Tips to protect small companies from Cyber attack.

Are you the owner of a small company? If the answer is yes and you think no cyber attack will ever affect you, think again. In fact, there’s a higher risk of getting into trouble with hackers than if you were a big business, or even a medium-sized one. According to recent reports, more than 40% of cyber attacks are aimed at companies who employ under 500 people. A more worrisome study says that one in five small businesses are targeted by hackers. More often than not, these companies have to close down because their security plans are nonexistent or there’s too few of them to actually ensure complete protection.
Cybersecurity is the most important way to make sure your business isn’t put in danger by malware attacks. Especially when the people behind them show no signs of backing down. Thus, putting strong security measures in place is, like we said, essential if you don’t want to lose your life’s work and your clients’ trust. After all, the latter expect their sensitive data to be protected at all cost. When they see that that’s not the case, your clients will turn to other companies instead.
To prevent that from happening, we want to tell you how to protect your small company from cyber attacks.

Create as many backups as possible

A backup is incredibly important if you want to keep each sensitive data safe from cyber threats. People who create malicious software and send it to damage devices, particularly the ones used by employees from a small business, are relentless. By creating several backups, you can sleep well at night knowing that those important files, presentations, and whatnot won’t be ruined forever in case malware reaches them.

Use the most powerful antivirus software

In this day and age, relying on a strong security solution marks the difference between keeping your company o the course or shutting it down completely. Remember to choose the one made to protect a computer from every type of malware ever created. The antivirus software you end up with needs to locate and then get you rid of spam, spyware, Trojan horses, phishing attempts, and so much more. After you settle on the best option for your business, ensure that regular updates are performed.

Educate your employees

The people who work for you need to know that clicking on random links received via their work email is a no-no. It’s the same if they connect to networks that don’t use a strong password. These are only two of the most dangerous practices you must stop from happening. How can it be done? You could, for example, organize trainings or set up meetings where security professionals advise employees on safe practices at work.
Another idea would be to carry security policies and procedures through.

Payment terminals should use different networks

Using the same network for a payment terminal is a practice that should be stopped. Never ever tie it to your general store network. Instead, keep these two separate, because that way only a few authorized employees will have access to them. By doing that, the computers on your network will keep their sensitive content intact in the face of cyber attacks.

Use cybersecurity insurance

We insure our cars, houses, and so on, so why shouldn’t we do the same for our business? Cyber security insurance helps a lot in case of a cyber threat. How? If a malware attack happens, your company will be held responsible. A lawsuit will follow, so you’ll have to pay quite a lot of money as compensation. With a cyber security insurance at hand, you make sure every legal cost is fully covered.

Change passwords regularly

Many of us use the same password for more than a year on all our devices, social platforms, and so on. Employees in small companies do the same, hence a higher risk of cyber attacks. Change the passwords every three months and remember to create very strong ones each time you do that. The most secure passwords are made of 8-16 characters that contain special characters, numbers, and letters. If you know you don’t have a good memory, a password manager will make things easier for you.

'Flick' New Unit Of time invented by Facebook


We don't have the time to dig into all the different ways someone could measure time. Generally, we structure our lives around years, months, days, hours ... you know, the big ones. The easy ones. But time measurements can get as nitty gritty as you need them to. In Facebook's case, the company needed a unit of time that just wasn't there. So they invented an entirely new one.
         
Allow us to introduce you to the "flick," the new unit of time developed by a Facebook engineer. Chances are, you won't be measuring how long you've been on the treadmill or how long to cook your turkey in flicks. But for a select group, the new unit could become quite helpful. Initially created by Christopher Horvath in late 2016 and launched by Facebook Open Source in January 2018, the flick is equal to precisely one 705,600,000th of a second. It's just a tad longer than a nanosecond, but still shorter than a microsecond. Finally, right?
Like we said, understanding the flick probably won't impact your daily life. But here's a hint as to how this little sliver of a second could be helpful for some. Here are some numbers into which 1/705,600,000 divides evenly: 1/8, 1/16, 1/22.05, 1/24, 1/25, 1/30, 1/32, 1/44.1, 1/48, 1/50, 1/60, 1/90, 1/100, 1/120.
Still confused? All of these numbers are also frame rates or frequencies involved in displaying movies, music, and other media. Working any of those figures out into decimals yields a nasty, often neverending line of digits. The flick is here to clean it up. For example, 1/24th of a second is 29,400,000 flicks. If we were to try to measure that fraction of a second as a decimal, it would be 0.0416666666666666... Ew.

One Character message can even Crash an iPhone. Must Read.!

Only a single character can crash your iPhone and block access to the Messaging app in iOS as well as popular apps like WhatsApp, Facebook Messenger, Outlook for iOS, and Gmail.

First spotted. by Italian Blog Mobile World, a potentially new severe bug affects not only iPhones but also a wide range of Apple devices, including iPads, Macs and even Watch OS devices running the latest versions of their operating software.

Like previous 'text bomb' bug, the new flaw can easily be exploited by anyone, requiring users to send only a single character from Telugu—a native Indian language spoken by about 70 million people in the country.
Once the recipient receives a simple message containing the symbol or typed that symbol into the text editor, the character immediately instigates crashes on iPhones, iPads, Macs, Apple Watches and Apple TVs running Apple's iOS Springboard.

Apps that receive the text bomb tries to load the character, but fails and refuses to function properly until the character is removed—which usually can be done by deleting the entire conversation.
iphone-crash-telugu-character

The easiest way to delete the offending message is by asking someone else to send a message to the app that is crashing due to the text bomb. This would allow you to jump directly into the notification and delete the entire thread containing the character.

The character can disable third-party apps like iMessage, Slack, Facebook Messenger, WhatsApp, Gmail, and Outlook for iOS, as well as Safari and Messages for the macOS versions.

Telegram and Skype users appear to be unaffected by the text bomb bug.

Apple was made aware of the text bomb bug at least three days ago, and the company plans to address the issue in an iOS update soon before the release of iOS 11.3 this spring.

The public beta version of iOS 11.3 is unaffected.

Since so many apps are affected by the new text bomb, bad people can use the bug to target Apple users via email or messaging or to create mass chaos by spamming the character across an open social platform.

Zero Day Vulnerability in Telegram







During the analysis, Kaspersky researchers found several scenarios of zero-day exploitation in the wild by threat actors. Primarily, the flaw was actively exploited to deliver cryptocurrency mining malware, which uses the victim's PC computing power to mine different types of cryptocurrency including Monero, Zcash, Fantomcoin, and others.

While analyzing the servers of malicious actors, the researchers also found archives containing a Telegram's local cache that had been stolen from victims.
In another case, cybercriminals successfully exploited the vulnerability to install a backdoor trojan that used the Telegram API as a command and control protocol, allowing hackers to gain remote access to the victim’s computer.

"After installation, it started to operate in a silent mode, which allowed the threat actor to remain unnoticed in the network and execute different commands including the further installation of spyware tools," the firm added.

Firsh believes the zero-day vulnerability was exploited only by Russian cybercriminals, as "all the exploitation cases that [the researchers] detected occurring in Russia," and a lot of artifacts pointed towards Russian cybercriminals.

The best way to protect yourself from such attacks is not to download or open files from unknown or untrusted sources.

The security firm also recommended users to avoid sharing any sensitive personal information in messaging apps and make sure to have a good antivirus software from reliable company installed on your system

9 Unknown Facts About SpaceX Rocket Launched


Before Tuesday's test launch of SpaceX's Falcon Heavy rocket, not even the company's CEO Elon Musk knew what to expect.
"It's either going to be an exciting success or an exciting failure," he said. "One big boom! I'd say tune in, it's going to be worth your time."
Musk was right: There was a big boom when the Falcon Heavy's 27 engines fired and lifted SpaceX's largest rocket into space. The booster rockets returned to Earth, landing at the same time like a pair of synchronized divers at the Olympics. The payload, a Tesla Roadster, made it to Mars orbit and beyond.
The launch felt part scientific breakthrough, part Silicon Valley product launch. It was filled with wonder, disbelief and humor -- there's a car traveling through space with a sign saying "Don't Panic!"
The Falcon Heavy launch had a number of significant moments that were easy to miss. So I gathered all the notable instances and SpaceX Easter eggs here together.

This rocket is kind of a big deal

SpaceX has launched rockets before, but the Falcon Heavy is the company's largest one to date. Tuesday's launch was the first attempt at sending it with a payload into space.
In a press conference post-launch, Elon Musk said, "Crazy things can come true. I didn't really think this would work. When I see the rocket liftoff, I see a thousand things that could not work. And it's amazing when they do."
SpaceX has embraced the ups and downs that come with pushing rocket technology forward. Last year, the company posted this video, titled "How Not to Land an Orbital Rocket Booster," on its YouTube channel. It's basically a highlight reel of rocket booster failures -- aka lots of explosions.

The Falcon's name

 

SpaceX's Falcon 9 and Falcon Heavy rockets are named after Han Solo's ride in Star Wars, the Millennium Falcon.

It's big

At 230 feet (70 meters) tall, the Falcon Heavy is without a doubt impressive, but it's not the largest rocket ever. That distinction goes to NASA's Saturn V rocket, which stood 330 feet (111 meters) tall.

 

Designed to be reusable

An early goal for SpaceX was the development of a system of reusable rockets. For decades one of the largest cost factors behind rockets was that they had to be built anew for each launch. Musk compared it to if airplanes had to be discarded after one flight.
SpaceX focused on how to return its rockets to Earth and make a controlled landing. Last year, SpaceX did just that when the company landed a Falcon 9 booster onto a drone ship floating in the Atlantic. The drone ship's name is "Of Course I Still Love You," in tribute to the late sci-fi author Iain M. Banks.
Including that first landing, SpaceX has landed 21 Falcon 9 boosters back on Earth.

 

Three rockets

Last year's Falcon 9 had one booster rocket, while the Falcon Heavy has three: two first-stage boosters (aka Falcon 9 rockets) and one core booster. These three rockets give the Falcon Heavy 5 million pounds (2.3 million kg) of thrust, which allows it to carry 70 tons (63.5 metric tonnes) of cargo into space.
falcon-heavy2
Both of the Falcon Heavy's first stage boosters returned and landed safely in the SpaceX landing zone. SpaceX
One of the best moments from the Falcon Heavy launch was when the two first-stage boosters landed in sync back to Earth at a landing zone. It seemed unreal. The third booster, the core booster, did not land successfully and crashed at 300 mph (480 kph) into the landing drone ship in the ocean.

 

It can carry whales

The Falcon Heavy can carry a 140,700-pound (63,800-kg) payload into lower Earth orbit -- that's the equivalent of two humpback whales. For a trip to Mars, it can carry 37,000 lbs (16,800 kg) -- about the weight of 31 grand pianos.

 

The rocket car

When a new rocket is tested, the payload is usually a concrete block. Typically, Musk thought that was boring and opted for a cherry-red Tesla Roadster with a dummy astronaut named Starman (after the David Bowie song) in the driver's seat.
"It looks so ridiculous and impossible. You can tell it's real because it looks so fake. We'd have way better CGI if it was fake," said Musk. "The imagery of it is something that's going to get people excited about it around the world."

 

A brand new spacesuit

The spacesuit Starman wears is actually one Space X revealed last summer. It looks sleek and futuristic with its gray and white color scheme and was tested to double vacuum pressure.

 

Tesla Roadster Easter eggs

The car itself had a handful of Easter eggs:
  • On the dashboard sits a tiny Roadster and spaceman
  • The dashboard's screen displays "Don't Panic!" a reference to the cover of the guide in the novel "The Hitchhiker's Guide to the Galaxy" by Douglas Adams
  • "Made on Earth by humans" is printed on the car's circuit board
  • In the car is a disk with a digital copy of Isaac Asimov's Foundation series of sci-fi books
  • There's a plaque in the car engraved with the names of 6,000 SpaceX employees

What are Proxy Servers and Types of Proxy Servers..?



Proxy servers are servers that takes the request from normal machines and IP's and forward there request of the page that are requested by normal machine to the Internet and when the internet sends gives response the page that is requested by the proxy server that response is send back to the normal machines and IP's . there are varieties and types of Proxy Servers some of them are as follows:- 
  
Transparent Proxy – This type of proxy server identifies itself as a proxy server and also makes the original IP address available through the http headers. These are generally used for their ability to cache websites and do not effectively provide any anonymity to those who use them. However, the use of a transparent proxy will get you around simple IP bans. They are transparent in the terms that your IP address is exposed, not transparent in the terms that you do not know that you are using it (your system is not specifically configured to use it.) This type of proxy server does not hide your IP address.

* Anonymous Proxy – This type of proxy server identifies itself as a proxy server, but does not make the original IP address available. This type of proxy server is detectable, but provides reasonable anonymity for most users. This type of proxy server will hide your IP address.

* Distorting Proxy – This type of proxy server identifies itself as a proxy server, but make an incorrect original IP address available through the http headers. This type of proxy server will hide your IP address.

* High Anonymity Proxy – This type of proxy server does not identify itself as a proxy server and does not make available the original IP address. This type of proxy server will hide your IP address.

How Google Search Works..?


Now a days Internet has become a comman term among people and in it Google is one of the most widely used searched engine. So now some people What really a Search Engine is..?  So Search Engine is basically a program or tools by which we are able to search anything on the Internet. There are many types of search engines available like... Google search, Yahoo Search, Bing, Duck Duck Go etc.. in them the Google is mostly used.
           So now the question arises How Does a Google Search  Works..? When you search anything on Google let us suppose you typed 'techtalksgroup'.
       Basically it works in many stages, the first stage includes of   
  • Crawling . Crawling is a method of fetching a web page that contains the keyword that you types to search. For example i told you that if i search techtalksgroup on google it will find everywhere on the web where the word techtalksgroup is located and it will collect it all. Now the next stage is of managing the web page in particular order.
  • Indexing.  Now under Indexing stage it will arrange the pages collected in a sequence like  the most searched page will be indexed first and , the pages which exactly matches with the keyword will indexed first etc.. Now the third stage is of just serving the page what you typed.
  • Serving.  Now serving comprises of showing the pages and links infront of you what you have searched for.. So there is basically an AI based algorithm know as Page rank. PageRank is the measure of the importance of a page based on the incoming links from other pages. In simple terms, each link to a page on your site from another site adds to your site's PageRank. 
thats it guys...
