If this had been a security drill, someone would've said it went too far. But it wasn't a drill—it was real. The access? Everything looked normal. The tools? Easy to find. The detection? Came too late. This is how attacks happen now—quiet, convincing, and fast. Defenders aren't just chasing hackers anymore—they're struggling to trust what their systems are telling them. The problem isn't too few alerts. It's too many, with no clear meaning. One thing is clear: if your defense still waits for obvious signs, you're not protecting anything. You're just watching it happen. This recap highlights the moments that mattered—and why they're worth your attention. ⚡ Threat of the Week APT41 Exploits Google Calendar for Command-and-Control — The Chinese state-sponsored threat actor known as APT41 deployed a malware called TOUGHPROGRESS that uses Google Calendar for command-and-control (C2). Google said it observed the spear-phishing attacks in October 2024 and that the malware was hosted on...

Two information disclosure flaws have been identified in apport and systemd-coredump , the core dump handlers in Ubuntu, Red Hat Enterprise Linux, and Fedora, according to the Qualys Threat Research Unit (TRU). Tracked as CVE-2025-5054 and CVE-2025-4598 , both vulnerabilities are race condition bugs that could enable a local attacker to obtain access to access sensitive information. Tools like Apport and systemd-coredump are designed to handle crash reporting and core dumps in Linux systems. "These race conditions allow a local attacker to exploit a SUID program and gain read access to the resulting core dump," Saeed Abbasi, manager of product at Qualys TRU, said . A brief description of the two flaws is below - CVE-2025-5054 (CVSS score: 4.7) - A race condition in Canonical apport package up to and including 2.32.0 that allows a local attacker to leak sensitive information via PID-reuse by leveraging namespaces CVE-2025-4598 (CVSS score: 4.7) - A race condition i...

ConnectWise, the developer of remote access and support software ScreenConnect, has disclosed that it was the victim of a cyber attack that it said was likely perpetrated by a nation-state threat actor. "ConnectWise recently learned of suspicious activity within our environment that we believe was tied to a sophisticated nation-state actor, which affected a very small number of ScreenConnect customers," the company said in a brief advisory on May 28, 2025. The company said it has engaged the services of Google Mandiant to conduct a forensic probe into the incident and that it has notified all affected customers. The incident was first reported by CRN. However, it did not reveal the exact number of customers who were impacted by the hack, when it happened, or the identity of the threat actor behind it. It's worth noting that the company, in late April 2025, patched CVE-2025-3935 (CVSS score: 8.1), a high-severity vulnerability in ScreenConnect versions 25.2.3 and ea...

Detecting leaked credentials is only half the battle. The real challenge—and often the neglected half of the equation—is what happens after detection. New research from GitGuardian's State of Secrets Sprawl 2025 report reveals a disturbing trend: the vast majority of exposed company secrets discovered in public repositories remain valid for years after detection, creating an expanding attack surface that many organizations are failing to address. According to GitGuardian's analysis of exposed secrets across public GitHub repositories, an alarming percentage of credentials detected as far back as 2022 remain valid today: "Detecting a leaked secret is just the first step," says GitGuardian's research team. "The true challenge lies in swift remediation." Why Exposed Secrets Remain Valid This persistent validity suggests two troubling possibilities: either organizations are unaware their credentials have been exposed (a security visibility problem),...

An Iranian national has pleaded guilty in the U.S. over his involvement in an international ransomware and extortion scheme involving the Robbinhood ransomware. Sina Gholinejad (aka Sina Ghaaf), 37, and his co-conspirators are said to have breached the computer networks of various organizations in the United States and encrypted files with Robbinhood ransomware to demand Bitcoin ransom payments. Gholinejad, who was arrested in North Carolina in early January, pleaded guilty to one count of computer fraud and abuse and one count of conspiracy to commit wire fraud. He faces a maximum penalty of 30 years in prison. He is scheduled for sentencing in August 2025. "These cyber attacks caused significant disruptions and tens of millions in losses, including to the City of Greenville, North Carolina, and the City of Baltimore, Maryland," the U.S. Department of Justice (DoJ) said . "Baltimore lost more than $19 million from the damage caused to their computer networks and t...

The Czech Republic on Wednesday formally accused a threat actor associated with the People's Republic of China (PRC) of targeting its Ministry of Foreign Affairs. In a public statement, the government said it identified China as the culprit behind a malicious campaign targeting one of the unclassified networks of the Czech Ministry of Foreign Affairs. The extent of the breach is presently not known. "The malicious activity [...] lasted from 2022 and affected an institution designated as Czech critical infrastructure," it added . The attack has been attributed to a state-sponsored threat actor tracked as APT31 , which also overlaps with threat clusters known as Altaire, Bronze Vinewood, Judgement Panda, PerplexedGoblin, RedBravo, Red Keres, and Violet Typhoon (formerly Zirconium). The hacking group, publicly associated with the Ministry of State Security (MSS) and the Hubei State Security Department, is assessed to be active since at least 2010, per the U.S. Departme...

The U.S. Federal Bureau of Investigation (FBI) has warned of social engineering attacks mounted by a criminal extortion actor known as Luna Moth targeting law firms over the past two years. The campaign leverages "information technology (IT) themed social engineering calls, and callback phishing emails, to gain remote access to systems or devices and steal sensitive data to extort the victims," the FBI said in an advisory. Luna Moth, also called Chatty Spider, Silent Ransom Group (SRG), Storm-0252, and UNC3753, is known to be active since at least 2022 , primarily employing a tactic called callback phishing or telephone-oriented attack delivery (TOAD) to trick unsuspecting users into calling phone numbers listed in benign-looking phishing emails related to invoices and subscription payments. It's worth mentioning here that Luna Moth refers to the same hacking crew that previously carried out BazarCall (aka BazaCall) campaigns to deploy ransomware like Conti . The ...

Cyber threats don't show up one at a time anymore. They're layered, planned, and often stay hidden until it's too late. For cybersecurity teams, the key isn't just reacting to alerts—it's spotting early signs of trouble before they become real threats. This update is designed to deliver clear, accurate insights based on real patterns and changes we can verify. With today's complex systems, we need focused analysis—not noise. What you'll see here isn't just a list of incidents, but a clear look at where control is being gained, lost, or quietly tested. ⚡ Threat of the Week Lumma Stealer, DanaBot Operations Disrupted — A coalition of private sector companies and law enforcement agencies have taken down the infrastructure associated with Lumma Stealer and DanaBot .

The malware is equipped to siphon data from victim computers, hijack banking session...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday revealed that Commvault is monitoring cyber threat activity targeting applications hosted in their Microsoft Azure cloud environment. "Threat actors may have accessed client secrets for Commvault's (Metallic) Microsoft 365 (M365) backup software-as-a-service (SaaS) solution, hosted in Azure," the agency said . "This provided the threat actors with unauthorized access to Commvault's customers' M365 environments that have application secrets stored by Commvault." CISA further noted that the activity may be part of a broader campaign targeting various software-as-a-service (SaaS) providers' cloud infrastructures with default configurations and elevated permissions. The advisory comes weeks after Commvault revealed that Microsoft notified the company in February 2025 of unauthorized activity by a nation-state threat actor within its Azure environment. The incident led to th...

Cybersecurity researchers have discovered an indirect prompt injection flaw in GitLab's artificial intelligence (AI) assistant Duo that could have allowed attackers to steal source code and inject untrusted HTML into its responses, which could then be used to direct victims to malicious websites. GitLab Duo is an artificial intelligence (AI)-powered coding assistant that enables users to write, review, and edit code. Built using Anthropic's Claude models, the service was first launched in June 2023. But as Legit Security found , GitLab Duo Chat has been susceptible to an indirect prompt injection flaw that permits attackers to "steal source code from private projects, manipulate code suggestions shown to other users, and even exfiltrate confidential, undisclosed zero-day vulnerabilities." Prompt injection refers to a class of vulnerabilities common in AI systems that enable threat actors to weaponize large language models (LLMs) to manipulate responses to user...

A recently patched pair of security flaws affecting Ivanti Endpoint Manager Mobile (EPMM) software has been exploited by a China-nexus threat actor to target a wide range of sectors across Europe, North America, and the Asia-Pacific region. The vulnerabilities, tracked as CVE-2025-4427 (CVSS score: 5.3) and CVE-2025-4428 (CVSS score: 7.2), could be chained to execute arbitrary code on a vulnerable device without requiring any authentication. They were addressed by Ivanti last week. Now, according to a report from EclecticIQ, the vulnerability chain has been abused by UNC5221 , a Chinese cyber espionage group known for its targeting of edge network appliances since at least 2023. Most recently, the hacking crew was also attributed to exploitation efforts targeting SAP NetWeaver instances susceptible to CVE-2025-31324. The Dutch cybersecurity company said the earliest exploitation activity dates back to May 15, 2025, with the attacks targeting healthcare, telecommunications, avia...

A sprawling operation undertaken by global law enforcement agencies and a consortium of private sector firms has disrupted the online infrastructure associated with a commodity information stealer known as Lumma (aka LummaC or LummaC2), seizing 2,300 domains that acted as the command-and-control (C2) backbone to commandeer infected Windows systems. "Malware like LummaC2 is deployed to steal sensitive information such as user login credentials from millions of victims in order to facilitate a host of crimes, including fraudulent bank transfers and cryptocurrency theft," the U.S. Department of Justice (DoJ) said in a statement. The confiscated infrastructure has been used to target millions across the world through affiliates and other cyber criminals. Lumma Stealer, active since late 2022, is estimated to have been used in at least 1.7 million instances to steal information, such as browser data, autofill information, login credentials, and cryptocurrency seed phrases.

Google has announced a new feature in its Chrome browser that lets its built-in Password Manager automatically change a user's password when it detects the credentials to be compromised. "When Chrome detects a compromised password during sign in, Google Password Manager prompts the user with an option to fix it automatically," Google's Ashima Arora, Chirag Desai, and Eiji Kitamura said . "On supported websites, Chrome can generate a strong replacement and update the password for the user automatically." The feature builds upon Password Manager 's existing capabilities to generate strong passwords during sign-up and flag credentials that have been detected in a data breach. Google told The Hacker News the feature hasn't been formally launched for end users, and that it's mainly geared towards developers so they can optimize their websites for once the feature launches. With the automated password change, Google said the idea is to reduce fric...

In the newly released 2025 State of Pentesting Report , Pentera surveyed 500 CISOs from global enterprises (200 from within the USA) to understand the strategies, tactics, and tools they use to cope with the thousands of security alerts, the persisting breaches and the growing cyber risks they have to handle. The findings reveal a complex picture of progress, challenges, and a shifting mindset about how enterprises approach security testing. More Tools, More Data, More Protection… No Guarantees Over the past year, 45% of enterprises expanded their security technology stacks, with organizations now managing an average of 75 different security solutions​.  Yet despite these layers of security tools, 67% of U.S. enterprises experienced a breach in the past 24 months​.

The official site for RVTools has been hacked to serve a compromised installer for the popular VMware environment reporting utility. "Robware.net and RVTools.com are currently offline. We are working expeditiously to restore service and appreciate your patience," the company said in a statement posted on its website. "Robware.net and RVTools.com are the only authorized and supported websites for RVTools software. Do not search for or download purported RVTools software from any other websites or sources." The development comes after security researcher Aidan Leon revealed that an infected version of the installer downloaded from the website was being used to sideload a malicious DLL that turned out to be a known malware loader called Bumblebee . It's currently not known how long the trojanized version of RVTools had been available for download and how many had installed it before the site was taken offline. In the interim, users are recommended to veri...

Cybersecurity leaders aren't just dealing with attacks—they're also protecting trust, keeping systems running, and maintaining their organization's reputation. This week's developments highlight a bigger issue: as we rely more on digital tools, hidden weaknesses can quietly grow.  Just fixing problems isn't enough anymore—resilience needs to be built into everything from the ground up. That means better systems, stronger teams, and clearer visibility across the entire organization. What's showing up now isn't just risk—it's a clear signal that acting fast and making smart decisions matters more than being perfect. Here's what surfaced—and what security teams can't afford to overlook. ⚡ Threat of the Week Microsoft Fixes 5 Actively Exploited 0-Days — Microsoft addressed a total of 78 security flaws in its Patch Tuesday update for May 2025 last week, out of which five of them have come under active exploitation in the wild. The vulnerabilities include CVE-2025-30397, CVE-2025-...

Cryptocurrency exchange Coinbase has disclosed that unknown cyber actors broke into its systems and stole account data for a small subset of its customers. "Criminals targeted our customer support agents overseas," the company said in a statement. "They used cash offers to convince a small group of insiders to copy data in our customer support tools for less than 1% of Coinbase monthly transacting users." The end goal of the campaign was to put together a list of customers who they contacted by masquerading as Coinbase and deceiving them into handing over their cryptocurrency assets. Coinbase said the threat actors then unsuccessfully attempted to extort the company for $20 million on May 11, 2025, by claiming to have information about certain customer accounts as well as internal documents. In a statement shared with Fortune, Coinbase said the compromised customer agents worked in India and have all been fired.  "No passwords, private keys, or funds w...

Imagine this: Your organization completed its annual penetration test in January, earning high marks for security compliance. In February, your development team deployed a routine software update. By April, attackers had already exploited a vulnerability introduced in that February update, gaining access to customer data weeks before being finally detected. This situation isn't theoretical: it plays out repeatedly as organizations realize that point-in-time compliance testing can't protect against vulnerabilities introduced after the assessment. According to Verizons 2025 Data Breach Investigation Report , the exploitation of vulnerabilities rose 34% year-over-year. While compliance frameworks provide important security guidelines, companies need continuous security validation to identify and remediate new vulnerabilities before attackers can exploit them. Here's what you need to know about pen testing to meet compliance standards — and why you should adopt continuous penetratio...
