Scientists at Blackberry have identified a new world-wide marketing campaign that the business believes demonstrates the hallmarks of an as-a-services attack campaign: it employs a mixture of elaborate, bespoke malware and inconsistent, but deliberate, options of targets.
“We’re hoping by publishing, the neighborhood can enable us choose up the breadcrumbs,” reported Tom Bonner, distinguished risk researcher at Blackberry. “We’re not guaranteed what the endgames are.”

CostaRicto, a name Blackberry derived from a task title in the malware, has attacked international locations in each individual continent, help you save South The usa and Antartica. When, the comprehensive array of industries associated in the attacks are remaining stored secret for client protection good reasons, Bonner claims they’ve hit targets ranging from banking to retail. Based mostly on targeting alone, it may feel like a common criminal offense operation. Point out teams tend to concentrate on precise industries, areas and targets of distinct benefit.
But, said Eric Milam, vice president of research operations, it doesn’t feel like criminal offense is the finish intention.
“Everything place in position is for safe communications and facts transfer,” he said. “They had obtain lengthy adequate that if they were heading to deploy ransomware, they would have deployed ransomware. If the goal was cash, they would have carried out one thing that’d gain dollars by now.”
The two-stage malware utilized by CostaRicto is unusually elaborate for a smash-and-grab criminal operation. The team designed its very own virtual device to operate its personal bytecode. The malware is fileless. There is not a great deal of off the shelf tooling.
“It appears to be like like exfiltrating info is the place, but we’re looking at some of the customers they’ve attacked and imagining, ‘really?’” explained Bonner.
Milam agreed: “One of the customers, from a vertical we did not involve in the report, appears to be like a vertical that would be ransomed immediately.”
One notable tidbit from the code offering some limited insight into its creators was the remote accessibility trojan, “SombRAT,” which appears to be a reference to the Overwatch movie recreation character Sombra. That does not limit the scope of the attacker Russian intelligence famously coopted a identify for Dune.
CostaRicto hardcoded many spoofed domains into its malware, which include a person for sbibd[.]net, which may well be a reference to the Point out Financial institution of India, Bangladesh. Aspects of its infrastructure appeared to share an IP handle with a web page utilized by APT 28, but that could be a outcome of a poorly run webhosting organization alternatively than relationship to the team.
For defenders, Bonner stated, the message is very simple and “boring”: use the exact same superior cleanliness you’d use to defend from any attack, update all the security solutions and include the Yara procedures.
For researchers, he mentioned, start out picking up individuals breadcrumbs. “We could have accomplished six months far more of investigation on this. We assumed it would be best to get this out immediately.”
