While typically known as a household adhesive, "C" or Cyanoacrylate (CA) glue—specifically the high-viscosity "super glue" variants—has transitioned into a niche but effective tool in hardware-level antimalware and physical security. Its application focuses on hardware "hardening" to prevent unauthorized access, tampering, or the introduction of malicious peripherals. Physical Port Sealing
(e.g., procedural "how-to" vs. theoretical security analysis) C Super Glue For Antimalware Applications
Advanced applications involve mixing CA glue with unique identifiers like glitter or specific chemical tracers. If an attacker attempts to dissolve the glue to reach the hardware, the unique pattern is destroyed. This ensures that any attempt to introduce hardware-based malware or bypass Secure Boot via physical probes is immediately detectable during routine audits.

Super glue is also used to secure internal components against "Evil Maid" attacks, where a malicious actor gains brief physical access to a machine to install hardware implants. By applying CA glue to the seams of a device’s chassis or over sensitive chips and connectors (such as the SPI flash containing the BIOS/UEFI), security teams create a "tamper-evident" seal.
In supply chain security, CA glue can be used to "picket" critical hardware components during transit. By bonding heat sinks or shields to the PCB using industrial-grade cyanoacrylate, manufacturers make it significantly harder for intermediaries to desolder original components and replace them with malicious clones or "shanzhai" hardware containing backdoors.
