Cybersecurity researchers have disclosed details of three cyber attacks targeting organizations in Japan in which artificial intelligence (AI) was a key element, either in the driving seat or to assist a human operator. TrendAI, which analyzed three exposed server environments used by threat actors to conduct the malicious cyber operations, described them as distinct from previously published attacks that have leveraged ARTEX , an autonomous AI penetration testing framework, to single out entities in South Korea and Japan. "These environments held reconnaissance and attack tools, scripts, target lists, results, logs, and command histories," security researchers Bakuei Matsukawa and Joseph C Chen said. "They ranged from workspaces used largely by hand by skilled operators to AI-agent platforms that automated the entire workflow, including command and control." The first of the three attacks has been found to abuse CyberStrikeAI , another open-source penetra...

The North Korea-linked Lazarus Group has been attributed to a cyber espionage campaign dubbed Operation FlashHole targeting at least three organizations in South Korea spanning the construction, software, and wire-communication equipment manufacturing sectors. According to Russian cybersecurity company Kaspersky, the campaign has been active since at least July 2025. It's assessed to pick up from where Operation SyncHole left off. "The group targeted victims more selectively, sending spear‑phishing emails with links to fabricated but relevant sites, such as portfolio and résumé pages tailored to each target," Sojun Ryu, senior security researcher at Kaspersky GReAT, said in an exhaustive analysis. Operation SyncHole was first documented by Kaspersky in April 2025, detailing the state-sponsored adversary's targeting of South Korea's software, IT, financial, semiconductor manufacturing, and telecommunications industries since November 2024 to deliver malwa...

The Computer Emergency Response Team of Ukraine (CERT-UA) has issued an alert warning of unauthorized remote access to video surveillance systems manufactured by Dahua. "Cases of compromising IP cameras and DVRs with access to the video stream, changing the device configuration and creating third-party accounts have been recorded," the State Special Communications Service of Ukraine (SSSCIP) said in an alert issued last week. The primary initial access vector used in the attacks is via Easy4IP , a peer-to-peer (P2P) platform that allows users to remotely monitor homes or small businesses by connecting their Dahua IP cameras, NVRs, and DVRs via a smartphone app or web browser by scanning a QR code or entering the hardware Serial Number (SN). The agency has warned that the serial numbers have a predictable structure containing a 10-character model prefix that's identical for all units of the same device family and a five-character hexadecimal counter that's i...

A rentable Android spyware kit called uCreator takes over Telegram and WeChat accounts by hiding its code inside working copies of the two apps, researcher Ovi found . It only reaches people who install one of these tampered copies, spread outside the official app stores, or who run WeChat inside the kit makers' own container app. The kit's Telegram part matches Baohuo , a backdoor that Doctor Web reported in October 2025 . Doctor Web found Baohuo in tampered copies of Telegram X, an Android app from Telegram. At the time, the company estimated that more than 58,000 devices were infected. The Hacker News compared the two reports. Doctor Web's technical description of Baohuo lists the same code namespace, com.ucreator.tgjar , the same command-and-control (C2) server, and matching command names as Ovi's analysis. Ovi's analysis, published October 21, 2026, does not mention Doctor Web's findings, and Doctor Web did not name the kit. It is not clear whether...

In an update, Palo Alto Networks Unit 42 said it's retracting its earlier assessment that the post-compromise activity targeting the European government agency involved the exploitation of the PHP2Shell flaws. "What researchers saw was an attack against a European government agency executed in the context of a vulnerable PHP application," a spokesperson for the company told The Hacker News via email. "This led us to believe that it was exploitation of those vulnerabilities. We are unable to confirm that initial access is associated with the specific PHP2Shell CVEs." The original story follows. Threat actors have been observed using agentic artificial intelligence (AI) platforms for post-exploitation activity following the abuse of the PHP2Shell vulnerabilities tracked as CVE-2026-109618 and CVE-2026-109619. "In one case, the attackers targeted a government entity in Europe and within two hours of the initial exploitation they had successfully acce...

Diplomatic organizations in Central Asia have been targeted by a sophisticated new Unified Extensible Firmware Interface (UEFI) bootkit called BlackX . The activity, which singled out diplomatic entities in Tajikistan, Uzbekistan, and Turkmenistan in early 2026, is suspected to be orchestrated by a China-linked state-sponsored hacking group known as APT41 , Kaspersky said in a technical report published this week. The primary objective behind deploying the malware is to undermine Microsoft Windows startup defenses, along with third-party security solutions, while maintaining long-term, covert access to compromised devices. Notably, BlackX is assessed to be an updated version of BlackLotus , a notorious bootkit that was first observed being advertised on cybercrime forums in late 2022, before its existence was officially confirmed by ESET in March 2023. BlackLotus is designed to exploit a now-patched Secure Boot bypass vulnerability tracked as CVE-2022-21894 (CVSS score: 4.4...

The Russian state-sponsored hacking group Sandworm teamed up with another threat actor to carry out a destructive wiping attack targeting a Ukrainian logistics company last year. According to ESET , the attack involved UAC-0099 (aka Earth Sirrush) obtaining initial access to the target on July 16, 2025, via a spear-phishing email bearing a malware-laced attachment that led to the deployment of the MATCHWOK backdoor through a downloader called MATCHBOIL. The activity ultimately concluded with the threat actor handing off access to Sandworm, which then conducted a data-wiping attack on September 17, 2025, more than two months after it obtained a foothold. What makes the attack stand out is UAC-0099's use of a previously undocumented backdoor called MythicRatatoskr that communicates with a command-and-control (C2) server hosted inside the Yggdrasil mesh network. The backdoor was deployed a day after MATCHWOK was executed. There are indications that development on the back...

Microsoft on Wednesday disclosed that a China state-aligned actor dubbed Storm-0940 was behind the recent supply chain compromise of the ConnectWise Cloud Backup application. During the incident, Storm-0940 used ARTEX , a Go-based agentic AI penetration testing framework that was made closed-source in the wake of its abuse in cyber attacks targeting South Korean financial institutions, to speed up scanning and reconnaissance, password spraying, and OAuth application abuse at downstream victims. The tech giant said the threat actor used the AI tool at "machine speed" to automate attacks targeting hundreds of organizations across the world spanning a broad range of sectors since September 2026. Targets include aerospace and defense, automotive, chemicals, energy, financial services, government, legal, manufacturing, media, military, semiconductor, software, technology, and think tanks and non-profits. "Storm-0940's use of ARTEX accelerated the speed of comprom...

Cybersecurity researchers have disclosed details of a previously undocumented China-aligned threat cluster known as Bronze Sandcastle that has been observed targeting organizations in Asia and Africa since mid-2025. "The most distinctive technical marker for Bronze Sandcastle is its consistent use of Sandboxie DLL sideloading," Sophos security researcher Gabor Szappanos said in a post published Tuesday. Between August 2025 and August 2026, attacks mounted by the threat actor have resulted in victims in the Philippines, Taiwan, Afghanistan, Namibia, and likely South Korea. Evidence indicates that Bronze Sandcastle is most active in the UTC+8 time zone.  DLL sideloading is a popular adversarial technique that exploits the way Windows loads DLL files, allowing an attacker to trick a legitimate program into loading a malicious DLL . When an application is launched, it needs to load various DLLs in order to function correctly. If the application does not provide the f...

Attackers took control of more than 300 Tor exit relays in early October and used them to redirect SSH connections to servers that stole login passwords, a researcher found. Exit relays are the last hop in a Tor circuit, where traffic leaves the network for its destination. Only a password login to an SSH server made through Tor between October 1 and 5, after accepting the interception server's host key, could have been captured. The Tor Project began flagging relays on October 4, and by October 5, none remained in the consensus, the list of relays that Tor clients use. At the peak on October 4, the relays carrying the attacker's exit policy made up 7.46% of Tor's exit capacity, measured by consensus weight, according to an  analysis of public Tor directory data  posted to the tor-relays mailing list. The researcher, who publishes as kaba,  scanned  all of Tor's roughly 3,000 exits on October 2 and found 333 redirecting SSH to the same 12 interception servers...

A Belarus-aligned hacktivist group spent nearly two years within the network of a Russian healthcare organization. According to a report published by Russian cybersecurity firm Solar, the activity has been attributed to a threat cluster dubbed Partisan Zmiy , which is also known as the Cyber Partisans . Known to be active since at least 2020, the group has a track record of striking industrial enterprises and government agencies in Russia and Belarus with a backdoor called Vasilek that uses Telegram for command-and-control (C2) and data exfiltration. Some of the attacks have also leveraged phishing lures to deliver an installer that simultaneously deploys the legitimate FortiClient VPN program on the system as well as an open-source program known as DNSCat2 that allows attackers to gain control of the infected host. A notable aspect of the threat actor is their ability to stage destructive attacks with a wiper referred to as Pryanik, alongside taking steps to systematical...

The iPhone of Vladan Đokić, rector of the University of Belgrade and a prominent supporter of Serbia's student protest movement, was infected with NSO Group's Pegasus spyware in 2026, the  Citizen Lab said  on October 19. The finding came six days before Serbia's October 25 snap parliamentary election. The infection used a zero-click exploit, meaning Đokić did not have to tap a link or open a file for it to work. The lab found the infection with high confidence, but its note provides no date within 2026, does not identify who was behind the attack, and notes that its investigation is ongoing. The election was  called in September  after nearly two years of protests that began when a railway station canopy collapsed in Novi Sad in November 2024, killing 16 people. The Citizen Lab, a research group at the University of Toronto, analyzed forensic artifacts from the phone at Đokić's request, working with the Serbian digital-rights group SHARE Foundation. SHARE ...

The Russia-linked state-sponsored threat actor tracked as APT28 (aka BlueDelta, Fancy Bear, and Forest Blizzard) has been attributed to attacks targeting two member states of the North Atlantic Treaty Organization (NATO). The Symantec Threat Hunter Team, which is tracking the activity cluster under the moniker Swallowtail , involved the use of a backdoor called HOOKEDGE and a previously undocumented loader that is designed to decrypt and run an encrypted payload in memory by using a cryptographic key that's supplied at runtime. Targets of the activity included a law enforcement agency, a naval shipbuilder, and a manufacturer of military aircraft engines – entities that hold information that could be of use to a foreign intelligence agency, the Broadcom-owned threat intelligence unit said. "During one attack against the naval shipbuilder, operators returned to a compromised host repeatedly over the course of a week in what appeared to be hands-on-keyboard activity,...

A U.S. court on Monday granted the U.S. government's request to detain a former OpenAI engineer accused of planting a recording device in an executive conference room at the company's San Francisco office to allegedly steal sensitive secrets. In a new court filing Sunday, prosecutors revealed that Abdulrahman Alfozan, a 35-year-old Saudi national, was "in frequent communications via WhatsApp with a member of the Saudi Royal Family" throughout 2025 and 2026. Alfozan is said to have communicated with the Saudi royal as recently as October 5, 2026, four days before he was arrested. "Among other things, the individual told the defendant that an artificial intelligence initiative was being launched in Saudi Arabia and wanted the defendant to join it," the filing reads. "In May 2026, the individual told the defendant, 'Saudi needs you more then [sic] the US!' to which the defendant responded '100,' indicating he agreed." The S...

The China-nexus cyber espionage group tracked as Armory Castle (previously UNC5221 or Warp Panda) exploited a newly disclosed security flaw in BeyondTrust Remote Support (formerly Bomgar) as a zero-day in late August 2026. The vulnerability, tracked as CVE-2026-102764 (CVSS score: 9.3), is a case of improper origin validation in an internal messaging component that could be exploited by a remote attacker to perform file operations on an affected appliance. "The vulnerability exists within internal components of Remote Support," BeyondTrust said in a Thursday alert. "The components did not adequately validate the origin of the messages it received. Under the right conditions, this could be used to perform file operations on the appliance." Patches for the flaw have been pushed to all Remote Support SaaS customers as of October 9, 2026. Self-hosted customers of Remote Support running versions from 24.3.1 through 26.2.3 are advised to manually update to BT26-0...

Candiru, an Israeli maker of spyware sold to governments, infected devices at the news network Al Jazeera through ordinary online ads, in attacks that needed no click or other action from the user, researchers at  the Citizen Lab  said Thursday. The hidden attack code ran the moment an ad loaded on the screen, and in some cases the ad loaded out of sight, in the background. The Citizen Lab, a research group at the University of Toronto, said this is the first public, technical confirmation that mercenary spyware, meaning hacking tools sold to governments, has reached real devices through targeted ads. The method had been described before from leaked company documents, but not shown in a live attack. The researchers recovered the spyware itself from one device, but not the exploit that breaks into the browser or app to install it. That first break-in step is described from how the attack was set up, not from captured code. How the Attack Worked The ads were placed by...

The threat actor known as Silent Lynx has been attributed to a fresh set of attacks targeting government organizations across the Commonwealth of Independent States (CIS). The activity, observed from June 2025 through August 2026, involves four different infection chains that make use of macro-enabled documents, PS2EXE downloaders, GitHub-hosted PowerShell, and crafted WinRAR archives exploiting CVE-2025-8088 . The attacks lead to the deployment of custom reverse shells like FoalShell, Chvost, Laplas, and PickleShell that facilitate interactive remote access to compromised hosts, according to Cisco Talos and Recorded Future Insikt Group, which are tracking the campaign under the monikers UAT-6275 and TAG-193.  "UAT-6275's targeting is concentrated in Central Asia, and the wider CIS region," security researcher Ashley Shen said . "Across the reviewed campaigns, observed victims and lure themes span nine countries: Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenist...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Thursday added five security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, following their abuse by a China-linked threat actor known as Flax Typhoon. The vulnerabilities in question are listed below - CVE-2015-3306 (CVSS score: 10.0) - An improper access control vulnerability in ProFTPD that could allow remote attackers to read and write to arbitrary files via the site cpfr and site cpto commands. CVE-2021-3199 (CVSS score: 9.8) - A path traversal vulnerability in ONLYOFFICE Docs that can occur when JSON Web Token (JWT) is used, via a "/.." sequence in an image upload parameter and could allow for remote code execution. CVE-2023-22894 (CVSS score: 7.2) - A cleartext storage of sensitive information vulnerability in Strapi that could allow an attacker with access to the admin panel to discover sensitive user details via the query filter. CVE-2016-3081 (CVSS score: 8.1) - A...

The U.S. Federal Bureau of Investigation (FBI) and Department of Justice (DoJ) have announced the disruption of malicious tools used by a China-linked advanced persistent threat group known as Flax Typhoon. To that end, the agencies seized several domains and blocked access to platforms that were used to scan, and in some cases infiltrate, U.S. critical infrastructure. The list of seized domains is as follows - c0cc[.]cc 98aiblog[.]com 98aicai[.]com 98aicode[.]com outlook3650[.]com youtubecard[.]com linkedinns[.]net Flax Typhoon , also tracked as Ethereal Panda and RedJuliett, is associated with Integrity Technology Group, a Beijing-based company that contracts with the Chinese government. It was previously attributed to a botnet called Raptor Train that comprised thousands of compromised small office/home office (SOHO) and IoT devices. It was taken down following a U.S. court-authorized operation in September 2024. "These state-sponsored hackers co...

Hackers tied to a Chinese cybersecurity company stole email from government organizations, law enforcement agencies, healthcare systems, and religious institutions in Southeast Asia, the FBI and agencies in 6 other countries said on October 8. The company, Integrity Technology Group , has been sanctioned by the U.S. and the UK. The hackers scanned websites for flaws using a tool containing more than 1,300 scripts, guessed passwords for Microsoft 365 and Exchange accounts, and copied mailboxes using tools designed to collect mail. The hackers have been breaking into networks since at least mid-January 2021, according to the agencies'  joint advisory . It describes the hacking in the present tense but provides no date for any theft and does not specify how many organizations were breached. The same hackers targeted U.S. government services, critical manufacturing, healthcare, and IT organizations, along with U.S. law enforcement, education, and religious groups. Organizations ...
