An Indonesian hacker known as Hmei7, the one responsible for breaching websites belonging to Microsoft and IBM not long ago, managed to take down a number of six Siemens sites, The Hacker News reports.
Siemens’ websites from Ecuador, Peru, Venezuela, Colombia and Brazil were hacked and altered to display messages and an image of a homeless man using a laptop.
At the time of writing, all the websites, two of which from Brazil, are back online.
It seems Siemens is having a hard time these days after security researcher Billy Rios ashamed them by publicly disclosing some serious authentication bypass vulnerabilities that exist in their SIMATIC systems utilized to control critical infrastructure components worldwide.
They promised to fix the flaws in January 2012, but according to Rios, they were informed of them since May 2011.
