Bofra exploit hits our ad serving supplier
Some Reg readers may be infected
Important notice Early on Saturday morning some banner advertising served for The Register by third party ad serving company Falk AG became infected with the Bofra/IFrame exploit. The Register suspended ad serving by this company on discovery of the problem.
Bofra/IFrame is a currently unpatched exploit which affects Internet Explorer 6.0 on all Windows platforms bar Windows XP SP2. If you may have visited The Register between 6am and 12.30pm GMT on Saturday, Nov 20 using any Windows platform bar XP SP2 we strongly advise you to check your machine with up to date anti-virus software, to install SP2 if you are running Windows XP, and to strongly consider running an alternative browser, at least until Microsoft deals with the issue.
We have asked Falk for an explanation and for further details of the incident, and pending this we do not intend to restart ad-serving via the company. Falk will, we understand, be making a statement regarding the matter on Monday.
Although the matter was beyond our direct control, we do not regard it as acceptable for any Register reader to be exposed in this way, and wish to apologise sincerely to anyone who was. Further information about this particular exploit is available here or here. ®
