Russian State-Sponsored Cyber Actors Access Network Misconfigured with Default MFA Protocols

Original release date: March 15, 2022

CISA and the Federal Bureau of Investigation (FBI) have released a joint Cybersecurity Advisory that details how Russian state-sponsored cyber actors accessed a network with misconfigured default multifactor authentication (MFA) protocols. The actors then exploited a critical Windows Print Spooler vulnerability, “PrintNightmare” (CVE-2021-34527), to run arbitrary code with system privileges. The advisory provides observed tactics, techniques, and procedures, as well as indicators of compromise and mitigations to protect against this threat.

CISA encourages users and administrators to review AA22-074A: Russian State-Sponsored Cyber Actors Gain Network Access by Exploiting Default Multifactor Authentication Protocols and “PrintNightmare” Vulnerability. For general information on Russian state-sponsored malicious cyber activity, see cisa.gov/Russia. For more information on the threat of Russian state-sponsored malicious cyber actors to U.S. critical infrastructure, as well as additional mitigation recommendations, see AA22-011A: Understanding and Mitigating Russian State-Sponsored Cyber Threats to U.S. Critical Infrastructure and cisa.gov/shields-up.

Updated: Kubernetes Hardening Guide

Original release date: March 15, 2022

The National Security Agency (NSA) and CISA have updated their joint Cybersecurity Technical Report (CTR): Kubernetes Hardening Guide, originally released in August 2021, based on valuable feedback and inputs from the cybersecurity community.

Kubernetes is an open-source system that automates deployment, scaling, and management of applications run in containers. A container is a runtime environment that contains a software package and its dependencies. Kubernetes is often hosted in a cloud environment. The CTR provides recommended configuration and hardening guidance for setting up and securing a Kubernetes cluster.

CISA encourages users and administrators to review the updated Kubernetes Hardening Guide—which includes additional detail and explanations—and apply the hardening measures and mitigations to manage associated risks.

[WordPress Security] Increase In Malware Sightings on GoDaddy Managed Hosting

Starting about four days ago we saw a sudden uptick in malware sightings on GoDaddy’s managed hosting platform. This includes the MediaTemple, tsoHost, 123Reg, Domain Factory, Heart Internet, and Host Europe Managed WordPress brands. 

We have identified the infection’s indicators of compromise, reverse engineered them, have a theory on the underlying cause, and we have provided full details on the Wordfence blog on how to find out if you’ve been affected by this and how the malware works. You can find the full details on the official Wordfence blog…


So you want to be a cyborg? Brain Computer Interfaces may be the future, but will they be secure?

I am ok with becoming a technologically enhanced human, a cyborg. Franky, this may be inevitable. These advances come with a new set of risks and many of the same old risks as well,

While cybersecurity is a touchstone for many businesses and individuals, neural security may be the future of privacy when it comes to technology. A new study from NCC Group goes into detail on Brain Computer Interfaces (BCIs), which could pose a significant threat to personal freedom. BCIs present a number of ethical, legal and existential questions about how to make assurances about systems that cannot be controlled, such as the human brain.

[Heads Up] FBI: Ransomware Gang Breached 52 U.S. Critical Infrastructure Orgs

The U.S. Federal Bureau of Investigation (FBI) says the Ragnar Locker ransomware gang has breached the networks of at least 52 organizations from multiple U.S. critical infrastructure sectors.

Bleeping computer reported this was revealed in a joint TLP:WHITE flash alert published last week in coordination with the Cybersecurity and Infrastructure Security Agency.

“As of January 2022, the FBI has identified at least 52 entities across 10 critical infrastructure sectors affected by RagnarLocker ransomware, including entities in the critical manufacturing, energy, financial services, government, and information technology sectors,” the federal law enforcement agency said.

“RagnarLocker ransomware actors work as part of a ransomware family, frequently changing obfuscation techniques to avoid detection and prevention.” The flash alert focuses on providing Indicators of Compromise (IOCs) organizations can use to detect and block Ragnar Locker ransomware attacks.

IOCs associated with Ragnar Locker activity include info on attack infrastructure, cryptocurrency addresses used to collect ransom demands, and email addresses used by the gang’s operators. Although the FBI first became aware of Ragnar Locker in April 2020, Ragnar Locker ransomware payloads were first observed in attacks months before, during late December 2019.

Ragnar Locker operators terminate remote management software (e.g., ConnectWise, Kaseya) used by managed service providers (MSPs) to manage clients’ systems remotely on compromised enterprise endpoints. This allows the threat actors to evade detection and make sure remotely logged-in admins do not interfere with or block the ransomware deployment process.

Request for info linked to Ragnar Locker attacks

The FBI asked admins and security professionals who detect Ragnar Locker activity to share any related information with their local FBI Cyber Squad. Useful info that would help identify the threat actors behind this ransomware gang includes copies of the ransom notes, ransom demands, malicious activity timelines, payload samples and more.

The FBI added that it doesn’t encourage paying Ragnar Locker ransoms since victims have no guarantee that paying will prevent leaks of stolen data or future attacks. Instead, ransom payments will further motivate the ransomware gang to target even more victims and incentivizes other cybercrime operations to join in and launch their own ransomware attacks.

However, the federal agency did recognize the damage inflicted to businesses by ransomware attacks, which may force executives to pay ransoms and protect shareholders, customers or employees. The FBI also shared mitigation measures to block such attacks and strongly urged victims to report such incidents to their local FBI field office.
