Resturant Sashimi in Maastricht is the best and most successful sushi restaurant in Maastricht.
In 2012, when I was checking out their website before eating there, I noticed that they'd been hacked. Due to an older, not updated and vulnerable CMS, the website was part of a large amount of mass-hacked sites, which were then used to serve malware. When I went to grab some sushi with my girlfriend (now my wife), I told the owner after dinner. He explained to me that the guy who usually takes care of the IT stuff for him moved to the other side of the country, so he asked me if I could take care of it.
I started to clean up the site and got rid of all the malware. Afterwards, I made sure Symantec updated their reputation system, since it can normally take quite some time before it removes sites from their blacklist, and that's not desireable for business owners. Once that was all sorted out, I explained that once a machine has been hacked, or "rooted", you can never be sure you've gotten rid of it all, and it's best to just wipe the machine and start fresh. The owner took that as a good reason to start fresh and comission a new website. This allowed him to get all the features he wanted but were lacking in the old site, which was a nice bonus.
Here are a few of the notable things I did with the website:
