Are backlinks from pandalised websites devalued?
I fail to see how they could be valued as they were prior. If your competitors were utilizing the thin scraper type of sites that got hammered back in Feb to boost their link profiles (press releases, etc.), and those competitors got hammered in a similar fashion in Feb ... that looks like a pretty clear cut case to me.
(This is assuming that you've controlled for/taken into account all other factors -- ex: their sites are otherwise equivalent to your own except for link profiles.)
