2 Stories About Zero-day Vulnerabilities Exemplify Need of Update Program

These 2 Vulnerabilities on Zero-day vulnerabilities have possibility of causing much mayhem unless you have cybersecurity program in place to deal with updates or patches as quick as possible and other Intrusion Detection as well as anti-virus and more.

Hacker News has the stories:   RomCom Exploits Zero-day 

The Russia-aligned threat actor known as RomCom has been linked to the zero-day exploitation of two security flaws, one in Mozilla Firefox and the other in Microsoft Windows, as part of attacks designed to deliver the eponymous backdoor on victim systems.

“In a successful attack, if a victim browses a web page containing the exploit, an adversary can run arbitrary code – without any user interaction required (zero click) – which in this case led to the installation of RomCom’s backdoor on the victim’s computer,” ESET said in a report shared with The Hacker News.

also the following story: Apple releases urgent updates

Apple has released security updates for iOS, iPadOS, macOS, visionOS, and its Safari web browser to address two zero-day flaws that have come under active exploitation in the wild.

The flaws are listed below –

  • CVE-2024-44308 (CVSS score: 8.8) – A vulnerability in JavaScriptCore that could lead to arbitrary code execution when processing malicious web content
  • CVE-2024-44309 (CVSS score: 6.1) – A cookie management vulnerability in WebKit that could lead to a cross-site scripting (XSS) attack when processing malicious web content

The iPhone maker said it addressed CVE-2024-44308 and CVE-2024-44309 with improved checks and improved state management, respectively.

What do I mean by having a system? well the usual – Security Policy that includes all of the essentials (which means you are doing all of these things).

Here is a question on one of my favorite AI instances (gab.ai)

“create a security policy that would give the best defense for zero-day attacks”  as placed on 11/27/24

Here is a security policy to provide the best defense against zero-day attacks:

  1. Keep all systems and software up-to-date with the latest security patches. Patch management should be a top priority.
  2. Use an intrusion prevention system (IPS) to monitor network traffic for signs of malicious activity. Configure it to block suspicious traffic by default.
  3. Deploy advanced endpoint protection on all devices, using techniques like machine learning to detect anomalous behavior that could indicate an exploit.
  4. Segment the network to limit lateral movement if an attacker gains a foothold. Use firewalls, access control lists, and virtual LANs.
  5. Implement application whitelisting to prevent unauthorized software from running. Only allow approved, trusted applications.
  6. Use threat intelligence feeds to stay informed about the latest vulnerabilities and exploits. Prioritize defense against the threats most likely to target your organization.
  7. Conduct regular penetration testing and red team exercises to identify weaknesses and test defenses. Aim to simulate real-world zero-day attacks.
  8. Provide security awareness training to employees to help them identify and report phishing attempts and social engineering.
  9. Limit administrative privileges and use the principle of least privilege. Require multifactor authentication for privileged access.
  10. Have an incident response plan ready to quickly contain and remediate attacks. Practice the IR plan regularly.

The key is to use multiple complementary security controls to provide defense-in-depth. No single measure can completely prevent zero-days, but a strong security posture makes it much harder for attackers to succeed. Always assume compromise and prepare to detect and respond rapidly.

Why is it important to create a security policy? To communicate to your employees that what is necessary is to defend against attacks that may not have defenses except our configurations which would lessen the chance even on a zero-day attack!

What is a zero-day attack? it is a vulnerability that does not have a patch/update yet, and thus the attacker can do what they want (if you allow it).
