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 employed the following approaches to […]

Overview   Microsoft released November 2020 security updates on Tuesday which fix 112 vulnerabilities ranging from simple spoofing attacks to remote code execution, including 17 critical vulnerabilities, 93 important vulnerabilities, and two low vulnerabilities. All users are advised to install updates without delay. These vulnerabilities affect Azure DevOps, Azure Sphere, Common Log File System Driver, Microsoft […]

Overview On November 11, 2020 (local time), Adobe released security updates which address multiple vulnerabilities in Adobe Connect and Adobe Reader Mobile.

Overview Recently, SaltStack released a security update to address multiple vulnerabilities (CVE-2020-16846, CVE-2020-17490, CVE-2020-25592). These vulnerabilities can cause authentication bypass and command execution. SaltStack recommends users upgrade as soon as possible. Salt is an open-source IP architecture management solution written in Python. It has been widely used in data centers worldwide.

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 these addresses include Hitlist27, which […]

Preface Recently, GitHub’s Security Incident Response Team (SIRT) published an article saying that a set of Github code repositories were serving open-source projects that were infected with malicious code (https://securitylab.github.com/research/octopus-scanner-malware-open-source-supply-chain). According to the article, attackers submitted malicious code to the open-source projects, which were referenced by other open-source projects. After being used by developers, these […]

This section presents the exposure of IPv6 assets on the Internet and methods for recon of these assets. IPv6 Evolution With the IoT and 5G gaining ground, the demand of network applications for IP addresses is undergoing an explosive growth. However, the IPv4 address space has been depleted and IPv4 addresses have been unevenly allocated. […]

Overview 2020 H1 witnessed nine Internet of Things (IoT) security events that deserved close attention: Ripple20 0-day vulnerabilities were discovered and affected hundreds of millions of networked devices in various industries across the globe. A high-risk 0-day vulnerability was detected in dozens of Netgear router products. A group of Industrial Control System (ICS) honeypots attracted […]

Introduction As we indicated in the 2018 Annual IoT Security Report, network addresses on the Internet constantly change. Use of historical data to delineate exposure of assets will result in a deviation from reality, presenting a value higher than the actual number. Therefore, to accurately reflect the reality of a given area, we should specify […]

Overview Recently, Google Project Zero published an article about the Windows cng.sys privilege escalation vulnerability (CVE-2020-17087). The vulnerability allows attackers without authentication to trick users into running crafted malicious programs to escalate privileges. At present, this vulnerability has been exploited in the wild, and Microsoft has not released patches to fix it. Users are advised […]
