There are reports of fresh attacks of well known Trojan horse ZeuS on Blackberry devices. Blackberry has a special reputation of being a secure platform but recent news are defamatory. Problem becomes deepening when we come across the infecting mechanism of this malware. The Trojan once installed becomes completely invisible leaving no trail to track. ZeuS also known as Zbot is a Trojan horse that steals banking information by keystroke logging.
As South Asia director of Kaspersky Lab puts the present situation as :
“There has been a new wave of malware attack that has started affecting BlackBerry and it has originated from Poland. The aim is to extract banking passwords.”
Trend Micro,a security research firm reported a Zeus Trojan specifically targeting Blackberry devices. Virus notes the keystroke while user using Mobile banking and thus steals the personal information like passwords etc. Amit Nath, Trend Micro’s security manager in India and SAARC elucidated the virus mechanism. Zeus trojan “does not display any graphical user interface that can prompt users about the infection. Instead, it removes itself from the list of applications. The virus can view, delete and forward text messages, block calls, change the administrator on the device and block phone numbers. It allows the hacker to change the telephone number the device sends all the data to in the event that it gets shut down.”
This time Trojan specifically known as BBOS_ZITMO.B waits for to be installed,once installed it disappears,sends “App Installed OK” message to a botnet administrator then takes control over SMS function of Blackberry device. Now the device is infected and malware is ready to perform operations. These operations are commanded by botnet administrator. The actual phone user remains completely ignorant of these commands. In case the virus is apprehended and kicked out the administrator can hand over command privileges to a new administrator number, with the Set Administrator command.
Malware can carry out following commands:
Hiding SMS and sending it to Administrator without any knowledge tp user.
switch the phone on or off remotely.
How a secure platform like Blackberry was cracked is not easy to say,although Research in Motion has nothing uttered about the present scenario but the strong chances about the potential cause of breaching the security may be installing out-of-the-box applications.
So be warned and precautious while executing transactions and other banking options through the mobile phones and do not forget to update the virus database of your antivirus.
When ever you will search for best antivirus on Google, you will be bombarded with tons of options. Most of ant viruses company will claim that your system is infected with viruses and your current Anti-virus program is ineffective to detect viruses and spywares on your system.
Here I’m sharing a quick tip which will help you to find if your currently installed Anti-virus is effective or useless. For this test I’m using Nod 32 antivirus software.
Now save this notepad file and scan it using your antivirus. If your antivirus detects this as virus or threat, this means your Antivirus software is working and is effective. Here is a screenshot using my Antivirus:
In case if your antivirus failed to detect this is threat or virus. It’s time to change your Antivirus.
Boot time scan is run before starting any pc application by an Antivirus software. Some time our PC gets infected by a threat due to our own mistake such as if we disable real-time Antivirus protection or our Antivirus is unable to detect threat due to outdated virus definitions. In some cases it may be possible that Antivirus is unable to delete or quarantine the threat in running condition. In this condition scheduling a boot time scan can remove the threat.
How it Works
When we schedule a boot time scan the Antivirus asks to restart PC. When PC is rebooting than Antivirus don’t allow any application to run instead of Windows files and starts scanning Windows and other files. Due to inactivity of threats Antivirus can easily delete or quarantine the infection. Boot Scan function is rare in Antivirus softwares and here are two good Antivirus programs having boot scan capability.
Avast 5 Home edition
We can schedule Boot scan with Avast. Avast is one of the best Antivirus program having a comprehensive virus database. Avast Home edition is free and working like a paid Antivirus such as Kasperky or Nortan etc. To enable boot scan with Avast :-
Double click on Avast tray located in bottom right corner of desktop (task-bar)
Click on the option “scan computer” and then “Boot-time scan”
Quick is another Antivirus software with which we can schedule a boot time scan. But the only difference that you must be sure about your boot scan scheduling options because after starting the scan Quick heal don’t allow you to control scan i.e. you can’t stop or skip the scan unlike Avast. Besides QuickHeal is not free and you can use only its one month trial for free.
