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

Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or

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 - noblox.js-v

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

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

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 offers
