The North Korea-linked threat actor known as UNC4899 has been attributed to attacks targeting two different organizations by approaching their employees via LinkedIn and Telegram. "Under the guise of freelance opportunities for software development work, UNC4899 leveraged social engineering techniques to successfully convince the targeted employees to execute malicious Docker containers in their respective workstations," Google's cloud division said [PDF] in its Cloud Threat Horizons Report for H2 2025. UNC4899 overlaps with activity tracked under the monikers Jade Sleet, PUKCHONG, Slow Pisces, and TraderTraitor. Active since at least 2020, the state-sponsored actor is known for its targeting of cryptocurrency and blockchain industries. Notably, the hacking group has been implicated in significant cryptocurrency heists , including that of Axie Infinity in March 2022 ($625 million), DMM Bitcoin in May 2024 ($308 million), and Bybit in February 2025 ($1.4 billion). ...

Cybersecurity researchers are calling attention to an ongoing campaign that distributes fake cryptocurrency trading apps to deploy a compiled V8 JavaScript (JSC) malware called JSCEAL that can capture data such as credentials and wallets. The activity leverages thousands of malicious advertisements posted on Facebook in an attempt to redirect unsuspecting victims to counterfeit sites that instruct them to install the bogus apps, according to Check Point. These ads are shared either via stolen accounts or newly created ones. "The actors separate the installer's functionality into different components and most notably move some functionality to the JavaScript files inside the infected websites," the company said in an analysis. "A modular, multi-layered infection flow enables the attackers to adapt new tactics and payloads at every stage of the operation." It's worth noting that some aspects of the activity were previously documented by Microsoft in April 2...

A newly emerged ransomware-as-a-service (RaaS) gang called Chaos is likely made up of former members of the BlackSuit crew , as the latter's dark web infrastructure has been the subject of a law enforcement seizure. Chaos, which sprang forth in February 2025, is the latest entrant in the ransomware landscape to conduct big-game hunting and double extortion attacks. "Chaos RaaS actors initiated low-effort spam flooding, escalating to voice-based social engineering for access, followed by RMM tool abuse for persistent connection and legitimate file-sharing software for data exfiltration," Cisco Talos researchers Anna Bennett, James Nutland, and Chetan Raghuprasad said . "The ransomware utilizes multi-threaded rapid selective encryption, anti-analysis techniques, and targets both local and network resources, maximizing impact while hindering detection and recovery." It's important to note here that the ransomware group is unrelated to the Chaos ransomware ...

Python supply chain attacks are surging in 2025. Join our webinar to learn how to secure your code, dependencies, and runtime with modern tools and strategies.

Some risks don't breach the perimeter—they arrive through signed software, clean resumes, or sanctioned vendors still hiding in plain sight. This week, the clearest threats weren't the loudest—they were the most legitimate-looking. In an environment where identity, trust, and tooling are all interlinked, the strongest attack path is often the one that looks like it belongs. Security teams are now challenged to defend systems not just from intrusions—but from trust itself being turned into a weapon. ⚡ Threat of the Week Microsoft SharePoint Attacks Traced to China — The fallout from an attack spree targeting defects in on-premises Microsoft SharePoint servers continues to spread a week after the discovery of the zero-day exploits, with more than 400 organizations globally compromised. The attacks have been attributed to two known Chinese hacking groups tracked as Linen Typhoon (aka APT27), Violet Typhoon (aka APT31), and a suspected China-based threat actor codenamed Storm-2603 t...

The threat actor behind the exploitation of vulnerable Craft Content Management System (CMS) instances has shifted its tactics to target Magento CMS and misconfigured Docker instances. The activity has been attributed to a threat actor tracked as Mimo (aka Hezb), which has a long history of leveraging N-day security flaws in various web applications to deploy cryptocurrency miners. "Although Mimo's primary motivation remains financial, through cryptocurrency mining and bandwidth monetization, the sophistication of their recent operations suggests potential preparation for more lucrative criminal activities," Datadog Security Labs said in a report published this week. Mimo's exploitation of CVE-2025-32432, a critical security flaw in Craft CMS, for cryptojacking and proxyjacking was documented by Sekoia in May 2025. Newly observed attack chains associated with the threat actor involve the abuse of undetermined PHP-FPM vulnerabilities in Magento e-commerce inst...

The Windows banking trojan known as Coyote has become the first known malware strain to exploit the Windows accessibility framework called UI Automation (UIA) to harvest sensitive information. "The new Coyote variant is targeting Brazilian users, and uses UIA to extract credentials linked to 75 banking institutes' web addresses and cryptocurrency exchanges," Akamai security researcher Tomer Peled said in an analysis. Coyote, first revealed by Kaspersky in 2024, is known for targeting Brazilian users. It comes with capabilities to log keystrokes, capture screenshots, and serve overlays on top of login pages associated with financial enterprises. Part of the Microsoft .NET Framework, UIA is a legitimate feature offered by Microsoft to allow screen readers and other assistive technology products to programmatically access user interface (UI) elements on a desktop.  That UIA can be a potential pathway for abuse, including data theft, was previously demonstrated as a...

The financially motivated threat actor known as EncryptHub (aka LARVA-208 and Water Gamayun) has been attributed to a new campaign that's targeting Web3 developers to infect them with information stealer malware. "LARVA-208 has evolved its tactics, using fake AI platforms (e.g., Norlax AI, mimicking Teampilot) to lure victims with job offers or portfolio review requests," Swiss cybersecurity company PRODAFT said in a statement shared with The Hacker News. While the group has a history of deploying ransomware, the latest findings demonstrate an evolution of its tactics and a diversification of its monetization methods by using stealer malware to harvest data from cryptocurrency wallets. EncryptHub's focus on Web3 developers isn't random—these individuals often manage crypto wallets, access to smart contract repositories, or sensitive test environments. Many operate as freelancers or work across multiple decentralized projects, making them harder to protect wit...

Cybersecurity researchers have discovered a new campaign that exploits a known security flaw impacting Apache HTTP Server to deliver a cryptocurrency miner called Linuxsys . The vulnerability in question is CVE-2021-41773 (CVSS score: 7.5), a high-severity path traversal vulnerability in Apache HTTP Server version 2.4.49 that could result in remote code execution. "The attacker leverages compromised legitimate websites to distribute malware, enabling stealthy delivery and evasion of detection," VulnCheck's Jacob Baines said in a report shared with The Hacker News. The infection sequence, observed earlier this month and originating from an Indonesian IP address 103.193.177[.]152 , is designed to drop a next-stage payload from "repositorylinux[.]org" using curl or wget. The payload is a shell script that's responsible for downloading the Linuxsys cryptocurrency miner from five different legitimate websites, suggesting that the threat actors behind the ...

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...

Cryptocurrency users are the target of an ongoing social engineering campaign that employs fake startup companies to trick users into downloading malware that can drain digital assets from both Windows and macOS systems. "These malicious operations impersonate AI, gaming, and Web3 firms using spoofed social media accounts and project documentation hosted on legitimate platforms like Notion and GitHub," Darktrace researcher Tara Gould said in a report shared with The Hacker News. The elaborate social media scam has been for sometime now, with a previous iteration in December 2024 leveraging bogus videoconferencing platforms to dupe victims into joining a meeting under the pretext of discussing an investment opportunity after approaching them on messaging apps like Telegram. Users who ended up downloading the purported meeting software were stealthily infected by stealer malware such as Realst. The campaign was codenamed Meeten by Cado Security (which was acquired by Dark...

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) on Tuesday sanctioned a member of a North Korean hacking group called Andariel for their role in the infamous remote information technology (IT) worker scheme. The Treasury said Song Kum Hyok, a 38-year-old North Korean national with an address in the Chinese province of Jilin, enabled the fraudulent operation by using foreign-hired IT workers to seek remote employment with U.S. companies and planning to split income with them. Between 2022 and 2023, Song is alleged to have used the identities of U.S. people, including their names, addresses, and Social Security numbers, to craft aliases for the hired workers, who then used these personas to pose as U.S. nationals looking for remote jobs in the country. The development comes days after the U.S. Department of Justice (DoJ) announced sweeping actions targeting the North Korean information technology (IT) worker scheme, leading to the arrest of one indi...

A newly released report by cybersecurity firm CTM360 reveals a large-scale scam operation utilizing fake news websites—known as Baiting News Sites (BNS)—to deceive users into online investment fraud across 50 countries. These BNS pages are made to look like real news outlets: CNN, BBC, CNBC, or regional media. They publish fake stories that feature public figures, central banks, or financial brands, all claiming to back new ways to earn passive income. The goal? Build trust quickly and steer readers toward professional-looking scam platforms like Trap10, Solara Vynex, or Eclipse Earn. Scammers use sponsored ads on Google, Meta, and blog networks to push traffic to these sites. Ads often carry clickbait headlines—"You won't believe what a prominent public figure just revealed"—paired with official photos or national flags to make them feel legit. Clicking the ad directs users to a fake article, which then redirects them to a fraudulent trading platform. Many of these scams follow a...

Cybersecurity researchers have disclosed a malicious campaign that leverages search engine optimization ( SEO ) poisoning techniques to deliver a known malware loader called Oyster (aka Broomstick or CleanUpLoader). The malvertising activity, per Arctic Wolf, promotes fake websites hosting trojanized versions of legitimate tools like PuTTY and WinSCP, aiming to trick software professionals searching for these programs into installing them instead. "Upon execution, a backdoor known as Oyster/Broomstick is installed," the company said in a brief published last week. "Persistence is established by creating a scheduled task that runs every three minutes, executing a malicious DLL (twain_96.dll) via rundll32.exe using the DllRegisterServer export, indicating the use of DLL registration as part of the persistence mechanism." The names of some of the bogus websites are listed below - updaterputty[.]com zephyrhype[.]com putty[.]run putty[.]bet, and puttyy[.]org...

Threat actors are weaponizing exposed Java Debug Wire Protocol ( JDWP ) interfaces to obtain code execution capabilities and deploy cryptocurrency miners on compromised hosts. "The attacker used a modified version of XMRig with a hard-"coded configuration, allowing them to avoid suspicious command-line arguments that are often flagged by defenders," Wiz researchers Yaara Shriki and Gili Tikochinski said in a report published this week. "The payload used mining pool proxies to hide their cryptocurrency wallet address, thereby preventing investigators from pivoting on it." The cloud security firm, which is being acquired by Google Cloud, said it observed the activity against its honeypot servers running TeamCity, a popular continuous integration and continuous delivery (CI/CD) tool. JDWP is a communication protocol used in Java for debugging purposes. With JDWP, users can leverage a debugger to work in a different process, a Java application, on the same com...

Cybersecurity researchers have uncovered over 40 malicious browser extensions for Mozilla Firefox that are designed to steal cryptocurrency wallet secrets, putting users' digital assets at risk. "These extensions impersonate legitimate wallet tools from widely-used platforms such as Coinbase, MetaMask, Trust Wallet, Phantom, Exodus, OKX, Keplr, MyMonero, Bitget, Leap, Ethereum Wallet, and Filfox," Koi Security researcher Yuval Ronen said . The large-scale campaign is said to have been ongoing since at least April 2025, with new extensions uploaded to the Firefox Add-ons store as recently as last week. The identified extensions have been found to artificially inflate their popularity, adding hundreds of 5-star reviews that go far beyond the total number of active installations. This strategy is employed to give them an illusion of authenticity, making it seem like they are widely adopted and tricking unsuspecting users into installing them. Another tactic adopted by ...

Threat actors with ties to North Korea have been observed targeting Web3 and cryptocurrency-related businesses with malware written in the Nim programming language, underscoring a constant evolution of their tactics. "Unusually for macOS malware, the threat actors employ a process injection technique and remote communications via wss, the TLS-encrypted version of the WebSocket protocol," SentinelOne researchers Phil Stokes and Raffaele Sabato said in a report shared with The Hacker News. "A novel persistence mechanism takes advantage of SIGINT/SIGTERM signal handlers to install persistence when the malware is terminated or the system rebooted." The cybersecurity company is tracking the malware components collectively under the name NimDoor. It's worth noting that some aspects of the campaign were previously documented by Huntabil.IT and later by Huntress and Validin , but with differences in the payloads deployed. The attack chains involve social enginee...

Europol on Monday announced the takedown of a cryptocurrency investment fraud ring that laundered €460 million ($540 million) from more than 5,000 victims across the world. The international effort, codenamed Operation Borrelli, was carried out by the Spanish Guardia Civil, along with support from law enforcement authorities from Estonia, France, and the United States. Europol said the investigation into the syndicate started in 2023. In addition, the five alleged suspects behind the cryptocurrency scam were arrested on June 25, 2025. Three of the arrests took place in the Canary Islands, while two others were apprehended from Madrid. "To carry out their fraudulent activities, the leaders of the criminal network allegedly used a net of associates spread around the world to raise funds through cash withdrawals, bank transfers, and crypto-transfers," Europol said . These types of scams often follow a pattern known as cryptocurrency confidence or romance baiting (formerly ...

Cybersecurity researchers have uncovered a fresh batch of malicious npm packages linked to the ongoing Contagious Interview operation originating from North Korea.
