Researchers Observe Sub-One-Hour Ransomware Attacks

๐Ÿ”’ Halcyon warns that the Akira ransomware group can complete a full attack lifecycle in under an hour, often exploiting vulnerabilities in internet-facing VPN and backup appliances where multi-factor authentication is absent. The group supplements exploits with credential theft, spearphishing, password spraying and initial access brokers, then exfiltrates data before encryption in a double-extortion model. Akira favors stealth and living-off-the-land tools (FileZilla, WinRAR, WinSCP, RClone) to stage and encrypt data; organizations should adopt layered defenses, harden third-party access, monitor for exfiltration and deploy dedicated anti-ransomware protections.

Ransomware Gangs Use Shanya Packer to Evade EDR Protections

๐Ÿ›ก๏ธ Shanya is a packer-as-a-service used by multiple ransomware gangs to conceal payloads that disable endpoint detection and response (EDR) tools. The service returns a custom, encrypted wrapper that decrypts and decompresses the payload entirely in memory and inserts it into a memory-mapped copy of shell32.dll, avoiding disk artifacts. Sophos telemetry links Shanya-packed samples to Medusa, Qilin, Crytox and Akira, and notes techniques that crash user-mode debuggers and facilitate DLL side-loading to deploy EDR killers.

Fake CAPTCHA Leads to 42-Day Akira Ransomware Compromise

๐Ÿ”’ An employee clicking a fake CAPTCHA (a ClickFix social-engineering lure) on a compromised car dealership site began a 42-day intrusion by Howling Scorpius that delivered the .NET remote access Trojan SectopRAT and ultimately Akira ransomware. Two enterprise EDRs recorded activity but produced few alerts, enabling lateral movement, privilege escalation and the exfiltration of roughly 1 TB. Unit 42 deployed Cortex XSIAM, rebuilt hardened infrastructure, tightened IAM controls and negotiated about a 68% reduction in the ransom demand.

Akira Ransomware Expands to Nutanix AHV and Linux Servers

โš ๏ธCISA, the FBI and international partners warn that the Akira ransomware gang has extended its attack surface beyond Windows, VMware ESXi and Hyperโ€‘V to now target Nutanix AHV and Linux servers. The group exploits exposed VPNs, unpatched network appliances and backup platforms, rapidly exfiltrates data and employs a doubleโ€‘extortion model. Akira uses tunneling tools like Ngrok, remoteโ€‘access abuse (AnyDesk, LogMeIn), and cryptography (ChaCha20 with RSA) to encrypt and leak files. Organizations should prioritize MFA, timely patching, segmented networks and protection of backup and hypervisor consoles.

Akira Bypasses MFA on SonicWall VPNs via Reused Logins

๐Ÿ”Akira ransomware operators are successfully authenticating to SonicWall SSL VPN accounts even when one-time password (OTP) multi-factor authentication is enabled. Arctic Wolf links the logins to credentials and OTP seeds harvested via an improper access control flaw tracked as CVE-2024-40766, and notes attackers can reuse those secrets after devices are patched. Once inside, actors rapidly scan internal networks, harvest backup server credentials, and use techniques such as BYOVD to sideload vulnerable drivers and disable protections. Administrators are urged to install the latest SonicOS (recommended 7.3.0) and reset all SSL VPN credentials immediately.
