Despite the recent economic downturn, phishing and spam scams are still profitable for attackers, possibly because phishers are able to quickly target their scams to match prevailing attitudes. For instance, phishers are enticing potential victims with lures that spoof well-known financial institutions and which promise easy access to low-interest loans and credit. Spammers are also attempting to use the uncertainty of the financial situation to their advantage. While it might be expected that spam offering stock market tips or other financial opportunities would drop off during a period of market uncertainty, it is likely that such a drop-off would be balanced out by an increase in spam offering such recession-related enticements as low-interest loans and easy access to credit.
Many phishing attacks that spoof financial services brands prompt users to enter credit card information or banking credentials into fraudulent sites. If this ruse is successful, phishers can then...
A driving force behind the growing speed and efficiency of malicious code development is the demand for goods and services that facilitate online fraud. This is demonstrated by the flourishing profitability of confidential information sales in the online underground economy. For example, one person who was arrested for computer related credit card fraud in 2008 had possession of a condominium, a luxury vehicle, and over 1.6 million dollars in cash, among other valuable goods. All of which were presumably obtained by fraudulent means.
Malicious code that exposes confidential information is of particular value because the information is critical to several illegal practices, such as identity theft and credit card fraud. In many instances, well-organized programmers are developing this code on a large scale, much as how development occurs in a legitimate software enterprise. The confidential information obtained by the malicious code is then used for fraud or advertised for...
The prevalence of Web-based applications and the ease of which these applications can be exploited using vulnerabilities have contributed to the widespread nature of Web-based attacks. Attackers can successfully reach and compromise a massive number of targets, and this remains as the source of motivation behind Web-based attacks. Attackers who wish to take advantage of client-side vulnerabilities no longer need to actively compromise or break into specific networks to gain access to those computers. Instead, by attacking websites, attackers can use them as means to mount client-side attacks.
An attacker can exploit any number of Web application vulnerabilities, such as SQL injection vulnerabilities, to help mount their Web-based attack. Surprisingly, many of these vulnerabilities are not used to directly compromise enterprise data assets or gain access to sensitive information. They are used simply as a way of injecting malicious content into websites as a means of...
