Staying private online and avoiding being tracked is the best option to ensure our security while browsing and using apps.

Recent years have demonstrated that Windows users are not the only ones who should be concerned about malware. Linux is becoming an increasingly popular target among malware operators due to the growing popularity of the open-source OS and the high-value devices it powers worldwide. Security researchers from AT&T Alien Labs are now warning that “cyber gangs have started infecting Linux machines via a fileless malware installation technique that until recently was more commonly used against Windows-based systems”.

Nmap Firewall Evasion Techniques

The primary goal of firewall penetration testing is to prevent unauthorized internet access to your organization's internal network, or check to make sure your security policy is doing what you think it's doing. In order to successfully test your organization's firewall, you must think like the adversary. Collecting intelligence on the network, such as operating system and firewall type, are important to know in order to proceed with the penetration test.

Qualys Research Team Warns of Significant polkit Vulnerability Affecting All Linux Users

data:image/svg+xml,%3Csvg%20xmlns=%22https://www.w3.org/2000/svg%22%20viewBox=%220%200%20100%20100%22%3E%3C/svg%3E

The Qualys Research Team reached out to LinuxSecurity after discovering a memory corruption vulnerability in polkit’s pkexec. Pkexec is a SUID-root program that is installed by default on every major Linux distribution of the open-source operating system. This vulnerability is easily exploited and gives hackers the opportunity to gain full root privileges on a vulnerable host. Much like the Log4j vulnerability, the severity of this flaw is high and it is imperative that vulnerabilities are reported in a timely fashion. Experts also expressed that due to the simple possibility for exploitation the vulnerability needs to be patched and mitigated immediately.
