In my own native Netherlands, the recent combination of spring tide and northwesterly storm raised water in coastal province, Zeeland, to the highest levels since the devastating 1953 North Sea flood, when water levels rose to 4.55 meters above sea level. In the German city of Magdeburg, 23,000 people were forced to leave their homes last year after a dam burst on the flood-swollen River Elbe. Further downstream, the Thames Flood Barrier has closed a record 28 times since December 2013, representing one-fifth of all closures since it was inaugurated in the 1980s. In the UK, the River Thames reached record high levels in February 2014. The European Environment Agency lists more than 175 major floods over the last 10 years, and predicts that flooding and other severe weather conditions will only continue to increase due to climate change. In recent months, many parts of Europe have been exposed to extreme weather episodes that have significantly disrupted day-to-day life, stretched emergency response services and most sadly, resulted in tragic loss of human life. Below, Djeevan Schiferli argues that the ability to make better use of all this data can dramatically improve the way cities, businesses and citizens plan for and manage the harsh conditions that extreme weather throws at our urban centres. Or they may have simply used old-fashioned investigative techniques such as turning administrators into informants, or found other hackable vulnerabilities in the target sites.Some European cities are turning to Big Data to not only predict the weather and its potential impact, but also to address public safety and business concerns that accompany adverse conditions. For now, just how the feds located those sites remains a mystery Some security researchers speculate that government hackers used so-called "denial of service" attacks that flood Tor relays with junk data to force target sites to use Tor relays they controlled, thus tracing their IP addresses. In early November, a coordinated action by the FBI and Europol known as Operation Onymous seized dozens of Tor hidden services, including three of the six most popular drug markets on the Dark Web. Just how completely Tor can evade the surveillance of highly-resourced law enforcement and intelligence agencies, however, remains an open question. Even Facebook has launched a Dark Web site aimed at better catering to users who visit the site using Tor to evade surveillance and censorship.

That idea has since been adapted into a tool called SecureDrop, software that integrates with Tor hidden services to let any news organization receive anonymous submissions. Though the Dark Web is most commonly associated with the sale of drugs, weapons, counterfeit documents and child pornography-and all those vibrant industries do in fact take advantage of Tor hidden services-not everything on the Dark Web is quite so “dark.” One of the first high profile Dark Web sites was the Tor hidden service WikiLeaks created to accept leaks from anonymous sources. That means anyone can visit a Dark Web site, but it can be very difficult to figure out where they’re hosted-or by whom. In fact, the Dark Web is a collection of websites that are publicly visible, yet hide the IP addresses of the servers that run them. The Dark Web isn’t particularly vast, it’s not 90 percent of the Internet, and it’s not even particularly secret.

But when a news organization as reputable as 60 Minutes describes the Dark Web as “a vast, secret, cyber underworld” that accounts for “90 percent of the Internet,” it’s time for a refresher. With the rise and fall of the Silk Road-and then its rise again and fall again-the last couple of years have cast new light on the Dark Web. While it's most famously been used for black market drug sales and even child pornography, the Dark Web also enables anonymous whistleblowing and protects users from surveillance and censorship. The Dark Web is a collection of thousands of websites that use anonymity tools like Tor and I2P to hide their IP address.
