All my web sites, perso and pro, were hacked a few days ago. Invisible ads for stuff like cialis and viagra were inserted in all my PHP files and an extra invisible iframe was added to all my HTML files. Nothing else, apparently. I am just one of the 3,500 Dreamhost accounts compromised in the last days. Yes, three thousand five hundreds. I cleaned up everything, changed all paswords, cleaned up my laptop and my desktop, and things are now ok.
