Repo_GPGcheck ensures linux verifies the authenticity of software packages downloaded from repositories, reinforcing overall system security and safeguarding against unauthorized software sources. A repository in Linux is a storage location where software packages are managed and organized. When installing or updating software, Redhat based Linux systems pull the required packages from these repositories using the YUM (Yellowdog Updater, Modified) package manager.

It’s almost impossible to use the internet without setting up a password, they are the heart of managing our accounts online. We all know the importance of preventing access to our accounts. Unfortunately, passwords are always at risk from hackers trying to access our accounts. Even if you have the strongest password available, with one accidental click on a phishing email or spoofed website, we could accidentally give cybercriminals access to our accounts or sell our accounts on the dark web.

As 2024 draws to a close, the cybersecurity landscape continues to evolve, marked by both familiar adversaries and emerging threats with newer technologies and improved tactics. Rather than merely cataloguing breaches, we look into the anatomy of significant cyber attacks, associated vulnerabilities that led to such events, and relevant controls. We’ve chronicled key developments month by month, offering a comprehensive view of the cyber attacks of 2024 narrative that would help you learn lessons.

Let’s catch up on the more interesting vulnerability disclosures and cyber security news gathered from articles across the web this week. This is what we have been reading about on our coffee break! Stand-by for a whole lot more spam and phishing emails. It never ends does it?

As organizations continue to embrace digital transformation, their infrastructure increasingly spans cloud environments, third-party integrations, and remote work setups. This shift enhances efficiency and productivity—but also broadens the digital attack surface, creating new points of exposure to the public internet.

As developers increasingly adopt chain-based and agentic LLM application architectures, the threat of critical sensitive data exposures grows. LLMs are often highly privileged within their applications and related infrastructure, with access to critical data and resources, making them an alluring target for exploitation at the client side by attackers. In particular, LLM applications can be compromised to expose sensitive data via prompt injection attacks.

Hacktivism – the practice of carrying out cyberattacks to advance political or social goals – is not new. Hacktivist attacks go as far back as the 1980s. Yet today’s hacktivists often look and operate in ways that are markedly different from their predecessors. They’ve embraced new techniques, they often have more resources at their disposal and they can prove more challenging to stop.

The National Institute of Standards and Technology (NIST) has released version 2.0 of its Cyber security Framework (CSF), significantly elevating cyber security guidelines. This update brings in major changes that will affect several actors like Chief Information Security Officers (CISOs), Managed Security Service Providers (MSSPs), and individual users, among others.
