A Pakistan-nexus threat actor has been observed targeting Indian government entities as part of spear-phishing attacks designed to deliver a Golang-based malware known as DeskRAT . The activity, observed in August and September 2025 by Sekoia, has been attributed to Transparent Tribe (aka APT36), a state-sponsored hacking group known to be active since at least 2013. It also builds upon a prior campaign disclosed by CYFIRMA in August 2025. The attack chains involve sending phishing emails containing a ZIP file attachment, or in some cases, a link pointing to an archive hosted on legitimate cloud services like Google Drive. Present within the ZIP file is a malicious Desktop file embedding commands to display a decoy PDF ("CDS_Directive_Armed_Forces.pdf") using Mozilla Firefox while simultaneously executing the main payload. Both the artifacts are pulled from an external server "modgovindia[.]com" and executed. Like before, the campaign is designed to target BO...

Threat actors with ties to North Korea have been attributed to a new wave of attacks targeting European companies active in the defense industry as part of a long-running campaign known as Operation Dream Job . "Some of these [companies] are heavily involved in the unmanned aerial vehicle (UAV) sector, suggesting that the operation may be linked to North Korea's current efforts to scale up its drone program," ESET security researchers Peter Kálnai and Alexis Rapin said in a report shared with The Hacker News. It's assessed that the end goal of the campaign is to plunder proprietary information and manufacturing know-how using malware families such as ScoringMathTea and MISTPEN. The Slovak cybersecurity company said it observed the campaign starting in late March 2025. Some of the targeted entities include a metal engineering company in Southeastern Europe, a manufacturer of aircraft components in Central Europe, and a defense company in Central Europe. While Sc...

The Iranian nation-state group known as MuddyWater has been attributed to a new campaign that has leveraged a compromised email account to distribute a backdoor called Phoenix to various organizations across the Middle East and North Africa (MENA) region, including over 100 government entities. The end goal of the campaign is to infiltrate high-value targets and facilitate intelligence gathering, Singaporean cybersecurity company Group-IB said in a technical report published today. More than three-fourths of the campaign's targets include embassies, diplomatic missions, foreign affairs ministries, and consulates, followed by international organizations and telecommunications firms. "MuddyWater accessed the compromised mailbox through NordVPN (a legitimate service abused by the threat actor), and used it to send phishing emails that appeared to be authentic correspondence," said security researchers Mahmoud Zohdy and Mansour Alhmoud. "By exploiting the trust a...

Threat actors with ties to China exploited the ToolShell security vulnerability in Microsoft SharePoint to breach a telecommunications company in the Middle East after it was publicly disclosed and patched in July 2025. Also targeted were government departments in an African country, as well as government agencies in South America, a university in the U.S., as well as likely a state technology agency in an African country, a government department in the Middle East, and a finance company in a European country. According to Broadcom's Symantec Threat Hunter Team, the attacks involved the exploitation of CVE-2025-53770 , a now-patched security flaw in on-premise SharePoint servers that could be used to bypass authentication and achieve remote code execution. CVE-2025-53770, assessed to be a patch bypass for CVE-2025-49704 and CVE-2025-49706, has been weaponized as a zero-day by three Chinese threat groups , including Linen Typhoon (aka Budworm), Violet Typhoon (aka Sheathminer)...

Government, financial, and industrial organizations located in Asia, Africa, and Latin America are the target of a new campaign dubbed PassiveNeuron , according to findings from Kaspersky. The cyber espionage activity was first flagged by the Russian cybersecurity vendor in November 2024, when it disclosed a set of attacks aimed at government entities in Latin America and East Asia in June, using never-before-seen malware families tracked as Neursite and NeuralExecutor. It also described the operation as exhibiting a high level of sophistication, with the threat actors leveraging already compromised internal servers as an intermediate command-and-control (C2) infrastructure to fly under the radar. "The threat actor is able to move laterally through the infrastructure and exfiltrate data, optionally creating virtual networks that allow attackers to steal files of interest even from machines isolated from the internet," Kaspersky noted at the time. "A plugin-based ap...

A new malware attributed to the Russia-linked hacking group known as COLDRIVER has undergone numerous developmental iterations since May 2025, suggesting an increased "operations tempo" from the threat actor. The findings come from Google Threat Intelligence Group (GTIG), which said the state-sponsored hacking crew has rapidly refined and retooled its malware arsenal merely five days following the publication of its LOSTKEYS malware around the same time. While it's currently not known for how long the new malware families have been under development, the tech giant's threat intelligence team said it has not observed a single instance of LOSTKEYS since disclosure. The new malware, codenamed NOROBOT, YESROBOT, and MAYBEROBOT, is "a collection of related malware families connected via a delivery chain," GTIG researcher Wesley Shields said in a Monday analysis. The latest attack waves are something of a departure from COLDRIVER's typical modus opera...

A European telecommunications organization is said to have been targeted by a threat actor that aligns with a China-nexus cyber espionage group known as Salt Typhoon . The organization, per Darktrace , was targeted in the first week of July 2025, with the attackers exploiting a Citrix NetScaler Gateway appliance to obtain initial access. Salt Typhoon, also known as Earth Estries, FamousSparrow, GhostEmperor, and UNC5807, is the name given to an advanced persistent threat actor with ties to China. Known to be active since 2019, the group gained prominence last year following its attacks on telecommunications services providers, energy networks, and government systems in the U.S. The adversary has a track record of exploiting security flaws in edge devices, maintaining deep persistence, and exfiltrating sensitive data from victims in more than 80 countries across North America, Europe, the Middle East, and Africa. In the incident observed against the European telecommunications enti...

China on Sunday accused the U.S. National Security Agency (NSA) of carrying out a "premeditated" cyber attack targeting the National Time Service Center ( NTSC ), as it described the U.S. as a "hacker empire" and the "greatest source of chaos in cyberspace." The Ministry of State Security (MSS), in a WeChat post , said it uncovered "irrefutable evidence" of the agency's involvement in the intrusion that dated back to March 25, 2022. The attack was ultimately foiled, it added. Established in 1966 under the jurisdiction of the Chinese Academy of Sciences (CAS), NTSC is responsible for generating, maintaining, and transmitting the national standard of time (Beijing Time). "Any cyberattack damaging these facilities would jeopardize the secure and stable operation of 'Beijing Time,' triggering severe consequences such as network communication failures, financial system disruptions, power supply interruptions, transportation paraly...

A threat actor with ties to the Democratic People's Republic of Korea (aka North Korea) has been observed leveraging the EtherHiding technique to distribute malware and enable cryptocurrency theft, marking the first time a state-sponsored hacking group has embraced the method. The activity has been attributed by Google Threat Intelligence Group (GTIG) to a threat cluster it tracks as UNC5342 , which is also known as CL-STA-0240 (Palo Alto Networks Unit 42), DeceptiveDevelopment (ESET), DEV#POPPER (Securonix), Famous Chollima (CrowdStrike), Gwisin Gang (DTEX), Tenacious Pungsan (Datadog), and Void Dokkaebi (Trend Micro). The attack wave is part of a long-running campaign codenamed Contagious Interview , wherein the attackers approach potential targets on LinkedIn by posing as recruiters or hiring managers, and trick them into running malicious code under the pretext of a job assessment after shifting the conversation to Telegram or Discord. The end goal of these efforts is to ...

A threat actor with ties to China has been attributed to a five-month-long intrusion targeting a Russian IT service provider, marking the hacking group's expansion to the country beyond Southeast Asia and South America. The activity, which took place from January to May 2025, has been attributed by Broadcom-owned Symantec to a threat actor it tracks as Jewelbug , which it said overlaps with clusters known as CL-STA-0049 (Palo Alto Networks Unit 42), Earth Alux (Trend Micro), and REF7707 (Elastic Security Labs). The findings suggest Russia is not off-limits for Chinese cyber espionage operations despite increased "military, economic, and diplomatic" relations between Moscow and Beijing over the years. "Attackers had access to code repositories and software build systems that they could potentially leverage to carry out supply chain attacks targeting the company's customers in Russia," the Symantec Threat Hunter Team said in a report shared with The ...

Threat actors with ties to China have been attributed to a novel campaign that compromised an ArcGIS system and turned it into a backdoor for more than a year. The activity, per ReliaQuest, is the handiwork of a Chinese state-sponsored hacking group called Flax Typhoon , which is also tracked as Ethereal Panda and RedJuliett. According to the U.S. government, it's assessed to be a publicly-traded, Beijing-based company known as Integrity Technology Group. "The group cleverly modified a geo-mapping application's Java server object extension (SOE) into a functioning web shell," the cybersecurity company said in a report shared with The Hacker News. "By gating access with a hardcoded key for exclusive control and embedding it in system backups, they achieved deep, long-term persistence that could survive a full system recovery." Flax Typhoon is known for living up to the "stealth" in its tradecraft by extensively incorporating living-off-the-l...

A China-aligned threat actor codenamed UTA0388 has been attributed to a series of spear-phishing campaigns targeting North America, Asia, and Europe that are designed to deliver a Go-based implant known as GOVERSHELL . "The initially observed campaigns were tailored to the targets, and the messages purported to be sent by senior researchers and analysts from legitimate-sounding, completely fabricated organizations," Volexity said in a Wednesday report. "The goal of these spear phishing campaigns was to socially engineer targets into clicking links that led to a remotely hosted archive containing a malicious payload." Since then, the threat actor behind the attacks is said to have leveraged different lures and fictional identities, spanning several languages, including English, Chinese, Japanese, French, and German. Early iterations of the campaigns have been found to embed links to phishing content either hosted on a cloud-based service or their own infrastruc...

A Chinese company named the Beijing Institute of Electronics Technology and Application (BIETA) has been assessed to be likely led by the Ministry of State Security (MSS). The assessment comes from evidence that at least four BIETA personnel have clear or possible links to MSS officers and their relationship with the University of International Relations, which is known to share links with the MSS, according to Recorded Future. The names of the four individuals include Wu Shizhong, He Dequan, You Xingang, and Zhou Linna. "BIETA and its subsidiary, Beijing Sanxin Times Technology Co., Ltd. (CIII), research, develop, import, and sell technologies that almost certainly support intelligence, counterintelligence, military, and other missions relevant to China's national development and security," the company said in a report shared with The Hacker News. "Their activities include researching methods of steganography that can likely support covert communications (COVCOM) a...

The threat actor known as Confucius has been attributed to a new phishing campaign that has targeted Pakistan with malware families like WooperStealer and Anondoor. "Over the past decade, Confucius has repeatedly targeted government agencies, military organizations, defense contractors, and critical industries -- especially in Pakistan – using spear-phishing and malicious documents as initial access vectors," Fortinet FortiGuard Labs researcher Cara Lin said . Confucius is a long-running hacking group that's believed to have been active since 2013 and operating across South Asia. Recent campaigns undertaken by the threat actor have employed a Python-based backdoor called Anondoor, signaling an evolution of the group's tradecraft and its technical agility. One of the attack chains documented by Fortinet targeted users in Pakistan sometime in December 2024, tricking recipients into opening a .PPSX file, which then triggers the delivery of WooperStealer using DLL ...

Government and telecommunications organizations across Africa, the Middle East, and Asia have emerged as the target of a previously undocumented China-aligned nation-state actor dubbed Phantom Taurus over the past two-and-a-half years. "Phantom Taurus' main focus areas include ministries of foreign affairs, embassies, geopolitical events, and military operations," Palo Alto Networks Unit 42 researcher Lior Rochberger said . "The group's primary objective is espionage. Its attacks demonstrate stealth, persistence, and an ability to quickly adapt their tactics, techniques, and procedures (TTPs)." It's worth pointing out that the hacking group was first detailed by the cybersecurity company back in June 2023 under the moniker CL-STA-0043 . Then last May, the threat cluster was graduated to a temporary group, TGR-STA-0043 , following revelations about its sustained cyber espionage efforts aimed at governmental entities since at least late 2022 as part of...

Companies in the legal services, software-as-a-service (SaaS) providers, Business Process Outsourcers (BPOs), and technology sectors in the U.S. have been targeted by a suspected China-nexus cyber espionage group to deliver a known backdoor referred to as BRICKSTORM . The activity, attributed to UNC5221 and closely related, suspected China-nexus threat clusters, is designed to facilitate persistent access to victim organizations for over a year, Mandiant and Google Threat Intelligence Group (GTIG) said in a new report shared with The Hacker News. It's assessed that the objective of BRICKSTORM targeting SaaS providers is to gain access to downstream customer environments or the data SaaS providers host on their customers' behalf, while the targeting of the U.S. legal and technological spheres is likely an attempt to gather information related to national security and international trade, as well as steal intellectual property to advance the development of zero-day exploits. ...

An Iran-nexus cyber espionage group known as UNC1549 has been attributed to a new campaign targeting European telecommunications companies, successfully infiltrating 34 devices across 11 organizations as part of a recruitment-themed activity on LinkedIn. Swiss cybersecurity company PRODAFT is tracking the cluster under the name Subtle Snail . It's assessed to be affiliated with Iran's Islamic Revolutionary Guard Corps (IRGC). The targeted 11 companies are located in Canada, France, the United Arab Emirates, the United Kingdom, and the United States. "The group operates by posing as HR representatives from legitimate entities to engage employees, then compromises them through deployment of a MINIBIKE backdoor variant that communicates with command-and-control (C2) infrastructure proxied through Azure cloud services to bypass detection," the company said in a report shared with The Hacker News. UNC1549 (aka TA455), believed to be active since at least June 2022, ...

Cybersecurity researchers have discerned evidence of two Russian hacking groups Gamaredon and Turla collaborating together to target and co-comprise Ukrainian entities. Slovak cybersecurity company ESET said it observed the Gamaredon tools PteroGraphin and PteroOdd being used to execute Turla group's Kazuar backdoor on an endpoint in Ukraine in February 2025, indicating that Turla is very likely actively collaborating with Gamaredon to gain access to specific machines in Ukraine and deliver the Kazuar backdoor.  "PteroGraphin was used to restart the Kazuar v3 backdoor, possibly after it crashed or was not launched automatically," ESET said in a report shared with The Hacker News. "Thus, PteroGraphin was probably used as a recovery method by Turla." In a separate instance in April and June 2025, ESET said it also detected the deployment of Kazuar v2 through two other Gamaredon malware families tracked as PteroOdd and PteroPaste. Both Gamaredon (aka Aqua B...
