Threat actors are weaponizing exposed Java Debug Wire Protocol ( JDWP ) interfaces to obtain code execution capabilities and deploy cryptocurrency miners on compromised hosts. "The attacker used a modified version of XMRig with a hard-"coded configuration, allowing them to avoid suspicious command-line arguments that are often flagged by defenders," Wiz researchers Yaara Shriki and Gili Tikochinski said in a report published this week. "The payload used mining pool proxies to hide their cryptocurrency wallet address, thereby preventing investigators from pivoting on it." The cloud security firm, which is being acquired by Google Cloud, said it observed the activity against its honeypot servers running TeamCity, a popular continuous integration and continuous delivery (CI/CD) tool. JDWP is a communication protocol used in Java for debugging purposes. With JDWP, users can leverage a debugger to work in a different process, a Java application, on the same com...

A mobile ad fraud operation dubbed IconAds that consisted of 352 Android apps has been disrupted, according to a new report from HUMAN. The identified apps were designed to load out-of-context ads on a user's screen and hide their icons from the device home screen launcher, making it harder for victims to remove them, per the company's Satori Threat Intelligence and Research Team. The apps have since been removed from the Play Store by Google. The ad fraud scheme accounted for 1.2 billion bid requests a day, at the height of its activity. The vast majority of IconAds-associated traffic originated from Brazil, Mexico, and the United States. It's worth noting that IconAds is a variant of a threat that's also tracked by other cybersecurity vendors under the names HiddenAds and Vapor , with the malicious apps repeatedly slipping past the Google Play Store since at least 2019 . Some of the common characteristics of these apps include the use of obfuscation to conceal...

Cybersecurity researchers have uncovered over 40 malicious browser extensions for Mozilla Firefox that are designed to steal cryptocurrency wallet secrets, putting users' digital assets at risk. "These extensions impersonate legitimate wallet tools from widely-used platforms such as Coinbase, MetaMask, Trust Wallet, Phantom, Exodus, OKX, Keplr, MyMonero, Bitget, Leap, Ethereum Wallet, and Filfox," Koi Security researcher Yuval Ronen said . The large-scale campaign is said to have been ongoing since at least April 2025, with new extensions uploaded to the Firefox Add-ons store as recently as last week. The identified extensions have been found to artificially inflate their popularity, adding hundreds of 5-star reviews that go far beyond the total number of active installations. This strategy is employed to give them an illusion of authenticity, making it seem like they are widely adopted and tricking unsuspecting users into installing them. Another tactic adopted by ...

SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...

The French cybersecurity agency on Tuesday revealed that a number of entities spanning governmental, telecommunications, media, finance, and transport sectors in the country were impacted by a malicious campaign undertaken by a Chinese hacking group by weaponizing several zero-day vulnerabilities in Ivanti Cloud Services Appliance (CSA) devices. The campaign, detected at the beginning of September 2024, has been attributed to a distinct intrusion set codenamed Houken , which is assessed to share some level overlaps with a threat cluster tracked by Google Mandiant under the moniker UNC5174 (aka Uteus or Uetus). "While its operators use zero-day vulnerabilities and a sophisticated rootkit, they also leverage a wide number of open-source tools mostly crafted by Chinese-speaking developers," the French National Agency for the Security of Information Systems (ANSSI) said . "Houken's attack infrastructure is made up of diverse elements -- including commercial VPNs and d...

Threat actors with ties to North Korea have been observed targeting Web3 and cryptocurrency-related businesses with malware written in the Nim programming language, underscoring a constant evolution of their tactics. "Unusually for macOS malware, the threat actors employ a process injection technique and remote communications via wss, the TLS-encrypted version of the WebSocket protocol," SentinelOne researchers Phil Stokes and Raffaele Sabato said in a report shared with The Hacker News. "A novel persistence mechanism takes advantage of SIGINT/SIGTERM signal handlers to install persistence when the malware is terminated or the system rebooted." The cybersecurity company is tracking the malware components collectively under the name NimDoor. It's worth noting that some aspects of the campaign were previously documented by Huntabil.IT and later by Huntress and Validin , but with differences in the payloads deployed. The attack chains involve social enginee...

Cybersecurity researchers are calling attention to phishing campaigns that impersonate popular brands and trick targets into calling phone numbers operated by threat actors. "A significant portion of email threats with PDF payloads persuade victims to call adversary-controlled phone numbers, displaying another popular social engineering technique known as Telephone-Oriented Attack Delivery (TOAD), also known as callback phishing," Cisco Talos researcher Omid Mirzaei said in a report shared with The Hacker News. An analysis of phishing emails with PDF attachments between May 5 and June 5, 2025, has revealed Microsoft and Docusign to be the most impersonated brands. NortonLifeLock, PayPal, and Geek Squad are among the most impersonated brands in TOAD emails with PDF attachments. The activity is part of wider phishing attacks that attempt to leverage the trust people have with popular brands to initiate malicious actions. These messages typically incorporate PDF attachments...

The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) has levied sanctions against Russia-based bulletproof hosting (BPH) service provider Aeza Group to assist threat actors in their malicious activities and targeting victims in the country and across the world. The sanctions also extend to its subsidiaries Aeza International Ltd., the U.K. branch of Aeza Group, as well as Aeza Logistic LLC, Cloud Solutions LLC, and four individuals linked to the company - Arsenii Aleksandrovich Penzev, CEO and 33% owner of Aeza Group Yurii Meruzhanovich Bozoyan, general director and 33% owner of Aeza Group Vladimir Vyacheslavovich Gast, technical director who works closely with Penzev and Bozoyan Igor Anatolyevich Knyazev, 33% owner of Aeza Group who manages the operations in the absence of Penzev and Bozoyan It's worth noting that Penzev was arrested in early April 2025 on charges of leading a criminal organization and enabling large-scale drug trafficking ...

Unknown threat actors have been observed weaponizing v0 , a generative artificial intelligence (AI) tool from Vercel, to design fake sign-in pages that impersonate their legitimate counterparts. "This observation signals a new evolution in the weaponization of Generative AI by threat actors who have demonstrated an ability to generate a functional phishing site from simple text prompts," Okta Threat Intelligence researchers Houssem Eddine Bordjiba and Paula De la Hoz said . v0 is an AI-powered offering from Vercel that allows users to create basic landing pages and full-stack apps using natural language prompts. The identity services provider said it has observed scammers using the technology to develop convincing replicas of login pages associated with multiple brands, including an unnamed customer of its own. Following responsible disclosure, Vercel has blocked access to these phishing sites. The threat actors behind the campaign have also been found to host other ...

Cybersecurity researchers have flagged the tactical similarities between the threat actors behind the RomCom RAT and a cluster that has been observed delivering a loader dubbed TransferLoader . Enterprise security firm Proofpoint is tracking the activity associated with TransferLoader to a group dubbed UNK_GreenSec and the RomCom RAT actors under the moniker TA829 . The latter is also known by the names CIGAR, Nebulous Mantis, Storm-0978, Tropical Scorpius, UAC-0180, UAT-5647, UNC2596, and Void Rabisu. The company said it discovered UNK_GreenSec as part of its investigation into TA829, describing it as using an "unusual amount of similar infrastructure, delivery tactics, landing pages, and email lure themes." TA829 is something of an unusual hacking group in the threat landscape given its ability to conduct both espionage as well as financially motivated attacks. The Russia-aligned hybrid group has also been linked to the zero-day exploitation of security flaws in Mozil...

The threat actor known as Blind Eagle has been attributed with high confidence to the use of the Russian bulletproof hosting service Proton66 . Trustwave SpiderLabs, in a report published last week, said it was able to make this connection by pivoting from Proton66-linked digital assets, leading to the discovery of an active threat cluster that leverages Visual Basic Script (VBS) files as its initial attack vector and installs off-the-shelf remote access trojans (RATS). Many threat actors rely on bulletpro While Visual Basic Script (VBS) might seem outdated, it's still a of hosting providers like Proton66 because these services intentionally ignore abuse reports and legal takedown requests. This makes it easier for attackers to run phishing sites, command-and-control servers, and malware delivery systems without interruption. The cybersecurity company said it identified a set of domains with a similar naming pattern (e.g., gfast.duckdns[.]org, njfast.duckdns[.]org) beginning i...

Ever wonder what happens when attackers don't break the rules—they just follow them better than we do? When systems work exactly as they're built to, but that "by design" behavior quietly opens the door to risk? This week brings stories that make you stop and rethink what's truly under control. It's not always about a broken firewall or missed patch—it's about the small choices, default settings, and shortcuts that feel harmless until they're not. The real surprise? Sometimes the threat doesn't come from outside—it's baked right into how things are set up. Dive in to see what's quietly shaping today's security challenges. ⚡ Threat of the Week FBI Warns of Scattered Spider's on Airlines — The U.S. Federal Bureau of Investigation (FBI) has warned of a new set of attacks mounted by the notorious cybercrime group Scattered Spider targeting the airline sector using sophisticated social engineering techniques to obtain initial access. Cybersecurity vendors Palo Alto Networks Unit 4...

The threat actor behind the GIFTEDCROOK malware has made significant updates to turn the malicious program from a basic browser data stealer to a potent intelligence-gathering tool. "Recent campaigns in June 2025 demonstrate GIFTEDCROOK's enhanced ability to exfiltrate a broad range of sensitive documents from the devices of targeted individuals, including potentially proprietary files and browser secrets," Arctic Wolf Labs said in a report published this week. "This shift in functionality, combined with the content of its phishing lures, [...] suggests a strategic focus on intelligence gathering from Ukrainian governmental and military entities." GIFTEDCROOK was first documented by the Computer Emergency Response Team of Ukraine (CERT-UA) in early April 2025 in connection with a campaign targeting military entities, law enforcement agencies, and local self-government bodies. The activity, attributed to a hacking group it tracks as UAC-0226, involves th...

Threat hunters have discovered a network of more than 1,000 compromised small office and home office (SOHO) devices that have been used to facilitate a prolonged cyber espionage infrastructure campaign for China-nexus hacking groups. The Operational Relay Box (ORB) network has been codenamed LapDogs by SecurityScorecard's STRIKE team. "The LapDogs network has a high concentration of victims across the United States and Southeast Asia, and is slowly but steadily growing in size," the cybersecurity company said in a technical report published this week. Other regions where the infections are prevalent include Japan, South Korea, Hong Kong, and Taiwan, with victims spanning IT, networking, real estate, and media sectors. Active infections span devices and services from Ruckus Wireless, ASUS, Buffalo Technology, Cisco-Linksys, Cross DVR, D-Link, Microsoft, Panasonic, and Synology.  LapDogs' beating heart is a custom backdoor called ShortLeash that's engineered...

A China-linked threat actor known as Mustang Panda has been attributed to a new cyber espionage campaign directed against the Tibetan community. The spear-phishing attacks leveraged topics related to Tibet, such as the 9th World Parliamentarians' Convention on Tibet (WPCT), China's education policy in the Tibet Autonomous Region (TAR), and a recently published book by the 14th Dalai Lama, according to IBM X-Force. The cybersecurity division of the technology company said it observed the campaign earlier this month, with the attacks leading to the deployment of a known Mustang Panda malware called PUBLOAD . It's tracking the threat actor under the name Hive0154. The attack chains employ Tibet-themed lures to distribute a malicious archive containing a benign Microsoft Word file, along with articles reproduced by Tibetan websites and photos from WPCT, into opening an executable that's disguised as a document. The executable, as observed in prior Mustang Panda atta...

A new campaign has been observed leveraging fake websites advertising popular software such as WPS Office, Sogou, and DeepSeek to deliver Sainbox RAT and the open-source Hidden rootkit. The activity has been attributed with medium confidence to a Chinese hacking group called Silver Fox (aka Void Arachne), citing similarities in tradecraft with previous campaigns attributed to the threat actor. The phishing websites ("wpsice[.]com") have been found to distribute malicious MSI installers in the Chinese language, indicating that the targets of the campaign are Chinese speakers. "The malware payloads include the Sainbox RAT, a variant of Gh0st RAT, and a variant of the open-source Hidden rootkit," Netskope Threat Labs researcher Leandro Fróes said . This is not the first time the threat actor has resorted to this modus operandi. In July 2024, eSentire detailed a campaign that targeted Chinese-speaking Windows users with fake Google Chrome sites to deliver Gh0st...

Threat intelligence firm GreyNoise is warning of a "notable surge" in scanning activity targeting Progress MOVEit Transfer systems starting May 27, 2025—suggesting that attackers may be preparing for another mass exploitation campaign or probing for unpatched systems. MOVEit Transfer is a popular managed file transfer solution used by businesses and government agencies to share sensitive data securely. Because it often handles high-value information, it has become a favorite target for attackers.  "Prior to this date, scanning was minimal — typically fewer than 10 IPs observed per day," the company said . "But on May 27, that number spiked to over 100 unique IPs, followed by 319 IPs on May 28." Since then, daily scanner IP volume has remained intermittently elevated between 200 to 300 IPs per day, GreyNoise added, stating it marks a "significant deviation" from usual behavior. As many as 682 unique IPs have been flagged in connection with th...

Cybersecurity researchers have detailed a new campaign dubbed OneClik that leverages Microsoft's ClickOnce software deployment technology and bespoke Golang backdoors to compromise organizations within the energy, oil, and gas sectors. "The campaign exhibits characteristics aligned with Chinese-affiliated threat actors, though attribution remains cautious," Trellix researchers Nico Paulo Yturriaga and Pham Duy Phuc said in a technical write-up. "Its methods reflect a broader shift toward 'living-off-the-land' tactics, blending malicious operations within cloud and enterprise tooling to evade traditional detection mechanisms." The phishing attacks, in a nutshell, make use of a .NET-based loader called OneClikNet to deploy a sophisticated Go-based backdoor codenamed RunnerBeacon that's designed to communicate with attacker-controlled infrastructure that's obscured using Amazon Web Services (AWS) cloud services. ClickOnce is offered by Micro...
