Yup, hardcore scale infestation. Most important first step, as recommended by rbarata, is keep it WELL away from all your other plants, orchids or otherwise.
For the scale infestation I had, I found alcohol and soap remedies to be pretty damn useless as a control, although they do temporarily help with the aesthetics.
For eradication, a systemic pesticide such as Imidacloprid is your best bet. Use the dilution recommended for ornamentals. You'll need to spray the affected plant(s) once a week for a minimum of a month, making sure to thoroughly wet the media, too (rbarata's suggestion of a change of media and pot is also a good idea, although for me it wasn't possible, due to around a hundred plants being affected.) Make sure the plant stays dry for at least 24 hours after treating.
The treatment should be continued for at least 2 weeks after the last sighting of live scale/bugs to ensure all eggs have been eradicated, too.
Good luck!
