The REvil cybergang is taking credit for Friday's massive ransomware attack against managed service provider Kaseya Ltd. The criminals behind the attack claim it infected 1 million systems tied to Kaseya services and are demanding $70 million in bitcoin in exchange for a decryption key. The attack is considered the single biggest global ransomware attack on record.

CISA and the Federal Bureau of Investigation have shared guidance for managed service providers and their customers impacted by the REvil supply-chain ransomware attack that hit the systems of Kaseya's cloud-based MSP platform. The two federal agencies advise MSPs affected by the Friday REvil attack to further check their systems for signs of compromise using a detection tool provided by Kaseya over the weekend and enable multi-factor authentication on as many accounts as possible.

The U.S. government has stepped in to offer a mitigation for a critical remote code execution vulnerability in the Windows Print Spooler service that may not have been fully patched by Microsoft's initial effort to fix it. In the meantime, Microsoft Thursday put out a new advisory of its own on PrintNightmare that assigns a new CVE and seems to suggest a new attack vector while attempting to clarify confusion that has arisen over it.

The Cybersecurity and Infrastructure Security Agency has issued a notification regarding the critical PrintNightmare zero-day vulnerability and advises admins to disable the Windows Print Spooler service on servers not used for printing. "CISA encourages administrators to disable the Windows Print spooler service in Domain Controllers and systems that do not print," the US federal agency said.

The U.S. Cybersecurity and Infrastructure Security Agency on Wednesday announced the release of a new module for its Cyber Security Evaluation Tool, namely the Ransomware Readiness Assessment. A Department of Homeland Security product, CSET was designed to help organizations assess their security posture, and is applicable to both IT and industrial control system networks.

The US Cybersecurity and Infrastructure Security Agency has released the Ransomware Readiness Assessment, a new module for its Cyber Security Evaluation Tool. RRA is a security audit self-assessment tool for organizations that want to understand better how well they are equipped to defend against and recover from ransomware attacks targeting their information technology, operational technology, or industrial control system assets.

Following the devastating attack on Colonial Pipeline, the largest refined products pipeline in the United States, the Cybersecurity and Infrastructure Security Agency released a fact sheet focusing on the threat posed by ransomware to operational technology assets and industrial control systems.

The Cybersecurity and Infrastructure Security Agency, a federal agency of the US government, has selected Bugcrowd to launch its first federal civilian enterprise-wide crowdsourced vulnerability disclosure policy platform in support of Binding Operational Directive 20-01. CISA will offer this VDP platform service to Federal Civilian Executive Branch agencies which will set a new precedent for federal civilian enterprise-wide security.

The U.S. Cybersecurity and Infrastructure Security Agency today announced that it has partnered with the crowdsourced cybersecurity community for the launch of its vulnerability disclosure policy platform. Working in collaboration with bug bounty platform Bugcrowd and government technology contractor Endyna, CISA introduced its VDP platform to help Federal Civilian Executive Branch agencies identify and address vulnerabilities in critical systems.

The U.S. Cybersecurity and Infrastructure Security Agency on Wednesday announced the availability of a new guide for cyber threat intelligence analysts on the use of the MITRE ATT&CK framework. The MITRE ATT&CK knowledge base of adversary tactics and techniques is widely used by security teams, but recent studies cited by CISA showed that many cybersecurity professionals don't use it to its full potential.
