Is WhatsApp Really Safe in 2025?
In 2025, the question "is WhatsApp safe?" isn't just being asked by cybersecurity professionals – it's on the minds of parents, students, entrepreneurs, activists, and even celebrities.
Scandals involving Facebook (now Meta), rising government surveillance, and increasingly sophisticated cybercrime have left many wondering: is WhatsApp safe to use when your privacy matters most? With over 2 billion users, WhatsApp is a global communications giant – and also a prime target. The stakes are high. One wrong tap, and a private photo, a confidential contract, or a medical diagnosis could end up in the wrong hands.
The truth is, many users assume their chats are protected simply because they see a padlock icon and read the words "end-to-end encryption." But what does that really mean? Is WhatsApp safe, or are we just being lulled into a false sense of security?
WhatsApp's Security Architecture: The Promise of End-to-End Encryption
Explanation of WhatsApp's End-to-End Encryption
Yes, WhatsApp uses end-to-end encryption (E2EE) – a term that sounds incredibly secure. And technically, it is. Developed in collaboration with Open Whisper Systems (creators of the Signal protocol), WhatsApp’s E2EE means that your messages are scrambled into unreadable gibberish from the moment they leave your phone until they reach the recipient. This architecture is designed to prevent WhatsApp, its parent company Meta, or any third party that might intercept the data during transmission from reading the message content or listening to calls.
So, is WhatsApp safe to use? In theory – yes. In practice – it’s complicated.
What E2EE Secures: Messages, Media, Calls, Status Updates
WhatsApp’s E2EE covers:
- Text messages (both individual and group chats)
- Shared media files (such as photos, videos, and documents)
- Voice messages
- Voice and video calls
- Status updates
Each communication is encrypted with a unique lock and key system that regenerates frequently. It’s like sending a letter that can only be opened by one specific fingerprint. But while this sounds rock-solid, users often overlook what E2EE doesn’t protect.
Understanding the Limits of WhatsApp’s Famous Encryption Promise
Ask yourself again: is WhatsApp safe? If your messages are encrypted, then what’s the problem?
Here’s where it gets tricky. WhatsApp encrypts messages in transit – but:
- Metadata isn’t encrypted. This includes who you talk to, when, and for how long. Imagine someone not seeing the content of your letter, but knowing exactly whom you sent it to, how often, and at what time.
- Cloud backups are vulnerable. If your chats are backed up to Google Drive or iCloud, they may no longer be protected by E2EE – unless you explicitly enable encrypted backups (more about this in the section below).
- Device compromise. If malware infects your phone, even the strongest encryption won’t protect you. Hackers can capture screenshots, log keystrokes, or intercept messages before they’re encrypted.
So, while WhatsApp has strong encryption in theory, real-world usage often leaves some holes big enough for privacy nightmares to slip through.
Additional WhatsApp Security Features
WhatsApp also offers:
- Two-step verification: This adds a six-digit PIN to your account, which is required when registering your phone number with WhatsApp again (e.g., if your SIM card is stolen or your account is being ported). This helps protect against SIM swap attacks. It's a valuable feature, and we at Atomic Mail always recommend enabling 2FA/MFA wherever possible.
- Security code change notifications: You can be notified when a contact's security code changes. This usually happens when they reinstall WhatsApp or change phones. While most often benign, it could, in rare cases, indicate a man-in-the-middle attack or that someone else has registered your contact's account.
- Biometric authentication: On supported devices, you can require fingerprint or face authentication to open WhatsApp, even if your phone is already unlocked. This adds a layer of protection against someone who might gain temporary physical access to your phone.
- Encrypted cloud backups: WhatsApp now allows optional E2EE for cloud backups (on Google Drive or iCloud). However, it's not enabled by default, so many users may leave their cloud backups vulnerable.
- Disappearing messages: This feature allows users to set messages in a chat to automatically delete after a predefined period – 24 hours, 7 days, or 90 days. This applies only to new messages sent after the feature is enabled and is intended to enhance privacy by reducing the long-term retention of conversational data.
- View once: Designed for sharing photos and videos, this feature makes media disappear after the recipient opens it once, intending to prevent casual saving or forwarding. However, its effectiveness is limited as recipients can often still capture content using screenshots or other devices, questioning how truly is WhatsApp safe for ephemeral media.
These features offer users more granular control over their data and app access. However, it's important to recognize their limitations; for instance, disappearing messages do not prevent recipients from copying or screenshotting content before it auto-deletes.
Advanced Chat Privacy Features
In April 2025, WhatsApp introduced a new set of "Advanced Chat Privacy" settings applicable to both individual chats and groups. These settings aim to provide users with greater control over how their chat content is handled by others, allowing them to:
- Block recipients from exporting chats
- Prevent the auto-downloading of media to their phones
- Restrict the use of messages for AI features
The idea is to make it harder for chat content to be moved or used outside of WhatsApp. We'll need to keep an eye on how well this feature works and how it changes, particularly the mention of "AI features," which may hint at Meta's plans for integrating AI capabilities within its messaging services.

While these additions can offer tangible benefits, they also introduce complexity and may not always address more fundamental concerns, such as the extensive collection of metadata.
Vulnerabilities, Breaches, and Real-World Incidents
Even though WhatsApp's end-to-end encryption for message contents, the platform is still vulnerable to security issues, just like any other complex software. There have been a few real-world security incidents linked to WhatsApp in the past. These incidents show that the problem goes beyond just encrypting messages in transit, and includes client applications, endpoint devices, and the human element.
WhatsApp Vulnerability Overview (Recent & Significant CVEs)
Known Vulnerabilities and Exploits
- The March 2025 Windows Desktop Vulnerability (CVE-2025-30401)
In early 2025, a high-severity vulnerability was disclosed in WhatsApp for Windows (versions prior to 2.2450.6). This flaw allowed attackers to disguise malicious executables as harmless files like images. If a user opened such a file within WhatsApp, it could lead to arbitrary code execution on their system. This kind of vulnerability is particularly dangerous as it leverages user trust in shared media.
- The March 2025 Check Point Zero-Day Video File Vulnerability
Also in March 2025, cybersecurity firm Check Point reportedly uncovered a critical zero-day vulnerability in WhatsApp that allowed attackers to execute malicious code by sending specially crafted video files. According to reports, merely viewing the malicious video could silently deploy scripts on the target's device, granting attackers access to sensitive information such as local storage, camera, microphone, and even WhatsApp chat logs.
High-Profile Spyware Attacks
In 2019, WhatsApp confirmed that over 1,400 users, including journalists, diplomats, and human rights activists, were targeted using a vulnerability in WhatsApp’s voice call feature. Victims didn’t even need to answer the call – just receiving it was enough for Pegasus to infiltrate their phone.
Legal battles and investigations continuing into late 2024 and early 2025 revealed the persistent nature of these attacks. For instance, court documents in May 2025 confirmed NSO Group continued targeting WhatsApp users even after Meta filed its initial lawsuit in 2019. And Meta only announced on 6 May 2025 that they had finally won the NSO.
- Paragon's Graphite Spyware
In a similar vein, late 2024 saw WhatsApp addressing a zero-click exploit used to deploy "Graphite" spyware by another commercial surveillance vendor, Paragon. Security researchers at Citizen Lab played a key role in investigating these attacks, which reportedly involved sending malicious PDF files through WhatsApp groups to deploy the spyware.
Reports in early 2025 confirmed that around 90 individuals, including journalists and civil society members across multiple countries, were targeted.
The Scale of Impact: Growing Trends & Statistics
- India's Ministry of Home Affairs (MHA) reported that in the first three months of 2024 alone, a staggering 43,797 complaints of cyber fraud were directly related to WhatsApp.
- In Singapore, the police force reported in early 2025 that WhatsApp remained a primary channel for scammers.
- Action Fraud UK data released in late 2024 showed a 230% increase in "Friend-in-Need" scams targeting WhatsApp users over the previous year, with reported losses averaging £1,500 per victim.
Why WhatsApp is a Target for Scammers
Scammers flock to WhatsApp not just by chance, but because specific characteristics of the platform, coupled with user psychology, create a fertile ground for their illicit activities. Understanding these factors is key for anyone trying to determine is WhatsApp safe to use.
Several factors contribute to WhatsApp's attractiveness for scammers:
- Massive User Base: With billions of users globally, WhatsApp offers scammers an unparalleled ocean of potential victims for minimal effort.
- Exploited Perception of Security: Ironically, the platform's emphasis on security like E2EE can be twisted, as criminals leverage the perception that encrypted apps are inherently "safe," causing users to lower their guard.
- Ease of Account Creation: Scammers can quickly set up accounts, often only needing a disposable phone number, making them difficult to pin down.
- Rapid, Wide Reach: The platform allows instant dissemination of messages to large audiences, especially through group chats which can be infiltrated.
- Anonymity and Evasion: The inherent difficulties in tracing perpetrators across international borders, combined with E2EE, can inadvertently shield scammers if the platform's detection mechanisms aren't robust enough at scale.
While WhatsApp implements spam detection and user reporting tools, the decentralized nature of messaging makes it hard to catch every threat. The very features that make WhatsApp convenient for users also make it convenient for scammers.
WhatsApp's Data Practices and Privacy Implications
End-to-end encryption ensures that the actual content of messages, photos, videos, and calls remains private from WhatsApp and Meta. However, WhatsApp collects a substantial amount of metadata – data about the communications and the users. This metadata can include :
- Account Information: Phone number, profile name, profile picture, "about" information (status message).
- Usage Information: How and when users interact with the service, including features used, settings, frequency and duration of activities, interaction with businesses, and the time, frequency, and duration of calls.
- Device and Connection Information: Hardware model, operating system information, app version, browser information, IP address, mobile network information (including phone number and mobile country/network codes), signal strength.
- General Location Information: While precise location shared within E2EE chats is not visible to WhatsApp, the platform may collect general location information derived from IP addresses or phone number country codes for service provision and diagnostics.
- Contacts: WhatsApp requires access to users' phone contacts to provide its service, but states it does not share contact lists with other Meta Companies for their own use.
- Status Updates: While the content of status updates is E2EE, metadata about them may be collected.
WhatsApp explicitly states that it does not keep logs of who everyone is messaging or calling on a routine basis for surveillance purposes, nor can it see precise locations shared within E2EE chats. Nevertheless, the metadata that is collected can be highly revealing.
So, is WhatsApp safe to use when its parent company, Meta (formerly Facebook), is known for aggressive data monetization? That’s where things get murky.
WhatsApp’s infamous 2021 privacy policy update attempted to force users to share more data with Meta’s broader ecosystem – for advertising, business messaging, and more. The backlash was immediate. Millions of users fled to privacy-first platforms like Signal and Telegram. And for good reason.
Even today, WhatsApp shares data with Meta for “operational purposes,” which includes syncing with Facebook services. This isn’t about your message content » it’s about the context of your conversations. And in the data economy, context is gold.
The line between security and privacy is thin – and WhatsApp often blurs it.
Is WhatsApp Safe from Government Surveillance?
Another major concern is government surveillance. And rightly so. The question is WhatsApp safe from the prying eyes of state agencies isn’t theoretical. It’s real, urgent, and complex.
WhatsApp has proudly refused to build backdoors for governments. In fact, in some cases, it has even pushed back against legal demands. But there's a catch.
WhatsApp can’t read your encrypted messages – but it can and does share metadata (discussed earlier) with authorities.
In 2024 alone, Meta disclosed data in response to over 78% of law enforcement requests involving WhatsApp.
Moreover, once data is backed up in the cloud (Google Drive or iCloud), it’s potentially accessible via subpoenas or direct access. Unless users specifically enable encrypted backups, that data is fair game.
And let’s not forget the international alliances like Five Eyes, where countries share intelligence – including metadata – across borders. If one country can’t request it directly, another might.
So, is WhatsApp safe to use in environments where political sensitivity or regulatory overreach is a factor? The answer depends on your threat model – but for many, the risks are far too high. While E2EE offers some protection, government access to metadata, legal pressures against encryption, and potent spyware mean WhatsApp provides limited safety from determined state surveillance.
Is WhatsApp Safe for Sending Private Photos and Sensitive Files?
Let’s cut to the chase: is WhatsApp safe when it comes to sending private photos, IDs, financial documents, or anything you wouldn’t want leaked? It depends – on more than just encryption.
Yes, messages and media are end-to-end encrypted in transit. That means only you and the recipient should be able to view them. But here’s the catch: once that file reaches a phone, encryption ends. The photo is stored in the device gallery, often automatically. From that moment, it’s vulnerable to:
- Malware or spyware on the recipient’s device
- Cloud backups if the gallery syncs with iCloud or Google Photos
- Accidental sharing (or worse, intentional misuse)
- Screenshots or screen recordings
WhatsApp also compresses media files, sometimes degrading quality. More importantly, this process opens up opportunities for metadata leaks – when the file was taken, geolocation tags, device info.
The platform does offer an optional "View Once" mode, which deletes photos or videos after being viewed. But even that isn’t foolproof. Screenshots or pictures from other devices can still be taken.
The takeaway: is WhatsApp safe for sending sensitive media? While it's safer than sending them via unencrypted email or SMS due to E2EE in transit, the numerous risks at the endpoints, through backups, and via recipient actions mean it's far from a secure vault. For truly confidential media, especially business-sensitive documents or intimate photos, relying solely on WhatsApp is a significant risk.
Safer Alternatives to WhatsApp: What Privacy Experts Use Instead
So, if you’ve been wondering, is WhatsApp safe, and feel uneasy about the answer – what are your options?
Privacy experts, security researchers, and journalists around the world are moving away from mainstream platforms like WhatsApp for very good reasons. Here are the alternatives they rely on:
1. Signal: Built with privacy at its core, Signal offers end-to-end encryption powered by the same Signal Protocol that WhatsApp uses – but with none of the corporate baggage. It doesn’t store metadata, doesn’t serve ads, and doesn’t log who you're talking to. This is often the go-to for whistleblowers, activists, and even governments.
2. Threema: Based in Switzerland, Threema is one of the few messaging apps that requires no phone number, ensuring anonymity. It encrypts everything – messages, files, even status messages – and stores data only on your device.
3. Atomic Mail: For professionals and privacy-conscious individuals, email remains essential. But not just any email. If you're asking, is WhatsApp safe to use, consider whether you’re also relying on Gmail, Outlook, or other data-mining services for your sensitive communication.

Conclusion and Recommendations for Users
WhatsApp's safety is a complex issue that requires an understanding of its strengths and weaknesses within the broader context of its operation. Although WhatsApp provides a substantial level of protection for communication content through its default end-to-end encryption, this feature alone does not make the platform completely "safe" from all threats or privacy violations.
If you're a casual user who values convenience and isn't exchanging anything sensitive, WhatsApp may feel “safe enough.” But if you’re a freelancer, founder, journalist, lawyer, or just someone who values true digital privacy, you deserve more.
You deserve Atomic Mail – the encrypted email built for people who don’t want to be watched.
Your data, your rules. No trackers. No surveillance. No third-party snooping.
