Microsoft may have a tough time fixing the Windows shortcut vulnerability, a security researcher said. A noted vulnerability expert, however, disagreed, and said Microsoft could deliver a patch within two weeks.
"The way Windows' shortcuts are designed is flawed, and I think they will have a very hard time patching this," said Roel Schouwenberg, an antivirus researcher with Moscow-based Kaspersky Lab.
Microsoft has acknowledged that attackers can use a malicious shortcut file, identified by the ".lnk" extension, to automatically execute their malware by getting users to view the contents of a folder containing a malformed shortcut. The risk is even greater if hackers use infected USB flash drives to spread their attack code, since the latter automatically executes on most Windows PCs as soon as drive is plugged into the machine.
Another problem facing Microsoft is that the code is obviously old, making a quick patch that much more unlikely. The vulnerability exists in Windows as far back as the Windows 2000 edition, which Schouwenberg has tested and successfully exploited.
