Popular instant messaging app WhatsApp has already been struggling for its existence in China ever since July when Chinese government blocked its users from sending photos and videos over the app. Now, it appears that China has largely blocked Facebook-owned WhatsApp in its latest step to tighten censorship as the country prepares for a major Communist Party gathering next month. Yes, WhatsApp no longer works in the country at all. China has a long history of blocking and limiting access to web services, especially social networks and Western-owned sites through its Great Firewall . The service currently blocks some 171 out of the world's leading websites, including Wikipedia, Twitter, Facebook, Instagram, and many Google services in mainland China. And now, it is WhatsApp. Although it's unclear how long the messaging app may remain inaccessible in the country, according to Symbolic Software, a Paris-based research firm that monitors WhatsApp's situation in Chi...

A seven-year-old cyber espionage campaign has targeted senior level executives from large global companies by using a specialized Advanced Persistent Threat (APT) , zero-day exploits, and well-developed keyloggers to extract information from them when they stay in luxury hotels during their business trips. The researchers at Moscow-based security firm Kaspersky Lab dubbed the threat as " DarkHotel APT ," appear to have the ability to know in advance when a targeted executive checks in and checks out of a hotel. The group has been operating in Asia since from 2009 but there have been infections recorded in the United States, South Korea, Singapore, Germany, Ireland and many others, as well. It uses hotel Wi-Fi networks to target elite executives at organisations in manufacturing, defense, investment capital, private equity, automotive and other industries. The group has access to zero day vulnerabilities and exploits, and it used them to infect victims. Threa...

Facebook announced a whole lot of new features at its 2018 Facebook F8 developers conference, including Dating on Facebook, letting users clear their web browsing history, real-time language translation within Messenger, and many more. Besides announcing exciting features for its social media platform, Facebook CEO Mark Zuckerberg also gave us a quick look at the features Facebook introduced for companies that it owns, like WhatsApp and Instagram. During Facebook's F8 conference on Tuesday, Zuckerberg announced a long-awaited feature for WhatsApp— Group Video Calling . Yes, you heard that right. WhatsApp would soon be adding a group video calling feature to the popular end-to-end messaging app, making it possible for its over billion users to have face-to-face conversations with multiple people at once. Although there are not many details about the WhatsApp group video calling feature at this moment, it is clear that WhatsApp will now allow four people to have one-on-one...

SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...

Joining the line with rival chat apps WhatsApp, Viber, Facebook Messenger, and Signal, the Telegram instant messaging service has finally rolled out a much-awaited feature for the new beta versions of its Android app: Voice Calling . And what's interesting? Your calls will be secured by Emojis, and quality will be better using Artificial Intelligence. No doubt the company brought the audio calling feature quite late, but it's likely because of its focus on security — the voice calls on Telegram are by default based on the same end-to-end encryption methods as its Secret Chat mode to help users make secure calls. Unlike Signal or WhatsApp, Telegram does not support end-to-end encryption by default; instead, it offers a 'Secret Chat' mode, which users have to enable manually, to completely secure their chats from prying eyes. However, the voice calling feature in Telegram supports end-to-end encryption by default, enabling users to secure their chats in a way ...

Popular end-to-end encrypted messaging service Signal on Monday disclosed the cyberattack aimed at Twilio earlier this month may have exposed the phone numbers of roughly 1,900 users. "For about 1,900 users, an attacker could have attempted to re-register their number to another device or learned that their number was registered to Signal," the company  said . "All users can rest assured that their message history, contact lists, profile information, whom they'd blocked, and other personal data remain private and secure and were not affected." Signal, which uses Twilio to send SMS verification codes to users registering with the app, said it's in the process of alerting the affected users directly and prompting them to re-register the service on their devices. The development comes less than a week after Twilio  revealed  that data associated with about 125 customer accounts were accessed by malicious actors through a phishing attack that duped the comp...

Russia's communications regulator Roskomnadzor has threatened Apple to face the consequences if the company does not remove secure messaging app Telegram from its App Store. Back in April, the Russian government banned Telegram in the country for the company's refusal to hand over private encryption keys to Russian state security services to access messages sent using the secure service. However, so far, the Telegram app is still available in the Russian version of Apple's App Store. So in an effort to entirely ban Telegram, state watchdog Roskomnadzor reportedly sent a legally binding letter to Apple asking it to remove the app from its Russian App Store and block it from sending push notifications to local users who have already downloaded the app. Roskomnadzor's director Alexander Zharov said he is giving the company one month to remove the Telegram app from its App Store before the regulator enforces punishment for violations. For those unfamiliar with...

GO SMS Pro, a popular messaging app for Android with over 100 million installs, has been found to have an unpatched security flaw that publicly exposes media transferred between users, including private voice messages, photos, and videos. "This means any sensitive media shared between users of this messenger app is at risk of being compromised by an unauthenticated attacker or curious user," Trustwave Senior Security Consultant Richard Tan said in a report shared with The Hacker News. According to Trustwave SpiderLabs, the shortcoming was spotted in version 7.91 of the app, which was released on the Google Play Store on February 18, 2020. The cybersecurity firm said it attempted to contact the app makers multiple times since August 18, 2020, without receiving a response. But checking the app's changelog, GO SMS Pro received an update (v7.92) on September 29, followed by another subsequent update, which was published yesterday. The latest updates to the app, however...

Good News for WhatsApp users! The widely popular messaging service is going completely free. And you'll be able to use WhatsApp without paying a penny. Old WhatsApp users might not be aware of this, but WhatsApp introduced the subscription fees for its service a few years ago, forcing new users to pay an annual 99 cents (~$1) subscription fee after the first year. However, WhatsApp announced Monday that the Facebook-owned company is dropping its annual subscription fee to make its service free to all users. While announcing the plan today, WhatsApp's founder Jan Koum stated that the annual subscription fee was still a barrier to some users. "As we have grown, we have found that this approach has not worked well," WhatsApp admitted in a company blog post today. "Many WhatsApp users do not have a debit or credit card number, and they worried they'd lose access to their friends and family after their first year." What will be What...

Cybersecurity leaders aren't just dealing with attacks—they're also protecting trust, keeping systems running, and maintaining their organization's reputation. This week's developments highlight a bigger issue: as we rely more on digital tools, hidden weaknesses can quietly grow.  Just fixing problems isn't enough anymore—resilience needs to be built into everything from the ground up. That means better systems, stronger teams, and clearer visibility across the entire organization. What's showing up now isn't just risk—it's a clear signal that acting fast and making smart decisions matters more than being perfect. Here's what surfaced—and what security teams can't afford to overlook. ⚡ Threat of the Week Microsoft Fixes 5 Actively Exploited 0-Days — Microsoft addressed a total of 78 security flaws in its Patch Tuesday update for May 2025 last week, out of which five of them have come under active exploitation in the wild.

A zero-day vulnerability has been discovered in the desktop version for end-to-end encrypted Telegram messaging app that was being exploited in the wild in order to spread malware that mines cryptocurrencies such as Monero and ZCash. The Telegram vulnerability was uncovered by security researcher Alexey Firsh from Kaspersky Lab last October and affects only the Windows client of Telegram messaging software. The flaw has actively been exploited in the wild since at least March 2017 by attackers who tricked victims into downloading malicious software onto their PCs that used their CPU power to mine cryptocurrencies or serve as a backdoor for attackers to remotely control the affected machine, according to a blogpost on Securelist. Here's How Telegram Vulnerability Works The vulnerability resides in the way Telegram Windows client handles the RLO (right-to-left override) Unicode character (U+202E), which is used for coding languages that are written from right to left, li...

On one end, where governments of countries like U.K is criticizing end-to-end encryption and considering to ban the encrypted communication apps like Snapchat, CryptoCat, WhatsApp and Apple's iMessage. On the other hand, the Internet community has come up with a new and rather more secure encrypted communication app. Dubbed Peerio , an " encrypted productivity suite " designed to offer much more usable alternative to PGP email and file encryption, so that every individual user and business can encrypt everything from Instant Messages to online file storage. Peerio, released on Wednesday, is designed by 24-year-old Nadim Kobeissi – the creator of the end-to-end encrypted group messaging app Cryptocat and the encrypted file-sharing app MiniLock . " With Peerio everything you share or communicate with your team is secured with state-of-the-art encryption , and it's as easy as using Gmail. You don't need to learn to use it, " Kobeissi told Wired. ...

Security researchers have illustrated a new app-in-the-middle attack that could allow a malicious app installed on your iOS device to steal sensitive information from other apps by exploiting certain implementations of Custom URL Scheme . By default on Apple's iOS operating system, every app runs inside a sandbox of its own, which prevent all apps installed on the same device from accessing each other's data. However, Apple offers some methods that facilitate sending and receiving very limited data between applications. One such mechanism is called URL Scheme, also known as Deep Linking, that allows developers to let users launch their apps through URLs, like facetime:// , whatsapp:// , fb-messenger:// . For example, when you click "Sign in with Facebook" within an e-commerce app, it directly launches the Facebook app installed on your device and automatically process the authentication. In the background, that e-commerce app actually triggers the URL Sch...

The identity of the second threat actor behind the Golden Chickens malware has been uncovered courtesy of a "fatal" operational security blunder, cybersecurity firm eSentire said. The individual in question, who lives in Bucharest, Romania, has been given the codename Jack. He is one of the two criminals operating an account on the Russian-language Exploit.in forum under the name "badbullzvenom," the other being " Chuck from Montreal ." eSentire characterized Jack as the true mastermind behind Golden Chickens. Evidence unearthed by the Canadian company shows that he is also listed as the owner of a vegetable and fruit import and export business. "Like 'Chuck from Montreal,' 'Jack' uses multiple aliases for the underground forums, social media, and Jabber accounts, and he too has gone to great lengths to disguise himself," eSentire researchers Joe Stewart and Keegan Keplinger said . "'Jack' has taken great pa...

Privacy conscious phone users are being offered a new app that claims to be the world's first totally secure messaging service. A London-based iPhone messaging app claims to be unhackable and is offering reward to anyone who can intercept a message sent by it.  Redact believes that messages sent via the app are completely secure, and to prove it a reward of £10,000 has been offered. The application creates a secure and encrypted peer-to-peer network between two iPhones, with messages sent directly from one phone to another and not through the company's servers.  The company has already offered its Secure Messenger service for free to MPs and submitted the technology to CESG, the Government's National Technical Authority for Information Assurance, which provides advice on the security of communications and electronic data. With Redact there are no user names, phone numbers or email addresses. Instead, new users are automatically assigned a unique PIN, simi...

Twitter has been adopting new trends at a snail's pace. But it's better to be late than never. Since 2013 people were speculating that Twitter will bring end-to-end encryption to its direct messages, and finally almost 5 years after the encryption era began, the company is now testing an end-to-end encrypted messaging on Twitter. Dubbed " Secret Conversation ," the feature has been spotted in the latest version of Android application package (APK) for Twitter by Jane Manchun Wong, a computer science student at the University of Massachusetts Dartmouth. End-to-end encryption allows users to send and receive messages in a way that no one, be it an FBI agent with a warrant, hacker or even the service itself, can intercept them. However, it seems like the Secret Conversation feature has currently been available only to a small number of users for testing. So, if you are one of those lucky ones, you will be able to send end-to-end encrypted Secret Conversation thro...

Facebook's Free Basics Internet service has been Blocked in India. The Telecom Regulatory Authority of India (TRAI) has banned mobile carriers and broadband providers to charge customers based on what services or content they access over the Internet. Under Prohibition of Discriminatory Tariffs for Data Services Regulations, 2016, "no service provider shall offer or charge discriminatory tariffs for data services on the basis of content." With this, Facebook's Free Basics is dead in India. All Zero-Rated Internet Services are BLOCKED!  It is not just Facebook's Free Basics Internet program that has been blocked inside the country, but also the zero-rated internet services altogether. Zero-rated internet services means those services that allow people access to some websites and web services without utilizing any of their mobile data allowance. Under the new regulation, no such services are now allowed. Free Basics (previously known by Int...

Facebook has introduced a new feature in its platform that has been designed to make it easier for bug bounty hunters to find security flaws in Facebook, Messenger, and Instagram Android applications. Since almost all Facebook-owned apps by default use security mechanisms such as Certificate Pinning to ensure integrity and confidentiality of the traffic, it makes it harder for white hat hackers and security researchers to intercept and analyze network traffic to find server-side security vulnerabilities. For those unaware, Certificate Pinning is a security mechanism designed to prevent users of an application from being a victim of network-based attacks by automatically rejecting the whole connection from sites that offer bogus SSL certificates. Dubbed " Whitehat Settings ," the new option now lets researchers easily bypass Certificate Pinning on the Facebook-owned mobile apps by: Disabling Facebook's TLS 1.3 support Enabling proxy for Platform API requests ...

A new computer worm is denying Facebook users access to their accounts. The worm, named "W32.Yimfoca" by the security company Symantec, spreads through Yahoo! Messenger and specifically targets Facebook users. It forces them to complete surveys before they can log into their profiles. The worm begins by sending an instant message containing a corrupted link. When a user clicks the link, the worm installs malware on their system. Later, when users visit Facebook, they see a message stating, "Your account is suspended. To make your account active, you need to complete one of these surveys," followed by a list of options like "Test Your Celebrity IQ here" and "Win a FREE iPhone 4." If users choose to fill out a survey, another message appears: "You have only 3 minutes to fill out the selected survey or you will not have access to your account." Each time a survey is completed, the creators of the worm earn $1, according to Symantec. The ...
