Reboot Your Routers and NAS Devices
Unless your law firm represents governments or contractors working with the government, generally the threat of hacking by other nation-states or groups acting on their behalf, are often not seen as security concern. However, sometimes the technology utilized by your firm can be commandeered through malware and used as a tool in a larger attack by these groups against other countries or entities who are the actual target of these groups.
It appears that an example of this has recently been discovered (first by researchers at CISCO) and now the FBI and Department of Homeland Security is advising consumers to reboot their home and small business routers and NAS devices in an effort to combat a malware attack affecting more than 500,000 devices.
Stay diligent out there...
