Hyper-Volumetric DDoS Attacks Reach Record 7.3 Tbps, Targeting Key Global Sectors

Jul 15, 2025 Botnet / Network Security
Cloudflare on Tuesday said it mitigated 7.3 million distributed denial-of-service (DDoS) attacks in the second quarter of 2025, a significant drop from 20.5 million DDoS attacks it fended off the previous quarter. "Overall, in Q2 2025, hyper-volumetric DDoS attacks skyrocketed," Omer Yoachimik and Jorge Pacheco said . "Cloudflare blocked over 6,500 hyper-volumetric DDoS attacks, an average of 71 per day." In Q1 2025, the company said an 18-day sustained campaign against its own and other critical infrastructure protected by Cloudflare was responsible for 13.5 million of the attacks observed during the time period. Cumulatively, Cloudflare has blocked nearly 28 million DDoS attacks, surpassing the number of attacks it mitigated in all of 2024. The notable of the attacks in Q2 2025 is a staggering DDoS attack that peaked at 7.3 terabits per second (Tbps) and 4.8 billion packets per second (Bpps) within a span of 45 seconds. Big traffic spikes like these make he...
Newly Emerged GLOBAL GROUP RaaS Expands Operations with AI-Driven Negotiation Tools

Newly Emerged GLOBAL GROUP RaaS Expands Operations with AI-Driven Negotiation Tools

Jul 15, 2025 Cybercrime / Ransomware
Cybersecurity researchers have shed light on a new ransomware-as-a-service (RaaS) operation called GLOBAL GROUP that has targeted a wide range of sectors in Australia, Brazil, Europe, and the United States since its emergence in early June 2025. GLOBAL GROUP was "promoted on the Ramp4u forum by the threat actor known as '$$$,'" EclecticIQ researcher Arda Büyükkaya said . "The same actor controls the BlackLock RaaS and previously managed Mamona ransomware operations." It's believed that GLOBAL GROUP is a rebranding of BlackLock after the latter's data leak site was defaced by the DragonForce ransomware cartel back in March. It's worth mentioning that BlackLock in itself is a rebrand of another RaaS scheme known as Eldorado. The financially motivated group has been found to lean heavily on initial access brokers (IABs) to deploy the ransomware by weaponizing access to vulnerable edge appliances from Cisco, Fortinet, and Palo Alto Networks. Al...
State-Backed HazyBeacon Malware Uses AWS Lambda to Steal Data from SE Asian Governments

State-Backed HazyBeacon Malware Uses AWS Lambda to Steal Data from SE Asian Governments

Jul 15, 2025 Cyber Espionage / Threat Intelligence
Governmental organizations in Southeast Asia are the target of a new campaign that aims to collect sensitive information by means of a previously undocumented Windows backdoor dubbed HazyBeacon . The activity is being tracked by Palo Alto Networks Unit 42 under the moniker CL-STA-1020 , where "CL" stands for "cluster" and "STA" refers to "state-backed motivation." "The threat actors behind this cluster of activity have been collecting sensitive information from government agencies, including information about recent tariffs and trade disputes," security researcher Lior Rochberger said in a Monday analysis. Southeast Asia has increasingly become a focal point for cyber espionage due to its role in sensitive trade negotiations, military modernization, and strategic alignment in the U.S.–China power dynamic. Targeting government agencies in this region can provide valuable intelligence on foreign policy direction, infrastructure planni...

Securing Agentic AI: How to Protect the Invisible Identity Access

Securing Agentic AI: How to Protect the Invisible Identity Access

Jul 15, 2025 Automation / Risk Management
AI agents promise to automate everything from financial reconciliations to incident response. Yet every time an AI agent spins up a workflow, it has to authenticate somewhere; often with a high-privilege API key, OAuth token, or service account that defenders can't easily see. These "invisible" non-human identities (NHIs) now outnumber human accounts in most cloud environments, and they have become one of the ripest targets for attackers. Astrix's Field CTO Jonathan Sander put it bluntly in a recent Hacker News webinar : "One dangerous habit we've had for a long time is trusting application logic to act as the guardrails. That doesn't work when your AI agent is powered by LLMs that don't stop and think when they're about to do something wrong. They just do it." Why AI Agents Redefine Identity Risk Autonomy changes everything: An AI agent can chain multiple API calls and modify data without a human in the loop. If the underlying credential is exposed or overprivileged, each addit...
AsyncRAT's Open-Source Code Sparks Surge in Dangerous Malware Variants Across the Globe

AsyncRAT's Open-Source Code Sparks Surge in Dangerous Malware Variants Across the Globe

Jul 15, 2025 Malware / Cybercrime
Cybersecurity researchers have charted the evolution of a widely used remote access trojan called AsyncRAT , which was first released on GitHub in January 2019 and has since served as the foundation for several other variants. "AsyncRAT has cemented its place as a cornerstone of modern malware and as a pervasive threat that has evolved into a sprawling network of forks and variants," ESET researcher Nikola Knežević said in a report shared with The Hacker News. "While its capabilities are not that impressive on their own, it is the open-source nature of AsyncRAT that has truly amplified its impact. Its plug-in-based architecture and ease of modification have sparked the proliferation of many forks, pushing the boundaries even further" While AsyncRAT's evolution highlights its technical adaptability, its real-world impact stems from how it's deployed in opportunistic phishing campaigns and bundled with loaders like GuLoader or SmokeLoader. These delivery metho...
Between Buzz and Reality: The CTEM Conversation We All Need

Between Buzz and Reality: The CTEM Conversation We All Need

Jun 24, 2025Threat Exposure Management
I had the honor of hosting the first episode of the Xposure Podcast live from Xposure Summit 2025. And I couldn't have asked for a better kickoff panel: three cybersecurity leaders who don't just talk security, they live it. Let me introduce them. Alex Delay , CISO at IDB Bank, knows what it means to defend a highly regulated environment. Ben Mead , Director of Cybersecurity at Avidity Biosciences, brings a forward-thinking security perspective that reflects the innovation behind Avidity's targeted RNA therapeutics. Last but not least, Michael Francess , Director of Cybersecurity Advanced Threat at Wyndham Hotels and Resorts, leads the charge in protecting the franchise. Each brought a unique vantage point to a common challenge: applying Continuous Threat Exposure Management (CTEM) to complex production environments. Gartner made waves in 2023 with a bold prediction: organizations that prioritize CTEM will be three times less likely to be breached by 2026. But here's the kicker -...
North Korean Hackers Flood npm Registry with XORIndex Malware in Ongoing Attack Campaign

North Korean Hackers Flood npm Registry with XORIndex Malware in Ongoing Attack Campaign

Jul 15, 2025 Malware / Web Security
The North Korean threat actors linked to the Contagious Interview campaign have been observed publishing another set of 67 malicious packages to the npm registry, underscoring ongoing attempts to poison the open-source ecosystem via software supply chain attacks. The packages, per Socket, have attracted more than 17,000 downloads, and incorporate a previously undocumented version of a malware loader codenamed XORIndex . The activity is an expansion of an attack wave spotted last month that involved the distribution of 35 npm packages that deployed another loader referred to as HexEval. "The Contagious Interview operation continues to follow a whack-a-mole dynamic, where defenders detect and report malicious packages, and North Korean threat actors quickly respond by uploading new variants using the same, similar, or slightly evolved playbooks," Socket researcher Kirill Boychenko said . Contagious Interview is the name assigned to a long-running campaign that seeks to en...
The Unusual Suspect: Git Repos

The Unusual Suspect: Git Repos

Jul 14, 2025 Secrets Management / SaaS Security
While phishing and ransomware dominate headlines, another critical risk quietly persists across most enterprises: exposed Git repositories leaking sensitive data. A risk that silently creates shadow access into core systems Git is the backbone of modern software development, hosting millions of repositories and serving thousands of organizations worldwide. Yet, amid the daily hustle of shipping code, developers may inadvertently leave behind API keys, tokens, or passwords in configuration files and code files, effectively handing attackers the keys to the kingdom. This isn't just about poor hygiene; it's a systemic and growing supply chain risk. As cyber threats become more sophisticated, so do compliance requirements. Security frameworks like NIS2, SOC2, and ISO 27001 now demand proof that software delivery pipelines are hardened and third-party risk is controlled. The message is clear: securing your Git repositories is no longer optional, it's essential. Below, we look at the ris...
New PHP-Based Interlock RAT Variant Uses FileFix Delivery Mechanism to Target Multiple Industries

New PHP-Based Interlock RAT Variant Uses FileFix Delivery Mechanism to Target Multiple Industries

Jul 14, 2025 Malware / Web Security
Threat actors behind the Interlock ransomware group have unleashed a new PHP variant of its bespoke remote access trojan (RAT) as part of a widespread campaign using a variant of ClickFix called FileFix. "Since May 2025, activity related to the Interlock RAT has been observed in connection with the LandUpdate808 (aka KongTuke) web-inject threat clusters," The DFIR Report said in a technical analysis published today in collaboration with Proofpoint. "The campaign begins with compromised websites injected with a single-line script hidden in the page's HTML, often unbeknownst to site owners or visitors." The JavaScript code acts as a traffic distribution system (TDS), using IP filtering techniques to redirect users to fake CAPTCHA verification pages that leverage ClickFix to entice them into running a PowerShell script that leads to the deployment of NodeSnake (aka Interlock RAT). The use of NodeSnake by Interlock was previously documented by Quorum Cyber...

eSIM Vulnerability in Kigen's eUICC Cards Exposes Billions of IoT Devices to Malicious Attacks

Jul 14, 2025 Mobile Security / Vulnerability
Cybersecurity researchers have discovered a new hacking technique that exploits weaknesses in the eSIM technology used in modern smartphones, exposing users to severe risks. The issues impact the Kigen eUICC card. According to the Irish company's website, more than two billion SIMs in IoT devices have been enabled as of December 2020. The findings come from Security Explorations, a research lab of AG Security Research company. Kigen awarded the company a $30,000 bounty for their report. An eSIM, or embedded SIM, is a digital SIM card that's embedded directly into a device as software installed onto an Embedded Universal Integrated Circuit Card (eUICC) chip. eSIMs allow users to activate a cellular plan from a carrier without the need for a physical SIM card. eUICC software offers the ability to change operator profiles, remote provisioning, and management of SIM profiles. "The eUICC card makes it possible to install the so-called eSIM profiles into the target chi...
GPUHammer: New RowHammer Attack Variant Degrades AI Models on NVIDIA GPUs

GPUHammer: New RowHammer Attack Variant Degrades AI Models on NVIDIA GPUs

Jul 12, 2025 AI Security / Vulnerability
NVIDIA is urging customers to enable System-level Error Correction Codes (ECC) as a defense against a variant of a RowHammer attack demonstrated against its graphics processing units (GPUs). "Risk of successful exploitation from RowHammer attacks varies based on DRAM device, platform, design specification, and system settings," the GPU maker said in an advisory released this week. Dubbed GPUHammer , the attacks mark the first-ever RowHammer exploit demonstrated against NVIDIA's GPUs (e.g., NVIDIA A6000 GPU with GDDR6 Memory), causing malicious GPU users to tamper with other users' data by triggering bit flips in GPU memory. The most concerning consequence of this behavior, University of Toronto researchers found, is the degradation of an artificial intelligence (AI) model's accuracy from 80% to less than 1%. RowHammer is to modern DRAMs just like how Spectre and Meltdown are to contemporary CPUs. While both are hardware-level security vulnerabilities, Row...
