Two of the common known attacks on computing systems are the deployment of computer viruses and malware.

Computer viruses are minute program which is “embedded inside an application or within a data file which can copy itself into another program“(Adams et al, 2008 ) for the sole determination of meddling with normal computer operations. The consequences may range from corruption and deletion of data; propagation of virus on to network and deployment through attachments through emails in order to further creating havoc to all associated computing devices.

Malwares are mischievous programs crafted to agitate or forbid normal operations to gather selected information which may lead to loss of privacy through exploitation; gain unauthorized entry into system resources and other abusive behavior”. The taxonomy of malware includes: Trojan Horses; Viruses, Worms and Zombies (Adams et al, 2008).

In the web applications technology, the web browser is the center which revolves around the internet entity. One of the main tool architecture for web design is the recruitment of JavaScript in the DOM “Document Object Model.” JavaScripting language has inherent capabilities which could execute dynamic effect within the web browser and DOM. DOM offers logic structure in which the document is accessed and manipulated. As a consequence, this also poses numerous security issue which plague all users and developers alike (Wadlow et al, 2009).

  • Ransomware: The Evolution Of Ransomware?

    The malicious software can lock the data in a way that is not difficult for an expert to reverse (Ali 89). Nevertheless, there is a more advanced method that involves the use of cryptoviral extortion to encrypt data and demand a ransom to decrypt the data. In such case, it is difficult for experts to recover files without a decryption key (Ali 89). Ransomware attacks are normally executed using a Trojan or a file that is disguised as an email attachment that seems legitimate to the user. In the last five years, ransomware attackers were able to target multiple computers through the use of a botnet (Ali 88). A botnet enables cyber criminals to attack an entire system by compromising the network. The ability to kidnap multiple systems makes ransomware a significant cyber security threat. The cybercriminals demand ransom in the form digital currencies such as bitcoins and ukash because they are difficult to

According to the anti-virus firm McAfee, the hackers were seeking source codes to Google, Adobe, Yahoo, and dozens of other high-profile companies (Zetter, 2010). McAfee firm reported the tactics used in the attack were unprecedented and used combined encryption and stealth programming to find an unknown backdoor into Microsoft internet explorer. Because of this vulnerability this allowed an access breach and allowed the hackers to steal intellectual property from Google and gain access to user’s accounts. McAfee researchers believe in detail hackers of Operation Aurora invisibly infiltrated different systems without any visible signs of malicious intent or actions in a couple of steps. The attack started with sending a link in an email or instant message from a “trusted” source directed to the targeted company or user. Since the link was believed to be trusted by the user. The user would click on the link a website that contains a malicious JavaScript payload. Due to the nature of an executable file, the browser will download the malicious JavaScript. The script will include a zero-day Internet Explorer exploit that will download a binary pretending to be Taiwan servers that will execute the payload. This Trojan will open a backdoor that is encrypted and ...
