, and Windows devices. "Their various malware included capabilities to collect and access device information, location, photos and media, contacts, calendar, email, SMS, social media, and messaging apps, and enable microphone,camera, and screenshot functionality," the company said. The eight companies are Cy4Gate/ELT Group, RCS Labs, IPS Intelligence, Variston IT, TrueL IT, Protect Electronic Systems, Negg Group, and Mollitiam Industries. These firms, per Meta, also engaged in scraping, social engineering, and phishing activity that targeted a wide range of platforms such as Facebook, Instagram, X (formerly Twitter), YouTube, Skype, GitHub, R...

A number of D-Link routers reportedly have an issue that makes them susceptible to unauthorized backdoor access . The researcher Craig, specialized on the embedded device hacking - demonstrated the presence of a backdoor within some DLink routers that allows an attacker to access the administration web interface of network devices without any authentication and view/change its settings. He found the backdoor inside the firmware v1 . 13 for the DIR-100 revA . Craig found and extracted the SquashFS file system loading firmware's web server file system (/bin/webs) into IDA.  Giving a look at the string listing, the Craig's attention was captured by a modified version of thttpd , the thttpd - alphanetworks /2.23, implemented to provide the rights to the administrative interface for the router.  The library is written by Alphanetworks, a spin-off company of D-Link, analyzing it Craig found many custom functions characterized by a name starting with suffix "a...

Google has finally patched a privacy vulnerability in its Chrome web browser for Android that exposes users' device model and firmware version, eventually enabling remote attackers to identify unpatched devices and exploit known vulnerabilities. The vulnerability, which has not yet given any CVE number, is an information disclosure bug that resides in the way the Google Chrome for Android generates 'User Agent' string containing the Android version number and build tag information, which includes device name and its firmware build. This information is also sent to applications using WebView and Chrome Tabs APIs, which can be used to track users and fingerprint devices on which they are running. For example: Mozilla/5.0 (Linux; Android 5.1.1; Nexus 6 Build/LYZ28K ) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/46.0.2490.34 Mobile Safari/537.36 Yakov Shafranovich, a contributor at Nightwatch Cybersecurity firm, initially reported this issue to Google three years a...

The RIG exploit kit (EK) touched an all-time high successful exploitation rate of nearly 30% in 2022, new findings reveal. "RIG EK is a financially-motivated program that has been active since 2014," Swiss cybersecurity company PRODAFT  said  in an exhaustive report shared with The Hacker News. "Although it has yet to substantially change its exploits in its more recent activity, the type and version of the malware they distribute constantly change. The frequency of updating samples ranges from weekly to daily updates." Exploit kits are programs used to distribute malware to large numbers of victims by taking advantage of known security flaws in commonly-used software such as web browsers. The fact that  RIG EK  runs as a service model means threat actors can financially compensate the RIG EK administrator for installing malware of their choice on victim machines. The RIG EK operators primarily employ malvertising to ensure a high infection rate and large-scale...

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...

Attackers are increasingly turning to session hijacking to get around widespread MFA adoption. The data supports this , as: 147,000 token replay attacks were detected by Microsoft in 2023, a 111% increase year-over-year (Microsoft).  Attacks on session cookies now happen in the same order of magnitude as password-based attacks (Google). But session hijacking isn't a new technique – so what's changed? Session hijacking has a new look When we think of the classic example of session hijacking, we think of old-school Man-in-the-Middle (MitM) attacks that involved snooping on unsecured local network traffic to capture credentials or, more commonly, financial details like credit card data. Or, by conducting client-side attacks compromising a webpage, running malicious JavaScript and using cross-site scripting (XSS) to steal the victim's session ID.  Session hijacking looks quite different these days. No longer network-based, modern session hijacking is an identity-based att...

Yahoo! PH Purple Hunt 2.0 Ad Compromised ! Earlier the other day, I was browsing through the Yahoo! PH site and the Yahoo! Purple Hunt 2.0 ad caught my attention. Curious as I am, I clicked on the ad and surprisingly my browser downloaded a suspicious file named com.com. Apparently this ad redirected me to a randomly generated URL similar to the following which, unfortunately, led to the malicious download: hxxp://want6.{BLOCKED}.com/se/3da19bea8f9c03e96c9b1acad9cce5a88a2244f0a34d69 c09b8d3198b2797726789be0228c0df3c762ed088a2327b07f4a183fa6fa753b0acfd7f0afc2d2b 13b801ba978269fcda413f53e/960b0a2a/com.com hxxp://nose8.{BLOCKED}.com/se/3da19bea8f9c03e96c9b1acad9cce5a88a2244f0a34d69c 09b8d3198b2797726789be0228c0df3c762ed088a2327b07f4a183fa6fa753b0acfd7f0afc2d2b 13b801ba978269fcda413f53e/960b0a2a/com.com hxxp://letter6.{BLOCKED}.com/se/3da19bea8f9c03e96c9b1acad9cce5a88a2244f0a34d69c0 9b8d3198b2797726789be0228c0f3c762ed088a2327b07f4a183fa6fa753b0acfd7f0afc2d2b13 b801ba978269...

The North Korean threat actor known as Kimsuky has been linked to a new campaign that distributes a new variant of Android malware called DocSwap via QR codes hosted on phishing sites mimicking Seoul-based logistics firm CJ Logistics (formerly CJ Korea Express). "The threat actor leveraged QR codes and notification pop-ups to lure victims into installing and executing the malware on their mobile devices," ENKI said . "The malicious app decrypts an embedded encrypted APK and launches a malicious service that provides RAT capabilities." "Since Android blocks apps from unknown sources and displays security warnings by default, the threat actor claims the app is a safe, official release to trick victims into ignoring the warning and installing the malware." According to the South Korean cybersecurity company, some of these artifacts masquerade as package delivery service apps. It's being assessed that the threat actors are using smishing texts or phi...

Various sectors in East Asian markets have been subjected to a new email phishing campaign that distributes a previously undocumented strain of Android malware called  FluHorse  that abuses the Flutter software development framework. "The malware features several malicious Android applications that mimic legitimate applications, most of which have more than 1,000,000 installs," Check Point  said  in a technical report. "These malicious apps steal the victims' credentials and two-factor authentication (2FA) codes." The malicious apps have been found to imitate popular apps like ETC and VPBank Neo, which are widely used in Taiwan and Vietnam. Evidence gathered so far shows that the activity has been active since at least May 2022.  The phishing scheme in itself is fairly straightforward, wherein victims are lured with emails that contain links to a bogus website that hosts malicious APK files. Also added to the website are checks that aim to screen victi...

Cyber threats last week showed how attackers no longer need big hacks to cause big damage. They're going after the everyday tools we trust most — firewalls, browser add-ons, and even smart TVs — turning small cracks into serious breaches. The real danger now isn't just one major attack, but hundreds of quiet ones using the software and devices already inside our networks. Each trusted system can become an entry point if it's left unpatched or overlooked. Here's a clear look at the week's biggest risks, from exploited network flaws to new global campaigns and fast-moving vulnerabilities. ⚡ Threat of the Week Flaws in Multiple Network Security Products Come Under Attack — Over the past week, Fortinet , SonicWall , Cisco , and WatchGuard said vulnerabilities in their products have been exploited by threat actors in real-world attacks. Cisco said attacks exploiting CVE-2025-20393, a critical flaw in AsyncOS, have been abused by a China-nexus advanced persistent threat (APT) actor cod...

A China-based financially motivated group is leveraging the trust associated with popular international brands to orchestrate a large-scale phishing campaign dating back as far as 2019. The threat actor, dubbed Fangxiao by Cyjax, is said to have registered over  42,000 imposter domains , with initial activity observed in 2017. "It targets businesses in multiple verticals including retail, banking, travel, and energy," researchers Emily Dennison and Alana Witten  said . "Promised financial or physical incentives are used to trick victims into further spreading the campaign via WhatsApp." Users clicking on a link sent through the messaging app are directed to an actor-controlled site, which, in turn, sends them to a landing domain impersonating a well-known brand, from where the victims are once again taken to sites distributing fraudulent apps and bogus rewards. These sites prompt the visitors to complete a survey to claim cash prizes, in exchange for which the...

In October, A Security researcher ' Craig Heffner ' discovered a backdoor vulnerability ( CVE-2013-6027 ) with certain D-Link routers that allow cyber criminals to alter a router setting without a username or password. Last week, D-Link has released new version of Firmware for various vulnerable router models, that patches the unauthorized administrator access backdoor. Heffner  found that the web interface for some D-Link routers could be accessed if the browser's user agent string is set to xmlset_roodkcableoj28840ybtide . From last month, D-Link was working with Heffner and other security researchers, to find out more about the backdoor and now the Company has released the updates for the following models: DIR-100 DIR-120 DI-524 DI-524UP DI-604UP DI-604+ DI-624S TM-G5240 The company advised users to do not enable the Remote Management feature, since this will allow malicious users to use this exploit from the internet and also warned t...

A sophisticated phishing campaign is using a Microsoft Word document lure to distribute a trifecta of threats, namely Agent Tesla, OriginBotnet, and RedLine Clipper, to gather a wide range of information from compromised Windows machines. "A phishing email delivers the Word document as an attachment, presenting a deliberately blurred image and a counterfeit reCAPTCHA to lure the recipient into clicking on it," Fortinet FortiGuard Labs researcher Cara Lin  said . Clicking on the image leads to the delivery of a loader from a remote server that, in turn, is designed to distribute OriginBotnet for keylogging and password recovery, RedLine Clipper for cryptocurrency theft, and Agent Tesla for harvesting sensitive information. The loader, written in .NET, employs a technique called binary padding by adding null bytes to increase the file's size to 400 MB in an attempt to evade detection by security software. The activation of the loader triggers a multi-stage process to ...
