Everything you need to know about Whatsapp Security
is whatsapp secure ? Lately, whenever we wanted to maintain constant communication with others, we moved to share our WhatsApp accounts. We chitchat, share, receive and reconnect with others from around the world. It doesn’t happen in a vacuum that 1 million people do register on WhatsApp daily. Indeed, the app has managed to remain at the top of the list of the most popular messaging apps for nearly 10 years now. Despite the increasing number of daily active users in WhatsApp, up to 300 million users, many still question the privacy and security of the files and pictures sent via WhatsApp.
Therefore, is the safety of your data emphasized as a big deal in WhatsApp? This question is a highlight when it comes to the projected trends in the number of WhatsApp users’ satisfaction after being owned by Facebook.
“Privacy and Security is in our DNA,” WhatsApp Declared
According to WhatsApp, a giant control over any kind of information sent via WhatsApp platform is secured; let it be a photo, video, voice message, document or call. WhatsApp has assured to intensify more efforts to keep any third party out of interference. To this end, WhatsApp adds more layers of protection in the form of end-to-end encryption and backup to cloud methods.
As a definitive security mechanism, end-to-end encryption means that a message is coded on the sender’s device and decoded on the recipient’s device. As WhatsApp has made clear, it transforms every data sent into encrypted codes that no one but the sender and receiver can read its content. Also, for more security purposes WhatsApp has excluded itself from the picture in order not to give any chance of interference between the two users. This process is automatically undertaken by WhatsApp.
- Two different keys are created (public & private) when the user first opens WhatsApp. The mechanism of encryption is set on the phone itself.
- The private key will stay with the recipient, whereas the central WhatsApp server passes the public key to the receiver.
- Even before it hits the centralized server, the public key encrypts the sender’s message on the phone.
- The encrypted message is transmitted via the server.
- The message can only be opened using the receiver’s private key.
How Do You Verify that WhatsApp is Using End-to-End Encryption?
You can assure the mechanism of encryption that WhatsApp has brought into practice through simple taps you perform manually:
- Click in the contacts name on WhatsApp to open the info screen.
- Tap on “Encryption”.
- Scan your contacts’ QR code or visually compare the 60-digit number.
- In case they match, your chats are encrypted.
Is the Government Proposal to Have a Backdoor Through the Users Data Compatible with End-to-End Encryption?
WhatsApp has always considered this proposal as troublesome. It clarifies that this won’t just open the data to government agencies but to cyber criminals too. It is a risky step to give some official agencies access to the data of its users in order to help reveal the identity of some terrorists and invaders. Furthermore, at the same time, this backdoor will expose millions more innocent people to danger. WhatsApp has made it clear when it can collaborate with law enforcement officials who ask for user information regarding serious issues of imminent harm or risk of death or physical injury. That is to say, WhatsApp will “search for and disclose information that is specified with particularity in an appropriate form of the legal process and which [WhatsApp is] reasonably able to locate and retrieve.”
What Other Apps that Have End-to-End Encryption?
WhatsApp isn’t the only app in the market with this master feature. There are some other encrypted messaging apps helping you to stop people from snooping on your conversations. For example, Signal, Telegram, Wickr Me and Line. However, the encryption in these apps is not enabled by default, while end-to-end encryption is always activated in WhatsApp, and there’s no way to turn it off.
WhatsApp displays an option for you to backup all messages by uploading a copy of your data on Google Drive (Android) or iCloud (iPhone). This makes an advantage when you are changing phones and need to restore your WhatsApp account. It is important to understand that backing up your account within WhatsApp isn’t equivalent to exporting WhatsApp content beyond WhatsApp. To put it simply:
- Backups are stored in an encrypted WhatsApp database format. This method can’t be accessed outside WhatsApp. To back up chats: Go to WhatsApp > tap More options > Settings > Chats > Chat backup > BACK UP.
- Exporting content to your Google Drive isn’t encrypted and can be opened and read outside WhatsApp. You can use the export chat feature to export a copy of your chat history from an individual or group chat. Open the individual or group chat and tap More options > More > Export chat > Choose whether to export with media or without media.
You may be feeling more secure and in safe hands after reading all that WhatsApp has to offer in terms of privacy and security. Yet, let’s dive deeper.
To Shed Light on Some of WhatsApp Drawbacks
Nothing in this world is perfect, and it is known that human is to err, even for an app that is used worldwide with more than 65 billion messages sent per day.
No way but a third party involved
It is great to have an option when you are in a pressing need to change your phone while keeping your data saved. However, you still lose control over what is hit via WhatsApp. That is to say, security isn’t 100% guaranteed as all that you share can be screenshotted, forwarded or stored on other devices. It is not calming to get to see your words are shattered around with more than a third party! But that doesn’t necessarily mean to have it only from individuals you are talking to, but, indeed, it may involve another reason where WhatsApp choose to invest your data for promotional purposes. Proceed reading to understand how.
Secondly, you must have already received some infected links or files via WhatsApp enticing you to take action, and then, boom! You fall a victim to a malware threat. You have no idea how vulnerable your data becomes when exposed to such malware threats due to some bugs allowing hackers to use malicious ways to attack your device. For example, WhatsApp sues Israel’s NSO firm for illegally helping spies hack phones of roughly 1,400 users across four continents. It was of a serious matter, for their targets included diplomats, political dissidents, journalists and senior government officials.
It can be simpler since a malicious GIF inserted in your device through any channel can essentially put all the content of your device at risk.
Have you come across the nickname “Agent Smith”?
It is another threat announced to have attacked Android devices without having their users alerted. According to Forbs, “Agent Smith” is considered as, ” the worst attacks on Android operating system in the recent memory.” They declared that it only intends to pop up some advertisements when the user opens WhatsApp, but who knows whether such malware will go beyond the ad. It goes into far more burdensome and dangerous purposes, such as banking credential theft and eavesdropping.
How Safe Are Your Photos on WhatsApp?
As we aforementioned, you should always keep in mind that hacks do occur. When hackers mean to pry on your information and pictures, they will work day and night to drag them out. Also, this process gets easier when you connect to insecure Wi-Fi networks, like that at the airport or crowded coffee places on the street. Well, the data plans, in this case, represent a more secure option for you. Visit here to know more about how Numero eSIM Data Plans will save your back.
Although you can block your WhatsApp from storing sent and received photos on your phone’s photo albums, you still should make sure your private photos stay private. The good news after the end-to-end encryption has enabled, WhatsApp stores all communications including audios, videos and images on its servers upon sending until all recipients have received them. Once all recipients have received the photo, it’s deleted from WhatsApp’s servers. This is why it tells you when you click on an old photo sent via WhatsApp ” can’t view this photo because it’s no longer on your phone.” And they remain blurred in your chats! It is still concerning because your media can be stick in there for not less than 30 days.
After all, you should always act like they are stored forever. Also, just be smart about who you are sending pictures to and smarter about what kinds of pictures you send.
Change your WhatsApp Number/Phone Without Losing your Data
First: Changing your WhatsApp Phone Number
WhatsApp has covered all that you need when you change your WhatsApp number. That is, you have the “Change Number” feature allowing you to change your number in WhatsApp on your same phone:

After using this feature, the account associated with your old phone number will be deleted, and your profile information, groups and setting will be migrated to your new phone number. WhatsApp enables you to notify your contacts of your new phone number without going through the hassle of informing them all individually.
Second: Changing Your Phone into a Different Type
It is worth mentioning that all your information is tied to the phone number. For example, if you want to change your phone from an iPhone to an Android without changing your number, you can simply download WhatsApp on the new phone and verify your same number. Yet, you have to note that changing the type of phone doesn’t allow you to migrate messages.
Third: Changing Your Phone into a Same Type
Changing your phone from, for example, Android to Android gives an option to migrate your messages. That is, you can transfer your WhatsApp data to a new phone by restoring from Google Drive or a local backup. Check how from right here.
Is your old account subject to hacking if you forget to delete it? In case the new owner of your old number activates WhatsApp on his new phone after 45 days, all of your account information linked to that phone number will be removed entirely. However, in all cases, stay safer by wiping all your data and SD card before giving away your old phone. This is for further insurance that no one will reach your data.
Cases That Cause Temporarily Banned Accounts
You may receive a notification informing that your account is “Temporarily Banned” due to some violation you have broken related to WhatsApp terms and conditions. Misuse of WhatsApp my drive your number to be on the ban list when:
- Sending illegal, offensive, defamatory or dangerous messages.
- Sending rumors, links with malware or ethically harassing materials.
- Impersonating someone.
- Sending too many messages, automated and bulk messages to those users not on your contact list, for this is considered ad spamming messages.

In case you haven’t done serious damage, your account may be banned for a minimum of 48-72 hours. If it takes a longer time for WhatsApp to remove the ban, you need to send an email to firstname.lastname@example.org and politely inquire for reactivation. On the contrary, it may be suspended for life if the act you have pursued has dangerously occurred. Then all that you have in hand is creating a new account with a new phone number.
WhatsApp Privacy Tips
Gain the Permission of Others

However, you still have to log out from WhatsApp Web every time you finish using it on the PC, for this will protect your messages from being read by anyone who uses the PC. If you’d like to learn a bit more about the WhatsApp Web, we’ve broken it down further for you here.
WhatsApp Is Encrypted, the Cloud Is Not
In case you decide to back up your WhatsApp data and restore them via the cloud or any other external server, no encryption is anymore ensured. The hacking of your data will be easier because hackers won’t need to hack your WhatsApp account. Instead, they can access your data by directly hitting your drive. You can explore ways to make sure the cloud you are using to back up your data is clear and safe, for example, here Google has explained a few steps to make your account more secure.
Steps You Should Take for Your Stolen Account/Phone
It is uncommon to have your account stolen without sharing the SMS verification code with others or losing your phone.
- The first thing to do when you suspect that your account is stolen is notifying your contacts of friends and family about the issue so that no impersonate acts occur.
- You need to delete the WhatsApp app you have and reinstall another one.
- Sign into the new WhatsApp app with your phone number being used by someone currently and verify your phone number by entering the 6-digit code you receive via SMS.
- Only after you enter the 6-digit SMS code will the other party automatically log out from your account. WhatsApp indicates, “you might also be asked to provide a two-step verification code. If you don’t know this code, the individual using your account might have enabled two-step verification. You must wait 7 days before you can sign in without the two-step verification code.”
Sometimes you, unfortunately, can’t help the loss of your phone and need a way to assure that no one is seeing your personal WhatsApp. Therefore, you have to run and lock your SIM card so that whoever is using your lost phone won’t be able to verify the account. After that, you buy a new SIM card with the same phone number to reuse your WhatsApp account again and have it deactivated on the stolen phone. This is because “WhatsApp can only be activated with one phone number on one device at a time.” You also can email the WhatsApp team with the phrase “Lost/Stolen: Please deactivate my account” to help you out.
Also, you can contact WhatsApp to assist you either by opening WhatsApp > Settings > Help > Contact Us or sending your question via the website.
WhatsApp Group Chats
While you enjoy talking with group chats of friends and family members, some people out there might have their hungry curiosity been fulfilled by tracking your group messages through some tricks. The end-to-end encryption of WhatsApp may not help you out in keeping your group chats private. That is, groups are usually open to joining by direct invitation within the app or by creating a digital invite link that can be shared wherever possible.
As long as this link is posted publicly on the internet, it can be indexed by search engines like Google. This allows simple search words to take them out. Therefore, anyone finding a group link online can join the chat and probably invade the group information along with the members’ phone numbers and WhatsApp usernames.
Some hacking experts reveal that group chats are vulnerable to spying despite end-to-end encryption. That is, some researchers point out that a backdoor can be hacked upon the server letting anyone with access to the server, let be staff or any interfering third party, to add new members to the group without any permission and allow these invaders to obtain the encryption key. Therefore, a masked spy inserted from the server end can gain access to the keys shared by the phone of every member on the group and can now see all the decrypted messages.
Handle the issue via the group chat settings to put more control in your hands of the annoying groups invites. Go to Settings > Account > Privacy > Groups, and then decide who can add you to groups; everyone, your contacts or your contacts with exceptions.
Can a WhatsApp Group Get Hacked?
When one of the group members’ account is being hacked, hackers can be able to read messages in the group
if it happens for that person to be the admin, hacker can also able to add or remove some members and change the setting of that group.
