IoT Exploits Viewpoint 3: Over 30 types of IoT exploits were captured, most of which targeted remote command execution vulnerabilities. Though hundreds of to thousands of IoT vulnerabilities were unveiled each year, only a few can exert an extensive impact. Attackers were keen on targeting devices (routers and video surveillance...

Annual IoT Security Report 2019-9
Introduction This chapter analyzes IoT threats from the perspective of vulnerabilities. We first analyze the change trends of IoT vulnerabilities and exploits 1 in the NVD and Exploit Database (Exploit-DB) in 2019 and then IoT exploits captured by NSFOCUS's threat hunting system. The following dwells upon some representative exploits. (more…)
Trend Analysis on 2020 Q3 Phishing Email
Chapter 1. Brief on the risk In phishing email attacks worldwide, Covid-19 is still an important topic. With the increasing availability of epidemic prevention material supplies in various countries and the transparency of news channels, attackers have begun to look for "hot issues" from other perspectives that may attract people's...

Heuristic Recon via the Dual-Stack UPnP Service In addition to the recon of IPv6 addresses based on their characteristics, we can also use UPnP to detect IoT assets by referring to the method described in a blog post 28 from Cisco Talos Labs. Principle UPnP is a set of protocols...

Heuristic Recon of IPv6 Addresses Based on Their Characteristics Previously, we mentioned that IPv6 addresses, when assigned, can, for example, include random values in particular bytes or embed MAC addresses. With these facts in mind, we exercised some restrictions to narrow down the address space to be scanned. Specifically, we...

Identification of IoT Assets from Known IPv6 Addresses The preceding section gives a brief account of difficulties in the blind-scan of IPv6 addresses. To work around these problems, we based our recon on some available IPv6 addresses, in a bid to discover IoT assets operating in IPv6 environments. Sources of...
