    The Microsoft Windows 10 operating system integrates an antivirus: it is Windows Defender and it is considered more than enough to protect most users' work and browsing. But he has a problem, even a big one: a bug recently discovered that it could allow a hacker to remotely infect your computer.

    It could and perhaps already has, because cybersecurity researchers believe that the vulnerability, coded as CVE-2021-1647, has been exploited in the past three months by hackers as part of the massive attack on SolarWinds. That is the attack, allegedly carried out by hackers linked to the Russian government, which led to the sensational theft of data from most departments of the Trump administration. Last month, then, Microsoft said that Russian-sponsored hackers have indeed compromised its internal network and leveraged other Microsoft products to conduct further attacks. This bug in Windows Defender appears to be one used by cybercriminals.
