Threat Actors Target Semiconductor Companies with Ongoing Zero-Day Exploit Campaigns

Semiconductor companies are facing growing threats from cyber adversaries leveraging the darknet to exchange stolen intellectual property, exploit zero-day vulnerabilities, and sell unauthorized access to corporate environments.

This new wave of attacks, enabled by highly organized cybercrime groups, ransomware gangs, and nation-state actors, showcases the strategic importance of the semiconductor industry in global technology and security.

Strategic Target for Cybercriminals and State-Sponsored Actors

Semiconductors, the foundation of modern electronics, power critical technologies, from artificial intelligence and autonomous vehicles to defense systems and the Internet of Things.

As key enablers of innovation, semiconductor companies are uniquely vulnerable to cyberattacks that target their intellectual property, supply chains, and operational infrastructure.

Advanced chip designs and fabrication techniques, which are worth billions, make these companies lucrative targets for advanced persistent threat (APT) groups seeking to steal proprietary technologies.

Nation-state actors, in particular, orchestrate cyberespionage campaigns to achieve technological dominance and military superiority.

Additionally, the semiconductor industry’s reliance on an intricate global supply chain exposes it to significant vulnerabilities.

Cybercriminals exploit these weak links, as evidenced by attacks such as the SolarWinds and Kaseya incidents, where third-party compromises led to widespread breaches.

With high costs associated with production downtime, attackers frequently deploy ransomware or destructive malware to disrupt manufacturing processes, extort money, or cripple critical infrastructure.

The Darknet’s Role in Semiconductor Cyberattacks

The darknet plays a pivotal role in enabling cyber threats against semiconductor firms.

Threat actors populate hidden forums and marketplaces, such as RAMP and BreachForums, to trade compromised credentials, session tokens, and exploits that can bypass multifactor authentication (MFA).

Initial Access Brokers (IABs) are particularly active in this ecosystem, selling pre-compromised credentials for remote desktop protocols (RDP), VPNs, and enterprise tools like Citrix.

According to the Report, these access points are often handed over to ransomware groups, including LockBit, BlackCat (ALPHV), and RansomEXX, which specifically target semiconductor manufacturers.

The darknet is also a marketplace for zero-day vulnerabilities security flaws that are unknown to the affected technology owner and lack immediate patches.

In the semiconductor sector, zero-day exploits targeting ICS/SCADA systems, firmware, and chip design toolchains are highly coveted.

Rare cases of malicious firmware vulnerabilities in semiconductor manufacturing equipment, such as ASML lithography systems and ARM-based architectures, have been observed in targeted attacks.

Furthermore, hardware-level threats loom large for semiconductor companies. Adversaries embed malicious firmware or backdoors into chips before deployment, posing risks to critical infrastructure dependent on compromised components.

Tools like Electronic Design Automation (EDA) software used in chip manufacturing are also becoming targets for attackers seeking to inject vulnerabilities at the design stage.

Recent years have witnessed several significant breaches within the semiconductor industry, underscoring the sector’s susceptibility to darknet-driven threats.

In 2022, Lapsus$ attacked NVIDIA, stealing proprietary GPU designs, employee credentials, and code-signing certificates, which were later leaked online.

These certificates were used to develop malicious drivers, amplifying the threat.

In a separate incident in 2023, LockBit ransomware infiltrated the supply chain of TSMC (Taiwan Semiconductor Manufacturing Company) by compromising a third-party supplier.

Sensitive business data was exposed, and attackers demanded a staggering $70 million ransom.

Major players like Intel and AMD have also suffered firmware-related breaches, with engineering documentation and signing keys leaked on underground forums, enabling BIOS- and firmware-level rootkit attacks.

To combat these growing threats, semiconductor companies must adopt comprehensive cybersecurity strategies.

Darknet monitoring should be a core focus, enabling organizations to track mentions of sensitive company assets, stolen credentials, and exploit discussions.

Monitoring the activities of Initial Access Brokers and ransomware groups, alongside continuous threat hunting on private forums, can provide early warnings of potential compromises.

By applying proactive measures such as robust access control, supply chain security enhancements, and leveraging threat intelligence platforms like DarkOwl, semiconductor firms can safeguard intellectual property and maintain operational continuity.

As threat actors refine their tactics, the semiconductor industry must stay vigilant and prepared to counter evolving darknet-enabled cyberattacks.
