Hackers could evade most existing antivirus protection by hiding malicious code within ordinary text, according to security researchers.

One of the most common ways of hijacking other people's computers is to use "code-injection" attacks, in which malicious computer code is delivered to and then run on victims' machines. Current security measures work on the assumption that the code used has a different structure to plain text such as English prose.

Now a team of researchers has highlighted a potential future theatre in the virus-security arms race by working out how to hide malware within English-language sentences.

Josh Mason of Johns Hopkins University in Baltimore, Maryland, and his colleagues developed a way to search a large set of English text – mostly composed of more than 15,000 Wikipedia articles and roughly 27,000 books from the online library Project Gutenberg – for combinations of words that could be used in code.

Their program highlighted the text to be used in the instruction set in bold, while leaving the sections to be skipped in plain text, as in the following example: There is a major center of economic activity, such as Star Trek, including The Ed Sullivan Show. The former Soviet Union."
