Artificial intelligence (AI) holds tremendous promise for improving cyber defense and making the lives of security practitioners easier. It can help teams cut through alert fatigue, spot patterns faster, and bring a level of scale that human analysts alone can’t match. But realizing that potential depends on securing the systems that make it possible. Every organization experimenting with AI in security operations is, knowingly or not, expanding its attack surface. Without clear governance, strong identity controls, and visibility into how AI makes its decisions, even well-intentioned deployments can create risk faster than they reduce it. To truly benefit from AI, defenders need to approach securing it with the same rigor they apply to any other critical system. That means establishing trust in the data it learns from, accountability for the actions it takes, and oversight for the outcomes it produces. When secured correctly, AI can amplify human capability instead of replacing it t...

A new malware attributed to the Russia-linked hacking group known as COLDRIVER has undergone numerous developmental iterations since May 2025, suggesting an increased "operations tempo" from the threat actor. The findings come from Google Threat Intelligence Group (GTIG), which said the state-sponsored hacking crew has rapidly refined and retooled its malware arsenal merely five days following the publication of its LOSTKEYS malware around the same time. While it's currently not known for how long the new malware families have been under development, the tech giant's threat intelligence team said it has not observed a single instance of LOSTKEYS since disclosure. The new malware, codenamed NOROBOT, YESROBOT, and MAYBEROBOT, is "a collection of related malware families connected via a delivery chain," GTIG researcher Wesley Shields said in a Monday analysis. The latest attack waves are something of a departure from COLDRIVER's typical modus opera...

A European telecommunications organization is said to have been targeted by a threat actor that aligns with a China-nexus cyber espionage group known as Salt Typhoon . The organization, per Darktrace , was targeted in the first week of July 2025, with the attackers exploiting a Citrix NetScaler Gateway appliance to obtain initial access. Salt Typhoon, also known as Earth Estries, FamousSparrow, GhostEmperor, and UNC5807, is the name given to an advanced persistent threat actor with ties to China. Known to be active since 2019, the group gained prominence last year following its attacks on telecommunications services providers, energy networks, and government systems in the U.S. The adversary has a track record of exploiting security flaws in edge devices, maintaining deep persistence, and exfiltrating sensitive data from victims in more than 80 countries across North America, Europe, the Middle East, and Africa. In the incident observed against the European telecommunications enti...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday added five security flaws to its Known Exploited Vulnerabilities ( KEV ) Catalog, officially confirming a recently disclosed vulnerability impacting Oracle E-Business Suite (EBS) has been weaponized in real-world attacks. The security defect in question is CVE-2025-61884 (CVSS score: 7.5), which has been described as a server-side request forgery (SSRF) vulnerability in the Runtime component of Oracle Configurator that could allow attackers unauthorized access to critical data. "This vulnerability is remotely exploitable without authentication," CISA said. CVE-2025-61884 is the second flaw in Oracle EBS to be actively exploited along with CVE-2025-61882 (CVSS score: 9.8), a critical bug that could permit unauthenticated attackers to execute arbitrary code on susceptible instances. Earlier this month, Google Threat Intelligence Group (GTIG) and Mandiant revealed dozens of organizations may hav...

It’s easy to think your defenses are solid — until you realize attackers have been inside them the whole time. The latest incidents show that long-term, silent breaches are becoming the norm. The best defense now isn’t just patching fast, but watching smarter and staying alert for what you don’t expect. Here’s a quick look at this week’s top threats, new tactics, and security stories shaping the landscape. ⚡ Threat of the Week F5 Exposed to Nation-State Breach — F5 disclosed that unidentified threat actors broke into its systems and stole files containing some of BIG-IP's source code and information related to undisclosed vulnerabilities in the product. The company said it learned of the incident on August 9, 2025, although it's believed that the attackers were in its network for at least 12 months. The attackers are said to have used a malware family called BRICKSTORM, which is attributed to a China-nexus espionage group dubbed UNC5221. GreyNoise said it observed elevat...
