Datadog Security Research observed a password spraying campaign from July 24 to August 23, 2026, targeting AWS root user accounts across more than 150 organizations. The attackers used specific Chrome and Firefox user agents and routed traffic through proxy infrastructure with IP addresses flagged as malicious or residential. A key indicator of this campaign is the use of valid root user email addresses, suggesting the attackers either had prior access to such lists or performed brute-force enumeration. No successful authentications were observed, and the motive remains unclear due to the lack of post-compromise activity.

On August 4, 2026, a worm compromised several high-profile npm packages, including keyv, file-entry-cache, and flat-cache, each with around 150 million monthly downloads. The malicious commit (174f6a5) in the keyv package introduced a backdoor designed to propagate to adjacent npm packages, indicating a supply chain attack aimed at widespread distribution. The campaign represents a significant open-source software supply chain compromise with potential for broad impact due to the popularity of the affected packages.

This article details two novel code execution techniques in trusted coding-agent projects that occur after project trust but before the first user prompt, bypassing traditional security controls. In Codex, a malicious project can define a project-scoped Model Context Protocol (MCP) server in .codex/config.toml, causing immediate execution of attacker-controlled processes upon project open. In Claude Code, an attacker can manipulate the PATH environment variable via .claude/settings.json to hijack Git calls and execute a malicious git wrapper script from within the repository. These techniques allow code execution without model interaction or user approval, highlighting the risk of treating project trust as safe.

Recent Linux malware campaigns such as VoidLink, LinkPro, and Atomic Arch leverage eBPF rootkit techniques to evade detection by manipulating kernel-level operations. These rootkits use powerful eBPF helpers like bpf_probe_write_user, bpf_override_return, and bpf_send_signal to hide network connections, suppress enumeration of malicious eBPF programs, and terminate forensic analysis tools. The article highlights that these threats can bypass traditional security tools by tampering with system call outputs and kernel data structures, making early detection at program load time critical.

In June 2026, the threat actor group 'Icarus' conducted a supply chain attack by compromising Klue's backend systems, leveraging dormant OAuth credentials to gain unauthorized access to customer Salesforce and Gong environments. The actor exfiltrated sensitive CRM data including business contacts, price quotes, and sales communications by abusing API queries with stolen OAuth tokens. Klue responded by revoking access and alerting customers, while the actor initiated an extortion campaign using Session Messenger. The attack highlights risks associated with third-party integrations and improper credential lifecycle management.

Threat actors are targeting Salesforce environments by exploiting compromised credentials, OAuth tokens, and misconfigured guest accounts to gain unauthorized access. They perform reconnaissance by querying API endpoints to enumerate resources, discover data objects, and assess API usage limits. This activity is often followed by data enumeration and potential exfiltration, leveraging legitimate authentication mechanisms to blend in with normal traffic. Attackers may use brute-force techniques against weak MFA methods or socially engineer users to approve malicious connected apps.

This article demonstrates a cross-tenant compromise scenario involving Entra agent identities, where an attacker compromises a privileged agent blueprint in one tenant and leverages it to gain unauthorized access to agent identities in another tenant. The attacker adds a credential to a third-party blueprint called 'People Team Agents' and uses it to authenticate as a high-privilege agent, 'Temporary Access Agent', in a subsidiary tenant. This agent has permissions to read user details and reset passwords via Microsoft Graph, which the attacker abuses to set a temporary access pass (TAP) for a Global Administrator account, achieving full compromise of the subsidiary tenant. The attack highlights the risks of trusting third-party agent blueprints with broad permissions across multiple tenants.

Between June 16 and 19, 2026, a phishing campaign targeted AWS users using adversary-in-the-middle (AiTM) techniques to steal console credentials and multi-factor authentication (MFA) codes in real time. The attackers used domains impersonating AWS and SendGrid, hosted on Cloudflare, and delivered phishing emails through legitimate platforms like SendGrid to improve deliverability. The campaign employed a targeted approach with personalized URLs containing encrypted email identifiers, primarily aimed at US-based software engineers and engineering leadership.

GuardDog 3.0 is an open-source security tool designed to detect malicious PyPI and npm packages by analyzing source code for suspicious behaviors. It introduces a new risk scoring engine that evaluates the likelihood of a package being malicious based on attack chain completeness, capability detection, and code sophistication. The tool now uses YARA for more efficient and scalable scanning, replacing Semgrep, and includes built-in sandboxing via nono-py to prevent exploitation during analysis. This release emphasizes improved accuracy, reduced false positives, and defense-in-depth against vulnerabilities in the scanner itself.

The article outlines four new incident response scenarios featured in the Datadog expansion pack of the Backdoors & Breaches card game, designed to simulate real-world cyber threats. These scenarios reflect current trends such as supply chain compromises, cloud credential exposure, AI application vulnerabilities, and CI/CD pipeline attacks. Each scenario demonstrates attacker tactics across initial access, escalation, command and control, exfiltration, and persistence. The purpose is to train teams in detecting and responding to modern cloud and software supply chain threats.

This article discusses the risks associated with Entra agent identities and blueprints, focusing on how compromised or over-privileged agent identities can lead to cross-tenant compromises. It emphasizes securing agent blueprints by restricting high-risk permissions, avoiding the use of secrets, and monitoring for suspicious activity. The guidance includes protective measures, detection strategies, and response steps for compromised agent identities within an Entra ID environment.

Datadog Security Research has observed coordinated campaigns abusing GitHub API to enumerate corporate organizations, repositories, and user accounts. Attackers use ghost accounts, compromised tokens, and custom scraping tools with legitimate-sounding user agents to gather public data and, in some cases, access private repositories. The activity includes reconnaissance via GraphQL and REST endpoints, with rare instances of confirmed data exfiltration. Detection is challenging due to legitimate-looking traffic, but indicators such as suspicious user agents and token types can help identify malicious behavior.

On July 8, 2026, a malicious version (1.20.21) of the npm package @injectivelabs/sdk-ts was published, containing a backdoored module that exfiltrated cryptocurrency wallet mnemonic phrases and private keys. The compromise occurred via a suspicious GitHub commit pushed directly to the main branch, originating from an unfamiliar timezone for the maintainer. Sensitive data was captured during wallet loading and sent via the X-Request-Id HTTP header to a malicious domain designed to mimic a legitimate Injective testnet service. The package was compromised for approximately 49 minutes before being reverted and replaced with a clean version.

A supply-chain attack compromised four popular npm packages under the @asyncapi namespace, affecting over 3 million weekly downloads. The attacker exploited a vulnerable CI pipeline via a malicious pull request to steal credentials for the asyncapi-bot GitHub account, then injected malicious code into the packages. The payloads exfiltrate developer credentials and persist via IDE configuration hooks, leveraging decentralized C2 infrastructure including IPFS and Nostr for resilience.
