Incident response is much more than removing malware from an endpoint and allowing it back on the network. Understanding the 'how' is crucial. For example, if a user clicks a link and downloads a trojan horse, it's important to understand how it happened. Implementing policies to prevent such incidents is even more important. System administrators can enforce policies via GPO that require admin privileges to download software, ensuring that only authorized personnel can install new programs.In my lab environment, I have implemented these security mechanisms, although I am aware of potential workarounds that threat actors might use. If a piece of software is necessary for a job, the systems team should be informed so they can install it from a trusted source. Everyday users may not be as knowledgeable or cyber-savvy, which is a problem in itself, but I digress on that point lol.The "Lessons Learned" Phase is CRUCIAL to ensure that the chances of something like that happening again are slim to none. #cybersecurity #network #incidentresponse

    Cracked software seems like a tempting way to bypass licensing fees, but it often comes with a hidden cost: security vulnerabilities.

    🔒 1Password Vulnerability Alert for macOS Users 🚨1Password has reported a serious security vulnerability (CVE-2024-42219) affecting macOS users on versions earlier than 8.10.36. This flaw could allow attackers to steal sensitive data like passwords and credit card info. The issue stems from how 1Password for Mac handles inter-process communications, potentially enabling attackers to gain unauthorized access to vaults.To exploit this, attackers need to install malicious software on the victim's Mac, highlighting the importance of staying vigilant against social engineering tactics. With approximately 150,000 businesses relying on 1Password, the widespread impact could be significant.While there is no current evidence of exploitation, the public disclosure increases the risk. Users are urged to update to version 8.10.36 or later immediately to mitigate the vulnerability and prevent potential attacks.Best practices include updating to the latest version, being cautious of suspicious software installations, and conducting regular security reviews to enhance cyber defenses. By taking these steps, users can safeguard their sensitive information and maintain the security of their vaults. #1Password #MacSecurity #CyberAwareness #PatchIt

    When your computer is connected to any network, your software security could be compromised without certain protocols in place. Forgetting updates, software application product weakness and unresolved developer issues leave your users wide open to computer security vulnerabilities.The most common software security vulnerabilities are:>Cross-site scripting and forgery.>Download of codes without integrity checks.>Use of broken algorithms.>URL redirection to untrusted sites.>Path traversal.>Bugs.>Weak passwords.>Software that is already infected with a virus.We recommend Our Continuous Vulnerability Assessment service to Assess and monitor your environment continuously (no days off) to report on application and infrastructure changes that risk your security posture. This very powerful but inexpensive offering could be the difference between your company's security program being a Star or a Disaster.#managedsecurityservices #cybersecurity #vulnerabilitymanagement #threatintelligence
