Proof-of-concept virus targets AMD systems
A new proof-of-concept virus uncovered by Symantec targets
systems running AMD processors. The virus exists in two separate
variants, dubbed w32.bounds
for 32-bit and 64-bit AMD chips, respectively. It works by binding
itself to executable files and running chip-level assembly code. The
virus writer reportedly chose to target AMD hardware because AMD's
processor families share more similarities with one another than Intel's.
Right now, the virus is only a proof of concept and therefore ranked as
a low security risk. However, Symantec warns that the virus could be
used as a starting point for more malicious and potentially destructive
malware. Symantec Senior Director Vincent Weafer says running code at
the chip level allows viruses to bypass the operating system's kernel
and user protections and do "pretty well anything" the virus writer
might want to do. Thanks to The
