How a Single SMS can Break the Security Defence of Android phone

You may be surprised to know that in 2017 also Android devices are being compromised by boobytrapped SMS text messages. Attackers are able to uncover the flaws in Android phones. Remote attackers are exploiting Android smartphones to execute attacks and endlessly reboot targeted devices. Vulnerability researchers and Android security experts have found that hackers and attackers are able to trade on security holes and exploiting targeted devices with minimum (or no) user interaction via WAP configuration messages.

Attackers use different approaches to attack on an Android phone and this problem gets more critical if users accept malicious messages blindly without checking their content and origin. There are plenty of malicious apps and bugs which can do irreparable harm to mobile devices. Even a sinle text message that seems innocuous, but carry infection may wreck your Android phone’s security. If you receive a text message from an unknown source which looks like a multimedia message includes a link and, country code, number of sender, and other content, don’t open that link.

Malware and such other infection writers create and implement such codes that they can bypass all security measures and attack specific users in order to achieve specific outcomes like stealing money or making money using unfair means and approaches. Hackers know that banking malware is big business so they are targeting more and more users who use online banking through their malware mercenaries more than ever. Once malware authors and distributors trick you into downloading malicious app onto your smartphone they exploit the vulnerability to get the control of your device.

So if you get any messages from any unknown contact, don’t click on it. If you will open this link, it will install an app that will give access to the hacker to steal the sensitive information from your mobile device. They can use their own installed app as backdoors to spy on you and break the applied security protocols and furthermore get the details of your online banking apps as well as credentials of other websites also.

To avoid being victim of such attacks, NEVER click on links in SMS or MMS messages that you receive on your mobile phone. Android phones as well as other platforms are notoriously vulnerable. There are many security products dedicated to this platform which perform effectively for the security of Android devices. If in case you think that you have clicked on a link inadvertently, change passwords to all your services and ask a security expert to reflash your phone.

Verify data is encrypted

Encrypt all the confidential information that you are sharing and transferring over the internet. Encrypt information such as credit card numbers, usernames, or passwords and send it securely. To verify this, look for Internet browser security lock (a small lock) next to the address bar or in the bottom right corner of your browser window. Once you are able to see this, makes sure that it should be in the locked position. Also make sure that the URL begins with https.

Data is encrypted if the lock is in the locked position. No one can intercept the data if try to intercept it if the data is locked. All information can be read if there is no lock visible and once it is intercepted. Use a password that you don’t use with protected sites if a web page such as online forum is not secure.

Use a safe and strong password

You should use strong and safe passwords for those websites which store confidential data. It is advised to you that use a different and strong password for each website that requires a login. Use a password manager if you cannot remember your passwords.

If available, enable two-factor authentication

If you enable two-factor authentication, you add an additional step for your online protection while verifying a login. Typically with two-factor authentication, after entering password, if the service does not recognize your device, you will receive a text message with a specific code to login. It is a good way of protection because no one can access your account even though one has a valid password because it requires that specific code to login.

E-mail is not encrypted

Never transmit you highly confidential data like your credit card information, passwords, and bank details over e-mail is not encrypted and any intruder may hack and read it.

Be careful while accepting or agreeing to prompts

Read and understand the agreement before clicking on the Ok button while installing any program. Cancel or close the window if you do not understand the agreement or feel that it is not necessary to install the program.

Additionally, check out for any check box that asks if it’s ok to install a third-party program, toolbar, etc. If it asks so, leave these boxes unchecked or cancel the install as these third-party programs causes more issues than good.

Be aware of phishing scams

Be aware of different types of phishing scams and techniques, which are meant to trick innocent users into providing their account information.

Stay concerned where you’re logging in from

Business: Your place of work can install key loggers or use various ways of monitoring you system when you are online. Someone who has access to this information may be able reading and recording this information. So it is recommended to you that don’t store any password in your browser if your system is shared with co-workers.

Wireless network: Your computer can be intercepted and read by someone else who is nearby when you are on a wireless network. Log onto a secure network using WEP or WPA to prevent this from happening. If you are on a home network. Make sure that it secure.

Friend’s house: Be careful if logging into an account on a friend’s computer because a computer or network you are not familiar with could unintentionally or intentionally log usernames and passwords. Never save the password information on the browser if you are logging into any site on a friend’s computer.

Use the latest browser

An outdated browser is highly insecure so use the latest version of the browser like use Microsoft Edge instead of Internet Explorer and also use alternative browser such as Google Chrome or Mozilla Firefox to stay safe.

Be attentive of those around you

Be careful of anyone’s shoulder surfing at work, school, library, or anywhere else. At such places, people may watch you filling up your confidential information like login ids and passwords. To keep your information private that display on the screen, use privacy filter for the display.

Update Internet browser plugins

Make sure all installed Internet plug-ins like Adobe Flash are up-to-date as often attackers find out security vulnerabilities through browser plugins.

Secure saved passwords

Always store passwords and login information in a secure area. Never write login information in a text file that is not encrypted or on a sticky note. Use a password manager to keep your login information secure.

Have against malware, spyware, and viruses

Give the complete protection to your device by installing an anti-virus program on it. Software programs like Trend Micro, Norton, Avira, etc. can keep your computer safe against malware, viruses, and other such infections.

If in case you don’t want to install anti-virus protection and running the latest version of Windows, run at least Windows Defender on your computer.

High Popularity is the Menace for Android

Android is one of the most popular platforms which acquire more than 80 percent market share whereas iOS has a market share in the teens and rest is distributed among other smartphones operating platforms. With every new smartphone launching in the market is stretching more and more share that is why Android phones rule. One of the major reasons of Android popularity is Google’s decision to make it an open OS, but this also makes this platform vulnerable to attacks.

As Android is an open OS, it allows many manufacturers to make devices that can run Android. However, when so many venders are there to use and release it in several models, it leads to OS fragmentation and results in thousands of active version of Android. Tough it is not a big deal if the vulnerabilities of each version of software are patched as soon as they come to notice. Actual problem starts when Google, a smartphone manufacturer, or an OEM is not able to release the patch on time.

Android

Attackers have taken notice that most of the times there is a delay in releasing the security patches so they trade on such delays and mange to attack on the vulnerabilities of an Android device. Hackers and attackers may put malware in the Google play store to exploit these vulnerabilities. Google uses a tool called Bouncer to scan apps before allowing them to be listed and sold through the Google Play store, but attackers do this by obfuscating infectious contents of their apps to slip past Bouncer.

Using a dropper is another way to get malware past Bouncer security scans. A dropper attack initiates when the attacker uploading an app to Google Play that doesn’t have malware. Once the victim downloads and installs the dropper app, it communicates with the attacker’s server to downlaod malware and other infections to the user’s device. One more case in point for Android devices that security researchers recently analyzed is “Charger” ransomware. Researchers found that Charger is embedded in an app, which is available through Google Play. Once Charger infected the app, it steals SMS messages and contacts from user’s device and asks for admin permissions. Once you give it permission, the ransomware locks down your device and send you a message demanding payment.

Attackers are not using only these three ways to attack Android user’s devices, but they are also using malware for Android in more dangerous ways. Attackers are putting redundant components in malware to make their attacks successful. To execute their attacks successfully, the second component keeps attacking if in case security disables one component. Camouflaging malware to look like a legitimate, hiding the app’s icon, delay to run a program when malware runs, and using social engineering to get elevated privileges in order to stop users from uninstalling the app are other persistent threats that deter user from getting rid of malware..

An alarm should go off in your head if your organization’s employees connect their Android devices to your network services like email and VPNs. To prevent users’ mobile phones from becoming an entryway for hacking and attacking attempts in your organization, make sure that you have mobile security controls in place.
