An alarming security vulnerability has been discovered in several models of Android smartphones manufactured by Google, Samsung, and others that could allow malicious apps to secretly take pictures and record videos — even when they don't have specific device permissions to do so. You must already know that the security model of the Android mobile operating system is primarily based on device permissions where each app needs to explicitly define which services, device capabilities, or user information it wants to access. However, researchers at Checkmarx discovered that a vulnerability, tracked as CVE-2019-2234 , in pre-installed camera apps on millions of devices could be leveraged by attackers to bypass such restrictions and access device camera and microphone without any permissions to do so. How Can Attackers Exploit the Camera App Vulnerability? The attack scenario involves a rogue app that only needs access to device storage (i.e., SD card), which is one of the mo...

A large number of third-party Android apps have reportedly been discovered grabbing copies of all text messages received or sent to infected devices and sending them to the attackers' server. More than 63,000 Android applications use Taomike SDK – one of the biggest mobile advertisement solutions in China – to help developers display ads in their mobile apps and generate revenue. However, around 18,000 of these Android apps contains a malicious code that spy on users text messages, according to researchers at Palo Alto Networks, who made the discovery . Taomike provides a Software Development Toolkit (SDK) and services to the Android app developers using which they can: Displaying advertisements to users Offer in-app purchases (IAPs) Android Apps Stealing SMS Messages Focussing on distributing the app and techniques for building revenue, "Not all apps that use the Taomike library steal SMS messages," security researchers said. The security...

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 ...

Watch out! If you have any of the below-mentioned file managers and photography apps installed on your Android phone—even if downloaded from the official Google Store store⁠—you have been hacked and being tracked. These newly detected malicious Android apps are Camero , FileCrypt , and callCam that are believed to be linked to Sidewinder APT, a sophisticated hacking group specialized in cyber espionage attacks. According to cybersecurity researchers at Trend Micro, these apps were exploiting a critical use-after-free vulnerability in Android at least since March last year⁠—that's 7 months before the same flaw was first discovered as zero-day when Google researcher analysed a separate attack developed by Israeli surveillance vendor NSO Group. "We speculate that these apps have been active since March 2019 based on the certificate information on one of the apps," the researchers said . Tracked as CVE-2019-2215 , the vulnerability is a local privilege escalation...

Yesterday WikiLeaks published thousands of documents revealing top CIA hacking secrets , including the agency's ability to break into iPhones, Android phones, smart TVs, and Microsoft, Mac and Linux operating systems. It dubbed the first release as Vault 7 . Vault 7 is just the first part of leak series " Year Zero " that WikiLeaks will be releasing in coming days. Vault 7 is all about a covert global hacking operation being run by the US Central Intelligence Agency (CIA). According to the whistleblower organization, the CIA did not inform the companies about the security issues of their products; instead held on to security bugs in software and devices, including iPhones, Android phones, and Samsung TVs, that millions of people around the world rely on. One leaked document suggested that the CIA was even looking for tools to remotely control smart cars and trucks, allowing the agency to cause "accidents" which would effectively be "nearly undetectable assas...

Own an Android smartphone? Hackers can secretly install malicious apps, games, and pop-up adverts on your smartphone remotely in order to make large sums of money. Security researchers at Cheetah Mobile have uncovered one of the world's largest and most prolific Trojan families, infecting millions of Android devices around the world. Dubbed Hummer , the notorious mobile trojan stealthily installs malicious apps, games, or even porn apps onto victim's phones and yields its creators more than $500,000 (£375,252) on a daily basis. First discovered in 2014 by Cheetah Mobile, Hummer gained traction in early 2016 when the Trojan family was infecting "nearly 1.4 Million devices daily at its peak" with 63,000 infections occurring daily in China, according to researchers at Cheetah Mobile Security Research Lab. "This Trojan continually pops up ads on victims' phones, which is extremely annoying," researchers wrote in a blog post. "It also pushe...

A hacking group known for its attacks in the Middle East, at least since 2017, has recently been found impersonating legitimate messaging apps such as Telegram and Threema to infect Android devices with a new, previously undocumented malware. "Compared to the versions documented in 2017, Android/SpyC23.A has extended spying functionality, including reading notifications from messaging apps, call recording and screen recording, and new stealth features, such as dismissing notifications from built-in Android security apps," cybersecurity firm ESET  said  in a Wednesday analysis. First detailed by Qihoo 360 in 2017 under the moniker  Two-tailed Scorpion (aka APT-C-23 or Desert Falcon), the mobile malware has been deemed "surveillanceware" for its abilities to spy on the devices of targeted individuals, exfiltrating call logs, contacts, location, messages, photos, and other sensitive documents in the process. In 2018, Symantec discovered a  newer variant  of t...

We know that Hackers hack for a variety of reasons: ...some hack to test their skills, …some hack to gain recognition, ...some hack to make money, ...some hack to support their Nation-State strategy, ...and, some hack alone, and some hack in Groups. And Chinese Hackers are the ones who are infamous for their dedication towards Hacking. Chinese hacking groups are better known for attacking and stealing information, organized cyber crimes, theft of intellectual property and state-sponsored cyber espionage attacks. But it seems that several Chinese hacker groups have now shifted their motive of hacking towards ' making money '. How much Money Hackers Actually Make? It is a known fact that hacking makes money, but how much? Answer: At least $4,500,000/year   from one malware campaign. How? We often observe mobile and desktop applications bundled with Ad-displaying programs, called Adware, to generate revenue. Just last week we repo...

In Brief The famous '60 Minutes' television show shocked some viewers Sunday evening when a team of German hackers demonstrated how they spied on an iPhone used by U.S. Congressman, then recorded his phone calls and tracked his movement through Los Angeles. Hackers leverage a security flaw in SS7 (Signalling System Seven) protocol that allows hackers to track phone locations, listen in on calls and text messages. The global telecom network SS7 is still vulnerable to several security flaws that could let hackers and spy agencies listen to personal phone calls and intercept SMSes on a potentially massive scale, despite the most advanced encryption used by cellular networks. All one need is the target's phone number to track him/her anywhere on the planet and even eavesdrop on the conversations. SS7 or Signalling System Number 7 is a telephony signaling protocol used by more than 800 telecommunication operators around the world to exchange information with one ...

Just because an app is available on Google Play Store doesn't mean that it is a legitimate app. Despite so many efforts by Google, some fake and malicious apps do sneak in and land millions of unaware users on the hunting ground of scammers and hackers. Cybersecurity firm Trend Micro uncovered at least 29 devious photo apps that managed to make its way onto Google Play Store and have been downloaded more than 4 million times before Google removed them from its app store. The mobile apps in question disguised as photo editing and beauty apps purporting to use your mobile phone's camera to take better pictures or beautify the snaps you shoot, but were found including code that performs malicious activities on their users' smartphone. Three of the rogue apps—Pro Camera Beauty, Cartoon Art Photo and Emoji Camera—have been downloaded more than a million times each, with Artistic Effect Filter being installed over 500,000 times and another seven apps in the list over 100...

Bought a new Android phone? What if I say your brand new smartphone can be hacked remotely? Nearly all Android phones come with useless applications pre-installed by manufacturers or carriers, usually called bloatware, and there's nothing you can do if any of them has a backdoor built-in—even if you're careful about avoiding sketchy apps. That's exactly what security researchers from mobile security firm Kryptowire demonstrated at the DEF CON security conference on Friday. Researchers disclosed details of 47 different vulnerabilities deep inside the firmware and default apps (pre-installed and mostly non-removable) of 25 Android handsets that could allow hackers to spy on users and factory reset their devices, putting millions of Android devices at risk of hacking. At least 11 of those vulnerable smartphones are manufactured by companies including Asus, ZTE, LG, and the Essential Phone, and being distributed by US carriers like Verizon and AT&T. Other majo...

Some of the biggest security problems start quietly. No alerts. No warnings. Just small actions that seem normal but aren't. Attackers now know how to stay hidden by blending in, and that makes it hard to tell when something's wrong. This week's stories aren't just about what was attacked—but how easily it happened. If we're only looking for the obvious signs, what are we missing right in front of us? Here's a look at the tactics and mistakes that show how much can go unnoticed. ⚡ Threat of the Week Apple Zero-Click Flaw in Messages Exploited to Deliver Paragon Spyware — Apple disclosed that a security flaw in its Messages app was actively exploited in the wild to target civil society members in sophisticated cyber attacks. The vulnerability, CVE-2025-43200, was addressed by the company in February as part of iOS 18.3.1, iPadOS 18.3.1, iPadOS 17.7.5, macOS Sequoia 15.3.1, macOS Sonoma 14.7.4, macOS Ventura 13.7.4, watchOS 11.3.1, and visionOS 2.3.1.

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...

A cybercrime enterprise known as  Lemon Group  is leveraging millions of pre-infected Android smartphones worldwide to carry out their malicious operations, posing significant supply chain risks. "The infection turns these devices into mobile proxies, tools for stealing and selling SMS messages, social media and online messaging accounts and monetization via advertisements and click fraud," cybersecurity firm Trend Micro  said . The activity encompasses no fewer than 8.9 million compromised Android devices, particularly budget phones, with the highest concentration of the infections discovered in the U.S., Mexico, Indonesia, Thailand, Russia, South Africa, India, Angola, the Philippines, and Argentina. The findings were  presented  by researchers Fyodor Yarochkin, Zhengyu Dong, Vladimir Kropotov, and Paul Pajares at the Black Hat Asia conference held in Singapore last week. Describing it as a  continuously evolving problem , the cybersecurity firm said...
