If possible, scan backup data with an antivirus program to check that it is free of malware. 11 of the CISA-Multi-State Information Sharing and Analysis Center (MS-ISAC) Joint Ransomware Guide. Follow the Ransomware Response Checklist on p.If, despite your best efforts, a ransomware incident occurs at your organization, CISA, the FBI, and NSA say US-based organizations should: Ticket Granting services can be used to obtain hashed credentials that attackers attempt to crack or use in pass-the-hash methods. Minimize the Active Directory (AD) attack surface to reduce malicious ticket-granting activity.

Implement Credential Guard for Windows 10 and Server 2016. Consider disabling or limiting New Technology Local Area Network Manager (NTLM) and WDigest Authentication. Disable the storage of clear text passwords in LSASS memory. Make sure they are recent, cannot be altered or deleted, and cover the entire organization’s data infrastructure.įurthermore, CISA, the FBI, and NSA urge critical infrastructure organizations to apply the following additional mitigations to reduce the risk of credential compromise: Doing backups right is not as easy as some may think. Implement and enforce backup and restoration policies and procedures. MALWAREBYTES RANSOM WARE SOFTWARE
Privilege escalation and lateral movement often depend on software utilities that run from the command line.
Disable command-line and scripting activities and permissions. BlackMatter operatives have been noticed to use compromised credentials during non-business hours, which allows them to go undetected for longer periods. Implement time-based access for accounts set at the admin-level and higher. Many attackers use system and network discovery techniques for network and system mapping. This will hinder an adversary from learning the organization’s enterprise environment. Implement network segmentation and traversal monitoring. Use a host-based firewall to only allow connections to administrative shares via Server Message Block (SMB) from a limited set of administrator machines. Remove unnecessary access to administrative shares, restrict privileges to only the necessary service or user accounts and perform continuous monitoring for anomalous activity. Limit access to resources over the network. Timely patching is one of the most efficient and cost-effective steps an organization can take to minimize its exposure to cybersecurity threats. Keep all operating systems and software up to date. 
Implement and require Multi-Factor Authentication (MFA) where possible and especially for webmail, virtual private networks, and accounts that access critical systems. MALWAREBYTES RANSOM WARE PASSWORD
Devices with local administrative accounts should implement a password policy that requires strong, unique passwords for each individual administrative account. Passwords shouldn’t be reused across multiple accounts or stored on a system where an adversary may gain access. Most of the mitigation strategies will look very familiar to our regular readers, but it’s always worth repeating them.

How to avoid BlackMatter ransomwareĬISA alert lists technical details in the form of Tactics, Techniques, and Procedures (TTPs) based on the MITRE ATT&CK for Enterprise framework, detection signatures, and mitigations. BlackMatter is also named as the likely culprit behind the cybersecurity incident affecting US farmers’ cooperative NEW Cooperative.Īll in all, the BlackMatter group have performed attacks against several US-based organizations and demanded ransoms ranging from 80 thousand to 15 million US dollars in Bitcoin and Monero.
Oil and gas industry (pipelines, oil refineries)Ī recent high-profile victim of BlackMatter was Japan-headquartered manufacturer Olympus which, among others, produces medical equipment. Critical infrastructure facilities (nuclear power plants, power plants, water treatment facilities). On their own leak site, the BlackMatter gang claim not to attack companies belonging to the following six industries, with the caveat that if or when any companies in these industries do get hit, such victims should simply ask for a free decryption: “The project has incorporated in itself the best features of DarkSide, REvil and LockBit” Promises, promises BlackMatter is a possible rebrand of DarkSide, and has some similarities to REvil. BlackMatter ransomwareīlackMatter is a ransomware-as-a-service (RaaS) that allows the developers to profit from cybercriminal affiliates who deploy it against victims. Now, the Federal Bureau of Investigation (FBI), in conjunction with the Cybersecurity and Infrastructure Security Agency (CISA), and the National Security Agency (NSA) have issued a warning on BlackMatter ransomware, and tips on how to avoid it. Despite promises made by the BlackMatter ransomware gang about which organizations and business types they would avoid, multiple US critical infrastructure entities have been targeted.
