Another shift was an increase in targeted vulnerability attacks where hackers actively seek out security holes in applications, web browsers such as Internet Explorer 8 and Google Chrome and in company servers.
Microsoft not the only target for hackers
Historically, Microsoft has been the prime target for hackers but during 2009 their attention appears to have broadened. This has led to other big software companies reporting critical vulnerabilities in their programs.
Adobe, for example, announced vulnerabilities in its PDF and Acrobat programs. Wordpress blogs have also been susceptible to multiple vulnerabilities leading to passwords being compromised.
Browsers such as Apple Safari, Mozilla Firefox and Opera have also announced critical vulnerabilities.
Worryingly, there’s also been an increase in the number of Trojans stealing personal data such as passwords, information from social networking sites and financial log in details.
