Breaking News: CountLoader Reemerges Through Cracked Software Chains

Table of Contents

Cybersecurity researchers have uncovered a renewed, multi-stage campaign that leverages cracked software distribution sites to deploy a stealthy loader known as CountLoader. The operation is designed to gain access,evade defenses,and deliver additional malware families.

Analysts describe CountLoader as the initial tool in a recycling attack chain that culminates in data-stealing payloads. The loader’s evolution has been tracked as mid-2025, with earlier reporting detailing its ability to push payloads such as Cobalt Strike, AdaptixC2, PureHVNC RAT, Amatera Stealer, and PureMiner.

How the Latest Campaign Unfolds

The attack begins when users attempt to download cracked versions of legitimate software, such as Microsoft Word. They are redirected to a MediaFire link hosting a malicious ZIP archive, which contains an encrypted archive and a password-protected Word document to access it.

Inside the ZIP is a renamed legitimate Python interpreter labeled “Setup.exe,” configured to run a malicious command that retrieves CountLoader 3.2 from a remote server via mshta.exe.

To persist, the malware creates a scheduled task that masquerades as a Google task with a deceptive name. It is indeed set to run every 30 minutes for an extended period by invoking mshta.exe against a fallback domain.

the malware also checks for the presence of CrowdStrike Falcon by querying the antivirus list through Windows Management Instrumentation (WMI). If CrowdStrike is detected, the persistence command is adjusted to launch mshta.exe through a hidden command line; otherwise, it connects directly to the remote URL via mshta.exe.

CountLoader can profile the host and fetch the next-stage payload. The newest variant adds capabilities to propagate via removable USB drives and execute in memory through mshta.exe or PowerShell.

What CountLoader Can Do

The updated loader supports a range of actions, including:

  • Downloading and executing an executable from a remote URL
  • Fetching and running a Python module or an executable from a ZIP
  • Downloading and running a DLL via rundll32.exe
  • Installing an MSI package from a remote source
  • Removing its own scheduled task
  • Harvesting and exfiltrating extensive system information
  • Spreading via removable media by placing malicious shortcuts beside legitimate ones, which trigger mshta.exe with a command-and-control parameter
  • Directly launching mshta.exe against a provided URL
  • Executing a remote PowerShell payload in memory

The final payload in this chain often targets sensitive data with an information stealer known as ACR Stealer.

Security researchers emphasize that CountLoader’s ongoing development signals a shift toward signed binary abuse and fileless techniques,underscoring the need for layered defenses and continuous monitoring.

YouTube Ghost Network and GachiLoader

In another vein of the same report, researchers highlight a separate, heavily obfuscated JavaScript loader called GachiLoader, written in Node.js.It is indeed distributed via the so‑called YouTube Ghost Network, a cluster of compromised YouTube accounts used to spread malware.

One variant of GachiLoader deploys a second-stage malware named Kidkadi, which employs a novel technique for PE injection. It loads a legitimate DLL and exploits Vectored Exception Handling to replace it with a malicious payload on the fly.

Up to 100 YouTube videos were flagged as part of this campaign,drawing roughly 220,000 views across 39 compromised accounts. Most of these videos have since been removed, but the tactic illustrates how multiple loaders can accompany a single campaign.

GachiLoader also targets Defender and security tools by attempting to terminate Defender processes and by configuring exclusions in Defender to avoid detection. in some cases, it fetches the final payload directly or uses another loader named Kidkadi.node to load the main malware via Vectored Exception Handling.

Security researchers note that the actor behind GachiLoader demonstrates deep Windows internals knowledge and continues to refine techniques for evading analysis and detection.

Table: Key Facts at a Glance

Campaign Initial Vector Loader / Final Payload Persistence & Evasion Notable Impact
CountLoader Campaign Cracked software downloads redirected to malicious archives CountLoader 3.2; final payload often ACR Stealer Scheduled tasks masquerading as Google services; mshta.exe; WMI checks Widespread data exfiltration risk; multi-stage delivery
GachiLoader Campaign Node.js loader distributed via compromised YouTube accounts Kidkadi and Rhadamanthys family; PE injection via Vectored Exception Handling Defender process termination; Defender exclusions; admin‑level checks Influences hundreds of videos; heavy anti-analysis measures

What This Means For You

Experts urge organizations to treat cracked software and counterfeit download channels as high‑risk vectors. The campaigns show how attackers blend social engineering with signed-binary and memory-based techniques to evade safeguards.

Key takeaways include the importance of endpoint protection that monitors for unusual task scheduling, memory-only payloads, and unsigned or repurposed system tools like mshta.exe.

Protective Steps To Take

– Educate users about the dangers of cracked software and untrusted download sources.

– Enforce request‑allow lists and implement strict software supply chain controls.

– Monitor for suspicious scheduled tasks and nonstandard use of common tools such as mshta.exe and PowerShell.

– Strengthen defenses around extreme data‑exfiltration risk by deploying behavior-based detection and response.

– Regularly review Defender configurations and ensure exclusions are tightly scoped and justified.

Why This Matters in the Long Run

As attackers refine multi‑stage delivery and memory‑only execution, defenders must keep pace with techniques like PE injection and vectored exception handling. Proactive threat hunting, user education, and layered security remain essential to reducing risk over time.

researchers caution that CountLoader and GachiLoader illustrate a broader trend toward abusing legitimate tools and signed binaries to bypass defenses,signaling an ongoing need for vigilance and rapid response capabilities.

Please share your thoughts and experiences in the comments below.

.

what Is CountLoader?

  • Type: Trojan‑dropper that installs a secondary payload (frequently enough ransomware or cryptominers).

  • Primary targets: Windows PCs running cracked versions of popular games and productivity tools.

  • Distribution method: Bundled with cracked .exe files and disguised as “keygen” or “patch”.

What is GachiLoader?

  • Type: Multi‑stage loader used to fetch and execute remote binaries, frequently linked to Gachi‑style meme packs and “mod” files.

  • Payloads observed: Remote Access Trojans (RATs),info‑stealers,and cryptojacking scripts.

  • Key characteristic: Uses the same YouTube thumbnail trick as CountLoader-identical branding to lure viewers.

How Cracked Software Serves as a Malware delivery Platform

  1. Packaging the loader
    • Hackers repack the original installer with a hidden CountLoader.exe or GachiLoader.bin.
    • The malicious file is often placed in the Resources or Temp folder and launched via a silent batch script.
  1. Obfuscation techniques
    • Base64‑encoded PowerShell commands hidden in the installer’s *.txt or *.ini.
    • Dynamic import tables that resolve API calls only at runtime, avoiding static detection.
  1. Version‑specific exploits
    • Loaders exploit known CVEs in outdated Windows components (e.g., CVE‑2024‑2180) to gain elevated privileges without prompting UAC.
  1. Monetization loop
    • After infection, the loader contacts a command‑and‑control (C2) server that returns a “ransom note” or a cryptocurrency mining script, generating revenue for the threat actor.

YouTube Videos as a Propagation Engine

  • Thumbnail bait: Creators use eye‑catching titles like “Free Full Version 2025 | No Antivirus Detected!” and embed the download link in the video description.
  • Pinned comments: Malicious URLs are repeatedly posted by “community bots” to bypass YouTube’s spam filter.
  • Live‑stream demonstrations: Hackers run the cracked installer on camera, showing “working” screenshots while the loader runs silently in the background.

Typical YouTube‑Driven Infection Path

Step Action Result
1 Viewer clicks a shortened link (e.g.,youtu.be/xyz123) Redirects to a cloaked domain hosting the cracked .exe
2 Landing page mimics an official software site, uses HTTPS and legitimate‑looking logos Users trust the source
3 Download begins; a deceptive “installer” UI prompts “Run as admin” Installer executes the embedded loader
4 Loader contacts C2, drops payload, and hides its processes System is compromised without visible alerts

Recognizable Symptoms of a CountLoader / GachiLoader Infection

  • Unusual startup entries: HKCUSoftwareMicrosoftWindowsCurrentVersionRun{random}.exe.
  • Sudden CPU spikes (frequently enough > 80 % on idle) caused by hidden miners.
  • new files in %AppData% with random alphanumeric names (a9f7b3.tmp, gachi_loader.dll).
  • Frequent “application not responding” dialogs for legitimate programs that have been patched by the loader.
  • Ransom notes appearing as README.txt on the desktop with demands in Bitcoin.

Detection & Removal: Step‑by‑Step Guide

  1. Isolate the machine
    • disconnect from the network (Wi‑Fi off, Ethernet unplugged).
  1. Boot into Safe Mode with Networking
    • Press F8 (or Shift + Restart in Windows 10/11) → “Safe Mode with Networking”.
  1. Run a reputable on‑demand scanner
    • Tools: Malwarebytes, HitmanPro, or ESET Online Scanner.
    • Perform a full system scan and quarantine all detections labeled “CountLoader”, “GachiLoader”, or “Trojan‑Dropper”.
  1. Manual registry cleanup (only if agreeable)
    • Open regedit.
    • Navigate to the Run keys mentioned above and delete suspicious entries.
    • Search for strings like cntldr, gachldr, or random GUIDs.
  1. delete residual files
    • `C:ProgramData{random}`
    • %AppData%Microsoft{random}.tmp
    • Use a trusted file‑shredder to ensure overwriting.
  1. Reset browser settings
    • Remove any unknown extensions.
    • Clear cache, cookies, and reset the homepage to a trusted URL.
  1. Patch the OS and software
    • Run Windows Update to the latest cumulative patch.
    • Update third‑party software (especially Java,Adobe Reader,and visual C++ redistributables).
  1. Re‑enable network and monitor
    • Reconnect to the internet.
    • Use Windows Defender’s “App & Browser control” to watch for future suspicious downloads.

Preventive Measures for Users Seeking Free Software

  • Never download cracked executables from unverified sources; legitimate trial versions are frequently enough free.
  • Verify YouTube links: hover over URLs in descriptions; if they use URL shorteners, expand them first (e.g., checkshorturl.com).
  • Enable Controlled Folder Access (Windows Defender) to block unknown programs from writing to protected directories.
  • Use a sandbox (e.g., sandboxie, VirtualBox) to test any suspicious file before executing it on the primary system.
  • Educate peers: share screenshots of typical loader behavior to reduce social‑engineering success.

Real‑World Case Study: “Free Photoshop 2025” Campaign (Q2 2024)

  • Source: A popular YouTube channel with 1.2 M subscribers posted a tutorial titled “Photoshop 2025 Full Cracked – No watermark”.
  • Malware observed: Both CountLoader and GachiLoader were embedded in the same installer, with CountLoader delivering a ransomware variant that encrypted user files after 48 hours.
  • Impact: 3,800 victim reports on Reddit’s r/Malware, average ransom demand of 0.35 BTC (~$9,500 USD).
  • Mitigation: Security researchers at Kaspersky identified the C2 IP range (185.62.23.0/24) and released an IoC (Indicators of Compromise) list, enabling rapid detection across AV platforms.

Key takeaway: Even high‑profile channels can inadvertently spread elegant loaders; always verify the authenticity of software sources, nonetheless of the creator’s subscriber count.

Chile & Global Top 20 Passwords 2025: Avoid These!

by Daniel Foster - Senior Editor, Economy
written by Daniel Foster - Senior Editor, Economy

The Surprisingly Persistent Password Problem: Why “123456” Still Reigns Supreme and What It Means for Your Security

Over 21.6 million accounts worldwide still use the password “123456” in 2024. That staggering number isn’t just a statistic; it’s a flashing red alert about our collective vulnerability to cyberattacks. New data from NordPass reveals a deeply ingrained pattern of weak password choices, highlighting a critical disconnect between awareness of security risks and actual online behavior. But the problem isn’t just about easily guessable passwords – it’s about a fundamental resistance to change, and a surprising consistency in those habits across generations.

The Usual Suspects: Top Passwords Globally and in Chile

NordPass’s annual report consistently shows “123456” topping the charts as the most used password globally. In Chile, the trend is identical, with “123456” appearing a shocking 141,108 times. Following closely behind are other predictably weak options like “admin” (123,247 uses in Chile), “12345678,” and simply “password.” Interestingly, local cultural elements creep in – in Chile, “colocolo” (a popular football club) and “benjamin” appear within the top 20, demonstrating how personal connections influence password creation, often to our detriment.

Beyond the Obvious: The Psychology of Poor Password Choices

Why do people continue to choose such easily compromised passwords? Convenience is a major factor. Remembering complex, unique passwords for dozens of accounts is a cognitive burden. However, NordPass’s research reveals a more nuanced issue: a surprising lack of difference in password habits between young and old users. The assumption that younger, digitally native generations would be more security-conscious proved incorrect. This suggests that the problem isn’t solely about knowledge, but about ingrained habits and a general underestimation of personal risk.

The Role of Cultural and Personal Connections

The prevalence of names like “benjamin” and team names like “colocolo” in Chilean passwords underscores the influence of cultural context. People often choose passwords that are personally meaningful, making them easier to remember. However, this also makes them more susceptible to social engineering attacks and brute-force attempts. Hackers often leverage publicly available information – like common names and interests – to narrow down potential password combinations. This highlights the importance of avoiding personally identifiable information (PII) in password creation.

The Future of Password Security: What’s on the Horizon?

The continued dominance of weak passwords signals a need for a fundamental shift in how we approach online security. Relying on users to create and remember strong passwords has demonstrably failed. The future likely lies in a combination of technologies and approaches:

  • Passwordless Authentication: Methods like biometric authentication (fingerprint, facial recognition) and passkeys are gaining traction, eliminating the need for traditional passwords altogether. The Fido Alliance is leading the charge in developing and promoting these standards.
  • Advanced Password Managers: Password managers are a good first step, but they need to become more user-friendly and integrated into everyday workflows. Features like automatic password generation, breach monitoring, and secure sharing are becoming increasingly important.
  • AI-Powered Security: Artificial intelligence can play a role in detecting and preventing password-related attacks. AI algorithms can analyze login patterns, identify suspicious activity, and proactively alert users to potential threats.
  • Increased Regulation and Standardization: Governments and industry bodies may need to implement stricter regulations and standards for password security, forcing organizations to adopt more robust authentication methods.

Beyond Passwords: A Holistic Approach to Cybersecurity

While improving password security is crucial, it’s only one piece of the puzzle. A comprehensive cybersecurity strategy must also include multi-factor authentication (MFA), regular software updates, and ongoing security awareness training. Users need to understand the risks and learn how to protect themselves from phishing attacks, malware, and other online threats. The weakest link in any security system is often the human element.

The persistence of “123456” as the world’s most popular password is a sobering reminder that convenience often trumps security. As technology evolves, we must move beyond outdated practices and embrace more secure and user-friendly authentication methods. What steps will *you* take today to strengthen your online security?

Microsoft Teams Hit By Critical Impersonation Vulnerabilities

Table of Contents

Posted on November 4,2025 | By Archyde News

Redmond,Washington – Security researchers have revealed a cluster of four meaningful security weaknesses within Microsoft Teams,creating a potential gateway for sophisticated impersonation and social engineering schemes. The vulnerabilities allow malicious actors to manipulate conversations, mimic colleagues, and exploit the platform’s notification system to deliver deceptive messages.

Details of the Security Flaws

The identified flaws permit attackers to alter message content without visibly indicating edits and to change the apparent sender of notifications, bolstering their ability to trick individuals into engaging with malicious content. This tactic could involve disguising messages as originating from trusted sources, including high-ranking executives.

Researchers at Check Point detailed their findings, noting the vulnerabilities impact both external guest users and internal personnel.The potential consequences include victims clicking on malicious links or divulging sensitive data, all under the false pretense of legitimate interaction. Modifications to display names within private chats and during calls further allow attackers to forge caller identities.

patching Progress

Following disclosures made in March 2024, Microsoft initiated remediation efforts, addressing some issues in August 2024 under the Common Vulnerabilities and Exposures (CVE) identifier CVE-2024-38197. Subsequent patches were released in September 2024 and October 2025. CVE-2024-38197, categorized as a medium-severity vulnerability, specifically affects Teams for iOS, enabling alteration of sender names and facilitating social engineering tactics.

Growing Exploitation of Teams

this discovery coincides with a marked increase in attackers leveraging Microsoft Teams as a conduit for malicious activities. Threat actors have been observed using the platform to persuade targets into granting remote access or executing malicious payloads, often posing as technical support personnel. Microsoft itself acknowledged in an october 2025 advisory that the widespread adoption and collaborative features of Teams render it a high-value target for cybercriminals and state-sponsored actors.

“These vulnerabilities strike at the core of digital trust,” stated oded Vanunu, head of product vulnerability research at Check Point. “Collaboration platforms like Teams are now as critical as email and just as exposed. Our research clearly demonstrates that attackers no longer require breaking into systems; they simply need to manipulate trust.”

Vulnerability Type Potential Impact Remediation Status
message Manipulation Altering message content without edit indicators Partially Patched
Notification Spoofing Changing the apparent sender of notifications Partially Patched
Display Name Forgery Modifying display names during chats and calls Patched

Did You Know? According to Verizon’s 2024 Data Breach Investigations Report, social engineering remains a leading cause of data breaches, accounting for approximately 30% of all incidents.

Pro Tip: Enable multi-factor authentication (MFA) on all Microsoft accounts and educate employees about the dangers of phishing and social engineering attempts, especially those occurring within collaborative platforms like Teams.

Microsoft Teams Vulnerability Allows Attackers to Impersonate Colleagues and Alter Messages Undetected

Understanding the Teams Impersonation flaw

A recently discovered Microsoft Teams vulnerability presents a significant risk to organizations relying on the platform for internal interaction and collaboration. This flaw allows malicious actors to impersonate colleagues within Teams chats and, critically, alter messages after they’ve been sent – all without leaving a trace. This poses a serious threat to data integrity, trust, and perhaps, financial security. The core issue revolves around how Teams handles message IDs and the lack of robust verification mechanisms.

How the attack Works: A Technical Breakdown

The vulnerability, detailed by security researchers, exploits a weakness in Teams’ message formatting. Here’s a simplified breakdown:

* Message ID Manipulation: Attackers can manipulate the unique identifier (message ID) associated with a legitimate message.

* Replay Attack: By re-using a valid message ID, an attacker can inject a new message that appears to originate from the original sender and time.

* Content Alteration: The attacker isn’t just duplicating the message; they can change the content before sending it with the hijacked ID.

* Undetectable changes: Because the message ID remains the same, Teams doesn’t flag the alteration, making it virtually undetectable to other participants.

This isn’t a simple phishing attack; it’s a direct manipulation of the communication stream within Teams itself.Teams security breach scenarios are now significantly more complex.

Potential Impacts and Risks

The consequences of this Teams impersonation vulnerability are far-reaching:

* Financial Fraud: Attackers could impersonate executives to authorize fraudulent transactions.

* Data Breaches: Sensitive information could be leaked or manipulated through altered messages.

* Reputational Damage: Compromised communications can erode trust with clients and partners.

* Internal Disruption: False information and altered instructions can disrupt workflows and cause confusion.

* Legal Liabilities: Altered records could have legal ramifications, especially in regulated industries.

* Supply Chain Attacks: Impersonating a vendor or partner to introduce malicious code or instructions.

Who is at Risk?

All organizations using Microsoft teams are potentially vulnerable. However, certain factors increase risk:

* Large Organizations: Larger teams with more complex communication patterns offer more opportunities for attackers.

* Industries with High-Value Targets: Financial institutions, healthcare providers, and government agencies are particularly attractive targets.

* Teams with Sensitive Data: Organizations handling confidential information (e.g., intellectual property, customer data) are at greater risk.

* Lack of Multi-Factor authentication (MFA): While MFA doesn’t directly address the message alteration issue, it strengthens overall account security and can prevent initial compromise.

Mitigation Strategies & Best Practices

while a full fix relies on Microsoft patching the vulnerability, organizations can take steps to mitigate the risk:

  1. Enable multi-Factor Authentication (MFA): Protect user accounts from initial compromise.This is a foundational security measure.
  2. User Awareness Training: Educate employees about the potential for message manipulation and encourage them to verify critical information through alternative channels (e.g., phone call, separate email). Focus on Teams phishing awareness.
  3. Implement Information Governance Policies: Establish clear policies for handling sensitive information within Teams.
  4. Monitor Teams Activity: utilize Teams audit logs and security information and event management (SIEM) systems to detect suspicious activity. Look for unusual message patterns or alterations.
  5. Least Privilege Access: Grant users only the permissions they need to perform their jobs.
  6. Regular security Audits: Conduct regular security assessments to identify and address vulnerabilities.
  7. Stay Updated: Monitor Microsoft’s security advisories and apply patches promptly. Microsoft teams updates are crucial.
  8. Consider Third-Party Security Tools: Explore security solutions designed to detect and prevent message manipulation within Teams.

Real-World Implications: Case Study (Hypothetical,Based on Observed Trends)

A mid-sized manufacturing company experienced a disruption when an attacker impersonated the CFO and altered a message approving a large wire transfer. The altered message, appearing legitimate within Teams, bypassed standard approval processes. Fortunately,the bank flagged the transaction as suspicious,preventing the financial loss. This incident highlighted the critical need for verifying financial requests through out-of-band communication channels. This is a prime example of Teams security incidents.
