movavi photo editor

When it comes to photo editing software there is absolutely no shortage of options available in the event you use the Windows operating system. Basically everyone knows Adobe’s suite and other options that are available. The problem with most of them is simple: price. Professional photo editing software costs a lot of money. Most people do not have the money that is needed to cover the price of the program. Then, besides the program, you also need to make payments for extras that would be used as you edit photographs.

Movavi Photo Editor for Windows computers (free trial can be downloaded here: https://www.movavi.com/photosuite-download/) tries to solve the problems identified above by offering a product that is very simple to use and intended for the regular user at a price that is highly affordable. Basically, this is software intended for the person that never edited a photograph before and that wants to do so just like the professionals do.

Much can be said about Movavi’s software but some facts of high interest for most potential users are presented below.

Modifying Individual Appearance In Photographs

Did you ever take a picture in which you really like how you look but there are some skin imperfections that you would not want to share with others? Movavi Photo Editor can spot-treat them, remove face shine and then make everything more attractive by evening out skin color. You can add lip tint, add some eye shadow, a great mascara and make your teeth look as if you recently got some whitening done. Simply put, you can modify your appearance in your photos in just a few minutes by using tools that are especially created for this purpose.

Perfect Use Of Filters

Ever since Instagram started to offer filters, this became an industry standard. Filters are needed in most photo editing tasks and that is also true when looking at the regular user. When you add a filter to an image you can make it special. Movavi realized this and made filters a huge part of the Photo Editor. You have access to dozens of great filters that can be applied and modified only with a few clicks. Get that glow you wanted in the picture you took!

Removing Unwanted Elements

Sometimes you just want to take something out of a photo or take yourself and move to another background. Photo Editor allows this with some specific tools that are really easy to use and have a highly intuitive interface. Remove the wine from the table or cut the large rock that blocks part of the view straight from the program.

Final Thoughts

The features that were mentioned above clearly highlight why Movavi Photo Editor is gaining such popularity among users in such a short time. All this and so much more is available for under $30, which is so much less expensive than the professional alternatives while being able to offer professional results for most of the tasks that the regular user would want to do during photo editing.

Inside the New WhatsApp Buffer Overflow Vulnerability

Published

on

Whatsapp

Facebook’s WhatsApp mobile app has had a rough time lately with regard to software vulnerabilities. In November 2019, the social media company quietly issued a security patch for a buffer overflow vulnerability contained in their messaging application.

However, the vulnerability disclosed in November 2019 is not the only recent vulnerability discovered and patched in the secure messaging application. Earlier in 2019, another buffer overflow vulnerability was discovered and patched by the company. Both of these vulnerabilities are rated as “severe” due to the fact that an attacker exploiting them can run malicious code on the target device.

To make things worse, the vulnerabilities in WhatsApp can be exploited by an unauthenticated attacker. These vulnerabilities were discovered in functions that process data sent by another WhatsApp user to the target. By taking a simple action – initiating a WhatsApp call or sending an MP4 video to the target – an attacker can trigger the vulnerability, giving them control over the device. These vulnerabilities can then be exploited to place spyware on the victim’s device and to view the user’s messaging history within the app.

A Brief History of WhatsApp Security

The recent WhatsApp vulnerability is not the first buffer overflow contained within the mobile app. In May 2019, a different buffer overflow vulnerability was discovered in how WhatsApp processed the data contained within an incoming call.

This vulnerability was created because WhatsApp uses a special binary format for sending data between devices and then unpacks this data at the recipient device. If an attacker sent a specially formatted packet, which lied about the length of a certain field, the recipient’s WhatsApp would unpack the data into a place on the stack that did not have sufficient space for it. As a result, the attacker would have the ability to write to memory that should have been outside of their control. This vulnerability was concerning since it allowed remote code execution on a target device without any user interaction required. The malicious packet was sent as part of initiating a call, so, even if the user rejected the call, the damage was already done.

This past WhatsApp vulnerability has been the source of significant controversy. While Facebook was in the process of patching the vulnerability, they observed someone trying to exploit it on the device of a UK-based human rights lawyer. Additional investigation pointed to the use of the vulnerability to spy upon individuals who would be of interest to certain governments.

The Israeli-based NSO Group is well known for developing and selling exploits to governments for use in surveillance activities that fall outside the scope of law enforcement activities. This, and the fact that the observed attack used infrastructure previously linked to the NSO Group, has led Facebook to believe that the company was beyond the exploitation of the WhatsApp vulnerability. As a result, Facebook has begun a lawsuit against the NSO Group for exploitation of a vulnerability in one of their products.

The Newest WhatsApp Vulnerability

The buffer overflow vulnerability disclosed in May was not the last such vulnerability in the WhatsApp platform. In November 2019, Facebook patched another vulnerability in WhatsApp that was similar in scope, severity, and potential impact.

This vulnerability dealt with how WhatsApp handled MP4 video files. Along with a video file comes a stream of metadata containing details about the file. When parsing this metadata, WhatsApp is vulnerable to a stack-based buffer overflow attack. This would allow the attacker to perform a Denial of Service attack (crashing the app) or to run attacker-controlled code on the app that could give access to previous conversations that the user has performed on the app. Exploitation of the vulnerability only requires an attacker to know the phone number of the victim and to send them a malicious MP4 video via WhatsApp.

Luckily, while the new vulnerability had the potential to be at least as damaging as the previous buffer overflow flaw, it appears that this one was not being actively exploited by attackers prior to being patched by Facebook. However, this demonstrates the importance of keeping such applications up-to-date (so that Facebook-provided security patches are applied) and to consider the risks associated with using these applications for personal communications.

Protecting Against Buffer Overflow Vulnerabilities

Buffer overflow vulnerabilities are nothing new. They are extremely simple vulnerabilities – only involving a failure to properly manage memory and user input – yet they can be extremely difficult to detect. A wide range of buffer overflow vulnerabilities exist, and sometimes apparently “safe” code can be vulnerable since another vulnerability can be exploited to bypass existing protections against buffer overflows.

The two major WhatsApp vulnerabilities disclosed and patched in 2019 demonstrate the potential impact of a buffer overflow vulnerability in a critical application. Both of these vulnerabilities could be exploited without user interaction, and enabled an attacker to run malicious code within the victim application. In one case, the vulnerability was exploited multiple times to spy upon parties of interest to various governments, leading to a lawsuit by Facebook against the suspected perpetrator.

Protecting against buffer overflow vulnerabilities requires the ability to identify and block potential exploits before they reach a vulnerable application. Deploying a strong web application firewall (WAF) to protect an organization’s web presence and runtime application self-protection (RASP) for critical or potentially vulnerable assets is an important first step toward protecting an organization and its software assets against exploitation.

3 2020 Developments That Could Make Your Life Easier

Published

on

There are many systems under development right now that could eventually make your life easier – but below, we’re going to look at 3 of them. We could be using these developments a lot sooner than you think! 

5G

Why do we need 5G when we have 4G – 4G is fast enough, right? People are worried about the health implications, but everybody seems willing to look past that to get more speed. More speed could really help businesses. Also, while 5G is generally operating from the same infrastructure as before, mass adoption will cause issues for data centers. This could make the situation both better and worse in some respects. 

Virtual Reality 

Virtual reality is already being used by many people, but it could actually be put to good use soon. When it comes to simple things like shopping, you could make your life so much easier and more enjoyable. Whether you’re shopping for furniture or clothes, virtual reality could mean checking out the fit easily. Try on clothes in the comfort of your home without even ordering them first. See what a sofa looks like before you buy. The options are endless! 

Artificial Intelligence 

We’re still going to need human intelligence, but AI can have a huge impact in our personal and working lives. In work alone it could mean enhanced automation with no need to do tedious tasks. Then, there’s next gen disaster response. It’s the technology of the future!

With these developments in mind, what are some of the most important developments in human history? Check out the infographic to find out!

Technology Advances And How We Can Embrace Them

Published

on

Smart home

When it comes to the world as we know it, there is one denying that technology has advanced at an alarming rate. So much so, that we can find that more of us are starting to see these influences being incorporated into our lives. Whether you embrace it or not. Of course, there are technophobes out there, especially the older generation, who can find the latest technology a little harder to grasp. But these advances can really help us when it comes to living our lives. Here are some of the advances and how we can embrace them each day.

Wearable technology

The changes in what we wear have become more noticeable as more of us will be wearing some form of wearable technology. It could be in the form of a watch that tracks our heart rate or exercises. It might be that some people who are older will have wearable technology to remind them to take medication or to feel safe. Such as a button that can be pressed isn they feel unwell or need some form of assistance. 

Technology on our devices

The technology that we all use personally each day has changed dramatically, we only have to look at our smartphones or laptops to see that. They are more advanced than ever before, and with that some of them can become a little more like virtual assistants. Whether that be using Apple, Android or other devices. However, we can find that there may be situations where technology can let us down, such as mac os Catalina could not be verified or we find that certain models are not updated. Another issue we can have is older technology not keeping up with the latest downloads and software updates that are required. 

The smart home

Our homes are advancing more and more, and with that it means with things like Amazon Alexa or Google Home, we have more control over what we do through our voice and commands. Whether you want to control your heating, or even things like lights, these devices in your home are making it possible with simple demands. While it may seem lazy, these devices can help to transform your home. Even enabling you to switch the heating on or lights before you arrive home, for example. 

Lifestyle changes that technology can help us embrace

Finally, technology has changed so much that we can find ourselves in a position where we are able to embrace lifestyle changes that to different technology allowing business to track things. Smartphone apps can enable us to stay on track with our spending and budgets, even do our banking online. We can then perform lifestyle changes because of the wearable technology that we can use, such as tracking exercises, the amount of calories we burn and our heart rates. 

Let’s hope this has given you an indiviation of some of the more daily technology advances we are in contact with and how we can embrace them.
