A computer malware has spread across more than 150 countries over the weekend, according to BBC.

Countries report that the attack is slowing down, but there are reports of fresh attacks in both Asia and Europe, BBC reported.

Experts still warn people to be mindful of the malware attack as a new workweek begins, BBC reported.

The WannaCry ransomware began on Friday. It begins by taking over peoples computers, storing their files and demanding a $300 payment to get them back.

Thousands of computers across the world have been affected.

So what do you need to know? Heres a quick rundown.

  • More than 200,000 people in at least 150 countries got hit with the cyber attack, Reuters reported. Large corporations felt the brunt of the attack.

  • Hospitals in the UK were also left exposed, BuzzFeed News reported. Ambulances were given alternate routes and equipment actually shut down.

  • Europol director Rob Wainwright from Reuters: "At the moment, we are in the face of an escalating threat. The numbers are going up; I am worried about how the numbers will continue to grow when people go to work and turn (on) their machines on Monday morning."

  • Financial Times put together a timeline on the attack. It started in Europe and slowly spread out to Russia and the United States.

  • John Bambenek, manager of threat systems at Fidelis, told The Financial Times that this is likely the work of an organized criminal group.

  • Microsoft and Windows users should update their software immediately to avoid the massive hack, BuzzFeed News reported.

  • CNBC has a good question-and-answer piece to help you figure out how at-risk you are for the malware. Most people can avoid the attack with up-to-date anti-virus software.

  • Dont pay the ransom, experts told BBC. A Twitter bot exists that shows these payments are being processed, but experts advise against paying criminals. Theres no guarantee youll receive your files back even if you pay.

  • An accidental hero emerged from the attacks. The Guardian reported that one researcher, a 22-year-old expert from England, said he found a kill switch in the malwares code that allowed him to temporarily halt the attack.

  • The hero, who did not reveal his name, told The Guardian the attacks arent over: This is not over. The attackers will realise how we stopped it, theyll change the code and then theyll start again. Enable windows update, update and then reboot.

  • Microsoft called for world leaders to create a set of rules on cyberspace following the attack, USA Today reported. Microsoft President Brad Smith said countries should build a Geneva Convention-like set of rules to protect people from cyber attacks. They need to take a different approach and adhere in cyberspace to the same rules applied to weapons in the physical world. We need governments to consider the damage to civilians that comes from hoarding these vulnerabilities and the use of these exploits.

Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
