More than a dozen malicious packages have been discovered on the npm package repository since the start of August 2023 with capabilities to deploy an open-source information stealer called  Luna Token Grabber  on systems belonging to Roblox developers. The ongoing campaign, first detected on August 1 by ReversingLabs, employs modules that masquerade as the legitimate package  noblox.js , an API wrapper that's used to create scripts that interact with the Roblox gaming platform. The software supply chain security company described the activity as a "replay of an attack  uncovered  two years ago" in October 2021. "The malicious packages [...] reproduce code from the legitimate noblox.js package but add malicious, information-stealing functions," software threat researcher Lucija Valentić  said  in a Tuesday analysis. The packages were cumulatively downloaded 963 times before they were taken down. The names of the rogue packages are as follows - n...

A threat actor known as Stargazer Goblin has set up a network of inauthentic GitHub accounts to fuel a Distribution-as-a-Service (DaaS) that propagates a variety of information-stealing malware and netting them $100,000 in illicit profits over the past year. The network, which comprises over 3,000 accounts on the cloud-based code hosting platform, spans thousands of repositories that are used to share malicious links or malware, per Check Point, which has dubbed it "Stargazers Ghost Network." Some of the malware families propagated using this method include Atlantida Stealer, Rhadamanthys, RisePro, Lumma Stealer, and RedLine, with the bogus accounts also engaged in starring, forking, watching, and subscribing to malicious repositories to give them a veneer of legitimacy. The network is believed to have been active since August 2022 in some preliminary form, although an advertisement for the DaaS wasn't spotted in the dark until early July 2023. "Threat actors no...

A new Android-rooting malware with an ability to disable device' security settings in an effort to perform malicious tasks in the background has been detected on the official Play Store. What's interesting? The app was smart enough to fool Google security mechanism by first pretending itself to be a clean app and then temporarily replacing it with a malicious version. Security researchers at Kaspersky Lab discovered a new piece of Android rooting malware that was being distributed as gaming apps on the Google Play Store, hiding behind puzzle game " colourblock ," which was being downloaded at least 50,000 times prior to its removal. Dubbed Dvmap , the Android rooting malware disables device's security settings to install another malicious app from a third-party source and also injects malicious code into the device system runtime libraries to gain root access and stay persistent. "To bypass Google Play Store security checks, the malware creators used ...

Threat actors are continuing to upload malicious packages to the npm registry so as to tamper with already-installed local versions of legitimate libraries and execute malicious code in what's seen as a sneakier attempt to stage a software supply chain attack. The newly discovered package, named pdf-to-office , masquerades as a utility for converting PDF files to Microsoft Word documents. But, in reality, it harbors features to inject malicious code into cryptocurrency wallet software associated with Atomic Wallet and Exodus. "Effectively, a victim who tried to send crypto funds to another crypto wallet would have the intended wallet destination address swapped out for one belonging to the malicious actor," ReversingLabs researcher Lucija Valentić said in a report shared with The Hacker News. The npm package in question was first published on March 24, 2025, and has received three updates since then but not before the previous versions were likely removed by the a...

Next time when you see an advertisement of your favorite pair of shoes on any website, even if it is legitimate, just DO NOT CLICK ON IT. …Because that advertising could infect you in such a way that not just your system, but every device connected to your network would get affected. A few days ago, we reported about a new exploit kit, dubbed Stegano , that hides malicious code in the pixels of banner advertisements rotating on several high profile news websites. Now, researchers have discovered that attackers are targeting online users with an exploit kit called DNSChanger that is being distributed via advertisements that hide malicious code in image data. Remember DNSChanger? Yes, the same malware that infected millions of computers across the world in 2012. DNSChanger works by changing DNS server entries in infected computers to point to malicious servers under the control of the attackers, rather than the DNS servers provided by any ISP or organization. So, wheneve...

Cybersecurity researchers have discovered two malicious packages on the npm registry that are designed to infect another locally installed package, underscoring the continued evolution of software supply chain attacks targeting the open-source ecosystem. The packages in question are ethers-provider2 and ethers-providerz , with the former downloaded 73 times to date since it was published on March 15, 2025. The second package, likely removed by the malware author themselves, did not attract any downloads. "They were simple downloaders whose malicious payload was cleverly hidden," ReversingLabs researcher Lucija Valentić said in a report shared with The Hacker News. "The interesting part lay in their second stage, which would 'patch' the legitimate npm package ethers , installed locally, with a new file containing the malicious payload. That patched file would ultimately serve a reverse shell." The development marks a new escalation of threat actors...

As part of its "October Patch Tuesday," Microsoft has today released a large batch of security updates to patch a total of 62 vulnerabilities in its products, including a severe MS office zero-day flaw that has been exploited in the wild. Security updates also include patches for Microsoft Windows operating systems, Internet Explorer, Microsoft Edge, Skype, Microsoft Lync and Microsoft SharePoint Server. Besides the MS Office vulnerability, the company has also addressed two other publicly disclosed (but not yet targeted in the wild) vulnerabilities that affect the SharePoint Server and the Windows Subsystem for Linux. October patch Tuesday also fixes a critical Windows DNS vulnerability that could be exploited by a malicious DNS server to execute arbitrary code on the targeted system. Below you can find a brief technical explanation of all above mentioned critical and important vulnerabilities. Microsoft Office Memory Corruption Vulnerability (CVE-2017-11826) T...

Are you sure the WhatsApp app you are using on your Android device is legitimate, even if it's working perfectly as intended? ...Or the JioTV, AppLock, HotStar, Flipkart, Opera Mini or Truecaller app—if you have installed any of these? I'm asking this because cybersecurity researchers just yesterday revealed eye-opening details about a widespread Android malware campaign wherein attackers silently replaced installed legitimate apps with their malicious versions on nearly 25 million mobile phones. Now the important question here is how they're doing it and why? According to researchers at Check Point, attackers are distributing a new kind of Android malware that disguises itself as innocent-looking photo editing, adult entertainment, or gaming apps and available through widely used third-party app stores. Dubbed Agent Smith , the malware takes advantage of multiple Android vulnerabilities, such as the  Janus flaw and the Man-in-the-Disk flaw , and injects malic...

If you receive a link for a video, even if it looks exciting, sent by someone (or your friend) on Facebook messenger—just don't click on it without taking a second thought. Cybersecurity researchers from Trend Micro are warning users of a malicious Chrome extension which is spreading through Facebook Messenger and targeting users of cryptocurrency trading platforms to steal their accounts' credentials. Dubbed FacexWorm , the attack technique used by the malicious extension first emerged in August last year, but researchers noticed the malware re-packed a few new malicious capabilities earlier this month. New capabilities include stealing account credentials from websites, like Google and cryptocurrency sites, redirecting victims to cryptocurrency scams, injecting miners on the web page for mining cryptocurrency, and redirecting victims to the attacker's referral link for cryptocurrency-related referral programs. It is not the first malware to abuse Facebook Messenger...

Sandboxes are synonymous with dynamic malware analysis. They help to execute malicious files in a safe virtual environment and observe their behavior. However, they also offer plenty of value in terms of static analysis. See these five scenarios where a sandbox can prove to be a useful tool in your investigations. Detecting Threats in PDFs PDF files are frequently exploited by threat actors to deliver payloads. Static analysis in a sandbox makes it possible to expose any threat a malicious PDF contains by extracting its structure. The presence of JavaScript or Bash scripts can reveal a possible mechanism for downloading and executing malware.  Sandboxes like ANY.RUN also allows users to scrutinize URLs found in PDFs to identify suspicious domains, potential command and control (C2) servers, or other indicators of compromise. Example: Static analysis of a PDF file in ANY.RUN Interactivity allows our users to manipulate files within a VM as they wish, but static Discovery off...

Hackers have long used Word and Excel documents as delivery vehicles for malware, and in 2025, these tricks are far from outdated. From phishing schemes to zero-click exploits, malicious Office files are still one of the easiest ways into a victim's system. Here are the top three Microsoft Office-based exploits still making the rounds this year and what you need to know to avoid them. 1. Phishing in MS Office: Still Hackers' Favorite Phishing attacks using Microsoft Office files have been around for years, and they're still going strong. Why? Because they work, especially in business environments where teams constantly exchange Word and Excel documents. Attackers know that people are used to opening Office files, especially if they come from what looks like a colleague, a client, or a partner. A fake invoice, a shared report, or a job offer: it doesn't take much to convince someone to click. And once the file is open, the attacker has their chance. Phishing with Offic...
