"Hackers have broken into at least one organization using Windows vulnerabilities published online by a disgruntled security researcher over the last two weeks, according to a cybersecurity firm."
"BlueHammer is the only bug among the three vulnerabilities being exploited that Microsoft has patched so far. A fix for BlueHammer was rolled out earlier this week."
"All three vulnerabilities affect the Microsoft-made antivirus Windows Defender, allowing a hacker to gain high-level or administrator access to an affected Windows computer."
""I was not bluffing Microsoft and I'm doing it again," they wrote. "Huge thanks to MSRC leadership for making this possible," they added."
Hackers have exploited three Windows vulnerabilities, BlueHammer, UnDefend, and RedSun, published by a researcher named Chaotic Eclipse. BlueHammer is the only vulnerability that Microsoft has patched. The exploits allow hackers to gain high-level access to Windows computers. Chaotic Eclipse published the exploit code online, citing a conflict with Microsoft as motivation. Microsoft supports coordinated vulnerability disclosure to ensure thorough investigation of issues. The specific targets of the attacks and the identities of the hackers remain unclear.
