Windows, one of the most popular operating systems used by more than 75% of desktop users, is one of the top products being targeted by cyberattacks. According to recently disclosed statistics, Windows has been targeted by more than 80% of malware detected.
Malware-based Attacks
Two updated versions of LodaRAT were discovered targeting Bangladesh Android and Windows users. The attack vector used in these attacks was spam email with links to malicious applications or documents. LVast month, even after the takedown attempt of TrickBot, it came back with a newer version. This version was using a mechanism of Windows Task Scheduler as the way to reload the malware.
The FBI has already warned about using Windows 7, which reached end-of-life on January 14, 2020. A year ago, the agency had warned US companies about the same issue.
Various Vulnerabilities
Besides direct attacks by malware, Windows users face threats of exploitation of vulnerabilities in Windows. A vulnerability CVE-2021-1732 was being actively exploited that allowed a logged-on user to execute code of their choosing with higher privileges by running a specially crafted application.
A few weeks ago, Google engineers fixed a serious RCE vulnerability (CVE-2021-3115)that impacts Windows users. Last month, it was discovered that Windows 7 is exposed to blind TCP/IP hijacking attacks. This attack is possible by exploiting a vulnerability reported by a researcher to Microsoft eight years ago.
Microsoft advised updating systems to address the critical Zerologon flaw (tracked as CVE-2020-1472). This vulnerability allows an attack against Microsoft Active Directory domain controllers.
Conclusion
Cybercriminals are actively taking advantage of weaknesses in Windows and deploying malware for nefarious purposes. Thus, experts suggest always updating the OS with the latest update, using up-to-date anti-malware, and staying away from opening emails that come from unknown sources.
