Researchers Uncover PyPI Package Hiding Malicious Code Behind Image File

Researchers Uncover PyPI Package Hiding Malicious Code Behind Image File

Nov 10, 2022
A malicious package discovered on the Python Package Index (PyPI) has been found employing a steganographic trick to conceal malicious code within image files. The package in question, named " apicolor ," was uploaded to the Python third-party repository on October 31, 2022, and described as a "Core lib for REST API," according to Israeli cybersecurity firm  Check Point . It has since been  taken down . Apicolor, like other  rogue packages  detected recently, harbors its malicious behavior in the setup script used to specify metadata associated with the package, such as its dependencies. This takes the form of a second package called "judyb" as well as a seemingly harmless PNG file ("8F4D2uF.png") hosted on Imgur, an image-sharing service. "The judyb code turned out to be a steganography module, responsible [for] hiding and revealing hidden messages inside pictures," Check Point explained. The attack chain entails using the judy

Zero-Day Flaws in Counter-Strike 1.6 Let Malicious Servers Hack Gamers' PCs

Mar 14, 2019
If you are a Counter-Strike gamer, then beware, because 39% of all existing Counter-Strike 1.6 game servers available online are malicious that have been set-up to remotely hack gamers' computers. A team of cybersecurity researchers at Dr. Web has disclosed that an attacker has been using malicious gaming servers to silently compromise computers of Counter-Strike gamers worldwide by exploiting zero-day vulnerabilities in the game client. According to the researchers, Counter-Strike 1.6, a popular game that's almost two decades old, contains unpatched multiple remote code execution (RCE) vulnerabilities in its client software that let attackers execute arbitrary code on the gamer's computer as soon as they connect to a malicious server, without requiring any further interaction from the gamers. It turned out that a Russian gaming server developer, nicknamed 'Belonard,' has been exploiting these vulnerabilities in the wild to promote his business and create a

Navigating the Threat Landscape: Understanding Exposure Management, Pentesting, Red Teaming and RBVM

Apr 29, 2024Exposure Management / Attack Surface
It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

Simple Exploit Allows Attackers to Modify Email Content — Even After It's Sent!

Simple Exploit Allows Attackers to Modify Email Content — Even After It's Sent!

Aug 23, 2017
Security researchers are warning of a new, easy-to-exploit email trick that could allow an attacker to turn a seemingly benign email into a malicious one after it has already been delivered to your email inbox. Dubbed Ropemaker (stands for Remotely Originated Post-delivery Email Manipulation Attacks Keeping Email Risky), the trick was uncovered by Francisco Ribeiro, the researcher at email and cloud security firm Mimecast. A successful exploitation of the Ropemaker attack could allow an attacker to remotely modify the content of an email sent by the attacker itself, for example swapping a URL with the malicious one. This can be done even after the email has already been delivered to the recipient and made it through all the necessary spam and security filters, without requiring direct access to the recipient's computer or email application, exposing hundreds of millions of desktop email client users to malicious attacks. Ropemaker abuses Cascading Style Sheets (CSS) and Hyp

WARNING — Malware Found in CamScanner Android App With 100+ Million Users

Aug 27, 2019
Beware! Attackers can remotely hijack your Android device and steal data stored on it, if you are using free version of  CamScanner , a highly-popular Phone PDF creator app with more than 100 million downloads on Google Play Store. So, to be safe, just uninstall the CamScanner app from your Android device now, as Google has already removed the app from its official Play Store. Unfortunately, CamScanner has recently gone rogue as researchers found a hidden Trojan Dropper module within the app that could allow remote attackers to secretly download and install malicious program on users' Android devices without their knowledge. However, the malicious module doesn't actually reside in the code of CamScanner Android app itself; instead, it is part of a 3rd-party advertising library that recently was introduced in the PDF creator app. Discovered by Kaspersky security researchers, the issue came to light after many CamScanner users spotted suspicious behavior and posted neg

A Bug Could Let Attackers Hijack Firefox for Android via Wi-Fi Network

Sep 19, 2020
Dear Android users, if you use the Firefox web browser on your smartphones, make sure it has been updated to version 80 or the latest available version on the Google Play Store. ESET security researcher Lukas Stefanko yesterday tweeted an alert demonstrating the exploitation of a recently disclosed high-risk remote command execution vulnerability affecting the Firefox app for Android. Discovered originally by Australian security researcher Chris Moberly , the vulnerability resides in the SSDP engine of the browser that can be exploited by an attacker to target Android smartphones connected to the same Wi-Fi network as the attacker, with Firefox app installed. SSDP, stands for Simple Service Discovery Protocol, is a UDP based protocol that is a part of UPnP for finding other devices on a network. In Android, Firefox periodically sends out SSDP discovery messages to other devices connected to the same network, looking for second-screen devices to cast. Any device on the local netwo

Scammers have again targeted more than one billion active users of the popular social networking giant Facebook, to infect as many victims as possible. Not by serving fake post, neither by providing malicious video link, instead this time scammers have used a new way of tricking Facebook users into injecting or placing malicious JavaScript or client-side code into their web browsers. This malicious code could allow an attacker to gain access to victims' accounts, thereby using it for fraud, to send spams, and promoting further attacks by posting the scam on timeline to victims' friends. This technique is known as Self Cross-site Scripting or Self XSS. Self-XSS (Self Cross-Site Scripting) scam is a combination of social engineering and a browser vulnerability , basically designed to trick Facebook users' into providing access to their account. Once an attacker or scammer gets access to users' Facebook account, they can even post and comment on things on users' behalf.

APT Hackers Turn to Malicious Excel Add-ins as Initial Intrusion Vector

APT Hackers Turn to Malicious Excel Add-ins as Initial Intrusion Vector

Dec 28, 2022 Malware / Windows Security
Microsoft's decision to block Visual Basic for Applications (VBA) macros by default for Office files downloaded from the internet has led many threat actors to improvise their attack chains in recent months. Now according to Cisco Talos , advanced persistent threat (APT) actors and commodity malware families alike are increasingly using Excel add-in (.XLL) files as an initial intrusion vector. Weaponized Office documents delivered via spear-phishing emails and other social engineering attacks have remained one of the widely used entry points for criminal groups looking to execute malicious code. These documents traditionally prompt the victims to enable macros to view seemingly innocuous content, only to activate the execution of malware stealthily in the background. To counter this misuse, the Windows maker enacted a crucial change starting in July 2022 that blocks macros in Office files attached to email messages, effectively severing a crucial attack vector. While this

Hackers Abusing GitHub to Evade Detection and Control Compromised Hosts

Dec 19, 2023 Software Security / Threat intelligence
Threat actors are increasingly making use of GitHub for malicious purposes through novel methods, including abusing secret Gists and issuing malicious commands via git commit messages. "Malware authors occasionally place their samples in services like Dropbox, Google Drive, OneDrive, and Discord to host second stage malware and sidestep detection tools," ReversingLabs researcher Karlo Zanki  said  in a report shared with The Hacker News. "But lately, we have observed the increasing use of the GitHub open-source development platform for hosting malware." Legitimate public services are  known  to be  used  by  threat actors  for hosting malware and acting as  dead drop resolvers  to fetch the actual command-and-control (C2) address. While using public sources for C2 does not make them immune to takedowns, they do offer the benefit of allowing threat actors to easily create attack infrastructure that's both inexpensive and reliable. This technique is sneaky

Oct 12, 2023 Software Security / Malware
A malicious package hosted on the NuGet package manager for the .NET Framework has been found to deliver a remote access trojan called SeroXen RAT. The package, named Pathoschild.Stardew.Mod.Build.Config and published by a user named  Disti , is a typosquat of a legitimate package called  Pathoschild.Stardew.ModBuildConfig , software supply chain security firm Phylum  said  in a report today. While the real package has received nearly 79,000 downloads to date, the malicious variant is said to have artificially inflated its download count after being published on October 6, 2023, to surpass 100,000 downloads. The profile behind the package has published six other packages that have attracted no less than 2.1 million downloads cumulatively, four of which masquerade as libraries for various crypto services like Kraken, KuCoin, Solana, and Monero, but are also designed to deploy SeroXen RAT. The attack chain is initiated during installation of the package by means of a tools/init.ps1
