Unpatched zero-day vulnerabilities can be a potential gold mine for cybercriminals to take control over systems and launch a variety of attacks. In the past 24 hours, researchers have detected a zero-day vulnerability in the Oracle Solaris operating system, being used in the wild. The flaw is being exploited actively by the UNC1945 threat actor group to hack into corporate networks. It allowed the attackers to bypass authentication procedures and install a backdoor named SLAPSTICK on internet-exposed Solaris servers.
On the other hand, a unique attack method that can enable attackers to bypass firewall protection has been demonstrated by researchers. Called NAT Slipstreaming, the method involves sending the target a link to a malicious site which, in turn, allows attackers to circumvent restrictions and open any TCP/UDP port.
