Three Windows Defender vulnerabilities have been disclosed, along with exploit code, and hackers are now using them in live attacks. The report points to an active security risk for Windows users and enterprise defenders, increasing the likelihood of patching and mitigation activity. Market impact is likely limited to cybersecurity-related names, but the news is negative for broader technology security sentiment.
