Running on over 80 percent of smartphones and tablets in the world, Google’s Android is the number one mobile operating system. The Android operating system is open and flexible, which makes it awesome — for users and developers alike — in so many ways. But the OS’s openness and flexibility also leave the system vulnerable to invasion by malware. Malware can be used to compromise the security and privacy of your Android device.

Protect android

In most cases, malware in Android smartphones and tablets appears in the form of an application. Sometimes, an app includes malicious codes that make it perform certain actions without your consent. For instance, some applications broadcast your location data when you are searching for local maps. But malware is not the only threat when it comes to the security and privacy of your Android device. The operating system is under constant attack and older versions are more vulnerable than new ones.

Is there something that Android users can do to secure their devices? Yes. Plenty, actually. In this article, we explore various ways you can protect your Android device from a wide range of threats out there. Read on to find out more.

Use VPN

VPN is short for Virtual Private Network. A VPN service encrypts your internet connection and is arguably the best privacy tool for securing your Android device when you are connected to the internet. creates a virtual network of any number of connected devices online thus concealing the IP addresses of devices on the network. Android VPNs optimized for the OS are rapidly growing in popularity among Android users.

Since the internet has become such a huge part of our lives, we need to ensure that we are fully protected when we go online. Android VPN is one of the best ways to protect yourself from hackers and snoopers as you go about your business online.

Enable Two-Factor Authentication

Two-factor authentication may seem like an inconvenience but it’s one of the most effective ways to lock down your Google services. 2-FA requires you to verify with a unique verification code and a passcode sent via OTP every time you log in to your Google account. To enable two-factor authentication, log in to your account, go to settings, and click on ‘Using 2-step verification.’ When 2-FA is enabled, no one can access your account even if your password is hacked.

Only Install Apps from Trusted Sources

The Android operating system allows users to install apps from third-party app banks through a process known as sideloading. To be able to install applications from third-party platforms, users are required to enable ‘Install apps from Unknown Sources’ in device settings. This is not recommended. Apps downloaded from third-party app banks may contain malware. Always disable the installation of apps from unknown sources to be on the safer side. Go to Settings > Security to make sure that this feature is disabled.

The latest versions of the Android operating system do a pretty good job when it comes to securing your smartphone or tablet. However, experts maintain that it’s not enough and users ought to do more to protect their data. Just like your computer, your Android device is also susceptible to data theft. Installing antivirus software and other security apps can be useful. Popular choices include Kaspersky, Avast, Norton, McAfee, and Bitdefender. Look for features such as Automatic Scan, Malware Detection, Anti-Theft, etc.

When it comes to device security, you can never be completely safe. This is especially true for Android-powered smartphones. Hackers are constantly coming up with creative ways to compromise the security of your device and steal data. However, by following these suggestions, you can make your Android smartphone more secure.

If you are among the ones who consider malware, worms, viruses to be the same thing then you’re on the wrong track. Read further, and improve your knowledge about these terms.
What Is the Difference: Viruses, Worms, Ransomware, Trojans, Bots, Malware, Spyware and so on ?

 if you’re a regular or even an occasional computer user, then you might’ve heard the terms like Viruses, Worms, Trojans, Bots, Malware, Spyware, etc. But honestly speaking, we consider all these to be a Virus, no matter, whatever be their type. But have you ever tried to acknowledge, what is the difference between these terms, although they are meant to harm your device, steal your data or spy on you, have you ever thought why they are named so differently. Basically, terms like Viruses, Trojans are all types of malicious software or simply ‘Malware’.
Now, the first and foremost question arises, where did these terms came from?

 Clearly, they are not some out of the world aliens, in fact the real truth is that they were not even created with an intention to harm someone.

 The history of malware attacks goes back to 1949, when John von Neumann, first developed the theoretical base for self-duplicating automation programs, but the technical implementation was not feasible at that time. The term ‘Computer Virus’ was first used by Professor Leonard M. Adleman in 1981, while in conversation with Fred Cohen.

 The first computer virus named ‘Brain’ was coded by two brothers Basit Farooq Alvi and Amjad Farooq Alvi, who were from Lahore, Pakistan. Brain was meant to infect storage media based on MS-DOS FAT file systems. It was originally designed to infect the IBM PC, it replaced the boot sector of its floppy disk with the virus. The virus program changed the disk label to ©Brain and the defected boot sectors displayed this message:

 "Welcome to the Dungeon (c) 1986 Basit & Amjads (pvt) Ltd VIRUS_SHOE RECORD V9.0 Dedicated to the dynamic memories of millions of viruses who are no longer with us today – Thanks GOODNESS!! BEWARE OF THE er..VIRUS : this program is catching program follows after these messages….$#@%$@!! "

 However, as you may presume, there was no evil intention behind this. Alvi brothers said in their interview with TIME magazine, they created the virus only to protect their medical software from piracy, aimed at copyright infringement acts.

 Coming back to Malware, these are malicious software designed to harm a computer which may or may not be connected to a network. Malware only get in to action when there is a computer involved in the game otherwise the term Malware is of no use.

Malware are of the following types:

Worms: These programs have the ability to replicate themselves. Their sole objective is to increase their population and transfer themselves to another computers via the internet or through storage media, all the work is done like a top secret mission hiding their movement from the user. They don’t cause any harm to the computer, their replicating nature consumes hard drive space, thus slow down the machine. Some of the notable worms are, SQL Blaster which slowed the internet for a small period of time, Code Red took down almost 359,000 websites.

 Viruses: They also have the ability to replicate themselves, but they do damage files on the computer they attack. Their main weakness lies in the fact, they can get into action only if they have the support of a host program, otherwise they’re just like a defeated warrior. They stick themselves to songs, videos, and executable files and travel all over the internet. W32.Sfc!mod, ABAP.Rivpas.A, Accept.3773 are some of the examples of Virus programs.

The Virus Gang:


  • File Viruses
  • Macro Viruses
  • Master Boot Record Viruses
  • Boot sector Viruses
  • Multi-Partite Viruses
  • Polymorphic Viruses
  • Stealth Viruses

Feel free to Google anyone of them if you like.

Trojans: Basically, Trojans are no Viruses, and are not meant to damage or delete files on your system. Their sole task is to provide to a backdoor gateway for malicious programs or malevolent users to enter your system and steal your valuable data without your knowledge and permission. JS.Debeski.Trojan is an example of Trojan.

 They are named after the ‘Trojan Horse’ tale, in which Greeks entered the city of Troy with the help of a wooden horse which was meant to be a gift, but turned out to be a sweet poison, as depicted in the movie Troy.

The Trojan Gang:


  • Remote Access Trojans
  • Data Sending Trojans
  • Destructive Trojans
  • Proxy Trojans
  • FTP Trojans
  • Security Software Disabler Trojans
  • Denial-Of-Service Attack Trojans

Feel free to Google anyone of them if you like.

Adware: Adware are used to display advertisements in the programs. They generally come attached with software programs that are free to use as they are the only source of revenue for the developers of those software programs. Adware can’t be completely called as Malware as they have no intention to harm your machine, they only track what advertisements you’re more interested in, so as to display the relevant advertisements on your screens.

 Spyware: These programs also come attached with other freeware software, track your browsing and other personal details and send it to a remote user. They can also facilitate installation of unwanted software from the internet. Unlike Adware, they work as a standalone program and do their operations silently.

 Spam: You get very irritated when you receive unwanted emails from unknown senders, these are called Spams or junk mails. And the process of flooding the internet with the same message is called Spamming, is done for the purpose of commercial advertising. These junk mails may sometimes contain Viruses or Trojans that enter your system as soon as you open the mail.

 Bots: Bots or Robots are automated processes that are designed to interact over the internet without the need of human interaction. They can be used for good and bad intentions. An evil minded person can create a malicious Bot that is capable of infecting the host on its own. After transmitting itself to the host device, a Bot creates a connection with central servers which act as the command centers for the infected hosts attached to that network, called Botnet.

 Their skills include stealing passwords, logging keystrokes, analyzing network traffic, relay spam, launch DoS (Denial of Service) attacks and open back doors on infected hosts. These Bots can be seen as the advanced form of Worms, their infection rate and tactic is more effective than those of Worms. These malicious Bots are created after a lot of hard work done by their malignant creators.

 Ransomware: These type of malware alter the normal operation of your machine, thus barring you to use it properly. Thereafter, these programs display warning messages asking for money to get your device back to normal working condition.

In keeping with Krebs, while previously he had little greater than anecdotal evidence that showed cracked software program as being infested with malware, that state of affairs has now modified.
Security researcher warns on malware-infested cracked software
Tech-Spider: Security researcher warns on malware-infested cracked software
"these days, I heard from Alfred Huger, vp of engineering at Immunet, an anti-virus corporation lately bought through Sourcefire. Huger become attaining out to provide remarks on my 3 rules for on line protection post”, he said.

 Huger told Krebs that the policies should have included this caution: Do not download pirated software and cracks from filesharing networks and cracks sites due to the fact they're a main supply of malware infections,

 The Immunet vp of engineering found out that malware infections are closely correlated with instances in which Immunet users opted to dispute its malware detection for particular documents.

 Documents which can be flagged by way of anti-virus applications, he provides, are taken into consideration malicious and are positioned in a quarantine area at the person's device. But if customers nevertheless want to get entry to the report, or they don't agree with or care this is malicious, they can reverse or `roll back' that flag.
"A roll back to us is a file which we [flagged as infected] but humans disagreed with the conviction and rolled it out of quarantine", Huger told Krebs, including that in nearly every case in which customers had rolled returned an infection flag, it involved cracked or pirated cloth of some kind.

 As an instance, Huger stated that in the preceding week, extra than a hundred Immunet customers had rolled lower back infected documents that set up copies of the Conficker worm, amongst other malware.

 "i am doing false high quality management once more this morning", Huger informed the safety researcher ultimate week.

 "inside the closing 7 days 484 people in my network rolled this out from quarantine. It's irritating to see due to the fact I recognise once they get infected it will be natural misery for them", he stated.

 Krebs says that he hopes that it's far clean from his security blog that downloading pirated software program and software cracks is among the quickest and maximum likeliest ways to infect your computer with something that in the end fingers manage over of your laptop to someone else.

Tech-Spider: A Homemade Device That Can Steal Keys and Hack Data From Your PC: PITA

he researchers at Tel Aviv college and the Technion of Iran has made a device that would be without problems made at domestic and it captured the stray radio waves emitted by your pc’s processor.

 This round tool has been dubbed PITA by means of its creators and it really works within the toes distance. This expenses much less than $300 the use of the effortlessly to be had additives and the PITA is small sufficient to match inside a bit of pita bread. In reality, PITA is an abbreviation of portable device for trace Acquisition.


 The statistics fetched from the outdoor might be saved locally on an SD card that is housed on the device, or it could be transmitted to the secret agent with the help of WiFi. So, you can seize the electromagnetic waves and use them to decrypt the EIGamal and RSA information from up to 19 inches away.

 The PITA is built the use of simple additives like a WiFi antenna, SDR receiver, capacitors to song the antenna, a loop antenna and is run using four-AA batteries.

 At some stage in the studies, the researchers targeted their attention on GnuPG (or GPG) – a software program implementation by means of the GNU assignment and is widely used. It secures sensitive stuff like BitCoin wallets, emails and conversations.
 Nicely, the human beings at GNU have already issued an replace towards this unique assault.
However, this technique may also be used in opposition to RSA and other sorts of encryption and the PITA group is operating to increase the range of the device.
