Our verdict on KISA LooCipher Ransomware Decryption Tool

KISA LooCipher Ransomware Decryption Tool is a free downloadable utility from the Korea Internet & Security Agency for people trying to recover files encrypted by LooCipher ransomware. It is a narrowly scoped recovery option rather than a general-purpose ransomware tool: its stated target is LooCipher, and its manual describes a Windows executable workflow. That makes it relevant when the affected files match this strain, but not a fit for incidents involving other ransomware.

The recovery process is specific and file-led. KISA's manual says to remove the malicious code before recovery, then drag an infected file onto LooCipher_decryptor.exe. The listed input extensions are JPEG, JPG, PDF, DOCX, PPTX, XLSX and PNG. The tool analyzes a file to recover a decryption key, saves that key in key.txt, and uses it to restore files; KISA recommends backing up encrypted files first. This process will suit users comfortable following a manual and handling files through a Windows executable, but it is not described as a broad scan or automated incident response workflow.

KISA states the tool is provided free of charge, so there are no paid tiers to weigh against added capabilities. The trade-off is its strict strain focus and command-line component: decryption code runs in CMD, which may be less approachable than a guided graphical process. Choose it when LooCipher is the confirmed problem and the listed file types are relevant. Look for a different recovery route if the ransomware strain is unknown or not LooCipher, or if the affected platform and process do not match the manual's Windows executable workflow.
