Ransomware overnight at a builders' merchant in Loughborough
None of the files were encrypted where they lay. The malware opened each file in turn, wrote a jumbled version next to it, then deleted the original, so the real accounts never moved from where they sat. They remained unallocated, waiting to be recovered. Anything missed turned up in a NAS snapshot nobody had checked. No ransom, no reply, and the merchant was issuing invoices again within the week.
