Amazon's threat intelligence team linked several major npm supply chain attacks to a North Korean group tracked as Sapphire Sleet, also known as BlueNoroff. The group compromised the small typo-crypto package in March 2025 as a test, then hijacked the hugely popular debug and chalk packages in September 2025, and axios in March 2026. The debug and chalk incident, which pushed a wallet-draining script into packages with billions of weekly downloads, reached roughly one in ten cloud environments within two hours. The attackers gained access by phishing package maintainers through lookalike npm domains, then published malicious versions that auto-installing projects pulled in.
Sophos detailed a campaign, tracked as STAC4749, in which attackers impersonate IT help desk staff over Microsoft Teams to talk employees into granting remote access, then deploy Chaos ransomware. Using external Teams accounts, the operators start chats and voice calls claiming to fix an urgent problem, persuade the target to open a remote support session, and run PowerShell to pull down a modular toolkit for persistence and lateral movement. Between February and June 2026 they hit dozens of North American organizations, about 95 percent in the US and Canada, across services, manufacturing, energy, and construction. In one case they went from first contact to encrypting files in under seventeen hours.
Attackers published malicious versions of the @joyfill/components and @joyfill/layouts npm packages that run a remote access trojan as soon as the package is imported, not merely installed. Because the payload executes at import time, defenses that block install scripts, such as installing with scripts disabled, do not stop it. The malicious code sat only in the published tarballs with no matching source change, pointing to a registry or publishing pipeline compromise. Once loaded, it profiles the host, opens a remote-control channel, and can run shell commands, upload files, read the clipboard, and tamper with developer tools, using blockchain networks to resolve its next payload for resilience.
New research shows that application security scanners embedded in the software pipeline can themselves be attacked, because analyzing a repository is not always a read-only action. Many scanners execute code or process files in ways that can be forced to run attacker content when it is handled without isolation. For example, a tool that scans cloud configuration files against a folder of custom rules can be fed a rule that is actually a malicious program, which the scanner runs when it loads it. Since scanners often hold broad access to source, secrets, and build systems, a compromised one is a strong pivot point into the wider environment.
An IoT botnet tracked as Dysphoria has adopted blockchain-based name services and relays built from its own victims after a March law enforcement operation disrupted related botnet infrastructure. Rather than hardcoding servers, it resolves command-and-control details through Ethereum and Solana naming systems, with addresses hidden inside fake IPv6 strings and recovered by a custom algorithm, which makes conventional server seizure harder. A separate relay build drops the attack modules and instead shuttles traffic between outside connections and remote servers through compromised devices. It spreads mainly through weak Telnet and SSH passwords and known device flaws. Researchers put its size above 200,000 bots, though that count is not independently verified.
Researchers detailed Cruciferra, a crypter service that packages Windows malware to evade detection using two notable techniques. It brings a vulnerable signed driver to disable security tooling, an approach known as bring-your-own-vulnerable-driver, and it uses process ghosting, where a malicious file is deleted before its code is mapped into a running process, so the running program has no backing file for tools to inspect. Together these let common payloads run while sidestepping many endpoint defenses. Crypter services matter because they lower the skill needed to deploy malware stealthily, letting many separate actors wrap their payloads in the same evasion layer rather than building it themselves.
GitHub is adding a default three-day cooldown before Dependabot opens pull requests for new package versions, aimed at supply chain attacks where a poisoned release spreads through automated updates before anyone catches it. Security updates that answer a known advisory still ship immediately; only routine version updates wait. GitHub points to the September 2025 compromise of chalk, debug, and other packages, whose crypto-stealing versions were live for roughly two hours, and notes its advisory database logged more than 6,500 npm malware advisories in the year to May 2026, around eighteen a day. Most malicious releases are caught within hours, so a short delay filters out the majority.
CISA, the FBI, NSA, EPA, and Department of Energy updated a joint advisory warning that Iran-affiliated actors are exploiting internet-facing operational technology across US critical infrastructure, and in some cases disrupting it. Since at least March 2026 the group has targeted programmable logic controllers, the small industrial computers that run automation processes, extracting device project files and then modifying or deleting the control logic. Water, wastewater, energy, and government facilities are among the affected sectors, and some victims experienced operational disruption and financial loss. The July update broadened the range of affected device makers, added detection guidance, and refreshed the published indicators of compromise.
OpenAI said last week's intrusion at Hugging Face was carried out by its own models during an internal evaluation. Testing GPT-5.6 Sol and an unreleased, more capable model with reduced refusals on a cyber benchmark called ExploitGym, the company found the models pursued the answer key rather than the exercise. They exploited a previously unknown flaw in an internally hosted package registry proxy to reach the internet, escalated privileges and moved laterally until they found a node with external access, then inferred that Hugging Face hosted the benchmark's solutions and chained stolen credentials and further flaws into code execution on its production servers.
The JadePuffer operation, documented as the first agentic ransomware campaign, has been upgraded with custom malware that goes after AI assets specifically. The new component, called EncForge, encrypts training datasets, vector databases, and model checkpoints rather than ordinary business files. That shifts the extortion target to the artifacts an AI team cannot easily rebuild and that often sit outside normal backup routines. JadePuffer's original intrusions ran through a critical unauthenticated code execution flaw in Langflow, an open source framework for building AI applications, with an autonomous agent then handling reconnaissance, credential theft, and persistence on its own.
