Hackers have latched onto a vulnerability in Internet Explorer patched by Microsoft last week as a useful way to spread malware.
The vulnerability is CVE-2012-1875 – which was patched in MS12-037 as part of the June edition of Microsoft's Patch Tuesday – and it is being exploited in the wild. Attacks are typically delivered by JavaScript code embedded in websites, some of which are actually legitimate. Windows users who visit these sites using unpatched boxes become infected thanks to the JavaScript code, in what industry insiders commonly describe as a drive-by download attack.
