Instant messaging platforms that provide end-to-end encryption like WhatsApp and Telegram promise to give us rock-solid security but do they provide us full security. Some vulnerabilities that permit hackers to operate the images and audio files you receive on these platforms were exposed by researchers from cyber-security firm Symantec on Monday. Symantec researchers claimed in a blog that the security defect, dubbed “Media File Jacking”, affected Telegram for Android if certain features were enabled and WhatsApp for Android by default.
Telegram Saves files to external storage when the “Save to Gallery” feature is enabled while WhatsApp saves files to external storage automatically as claimed by the researchers. They further added that neither of the apps has any system in place to shield users from a Media File Jacking attack.
There are various ways in which attackers could exploit this vulnerability to trap victims. If the security defect is exploited, sensitive information such as personal photos and videos, corporate documents, invoices, and voice memos could be misused by a malicious attacker as claimed by the Modern OS Security, Symantec officials.
A malicious app downloaded by a user could act as a gateway for the hacker as the app could run in the background and start a “Media File Jacking attack” while the victim uses WhatsApp.
In the same way, the attackers could make audio message spoofing, payment manipulation, or spread fake news.
The new generation of Instant messaging apps is safe from privacy risks and content manipulation all thanks to the utilization of security mechanisms like end-to-end encryption. But even after the safeguarding measures the Media File Jacking threat still prevails.
A virus in WhatsApp’s audio call feature permitted hackers to install spyware onto Android and iOS phones just by calling the target as the reports in May revealed. Israeli cyber intelligence company NSO Group were the ones who developed the spyware.
The vulnerability that could allow an attacker to insert and execute code on mobile devices has been identified and promptly fixed as claimed by WhatsApp.
The Technology That Is Used In Making Footballs
Football is a game that has the most number of fans all around the world, but what most people don’t know is that this game is much older than we all know to be. Officially football started around 2nd to the 3rd BC in China. But some studies suggest that the game is a lot older than that.
However old the game may be, the rules of the game have never been that different for the time it has lasted. However, the equipment that is used to play the actual game has changed substantially over the centuries, and that is to be expected because over the year’s technology has also improved a lot thus creating new opportunities for people to use it and make better versions of the equipment itself.
Today we will be taking a look at the infamous football, how was it made and what kind of technology is used to making the footballs that are used in some of the most famous football games in the world.
The History of Football
Originally the football was a ball that was filled with feathers to provide a structure to the ball itself. Over the years the first big change that came to the ball was the introduction of air-filled balls on around 206 BC -220 AD. Now the ball was a two-part construction, the inner layer for holding air and the outer layer for strength and shape.
The outer layer was made from real leather back then which made the balls much heavier but since there wasn’t an alternative back then the people stuck with it and used the same materials and techniques till the introduction of the artificial leather. Since then almost every football is made from artificial leather on the outside and rubber bladder on the inside for capturing the air.
Since the game is so old, we have come to realize that people back then also used to bet on these matches much like people today who use websites like Bet365 to place their bets.
How Modern Footballs Are Made?
The football making and testing process have greatly improved over the centuries and FIFA footballs are made from the finest product there is to date. So let’s discuss more about that process.
The process can be broken down into 3 parts, first making the necessary parts from raw materials, assembling the footballs, testing the footballs.
The first part starts when the raw materials are brought to the factory. The bladder or the tube of the football is made by melting a specific combination of rubber and other materials and pouring them into a pre-made mold to make the form of the bladder. Once it cools down and solidifies the valve is added into the rubber bladder to complete the bladder portion of the build.
On the other hand, a trade secret recipe is used to make synthetic leather, and then it is converted into sheets. Those sheets are then used to cut out the shape of the outer layer components. A laser-guided cutting table is used which works by adding material to the table, the computer sensing it, and then making the cuts to minimize waste.
After the materials are cut and made, the assembly process starts which sews the outer shell over the bladder completing the build. Now each ball is tested using specialized digital pressure chambers to ensure its reliability. If passed the balls are good to be used.
Even though the game and its equipment have changed so much over the years, the only thing that has not changed is the enthusiasm of people betting on this sport using websites like pro-stave.com for their ultimate enjoyment.

Why More And More Solar Powered Street Lights Use Lithium Battery?
With the deepening of the new socialist rural area and the construction of beautiful villages, solar street lights have become the preferred lighting equipment. Solar street lights not only save energy and protect the environment but also generate electricity bills, so they were met by large masses of people. In the past, many solar street lights used lead-acid batteries, and now lithium batteries were used.
Why are lithium batteries so popular? What are the advantages of lithium batteries over lead-acid batteries?
- The lithium battery is small in size, lightweight and easy to carry. Compared to the lead-acid colloidal battery used in the same power solar street light, the weight is about a third and the volume is about a third. As a result, transportation is easier and transportation costs naturally decrease.
- Lithium battery has high energy density and long life. Energy density refers to the amount of energy stored in a given area or mass unit. As the battery’s energy density increases, more electricity is stored per unit weight or volume. Many factors affect the lifetime of a lithium battery, and energy density is one of the most important internal factors.
- Solar street lights are easy to install using lithium batteries. When installing a traditional solar street light, a battery pit needs to be separated and the battery is placed to be sealed in the underground box. Lithium solar street lights are much easier to install and the lithium battery can be mounted directly to the bracket using a hanging or built-in type.
- Lithium solar street lights are easy to maintain. While lithium-ion solar street lights need only be removed from the battery box or battery board during maintenance, the traditional solar street light needs to dig up the battery embedded in maintenance; this is more troublesome than lithium solar street light.
Solar Street light Installation Tips
Solar street lights require Wiring as traditional street lights that are not easy to install and do, but they also require some installation skills and precautions during installation. This makes it easier and easier to use solar street lights.
First, solar street lights should be installed on sunny days
When installing solar street light should be done on a sunny day. We know that the sun rainy day is not enough and it is not possible to complete the charge quickly after this installation. If it is discharged at night, it will not only get good results but also solar street lights will affect its service life.
Secondly, it should not be illuminated on the first day of installation
The battery is the core of solar street light. The professional recommends for the first daylight after installing solar street light to increase solar cell usage time and extend the number of charges and discharges. When we install it, you can connect the controller first, so the maximum amount of battery allowed, so that the battery can be activated better, the battery rechargeable battery charge, wake up the loaded person, so that it lit after two days. Increase usage time.
Waterproof products choose third, solar street light controller
Due to the effect of cloud and rainy weather, this controller is recommended to choose a waterproof task with a high-quality product to ensure better solar street lamp stability and thus improve its waterproof ability.
Fourth, pay attention to the angle of the battery card
The solar street light panel angle must be selected to choose the correct position. It is recommended to choose an angle of 45 degrees. Because of the angle is not suitable, it not only affects battery charging performance but also decreasing the lighting time and making the auto lighting time wrong will also affect the battery detection performance.
