The threat actors behind the Qilin ransomware-as-a-service (RaaS) scheme are now offering legal counsel for affiliates to put more pressure on victims to pay up, as the cybercrime group intensifies its activity and tries to fill the void left by its rivals. The new feature takes the form of a "Call Lawyer" feature on the affiliate panel, per Israeli cybersecurity company Cybereason. The development represents a newfound resurgence of the e-crime group as once-popular ransomware groups like LockBit, Black Cat, RansomHub, Everest, and BlackLock have suffered abrupt cessations, operational failures, and defacements. The group, also tracked as Gold Feather and Water Galura, has been active since October 2022. Data compiled from the dark web leak sites run by ransomware groups shows that Qilin led with 72 victims in April 2025. In May, it is estimated to be behind 55 attacks , putting it behind Safepay (72) and Luna Moth (67). It's also the third most active group after...

Cybersecurity researchers have disclosed a now-patched security flaw in LangChain's LangSmith platform that could be exploited to capture sensitive data, including API keys and user prompts. The vulnerability, which carries a CVSS score of 8.8 out of a maximum of 10.0, has been codenamed AgentSmith by Noma Security. LangSmith is an observability and evaluation platform that allows users to develop, test, and monitor large language model (LLM) applications, including those built using LangChain. The service also offers what's called a LangChain Hub , which acts as a repository for all publicly listed prompts, agents, and models. "This newly identified vulnerability exploited unsuspecting users who adopt an agent containing a pre-configured malicious proxy server uploaded to 'Prompt Hub,'" researchers Sasi Levi and Gal Moyal said in a report shared with The Hacker News. "Once adopted, the malicious proxy discreetly intercepted all user communicatio...

Some of the biggest security problems start quietly. No alerts. No warnings. Just small actions that seem normal but aren't. Attackers now know how to stay hidden by blending in, and that makes it hard to tell when something's wrong. This week's stories aren't just about what was attacked—but how easily it happened. If we're only looking for the obvious signs, what are we missing right in front of us? Here's a look at the tactics and mistakes that show how much can go unnoticed. ⚡ Threat of the Week Apple Zero-Click Flaw in Messages Exploited to Deliver Paragon Spyware — Apple disclosed that a security flaw in its Messages app was actively exploited in the wild to target civil society members in sophisticated cyber attacks.

INTERPOL on Wednesday announced the dismantling of more than 20,000 malicious IP addresses or domains that have been linked to 69 information-stealing malware variants. The joint action, codenamed Operation Secure , took place between January and April 2025, and involved law enforcement agencies from 26 countries to identify servers, map physical networks, and execute targeted takedowns. "These coordinated efforts resulted in the takedown of 79 percent of identified suspicious IP addresses," INTERPOL said in a statement. "Participating countries reported the seizure of 41 servers and over 100 GB of data, as well as the arrest of 32 suspects linked to illegal cyber activities." Vietnamese authorities arrested 18 suspects, and confiscated devices, SIM cards, business registration documents, and money worth $11,500. Further house raids have led to the arrest of another 12 people in Sri Lanka and two individuals in Nauru. The Hong Kong Police, per INTERPOL, iden...

Behind every security alert is a bigger story. Sometimes it's a system being tested. Sometimes it's trust being lost in quiet ways—through delays, odd behavior, or subtle gaps in control. This week, we're looking beyond the surface to spot what really matters. Whether it's poor design, hidden access, or silent misuse, knowing where to look can make all the difference. If you're responsible for protecting systems, data, or people—these updates aren't optional. They're essential. These stories reveal how attackers think—and where we're still leaving doors open. ⚡ Threat of the Week Google Releases Patches for Actively Exploited Chrome 0-Day — Google has released Google Chrome versions 137.0.7151.68/.69 for Windows and macOS, and version 137.0.7151.68 for Linux to address a high-severity out-of-bounds read and write vulnerability in the V8 JavaScript and WebAssembly engine that it said has been exploited in the wild.

India's Central Bureau of Investigation (CBI) has revealed that it has arrested six individuals and dismantled two illegal call centers that were found to be engaging in a sophisticated transnational tech support scam targeting Japanese citizens. The law enforcement agency said it conducted coordinated searches at 19 locations across Delhi, Haryana, and Uttar Pradesh on May 28, 2025, as part of an initiative called Operation Chakra V, which aims to combat cyber-enabled financial crimes. The cybercrime syndicates, per the CBI, defrauded foreign nationals, mainly Japanese citizens, by masquerading as technical support personnel from various multinational corporations, including Microsoft.  "The syndicate operated call centers designed to appear as legitimate customer service centers, through which victims were deceived into believing that their electronic devices were compromised," the agency said . "Under this pretext, victims were coerced into transferring funds ...

The U.S. Department of Justice (DoJ) on Wednesday announced the seizure of cryptocurrency funds and about 145 clearnet and dark web domains associated with an illicit carding marketplace called BidenCash. "The operators of the BidenCash marketplace use the platform to simplify the process of buying and selling stolen credit cards and associated personal information," the DoJ said . "BidenCash administrators charged a fee for every transaction conducted on the website." BidenCash launched in March 2022 to fill the void left by the shutdown of Joker's Stash a year earlier and several other carding forums like UniCC . Since the time it went operational, the illegal bazaar ("bidencash[.]asia," "bidencash[.]bd," and "bidencash[.]ws") is estimated to have supported more than 117,000 customers, facilitated the trafficking of over 15 million payment card numbers and personally identifiable information, and generated no less than $17 mi...

Google has disclosed details of a financially motivated threat cluster that it said "specializes" in voice phishing (aka vishing ) campaigns designed to breach organizations' Salesforce instances for large-scale data theft and subsequent extortion. The tech giant's threat intelligence team is tracking the activity under the moniker UNC6040 , which it said exhibits characteristics that align with threat groups with ties to an online cybercrime collective known as The Com . "Over the past several months, UNC6040 has demonstrated repeated success in breaching networks by having its operators impersonate IT support personnel in convincing telephone-based social engineering engagements," the company said in a report shared with The Hacker News. This approach, Google's Threat Intelligence Group (GTIG) added, has had the benefit of tricking English-speaking employees into performing actions that give the threat actors access or lead to the sharing of valua...

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 .

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...

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.

"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 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.
