Mythos attack on 3rd-round PQC algorithm HAWK puts it out of commission
HAWK survived years of testing before the Mythos technique exposed a fatal cryptographic weakness.

- The HAWK algorithm withstood years of rigorous security testing without revealing critical flaws.
- A novel attack technique known as Mythos successfully uncovered deep-seated cryptographic weaknesses.
- The newly exposed vulnerabilities forced the algorithm to be pulled out of the competition entirely.
In the realm of modern cybersecurity, developing Post-Quantum Cryptography (PQC) algorithms capable of withstanding quantum computer attacks is a monumental challenge. One prominent contender, HAWK, had spent years undergoing intense scrutiny and evaluation by global cryptographic experts without any record of fatal vulnerabilities.
The landscape shifted dramatically, however, when researchers applied a newly devised attack vector named Mythos to the algorithm. Rather than confirming its robust nature, the Mythos technique successfully laid bare cryptographic weaknesses that had remained entirely hidden under the radar for years.
Uncovering flaws through innovative testing methods like Mythos highlights a crucial reality in cryptography: traditional evaluation frameworks alone are often insufficient. Proactive and aggressive attack simulations are vital for exposing edge-case vulnerabilities, ensuring that only the most resilient algorithms survive to secure future digital infrastructures.
Consequently, the gravity of this discovery proved terminal for HAWK. As a 3rd-round candidate in the broader PQC standardization initiative, the algorithm was officially sidelined and put out of commission due to its inability to guarantee security against this modern threat.
