January 09, 2019Swati Khandelwal
Google has removed 85 apps from its Play Store after finding out that they were pushing aggressive, full-screen adware to Android users. With the rise in the mobile market, Adware has become one of the most prevalent mobile threats in the world. Adware has traditionally been used to aggressively push ads like banners or pop-ups on mobile screens to make money for its makers. The now-removed 85 apps in question disguised as games, streaming TV, and remote control simulator apps in the Google Play store and had collectively been installed by nine million users all over the world. Researchers from cyber security company Trend Micro spotted these apps which has the ability to bombard user devices with full-screen advertisements at regular intervals or when users unlock their device by monitoring their screen unlocking functionality. The apps can display ads even when you are not browsing the internet, hide themselves and run in the background on infected devices. The most popul

Thousands of Mobile Apps Expose Their Unprotected Firebase Hosted Databases

June 21, 2018Mohit Kumar
Mobile security researchers have discovered unprotected Firebase databases of thousands of iOS and Android mobile applications that are exposing over 100 million data records, including plain text passwords, user IDs, location, and in some cases, financial records such as banking and cryptocurrency transactions. Google’s Firebase service is one of the most popular back-end development platforms for mobile and web applications that offers developers a cloud-based database, which stores data in JSON format and synced it in the real-time with all connected clients. Researchers from mobile security firm Appthority discovered that many app developers' fail to properly secure their back-end Firebase endpoints with firewalls and authentication, leaving hundreds of gigabytes of sensitive data of their customers publicly accessible to anyone. Since Firebase offers app developers an API server, as shown below, to access their databases hosted with the service, attackers can gain acce

In the digital age, one of the most popular sayings is—if you're not paying, then you're not the customer, you're the product. While downloading apps on their smartphones, most users may not realize how much data they collect on you. Believe me; it’s way more than you can imagine. Nowadays, many app developers are following irresponsible practices that are worth understanding, and we don't have a better example than this newly-reported incident about a virtual keyboard app. A team of security researchers at the Kromtech Security Center has discovered a massive trove of personal data belonging to more than 31 million users of the popular virtual keyboard app, AI.type, accidentally leaked online for anyone to download without requiring any password. Founded in 2010, Ai.type is a customizable and personalizable on-screen keyboard for mobile phones and tablets, with more than 40 million users worldwide. Apparently, a misconfigured MongoDB database, owned by
Warning — Popular 'Hot Patching' Technique Puts iOS Users At Risk

Warning — Popular 'Hot Patching' Technique Puts iOS Users At Risk

February 01, 2016Swati Khandelwal
Do you know?… Any iOS app downloaded from Apple’s official App Store has an ability to update itself from any 3rd-party server automatically without your knowledge. Yes, it is possible, and you could end up downloading malware on your iPhone or iPad. Unlike Google, Apple has made remarkable efforts to create and maintain a healthy and clean ecosystem of its official App Store. Although Apple's review process and standards for security and integrity are intended to protect iOS users, developers found the process time consuming and extremely frustrating while issuing a patch for a severe bug or security flaw impacting existing app users. To overcome this problem, Apple designed a set of solutions to make it easier for iOS app developers to push straightway out hotfixes and updates to app users without going through Apple's review process. Sounds great, but here's the Kick: Malicious app developers can abuse These solutions, potentially allowing th

SandroRAT — Android Malware that Disguises itself as "Kaspersky Mobile Security" App

August 05, 2014Mohit Kumar
Researchers have warned users of Android devices to avoid app downloads from particularly unauthorized sources, since a new and sophisticated piece of malware is targeting Android users through phishing emails . The malware, dubbed SandroRAT , is currently being used by cybercriminals to target Android users in Poland via a widely spread email spam campaign that delivers a new variant of an Android remote access tool (RAT). The emails masquerade itself as a bank alert that warns users of the malware infection in their mobile device and offers a fake mobile security solution in order to get rid of the malware infection. The mobile security solution poses as a Kaspersky Mobile Security , but in real, it is a version of SandroRAT, a remote access tool devised for Android devices, whose source code has been put on sale on underground Hack Forums since December last year. A mobile malware researcher at McAfee, Carlos Castillo, detailed the new variant of Android remot

If a whistleblower discloses an activity to the public, then there should be a trust-based mechanism that ensure the protection of truth-tellers on an international level by hiding their identities. In an effort to provide this kind of service and security, Security experts grouped together to create a stealthy Internet Messenger (IM) and file transfer client, which is especially designed for whistleblowers. Dubbed as “ ‪invisible.im ” is an anonymous Instant Messenger (IM) that leaves no trace‬. The team behind the project called itself “ The Infosec A-Team ” which includes Metasploit Founder HD Moore , noted infosec and opsec experts The Grugq , an Australian security analyst Patrick Gray , and Richo . Invisible.im aims to serve the rigid anonymity needs of whistleblowers. The project website states: invisible.im was established to develop an instant messenger and file transfer tool that leaves virtually no evidence of conversations or transfers having occurred. Th

Beware! Hackers can cause Traffic jams with just a navigation Smartphone application. Two Israeli students were assigned by college to hack Google-owned Waze GPS app , an Israeli-made Smartphone app that provides directions and alerts drivers to traffic and accidents. Shir Yadid and Meital Ben-Sinai , fourth-year students at Technion-Israel Institute of Technology, with the help of two advisers created a virtual program that successfully caused the popular navigation application Waze to report fake traffic jams,  Haaretz  reported. They successfully launched a demo cyber attack against the popular navigation app, with no evil intention to cause any damage to the app, instead it was a simple assignment handed over to these students to demonstrate up to what a malicious hacker could do by creating a fake traffic jam on any popular app, like Waze that provides real-time traffic updates and notifications to users on the road. HOW TO JAM TRAFFIC? To carry out their proje

LinkedIn shutting down its security-plagued INTRO app in Early March

Last October, the social network ' LinkedIn ' launched a controversial Smartphone app called ' Intro ' that intercepts and route all of your emails through LinkedIn servers to inject LinkedIn profiles of the sender directly into the mails. The app was released for Android , as well as iOS devices. Why Controversial? The app puts the security and privacy of your data entirely in the company’s hands, and at that time everyone criticized and reacted negatively, but LinkedIn defended Intro, claiming that all information was fully encrypted and deleted from LinkedIn’s servers immediately. Just two days back, I got an e-mail from LinkedIn with the subject line “ We’re retiring LinkedIn Intro. ” i.e. LinkedIn is giving up so quickly just four months of the launch! In a blog post today, LinkedIn SVP of products Deep Mishar explained, " We are shutting down LinkedIn Intro as of March 7, 2014. The intro was launched last year to bring the power of LinkedIn to your emai

In the last quarter of 2013, sale of a Smartphone with ANDROID operating system has increased and every second person you see is a DROID user. A Russian security firm ' Doctor Web' identified the first mass distributed Android bootkit malware called ' Android.Oldboot ', a piece of malware that's designed to re-infect devices after reboot, even if you delete all working components of it. The bootkit Android.Oldboot has infected more than 350,000 android users in China, Spain, Italy, Germany, Russia, Brazil, the USA and some Southeast Asian countries. China seems to a mass victim of this kind of malware having a 92 % share. A Bootkit is a rootkit malware variant which infects the device at start-up and may encrypt disk or steal data, remove the application, open connection for Command and controller. A very unique technique is being used to inject this Trojan into an Android system where an attacker places a component of it into the boot

January 28, 2014Unknown
A location based Social Networking platform with 45 million users,' Foursquare ' was vulnerable to the primary email address disclosed.  Foursquare is a Smartphone application that gives you details of nearby cafes, bars, shops, parks using GPS location and also tells about your friends nearby. According to a Penetration tester and hacker ' Jamal Eddin e ',  an attacker can extract email addresses of all 45 million users just by using a few lines of scripting tool. Basically the flaw exists in the Invitation system of the Foursquare app. While testing the app, he found that invitation received on the recipient's end actually disclosing the sender's email address, as shown above. Invitation URL:  https://foursquare.com/mehdi?action=acceptFriendship&expires=1378920415&src=wtbfe& uid = 64761059 &sig=mmlx96RwGrQ2fJAg4OWZhAWnDvc%3D Where 'uid' parameter represents the sender's profile ID.  Hacker noticed th
