Do you know why the holes were drilled? I know of a process for waterproofing foundations where they drill holes and inject an epoxy resin that saturates area and that may be what it is. Had some guys do this on a customers basement stairwell.

If this is the case you probably have to grind it and or paint over.

On second look I zoomed in to see what you mean and saw the white streaks by the pipes, if so Art is right, I originally saw the brown streaks which look like epoxy injected
