Microsoft on Tuesday unveiled the expansion of its Sentinel Security Incidents and Event Management solution (SIEM) as a unified agentic platform with the general availability of the Sentinel data lake. In addition, the tech giant said it's also releasing a public preview of Sentinel Graph and Sentinel Model Context Protocol ( MCP ) server to turn telemetry into a security graph and allow AI agents access an organization's security context in a standardized manner. "With graph-based context, semantic access, and agentic orchestration, Sentinel gives defenders a single platform to ingest signals, correlate across domains, and empower AI agents built in Security Copilot, VS Code using GitHub Copilot, or other developer platforms," Vasu Jakkal, corporate vice president at Microsoft Security, said in a post shared with The Hacker News. Microsoft released Sentinel data lake in public preview earlier this July as a purpose-built, cloud-native tool to ingest, manage...

Today, every unpatched system, leaked password, and overlooked plugin is a doorway for attackers. Supply chains stretch deep into the code we trust, and malware hides not just in shady apps — but in job offers, hardware, and cloud services we rely on every day. Hackers don't need sophisticated exploits anymore. Sometimes, your credentials and a little social engineering are enough. This week, we trace how simple oversights turn into major breaches — and the silent threats most companies still underestimate. Let's dive in. ⚡ Threat of the Week UNC5221 Exploits New Ivanti Flaw to Drop Malware — The China-nexus cyber espionage group tracked as UNC5221 exploited a now-patched flaw in Ivanti Connect Secure, CVE-2025-22457 (CVSS score: 9.0), to deliver an in-memory dropper called TRAILBLAZE, a passive backdoor codenamed BRUSHFIRE, and the SPAWN malware suite. The vulnerability was originally patched by Ivanti on February 11, 2025, indicating that the threat actors studied the patch a...

A team of academic researchers—who previously made the headlines earlier this year for uncovering severe security issues in the 4G LTE and 5G networks —today presented a new attack called ' ReVoLTE ,' that could let remote attackers break the encryption used by VoLTE voice calls and spy on targeted phone calls. The attack doesn't exploit any flaw in the Voice over LTE (VoLTE) protocol; instead, it leverages weak implementation of the LTE mobile network by most telecommunication providers in practice, allowing an attacker to eavesdrop on the encrypted phone calls made by targeted victims. VoLTE or Voice over Long Term Evolution protocol is a standard high-speed wireless communication for mobile phones and data terminals, including Internet of things (IoT) devices and wearables, deploying 4G LTE radio access technology. The crux of the problem is that most mobile operators often use the same keystream for two subsequent calls within one radio connection to encrypt th...

The SolarWinds attack , which succeeded by utilizing the sunburst malware , shocked the cyber-security industry. This attack achieved persistence and was able to evade internal systems long enough to gain access to the source code of the victim. Because of the far-reaching SolarWinds deployments, the perpetrators were also able to infiltrate many other organizations, looking for intellectual property and other assets. Among the co-victims: US government, government contractors, Information Technology companies, and NGOs. An incredible amount of sensitive data was stolen from several customers after a trojanized version of SolarWinds' application was installed on their internal structures. Looking at the technical capabilities of the malware, as you will see, this particular attack was quite impressive. A particular file, named  SolarWinds.Orion.Core.BusinessLayer.dll  is a SolarWinds digitally signed component of the Orion software framework. The threat actors installed a...

Organizations today face relentless cyber attacks, with high-profile breaches hitting the headlines almost daily. Reflecting on a long journey in the security field, it's clear this isn't just a human problem—it's a math problem. There are simply too many threats and security tasks for any SOC to manually handle in a reasonable timeframe. Yet, there is a solution. Many refer to it as SOC 3.0—an AI-augmented environment that finally lets analysts do more with less and shifts security operations from a reactive posture to a proactive force. The transformative power of SOC 3.0 will be detailed later in this article, showcasing how artificial intelligence can dramatically reduce workload and risk, delivering world-class security operations that every CISO dreams of. However, to appreciate this leap forward, it's important to understand how the SOC evolved over time and why the steps leading up to 3.0 set the stage for a new era of security operations. A brief history of the SOC For deca...

The stealer malware known as  LummaC2  (aka Lumma Stealer) now features a new anti-sandbox technique that leverages the mathematical principle of trigonometry to evade detection and exfiltrate valuable information from infected hosts. The method is designed to "delay detonation of the sample until human mouse activity is detected," Outpost24 security researcher Alberto Marín  said  in a technical report shared with The Hacker News. Written in the C programming language, LummaC2 has been sold in underground forums since December 2022. The malware has since  received   iterative updates  that make it harder to analyze via control flow flattening and even allow it to deliver additional payloads. The current version of LummaC2 (v4.0) also requires its customers to use a  crypter  as an added concealing mechanism, not to mention prevent it from being leaked in its raw form. Another noteworthy update is the reliance on trigonometry to detect ...

It's known, drones are privileged vehicles for reconnaissance and attacks, technology has achieved level of excellence and their use is largely diffused, that's why defense companies are providing new solution to make them increasingly effective. But the incredible amount of technological components could be itself a point of weakness, last year in fact an U.S. stealthy RQ-170 Sentinel drone was captured by Iranian military near the city of Kashmar. The vehicle was used in reconnaissance mission, it took off from near Afghanistan, exactly from Kandahar airfield. In this hours government of Teheran has announced to have captured a new drone, Iran's Islamic Revolution Guards Corps (IRGC) Navy Commander Rear Admiral Ali Fadavi reported that on Dec. 5th Iranian defense has captured a Scan Eagle drone that violated the fly zone over the Persian Gulf, around Kharg Island, in southern Iran. The zone is a strategic area, the place provides a sea port for the export o...

Unpatched software is a computer code containing known security weaknesses. Unpatched vulnerabilities refer to weaknesses that allow attackers to leverage a known security bug that has not been patched by running malicious code. Software vendors write additions to the codes, known as "patches," when they come to know about these application vulnerabilities to secure these weaknesses. Adversaries often probe into your software, looking for unpatched systems and attacking them directly or indirectly. It is risky to run unpatched software. This is because attackers get the time to become aware of the  software's unpatched vulnerabilities  before a patch emerges. A  report  found that unpatched vulnerabilities are the most consistent and primary ransomware attack vectors. It was recorded that in 2021,  65  new vulnerabilities arose that were connected to ransomware. This was observed to be a twenty-nine percent growth compared to the number of vulnerabilitie...

The average website has serious vulnerabilities more than nine months of the year, according to a new report issued yesterday. According to a study issued by researchers at WhiteHat Security, the average site is exposed about 270 days of the year. "Information Leakage" has replaced Cross-Site Scripting (XSS) as the most common website vulnerability, the report says. The report examined data from more than 3,000 websites across 400 organizations that are continually tested for vulnerabilities by WhiteHat Security's Sentinel service. The study offers a look at sites' "Window of Exposure," which measures not only the vulnerabilities found in sites, but the length of time it takes those vulnerabilities to be remediated. "It's inevitable that websites will contain some faulty code -- especially in sites that are continually updated. Window of Exposure is a useful combination of the vulnerability prevalence, the time it takes to fix vulnerabilities, and...

The U.S. Environmental Protection Agency (EPA) said it's forming a new "Water Sector Cybersecurity Task Force" to devise methods to counter the threats faced by the water sector in the country. "In addition to considering the prevalent vulnerabilities of water systems to cyberattacks and the challenges experienced by some systems in adopting best practices, this Task Force in its deliberations would seek to build upon existing collaborative products," the EPA  said . In a letter sent to all U.S. Governors, EPA Administrator Michael Regan and National Security Advisor Jake Sullivan highlighted the need to secure water and wastewater systems (WWS) from cyber attacks that could disrupt access to clean and safe drinking water. At least two threat actors have been linked to intrusions targeting the nation's water systems, including those by an Iranian hacktivist group named  Cyber Av3ngers  as well as the China-linked  Volt Typhoon , which has targeted commu...

Google's one-year-old cybersecurity venture Chronicle today announced its first commercial product, called Backstory , a cloud-based enterprise-level threat analytics platform that has been designed to help companies quickly investigate incidents, pinpoint vulnerabilities and hunt for potential threats. Network infrastructures at most enterprises regularly generate enormous amounts of network data and logs on a daily basis that can be helpful to figure out exactly what happened when a security incident occurs. However, unfortunately, most companies either don't collect the right telemetry or even when they do, it's practically impossible for them to retain that telemetry for more than a week or two, making analysts blind if any security incident happens before that. Backstory solves this problem by allowing organizations to privately upload and store their petabytes of "internal security telemetry" on Google cloud platform and leverage machine learning and da...
