Xiaoli Zhou of the School of Information Engineering at Sichuan Top IT Vocational Institute in Chengdu, China, conducted a study on integrating data augmentation and ensemble learning methods to improve the accuracy of Intrusion Detection Systems (IDS). Zhou focused on a Wasserstein Generative Adversarial Network with Gradient Penalty (WGAN-GP), an advanced version of the standard Machine Learning (ML) model capable of creating realistic data through a competition between two neural networks.

With a nod to Charles Dickens, this Cyber Scene will take us to the tale of two grounded US cities—Washington DC and New York City, even as debates, be they financial or foreign affairs, are fully in best or possibly worst ethereal times.

According to Zimperium's "2024 zLabs Global Mobile Threat Report," 82 percent of all phishing sites now target mobile devices. The report also shows that 76 percent of these sites use HTTPS, leading users to believe they are secure. Healthcare remains the most vulnerable industry, with 39 percent of mobile threats coming from phishing attacks. In order to gain access to enterprise systems, cybercriminals are increasingly applying mobile-first strategies involving the exploitation of weak mobile endpoints, smaller screens, and limited security indicators.

The US Cybersecurity and Infrastructure Security Agency (CISA) warns of threat actors targeting Internet-exposed industrial devices with "unsophisticated" methods such as brute-force attacks and using default credentials to breach critical infrastructure networks. According to CISA, these attacks on critical infrastructure Operation Technology (OT) and Industrial Control System (ICS) devices have affected Water and Wastewater Systems (WWS). This article continues to discuss CISA's warning regarding threat actors exploiting OT/ICS using unsophisticated techniques.

HiddenLayer warns that Google's Artificial Intelligence (AI) assistant Gemini faces indirect prompt injection flaws that could lead to phishing and chatbot takeover attacks. Indirect injections involve delivering the prompt injection via channels such as documents, emails, and other assets accessed by the Large Language Model (LLM), with the goal of taking over the model.

Following the discovery that thousands of US Congress staffers could be vulnerable to account hijacking and phishing, security experts have repeatedly warned against using work email addresses to sign up for third-party sites. The secure mail provider Proton collaborated with Constella Intelligence to search the dark web for over 16,000 publicly available email addresses associated with congressional staff. About 3,191 employees' emails were leaked to the dark web following third-party data breaches, with 1,848 listed together with plaintext passwords.

According to the Cybersecurity and Infrastructure Security Agency (CISA), a critical authentication bypass vulnerability in Ivanti Virtual Traffic Manager (vTM) has now been exploited by threat actors in the wild.  CISA added the bug to its long list of Known Exploited Vulnerabilities (KEV) on September 24, with federal agencies given until October 15 to patch it.  However, Ivanti has yet to update its security advisory to reflect the new information.

The US House Homeland Security Committee Republicans have recently unveiled a new bill aimed at addressing the growing cyber threats posed by state-sponsored Chinese actors targeting US critical infrastructure.  The legislation established an interagency task force led by the Cybersecurity and Infrastructure Security Agency (CISA) and the FBI.  The task force will focus on countering malicious cyber activity from the Chinese Communist Party (CCP), including advanced persistent threats (APTs) like Volt Typhoon.
