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 offers

If you have visited any popular mainstream website over the past two months, your computer may have been infected — Thanks to a new exploit kit discovered by security researchers. Researchers from antivirus provider ESET released a report on Tuesday stating that they have discovered an exploit kit, dubbed Stegano , hiding malicious code in the pixels of banner advertisements that are currently in rotation on several high profile news websites. Stegano originally dates back to 2014, but since early October this year, cyber crooks had managed to get the malicious ads displayed on a variety of unnamed reputable news websites, each with Millions of daily visitors. Stegano derived from the word Steganography , which is a technique of hiding messages and content inside a digital graphic image, making the content impossible to spot with the naked eye. In this particular malvertising campaign, operators hide malicious code inside transparent PNG image's Alpha Channel, which def

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

Do you know how many kinds of sensors your smartphone has inbuilt? And what data they gather about your physical and digital activities? An average smartphone these days is packed with a wide array of sensors such as GPS, Camera, microphone, accelerometer, magnetometer, proximity, gyroscope, pedometer, and NFC, to name a few. Now, according to a team of scientists from Newcastle University in the UK, hackers can potentially guess PINs and passwords – that you enter either on a bank website, app, your lock screen – to a surprising degree of accuracy by monitoring your phone's sensors, like the angle and motion of your phone while you are typing. The danger comes due to the way malicious websites and apps access most of a smartphone's internal sensors without requesting any permission to access them – doesn't matter even if you are accessing a secure website over HTTPS to enter your password. Your Phone doesn't Restrict Apps from Accessing Sensors' Data

Due to the majority in the mobile platform, Google's Android operating system has been a prior target for cybercriminals and a recently exposed weakness in the way the operating system handles certificate validation, left millions of Android devices open to attack. Researchers at BlueBox security , who identified the vulnerability, dubbed the flaw as Fake ID , which affects all versions of Android operating system from 2.1 ( released in 2010 ) up to Android 4.4, also known as KitKat . ALL VERSIONS ARE VULNERABLE UPTO KITKAT Researchers marked the vulnerability as critical because it could allow a fake and malicious app to masquerade as a legitimate and trusted application, enabling an attacker to perform various actions such as inserting malicious code into a legitimate app, infiltrating your personal information or even take complete control of an affected device. Specifically, devices running the 3LM administration extension are at risk for a complete compromise, whic

India-linked highly targeted mobile malware campaign, first unveiled two weeks ago , has been found to be part of a broader campaign targeting multiple platforms, including windows devices and possibly Android as well. As reported in our previous article , earlier this month researchers at Talos threat intelligence unit discovered a group of Indian hackers abusing mobile device management (MDM) service to hijack and spy on a few targeted iPhone users in India. Operating since August 2015, the attackers have been found abusing MDM service to remotely install malicious versions of legitimate apps, including Telegram, WhatsApp, and PrayTime, onto targeted iPhones. These modified apps have been designed to secretly spy on iOS users, and steal their real-time location, SMS, contacts, photos and private messages from third-party chatting applications. During their ongoing investigation, Talos researchers identified a new MDM infrastructure and several malicious binaries – designed

The North Korea-linked threat actor known as Moonstone Sleet has continued to push malicious npm packages to the JavaScript package registry with the aim of infecting Windows systems, underscoring the persistent nature of their campaigns. The packages in question, harthat-api and harthat-hash , were published on July 7, 2024, according to Datadog Security Labs. Both the libraries did not attract any downloads and were shortly pulled after a brief period of time. The security arm of the cloud monitoring firm is tracking the threat actor under the name Stressed Pungsan, which exhibits overlaps with a newly discovered North Korean malicious activity cluster dubbed Moonstone Sleet. "While the name resembles the Hardhat npm package (an Ethereum development utility), its content does not indicate any intention to typosquat it," Datadog researchers Sebastian Obregoso and Zack Allen said . "The malicious package reuses code from a well-known GitHub repository called node-

Security researchers have been warning of a new trick that cybercriminals are leveraging to hide their malicious code designed to re-introduce the infection to steal confidential information from Magento based online e-commerce websites. So, if you have already cleaned up your hacked Magento website, there are chances your website is still leaking login credentials and credit card details of your customers to hackers. More than 250,000 online stores use open-source Magento e-commerce platform, which makes them an enticing target for hackers, and therefore the security of both your data and your customer data is of the utmost importance. According to the researchers at Sucuri , who have previously spotted several Magento malware campaigns in the wild, cybercriminals are currently using a simple yet effective method to ensure that their malicious code is added back to a hacked website after it has been removed. To achieve this, criminals are hiding their 'credit card stea

So you love Minecraft ? You might want to be very careful before downloading the cheats for the popular Minecraft game from Google Play Store. Nearly 3 Million users have downloaded malicious Minecraft Android applications for their smartphone and tablets from the Google Play store, security researchers warned. The security researchers from IT security firm ESET have uncovered as many as 33 fake "scareware" applications that have been uploaded to the Google Play store in the course of the past 9 months, masquerading as Minecraft cheats and tip guides. These malicious applications have been downloaded between 660,000 and 2.8 million times. "All of the discovered apps were fake in that they did not contain any of the promised functionality and only displayed banners that tried to trick users into believing that their Android system is infected with a dangerous virus," ESET researcher Lukas Stefanko wrote in a blog post . Once downloaded, these mali

Yet another incident which showcases that you should not explicitly trust user-controlled software repositories. One of the most popular Linux distros Arch Linux has pulled as many as three user-maintained software repository AUR packages after it was found hosting malicious code. Arch Linux is an independently developed, general-purpose GNU/Linux distribution composed predominantly of free and open-source software, and supports community involvement. Besides official repositories like Arch Build System (ABS), Arch Linux users can also download software packages from several other repositories, including AUR (Arch User Repository), a community-driven repository created and managed by Arch Linux users. Since AUR packages are user-produced content, Arch maintainers always suggest Linux users to carefully check all files, especially PKGBUILD and any .install file for malicious commands. However, this AUR repository has recently been found hosting malware code in several inst

A widely used third-party NodeJS module with nearly 2 million downloads a week was compromised after one of its open-source contributor gone rogue, who infected it with a malicious code that was programmed to steal funds stored in Bitcoin wallet apps. The Node.js library in question is "Event-Stream," a toolkit that makes it easy for developers to create and work with streams, a collection of data in Node.js — just like arrays or strings. The malicious code detected earlier this week was added to Event-Stream version 3.3.6, published on September 9 via NPM repository , and had since been downloaded by nearly 8 million application programmers. Event-Stream module for Node.js was originally created by Dominic Tarr, who maintained the Event-Stream library for a long time, but handed over the development and maintenance of the project several months ago to an unknown programmer, called "right9ctrl." Apparently, right9ctrl gained Dominic's trust by making

Android -  a widely used Smartphone platform offered by Google is once again suspected to affect its users with malicious software that puts their android devices at risk. This time the vulnerabilities occur in the way Android handle the updates to add new flavors to your device. Researchers from Indiana University and Microsoft have discovered [ Paper PDF ] a new set of Android vulnerabilities that is capable to carry out privilege escalation attacks because of the weakness in its Package Management Service (PMS) that puts more than one billion Android devices at risk. The researchers dubbed the new set of security-critical vulnerabilities as Pileup flaws which is a short for privilege escalation through updating, that waylays inside the Android PMS and intensifies the permissions offered to malicious apps whenever an android update occurs, without informing users. The research was carried out by Indiana University Bloomington researchers, Luyi Xing, Xiaorui Pan, Ka

Last year, the popular system cleanup software CCleaner suffered a massive supply-chain malware attack of all times, wherein hackers compromised the company's servers for more than a month and replaced the original version of the software with the malicious one. The malware attack infected over 2.3 million users who downloaded or updated their CCleaner app between August and September last year from the official website with the backdoored version of the software. Now, it turns out that the hackers managed to infiltrate the company's network almost five months before they first replaced the official CCleaner build with the backdoored version, revealed Avast executive VP and CTO Ondrej Vlcek at the RSA security conference in San Francisco on Tuesday. 6-Months Timeline of CCleaner Supply Chain Attack Vlcek shared a brief timeline of the last year's incident that came out to be the worst nightmare for the company, detailing how and when unknown hackers breached Pi

Google Android has been a primary concern of the attackers. Counting from a simple text message that could hack an Android phone remotely to the Stagefright bug making Billion users vulnerable. Now, the latest is the ' Kemoge Malware ' that has made its debut as an Adware on the Android mobile phones, allowing third-party app stores to fetch your device's information and take full control of it. Security researchers from FireEye Labs have discovered that Kemoge malicious adware family is spreading in 20 countries around the globe. Also, the origin of the Adware's attack is suspected from China. What is Kemoge? The name given to the malicious Adware family is because of its command and control (C2) domain: aps.kemoge.net. Kemoge is an Adware in the disguise of popular Apps; it has circulated in such numbers because it takes the name of popular apps and repackages them with the malicious code and make them available to the user. They even use

Google has made several new announcements for its Chrome Web Store that aims at making Chrome extensions more secure and transparent to its users. Over a couple of years, we have seen a significant rise in malicious extensions that appear to offer useful functionalities, while running hidden malicious scripts in the background without the user's knowledge. However, the best part is that Google is aware of the issues and has proactively been working to change the way its Chrome web browser handles extensions. Earlier this year, Google banned extensions using cryptocurrency mining scripts and then in June, the company also disabled inline installation of Chrome extensions completely. The company has also been using machine learning technologies to detect and block malicious extensions. To take a step further, Google announced Monday five major changes that give users more control over certain permissions, enforces security measures, as well as makes the ecosystem more t
