Know WhatsApp security flaws and protect yourself!

Pinterest LinkedIn Tumblr

Normatively, we make use of various applications on our mobile phones and computers that are sometimes not as safe as they appear to be – not because they don’t want to, but because of their complexity they are more vulnerable to problems that pass alongside developers and development teams. . The vast majority of these problems turn out to be trivial and do not compromise the security of the application, however, some can be more serious than others.

When it comes to privacy, the vast majority of Internet users express concern about the consequences of using applications whose security flaws are evident – something that is usually very desirable for any attacker. Message exchanges can in many cases be easy targets for the intersection of private content. Increasingly, these digital communication intermediaries have sought to develop encryption systems to create closed information channels (point to point) so that only the receiver and the sender have access to messages, but what if these encryptions are not enough?

WhatsApp has become, nowadays, with the democratization of fast internet access, an ideal tool for exchanging messages, images, documents and audio files between countless users, joining messages (email style), SMS, MMS, or even attachments (which were previously only sent by email). The success of the application has more than proven and today, few mobile phones do not have this application.

What if we have a solution to learn about these problems?

Since not only privacy problems are experienced in these applications, today we present a tool for Malavida which informs users of security problems that are occurring with the WhatsApp communication network. This tool allows, among many things, to measure the security of WhatsApp, through “WhatsApp Safety”- which guarantees the consumer the number of security problems and what kind of problems in a language closer to that of a layman.

The problem database is easy and frequently updated so that you always have the information you need to protect yourself in this very complex world that can be virtualization and digital footprint. If you are free to consult the Malavida website, more precisely, the “WhatsApp Safety”You will find all the errors that have been reported since 2011 – which serves to verify the entire“ panoply ”of problems that have been potentially resolved.

Since the application is available on both iOS and Android, it is not difficult to predict the occurrence of some problems – some of which we will expose next, even more so in a network as complex as this one.

1) Malicious applications with possible access to attached content

Although this problem is a little complicated to understand, an error in the Media ContentProvider URI (resource identifier) ​​used when opening attachments in third-party applications caused them to be generated sequentially, which means that a malicious application could in theory open the file and guess the URIs of other previously opened attachment files.

It is as if we are in front of someone who makes a copy of a key that is supposed to be ours, but that is no longer. Attachments are a major source of malicious software on mobile phones, but especially on computers. Therefore, this error is nothing strange to us.

2) A library bug could corrupt memory, activate code execution and cause other bugs in the application

Sometimes, serious problems occur in very remote scenarios, but even if they are, they can happen. A set of different events managed (some time ago) to cause a failure in the memory of the application, leading to a succession of bugs and even the possibility of executing malicious code. The bug was related to a problem in a registration database (from WhatsApp) that was used in versions prior to 2.20.111 of WhatsApp Messenger and WhatsApp Business for iOS. To cause the bug, different assumptions in a certain order were necessary, including receiving an animated sticker while placing a video call on hold.

This problem seems – although in a very simple way – those attempts to send a website down by overloading information, or by DDoS attack. This bug was reported on November 5th, 2020 and is part of a very recent set of problems that have been raised to date.

3) Blocking the application when sending long messages

This time, it is not a problem that could directly compromise security, but a block when sending a very long message that has a URL (a link to a website), it was possible to block the user who did it from from an iOS device, causing the application to crash and terminate while processing the message for sending.

These are just a few examples of what you can find through WhatsApp’s protection tool from Malavida, so we invite you to take a look around the site to get to know some of this information that can be quite relevant so that you don’t fall into the same problems that others had the opportunity to fall into and share with the community.
