Cybersecurity company SentinelOne has revealed that a China-nexus threat cluster dubbed PurpleHaze conducted reconnaissance attempts against its infrastructure and some of its high-value customers. "We first became aware of this threat cluster during a 2024 intrusion conducted against an organization previously providing hardware logistics services for SentinelOne employees," security researchers Tom Hegel, Aleksandar Milenkoski, and Jim Walter said in an analysis published Monday. PurpleHaze is assessed to be a hacking crew with loose ties to another state-sponsored group known as APT15 , which is also tracked as Flea, Nylon Typhoon (formerly Nickel), Playful Taurus, Royal APT, and Vixen Panda. The adversarial collective has also been observed targeting an unnamed South Asian government-supporting entity in October 2024, employing an operational relay box (ORB) network and a Windows backdoor dubbed GoReShell. The implant, written in the Go programming language, repurp...

Google has revealed that it observed 75 zero-day vulnerabilities exploited in the wild in 2024, down from 98 in 2023 but an increase from 63 the year before. Of the 75 zero-days, 44% of them targeted enterprise products. As many as 20 flaws were identified in security software and appliances. "Zero-day exploitation of browsers and mobile devices fell drastically, decreasing by about a third for browsers and by about half for mobile devices compared to what we observed last year," the Google Threat Intelligence Group (GTIG) said in a report shared with The Hacker news. "Exploit chains made up of multiple zero-day vulnerabilities continue to be almost exclusively (~90%) used to target mobile devices." While Microsoft Windows accounted for 22 of the zero-day flaws exploited in 2024, Apple's Safari had three, iOS had two, Android had seven, Chrome had seven, and Mozilla Firefox had one flaw that were abused during the same period. Three of the seven zero-days ...

Cybersecurity researchers are warning about a new malware called DslogdRAT that's installed following the exploitation of a now-patched security flaw in Ivanti Connect Secure (ICS). The malware, along with a web shell, were "installed by exploiting a zero-day vulnerability at that time, CVE-2025-0282, during attacks against organizations in Japan around December 2024," JPCERT/CC researcher Yuma Masubuchi said in a report published Thursday. CVE-2025-0282 refers to a critical security flaw in ICS that could allow unauthenticated remote code execution. It was addressed by Ivanti in early January 2025. However, the shortcoming has been exploited as a zero-day by a China-nexus cyber espionage group dubbed UNC5337 to deliver the SPAWN ecosystem of malware, as well as other tools like DRYHOOK and PHASEJAM. The deployment of the latter two malware strains has not been attributed to any known threat actor. Since then, both JPCERT/CC and the U.S. Cybersecurity and Infrastr...

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...

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...

Cybersecurity researchers have unearthed a new controller component associated with a known backdoor called BPFDoor as part of cyber attacks targeting telecommunications, finance, and retail sectors in South Korea, Hong Kong, Myanmar, Malaysia, and Egypt in 2024. "The controller could open a reverse shell," Trend Micro researcher Fernando Mercês said in a technical report published earlier in the week. "This could allow lateral movement, enabling attackers to enter deeper into compromised networks, allowing them to control more systems or gain access to sensitive data. The campaign has been attributed with medium confidence to a threat group it tracks as Earth Bluecrow, which is also known as DecisiveArchitect, Red Dev 18, and Red Menshen. The lower confidence level boils down to the fact that the BPFDoor malware source code was leaked in 2022 , meaning it could also have bee adopted by other hacking groups. BPFDoor is a Linux backdoor that first came to light in...

A threat actor with ties to Pakistan has been observed targeting various sectors in India with various remote access trojans like Xeno RAT, Spark RAT, and a previously undocumented malware family called CurlBack RAT . The activity, detected by SEQRITE in December 2024, targeted Indian entities under railway, oil and gas, and external affairs ministries, marking an expansion of the hacking crew's targeting footprint beyond government, defence, maritime sectors, and universities. "One notable shift in recent campaigns is the transition from using HTML Application (HTA) files to adopting Microsoft Installer (MSI) packages as a primary staging mechanism," security researcher Sathwik Ram Prakki said . SideCopy is suspected to be a sub-cluster within Transparent Tribe (aka APT36) that's active since at least 2019. It's so named for mimicking the attack chains associated with another threat actor called SideWinder to deliver its own payloads. In June 2024, SEQR...

The Russia-linked threat actor known as Gamaredon (aka Shuckworm) has been attributed to a cyber attack targeting a foreign military mission based in Ukraine with an aim to deliver an updated version of a known malware called GammaSteel. The group targeted the military mission of a Western country, per the Symantec Threat Hunter team, with first signs of the malicious activity detected on February 26, 2025. "The initial infection vector used by the attackers appears to have been an infected removable drive," the Broadcom-owned threat intelligence division said in a report shared with The Hacker News. The attack started with the creation of a Windows Registry value under the UserAssist key, followed by launching "mshta.exe" using "explorer.exe" to initiate a multi-stage infection chain and launch two files. The first file, named "NTUSER.DAT.TMContainer00000000000000000001.regtrans-ms," is used to establish communications with a command-and...

The Computer Emergency Response Team of Ukraine (CERT-UA) has revealed a new set of cyber attacks targeting Ukrainian institutions with information-stealing malware. The activity is aimed at military formations, law enforcement agencies, and local self-government bodies, particularly those located near Ukraine's eastern border, the agency said. The attacks involve distributing phishing emails containing a macro-enabled Microsoft Excel spreadsheet (XLSM), which, when opened, facilities the deployment of two pieces of malware, a PowerShell script taken from the PSSW100AVB ("Powershell Scripts With 100% AV Bypass") GitHub repository that opens a reverse shell, and a previously undocumented stealer dubbed GIFTEDCROOK. "File names and email subject lines reference relevant and sensitive issues such as demining, administrative fines, UAV production, and compensation for destroyed property," CERT-UA said. "These spreadsheets contain malicious code which, ...

Ivanti has disclosed details of a now-patched critical security vulnerability impacting its Connect Secure product that has come under active exploitation in the wild. The vulnerability, tracked as CVE-2025-22457 (CVSS score: 9.0), concerns a case of a stack-based buffer overflow that could be exploited to execute arbitrary code on affected systems. "A stack-based buffer overflow in Ivanti Connect Secure before version 22.7R2.6, Ivanti Policy Secure before version 22.7R1.4, and Ivanti ZTA Gateways before version 22.8R2.2 allows a remote unauthenticated attacker to achieve remote code execution," Ivanti said in an alert released Thursday. The flaw impacts the following products and versions - Ivanti Connect Secure (versions 22.7R2.5 and prior) - Fixed in version 22.7R2.6 (Patch released on February 11, 2025) Pulse Connect Secure (versions 9.1R18.9 and prior) - Fixed in version 22.7R2.6 (Contact Ivanti to migrate as the device has reached end-of-support as of December ...

The Computer Emergency Response Team of Ukraine (CERT-UA) has revealed that no less than three cyber attacks were recorded against state administration bodies and critical infrastructure facilities in the country with an aim to steal sensitive data. The campaign, the agency said , involved the use of compromised email accounts to send phishing messages containing links pointing to legitimate services like DropMeFiles and Google Drive. In some instances, the links are embedded within PDF attachments. The digital missives sought to induce a false sense of urgency by claiming that a Ukrainian government agency planned to cut salaries, urging the recipient to click on the link to view the list of affected employees. Visiting these links leads to the download of a Visual Basic Script (VBS) loader that's designed to fetch and execute a PowerShell script capable of harvesting files matching a specific set of extensions and capturing screenshots. The activity, attributed to a threat ...

Cybersecurity researchers have shed light on a new China-linked threat actor called Earth Alux that has targeted various key sectors such as government, technology, logistics, manufacturing, telecommunications, IT services, and retail in the Asia-Pacific (APAC) and Latin American (LATAM) regions. "The first sighting of its activity was in the second quarter of 2023; back then, it was predominantly observed in the APAC region," Trend Micro researchers Lenart Bermejo, Ted Lee, and Theo Chen said in a technical report published Monday. "Around the middle of 2024, it was also spotted in Latin America." The primary targets of the adversarial collective span countries such as Thailand, the Philippines, Malaysia, Taiwan, and Brazil. The infection chains begin with the exploitation of vulnerable services in internet-exposed web applications, using them to drop the Godzilla web shell for facilitating the deployment of additional payloads, including backdoors dubbed VA...

Entities in Ukraine have been targeted as part of a phishing campaign designed to distribute a remote access trojan called Remcos RAT . "The file names use Russian words related to the movement of troops in Ukraine as a lure," Cisco Talos researcher Guilherme Venere said in a report published last week. "The PowerShell downloader contacts geo-fenced servers located in Russia and Germany to download the second stage ZIP file containing the Remcos backdoor." The activity has been attributed with moderate confidence to a Russian hacking group known as Gamaredon , which is also tracked under the monikers Aqua Blizzard, Armageddon, Blue Otso, BlueAlpha, Hive0051, Iron Tilden, Primitive Bear, Shuckworm, Trident Ursa, UAC-0010, UNC530, and Winterflounder.  The threat actor, assessed to be affiliated with Russia's Federal Security Service (FSB), is known for its targeting of Ukrainian organizations for espionage and data theft. It's operational since at least ...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has shed light on a new malware called RESURGE that has been deployed as part of exploitation activity targeting a now-patched security flaw in Ivanti Connect Secure (ICS) appliances. "RESURGE contains capabilities of the SPAWNCHIMERA malware variant, including surviving reboots; however, RESURGE contains distinctive commands that alter its behavior," the agency said . "The file contains capabilities of a rootkit, dropper, backdoor, bootkit, proxy, and tunneler." The security issue associated with the deployment of the malware is CVE-2025-0282 , a stack-based buffer overflow vulnerability affecting Ivanti Connect Secure, Policy Secure, and ZTA Gateways that could result in remote code execution. It impacts the following versions - Ivanti Connect Secure before version 22.7R2.5 Ivanti Policy Secure before version 22.7R1.2, and  Ivanti Neurons for ZTA gateways before version 22.7R2.3 According...

An advanced persistent threat (APT) group with ties to Pakistan has been attributed to the creation of a fake website masquerading as India's public sector postal system as part of a campaign designed to infect both Windows and Android users in the country. Cybersecurity company CYFIRMA has attributed the campaign with medium confidence to a threat actor called APT36 , which is also known as Transparent Tribe.  The fraudulent website mimicking India Post is named "postindia[.]site." Users who land on the site from Windows systems are prompted to download a PDF document, whereas those visiting from an Android device are served a malicious application package ("indiapost.apk") file. "When accessed from a desktop, the site delivers a malicious PDF file containing ' ClickFix ' tactics," CYFIRMA said . "The document instructs users to press the Win + R keys, paste a provided PowerShell command into the Run dialog, and execute it – potentia...
