Tracking down ransomware: CipherTrace helps McAfee track NetWalker funds
On August 3, cybersecurity company McAfee released new research showing the activities of NetWalker—Ransomware toocap has more than 2,795. collected bitcoin by operating a ransomware-as-a-service (RaaS) model. Using CipherTrace Inspector, McAfee was able to track the data NetWalker Ransomware transactions to track the coins and uncover information about the revenue sharing system that helped multiply the malware to make it as profitable as possible.

To further increase your success, NetWalker Operators used darknet forums to give tips on how to best spread the malware.
With CipherTrace Inspector, McAfee analysts tracked BTC addresses extracted from a Screenshot of four done NetWalker Ransomware payments on a RaaS darknet market. found listing. These screenshots only partially showed BTC addresses, but CipherTrace Inspector Autocomplete was able to easily determine the full addresses so that McAfee analysts could further investigate the ransomware scheme. These addresses were:
Analysts were then able to identify the ransomware actors consolidated Funds from the four Addresses listed above to the following two addresses under the NetWalker RaaS operator Control:
RaaS payments are routinely split
An analysis of these two additionally Addresses revealed incoming transactions from multiple deposit addresses belonging to the ransomware scheme. Some of the incoming transactions were split across four different addresses, suggesting a RaaS model as ransom payments are split between RaaS operators and the partner who caused the infection. The divisions found through A blockchain – the technology that underlies Bitcoin and other technologies. More Analytics matched the R.aaS fees NetWalker operator advertised in darknet forums, with approximately 20th% Goes to RaaS operator.
NetWalker RaaS payments are routinely split according to the RaaS Profit Sharing Agreement. Splitsting Transactions Right this way shows a much more organized one Business model with more sophisticated BTC movements.

The addresses currently apparently used as cold storage by these operators are also SegWit Addresses. This transition in SegWit could indicate that it is them either Use a new hardware wallet to manage their BTC or just an indication of the desire for cheaper transactions to let the operation scale while Transaction costs low.

Why It M.flatters
The development of ransomware-as-a-service operations like NetWalker has become a lucrative business for threat actors. Fears of foreign interference in the US presidential election are growing, and federal officials are warning that ransomware could be a tool used by opponents. “From the point of view of trust in the system, I think it is much easier to disrupt a network and prevent it from operating than to change voices,” said Adam Hickey, deputy assistant attorney general for the Department of Justice, in an interview. It is critical not only to track ransomware revenues to find and stop the operators, but also to harden the systems and educate the public on how these compromises occur to prsurgically mitigate Disorder.
