Customers often look for information about malware that may affect them. For the last couple of years, we have shown that malware doesn’t spread evenly across the globe, despite the global nature of the Internet. Threats that rely on social engineering, are not equally effective in different parts of the world due to language barriers or cultural factors. Also sometimes the malware spreads using exploits in applications which also are unevenly distributed around the world. The Microsoft Security Intelligence Report (SIR) volume 6 which was released last Wednesday, provides lots of information about these aspects. The following chart from the SIR compares the prevalence of different categories of malware and Potentially Unwanted Software in some of the world’s biggest economies. The SIR provides examples for many of these differences. For example, it discusses the password stealers that spread using emails in Portuguese that target online users mostly in Brazil, where Portuguese is spoken.
