Researchers break into Windows encryption feature  With effort,
hackers are able to break into an encryption feature available
on newer versions of Windows.  Researchers can break into
BitLocker, the disk encryption feature available in Windows 7,
Vista and Server 2008.  German experts from the Franhofer
Institute for Secure Information Technology (SIT) revealed five
attack strategies against BitLocker and the way its Trusted
Platform Module (TPM) sealing mechanism works.  In certain
circumstances, the researchers claim that dedicated hackers
could “circumvent the protection and break confidentiality with
limited effort".  "Our attacks neither exploit vulnerabilities
in the encryption itself nor do they directly attack the TPM,"
the researchers claim in a report.  “They rather exploit
sequences of actions that Trusted Computing fails to prevent,
demonstrating limitations of the technology.”  One attack took
advantage of the boot process, where BitLocker needs to interact
with the user to obtain a password or
