What this means

A ‘modified’ result doesn’t by itself mean the document is fake – but a bank statement that was changed after it carried a digital signature is exactly the pattern you care about. The signature was meant to freeze the document; something rewrote it afterwards.

For a document that should have been issued by an institution, reject it and ask for an untouched, properly issued original.
