Microsoft on Friday warned that attackers are exploiting a critical unpatched Windows vulnerability using infected USB flash drives.
The bug admission is the first that affects Windows XP Service Pack 2 (SP2) since Microsoft retired the edition from support , researchers said. When Microsoft does fix the flaw, it will not be providing a patch for machines still running XP SP2.
In a security advisory , Microsoft confirmed what other researchers had been saying for almost a month: Hackers have been exploiting a bug in Windows "shortcut" files, the placeholders typically dropped on the desktop or into the Start menu to represent links to actual files or programs.

Microsoft said that all still-supported versions of Windows, including Windows XP SP3, Vista, Server 2003, Windows 7, Server 2008 and Server 2008 R2, contain the bug. The betas of Windows 7 SP1 and Server 2008 R2 SP1, which the company released last week, are also at risk.
Windows XP SP2 users must upgrade to XP SP3 to receive a patch for the shortcut flaw when it eventually ships.
