An object lesson in website vulnerability was learned the hard way by drink distributor Dave Robinson.
Having secured the rights to US aphrodisiac drink Turn On, Robinson was busying himself signing up Australian distributors. He was using his website as a central resource and selling tool until hackers turned him off, then demanded a $5000 ransom.
It took a week to get the site back up and cost tens of thousands of dollars in lost revenue. He is still trying to get in touch with his lost customers.
There is no predicting if or when an attack might come. Most are just random tamperings with vulnerable sites. So this is a salutary reminder to all website owners to maintain a relationship with your web developer, discuss with them the tools that might reduce the impact of an attack and backup, backup and backup.
