2025-03-26For payment. Once executed, it stays hidden for three days before it activates its file encryption capabilities. The time counter is stored in the .kernel_time file. On its trigger date, it connects to one of six sites hosted in the TOR network in order to download a ransom text message and RSA public key. The connection to the TOR network is made through public TOR2WEB gates.Figure 4 - A captured request by OSX/Filecoder.KeRanger.A to a C&C serverThe OSX/Filecoder.KeRanger.A Trojan enumerates all the files in the /Users and /Volumes folders and makes an attempt to encrypt them. It uses strong cryptography for the encryption – the malware randomly selects a 256-bit key for the AES algorithm, encrypts the file, then encrypts the AES key with the RSA algorithm and saves the encrypted blob to the file. Thus, different files have different encryption keys.Figure 5 - File extensions encrypted by KeRangerThe ransomware might encrypt more than 300 file extensions, including documents, photos, videos, archives, etc. When a file is encrypted its file extension changes to .encrypted. The malware creates a text file demanding a ransom in all folders with encrypted files. Note that the wording of the message is downloaded from the C&C server. That means it can be modified by the attacker at any time, allowing the attackers to change the amount they demand in ransom, among other things. The message isn’t displayed proactively to the victim.Figure 6 - The ransom demand text created by OSX/Filecoder.KeRanger.A TrojanIndicators of Compromise (IoC)SHA-1:5F8AE46AE82E346000F366C3EABDAFBEC76E99E9 FD1F246EE9EFFAFBA0811FD692E2E76947E82687C&C-servers:lclebb6kvohlkcml.onion[.]linklclebb6kvohlkcml.onion[.]nubmacyzmea723xyaz.onion[.]linkbmacyzmea723xyaz.onion[.]nunejdtkok7oz5kjoc.onion[.]linknejdtkok7oz5kjoc.onion[.]nu
2025-04-2431 May 2017Today, ESET announced the release of a AES-NI decryption tool for victims whose data has been encrypted by Win32/Filecoder.AESNI.B and Win32/Filecoder.AESNI.C (also known as XData). The AES-NI decryption tool is based on keys recently released via Twitter and a help forum for ransomware victims. “The decryption tool works for files encrypted by the offline RSA key used by the AES-NI variant B, which adds the extensions .aes256, .aes_ni, and .aes_ni_0day as well as for the so-called XData variant adding .~xdata~ to the affected files”, explains Ondrej Kubovič, Security Specialist at ESET. Victims who still have their encrypted files can now download the decryptor from ESET’s utilities page. For additional information on how to use the tool and detailed information on specific cases where the decryptor can’t help, please refer to ESET Knowledgebase. More background information on what appears to be the malware creators’ demise, and how to protect yourself from ransomware, can be found at ESET’s official blog, WeLiveSecurity.
