Android Phones Vulnerability – NFC Exploited

Posted on: July 27th, 2012 by Tetrabyte No Comments

Charlie Miller, an experienced hacker has managed to hack into Android phones using nothing but a short range radio technology called ‘Near Field Communication’ (or NFC for short).

The short range technology can inject an Android phone with a particular set of code and direct it to websites, activate viruses and even steal data stored on the device.

NFC is being introduced in mobile phones in order to enter the credit card market – it has recently been announced that the iPhone 5 will contain an NFC chip, potentially making it possible to make transactions using the flagship phone.

Anti-Virus – Which is The Best?

Posted on: June 13th, 2012 by Tetrabyte No Comments

One of the main things to consider when using a computer is which Anti-Virus to purchase.

Tetrabyte Business IT Best Anti-Virus Product

There are both free versions and paid versions – generally the paid versions have more features, such as Anti-Spam, Identity Theft Protection and Parental Controls, but do you really need these features from your Anti-Virus suite?

E-Mails – most people use providers such as Gmail, Hotmail, Yahoo and similar online providers which already have this built-in.

Parental Controls – Do you have kids? If so this may be a good idea to have, but there are numerous free options to this such as OpenDNS.

Identity Theft Protection – To be honest, this doesn’t mean much. It may flag up phishing websites here and there but your Anti-Spam will block these from your E-Mails, and Internet Browsers such as FireFox, Internet Explorer and Google Chrome do this automatically based on large open-source databases.

The best free Anti-Virus software I would recommend is Microsoft Security Essentials. It doesn’t take up much of your computer resources and isn’t intrusive – it will only pop-up if it detects a virus, and with real-time scanning in the background you’re generally pretty safe.

Iran Finds Cure to Malware Attack

Posted on: May 30th, 2012 by Tetrabyte No Comments

Iran has found a cure to the malware known as ‘Flame’ – a sophisticated piece of malware designed to infiltrate any network it can and steal data.

The malware injects itself into a network, scans to see what ant-virus software there is on the network and then adjusts itself accordingly to be invisible to the anti-virus software.

Iran has developed tools which can detect Flame and remove the malware from infected machines.

The malware was discovered by a number of security firms working together after thousands of machines hard drives have been miraculously wiped across the Middle East.

Russian Cyber-Criminal Sentenced in Armenian Court

Posted on: May 29th, 2012 by Tetrabyte No Comments

The cybercrime mastermind who created the ‘Bredolab’ botnet has been sentenced to four years in jail.

Georgiy Avanesov of Russia has been sentenced in an Armenian court – the first time a cyber-criminal has been convicted in Armenia.

The botnet was sending out an estimated 3.0 billion E-Mails a day on behalf of scammers; this was all done using a network of standard everyday computers from all over the world.

The owner of the botnet has an income of about £80,000 a month for his efforts – at the cost of money from the people who were scammed.

In 2010 the police managed to corner the botnet and take control – releasing those computers which were infected and stopping the high volume of spam from being sent.

Facebook Encourages Anti-Virus Use

Posted on: April 27th, 2012 by Tetrabyte No Comments

Facebook has garnered much criticism over the years over privacy concerns and the lack of security on the website.

Facebook ‘Applications’ are used throughout the web – you can login to various websites using your Facebook credentials where this feature has been enabled.

When you login to a specific website using your Facebook credentials you are given a prompt asking your permission to let the website interact with your Facebook account. You cannot choose which permissions you will give the website; it’s simply a ‘yes’ or ‘no’.

Once a website has access to your Facebook account it can post on your news feed on your behalf – it is this which causes Facebook users so many problems. A website can post any link it likes to your Facebook page for all your friends and subscribers to see.

Facebook has very recently announced a partnership with the following five Anti-Virus firms:

– Microsoft
– McAfee
– Trend Micro
– Sophos
– Symantec

These firms are going to work alongside Facebook to block the links which are dangerous – for example those which have been identified as dangerous, pornographic or generally unsuitable for the Facebook audience.

I for one am looking forward to this – hopefully I won’t need to be worried about the links and pictures that appear in my Facebook newsfeed!

The Media, Hacking, & The Internet

Posted on: April 23rd, 2012 by Tetrabyte No Comments


As you will be aware, there has been a lot in the news over the past few months about websites being hacked and personal details being stolen.

Not only that, but some of these personal details are being published on the Internet for anybody to see.

The motives for these recent hacking attempts aren’t well publicised, but the fact that the hacking attempts (and successes) are broadcast across every media channel you can think of.

So what are the motives?

Well, some may tell you that it’s purely to cause chaos, but let’s take a look at the latest hacking attempt:

The Home Office recently set out plans to monitor the web use of every resident in the United Kingdom – very scary thought. Do you really like the idea of the secret service being able to view everything you do online? Every website you visit? Every E-Mail you send?

I certainly don’t.

In response to this news the hacking collective known as ‘Anonymous’ set out a strategic plan to take the Home Office website offline using a method called a ‘DDOS’ attack – an attack which uses tools to automatically bombard a website with too many requests.

All in all, the headlines may make the bad guys look – well, bad, but do your research. They may turn out not to be so bad after all…

Apple tool to combat Flashback Trojan

Posted on: April 16th, 2012 by Tetrabyte No Comments

Apple has now release a Java update to eradicate the Flashback Trojan that have been infecting Mac computers on a large scale in recent weeks.

The Flashback Malware exploiting a security vulnerability in the Mac Operating System (OS) allowing hackers to take control of the users machine.

Apple released the update two days after it reported taking the issue on and one week after the anti-virus firm Dr Web said over 600,000 Macs had been infected.

Apple has been highly criticised for the extended amount of time it took to resolve the issue.

Kaspersky, recalled its own Trojan-removal tool after it was reportedly affecting some user settings.

Apple have only released a fix for machines running their latest versions of the operating system. “Snow Leopard” and “Lion” all earlier versions have been told to disable Java in their web browser to resolve the problem.

Apple has been reported to be working to shut down servers hosted by the authors of the Malware, to prevent the Malware from running many of its critical functions.

Some analysts are reporting they believe Apple could of been able to avoided the attack if it had acted sooner.


Oracle The Java’s developer had issued a fix for other systems eight weeks before Apple’s first security update.

Rik Ferguson, the director of security at Trend Micro said the following on the matter: “Apple’s sluggishness on security updates could perhaps have been defended in the past by the relative paucity of malware on that operating system. However, Mac OS is increasingly attractive and increasingly exploited by criminals.”

Apple is also trying to improve the security of its web stores iTunes, most likely trying to address a worrying increase in the number users complaining about accounts being “hacked”.

Users are currently being prompted on Apples websites to add back-up email addresses and answer security questions to protect their user accounts and data.

Apple has not yet commented on their actions, which has been reported to of confused a large amount of Apple’s regular users.
