A Russian man has pleaded guilty to hacking US companies and selling access to ransomware groups.
Aleksei Olegovich Volkov went online under the hacker name of chubaka.kor, and worked as an initial access broker (IAB) for the Yanluowang ransomware.
Volkov used various techniques to breach a corporate employee’s account, escalate access to the employer’s network, and then sold that access to other cyber criminals.
According to court documents, between July 2021 and November 2022, Volkov regularly sold access to individuals who later deployed the Yanluowang ransomware.
Investigators tied Volkov to intrusions and subsequent ransomware attacks on seven US companies, including a bank, a telco, and an engineering firm.
Two of the seven victims paid ransoms of $1.5 million in Bitcoin, of which Volkov also got a cut, according to charging documents.
Although court documents don’t mention this, Volkov was charged shortly after the Yanluowang hacked and tried to ransom Cisco in May 2022. It’s unclear if that played any role, but tickling the parent company of the vaunted Talos IR teams might have been a bad decision.
The Yanluowang eventually shuttered operations in November 2022 after it got hacked, and internal chats and its source code were leaked online.
Volkov was eventually arrested in 2024, after he moved to Rome, most likely to escape the complications of Russia’s invasion of Ukraine and the state’s ever-increasing military drafting. He was extradited to the US that same year.
He faces up to 50 years in prison and fines of up to $1 million. A date for the sentencing hearing has not been set yet. He will also have to pay restitution to past victims.

Stalkerware goes down: The number of unique stalkerware products has gone down over the past half-decade. An audit of stalkerware detections on mobile antivirus products found that many stalkerware apps are variations of a small number of products. Unique stalkerware families went down from 20 in 2020 to 17 this year. Detections stayed the same, with a few mobile security products detecting most threats, while others were still very far behind.

New npm malware: Fifty-seven malicious npm packages were discovered and taken down last week. Check out the GitHub security advisory portal for more details.
Ransomware in VS Code extensions: A malicious VS Code extension on the official marketplace tried to deploy ransomware on developer systems. According to Secure Annex, the ransomware appears to have been vibe-coded, hardcoded its encryption key, and appears to have been some sort of joke or experiment.
Ransomware has appeared in the VS Marketplace and makes me worry. Clearly created through AI, it makes many mistakes like including decryption tools in extension. If this makes it into the marketplace through, what impact would anything more sophisticated cause? secureannex.com/blog/ransomv...

Security firm Palo Alto Networks has not linked the zero-day to any spyware vendor or state.
In this sponsored product demo,* Prowler founder and CEO Toni de la Fuente** walks Risky Business host Patrick Gray through the company’s open-source cloud security platform. Toni demonstrates how Prowler can identify and remediate security issues across AWS, Azure, GCP, and Kubernetes. There’s a pointy-clicky GUI interface and a CLI, and both come in handy in different ways. The Prowler platform is completely free and open source, but there is a hosted version you can pay for if you don’t want to run it yourself.*

Risky Business podcasts
In this edition of Seriously Risky Business, Tom Uren and Amberleigh Jack talk about aggressive US cyber operations targeting the Venezuelan government in President Trump’s first term. These were narrowly successful in that they achieved their immediate operational goals, but they didn’t achieve Trump’s broader policy goal of ousting Venezuelan leader Nicolás Maduro.
In this edition of Between Two Nerds, Tom Uren and The Grugq discuss the futility of using aggressive cyber operations to send messages between states.
