Can You Hack Someone Whatsapp

Can You Hack Someone Whatsapp – Imagine that someone has taken over your account, what will happen to you and the people you interact with on WhatsApp?

Just as it is easy to install a new WhatsApp for your new phone, it is also easy for an attacker to gain access to your WhatsApp and possibly start a conversation with your friends pretending to be you.

Can You Hack Someone Whatsapp

Often the immediate danger is not to you if someone attacks you, but to your connections. They can expect to receive requests for data or even emergency funds. This is social engineering at its best. We would trust an end-to-end encrypted platform, a message from a trusted friend and coded so as to let our guards down and feel compassion instead in these situations.

The effects of this happen beyond imagination. It can even spread to more than your contacts if WhatsApp accounts are taken over.

Once the account is taken over, attackers can send messages to contacts in groups you belong to as if the account owner (you), as well as any other contacts whose WhatsApp messages were received after the takeover

No legacy data is compromised. The target device remains untouched. WhatsApp is ghost on an illegal device.

It’s surprising how many people haven’t enabled two-step verification PIN on WhatsApp – almost everyone we asked hasn’t set it up yet. If you are the same, take this moment and install it today.

Whatsapp: Popular Free Messaging Service Puts Users At Risk

The question now is, how can we prevent this from happening to you the first time or again?

WhatsApp has introduced a feature where you can set a PIN of your choice and even an email address if you forget your PIN. The PIN is your own authentication to verify that you are even after entering the SMS authentication, so you don’t have to share your PIN with anyone.

You can find this feature in your WhatsApp settings > Account > Two-step verification: there you will be prompted to give your PIN and confirm it, and you will also be asked to enter an email address that will be used to restore your Account in if you forgot your PIN In a briefing session at the annual Black Hat security conference in Las Vegas on August 7, researchers from the Israeli security company Check Point revealed how WhatsApp – owned by Facebook – can be hacked to change the text of The message and the identity of the sender. If that’s enough concern, these vulnerabilities were discovered in WhatsApp last year but can be exploited today.

In a presentation titled “Reverse Engineering WhatsApp Encryption for Chat Manipulation and More,” Roman Zaikin, security researcher, and Odd Vanunu, head of product vulnerability research, both at Check Point, explained the process in detail.

The story, however, begins in 2018 when Vanunu, Zaikin and another researcher named Dikla Barda successfully reverse-engineered the WhatsApp web source code and decrypted WhatsApp traffic. While developing an extension to Burp Suite, a web application testing tool, using the web functions they found, to help find vulnerabilities in WhatsApp, perhaps not surprisingly, the researchers found a number of weaknesses.

The Check Point team has identified three possible attack methods, all of which use social engineering tricks to trick end users and all of which give an attacker the necessary tools to intercept and manipulate WhatsApp messages.

“At the end of 2018, Check Point Research notified WhatsApp of new vulnerabilities in the popular messaging application,” the researchers explained, “which give attackers the power to create and spread false information from users who seem to trust the device.”

On August 7, WhatsApp just installed the first of the list. There is a clear potential here for online scams, rumors and fake news due to the nature of the remaining two. Check Point said that “threat actors have an additional weapon in their arsenal to use the messaging platform for their malicious intentions.”

This is despite the fact that Check Point informed WhatsApp about its findings in the name of responsible disclosure, and highlighted the vulnerabilities as “most important and requiring attention.” Check Point even created a tool to exploit vulnerabilities, decrypting WhatsApp communications and forging messages, through a proof of concept to demonstrate the seriousness of the situation.

It appears that WhatsApp has chosen to leave more than 1.5 billion users in over 180 countries vulnerable to potential attacks by actors using these methods.

Oded Vanunu, Head of Product Vulnerability Research at Check Point, and one of the team that discovered the WhatsApp vulnerabilities explained the reason for the submission to Black Hat. “Instant messaging is an important technology that serves us every day, we conduct our private and professional lives on this platform and it is our duty in the infosec industry to be alert to situations that may question integrity,” he said Vanunu. “WhatsApp is very responsive,” he continued, “but it took a few actions, including confirming one of the manipulation scenarios. Therefore, we decided to share the technical information and situations during Black Hat USA 19 to raise awareness.”

“We carefully reviewed this issue a year ago and incorrectly suggested that there was a security vulnerability that we provide in WhatsApp,” said a Facebook spokesperson, “The scenario described here corresponds to changing replies in mobile email to do . Look like something that no one has written. We have to remember that the treatment of the concerns raised by the researchers could make WhatsApp more private, such as storing information about the source of the messages.

Although I appreciate that privacy is a major consideration for WhatsApp users, I am not convinced that these users would consider the risk of their messages being intercepted and change a privacy plus point.

Facebook is in a tough spot with WhatsApp here, but no one said running a secure and private messaging service would be easy. The privacy paradox was highlighted in a previous report on how the merger of WhatsApp and Facebook Messenger could work.

“This is a very serious issue that has not yet been addressed,” said Stuart Peck, Director of Cyber ​​Security Strategy at ZeroDayLab, “The integrity of messages received from trusted sources is essential if users are to trust the encryption of messaging services like WhatsApp. “

Peck said he was actually surprised Facebook hadn’t addressed the vulnerabilities because of its history of trusting its users who were abused by the Cambridge Analytica scandal. “This plays into the hands of attackers,” Peck continued. “The ability to use the ‘quote’ function in a group chat to change the identity of the sender worries me the most.”

Which is understandable, because it could potentially be used to carry out what Peck describes as “totally destructive tricks used to manipulate or abuse people’s trust.” If an attacker wants to gain access to work systems for a purpose, collecting mobile phone numbers through Open Source Intelligence, it is possible to insert himself into a conversation and manipulate both sides of the conversation in time to reveal sensitive information.

Such “spoofing” on WhatsApp is more dangerous than its email equivalent, according to Peck, because the basic integrity checking mechanism in this attack is bypassed, with no existing means of notifying the recipient that it is misleading. “Facebook must address this or risk exposing their users to more attacks,” he warned, adding that “if Facebook does not address this vulnerability, users should consider switching to a mutually encrypted messaging service like Signal.” , financial and political developments around the world.
