Cybersecurity researchers have uncovered two malicious machine learning (ML) models on Hugging Face that leveraged an unusual technique of "broken" pickle files to evade detection. "The pickle files extracted from the mentioned PyTorch archives revealed the malicious Python content at the beginning of the file," ReversingLabs researcher Karlo Zanki said in a report shared with The Hacker News. "In both cases, the malicious payload was a typical platform-aware reverse shell that connects to a hard-coded IP address." The approach has been dubbed nullifAI, as it involves clearcut attempts to sidestep existing safeguards put in place to identify malicious models. The Hugging Face repositories have been listed below - glockr1/ballr7 who-r-u0000/0000000000000000000000000000000000000 It's believed that the models are more of a proof-of-concept (PoC) than an active supply chain attack scenario. The pickle serialization format, used commonly for dis...

Next time when someone sends you a photo of a cute cat or a hot chick than be careful before you click on the image to view — it might hack your machine. Yes, the normal looking images could hack your computers — thanks to a technique discovered by security researcher Saumil Shah from India. Dubbed " Stegosploit ," the technique lets hackers hide malicious code inside the pixels of an image, hiding a malware exploit in plain sight to infect target victims. Just look at the image and you are HACKED! Shah demonstrated the technique during a talk titled , " Stegosploit: Hacking With Pictures, " he gave on Thursday at the Amsterdam hacking conference Hack In The Box. According to Shah, "a good exploit is one that is delivered in style." Keeping this in mind, Shah discovered a way to hide malicious code directly into an image, rather than hiding it in email attachments, PDFs or other types of files that are typically used to deliver...

A security weakness has been disclosed in the artificial intelligence (AI)-powered code editor Cursor that could trigger code execution when a maliciously crafted repository is opened using the program. The issue stems from the fact that an out-of-the-box security setting is disabled by default, opening the door for attackers to run arbitrary code on users' computers with their privileges. "Cursor ships with Workspace Trust disabled by default, so VS Code-style tasks configured with runOptions.runOn: 'folderOpen' auto-execute the moment a developer browses a project," Oasis Security said in an analysis. "A malicious .vscode/tasks.json turns a casual 'open folder' into silent code execution in the user's context." Cursor is an AI-powered fork of Visual Studio Code, which supports a feature called Workspace Trust to allow developers to safely browse and edit code regardless of where it came from or who wrote it. With this option disab...

Cyber attackers never stop inventing new ways to compromise their targets. That's why organizations must stay updated on the latest threats.  Here's a quick rundown of the current malware and phishing attacks you need to know about to safeguard your infrastructure before they reach you. Zero-day Attack: Corrupted Malicious Files Evade Detection by Most Security Systems  The analyst team at ANY.RUN recently shared their analysis of an ongoing zero-day attack . It has been active since at least August and still remains unaddressed by most detection software to this day. The attack involves the use of intentionally corrupted Word documents and ZIP archives with malicious files inside. VirusTotal shows 0 detections for one of the corrupted files Due to corruption, security systems cannot properly identify the type of these files and run analysis on them, which results in zero threat detections. Word will ask the user if they want to restore a corrupted file Once these fi...

Chinese-speaking users have been targeted by malicious Google ads for restricted messaging apps like Telegram as part of an ongoing malvertising campaign. "The threat actor is abusing Google advertiser accounts to create malicious ads and pointing them to pages where unsuspecting users will download Remote Administration Trojan (RATs) instead," Malwarebytes' Jérôme Segura  said  in a Thursday report. "Such programs give an attacker full control of a victim's machine and the ability to drop additional malware." It's worth noting that the activity, codenamed  FakeAPP , is a continuation of a  prior attack wave  that targeted Hong Kong users searching for messaging apps like WhatsApp and Telegram on search engines in late October 2023. The latest iteration of the campaign also adds messaging app LINE to the list of messaging apps, redirecting users to bogus websites hosted on Google Docs or Google Sites. The Google infrastructure is used to embed link...

Late last week an unknown hacker or a group of hackers successfully targeted a cryptocurrency exchange with an aim to steal Bitcoins by compromising the web analytics service it was using. ESET malware researcher Matthieu Faou this weekend spotted malicious JavaScript code on up to 700,000 websites that were bundled with the traffic tracking code from the leading web analytics platform StatCounter . However, after analyzing the code, the researchers found that hackers managed to compromise StatCounter and successfully replaced its tracking script with malicious JavaScript code primarily designed to target customers of the Gate.io cryptocurrency exchange. Like Google Analytics, StatCounter is also an old, but popular real-time web analytics platform reportedly being used by more than two million websites and generates stats on over 10 billion page views per month. Here's How Hackers Tried to Steal Bitcoins from Crypto Exchange Though the malicious code was also inject...

Cybercriminals have rolled out a new malicious Android application that wraps different varieties of banking fraud trick into a single piece of advanced mobile malware . GOOGLE SERVICE FRAMEWORK - APPLICATION OR MALWARE? Security researchers at the security firm FireEye have came across a malicious Android application that binds together the latest and older hijacking techniques. The malicious Android app combines private data theft, banking credential theft and spoofing, and remote access into a single unit, where traditional malware has had only one such capability included in it. Researchers dubbed the malware as HijackRAT , a banking trojan that comes loaded with a malicious Android application which disguises itself as "Google Service Framework," first and the most advanced Android malware sample of its kind ever discovered, combining all the three malicious activities together. MALWARE FEATURES By giving the remote control of the infected device to hackers,...

The maintainers of the Python Package Index (PyPI) repository briefly suspended new user sign-ups following an influx of malicious projects uploaded as part of a typosquatting campaign. PyPI said "new project creation and new user registration" was temporarily halted to mitigate what it said was a "malware upload campaign." The incident was resolved 10 hours later, on March 28, 2024, at 12:56 p.m. UTC. Software supply chain security firm Checkmarx said the unidentified threat actors behind flooding the repository targeted developers with typosquatted versions of popular packages. "This is a multi-stage attack and the malicious payload aimed to steal crypto wallets, sensitive data from browsers (cookies, extensions data, etc.), and various credentials," researchers Yehuda Gelb, Jossef Harush Kadouri, and Tzachi Zornstain  said . "In addition, the malicious payload employed a persistence mechanism to survive reboots." The findings were also c...

Apple Mac Computers are considered to be invulnerable to malware, but the new Exploit discovered by security researchers proves it indeed quite false. Patrick Wardle , director of research at security firm Synack , has found a deadly simple way that completely bypass one of the core security features in Mac OS X i.e.  Gatekeeper . Introduced in July of 2012, Gatekeeper is Apple's anti-malware feature designed to keep untrusted and malicious applications from wreaking havoc on Macs. However, Wardle has found a quick and simple way to trick Gatekeeper into letting malicious apps through on Mac OS X machines, even if the protection is set to open apps downloaded only from the Mac App Store. According to the researcher, before allowing any apps to execute on an OS X machine, Gatekeeper performs a number of checks, such as: Checking the initial digital certificate of a downloaded app Ensuring the app has been signed with an Apple-recognized developer certificat...

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...
