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.

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.

As Your Tech Company Expands, How Do You Scale Up Efficiently?
It is one of the ironies of business that failure can often come when your company is required to expand rapidly. For example, if suddenly you have an order for 1000 of something that you typically only make 10 of at a time, what do you do?
You have to figure out how to quickly scale up production, decide the logistics of creation, processing, and handling, and do it all while adapting your infrastructure to the new demand. With tech companies, it can be a little different because there is not necessarily a physical product. But scaling still has its own set of troubleshooting required.
For tech products, what might some of these scaling issues be? And, how do you help them? Getting bigger as a tech company may mean that you need to start using managed IT services. It also could mean that you should embrace automated advertising to get your message out to a greater number of people.
And finally, as your tech company expands, the amount of traffic to your home base will increase, which means you have to invest in a more robust web site infrastructure.
Use Managed IT Services
You can be in a tech-heavy industry and still not understand information technology services. You may know approximately how hardware and software work together, but you may never have had to set up or implement certain types of digital data transfer structures. Because of this, as your company scales upward, you may need to hire a company that works with managed IT services.
You can consult with them, and they will tell you step-by-step what sorts of actions you need to take to protect your IT infrastructure as it gets bigger.
Embrace Automated Advertising
If your business works with automated advertising on a small level, you must understand how to expand that to hit a larger or more targeted audience. As your tech company develops, you’ll get more data about who your customers are currently and who your ideal customers are going to be in the future.
There are lots of pieces of statistical data that you can gather from Google Analytics that will help you make decisions about your future promotions and advertising to make your budget use that much more efficient. You don’t want to increase your advertising dollars without increasing the sales you get from that advertising. As you scale up, you have to specify more clearly the target your automated advertising is aimed for.
Invest In a Solid Web Presence
As your products become more popular, especially in the tech world, plan to have additional traffic coming to your main website. To leverage that traffic into sales, consider hiring a website designer that creates a perfect navigational experience for potential clients and customers. There is a big difference in sales simply because a brand is willing to spend the money on creating a professional website versus one that keeps a more amateur status online.
