Malware | Breaking Cybersecurity News | The Hacker News

Cybersecurity researchers have uncovered a Go-based malware called XDigo that has been used in attacks targeting Eastern European governmental entities in March 2025. The attack chains are said to have leveraged a collection of Windows shortcut ( LNK ) files as part of a multi-stage procedure to deploy the malware, French cybersecurity company HarfangLab said . XDSpy is the name assigned to a cyber espionage that's known to target government agencies in Eastern Europe and the Balkans since 2011. It was first documented by the Belarusian CERT in early 2020.  In recent years, companies in Russia and Moldova have been targeted by various campaigns to deliver malware families like UTask, XDDown, and DSDownloader that can download additional payloads and steal sensitive information from compromised hosts. HarfangLab said it observed the threat actor leveraging a remote code execution flaw in Microsoft Windows that's triggered when processing specially crafted LNK files. The v...

Not every risk looks like an attack. Some problems start as small glitches, strange logs, or quiet delays that don't seem urgent—until they are. What if your environment is already being tested, just not in ways you expected? Some of the most dangerous moves are hidden in plain sight. It's worth asking: what patterns are we missing, and what signals are we ignoring because they don't match old playbooks? This week's reports bring those quiet signals into focus—from attacks that bypassed MFA using trusted tools, to supply chain compromises hiding behind everyday interfaces. Here's what stood out across the cybersecurity landscape: ⚡ Threat of the Week Cloudflare Blocks Massive 7.3 Tbps DDoS Attack — Cloudflare said it autonomously blocked the largest distributed denial-of-service (DDoS) attack ever recorded, which hit a peak of 7.3 terabits per second (Tbps). The attack, the company said, targeted an unnamed hosting provider and delivered 37.4 terabytes in 45 seconds. It origi...

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...

Cloudflare on Thursday said it autonomously blocked the largest distributed denial-of-service (DDoS) attack ever recorded, which hit a peak of 7.3 terabits per second (Tbps). The attack, which was detected in mid-May 2025, targeted an unnamed hosting provider. "Hosting providers and critical Internet infrastructure have increasingly become targets of DDoS attacks," Cloudflare's Omer Yoachimik said . "The 7.3 Tbps attack delivered 37.4 terabytes in 45 seconds." Earlier this January, the web infrastructure and security company said it had mitigated a 5.6 Tbps DDoS attack aimed at an unnamed internet service provider (ISP) from Eastern Asia. The attack originated from a Mirai-variant botnet in October 2024. Then in April 2025, Cloudflare revealed it defended against a massive 6.5 Tbps flood that likely emanated from Eleven11bot, a botnet comprising roughly 30,000 webcams and video recorders. The hyper-volumetric attack lasted about 49 seconds. The 7.3 Tbps...

Cybersecurity researchers have uncovered a new campaign in which the threat actors have published more than 67 GitHub repositories that claim to offer Python-based hacking tools, but deliver trojanized payloads instead. The activity, codenamed Banana Squad by ReversingLabs, is assessed to be a continuation of a rogue Python campaign that was identified in 2023 as targeting the Python Package Index (PyPI) repository with bogus packages that were downloaded over 75,000 times and came with information-stealing capabilities on Windows systems. The findings build on a previous report from the SANS's Internet Storm Center in November 2024 that detailed a supposed "steam-account-checker" tool hosted on GitHub, which incorporated stealthy features to download additional Python payloads that can inject malicious code into the Exodus cryptocurrency wallet app and harvest sensitive data to an external server ("dieserbenni[.]ru"). Further analysis of the repository a...

Cybersecurity researchers have exposed the inner workings of an Android malware called AntiDot that has compromised over 3,775 devices as part of 273 unique campaigns. "Operated by the financially motivated threat actor LARVA-398, AntiDot is actively sold as a Malware-as-a-Service (MaaS) on underground forums and has been linked to a wide range of mobile campaigns," PRODAFT said in a report shared with The Hacker News. AntiDot is advertised as a "three-in-one" solution with capabilities to record the device screen by abusing Android's accessibility services, intercept SMS messages, and extract sensitive data from third-party applications. The Android botnet is suspected to be delivered via malicious advertising networks or through highly tailored phishing campaigns based on activity that indicates selective targeting of victims based on language and geographic location. AntiDot was first publicly documented in May 2024 after it was spotted being distribu...

The North Korea-aligned threat actor known as BlueNoroff has been observed targeting an employee in the Web3 sector with deceptive Zoom calls featuring deepfaked company executives to trick them into installing malware on their Apple macOS devices. Huntress, which revealed details of the cyber intrusion, said the attack targeted an unnamed cryptocurrency foundation employee, who received a message from an external contact on Telegram. "The message requested time to speak to the employee, and the attacker sent a Calendly link to set up meeting time," security researchers Alden Schmidt, Stuart Ashenbrenner, and Jonathan Semon said . "The Calendly link was for a Google Meet event, but when clicked, the URL redirects the end user to a fake Zoom domain controlled by the threat actor." After several weeks, the employee is said to have joined a group Zoom meeting that included several deepfakes of known members of the senior leadership of their company, along with oth...

Most cyberattacks today don't start with loud alarms or broken firewalls. They start quietly—inside tools and websites your business already trusts. It's called " Living Off Trusted Sites " (LOTS)—and it's the new favorite strategy of modern attackers. Instead of breaking in, they blend in. Hackers are using well-known platforms like Google, Microsoft, Dropbox, and Slack as launchpads. They hide malicious code inside routine traffic, making it incredibly difficult for traditional defenses to detect them. And here's the scary part: many security teams don't even realize it's happening—until it's too late. Why You're Not Seeing These Attacks LOTS tactics don't look suspicious at first glance. There's no malware signature to flag, and no unusual IP address to trace. It's legitimate traffic—until it's not. Attackers are exploiting: Common business tools like Teams, Zoom, and GitHub Shortened or vanity URLs to redirect users Trusted cloud services to host malicious payloads ...

A new campaign is making use of Cloudflare Tunnel subdomains to host malicious payloads and deliver them via malicious attachments embedded in phishing emails. The ongoing campaign has been codenamed SERPENTINE#CLOUD by Securonix. It leverages "the Cloudflare Tunnel infrastructure and Python-based loaders to deliver memory-injected payloads through a chain of shortcut files and obfuscated scripts," security researcher Tim Peck said in a report shared with The Hacker News. The attack starts with sending payment- or invoice-themed phishing emails bearing a link to a zipped document that contains a Windows shortcut (LNK) file. These shortcuts are disguised as documents to trick victims into opening them, effectively activating the infection sequence. The elaborate multi-step process culminates in the execution of a Python-based shellcode loader that executes payloads packed with the open-source Donut loader entirely in memory. Securonix said the campaign has targeted the...

A new multi-stage malware campaign is targeting Minecraft users with a Java-based malware that employs a distribution-as-service (DaaS) offering called Stargazers Ghost Network . "The campaigns resulted in a multi-stage attack chain targeting Minecraft users specifically," Check Point researchers Jaromír Hořejší and Antonis Terefos said in a report shared with The Hacker News. "The malware was impersonating Oringo and Taunahi, which are 'Scripts and macros tools' (aka cheats). Both the first and second stages are developed in Java and can only be executed if the Minecraft runtime is installed on the host machine." The end goal of the attack is to trick players into downloading a Minecraft mod from GitHub and deliver a .NET information stealer with comprehensive data theft capabilities. The campaign was first detected by the cybersecurity company in March 2025. What makes the activity notable is its use of an illicit offering called the Stargazers Ghost...

Cybersecurity researchers have exposed a previously unknown threat actor known as Water Curse that relies on weaponized GitHub repositories to deliver multi-stage malware. "The malware enables data exfiltration (including credentials, browser data, and session tokens), remote access, and long-term persistence on infected systems," Trend Micro researchers Jovit Samaniego, Aira Marcelo, Mohamed Fahmy, and Gabriel Nicoleta said in an analysis published this week. The "broad and sustained" campaign, first spotted last month, set up repositories offering seemingly innocuous penetration testing utilities, such as SMTP email bomber and Sakura-RAT, but harbored within their Visual Studio project configuration files malicious payloads that are designed to siphon sensitive data. Water Curse's arsenal incorporates a wide range of tools and programming languages, underscoring their cross-functional development capabilities to target the supply chain with "develope...

A now-patched security flaw in Google Chrome was exploited as a zero-day by a threat actor known as TaxOff to deploy a backdoor codenamed Trinper . The attack, observed in mid-March 2025 by Positive Technologies, involved the use of a sandbox escape vulnerability tracked as CVE-2025-2783 (CVSS score: 8.3). Google addressed the flaw later that month after Kaspersky reported in-the-wild exploitation in a campaign dubbed Operation ForumTroll targeting various Russian organizations. "The initial attack vector was a phishing email containing a malicious link," security researchers Stanislav Pyzhov and Vladislav Lunin said . "When the victim clicked the link, it triggered a one-click exploit (CVE-2025-2783), leading to the installation of the Trinper backdoor employed by TaxOff." The phishing email is said to have been disguised as an invitation to the Primakov Readings forum – the same lure detailed by Kaspersky – urging users to click on a link that led to a fake...

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...

Cybersecurity researchers are warning of a new phishing campaign that's targeting users in Taiwan with malware families such as HoldingHands RAT and Gh0stCringe. The activity is part of a broader campaign that delivered the Winos 4.0 malware framework earlier this January by sending phishing messages impersonating Taiwan's National Taxation Bureau, Fortinet FortiGuard Labs said in a report shared with The Hacker News. The cybersecurity company said it identified additional malware samples through continuous monitoring and that it observed the same threat actor, referred to as Silver Fox APT, using malware-laced PDF documents or ZIP files distributed via phishing emails to deliver Gh0stCringe and a malware strain based on HoldingHands RAT. It's worth noting that both HoldingHands RAT (aka Gh0stBins) and Gh0stCringe are variants of a known remote access trojan called Gh0st RAT, which is widely used by Chinese hacking groups. The starting point of the attack is a p...

Cybersecurity researchers have called attention to a new campaign that's actively exploiting a recently disclosed critical security flaw in Langflow to deliver the Flodrix botnet malware. "Attackers use the vulnerability to execute downloader scripts on compromised Langflow servers, which in turn fetch and install the Flodrix malware," Trend Micro researchers Aliakbar Zahravi, Ahmed Mohamed Ibrahim, Sunil Bharti, and Shubham Singh said in a technical report published today. The activity entails the exploitation of CVE-2025-3248 (CVSS score: 9.8), a missing authentication vulnerability in Langflow , a Python-based "visual framework" for building artificial intelligence (AI) applications. Successful exploitation of the flaw could enable unauthenticated attackers to execute arbitrary code via crafted HTTP requests. It was patched by Langflow in March 2025 with version 1.3.0. Last month, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) flagg...

The U.S. Department of Justice (DoJ) said it has filed a civil forfeiture complaint in federal court that targets over $7.74 million in cryptocurrency, non-fungible tokens (NFTs), and other digital assets allegedly linked to a global IT worker scheme orchestrated by North Korea. "For years, North Korea has exploited global remote IT contracting and cryptocurrency ecosystems to evade U.S. sanctions and bankroll its weapons programs," said Sue J. Bai, Head of the Justice Department's National Security Division. The Justice Department said the funds were originally restrained in connection with an April 2023 indictment against Sim Hyon-Sop, a North Korean Foreign Trade Bank (FTB) representative who is believed to have conspired with the IT workers. The IT workers, the department added, gained employment at U.S. cryptocurrency companies using fake identities and then laundered their ill-gotten gains through Sim to further Pyongyang's strategic objectives in violati...

An emerging ransomware strain has been discovered incorporating capabilities to encrypt files as well as permanently erase them, a development that has been described as a "rare dual-threat." "The ransomware features a 'wipe mode,' which permanently erases files, rendering recovery impossible even if the ransom is paid," Trend Micro researchers Maristel Policarpio, Sarah Pearl Camiling, and Sophia Nilette Robles said in a report published last week. The ransomware-as-a-service (RaaS) operation in question is named Anubis, which became active in December 2024, claiming victims across healthcare, hospitality, and construction sectors in Australia, Canada, Peru, and the U.S. Analysis of early, trial samples of the ransomware suggests that the developers initially named it Sphinx, before tweaking the brand name in the final version. It's worth noting that the e-crime crew has no ties to an Android banking trojan and a Python-based backdoor of the s...
