Software supply-chain attacks, in which hackers corrupt widely used applications to push their own code to thousands or even millions of machines, have become a scourge, both insidious and potentially huge in the breadth of their impact. But the latest major software supply-chain attack, in which hackers who appear to be working on behalf of the North Korean government hid their code in the installer for a common VoIP application known as 3CX, seems so far to have had a prosaic goal: breaking into a handful of cryptocurrency companies.
Researchers at Russian cybersecurity firm Kaspersky today revealed that they identified a small number of cryptocurrency-focused firms as at least some of the victims of the 3CX software supply-chain attack that’s unfolded over the past week. Kaspersky declined to name any of those victim companies, but it notes that they’re based in “western Asia.”
Security firms CrowdStrike and SentinelOne last week pinned the operation on North Korean hackers, who compromised 3CX installer software that’s used by 600,000 organizations worldwide, according to the vendor. Despite the potentially massive breadth of that attack, which SentinelOne dubbed “Smooth Operator,” Kaspersky has now found that the hackers combed through the victims infected with its corrupted software to ultimately target fewer than 10 machines—at least as far as Kaspersky could observe so far—and that they seemed to be focusing on cryptocurrency firms with “surgical precision.”

“This was all just to compromise a small group of companies, maybe not just in cryptocurrency, but what we see is that one of the interests of the attackers is cryptocurrency companies,” says Georgy Kucherin, a researcher on Kaspersky’s GReAT team of security analysts. “Cryptocurrency companies should be especially concerned about this attack because they are the likely targets, an ..
