Google on Wednesday disclosed that it worked with industry partners to disrupt the infrastructure of a suspected China-nexus cyber espionage group tracked as UNC2814 that breached at least 53 organizations across 42 countries. "This prolific, elusive actor has a long history of targeting international governments and global telecommunications organizations across Africa, Asia, and the Americas," Google Threat Intelligence Group (GTIG) and Mandiant said in a report published today. UNC2814 is also suspected to be linked to additional infections in more than 20 other nations. The tech giant, which has been tracking the threat actor since 2017, has been observed using API calls to communicate with software-as-a-service (SaaS) apps as command-and-control (C2) infrastructure. The idea, it added, is to disguise their malicious traffic as benign. Central to the hacking group's operations is a novel backdoor dubbed GRIDTIDE that abuses Google Sheets API as a communication c...

Cybersecurity researchers have discovered four malicious NuGet packages that are designed to target ASP.NET web application developers to steal sensitive data. The campaign, discovered by Socket , exfiltrates ASP.NET Identity data , including user accounts, role assignments, and permission mappings, as well as manipulates authorization rules to create persistent backdoors in victim applications. The names of the packages are listed below - NCryptYo DOMOAuth2_ IRAOAuth2.0 SimpleWriter_ The NuGet packages were published to the repository between August 12 and 21, 2024, by a user named hamzazaheer . They have since been taken down from the repository following responsible disclosure, but not before attracting more than 4,500 downloads. According to the software supply chain security company, NCryptYo acts as a first-stage dropper that establishes a local proxy on localhost:7152 that relays traffic to an attacker-controlled command-and-control (C2) server whose address is dyna...

A vulnerability in GitHub Codespaces could have been exploited by bad actors to seize control of repositories by injecting malicious Copilot instructions in a GitHub issue. The artificial intelligence (AI)-driven vulnerability has been codenamed RoguePilot by Orca Security. It has since been patched by Microsoft following responsible disclosure. "Attackers can craft hidden instructions inside a GitHub issue that are automatically processed by GitHub Copilot, giving them silent control of the in-codespaces AI agent," security researcher Roi Nisimi said in a report. The vulnerability has been described as a case of passive or indirect prompt injection where a malicious instruction is embedded within data or content that's processed by the large language model (LLM), causing it to produce unintended outputs or carry out arbitrary actions. The cloud security company also called it a type of AI-mediated supply chain attack that induces the LLM to automatically execute ...

A Russia-aligned threat actor has been observed targeting a European financial institution as part of a social engineering attack to likely facilitate intelligence gathering or financial theft, signaling a possible expansion of the threat actor's targeting beyond Ukraine and into entities supporting the war-torn nation . The activity, which targeted an unnamed entity involved in regional development and reconstruction initiatives, has been attributed to a cybercrime group tracked as UAC-0050 (aka DaVinci Group ). BlueVoyant has designated the name Mercenary Akula to the threat cluster. The attack was observed earlier this month. "The attack spoofed a Ukrainian judicial domain to deliver an email containing a link to a remote access payload," researchers Patrick McHale and Joshua Green said in a report shared with The Hacker News. "The target was a senior legal and policy advisor involved in procurement, a role with privileged insight into institutional operation...

The North Korea-linked Lazarus Group (aka Diamond Sleet and Pompilus) has been observed using Medusa ransomware in an attack targeting an unnamed entity in the Middle East, according to a new report by the Symantec and Carbon Black Threat Hunter Team. Broadcom's threat intelligence division said it also identified the same threat actors mounting an unsuccessful attack against a healthcare organization in the U.S. Medusa is a ransomware-as-a-service (RaaS) operation launched by a cybercrime group known as Spearwing in 2023. The group has claimed more than 366 attacks to date. "Analysis of the Medusa leak site reveals attacks against four healthcare and non-profit organizations in the U.S. since the beginning of November 2025," the company said in a report shared with The Hacker News. "Victims included a non-profit in the mental health sector and an educational facility for autistic children. It is unknown if all these victims were targeted by North Korean opera...

The threat activity cluster known as UnsolicitedBooker has been observed targeting telecommunications companies in Kyrgyzstan and Tajikistan, marking a shift from prior attacks aimed at Saudi Arabian entities. The attacks involve the deployment of two distinct backdoors codenamed LuciDoor and MarsSnake, according to a report published by Positive Technologies last week. "The group used several unique and rare instruments of Chinese origin," researchers Alexander Badaev and Maxim Shamanov said . UnsolicitedBooker was first documented by ESET in May 2025, attributing the China-aligned threat actor to a cyber attack targeting an unnamed international organization in Saudi Arabia with a backdoor dubbed MarsSnake. The group is assessed to be active since at least March 2023 and has a history of targeting organizations in Asia, Africa, and the Middle East. Further analysis of the threat actor has uncovered tactical overlaps with two other clusters, including Space Pirates an...

The Russia-linked state-sponsored threat actor tracked as APT28 has been attributed to a new campaign targeting specific entities in Western and Central Europe. The activity, per S2 Grupo's LAB52 threat intelligence team, was active between September 2025 and January 2026. It has been codenamed Operation MacroMaze . "The campaign relies on basic tooling and the exploitation of legitimate services for infrastructure and data exfiltration," the cybersecurity company said . The attack chains employ spear-phishing emails as a starting point to distribute lure documents that contain a common structural element within their XML, a field named "INCLUDEPICTURE" that points to a webhook[.]site URL that hosts a JPG image. This, in turn, causes the image file to be fetched from the remote server when the document is opened. Put differently, this mechanism acts as a beaconing mechanism akin to a tracking pixel that triggers an outbound HTTP request to the webhook[.]si...

Cybersecurity researchers have disclosed details of a new cryptojacking campaign that uses pirated software bundles as lures to deploy a bespoke XMRig miner program on compromised hosts. "Analysis of the recovered dropper, persistence triggers, and mining payload reveals a sophisticated, multi-stage infection prioritizing maximum cryptocurrency mining hashrate, often destabilizing the victim system," Trellix researcher Aswath A said in a technical report published last week. "Furthermore, the malware exhibits worm-like capabilities, spreading across external storage devices, enabling lateral movement even in air-gapped environments." The entry point of the attack is the use of social engineering decoys, advertising free premium software in the form of pirated software bundles, such as installers for office productivity suites, to trick unsuspecting users into downloading malware-laced executables. The binary acts as the central nervous system of the infectio...

Security news rarely moves in a straight line. This week, it feels more like a series of sharp turns, some happening quietly in the background, others playing out in public view.

Cybersecurity researchers have disclosed what they say is an active "Shai-Hulud-like" supply chain worm campaign that has leveraged a cluster of at least 19 malicious npm packages to enable credential harvesting and cryptocurrency key theft. The campaign has been codenamed SANDWORM_MODE by supply chain security company Socket. As with prior Shai-Hulud attack waves , the malicious code embedded into the packages comes with capabilities to siphon system information, access tokens, environment secrets, and API keys from developer environments and automatically propagate by abusing stolen npm and GitHub identities to extend its reach. "The sample retains Shai-Hulud hallmarks and adds GitHub API exfiltration with DNS fallback, hook-based persistence, SSH propagation fallback, MCP server injection with embedded prompt injection targeting AI coding assistants, and LLM API Key harvesting," the company said . The packages, published to npm by two npm publisher aliases,...

The Iranian hacking group known as MuddyWater (aka Earth Vetala, Mango Sandstorm, and MUDDYCOAST) has targeted several organizations and individuals mainly located across the Middle East and North Africa (MENA) region as part of a new campaign codenamed Operation Olalampo . The activity, first observed on January 26, 2026, has resulted in the deployment of new malware families that share overlapping samples previously identified as used by the threat actor, according to a report published by Group-IB. These include downloaders like GhostFetch and HTTP_VIP, along with a Rust backdoor called CHAR and an advanced implant codenamed GhostBackDoor that's dropped by GhostFetch. "These attacks follow similar patterns and align with the killchains previously observed in MuddyWater attacks; starting with a phishing email with a Microsoft Office document attached to it that contains malicious macro code that decodes the embedded payload and drops it on the system and executes it, pro...

Cybersecurity researchers have disclosed details of a new ClickFix campaign that abuses compromised legitimate sites to deliver a previously undocumented remote access trojan (RAT) called MIMICRAT (aka AstarionRAT). "The campaign demonstrates a high level of operational sophistication: compromised sites spanning multiple industries and geographies serve as delivery infrastructure, a multi-stage PowerShell chain performs ETW and AMSI bypass before dropping a Lua-scripted shellcode loader, and the final implant communicates over HTTPS on port 443 using HTTP profiles that resemble legitimate web analytics traffic," Elastic Security Labs said in a Friday report. According to the enterprise search and cybersecurity company, MIMICRAT is a custom C++ RAT with support for Windows token impersonation, SOCKS5 tunneling, and a set of 22 commands for comprehensive post-exploitation capabilities. The campaign was discovered earlier this month. It's also assessed to share tactic...

The U.S. Federal Bureau of Investigation (FBI) has warned of an increase in ATM jackpotting incidents across the country, leading to losses of more than $20 million in 2025. The agency said 1,900 ATM jackpotting incidents have been reported since 2020, out of which 700 took place last year. In December 2025, the U.S. Department of Justice (DoJ) said about $40.73 million has been collectively lost to jackpotting attacks since 2021. "Threat actors exploit physical and software vulnerabilities in ATMs and deploy malware to dispense cash without a legitimate transaction," the FBI said in a Thursday bulletin. The jackpotting attacks involve the use of specialized malware, such as Ploutus, to infect ATMs and force them to dispense cash. In most cases, cybercriminals have been observed gaining unauthorized access to the machines by opening an ATM face with widely available generic keys. There are at least two different ways by which the malware is deployed: Removing the A...

Cybersecurity researchers have discovered what they say is the first Android malware that abuses Gemini, Google's generative artificial intelligence (AI) chatbot, as part of its execution flow and achieves persistence. The malware has been codenamed PromptSpy by ESET. The malware is equipped to capture lockscreen data, block uninstallation efforts, gather device information, take screenshots, and record screen activity as video. "Gemini is used to analyze the current screen and provide PromptSpy with step-by-step instructions on how to ensure the malicious app remains pinned in the recent apps list, thus preventing it from being easily swiped away or killed by the system," ESET researcher Lukáš Štefanko said in a report published today. "Since Android malware often relies on UI navigation, leveraging generative AI enables the threat actors to adapt to more or less any device, layout, or OS version, which can greatly expand the pool of potential victims." ...

Cybersecurity researchers have disclosed details of a new campaign dubbed CRESCENTHARVEST , likely targeting supporters of Iran's ongoing protests to conduct information theft and long-term espionage. The Acronis Threat Research Unit (TRU) said it observed the activity after January 9, with the attacks designed to deliver a malicious payload that serves as a remote access trojan (RAT) and information stealer to execute commands, log keystrokes, and exfiltrate sensitive data. It's currently not known if any of the attacks were successful. "The campaign exploits recent geopolitical developments to lure victims into opening malicious .LNK files disguised as protest-related images or videos," researchers Subhajeet Singha, Eliad Kimhy, and Darrel Virtusio said in a report published this week. "These files are bundled with authentic media and a Farsi-language report providing updates from 'the rebellious cities of Iran.' This pro- protest framing appears ...

Cybersecurity researchers have disclosed multiple security vulnerabilities in four popular Microsoft Visual Studio Code (VS Code) extensions that, if successfully exploited, could allow threat actors to steal local files and execute code remotely. The extensions, which have been collectively installed more than 125 million times, are Live Server, Code Runner, Markdown Preview Enhanced, and Microsoft Live Preview. "Our research demonstrates that a hacker needs only one malicious extension, or a single vulnerability within one extension, to perform lateral movement and compromise entire organizations," OX Security researchers Moshe Siman Tov Bustan and Nir Zadok said in a report shared with The Hacker News. Details of the vulnerabilities are as follows - CVE-2025-65717 (CVSS score: 9.1) - A vulnerability in Live Server that allows attackers to exfiltrate local files, tricking a developer into visiting a malicious website when the extension is running, causing JavaScrip...

A maximum severity security vulnerability in Dell RecoverPoint for Virtual Machines has been exploited as a zero-day by a suspected China-nexus threat cluster dubbed UNC6201 since mid-2024, according to a new report from Google Mandiant and Google Threat Intelligence Group (GTIG). The activity involves the exploitation of CVE-2026-22769 (CVSS score: 10.0), a case of hard-coded credentials affecting versions prior to 6.0.3.1 HF1. Other products, including RecoverPoint Classic, are not vulnerable to the flaw.
