⚡ Weekly Recap — SharePoint Breach, Spyware, IoT Hijacks, DPRK Fraud, Crypto Drains and More

⚡ Weekly Recap — SharePoint Breach, Spyware, IoT Hijacks, DPRK Fraud, Crypto Drains and More

Jul 28, 2025
Some risks don't breach the perimeter—they arrive through signed software, clean resumes, or sanctioned vendors still hiding in plain sight. This week, the clearest threats weren't the loudest—they were the most legitimate-looking. In an environment where identity, trust, and tooling are all interlinked, the strongest attack path is often the one that looks like it belongs. Security teams are now challenged to defend systems not just from intrusions—but from trust itself being turned into a weapon. ⚡ Threat of the Week Microsoft SharePoint Attacks Traced to China — The fallout from an attack spree targeting defects in on-premises Microsoft SharePoint servers continues to spread a week after the discovery of the zero-day exploits, with more than 400 organizations globally compromised. The attacks have been attributed to two known Chinese hacking groups tracked as Linen Typhoon (aka APT27), Violet Typhoon (aka APT31), and a suspected China-based threat actor codenamed Storm-2603 t...
Email Security Is Stuck in the Antivirus Era: Why It Needs a Modern Approach

Email Security Is Stuck in the Antivirus Era: Why It Needs a Modern Approach

Jul 28, 2025 Email Security / Cloud Security
Picture this: you've hardened every laptop in your fleet with real‑time telemetry, rapid isolation, and automated rollback. But the corporate mailbox—the front door for most attackers—is still guarded by what is effectively a 1990s-era filter. This isn't a balanced approach. Email remains a primary vector for breaches, yet we often treat it as a static stream of messages instead of a dynamic, post-delivery environment. This environment is rich with OAuth tokens, shared drive links, and years of sensitive data. The conversation needs to shift. We should stop asking, "Did the gateway block the bad thing?" and start asking, "How quickly can we see, contain, and undo the damage when an attacker inevitably gets in?" Looking at email security through this lens forces a fundamental shift toward the same assume-breach, detect-and-respond mindset that already revolutionized endpoint protection. The day the wall crumbled Most security professionals know the statisti...
Scattered Spider Hijacks VMware ESXi to Deploy Ransomware on Critical U.S. Infrastructure

Scattered Spider Hijacks VMware ESXi to Deploy Ransomware on Critical U.S. Infrastructure

Jul 28, 2025 Cyber Attack / Ransomware
The notorious cybercrime group known as Scattered Spider is targeting VMware ESXi hypervisors in attacks targeting retail, airline, and transportation sectors in North America. "The group's core tactics have remained consistent and do not rely on software exploits. Instead, they use a proven playbook centered on phone calls to an IT help desk," Google's Mandiant team said in an extensive analysis. "The actors are aggressive, creative, and particularly skilled at using social engineering to bypass even mature security programs. Their attacks are not opportunistic but are precise, campaign-driven operations aimed at an organization's most critical systems and data." Also called 0ktapus, Muddled Libra, Octo Tempest, and UNC3944, the threat actors have a history of conducting advanced social engineering attacks to obtain initial access to victim environments and then adopting a "living-off-the-land" (LotL) approach by manipulating trusted ad...

Critical Flaws in Niagara Framework Threaten Smart Buildings and Industrial Systems Worldwide

Critical Flaws in Niagara Framework Threaten Smart Buildings and Industrial Systems Worldwide

Jul 28, 2025 Vulnerability / Critical Infrastructure
Cybersecurity researchers have discovered over a dozen security vulnerabilities impacting Tridium's Niagara Framework that could allow an attacker on the same network to compromise the system under certain circumstances. "These vulnerabilities are fully exploitable if a Niagara system is misconfigured, thereby disabling encryption on a specific network device," Nozomi Networks Labs said in a report published last week. "If chained together, they could allow an attacker with access to the same network — such as through a Man-in-the-Middle (MiTM) position — to compromise the Niagara system." Developed by Tridium, an independent business entity of Honeywell, the Niagara Framework is a vendor-neutral platform used to manage and control a wide range of devices from different manufacturers, such as HVAC, lighting, energy management, and security, making it a valuable solution in building management, industrial automation, and smart infrastructure environments.

U.S. Sanctions Firm Behind N. Korean IT Scheme; Arizona Woman Jailed for Running Laptop Farm

U.S. Sanctions Firm Behind N. Korean IT Scheme; Arizona Woman Jailed for Running Laptop Farm

Jul 25, 2025 Cybercrime / Insider Threat
The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) sanctioned a North Korean front company and three associated individuals for their involvement in the fraudulent remote information technology (IT) worker scheme designed to generate illicit revenues for Pyongyang. The sanctions target Korea Sobaeksu Trading Company (aka Sobaeksu United Corporation), and Kim Se Un, Jo Kyong Hun, and Myong Chol Min for evading sanctions imposed by the U.S. and the United Nations against the Democratic People's Republic of Korea (DPRK) government.  "Our commitment is clear: Treasury, as part of a whole-of-government effort, will continue to hold accountable those who seek to infiltrate global supply chains and enable the sanctions evasion activities that further the Kim regime's destabilizing agenda," said Director of OFAC Bradley T. Smith. The latest action marks the U.S. government's continued efforts to dismantle North Korea's wide-ranging r...
Patchwork Targets Turkish Defense Firms with Spear-Phishing Using Malicious LNK Files

Patchwork Targets Turkish Defense Firms with Spear-Phishing Using Malicious LNK Files

Jul 25, 2025 Malware / Threat Intelligence
The threat actor known as Patchwork has been attributed to a new spear-phishing campaign targeting Turkish defense contractors with the goal of gathering strategic intelligence. "The campaign employs a five-stage execution chain delivered via malicious LNK files disguised as conference invitations sent to targets interested in learning more about unmanned vehicle systems," Arctic Wolf Labs said in a technical report published this week. The activity, which also singled out an unnamed manufacturer of precision-guided missile systems, appears to be geopolitically motivated as the timing coincides amid deepening defense cooperation between Pakistan and Türkiye, and the recent India-Pakistan military skirmishes. Patchwork, also called APT-C-09, APT-Q-36, Chinastrats, Dropping Elephant, Operation Hangover, Quilted Tiger, and Zinc Emerson, is assessed to be a state-sponsored actor of Indian origin. Known to be active since at least 2009, the hacking group has a track record ...
Cyber Espionage Campaign Hits Russian Aerospace Sector Using EAGLET Backdoor

Cyber Espionage Campaign Hits Russian Aerospace Sector Using EAGLET Backdoor

Jul 25, 2025 Cyber Espionage / Malware
Russian aerospace and defense industries have become the target of a cyber espionage campaign that delivers a backdoor called EAGLET to facilitate data exfiltration. The activity, dubbed Operation CargoTalon , has been assigned to a threat cluster tracked as UNG0901 (short for Unknown Group 901). "The campaign is aimed at targeting employees of Voronezh Aircraft Production Association (VASO), one of the major aircraft production entities in Russia via using товарно-транспортная накладная (TTN) documents — critical to Russian logistics operations," Seqrite Labs researcher Subhajeet Singha said in an analysis published this week. The attack commences with a spear-phishing email bearing cargo delivery-themed lures that contain a ZIP archive, within which is a Windows shortcut (LNK) file that uses PowerShell to display a decoy Microsoft Excel document, while also deploying the EAGLET DLL implant on the host. The decoy document, per Seqrite, references Obltransterminal, a ...
Soco404 and Koske Malware Target Cloud Services with Cross-Platform Cryptomining Attacks

Soco404 and Koske Malware Target Cloud Services with Cross-Platform Cryptomining Attacks

Jul 25, 2025 Malware / Cloud Security
Threat hunters have disclosed two different malware campaigns that have targeted vulnerabilities and misconfigurations across cloud environments to deliver cryptocurrency miners. The threat activity clusters have been codenamed Soco404 and Koske by cloud security firms Wiz and Aqua, respectively. Soco404 "targets both Linux and Windows systems, deploying platform-specific malware," Wiz researchers Maor Dokhanian, Shahar Dorfman, and Avigayil Mechtinger said . "They use process masquerading to disguise malicious activity as legitimate system processes." The activity is a reference to the fact that payloads are embedded in fake 404 HTML pages hosted on websites built using Google Sites. The bogus sites have since been taken down by Google. Wiz posited that the campaign, which has been previously observed going after Apache Tomcat services with weak credentials, as well as susceptible Apache Struts and Atlassian Confluence servers using the Sysrv botnet, is p...
Overcoming Risks from Chinese GenAI Tool Usage

Overcoming Risks from Chinese GenAI Tool Usage

Jul 25, 2025 Artificial Intelligence / Data Privacy
A recent analysis of enterprise data suggests that generative AI tools developed in China are being used extensively by employees in the US and UK, often without oversight or approval from security teams. The study, conducted by Harmonic Security, also identifies hundreds of instances in which sensitive data was uploaded to platforms hosted in China, raising concerns over compliance, data residency, and commercial confidentiality. Over a 30-day period, Harmonic examined the activity of a sample of 14,000 employees across a range of companies. Nearly 8 percent were found to have used China-based GenAI tools, including DeepSeek, Kimi Moonshot, Baidu Chat, Qwen (from Alibaba), and Manus. These applications, while powerful and easy to access, typically provide little information on how uploaded data is handled, stored, or reused. The findings underline a widening gap between AI adoption and governance, especially in developer-heavy organizations where time-to-output often trumps policy ...

CastleLoader Malware Infects 469 Devices Using Fake GitHub Repos and ClickFix Phishing

Jul 24, 2025 Malware / Cybercrime
Cybersecurity researchers have shed light on a new versatile malware loader called CastleLoader that has been put to use in campaigns distributing various information stealers and remote access trojans (RATs). The activity employs Cloudflare-themed ClickFix phishing attacks and fake GitHub repositories opened under the names of legitimate applications, Swiss cybersecurity company PRODAFT said in a report shared with The Hacker News. The malware loader, first observed in the wild earlier this year, has been used to distribute DeerStealer , RedLine , StealC , NetSupport RAT , SectopRAT , and even other loaders like Hijack Loader . "It employs dead code injection and packing techniques to hinder analysis," the company said. "After unpacking itself at runtime, it connects to a C2 (command-and-control) server, downloads target modules, and executes them." CastleLoader's modular structure allows it to act as both a delivery mechanism and a staging utility, enabling...
