At least six organizations in South Korea have been targeted by the prolific North Korea-linked Lazarus Group as part of a campaign dubbed Operation SyncHole . The activity targeted South Korea's software, IT, financial, semiconductor manufacturing, and telecommunications industries, according to a report from Kaspersky published today. The earliest evidence of compromise was first detected in November 2024. The campaign involved a "sophisticated combination of a watering hole strategy and vulnerability exploitation within South Korean software," security researchers Sojun Ryu and Vasily Berdnikov said . "A one-day vulnerability in Innorix Agent was also used for lateral movement." The attacks have been observed paving the way for variants of known Lazarus tools such as ThreatNeedle , AGAMEMNON , wAgent , SIGNBT , and COPPERHEDGE . What makes these intrusions particularly effective is the likely exploitation of a security vulnerability in Cross EX, a legi...

As many as 159 CVE identifiers have been flagged as exploited in the wild in the first quarter of 2025, up from 151 in Q4 2024. "We continue to see vulnerabilities being exploited at a fast pace with 28.3% of vulnerabilities being exploited within 1-day of their CVE disclosure," VulnCheck said in a report shared with The Hacker News. This translates to 45 security flaws that have been weaponized in real-world attacks within a day of disclosure. Fourteen other flaws have been exploited within a month, while another 45 flaws were abused within the span of a year.  The cybersecurity company said a majority of the exploited vulnerabilities have been identified in content management systems (CMSes), followed by network edge devices, operating systems, open-source software, and server software. The breakdown is as follows - Content Management Systems (CMS) (35) Network Edge Devices (29) Operating Systems (24) Open Source Software (14) Server Software (14) The leading...

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...

Multiple threat activity clusters with ties to North Korea (aka Democratic People's Republic of Korea or DPRK) have been linked to attacks targeting organizations and individuals in the Web3 and cryptocurrency space. "The focus on Web3 and cryptocurrency appears to be primarily financially motivated due to the heavy sanctions that have been placed on North Korea," Google-owned Mandiant said in its M-Trends report for 2025 shared with The Hacker News. "These activities aim to generate financial gains, reportedly funding North Korea's weapons of mass destruction (WMD) program and other strategic assets." The cybersecurity firm said DPRK-nexus threat actors have developed custom tools written in a variety of languages such as Golang, C++, and Rust, and are capable of infecting Windows, Linux, and macOS operating systems. At least three threat activity clusters it tracks as UNC1069, UNC4899, and UNC5342 have been found to target members of the cryptocurren...

The Iran-nexus threat actor known as UNC2428 has been observed delivering a backdoor known as MURKYTOUR as part of a job-themed social engineering campaign aimed at Israel in October 2024. Google-owned Mandiant described UNC2428 as a threat actor aligned with Iran that engages in cyber espionage-related operations. The intrusion set is said to have distributed the malware through a "complex chain of deception techniques." "UNC2428's social engineering campaign targeted individuals while posing as a recruitment opportunity from Israeli defense contractor, Rafael," the company said in its annual M-Trends report for 2025. Individuals who expressed interest were redirected to a site that impersonated Rafael, from where they were asked to download a tool to assist with applying for the job. The tool ("RafaelConnect.exe") was an installer dubbed LONEFLEET that, once launched, presented a graphical user interface (GUI) to the victim in order to enter th...

Cybersecurity researchers have revealed that Russian military personnel are the target of a new malicious campaign that distributes Android spyware under the guise of the Alpine Quest mapping software. "The attackers hide this trojan inside modified Alpine Quest mapping software and distribute it in various ways, including through one of the Russian Android app catalogs," Doctor Web said in an analysis. The trojan has been found embedded in older versions of the software and propagated as a freely available variant of Alpine Quest Pro , a paid offering that removes advertising and analytics features. The Russian cybersecurity vendor said it also observed the malware, dubbed Android.Spy.1292.origin, being distributed in the form of an APK file via a fake Telegram channel. While the threat actors initially provided a link for downloading the app in one of the Russian app catalogs through the Telegram channel, the trojanized version was later distributed directly as an A...

Cybersecurity researchers have detailed a malware campaign that's targeting Docker environments with a previously undocumented technique to mine cryptocurrency. The activity cluster, per Darktrace and Cado Security , represents a shift from other cryptojacking campaigns that directly deploy miners like XMRig to illicitly profit off the compute resources. This involves deploying a malware strain that connects to a nascent Web3 service called Teneo, a decentralized physical infrastructure network (DePIN) that allows users to monetize public social media data by running a Community Node in exchange for rewards called Teneo Points , which can be converted into $TENEO Tokens. The node essentially functions as a distributed social media scraper to extract posts from Facebook, X, Reddit, and TikTok. An analysis of artifacts gathered from Darktrace's honeypots has revealed that the attack starts with a request to launch a container image " kazutod/tene:ten " from the ...

As SaaS and cloud-native work reshape the enterprise, the web browser has emerged as the new endpoint. However, unlike endpoints, browsers remain mostly unmonitored, despite being responsible for more than 70% of modern malware attacks . Keep Aware's recent State of Browser Security report highlights major concerns security leaders face with employees using the web browser for most of their work. The reality is that traditional security tools are blind to what happens within the browser , and attackers know it. Key Findings: 70% of phishing campaigns impersonate Microsoft, OneDrive, or Office 365 to exploit user trust. 150+ trusted platforms like Google Docs and Dropbox are being abused to host phishing and exfiltrate data. 10% of AI prompts involve sensitive business content, posing risks across thousands of browser-based AI tools. 34% of file uploads on company devices go to personal accounts, often undetected. New Attack Patterns Bypass Traditional Defenses From phis...

In what has been described as an "extremely sophisticated phishing attack," threat actors have leveraged an uncommon approach that allowed bogus emails to be sent via Google's infrastructure and redirect message recipients to fraudulent sites that harvest their credentials. "The first thing to note is that this is a valid, signed email – it really was sent from no-reply@google.com," Nick Johnson, the lead developer of the Ethereum Name Service (ENS), said in a series of posts on X. "It passes the DKIM signature check, and Gmail displays it without any warnings – it even puts it in the same conversation as other, legitimate security alerts." The email message informs prospective targets of a subpoena from a law enforcement authority asking for unspecified content present in their Google Account and urges them to click on a sites.google[.]com URL in order to "examine the case materials or take measures to submit a protest." The Google Si...

The China-linked cyber espionage group tracked as Lotus Panda has been attributed to a campaign that compromised multiple organizations in an unnamed Southeast Asian country between August 2024 and February 2025. "Targets included a government ministry, an air traffic control organization, a telecoms operator, and a construction company," the Symantec Threat Hunter Team said in a new report shared with The Hacker News. "The attacks involved the use of multiple new custom tools, including loaders, credential stealers, and a reverse SSH tool." The intrusion set is also said to have targeted a news agency located in another country in Southeast Asia and an air freight organization located in another neighboring country.  The threat cluster, per Broadcom's cybersecurity division, is assessed to be a continuation of a campaign that was disclosed by the company in December 2024 as targeting various high-profile organizations in Southeast Asia since at least Oct...

Cybersecurity researchers have flagged a new malicious campaign related to the North Korean state-sponsored threat actor known as Kimsuky that exploits a now-patched vulnerability impacting Microsoft Remote Desktop Services to gain initial access. The activity has been named Larva-24005 by the AhnLab Security Intelligence Center (ASEC). "In some systems, initial access was gained through exploiting the RDP vulnerability (BlueKeep, CVE-2019-0708)," the South Korean cybersecurity company said . "While an RDP vulnerability scanner was found in the compromised system, there is no evidence of its actual use." CVE-2019-0708 (CVSS score: 9.8) is a critical wormable bug in Remote Desktop Services that could enable remote code execution, allowing unauthenticated attackers to install arbitrary programs, access data, and even create new accounts with full user rights. However, in order for an adversary to exploit the flaw, they would need to send a specially crafted...

A new Android malware-as-a-service (MaaS) platform named SuperCard X can facilitate near-field communication ( NFC ) relay attacks, enabling cybercriminals to conduct fraudulent cashouts. The active campaign is targeting customers of banking institutions and card issuers in Italy with an aim to compromise payment card data, fraud prevention firm Cleafy said in an analysis. There is evidence to suggest that the service is promoted on Telegram channels. SuperCard X "employs a multi-stage approach combining social engineering (via smishing and phone calls), malicious application installation, and NFC data interception for highly effective fraud," security researchers Federico Valentini‍, Alessandro Strino, and Michele Roviello said . The new Android malware, the work of a Chinese-speaking threat actor, has been observed being propagated via three different bogus apps, duping victims into installing them via social engineering techniques like deceptive SMS or WhatsApp mess...

Can a harmless click really lead to a full-blown cyberattack? Surprisingly, yes — and that's exactly what we saw in last week's activity. Hackers are getting better at hiding inside everyday actions: opening a file, running a project, or logging in like normal. No loud alerts. No obvious red flags. Just quiet entry through small gaps — like a misconfigured pipeline, a trusted browser feature, or reused login tokens. These aren't just tech issues — they're habits being exploited. Let's walk through the biggest updates from the week and what they mean for your security. ⚡ Threat of the Week Recently Patched Windows Flaw Comes Under Active Exploitation — A recently patched security flaw affecting Windows NTLM has been exploited by malicious actors to leak NTLM hashes or user passwords and infiltrate systems since March 19, 2025. The flaw, CVE-2025-24054 (CVSS score: 6.5), is a hash disclosure spoofing bug that was fixed by Microsoft last month as part of its Patch Tuesday updates...
