The star, called KIC 8462852 and nicknamed “Tabby's Star” after Yale University astronomer Tabetha “Tabby” Boyajian, first made news in 2015 when researchers discovered something odd about its light, whose strange brightenings and dimmings have even caused some to speculate it might host alien megastructures around it...These dimming events are far too substantial to be caused by planets crossing the face of the star, so scientists looked for other explanations. Some have even suggested that it might host signs of intelligent alien life—specifically, a Dyson sphere, a hypothetical megastructure built around a star to capture as much of its energy as possible to power an advanced civilization.
North Korea's main spy agency has a special cell called Unit 180 that is likely to have launched some of its most daring and successful cyber attacks, according to defectors, officials and internet security experts
Cyber security researchers have also said they have found technical evidence that could link North Korea with the global WannaCry "ransomware" cyber attack that infected more than 300,000 computers in 150 countries this month. Pyongyang has called the allegation "ridiculous".
The crux of the allegations against North Korea is its connection to a hacking group called Lazarus that is linked to last year's $81 million cyber heist at the Bangladesh central bank and the 2014 attack on Sony's Hollywood studio. The U.S. government has blamed North Korea for the Sony hack and some U.S. officials have said prosecutors are building a case against Pyongyang in the Bangladesh Bank theft.
The Pentagon makes a point:
The U.S. Department of Defense said in a report submitted to Congress last year that North Korea likely "views cyber as a cost-effective, asymmetric, deniable tool that it can employ with little risk from reprisal attacks, in part because its networks are largely separated from the Internet".
This JSON request instructs the alarm clock on every “alarmSound” event to send a HTTP request to the coffee machine. Whilst this may seem a simple and effective way of implementing the Pub/Sub pattern in HTTP, this poses a significant security risk. By not being able to validate if the receiver of the subscribed message wants the message or not, there is effectively a DDOS vulnerability. An attacker with the ability to set subscriptions on the alarm clock can effectively send HTTP messages to any device or internet property they want. If this is done across enough devices, a DDOS vulnerability is created. Toast popping out of a toaster or a car driving across a road traffic sensor could be the trigger of a future large scale DDOS against a web property.
