On September 27th I warned you about the revelation that there was a bug called Shellshock in the Bash command-line interpreter on many operating systems including Linux, Unix and Apple’s OSX that had just been discovered after more than twenty years. This bug is simple to exploit and tremendously dangerous since when exploited by hackers, permits the hacker to take over the computers using the infected operating systems. The Federal Financial Institution Examinations Council (FFIEC) has warned the banking industry that it should take immediate steps to protect itself from this major threat. Hackers have been busy trying to take advantage of this security flaw by attacking servers using affected operating systems while security experts have been equally as busy trying to create new patches. A series of security patches have been released just in the last couple of days. It is also important to know that, as individual computer users, your firewall should protect you unless a hacker tricks you through phishing into clicking on a link and download malware to exploit the flaw.
For all of us, this is a reminder to never click on a link in an email, text message or social media posting unless you are absolutely sure that it is legitimate. Too often, what appear to be legitimate communications with emails are phishing scams with malware attached.
Here are links provided by the Department of Homeland Security which in turn have links to the latest security patches issued by Apple and others to deal with this problem.
