Akira Ransomware

Filestore.Fortinet November 13, 2025

First detected in March/April of 2023, this ransomware group primarily focuses on small to medium-sized businesses, driven by financial motives. Like other notorious ransomware, Akira utilizes familiar tactics such as Ransomware-as-a-Service and double extortion to maximize their profits. The ransomware uses virtual private network (VPN) service without multifactor authentication (MFA)- mostly using known Cisco vulnerabilities CVE-2020-3259 and CVE-2023-20269, external-facing services such as Remote Desktop Protocol, spear phishing, and the abuse of valid credentials. These credentials are typically acquired through brute force attacks or obtained from the dark web. Once inside, threat actors deploy various tools and malware to conduct reconnaissance, dump credentials, exfiltrate data, and move laterally within the network. Initial iterations of the Akira ransomware variant were coded in C++ and encrypted files with a .akira extension. However, from August 2023 onwards, certain Akira attacks transitioned to utilizing Megazord, featuring Rust-based code that encrypts files with a .powerranges extension. Akira threat actors persist in employing both Megazord and Akira, including the newer version, Akira_v2.
