Note: In 2017, security researchers identified a ransomware variant that appended an identical file extension (.akira) to encrypted files; however, this variant is not related to the Akira ransomware group.
We assess that Akira is likely an opportunistic ransomware group due to their victimology and negotiation tactics. In nearly every incident response case Arctic Wolf investigated, the threat actors claimed that they needed time to review the exfiltrated data to determine a ransom demand.
Identifying code overlap between different ransomware variants typically allows analysts to attribute activity back to a specific group due to ransomware source code being tightly guarded by threat actors. However, with the Conti source code leak, multiple threat actors leveraged the code to develop or modify their own code base making attribution back to Conti threat actors much more difficult.
Although both ransomware variants differ, Akira ransomware does bear some semblance to Conti ransomware. Akira ignores the same file types and directories as Conti ransomware and has functions that are similar. Akira also used the ChaCha algorithm to encrypt files, which was implemented similarly to the one used by Conti ransomware.
On June 29, 2023, however, Avast released a decryptor for Akira ransomware that victim organizations can use to decrypt files. Based on current intelligence, the threat actors have modified the encryption routine since the decryptor was published, indicating that it may not work if files were encrypted after June 29th.
Although cryptocurrency can be acquired without attribution back to the buyer, it is not completely anonymous. Transactions between cryptocurrency wallets are published to the blockchain ledger which is publicly viewable via a blockchain explorer.
By leveraging known threat actor cryptocurrency wallet addresses, we are able to conduct pattern analysis of the transactions and discover additional wallet addresses. In some instances, we have observed cryptocurrency address reuse between threat groups, indicating the individual controlling the address or wallet has either splintered off from the original group or is working with another group at the same time.
By following transactions discovered during blockchain analysis, we can tie individual groups together with higher fidelity based on transactions to and from known threat actor-controlled cryptocurrency addresses. Tracking ransom payments to Akira allowed Arctic Wolf Labs to identify transactions to Conti-affiliated addresses. The same analysis method allowed our team to identify connections between the Karakurt extortion group, Diavol, and the Conti ransomware group in 2022.
