From the January 14, 2020, Windows 7 reached end of its life cycle and you no longer receive security updates to fix vulnerabilities. To this we must add that there are many programs that no longer work with Windows 7, but it seems that there are many users who have no intention of updating; even though you can free upgrade from Windows 7 to Windows 10.
Using Windows 7 is opening the door for hackers
Therefore, the FBI is alerting companies in the United States of the dangers at the network level that can pose keep using Windows 7 Currently, they claim that they have detected cybercriminals attacking network infrastructures, taking advantage of the fact that an operating system is no longer supported. Thus, they state that “continuing to use Windows 7 in a company can allow a hacker to take control of that company, and the problem will become increasingly serious because the system will become more vulnerable over time.”
The best solution, according to the FBI, is clear: upgrade to an operating system yes you have support for security updates, as is the case with Windows 10, or even Windows 8, which is still supported. Many companies continue to delay updating because updating the operating system can cause incompatibility problems with the programs they use, in addition to a possible increase in cost if they have to change computers. That cost, however, is a trifle compared to what it would mean to suffer a hack.
If you don’t update at least have a good antivirus and firewall
In the event that you cannot yet upgrade to a newer operating system, the FBI recommends using good antivirus, spam filters and firewalls, in addition to isolating Windows 7 computers from the network, using two-step authentication, and blocking all access to remote desktop control.
At the moment, although almost 7 months have passed since the end of Windows 7 support, it has not yet been the case that there is a great vulnerability that endangers the operating system, although this could arise at any time as it happened in 2019 with BlueKeep or in 2017 with WannaCry and ETERNALBLUE, which even required releasing a special patch for Windows XP three years after the end of update support. Back then, 98% of WannaCry infected computers used Windows 7.
