Dan Geer is an extremely well respected security expert. When he worries about something, people listen.The ConsortiumInfo.org Standards Blog: "Monocultures and Document formats: Dan's Bomb Goes Off"
One of the things he has worried - and warned - about is the danger represented by IT 'monocultures' - the situation that arises when everyone uses the same software, for example, and therefore everyone shares the same vulnerability to a computer virus or other security threat.
As it happens, Dan's bomb went off a few days ago, with the breakout of the "Backdoor.Ginwui" virus, a malicious bit of code that Symantec introduced in an alert as follows:It has been reported that Backdoor.Ginwui may be dropped by a malicious Word document exploiting an undocumented vulnerability in Microsoft Word. This malicious Word document is currently detected as Trojan.Mdropper.H.
