Securing the Internet of Things (IoT): Challenging but Critical

by vmstoday - on Nov 23rd 2016 - No Comments

This week, we are discussing IoT security. If IoT devices and ip cameras are not secured, hackers can use them to gain access to the enterprise network, to distribute malware, or to launch distributed denial of service (DDoS) attacks. As in the case of recent incidents for Dahua, Hikvision and others security camera manufacturers. According to a recent report from Flashpoint and Level 3 Threat Research Labs, botnets made up of hundreds of thousands of compromised IoT devices are already being used to launch massive DDoS attacks.

IoT devices and the most massive DDoS attack on record (620 Gbps)

Originally, this story was focused on the DDoS attack on the KrebsOnSecurity site. While the bulk of this story is still focused on that specific attack, it has already been overshadowed by the massive attack that took down major service sites like Netflix and Twitter through an attack on DNS provider Dyn. The most recent attack may have drawn more attention to the threat but an analysis of the Krebs attack provides a clearer view of the details if only because effort was taken to identify the specific nodes that were launching the assault. One thing that both attacks have in common is that they were the result of exploitation of unaddressed, easy-to-fix weaknesses in both process and product.  (more…)

Hackers hijack CCTV cameras and network-attached storage devices to launch DDoS attacks

We’ve reached a point that security researchers have long warned is coming: insecure embedded devices connected to the Internet are routinely being hacked and used in attacks.

The latest example is a distributed denial-of-service (DDoS) attack detected recently by security firm Imperva. It was a traditional HTTP flood aimed at overloading a resource on a cloud service, but the malicious requests came from surveillance cameras protecting businesses around the world instead of a typical computer botnet.

The attack peaked at 20,000 requests per second and originated from around 900 (more…)
