“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.
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.” Stop malicious encryption. Create offsite, offline backups.
Once gained the foothold in the target network, the attackers will attempt lateral movements to elevate the privileges and search for high-value machines to encrypt (i.e. backup servers, network shares, servers, auditing devices). PowerShell) to easily deploy tooling or ransomware.
PYSA, also known as Mespinoza, is capable of exfiltrating and encrypting critical files and data, with the criminals specifically targeting higher education, K-12 schools and seminaries, the bureau warns. The notice also includes mitigation steps like: Regularly back up data, air gap and password-protect backup copies offline.
A few days ago the group released a press release in which they warned the companies to not try to recover their files from their backup, it also announced the forthcoming LG Electronics data leak. Maze ransomware operators have also breached the systems of the Xerox Corporation and stolen files before encrypting them.

Regularly back up data, password protect backup copies offline. hard drive, storage device, the cloud).
But you should also realize that while it’s easy to say that you need reliable and easy to deploy backups for example, it’s not always easy to follow that advice. Maintain offline backups of data, and regularly maintain backup and restoration. Ensure all backup data is encrypted, immutable (i.e.,
update, Apple introduced “Advanced Data Protection,” which finally introduced end-to-end encryption (E2EE) for most items backed up or stored in iCloud. Device backups. Enabling end-to-end encryption (Advanced Data Protection for iCloud). encrypted email providers. With the iOS 16.2 Safari Bookmarks. TABLE OF CONTENTS.
North Korean state-sponsored cyber-actors used Maui ransomware in these incidents to encrypt servers responsible for healthcare services—including electronic health records services, diagnostics services, imaging services, and intranet services. Keep operating systems, applications, and firmware up to date.
Since January, DeadBolt ransomware operators are targeting QNAP NAS devices worldwide, its operators claim the availability of a zero-day exploit that allows them to encrypt the content of the infected systems. Once encrypted the content of the device, the ransomware appends. Make an immediate backup. deadbolt’ extension.”
“Cyber criminal threat actors exploit network vulnerabilities to exfiltrate data and encrypt systems in a sector that is increasingly reliant on smart technologies, industrial control systems, and internet-based automation systems. The good news is in the latter attack the victims restored its backups.
Then the hunt for valuable data and the preparation for the encryption process begins. This means they steal data as well as encrypting systems and then threaten to publish the stolen data on their Dark Web leak site. Stop malicious encryption. Create offsite, offline backups.
“Once the attacker successfully logs in to a device, they encrypt data in shared folders and leave a ransom note with the file name “!CHECKMATE_DECRYPTION_README” ” The ransomware appends the.checkmate extension to the filenames of encrypted files, it drops a ransom note named !CHECKMATE_DECRYPTION_README
