New Interrupt Injection Attack Bypasses Spectre v2 Defenses on Intel and AMD CPUs
In August 2026, researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) disclosed a novel attack technique named 'Interrupt Injection.' This method exploits a timing vulnerability in Intel and AMD CPUs, allowing unprivileged Linux programs to inject hardware interrupts precisely between the processor's branch predictor sanitization and its subsequent use by the kernel. This re-poisoning of the branch predictor can lead to speculative execution vulnerabilities, enabling attackers to leak arbitrary kernel memory. Demonstrations on AMD Zen 2 processors running Linux 6.14 with default Spectre v2 mitigations showed data leakage rates of 5.47 bytes per second with 91.97% accuracy, sufficient to extract sensitive files like /etc/shadow in multiple attempts. The attack requires only local code execution without elevated privileges, posing significant risks to shared systems utilizing affected processors. This incident underscores the persistent challenges in securing speculative execution mechanisms within modern CPUs. Despite existing mitigations for Spectre v2 vulnerabilities, the discovery of Interrupt Injection highlights the need for continuous vigilance and adaptation in hardware and software defenses. Organizations must stay informed about emerging threats and ensure timely application of patches to protect sensitive data from sophisticated side-channel attacks.

Decade-Long Vulnerability in Microsoft Secure Boot Uncovered
In July 2026, researchers discovered a critical vulnerability in Microsoft's Secure Boot, a feature designed to protect devices from firmware infections. This flaw, present for 13 of Secure Boot's 14-year existence, allowed attackers to bypass protections using outdated, signed firmware images known as shims. These shims, some dating back to 2013, remained signed by Microsoft despite known defects, enabling unauthorized code execution during system boot and facilitating persistent malware infections. This incident underscores the importance of rigorous certificate management and timely revocation processes. The prolonged exposure highlights potential oversight in Microsoft's security protocols, emphasizing the need for continuous monitoring and updating of security measures to prevent similar vulnerabilities.

Outdated UEFI Bootloaders Pose Security Risks
In July 2026, researchers identified 11 outdated UEFI shim bootloaders, all signed by Microsoft, that remained trusted components within the Secure Boot framework. These bootloaders, versions 0.9 and earlier, lacked modern security protections and could be exploited by attackers to bypass Secure Boot, allowing the execution of malicious code during the boot process and establishing persistent access below the operating system level. Microsoft addressed the issue by revoking these vulnerable bootloaders in June 2026 through Secure Boot revocation updates. However, systems that have not applied these updates remain susceptible to boot-level attacks, as the revoked shims continue to be trusted on unpatched machines. This incident underscores the critical importance of timely firmware updates and the need for organizations to maintain vigilance over the security of their boot processes to prevent potential exploits.

LabubaRAT: A New Rust-Based RAT Disguised as NVIDIA Software
In July 2026, cybersecurity researchers identified LabubaRAT, a previously undocumented Rust-based remote access trojan (RAT) that masquerades as NVIDIA software to infiltrate Windows systems. The malware establishes a persistent foothold, enabling attackers to profile the host, identify security tools, execute commands, transfer files, capture screenshots, and proxy traffic through the compromised system. LabubaRAT employs multiple communication methods, including HTTPS, WebView2, and DNS tunneling, to maintain access even if one pathway is detected and blocked. The attack initiates with an executable named "nvidia-sysruntime.exe," which impersonates NVIDIA's container runtime toolkit. Instead of hard-coding its command-and-control (C2) information, the malware accepts runtime configurations via command-line arguments, allowing operators to define parameters such as server details and polling intervals. This flexibility enables the reuse of the same binary across different infrastructures and campaigns without modification. Once deployed, LabubaRAT conducts discovery operations to inventory installed web browsers and security products, gathering information on the host's environment to tailor its functionality accordingly. The malware's capabilities include command execution, PowerShell and JavaScript execution, screenshot capture, file upload and download, archive handling, and SOCKS5 proxy support. These features provide attackers with comprehensive control over the infected host, facilitating data exfiltration and further malicious activities. The emergence of LabubaRAT underscores the evolving sophistication of malware designed to evade detection by masquerading as legitimate software. Its use of Rust, a language known for its performance and safety features, highlights a trend among threat actors to adopt modern programming languages to develop more robust and stealthy malware. Organizations must remain vigilant and implement robust security measures to detect and mitigate such threats.

ESET Uncovers Vulnerable Microsoft-Signed UEFI Shims Allowing Secure Boot Bypass
In July 2026, ESET researchers identified 11 outdated, Microsoft-signed UEFI shim bootloaders vulnerable to Secure Boot bypasses. These shims, versions 0.9 and below, allow attackers to execute untrusted code during system boot, potentially deploying malicious UEFI bootkits. Exploitation isn't limited to systems with the affected software installed; attackers can introduce these vulnerable shims to any UEFI system trusting the Microsoft Corporation UEFI CA 2011 certificate. Microsoft addressed this by revoking the vulnerable shims in its June 9, 2026 Patch Tuesday update. ([globenewswire.com](https://www.globenewswire.com/news-release/2026/07/14/3326630/0/en/eset-research-discovers-vulnerable-uefi-shims-undermining-devices-secure-boot.html?utm_source=openai)) This incident underscores the critical need for organizations to regularly update and monitor bootloader components. The discovery highlights the risks associated with outdated firmware and the importance of timely patch management to maintain system integrity.
