CISA and the CERT Coordination Center (CERT/CC) are aware of multiple
vulnerabilities affecting Dnsmasq version 2.82 and prior. Dnsmasq is a
widely-used, open-source software that provides Domain Name Service forwarding
and caching and is common in Internet-of-Things (IoT) and other embedded
devices. A remote attacker could exploit some of these vulnerabilities to take
control of an affected system.

CISA encourages users and vendors of IoT and embedded devices that use
Dnsmasq to review CERT/CC VU#434904
and CISA ICSA-21-019-01
21 for more information and to apply the necessary update. Refer to vendors
for appropriate patches, when available.

weaknesses in cloud security practices.

In response, CISA has released Analysis
Report AR21-013A: Strengthening Security Configurations to Defend Against
Attackers Targeting Cloud Services which provides technical details
and indicators of compromise to help detect and respond to potential attacks.

CISA encourages users and administrators to review AR21-013A and
apply the recommendations to strengthen cloud environment configurations.

     Microsoft security researchers continue to investigate and respond to the sophisticated cyberattack known as Solorigate (also referred to as Sunburst by FireEye) involving a supply chain compromise and the subsequent compromise of cloud assets. While the related investigations and impact assessments are ongoing, Microsoft is providing visibility into the attack chains and related threat intelligence to the defender community as early as possible so organizations can identify and take action to stop this attack, understand the potential scope of its impact, and begin the recovery process from this active threat. We have established a resource center that is constantly updated as more information becomes available at https://aka.ms/solorigate.

CISA
Releases CISA Insights and Creates Webpage on Ongoing APT Cyber Activity

12/23/2020 12:55 PM EST

 

Original
release date: December 23, 2020

CISA is tracking a known compromise involving SolarWinds Orion products that
are currently being exploited by a malicious actor. An advanced persistent
threat (APT) actor is responsible for compromising the SolarWinds Orion
software supply chain, as well as widespread abuse of commonly used
authentication mechanisms. If left unchecked, this threat actor has the
resources, patience, and expertise to resist eviction from compromised networks
and continue to hold affected organizations at risk.

In response to this threat, CISA has issued CISA Insights: What
Every Leader Needs to Know About the Ongoing APT Cyber Activity. This CISA
Insights provides information to leaders on the known risk to organizations and
actions that they can take to prioritize measures to identify and address these
threats.

CISA has also created a new Supply
Chain Compromise webpage to consolidate the many resources—including Emergency
Directive (ED) 21-01 and Activity Alert AA20-352A:
Advanced Persistent Threat Compromise of Government Agencies, Critical
Infrastructure, and Private Sector Organizations—that we have released on
this compromise. CISA will update the webpage to include partner resources that
are of value to the cyber community.
