![]() ![]() Organizations such as CISA, NCSC, the FBI, and HHS caution ransomware victims against paying a ransom partly because payment does not guarantee that files will be recovered. Best Practices include Not Paying a Ransom These services are powered by our global FortiGuard team of seasoned cybersecurity experts. Cloud-based security solutions, such as SASE, to protect off-network devices advanced endpoint security, such as EDR (endpoint detection and response) solutions that can disrupt malware mid-attack and Zero Trust Access and network segmentation strategies that restrict access to applications and resources based on policy and context, should all be investigated to minimize risk and to reduce the impact of a successful ransomware attack.Īs part of the industry's leading fully integrated Security Fabric, delivering native synergy and automation across your security ecosystem, Fortinet also provides an extensive portfolio of technology and human-based as-a-service offerings. When coupled with digital supply chain compromise and a workforce telecommuting into the network, there is a real risk that attacks can come from anywhere. Organizations will need to make foundational changes to the frequency, location, and security of their data backups to effectively deal with the evolving and rapidly expanding risk of ransomware. Our FREE NSE training: NSE 1 – Information Security Awareness includes a module on internet threats designed to help end users learn how to identify and protect themselves from various types of phishing attacks and can be easily added to internal training programs. The FortiPhish Phishing Simulation Service uses real-world simulations to help organizations test user awareness and vigilance to phishing threats and to train and reinforce proper practices when users encounter targeted phishing attacks. Since the majority of ransomware is delivered via phishing, organizations should consider leveraging Fortinet solutions designed to train users to understand and detect phishing threats: The ransom note threatens victims that unless they send 10,000 USD worth of Monero (XMR) cryptocurrency to the attacker’s wallet within 72 hours, their encrypted files will be lost forever.įortinet customers are already protected from this malware variant through FortiGuard’s Web Filtering, AntiVirus, and FortiEDR services, as follows:įortiGuard Labs detects known Dark Power ransomware variants with the following AV signatures:įortiGuard Labs detects known PayMe100USD ransomware variants with the following AV signature:ģ3c5b4c9a6c24729bb10165e34ae1cd2315cfce5763e65167bd58a57fde9a389ġ1ddebd9b22a3a21be11908feda0ea1e1aa97bc67b2dfefe766fcea467367394Ĭ2aa5d89d1fb63c65806a789f529daf774ceff411338c43438ea6c0175e10fd0Ĥdaca38854ba0a471d25250f106122ff81b8bbda2b19569a9e0b6e7f56187746ĭue to the ease of disruption, damage to daily operations, potential impact to an organization’s reputation, and the unwanted destruction or release of personally identifiable information (PII), etc., it is vital to keep all AV and IPS signatures up to date. Once files have been encrypted, Dark Power drops a lengthy ransom note as a “readme.pdf”, as seen in Figure 1. ![]() shs, readme.pdf (file name used for ransom note dropped by Dark Power ransomware), ef.exe (file name used for Dark Power ransomware), ntldr, thumbs.db, bootsect.bak, autorun.inf,, boot.ini, iconcache.db, bootfont.bin, ntuser.dat, ntuser.ini, desktop.ini, program files, appdata, mozilla, $windows.~ws, application data, $windows.~bt, google, $recycle.bin, windows.old, programdata, system volume information, program files (x86), boot, tor browser, windows, intel, perflogs, msocache It avoids encrypting files and directories with the following extensions: Once the Dark Power ransomware is executed, it terminates the following processes to encrypt files that are presently in use: However, it is not likely to differ significantly from other ransomware groups. Information on the infection vector used by this group is not currently available. This is a rare ransomware breed in that it was written in the Nim programming language. Severity level: High Dark Power Ransomwareĭark Power is a relatively new ransomware launched in early February 2023. Impact: Encrypts files on the compromised machine and demands ransom for file decryption Impacted parties: Microsoft Windows Users This latest edition of the Ransomware Roundup covers the Dark Power and PayME100USD ransomware. The Ransomware Roundup report aims to provide readers with brief insights into the evolving ransomware landscape and the Fortinet solutions that protect against those variants. On a bi-weekly basis, FortiGuard Labs gathers data on ransomware variants of interest that have been gaining traction within our datasets and the OSINT community. ![]()
