It seems pretty weird as my tiny business is hardly running for the US presidency but when I check visitors to my site who have clicked on products but not completed a purchase, 60%+ are from Russia.
Just recently I have found two dbase records that are significantly different from the original entry as logged in my and Paypal's emails and a copy of the table. It can't be a fault in my code due to the nature of the change, the fact that umpteen other records are fine and I haven't changed the code that has been working ok for months anyway.
I have already implemented various protections in my code, HTML entities, length limits, removed MySQL error messages, ensured that INSERT fields can't contain quotes etc. etc. but clearly need to do some more on Monday. Any pointers to best resources? Ta.
