ICT Security-Sécurité PC et Internet

Security researchers have been warning for years that poor security for internet of things devices could have serious consequences. We’re now seeing those warnings come true, with botnets made up of compromised IoT devices capable of launching distributed denial-of-service attacks of unprecedented scale.

Octave Klaba, the founder and CTO of French hosting firm OVH, sounded the alarm on Twitter last week when his company was hit with two concurrent DDoS attacks whose combined bandwidth reached almost 1 terabit per second. One of the two attacks peaked at 799Gbps alone, making it the largest ever reported.

According to Klaba, the attack targeted Minecraft servers hosted on OVH’s network, and the source of the junk traffic was a botnet made up of 145,607 hacked digital video recorders and IP cameras.

With the ability to generate traffic of 1Mbps to 30Mbps from every single Internet Protocol (IP) address, this botnet is able to launch DDoS attacks that exceed 1.5Tbps, Klaba warned.

Web users face an even greater threat to their privacy as large ISPs align themselves more closely with data brokers to track their customers, an advocacy group said.

Several large ISPs have either formed partnerships with, or acquired, data tracking and analytics firms in recent years, giving them a "vast storehouse of consumer data," according to a report Wednesday from the Center for Digital Democracy.

"ISPs have been on a shopping spree to help build their data-targeting system across devices and platforms," the report says. "Superfast computers analyze our information ... to decide in milliseconds whether to target us for marketing and more."

Through digital dossiers that merge all of this information, we can be bought and sold in an instant -- to financial marketers, fast-food companies, and health advertisers -- all without our knowledge."

ISPs are increasingly using programmatic advertising "fueled by powerful alliances among data, media, advertising and technology companies," the report says. The new advertising model "encompasses nearly all the device and formats we rely on -- including mobile, audio and video."

Some ISPs now have the ability to marry a customer's Web surfing history with his or her TV viewing habits and mobile app use to target advertising across devices, the report says.

Hosting company OVH has been subject to the biggest attack DDoS known to date, with peaks of over 1 Tbps of traffic.

Over the past week, the company has been subjected to an attack greater than the one suffered by Krebs on Security.

The attack led to company founder and CTO Octave Klaba tweeting, “last days, we got lot of huge DDoS. Here, the list of ‘bigger that 100Gbps' only. You can see the simultaneous DDoS are close to 1Tbps!”

Klaba also shared a screenshot of the multiple attacks on its infrastructure that when added together produced the 1Tbps directed at the company. The biggest single attack was documented at 799Gbps.
