Lizard Squad is the name of a group of hackers that, in the past, have done Distributed Denial of Service (DDoS) attacks against high profile companies, such as their Christmas  2014 attack against the PlayStation Network and Xbox Live gaming networks temporarily shutting them down.  A DDoS attack occurs when the hacker is able to mobilize a network of computers often referred to as a botnet to flood a particular website or network with so many communications at the same time that the website or network is unable to handle the high volume and it gets shut down.

Recently a number of businesses in the United Kingdom have been receiving threatening emails purportedly from Lizard Squad threatening a DDosattack unless they pay a five bitcoin ransom.  Now emails are being sent to ordinary citizens around the world threatening a DDoS attack unless a bitcoin ransom is paid.  Here is a copy of such an email that is presently being circulated.  DO NOT CLICK ON ANY OF THE LINKS.

“ATTENTION! FORWARD THIS MAIL TO WHOEVER IS IMPORTANT IN YOUR COMPANY AND CAN MAKE DECISION!

TIPS

There are many things that companies can do to protect themselves from DDoS attacks, however, regular people really have nothing to fear from DDoS attacks and they are never used against ordinary people so if you get this threatening email or a similar one, you can merely ignore it.  In truth the threat is just meant to scare people who are in no danger of a DDoS attack to paying a bitcoin ransom.
