Long before ransomware and large-scale hacks became everyday problems, viruses were creeping on our desktops and infecting our screens. Somewhere in the world, there is a cynical coder with an ax to grind or bills to pay who can not wait to ruin your day.

Android virus, How to check phone for virus

These days, smartphones and tablets are just as vulnerable as normal computers, and malware is often used to subvert your private accounts. Your phone is a gateway to a lot of personal data, and malware is often designed to get into your email, online banking and applications.

Laziness now could wreak havoc on your smartphone or tablet, plus all the networks it's connected to. The longer you have the malware, the more you will try to manipulate your applications and data as well as steal from you.

Be proactive.There are simple steps to make sure your smartphone is safe from hackers.

The most dangerous situation is when the device is infected, and you do not even realise it. Malware is not advertised. It works as secretly as possible so that you overlook the damage it is causing.

A commonly held belief is that Apple phones and tablets never get malware. But the devices are not impervious to infections and scammers.

Symptoms of an infected device

• Data Usage: The first sign that your phone has a virus is the rapid exhaustion of your data. That's because the virus is trying to run a lot of background tasks and communicate with the Internet. If you do not have an unlimited data plan, this could also cost you money. You may have to buy additional data to keep up with all that wasted processing. Essentially, you're paying for the malware to ruin your device and wreak havoc on it.

• Crashing apps: There you are, playing Angry Birds on your phone, and suddenly it crashes. That's weird. It never used to happen. After the game is blocked a few more times, you start to suspect poultry, play dirty. Most viruses disrupt their normal operations, and it is common for their favourite applications to fail without explanation. Be sure to update all your applications to avoid viral interference.

• Pop-ups: Many websites have pop-up ads. But if you start seeing pop-ups all the time, especially for products or services that look suspicious, you may want to check for a virus. Whatever you do, do not click the links. Virus-based pop-ups are almost always designed to make your device look even sicker.

• Unexplained uploads: Ads and apps that crash are annoying. Mysterious billing will hit you where it hurts, your bank account. It is particularly common among Android users, who find unusual posts in the "SMS" category. Your gadgets are infected with malware and send messages to premium rate numbers.

• Unwanted applications: True to its name, Trojan download applications may seem legitimate. They are designed in the same style as real applications to avoid detection. If you see an application that looks familiar, but you do not remember downloading it, check if it's authentic. If it seems suspicious, erase it.

• Drain the battery: all these digital manoeuvres require a lot of energy. Not only does your phone use more data, but the battery runs out faster too. Like real viruses, malware can leave the body of your device completely depleted.

The symptoms of Apple and Android devices are quite similar, but the treatments can be very different for each. These include removing questionable applications in the configuration. Read more detailed instructions on getting rid of a virus on Android or iPhone or Ipad.

Take the virus threat seriously, because it definitely means it hurts you, and they will not go out on your own. How else can you maintain your security in the wild world of cybercrime?

Android Banking Trojan Virus Android.ZBot infected 52,000 units till now

Details of banking Trojan android virus Android.ZBot that steals credit card details through Web injections. Dr.Web detects a new mobile banking Trojan targeting Android users, a carefully placed with false payment forms to trick users into providing sensitive financial details.

Security experts have found the Trojan virus (Android.ZBot) in February for the first time, and so far seems only active in Russia, after infecting around 52,000 units in 20 different servers of C&C.

Dr.Web employees entitled to access to three of these botnets, where they had found 140-2300 affected android devices. Only 15 of the 20 botnets were at the time of the release of Dr.Web announcement are still active.

Infections occur through a fake Google Play Store application. Infection, as occurs in most cases, if users are careless enough to install third-party applications from unofficial Android app stores. For Android.ZBot, the offender will be disguised as official Google Play Store.

If this application is installed, it immediately asks for administrator privileges. If the user recognizes to refuse the false root privileges and the Trojan Horse, in a desperate attempt, shows a form of false payment on the user's screen, trying one last time before the uninstalled trick. A desperate Hail Mary, but very inefficient.

On the other hand, if it is allowed to install, the Trojan horse hides itself from the home screen, ensures that every time the machine starts it begins with the collection of personal data of users.

Key Features of Android.ZBot allows you to see the use of smartphone and place the payment masterfully in other applications.

Trojan only targets the Russian banking applications, for now

These methods mimic the native user interface of payment of the application and introduced stripped with the WebView component without browser UI.

The Trojan do not works for all applications running on the mobile phone, but only for a selection list, the constantly updated and calls a C&C server, most of them are banking or financial applications related mobilized exclusively in Russia.

"Although this is a classic phishing attack, the way it is done in this particular case is very unique," says Dr.Web team. "Even virus writers often call these malicious features such as injections Web, but is not the case, due to restrictions for Android, Trojans can not injecting external HTML code as one of the attacked dialog applications."

Dr.Web researchers also said that pressing the Back button, if the trogan payment form pops out then it closes itself, an action to create the illusion that this form is actually a part of the application itself and next time people provide personal credentials or payment details and get robbed.

Gunpowder new Android malware spreading in android phones

Gunpowder Android malware: A new android version of malware targets non-residents of China people and infects their Android phones. Researchers have discovered a new family of malware for Android that successfully evaded all antivirus products on the VirusTotal Web service. Palo Alto Networks named this family of malware 'Gunpowder' based on the principal name of the malicious android software, and threat intelligence team of Palo Alto Networks Unit 42 found 49 unique samples through three different variants.

This finding highlights the fine line between "adware" which is not traditionally prevented by antivirus and malware products, with its ability to cause harm.

Gunpowder samples have been uploaded to VirusTotal since November 2014, with all antivirus engines reported this malware as "benign" or "adware", that is verdicts existing controls would not prevent the installation of the malware in android.

During the investigation of the sample, the team noted that the unit 42, although it contained many features of adware, and actually incorporates a popular adware inside her library, also a number of openly malicious activities were discovered, researchers believe characterizes this family as malware, such as collecting sensitive information of users; spread via SMS messages; push potentially fraudulent advertising; and the ability to run additional payloads.

Gunpowder targets Android users in at least 13 different countries, including India. An interesting observation found by Gunpoder reverse engineering is that this new Android family only spreads among users outside China.

The Gunpowder android malware includes legitimate advertising libraries within samples. These ad libraries are easily detected and may also include aggressive behaviors. The malware successfully used these advertising libraries to hide malicious behavior detected by antivirus. While antivirus software can flag Gunpowder as adware, not flag as being overtly malicious.

Users who have executed Gunpowder are shown a notice that include ad library and the advertising is legitimate. "We believe that the notice was intentionally added in order to use the library as legitimate scapegoat", the researchers said.

Gunpowder embed malicious code samples in popular Nintendo Entertainment System (NES) emulator games, which is based on a framework of open source game

Palo Alto Networks has seen a trend of malware authors repackaging Android open source applications with malicious code. Gonpoder makes use of this technique, which makes it difficult to distinguish malicious code to perform static analysis.

From the observation it was found that this malicious Samples support online payments, including PayPal, Moneybookers, Xsolla and CYPay. Also Gunpowder steals your browser history, bookmarksand and other private information of the victims.

In addition, Gunpowder collect information about all apps, android packages installed on the device of the victim. Also it provides capabilities for executing payloads. Dynamic code for loading and executing the payload after decoding reside in "com.fcp.a" and components "com.fx.a".

So far, Palo Alto Networks has observed 49 unique samples of Gunpowder family; and he found three different groups of variants within this family. In particular, variants of group 1 (12 samples) can spread via SMS and attract users to make some payments. Variants in group 2 (16 samples) can only attract users to make a payment, and variants of group 3 (21 samples) do not contain the spread of SMS or attract users to make payments. Group 3 was found to be the newest malware variants of Gunpowder.

This doesn't stop cyber criminals to continue their game, it is likely that you will not even notice that your computer has a virus, so keep that in mind, should not always assume that you are not infected, simply because the system works well. At the end of the day, is the best way to give your PC free of malware to have regular checkups with a good antivirus program and always make sure the operating system is updated.

What Is Malware Types and How They Work?

Various types of mal ware and how do they work?

Mal ware is a general term used for viruses, worms, spyware and other malicious programs that are represented on the Internet. Cause in simple terms, a software that is designed to direct or indirect damage to the computer system referred to as malware.

What Is Malware

Some malicious programs cause serious problems, such as the destruction of the system files, making or interruptions in the operation of the computer or the collection of sensitive information, while others may have a slight effect, and redirecting to pornographic users annoyed with pop-ups and banners.

In the routine, we would often malicious program that was known as a virus, but this is not correct! In fact, as mentioned above, there are several programs, where the virus is evil. Now many of you may be wondering to know what is the difference between the two. Well, this article contains information about the different types of mal ware that exist, how they work and how they differ:

Computer Virus:

As we all know, this is the kind of malware that has become very popular and is one of the most discussed topics in the field of computer security. A virus is a computer program in order to control unauthorized access to an infected machine to data or system performance degradation will be damaged.

Mode of Spreading:

Computer virus works by attaching a file or existing replicas and spread from one computer to another. In most cases tend to infect executable files that are part of the legitimate programs. Therefore, if the infected file is executed on a new computer, the virus is active and the game caused the damage or programmed into the system.

A virus can not damage his duties and replication, if they can be executed. Therefore, the virus is often choose an executable file as host and stick to it. Viruses are divided into two main types:


Types of computer virus
 
Nonresident viruses: These viruses are held in conjunction with the host, perform the necessary steps to find and infect other files, if possible, and transfers control to the main program (host). The transaction will be completed by the virus from the host.

The resident virus: For resident viruses when the infected program is executed by the user, the virus is activated, its own replication load module into the memory, and then control returns to the main program. In this case, the virus remains in the memory to find active waiting for an opportunity to infect other files, even after the main program (host) has been completed.

Damage:

Viruses are known to cause the destruction of data and software. In some cases, a virus can do more than just playing. However, they are for the use of a large portion of the system resources, such as CPU and memory, which affect performance.

Trojan:

A Trojan or Trojan horse called simply. Kind of malicious program that is disguised as something legitimate and useful The main purpose of a Trojan horse is to win the trust of the users from so that you get the permission for the installation. But the back is designed to offer control unauthorized computer to the hacker.

Mode:

A Trojan horse does not depend on the host. Thus, as opposed to a virus, it is not prone to attach to other files. Trojans are often used as video codec software, cracks, keygens and similar programs disguised downloaded from untrusted sources. Therefore, care must be taken taken to untrusted websites offering free downloads.

An example of the poplar DNSChanger Trojan was designed to deflect the victim DNS machine. It was by some dishonest pornographic sites as required video codec to view the contents distributed online.

Damage:

Trojans are known to cause a variety of damage, such as stealing passwords and login data, theft of electronic money, keystrokes, log edit / delete files of user activity monitor, etc.

Worms:

Worms are spread independently to computer programs with malicious intent from one computer to another. Unlike viruses, worms have the ability to work independently and not to bind to a different program.

Mode:

Worms often use a computer network to spread by exploiting the vulnerabilities that exist in the different teams. In most cases, the worms are spread only to operate without any serious change in the computer system.

Damage:

Unlike viruses, worms do not. Damage to the file system and other important programs However, they are responsible for the consumption of bandwidth and expanding network performance.

Spy ware:

Spy ware is a type of malicious software that can collect information about the activities of the target computer without the knowledge of its users. Spy wares such as keyloggers are often used by the owner or administrator of the computer, installed to monitor user activities. This can be a parent tries to his son, who control a company that tries to your employee or someone to spy on your husband / wife has tried to control.

Mode:

Spyware is designed to fully operate in stealth mode, so that their presence is completely hidden by the user of the computer. Once installed monitor all computer activity, including keystrokes, web activities, instant messaging, etc. These log records are kept secret for later access or download online, so that the installer can access spyware.

Damage:

In addition to monitoring, no spyware no. Damage to the equipment But in some cases, the affected computer experience performance degradation.

Adware:

Adware is software that. Automatically displays users without their permission Common examples include pop-ups, pop-unders, and other annoying banners. The main reason for the design of the Adware is to generate revenue for its author.

Mode:

Adware is usually some free services, such as browser toolbars, Video Down loader, etc. If such programs are installed installed, can take over the adware and redirect the user activity appears annoying ads.

Damage:

Adware is harmless in most cases. However, it is known that some spyware that can be used to monitor the browsing habits of users are provided. This can be a threat to the privacy of users.

You can keep your distance ad-ware and mal ware. I hope this article informative and useful. Place your comment.
