In cybersecurity, though, even AI companies worry that the bad guys will use artificial intelligence to launch more potent attacks.Little wonder, then, that computer security has become an AI hot spot. Venture capital firms are throwing money into “machine learning” startups. Incumbent cybersecurity companies are deploying artificial intelligence in their products and services. Giant tech companies like Google are adding AI defenses to protect their cloud computing data centers. For investors looking for early signs that artificial intelligence will disrupt industries, cybersecurity is clearly a top sector to watch.State-sponsored attackers, criminal cyber-gangs and ideological hackers all could employ AI. And cybersecurity experts believe criminals will use AI to develop mutating malware that changes its structure to avoid detection.
