Always install “Find My Mobile App” in your smartphone.  Losing your cell phone can turn into a nightmare, just by thinking about all the personal and useful information going into the hands of hackers directly. But you can still locate your phone with the app installed. It is also possible to lock or remove your data completely by using this app.

Mobile Malware is at the top these days. Online Banking and Online Shopping are very common now-a-days. In 2015, the Pew Research Centre shows 57% of users do online banking, thus transmitting personal and sensitive data. Cyber criminals send fake texts or links to collect personal data. Anti-malware helps you to prevent the damage caused by any malicious download or attachment.

Re-check your Social Media security settings:

Security settings in your social networking sites i.e. Facebook, Instagram, Twitter, YouTube etc. should be set to private. Never reveal any other personal information on these platforms. You can encrypt your data in a zip file so that it doesn’t get leaked. If you want to encrypt any hard drive you can always use “BitLocker drive encryption” security.

SSL Certificate:

Always use websites with SSL certificates. Check whether they have padlocks and also check if their SSL is not expired. They are secured ones and you can trust them with your personal information. Mostly, when you pass your credentials to any website, always check the green padlock on website, it assures that the website is legitimate to handle customers’ data in encrypted form. Moreover, HTTPS and a site seal from certificate authority also assures site’s safety.

 Cyber attack numbers:

As per Lookout security report , you will be amazed at the ignorance of users and the smartness of hackers. Just view the below data:

Reason of Unawareness % of People Unaware
Unsafe link clicked 40%
Smart phone apps can pass sensitive information without user knowledge 89%
Financial apps for smart phones can be infected by malware 91%
Fail to log off properly from an app and get attacked 56%


As technology is advancing, stronger security protections for smart phones are being developed.

Samsung has invested in FIXMO firm, who is into R&D of Device Integrity Verification, Data Loss Prevention (DLP) and Risk Analytics. Let us hope that in future, AI (Artificial Intelligence) is used to curb cyber-attacks rather than doubling them and making them vulnerable.
