WhatsApp turns on End-to-End Encryption by default for its 1 Billion Users

WhatsApp turns on End-to-End Encryption by default for its 1 Billion Users

Apr 05, 2016
WhatsApp is updating its messaging app so that every text message and voice call will be encrypted for the company's one billion users. Yes, Whatsapp has finally implemented full end-to-end encryption , as promised a year ago. This means, from now every message, image or voice call you made will be secured by end-to-end encryption so that only you and the person you're communicating with can read the content of the message, and nobody in between, not even WhatsApp. In other words, this also means that WhatsApp would not be able to comply with any court order that demands access to the content of any conversation happens over its service. Starting today, you will see a notification on your WhatsApp conversation screen as your messenger becomes end-to-end encrypted, as shown in the screenshot. "Message you send to this chat and calls are now secured with end-to-end encryption. Tap for more info."  "This is because your messages are secured with a lock, ...

⚡ Weekly Recap: NFC Fraud, Curly COMrades, N-able Exploits, Docker Backdoors & More

Aug 18, 2025 Cybersecurity / Hacking News
Power doesn't just disappear in one big breach. It slips away in the small stuff—a patch that's missed, a setting that's wrong, a system no one is watching. Security usually doesn't fail all at once; it breaks slowly, then suddenly. Staying safe isn't about knowing everything—it's about acting fast and clear before problems pile up. Clarity keeps control. Hesitation creates risk. Here are this week's signals—each one pointing to where action matters most. ⚡ Threat of the Week Ghost Tap NFC-Based Mobile Fraud Takes Off — A new Android trojan called PhantomCard has become the latest malware to abuse near-field communication (NFC) to conduct relay attacks for facilitating fraudulent transactions in attacks targeting banking customers in Brazil. In these attacks, users who end up installing the malicious apps are instructed to place their credit/debit card on the back of the phone to begin the verification process, only for the card data to be sent to an attacker-controlled NFC relay...
Does WhatsApp Have A Privacy Bug That Could Expose Your Messages?

Does WhatsApp Have A Privacy Bug That Could Expose Your Messages?

Jan 11, 2019
In-short conclusion—Whatsapp service or its 45-days deletion policy doesn't seem to have a bug. For detailed logical explanation, please read below. An Amazon employee earlier today tweeted details about an incident that many suggest could be a sign of a huge privacy bug in the most popular end-to-end encrypted Whatsapp messaging app that could expose some of your secret messages under certain circumstances. According to Abby Fuller, she found some mysterious messages on WhatsApp, notably not associated with her contacts, immediately after she created a new account with the messaging app on her brand new phone using a new number for the very first time. Fuller believes that the mysteriously appeared content on her new account was the message history associated with the WhatsApp account of the previous owner of the same SIM/mobile number, which WhatsApp pushed to her phone. Since for WhatsApp, your phone number is your username and password is the OTP it sends to that n...

Explained — What's Up With the WhatsApp 'Backdoor' Story?

Explained — What's Up With the WhatsApp 'Backdoor' Story?

Jan 14, 2017
What is a backdoor? By definition: "Backdoor is a feature or defect of a computer system that allows surreptitious unauthorized access to data, " either the backdoor is in encryption algorithm, a server or in an implementation, and doesn't matter whether it has previously been used or not. Yesterday, we published a story based on findings reported by security researcher Tobias Boelter that suggests WhatsApp has a backdoor that "could allow" an attacker, and of course the company itself, to intercept your encrypted communication. The story involving the world's largest secure messaging platform that has over a billion users worldwide went viral in few hours, attracting reactions from security experts, WhatsApp team, and Open Whisper Systems, who partnered with Facebook to implement end-to-end encryption in WhatsApp. Note: I would request readers to read complete article before reaching out for a conclusion. And also, suggestions and opinions are ...
Researchers Warn of Self-Spreading WhatsApp Malware Named SORVEPOTEL

Researchers Warn of Self-Spreading WhatsApp Malware Named SORVEPOTEL

Oct 03, 2025 Malware / Online Security
Brazilian users have emerged as the target of a new self-propagating malware dubbed SORVEPOTEL that spreads via the popular messaging app WhatsApp. The campaign, codenamed Water Saci by Trend Micro, weaponizes the trust with the platform to extend its reach across Windows systems, adding the attack is "engineered for speed and propagation" rather than data theft or ransomware. "SORVEPOTEL has been observed to spread across Windows systems through convincing phishing messages with malicious ZIP file attachments," researchers Jeffrey Francis Bonaobra, Maristel Policarpio, Sophia Nilette Robles, Cj Arsley Mateo, Jacob Santos, and Paul John Bardon said . "Interestingly, the phishing message that contains the malicious file attachment requires users to open it on a desktop, suggesting that threat actors might be more interested in targeting enterprises rather than consumers." Once the attachment is opened, the malware automatically propagates via the deskt...

Beware — A New Wormable Android Malware Spreading Through WhatsApp

Beware — A New Wormable Android Malware Spreading Through WhatsApp

Jan 25, 2021
A newly discovered Android malware has been found to propagate itself through WhatsApp messages to other contacts in order to expand what appears to be an adware campaign. "This malware spreads via victim's WhatsApp by automatically replying to any received WhatsApp message notification with a link to [a] malicious Huawei Mobile app," ESET researcher Lukas Stefanko said. The link to the fake Huawei Mobile app, upon clicking, redirects users to a lookalike Google Play Store website. Once installed, the wormable app prompts victims to grant it notification access, which is then abused to carry out the wormable attack. Specifically, it leverages WhatApp's quick reply feature — which is used to respond to incoming messages directly from the notifications — to send out a reply to a received message automatically. Besides requesting permissions to read notifications, the app also requests intrusive access to run in the background as well as to draw over other apps, ...

200 Million WhatsApp Users Vulnerable to vCard Vulnerability

200 Million WhatsApp Users Vulnerable to vCard Vulnerability

Sep 09, 2015
WhatsApp recently claimed to have hit 900 Million monthly active users , but a dangerous security flaw in the web version of the popular instant messaging app puts up to 200 Million of its users at risk . Yes, the web-based extension of WhatsApp is vulnerable to an exploit that could allow hackers to trick users into downloading malware on their computers in a new and more sophisticated way. WhatsApp made its web client, WhatsApp Web , available to iPhone users just last month, after first rolling out its web-based instant messaging service for Android, Windows and BlackBerry Phone earlier in the year. Similar to Facebook Messenger, WhatsApp Web is an effective way to experience the mobile app in a web browser, allowing you to view all of the conversations you have made with your friends – including images, audio files, videos, GPS location and contact cards – straight on your PCs.

RatOn Android Malware Detected With NFC Relay and ATS Banking Fraud Capabilities

Sep 09, 2025 Mobile Security / Threat Intelligence
A new Android malware called RatOn  has evolved from a basic tool capable of conducting Near Field Communication ( NFC ) relay attacks to a sophisticated remote access trojan with Automated Transfer System ( ATS ) capabilities to conduct device fraud. "RatOn merges traditional overlay attacks with automatic money transfers and NFC relay functionality – making it a uniquely powerful threat," the Dutch mobile security company said in a report published today. The banking trojan comes fitted with account takeover functions targeting cryptocurrency wallet applications like MetaMask, Trust, Blockchain.com, and Phantom, while also capable of carrying out automated money transfers abusing George Česko, a bank application used in the Czech Republic.
