Popular instant messaging app WhatsApp on Thursday announced a new account verification feature that ensures that malware running on a user's mobile device doesn't impact their account. "Mobile device malware is one of the biggest threats to people's privacy and security today because it can take advantage of your phone without your permission and use your WhatsApp to send unwanted messages," the Meta-owned company said in an announcement. Called  Device Verification , the security measure is designed to help prevent account takeover (ATO) attacks by blocking the threat actor's connection and allowing targets of the malware infection to use the app without any interruption. In other words, the goal is to deter attackers' use of malware to steal WhatsApp authentication keys and hijack victim accounts, and subsequently impersonate them to distribute spam and phishing links to other contacts. This, in turn, is achieved by introducing a security-token th...

An unofficial version of the popular WhatsApp messaging app called YoWhatsApp has been observed deploying an Android trojan known as Triada. The goal of the malware is to steal the keys that "allow the use of a WhatsApp account  without the app ," Kaspersky  said  in a new report. "If the keys are stolen, a user of a malicious WhatsApp mod can lose control over their account." YoWhatsApp offers the ability for users to lock chats, send messages to unsaved numbers, and customize the app with a variety of theming options. It's also said to share overlaps with other modded WhatsApp clients such as FMWhatsApp and HeyMods. The Russian cybersecurity company said it found the malicious functionality in YoWhatsApp version 2.22.11.75. Typically spread through fraudulent ads on Snaptube and Vidmate, the app, upon installation, requests the victims to grant it permissions to access SMS messages, enabling the malware to enroll them to paid subscriptions without their...

WhatsApp, the world's most popular end-to-end encrypted messaging application, patched an incredibly frustrating software bug that could have allowed a malicious group member to crash the messaging app for all members of the same group, The Hacker News learned. Just by sending a maliciously crafted message to a targeted group, an attacker can trigger a fully-destructive WhatsApp crash-loop, forcing all group members to completely uninstall the app, reinstall it, and remove the group to regain normal function. Since the group members can't selectively delete the malicious message without opening the group window and re-triggering the crash-loop, they have to lose the entire group chat history, indefinitely, to get rid of it. Discovered by researchers at Israeli cybersecurity firm Check Point , the latest bug resided in the WhatsApp's implementation of XMPP communication protocol that crashes the app when a member with invalid phone number drops a message in the grou...

Finally, for the very first time, an encrypted messaging service provider is taking legal action against a private entity that has carried out malicious attacks against its users. Facebook filed a lawsuit against Israeli mobile surveillance firm NSO Group on Tuesday, alleging that the company was actively involved in hacking users of its end-to-end encrypted WhatsApp messaging service. Earlier this year, it was discovered that WhatsApp had a critical vulnerability that attackers were found exploiting in the wild to remotely install Pegasus spyware on targeted Android and iOS devices. The flaw (CVE-2019-3568) successfully allowed attackers to silently install the spyware app on targeted phones by merely placing a WhatsApp video call with specially crafted requests, even when the call was not answered. Developed by NSO Group, Pegasus allows access to an incredible amount of data from victims' smartphones remotely, including their text messages, emails, WhatsApp chats, ...

Cybercriminals are known to take advantage of everything that's popular among people in order to spread malware, and Google's official Play Store has always proved no less than an excellent place for hackers to get their job done. Yesterday some users spotted a fake version of the most popular WhatsApp messaging app for Android on the official Google Play Store that has already tricked more than one million users into downloading it. Dubbed Update WhatsApp Messenger , came from an app developer who pretended to be the actual WhatsApp service with the developer title "WhatsApp Inc."—the same title the actual WhatsApp messenger uses on Google Play. You might be wondering how the sneaky app developer was able to use the same title as the legitimate Facebook-owned maker of the messaging client—thanks to a Unicode character space. The app maker added a Unicode character space after the actual WhatsApp Inc. name, which in computer code reads WhatsApp+Inc%C2%A0 . ...

Are you sure the version of WhatsApp, or Skype, or VLC Player installed on your device is legitimate? Security researchers have discovered that legitimate downloads of several popular applications including WhatsApp, Skype, VLC Player and WinRAR have reportedly been compromised at the ISP level to distribute the infamous FinFisher spyware also known as FinSpy. FinSpy is a highly secret surveillance tool that has previously been associated with British company Gamma Group, a company that legally sells surveillance and espionage software to government agencies across the world. The spyware has extensive spying capabilities on an infected computer, including secretly conducting live surveillance by turning ON its webcams and microphones, recording everything the victim types with a keylogger, intercepting Skype calls, and exfiltration of files. In order to get into a target's machine, FinFisher usually uses various attack vectors, including spear phishing, manual installat...

Next time when someone sends you a photo of a cute cat or a hot chick on WhatsApp or Telegram then be careful before you click on the image to view — it might hack your account within seconds. A new security vulnerability has recently been patched by two popular end-to-end encrypted messaging services — WhatsApp and Telegram — that could have allowed hackers to completely take over user account just by having a user simply click on a picture. The hack only affected the browser-based versions of WhatsApp and Telegram, so users relying on the mobile apps are not vulnerable to the attack. According to Checkpoint security researchers, the vulnerability resided in the way both messaging services process images and multimedia files without verifying that they might have hidden malicious code inside. For exploiting the flaw, all an attacker needed to do was sending the malicious code hidden within an innocent-looking image. Once the victim clicked on the picture, the attacker coul...

WhatsApp has introduced a new security feature that fixes a loophole in the popular messaging platform, which if exploited, could allow an attacker to hijack victim's account with just knowing the victim's phone number and some hacking skills. The attack does not exploit any vulnerability in WhatsApp; instead, it relies on the way the account setup mechanism works. WhatsApp allows users to sign up to the app using their phone number, so if an attacker wants to hijack your WhatsApp account, they would require an OTP (One time password) send to your phone number. The attacker can grab this OTP by diverting the SMS containing the passcode to their own computer or phone, using either a malicious app or SS7 vulnerability , and then log into the victim's WhatsApp account. The attack even works in case the phone is locked. In August, Iranian state-sponsored hackers reportedly hijacked over dozens of Telegram accounts belonging to activists and journalists by exploiting a ...

However, a security flaw discovered by Check Point's security researcher Kasif...

If you rely on messaging apps to remain in contact with your family members and friends, then you may have to switch back to old-fashioned text messaging service in matter of weeks due to a new law currently going through Parliament. WhatsApp and Facebook Messenger to Ban in UK The popular messaging applications, including WhatsApp, Snapchat, iMessage and Facebook Messenger, could all potentially be banned in the UK under the controversial ' Snoopers Charter '. The Investigatory Powers Bill -- the so-called Snoopers Charter -- mentioned in the 2015 Queen's Speech , would allow UK government to eradicate instant messaging apps that refuse to switch off end-to-end encryption from their services. Earlier this year in light of the Charlie Hebdo shootings in Paris, Prime Minister David Cameron hinted at the crackdown when he claimed that he would ban encrypted messaging apps like Snapchat, WhatsApp and Messenger unless they didn't comply with new surve...

Pebble, a wristwatch that can connect to your phone - both iOS and Android - and interact with apps, has a hard-coded vulnerability that allows a remote attacker to destroy your Smartwatch completely. Pebble Smartwatch , developed and released by Pebble Technology Corporation in 2013, is considered as one of the most popular SmartWatches that had become the most funded project in the history of Kickstarter. Just two hours after its crowd-funding campaign launched, Pebble had already surpassed its $100,000 goal and at last had reached over $10.25 million pledged by nearly 70,000 Kickstarter backers.
