Smartphone security risks rise on top

If you are using a Smartphone and using the internet with different applications especially in the public networks or free Wi-Fi network then you really need to secure your phone from the crackers who can hijack your device or steal your data.

Cyber Crime Investigator & Security expert Dr. Anup Girdhar, (CEO-Sedulity Solutions) said that as more people use their mobile devices in free and open Wi-Fi networks, the risks are increasing as well. It’s time to lookout for fraudulent applications, messages and Wi-Fi networks which can trick users of mobile devices to divulge passwords, personal data or even credit card numbers.
In case you are using any Android device, then you are often targeted by spyware, including one system called FinFisher, capable of taking a mobile device, or Loozfon, "an information-stealing piece of Malware."

Dr. Girdhar said that as the popularity of apps is increasing, the chances of Cyber Crimes have also been increased. You download an application which could be malicious and designed to steal your personal information or could even send out paid text messages without your knowledge."
Some crackers are using Twitter or some other ads offering special discounts for popular gifts, which link to a malicious software. Now a days, "Criminals are more Tech Savvy with authentic-looking social ads that take consumers to legitimate looking websites.  "In order to take advantage of the best deals consumers provide their personal information including credit card number, email address, phone number, home address etc."

Dr. Girdhar has advised and appeal from all the Smartphone users to "Be careful what you do on public Wi-Fi networks especially when you're shopping”. Do not expose passwords, account numbers or credit card information unless you are certain that you are on a secure connection. "Use carefulness when downloading apps. Only download apps from legitimate sites you trust or experts suggest.

Ways of Improving Communication | Sedulity Groups

Think before speaking - This is not something new, but however often we hear it, we forget to apply it. To think before speaking means to show consideration to the other and then we say the right thing, at the right time, in the right way. 

Listen with both ears - We should be an active listener by tuning in fully and being present fully with the person and with the moment. If I am not, I listen through one ear and let it out of the other, or I only half listen, which finally creates misunderstandings.

Sedulity Groups | Your Friend can help Investigators to Access your Facebook Profile

If you’re not already particularly picky about who you friend on Facebook, you might want to think about rejiggering those privacy settings. It's not the backdoor access that the FBI has been pushing for, but US District Judge William Pauley III has now ruled that it and other law enforcement agencies are entitled to view your Facebook profile if one of your "friends" gives them permission to do so.

As GigaOm reports, a New York City federal judge ruled in a recent racketeering trial that it’s legal for police to view your Facebook profile if one of your friends grants them permission. Better start sniffing out the rats on your friends list.
That’s because all of that data that you think is personal really isn’t that personal after all, according to the Judge. "Colon’s legitimate expectation of privacy ended when he disseminated posts to his friends because those friends were free to use the information however the wanted including sharing it with the Government."

Security researcher Jonathan Brossard created a proof-of-concept hardware backdoor called Rakshasa that replaces a computer's BIOS (Basic Input Output System) and can compromise the operating system at boot time without leaving traces on the hard drive.
In short, firmware is software that is stored in non-volatile memory on a computer chip, and is used to initialise a piece of hardware’s functionality. In a PC, the BIOS is the most common example of firmware but in the case of wireless routers, a whole Linux operating system is stored in firmware.
