Artificial intelligence is rapidly becoming the most powerful weapon in the fight against software vulnerabilities, but the cybercrime front is not standing still. Two news stories this month perfectly illustrate the duality of modern cybersecurity: on one side, the triumph of defensive AI with Mozilla's Mythos system; on the other, the latest incursion by the ShinyHunters group targeting the educational platform Instructure. Together, these events redefine priorities for companies and institutions.
Mozilla Mythos: bug hunting becomes nearly perfect
The Firefox development team has announced an unprecedented result: the artificial intelligence-assisted vulnerability discovery system called Mythos has identified 271 security flaws with an almost zero false positive rate. According to Mozilla, the company has now "completely bought in" to AI for bug hunting, marking a sea change in code auditing methodologies. Mythos's ability to accurately distinguish between real vulnerabilities and false alarms represents a qualitative leap over traditional tools, which often overwhelm development teams with useless alerts. This means engineers can focus their energies on concrete threats, speeding up patching timelines and reducing the risk of exploits. The success of Mythos comes at a time when software security is under the spotlight, also due to cases like the Musk versus OpenAI lawsuit, which has questioned the safety of AI models.

ShinyHunters strikes again: schools in the crosshairs
While Mozilla celebrates the progress of defensive AI, the criminal group ShinyHunters has demonstrated that human attacks remain a devastating threat. According to sources close to the investigation, the group has once again breached the systems of Instructure, the company behind the popular learning platform Canvas. The hackers defaced the login pages of several client schools, posting an extortion message. This attack on the educational supply chain highlights the vulnerability of school digital infrastructures, which are often less protected than corporate ones. ShinyHunters's modus operandi, combining exploits on known software with social engineering techniques, echoes what happened in the recent Daemon Tools alert, where a supply chain attack compromised the popular virtual disk software. The difference is that here the target is sensitive data of students and teachers, with potential consequences on privacy and the academic future of victims.
An increasingly polarized cybersecurity ecosystem
Reading the two news items together paints a complex picture. On one hand, tools like Mythos show that AI can dramatically raise proactive security standards. On the other hand, groups like ShinyHunters exploit the slowness of organizations to update defenses, striking weak points in the supply chain. Mozilla itself emphasized that Mythos is not a magic wand: its effectiveness depends on the quality of training data and human collaboration. Meanwhile, cybercrime continues to evolve, as analyzed in the article on Cybercrime 2026 and the rise of AI defense. For industry professionals, the lesson is clear: they must invest both in cutting-edge AI technologies and in human security processes, without neglecting end-user training. Only by combining intelligent machines and human vigilance can we hope to keep pace with increasingly sophisticated threats.
