Hello,

Andy from OSM's Data Working Group here.  We've received reports of some strange editing activity in Sweden such as "nudging a hamlet by 2m" or "deleting one created-by tag".  The accounts involved all seem to have been unused for some time - as an example one might have been adding things in Russia 5 years ago, then stopped, and suddenly starts making small edits in Sweden within the last week or so.  The edits themselves don't appear to be particularly problematic - they almost seem to be "just seeing if they can make an edit".

We've had confirmation from some of the accounts that these recent edits weren't made by them, so what we suspect has happened is that people have used the same password for multiple sites on the internet, and if one gets compromised, people can use credentials obtained from there elsewhere.

You can see the changeset discussion comments that I have left at http://resultmaps.neis-one.org/osm-discussion-comments?uid=61942&commented - there are lots of them left at 2020-02-10. Also, some block messages, the "ends in about 1 month" ones at https://www.openstreetmap.org/user/SomeoneElse/blocks_by?page=9 and on the following pages.

If anyone spots anything odd or has got any other questions you can mail OSM's Data Working Group at [email protected] .

Best Regards,

Andy Townsend, on behalf of OSM's Data Working Group.
