Re: Just because you have found a file on the internet doesn't mean it's a security issue.
Were all of these tax papers in one or two treasure chests from some sloppy accountant(s) or were they several thousands of returns all stuck somewhere by people dealing with their own affairs? The headlines are wonderful fodder but I do wonder quite what was actually happening, e.g. were the files orphaned off by some now shuttered enterprise? Deluging authorities with complaints might be fun for some, but will it simply slow up any resolution?
There are already tens, perhaps thousands of SMEs who are being scared about GDPR and wondering what, if anything they can do. A 'business' with a few thousand pounds of turn over is clearly not in line to spend huge amounts on a consultant to verify their system, paying their increasing business rates is probably further up their action list. HMRC forcing as many as they can to go digital probably have not helped, at least an old exercise book had no online presence or rapid search function and probably held minimal personal data anyway. Middle ranking outfits possibly have more data, processes, and greater risks of missteps and a number of obsolete.systems.
The glib let them fail and put several hundred out of work is all very well, especially if they were the last available supplier. The care sector is already struggling, the loss of a few more providers would help no one I can think of.
I know of a raft of services that are being shuttered offering a range of facilities, it is a right pain in the behind, but no great harm to me, yet.
I bet I see no reduction in the crap mails and telephone calls I get.
