What public money does to open-source projects

Help Net Security

Open-source software plays a crucial role in the infrastructure of many companies, with about 96 percent of codebases incorporating it. This reliance became evident with high-profile vulnerabilities like the log4j flaw in December 2021, which affected a wide range of applications, from social media platforms to gaming software. More recently, the xz utils backdoor discovered in 2024 has further emphasized the security risks associated with open-source projects. These incidents raise concerns about the stability and security of software that many organizations depend on but do not financially support. As open-source projects often rely on volunteer contributions, the need for dedicated funding and resources to maintain and secure these projects is becoming increasingly critical.

Ransom demands are down, email is the top way attackers get in

Help Net Security

A recent survey of 2,158 IT and security leaders reveals that email, particularly through phishing attacks, is the primary method for cyber attackers to gain access to networks. In many cases, employees unknowingly open malicious emails and provide their login credentials, allowing attackers to infiltrate deeper into the system. This chain of events often leads to ransomware incidents, where files become inaccessible. Notably, while ransom demands have decreased, the reliance on email as an attack vector remains significant, accounting for half of all reported incidents. This trend emphasizes the need for organizations to bolster their email security and educate employees about the risks of phishing.

Companies keep getting breached by vulnerabilities they already knew about

Help Net Security

A recent survey by Vicarius reveals a troubling trend in cybersecurity: many companies are getting breached by vulnerabilities they were already aware of. Despite advanced scanning tools that help identify weaknesses across systems, organizations struggle with the subsequent steps of fixing these vulnerabilities. The survey included responses from 300 IT and cybersecurity leaders in the U.S. and the U.K., highlighting a significant gap in the process of assigning, approving, deploying, and confirming fixes. This issue raises concerns about the effectiveness of current cybersecurity strategies and the potential risks to sensitive data. Organizations need to address these gaps to better protect themselves from breaches that could have been prevented.

GPT-Red beat human red teamers on a prompt injection test

Help Net Security

OpenAI's GPT-Red, an automated red-teaming model, has outperformed human red teamers in testing for prompt injection vulnerabilities. The model operates similarly to a human attacker, sending prompts to a GPT model and analyzing the responses to identify weaknesses. Through a process called self-play reinforcement learning, GPT-Red learns alongside various defensive models to improve its effectiveness in finding and exploiting vulnerabilities. This development raises concerns about the capabilities of AI in cybersecurity, as it can potentially identify and exploit weaknesses faster than human teams can respond. As AI continues to advance, organizations may need to enhance their defenses against such automated threats.

Finance phishing works because it sounds boringly normal

Help Net Security

Phishing attacks targeting finance departments are becoming increasingly sophisticated and effective. According to research from Cofense, attackers are crafting phishing emails that mimic legitimate business communications, making them harder to detect. These emails often bypass advanced email security tools, such as AI-based secure email gateways, because they lack the typical urgency cues that would raise alarms. This tactic poses a significant risk to organizations in the financial sector, as employees might unknowingly engage with these deceptive messages, potentially leading to data breaches or financial loss. Companies need to enhance employee training and awareness to combat these subtle phishing efforts.
