Allied Irish Banks’s web and mobile banking portals are ludicrously insecure. Vast numbers of accounts have easily-guessable registration numbers and are thus ‘protected’ by a level of security that is twice as easy to crack as would be provided by a single password containing only two lowercase letters. A person of malicious intent could easily gain access to hundreds, possibly thousands, of accounts as well as completely overwhelm the branch network by locking an estimated several 100,000s of people out of their online banking. Both AIB and the Irish Financial Services Ombudsman have refused to respond meaningfully to multiple communications each in which these concerns were raised privately.
