In the event you’re a Bare Safety Pocast listener, you could keep in mind, again in March 2022, that we spoke about a convicted cybercriminal from Canada by the title of Sebastien Vachon-Desjardins.
By all accounts, he was a part of a number of so-called Ransomware-as-a-Service (RaaS) gangs, resembling REvil and NetWalker, the place the precise ransomware attackers act as “associates” for the core ransomware creators, in return for handing over an AppStore-like or Google Play-like 30% reduce of each blackmail cost they extort.
Merely put, the core gang members create the malware samples, run the darkweb servers that deal with the “negotiations” with victims, and gather the extortion funds…
…whereas the associates deal with breaking into victims’ networks, mapping them out, and lining up the ultimate assault during which as many computer systems on the community as doable have their information scrambled on the identical time.
The “enterprise principle”, if we are able to name it that, is that by taking 30% of each profitable assault, the core criminals grow to be extraordinarily rich certainly, however maintain a low profile away from the network-cracking limelight.
On the identical time, by handing 70% to their “associates”, they encourage these co-conspirators to make every assault as debilitating as doable, probably rising the quantity that victims can finally be squeezed into paying to get their enterprise operating once more.

The background
Vachon-Desjardins had been a federal authorities employee within the Canadian Capital Area (he comes from Gatineau in Quebec, immediately throughout the river from the federal capital Ottawa in Ontario).
He appears to have determined that becoming a member of the cybercrime underworld could be far more profitable than his authorities job, and evidently did certainly rack up a small fortune in unlawful earnings…
…till he was recognized, arrested and prosecuted in Canada.
After being sentenced to almost seven years in a Canadian jail, he was then extradited to Tampa, Florida within the US, to face 4 federal prices there:
- Conspiracy to Commit Pc Fraud
- Conspiracy to Commit Wire Fraud
- Intentional Injury to a Protected Pc
- Transmitting a Demand in Relation to Damaging a Protected Pc
The selection of Tampa for his trial was as a result of a recognized sufferer of considered one of his “NetWalker” ransomware assaults relies there.
Vachon-Desjardins has now pleaded responsible to all 4 prices, with the plea settlement (because of The Register for importing a replica of the court docket doc) explaining:
The NetWalker Ransomware was a particular sort of malicious software program (malware) that was used to compromise and prohibit entry to a sufferer’s pc community in an effort to extort a ransom. Conspirators used NetWalker not solely to encrypt sufferer information, but additionally used the malware to steal delicate information from victims. If a sufferer didn’t pay the ransom, conspirators would refuse to decrypt sufferer information and would publish the delicate, stolen information on-line. The stolen information was typically printed on a darkish net web site named “the NetWalker Weblog,” which existed for the first goal of facilitating the publication of stolen sufferer information.
NetWalker operated as ransomware-as-a-service (“RaaS”), that includes Russia-based builders and associates who resided everywhere in the world. Beneath the RaaS mannequin, builders had been accountable for creating and updating the ransomware, and making it accessible to associates. Associates had been accountable for figuring out and attacking high-value victims with the ransomware. After a sufferer paid, builders and associates cut up the ransom. Sebastien Vachon-Desjardins was some of the prolific NetWalker Ransomware associates.
SophosLabs has analysed the NetWalker ransomware intimately, because of a stash of recordsdata recovered by our risk response crew throughout an ransomware incident investigation in 2020:
The plea deal additionally notes that:
On or about January 27 and 28, 2021, the Royal Canadian Mounted Police executed search warrants at Vachon-Desjardins’ dwelling and on secure deposit containers held by Vachon-Desjardins at Nationwide Financial institution, Gatineau, Quebec.
Throughout these searches, legislation enforcement seized, amongst different property , all bitcoin contained within the defendant’s BTC Pockets 3Pxki6pFFKC12YSn8JtDs3ZrEg3pFTHnHd.
This seized bitcoin was derived primarily from ransom funds paid by victims of NetWalker Ransomware assaults.
The quantity seized was just below BTC 720, price about US$23 million in early 2021, and nonetheless price about US$14 million immediately.
That wasn’t all, nevertheless, with the court docket doc stating:
Regulation enforcement recognized and seized copies of the server that operated because the backend, or internal-facing, server of the NetWalker Tor Panel and the NetWalker Weblog. This server contained detailed transactional info as to the NetWalker builders and associates. The transactional information revealed that throughout the course of the conspiracy, roughly 100 associates had been lively, and victims had paid roughly 5058 bitcoin in ransoms (an approximate complete of US$40 million based mostly on the worth of bitcoin on the time of every transaction).
These information additionally tied Vachon-Desjardins to the profitable extortion of roughly 1864 bitcoin in ransoms (an approximate complete of US$21.5 million based mostly on the worth of bitcoin on the time of every transaction) from dozens of sufferer corporations internationally, together with [the victim in Tampa, Florida].
What subsequent?
As Chester Wisniewski put it within the March 2022 podcast:
Sebastien is quickly “on mortgage” to the Individuals, to allow them to punish him, however when he comes again, he nonetheless has to face his sentence right here in Canada.
The wire fraud offence alone carries a most sentence of 20 years, however we’re assuming that the court docket will impose a lighter sentence on account of the plea deal being signed.
The plea settlement makes it clear that “[the] defendant is pleading responsible as a result of [he] is the truth is responsible.”
And a part of the deal contains that the “defendant agrees to cooperate totally with the US within the investigation and prosecution of different individuals, […including] a full and full disclosure of all related info, together with manufacturing of any and all books, papers, paperwork, and different objects in defendant’s possession or management.”
In different phrases, Vachon-Desjardins is now anticipated to spill the beans, and rat out his former pals within the ransomware scene.
