LG Energy Solution, a major South Korean battery manufacturer, experienced a ransomware attack that disrupted operations at one of its overseas facilities. The company confirmed that the incident was isolated to a single location, with headquarters and other facilities remaining unaffected. After implementing recovery measures, the impacted facility resumed normal operations, and ongoing security investigations are underway to assess the full scope of the breach.
The Akira ransomware gang claimed responsibility for the attack, stating they exfiltrated 1.7 terabytes of sensitive data, including corporate documents and employee databases. The FBI recently highlighted Akira's activities, noting the group has extorted over $244 million from various sectors, including manufacturing. The incident underscores the increasing targeting of battery manufacturers by ransomware groups, as seen in previous attacks on industry peers.

3 events from the most recent confirmed update back to the earliest known activity.
AhnLab's ASEC blog included the Akira group's threat to leak data allegedly stolen from LG Energy Solution in its Week 3 November 2025 ransomware and dark web roundup. This reflected public reporting and monitoring of the incident on cybercrime channels.
LG Energy Solution said a ransomware attack targeted one of its overseas facilities, while stating that its headquarters and other sites were not affected. The company said the impacted facility had resumed normal operations after recovery measures and that a security investigation was ongoing.
The Akira ransomware group posted that it had stolen 1.7 TB of data from a South Korean lithium-ion battery and energy solutions company identified in reporting as LG Energy Solution, and threatened to leak the data. The claimed haul included corporate documents and employee database information.

Researchers and incident responders reported that **Akira ransomware** affiliates used a repeatable intrusion playbook built around stolen VPN credentials and exploitation of internet-facing appliances, including Fortinet flaws `CVE-2019-6693` and `CVE-2022-40684` and Cisco ASA/FTD flaw `CVE-2023-20269`. Recovered attacker infrastructure exposed direct evidence of reconnaissance, credential theft, and exfiltration activity, including decrypted Fortinet configurations, password-protected RAR archives containing stolen victim data, and command history showing downloads from a public-facing victim server. Investigators said the operators relied heavily on legitimate administration tools such as AnyDesk, TeamViewer, OpenSSH, MobaXterm, PowerShell, WMI, Impacket, WinSCP, FileZilla, and Cloudflared, while moving laterally through RDP and SMB and attempting to disable defenses, erase evidence, and destroy Veeam backups before encryption. Analysis of Akira’s malware and victim activity showed a **double-extortion** model that spans both Windows and Linux environments. The Linux variant supports selective path targeting, network-share encryption, partial encryption, file exclusions, and multithreaded execution using AES and RSA, dropping `akira_readme.txt` ransom notes with Tor-based contact details. Reporting also tied Akira to broad U.S.-focused targeting across sectors and suggested some operators may overlap with other ransomware-as-a-service programs, including possible links to Snatch. The group’s activity continued to affect organizations such as Texas-based **CF Supply**, where attackers were reported to have compromised corporate data that could include client project records, personal information, contracts, and agreements.

U.S. and European cyber authorities released an updated joint advisory detailing the latest tactics, techniques, and procedures (TTPs) used by the Akira ransomware group, which has rapidly become one of the most consequential ransomware threats targeting critical infrastructure and businesses worldwide. The advisory, supported by agencies including CISA, FBI, DoD Cyber Crime Center, HHS, Europol, and law enforcement from France, Germany, and the Netherlands, highlights Akira’s evolution, its double-extortion model, and its targeting of sectors such as manufacturing, education, IT, healthcare, financial, and agriculture. Akira actors exploit vulnerabilities in edge devices, backup servers, and VPN products—including SonicWall (CVE-2024-40766), Cisco, Windows, VMware ESXi, and Veeam—using techniques like credential theft, brute-force attacks, and initial access brokers. They employ remote management tools (AnyDesk, LogMeIn) for defense evasion, uninstall endpoint detection and response (EDR) systems, and leverage custom malware such as POORTRY for privilege escalation. As of late September 2025, Akira has extorted over $244 million in ransom payments, primarily from small- and medium-sized businesses. The group is associated with other threat actors such as Storm-1567, Howling Scorpius, Punk Spider, and Gold Sahara, and may have links to the disbanded Conti group. The FBI ranks Akira among the top five ransomware variants it investigates, citing its significant financial and operational impact on victims. The advisory provides updated indicators of compromise (IOCs), detection methods, and a list of newly exploited vulnerabilities to help organizations defend against Akira’s ongoing campaigns.

Sophos reported that **Akira** has become a major threat to small and medium-sized organizations across Europe, North America, and Australia, hitting sectors including government, manufacturing, technology, education, consulting, pharmaceuticals, and telecommunications. The group commonly gained initial access through unauthorized logins to **Cisco ASA SSL VPN** and **Cisco AnyConnect** systems that lacked MFA, and in some cases exploited `CVE-2023-20269` and Veeam `CVE-2023-27532`. Researchers said Akira operators routinely stole credentials, moved laterally, established persistence, and attempted to evade defenses before either encrypting systems or stealing data for extortion. Sophos said Akira shifted notably toward **extortion-only** operations beginning in late 2023, exfiltrating data without always deploying ransomware. During intrusions, the actors dumped **LSASS**, extracted `NTDS.dit` and `SYSTEM` hives, targeted Veeam, browser, and KeePass credentials, and used tools including **Mimikatz, AdFind, Advanced IP Scanner, RDP, SMB, wmiexec, PsExec, AnyDesk, WinRAR, rclone, and MEGA**. The report also identified a previously unreported backdoor, **`crome.exe`**, communicating with `170.130.165[.]171`, alongside repeated efforts to disable Sophos and Microsoft Defender protections. When encryption was used, Akira deployed binaries such as `w.exe`, `Lck.exe`, `1.exe`, and `locker.exe`, appended the `.akira` extension, dropped `akira_readme.txt`, deleted Volume Shadow Copies, and in one case encrypted about 65,000 files on a server.
