Symantec noticed that new Mespam takes advantage of new Web technologies and spreads by injecting malicious links when users interact with the Web.
When users are going to post something on any Web site running VBulletin or phpBB, the Trojan will sneakily add a malicious link into the outgoing Web packet. The same also happens when users are sending emails using clients such as Gmail, Yahoo, Lycos, Tiscali, AOL, and many popular Web-based mail applications.

Bank opts out of anti-virus protection for whitelisting approach
Like a lot of bank IT administrators, Brent Rickels had his fill of the spam and spyware deluge that has increased tenfold since 2002. So he did something about it for First National Bank of Bosque County (TX) last year: He chucked all of the bank’s anti-virus software.
PC hardware components can provide a way for hackers to sneak malicious code onto a computer, a security researcher warned Wednesday.
Every component in a PC, such as graphics cards, DVD drives and batteries, has some memory space for the software that runs it, called firmware. Miscreants could use this space to hide malicious code that would load the next time the PC boots, John Heasman, research director at NGS Software, said in a presentation at this week’s Black Hat DC event
Security giant Symantec has released the first three of six technical research papers evaluating Windows Vista security components.
The research papers cover a range of Vista security mechanisms in-depth, from its Address Space Layout Randomization (ASLR) technology designed to thwart heap overflows and certain malware attack methods, to buffer overflow protection in Vista’s Visual Studio C++ compiler and an evaluation of how well legacy malware works on Vista’s OS.
The dustup revives the issue of how much license security researchers should be given when presenting their findings in the name of better security.
US anti-spyware company Webroot estimates almost one out of every three PCs in SA have some form of spyware on their systems – a claim Standard Bank agrees with.
Daniel Mothersdale, Webroot’s marketing director for Europe, Middle East and Africa, says according to his company’s research, 27% of PCs in SA have some kind of malicious spyware on them. This is just below the estimated 35% of PCs in the UK.
