While the statement does not reveal a lot of tangible information, this snippet is important: “MSI urges users to obtain firmware/BIOS updates only from its official website, and not to use files from sources other than the official website.” They are likely from sources that are trying to trick you into installing malware.
The second is that some of the patches require updating the computer's firmware. In November, Intel released a firmware update to fix a vulnerability in its Management Engine (ME): another flaw in its microprocessors. The vulnerability that allowed them to be taken over by the Mirai botnet last August simply can't be fixed.
Early this month, Evgueni Erchov, Director of IR & Cyber Threat Intelligence at Arete Incident Response, told ZDNet that multiple ransomware gangs are cold-calling victims if they don’t pay the ransom and attempt to restore from backups. Patch operating systems, software, firmware, and endpoints.
“They are also urged to read the NCSC’s newly-updated guidance on mitigating malware and ransomware attacks , and to develop an incident response plan which they regularly test.” backup servers, network shares, servers, auditing devices). ” reads the advisory.
The best defense and the best option for recovery will always be the availability of sufficient, isolated data backups and a practiced restoration process. However, even with the best planning, organizations can find a few users, machines, or systems that were overlooked or whose backup may be corrupted or encrypted.
“With a cyberattack, it’s more than just data that needs protecting—at risk is really the entire physical infrastructure from applications and operating systems down to low-level firmware and BIOS. This type of backup and DR technology offers RPOs measured in hours. See the Best Backup Solutions for Ransomware Protection.
The BlackCat/ALPHV a Ransomware was first discovered in December by malware researchers from Recorded Future and MalwareHunterTeam. The malware is the first professional ransomware strain that was written in the Rust programming language. Regularly back up data, air gap, and password-protect backup copies offline.
“As a result, AvosLocker indicators of compromise (IOCs) vary between indicators specific to AvosLocker malware and indicators specific to the individual affiliate responsible for the intrusion.” Implement network segmentation and maintain offline backups of data to ensure limited interruption to the organization.
While anyone can fall victim to these threat actors, the FBI noted that this malware has been used to target a wide range of businesses and critical infrastructure organizations, including defense contractors, educational institutions, manufacturers, technology companies, and especially organizations in the healthcare and medical industries.
Mamba ransomware is one of the first malware that encrypted hard drives rather than files that was detected in public attacks. The alert provides a list of mitigations to stay protected from ransomware families: Recommended Mitigations • Regularly back up data, air gap, and password protect backup copies offline.
According to the advisory that was issued with the help of leading cybersecurity firms (Dragos, Mandiant, Microsoft, Palo Alto Networks, and Schneider Electric), nation-state hacking groups were able to hack multiple industrial systems using a new ICS-focused malware toolkit dubbed PIPEDREAM that was discovered in early 2022.
The good news is in the latter attack the victims restored its backups. The FBI provided the following mitigations to protect against ransomware attacks: Regularly back up data, air gap, and password protect backup copies offline. Install updates/patch operating systems, software, and firmware as soon as they are released.
Below are the recommended mitigations included in the alert: Implement regular backups of all data to be stored as air gapped, password protected copies offline. Install updates/patch operating systems, software, and firmware as soon as updates/patches are released.
Find and delete shadow volume copies, and other recent backups, and disable the Windows recovery environment. Store regular backups of your data off-site and offline, where attackers can’t reach them. Install and regularly update anti-malware software on all hosts and enable real-time detection. Those extensions are .RNZ

The FBI has observed instances where Zeppelin actors executed their malware multiple times within a victim’s network, resulting in the creation of different IDs or file extensions, for each instance of an attack; this results in the victim needing several unique decryption keys.” ” reads the joint advisory.
Malware detection has long been a game of signature detection. With ML and artificial intelligence (AI) using thousands of strains to train algorithms, one would surmise that the ability to detect malware is only improving. Hackers are using the same ML and AI technology to avoid using recognized malware. Old way New way.
