Weekly Cybersecurity Roundup: Uncovered Windows Vulnerabilities, VPN Breaches, Advanced AI Risks, Antivirus Compromises and More

where time is a luxury that cybersecurity can no longer afford, the need for proactive measures has never been more critical.

Windows 0-Day

Microsoft recently disclosed a 0-day vulnerability in its Windows Print Spooler Service known as PrintNightmare.

The vulnerability, tracked as CVE-2021-34527, allows attackers remote code execution possibilities and provides the ability to install programs, modify data, or create new accounts with full user rights.

This privilege escalation vulnerability affects Microsoft Windows 10 and possibly other Windows versions.

Despite a patch release, the quick move by attackers suggests that 0-day exploits might no longer be a reactive threat, but something companies need to proactively plan for.

VPN Exploits

Multiple vulnerabilities have been discovered in popular VPN solutions like Pulse Connect Secure and Fortinet’s VPN, which hackers have utilized to infiltrate companies ‘behind the security perimeter.’ Bad actors leverage these vulnerabilities to gain initial access to a victim’s network and then move laterally to further exploit more sensitive information.

The CVE-2021-22893 vulnerability in Pulse Connect Secure, for instance, is particularly alarming due to its severity rating of 10, the highest possible on the CVSS scale.

Weaponized AI

As AI technologies progress, so do the tactics of cybercriminals.

Deepfake technology, for instance, is now being used to bypass facial recognition systems, and AI-powered phishing tools make it easier to trick users into divulging sensitive information.

Cybercriminals are exploiting these novel AI capabilities to devise advanced attacks, making the cybersecurity landscape even more challenging.

Hijacked Antivirus

In a surprising twist of events, cybercriminals are now hijacking trusted security tools to deliver malware.

Solarmarker, a well-known information-stealing malware, is being hidden in popular antivirus software, affecting both individuals and businesses.

This latest development is a reminder that no software, even those designed to protect us, is immune to cyber threats.

Conclusion

From unpatched Windows vulnerabilities to weaponized Artificial Intelligence, these incidents shed light on the increasingly precarious digital landscape.

With threat actors becoming more sophisticated, it is imperative for both businesses and individuals to take proactive measures, stay informed, and make cybersecurity a priority.
