If you can flip the PT_DENY_ATTACH bit then surely you can alter other variables as well.<BR/><BR/>But yes, I take your point, you're already root so you're already there.<BR/><BR/>petePeter Markshttps://www.blogger.com/profile/13007012724570360389noreply@blogger.comtag:blogger.com,1999:blog-35901825.post-42395947108910183522008-01-31T15:31:00.000+10:002008-01-31T15:31:00.000+10:00Another great chat, thanks guys.A bit confused abo...Another great chat, thanks guys.<BR/><BR/>A bit confused about Pete's comments around PT_DENY_ATTACH; exactly what is the security risk here? You seemed to be saying that malware could use it to access other processes, but wouldn't they need root access? And if they had root access, well, a security violation has already happened surely?<BR/><BR/>As for eSATA on Mac, I'm happy to report that it'sAlastairhttps://www.blogger.com/profile/13954201522416957112noreply@blogger.comtag:blogger.com,1999:blog-35901825.post-70973971636020330832008-01-29T16:29:00.000+10:002008-01-29T16:29:00.000+10:00Thanks Alan.I think the history of domain name reg...Thanks Alan.<BR/><BR/>I think the history of domain name registration economics will be a fascinating study in the operation of the free market.

It must be an enormous pain to registrars.
