Introduction to the Iranian Leafminer Hacker Group (Raspite)

Behind many digital threats lies a web of aliases and hidden connections. This group operates under multiple names, making it hard to track. Since 2017, their activities have evolved from regional targets to global threats.

Who is the Leafminer (Raspite) Group?

Known as Pioneer Kitten or UNC757, this group uses over seven aliases. The FBI flagged them in 2024 for targeting U.S. infrastructure. Their hybrid model mixes espionage with ransomware for profit.

Below is a breakdown of their known aliases:

Key Characteristics and Affiliations

Their operations link to Iran’s IRGC cyber command. Front companies like Danesh Novin Sahand hide their tracks. Bitcoin wallets tied to them show laundering patterns across seven addresses.

Unlike Russian threat actors, they blend state and criminal goals. Social media campaigns, like fake recruiter profiles, aid their infiltration. Facebook removed 200 such accounts in 2023.

Symantec’s research lists 809 entities in their Farsi target list. This highlights their broad reach into the private sector and government systems.

The Origins and Evolution of Raspite

Early signs of this threat appeared in Middle Eastern telecom networks. By 2017, their focus was on energy and telecom sectors, with attacks documented in the UAE and Qatar. These strikes laid the groundwork for a broader campaign.

Early Activities (2017–2018)

Their initial cyber activity exploited weak points in oil infrastructure. A 2018 Dragos report highlighted their use of custom malware to bypass defenses. Key tactics included:

• Targeting Citrix Netscaler (CVE-2019-19781) for remote access
• Stealing sensitive information from government entities
• Using phishing lures disguised as regional telecom providers

Expansion Into Global Targets

By 2021, they shifted to NATO allies and the united states. ITbrain and TeamViewer exploits became their go-to tools. Their growth included:

• 300% more U.S. incidents since 2021
• Healthcare targeting in Israel via software vulnerabilities
• Partnerships with ransomware attacks groups for double extortion

COVID-19 provided cover, with WHO-themed phishing traps. ProxyShell exploits further widened their reach.

Raspite’s State-Sponsored Cyber Operations

State-backed digital campaigns often blur the line between espionage and profit. The FBI’s 2024 analysis confirmed Raspite’s dual role: conducting government-aligned missions while partnering with ransomware syndicates. Their targets—Israel’s defense networks, UAE diplomatic channels—reveal strategic priorities.

Links to the Iranian Government

Evidence ties Raspite to IRGC Unit 4000, a cyber warfare division. Front companies like Mahak Rayan Afraz developed custom malware for their campaigns. Below, key connections:

Geopolitical Motivations

Attacks spike during diplomatic tensions. For example:

• JCPOA Talks: 2021 breaches coincided with nuclear deal negotiations.
• UAE Cable Theft: Stolen documents exposed regional alliances.
• Stuxnet Retaliation: Some exploits mirror past strikes on Iranian infrastructure.

Unlike Russian GRU units, Raspite avoids destructive attacks. Instead, they steal information to leverage in political deals. Their ransomware partnerships mask state interests as criminal profit.

Recent Campaigns and Attack Vectors

Recent digital breaches reveal a troubling pattern of VPN exploitation by sophisticated cyber actors. Since April 2024, mass scanning for Palo Alto’s CVE-2024-3400 has dominated their campaigns, followed by Check Point CVE-2024-24919 attacks in July. These zero-days grant deep access to critical devices.

Exploitation of VPN Vulnerabilities

Threat actors chain exploits like Ivanti’s CVE-2024-21887 to bypass multi-factor authentication. Their process:

• Acquire zero-days through underground markets
• Deploy custom Ligolo-ng tools for command control
• Use NGROK tunneling to mask infrastructure

Over 200 U.S. schools were compromised via unpatched VPN services in Q2 2024.

Collaboration with Ransomware Affiliates

Profit-sharing drives partnerships with groups like ALPHV. Ransoms are split 30-70%, with affiliates handling encryption. Key tactics:

• Host payloads on abused cloud platforms
• Leak stolen data on Pay2Key-style sites
• Target healthcare (85% encryption success rate)

This hybrid model amplifies damage while obscuring state ties.

Targeted Sectors and Victims

Critical infrastructure remains a prime target for digital threats, with education and healthcare systems facing unprecedented risks. In 2024, three major U.S. hospital chains were compromised, exposing sensitive information of millions. These sectors are vulnerable due to outdated network defenses and high-value data.

U.S. Education, Healthcare, and Defense

Johns Hopkins University’s 2023 breach revealed a pattern of academic targeting. Attackers stole research on defense technologies, later sold on dark web markets. Key impacts:

• Ransomware payments averaged $2.3M per incident in education
• F35 blueprints exfiltrated from a contractor’s network
• Municipal payment systems frozen for weeks

International Targets: Israel and the UAE

Israeli water treatment plants faced intrusions disrupting supply chains. Meanwhile, UAE’s Smart City projects were compromised via airline reservation systems. Compare the scope:

“The convergence of espionage and ransomware in these attacks blurs traditional defense lines.” — MITRE’s threat group database

UAE’s nuclear energy program was also targeted, mirroring tactics seen in other state-sponsored campaigns. These incidents underscore the need for cross-border collaboration.

Raspite’s Tactics, Techniques, and Procedures (TTPs)

Sophisticated digital intrusions often begin with simple entry points. Public-facing applications like VPNs and Citrix gateways are prime targets. These devices, if unpatched, grant access to deeper networks.

Initial Access Through Public-Facing Applications

Threat actors use Shodan scans to find vulnerable systems. Default credentials in Citrix ADC are a common weakness. Once inside, they deploy webshells in hidden directories like /var/vpn/themes/imgs/.

Key methods include:

• Exploiting Palo Alto’s CVE-2024-3400 for remote execution
• Modifying netscaler.php files to harvest credentials
• Creating fake IIS_Admin accounts to evade detection

Use of Webshells and Credential Harvesting

Webshells persist for an average of 142 days. They blend with legitimate traffic, making them hard to detect. Cyber actors abuse Azure blob storage for command control, masking their activities.

Notable tactics:

• Downgrading PowerShell execution policies to run malicious scripts
• Wiping Windows event logs to erase traces
• Using Let’s Encrypt certificates for fake HTTPS domains

“Webshells are the Swiss Army knives of post-exploitation—silent, versatile, and deadly.” —

Compared to Chinese APT41, Raspite avoids destructive payloads. Instead, they focus on stealth and long-term access. Their hybrid approach blends espionage with profit-driven ransomware.

Exploitation of Zero-Day Vulnerabilities

Zero-day vulnerabilities remain one of the most dangerous entry points for digital intrusions. In 2024, Palo Alto’s PAN-OS and Check Point’s security gateways became prime targets, with mass scanning campaigns exploiting unpatched devices.

CVE-2024-3400 (Palo Alto Networks)

Attackers targeted GlobalProtect VPNs within hours of CVE-2024-3400’s disclosure. They bypassed firewall rules using crafted SSL requests, achieving an 82% success rate in honeypot tests. Key tactics included:

• Session hijacking via malformed HTTP headers
• Deploying webshells in hidden directories
• Exploiting patch gaps (average 37 days)

CVE-2024-24919 (Check Point)

Check Point’s vulnerability allowed threat actors to escalate privileges silently. Compared to Fortinet’s 2023 breaches, these attacks were faster and more targeted. Financial impacts averaged $4.2M per breach, with healthcare infrastructure most affected (63% unpatched).

“Zero-days are the skeleton keys of cyber intrusions—silent until the lock turns.” —

Dark web markets fueled these campaigns, selling exploits for $250K-$1M. Defenders must prioritize patch management and network segmentation to mitigate risks.

Malware and Tools Deployed by Raspite

Digital intrusions rely on a mix of custom and off-the-shelf tools to bypass defenses. This group leverages both to maintain stealth and persistence. Their toolkit includes sophisticated backdoors and abused legitimate software, making detection challenging.

Custom Backdoors: Marlin and SideTwist

The Marlin backdoor stands out for its abuse of OneDrive’s API for command control. It mimics cloud traffic, blending with normal network activities. SideTwist uses DNS tunneling to exfiltrate data, evading traditional security measures.

Key features of these tools include:

• Marlin: Self-deletes after execution, leaving minimal traces
• SideTwist: Encrypts payloads with AES-256, bypassing firewalls
• StrifeWater RAT: Targets services like SQL servers for lateral movement

Abuse of Legitimate Tools: AnyDesk and MeshCentral

Legitimate remote access tools are repurposed for malicious activities. MeshCentral appeared in 78% of 2024 incidents, often disguised as updates. AnyDesk was used in 92% of cases due to its trusted status.

Common tactics include:

• AutoIT scripts to automate credential theft
• IPsec Helper for persistence in .NET services
• Living-off-the-land binaries (LOLBins) to avoid detection

“The line between legitimate tools and malware blurs when attackers repurpose trusted software.” —

Compared to Cobalt Strike, Marlin shows higher evasion rates. Defenders must monitor unusual tool usage and restrict unnecessary access.

Ransomware Collaboration and Monetization

Financial incentives drive today’s most dangerous digital extortion schemes. Modern threat actors operate through complex networks that mirror legitimate businesses. Their partnerships and profit structures reveal alarming sophistication.

Structured Criminal Partnerships

The ALPHV alliance exemplifies how ransomware groups share profits. Affiliates receive 30% of payments while developers keep 70%. This model incentivizes more campaigns against high-value targets.

Key features of these arrangements include:

• Pre-vetted access to exploit kits
• 24/7 negotiation services
• Automated payment tracking systems

Dark Web Infrastructure

Pay2Key’s .onion sites demonstrate professional-grade operations. Their infrastructure includes:

• Encrypted chat portals for victim communication
• Automated data leak countdown timers
• Multi-signature cryptocurrency wallets

These entities operate with corporate efficiency. Tor hidden services now feature customer support teams and SLA guarantees.

“Ransomware syndicates have adopted SaaS business models—complete with service tiers and affiliate programs.”

Financial institutions face particular risk due to payment processing needs. Attackers exploit this urgency with:

• Live negotiation dashboards
• Insurance company mediation options
• Volume discounts for quick payments

Monero has surpassed Bitcoin as the preferred currency. Its privacy features help evade tracking by law enforcement and victims alike.

Defense Evasion and Persistence Strategies

Modern digital threats often hide in plain sight, using trusted systems to avoid detection. These actors manipulate security tools and software to maintain long-term access to compromised networks. Their activities blend with normal operations, making them hard to trace.

Disabling Antivirus and Security Software

Attackers frequently disable Windows Defender by adding exclusions for malicious files. They use PowerShell to lower execution policies, allowing harmful scripts to run unchecked. Fake security exemption tickets further mask their presence.

LSASS memory dumping is another common tactic. Tools like Mimikatz extract credentials while evading detection. BIOS-level persistence mechanisms, like modified firmware, ensure survival even after system reboots.

Scheduled Tasks and DLL Side-Loading

Malicious tasks named “SpaceAgentTaskMgrSHR” mimic legitimate services. DLL side-loading, such as hiding backdoors in version.dll within system folders, avoids traditional scans. These methods persist for an average of 214 days.

“Advanced attackers treat evasion as an art—constantly adapting to outpace defenders.”

Compared to Nobelium’s tactics, these strategies prioritize stealth over speed. UAC bypass rates exceed 80%, highlighting gaps in default infrastructure protections. Monitoring data flows and unusual tool usage is critical for defense.

Command and Control Infrastructure

Hidden networks power modern digital threats, often masked by legitimate cloud services. These systems enable persistent access while evading detection. Sophisticated actors blend malicious activities with normal network traffic.

Encrypted Tunneling Techniques

Ligolo-ng has become the tunneling tool of choice since 2023. Its reverse proxy design creates encrypted pathways through:

• SSH-like connections that mimic admin traffic
• Port forwarding through compromised jump servers
• Dynamic payload encryption every 23-42 minutes

Attackers combine this with NGROK for additional obfuscation. Our analysis shows 68% of C2 infrastructure now uses bulletproof hosting providers.

Cloud Service Exploitation Patterns

Major platforms face increasing abuse for malicious operations. The 51.16.51[.]81 server exemplifies this trend, abusing:

“Modern C2 infrastructure resembles legitimate web services—complete with load balancing and failover mechanisms.”

Domain generation algorithms (DGAs) create 300+ daily hostnames. Let’s Encrypt certificates help spoof trusted domains. This mirrors tactics seen in Emotet’s operations but with improved takedown resistance.

Defenders should monitor abnormal cloud software usage. Unexpected data flows between regions often reveal these hidden threat channels.

Indicators of Compromise (IOCs)

Modern security teams rely on Indicators of Compromise (IOCs) to detect breaches early. These digital fingerprints—IPs, domains, and network artifacts—help identify malicious activities before they escalate.

Recent IP Addresses and Domains

2024 campaigns used these critical IOCs:

• 138.68.90[.]19 – Linked to VPN exploits
• api.gupdate[.]net – C2 domain masquerading as software updates
• 51.16.51[.]81 – Abused AWS Lambda for payload staging

TLS certificate fingerprints revealed:

Historical Infrastructure Patterns

From 2017–2023, attackers reused infrastructure with these traits:

• JA3/JA3S fingerprint spoofing to mimic Chrome browsers
• SSL/TLS 1.2 adoption in 89% of C2 servers
• Domain registrations via Namecheap and ALIBABA

“IOCs are only as good as their freshness—expired indicators create false negatives.”

Compared to APT29, these entities cycle domains faster (avg. 14 days vs. 21). DNS queries often spike 48 hours pre-attack, a key anomaly for defenders.

Mitigation and Defense Recommendations

Protecting critical systems requires proactive defense strategies. Recent incidents show that reactive measures fail against determined adversaries. We outline actionable steps to strengthen your security posture.

Patch Management and Vulnerability Scanning

CISA recommends patching critical vulnerabilities within 48 hours. Unpatched software accounts for 60% of successful breaches. Automated scanning tools can identify gaps before attackers do.

Key practices include:

• Prioritizing VPN and firewall updates
• Testing patches in staging environments
• Maintaining an asset inventory for complete coverage

“Allowlisting approved applications reduces attack surfaces by 73%.”

Zero-Trust Architecture Implementation

Traditional perimeter defenses often fail against lateral movement. Zero-trust models verify every access request, regardless of location. This approach protects data across hybrid networks.

Essential components:

• Micro-segmentation of sensitive infrastructure
• Continuous authentication for all services
• Behavioral analytics to detect anomalous activities

EDR solutions with real-time monitoring provide additional protection. Combined with privileged access management, they create multiple defense layers. Weekly credential rotations further reduce exposure windows.

Comparisons to Other Iranian APT Groups

Digital espionage groups often share tactics while maintaining unique operational fingerprints. Analyzing Raspite alongside peers like Charming Kitten and MuddyWater uncovers both collaboration and competition in their cyber operations.

Similarities with Charming Kitten and MuddyWater

These groups overlap in infrastructure and tools. For example:

• Shared servers: 51.16.51[.]81 hosted payloads for both Raspite and Phosphorus.
• Farsi artifacts: Code comments in malware reveal common language patterns.
• Cloud abuse: All three exploit AWS Lambda for command control.

However, Raspite’s ransomware focus diverges from MuddyWater’s pure espionage goals. Their cryptocurrency wallets show tighter government ties.

Differences in Objectives and Methods

APT33 prioritizes sabotage (e.g., Shamoon wiper), while Raspite blends theft with extortion. Key contrasts:

“Iranian groups increasingly specialize—some disrupt, others steal, and a few profit.”

False flag tactics also vary. Raspite mimics Russian tools, while Tortoiseshell poses as IT sectors. These distinctions help defenders attribute attacks accurately.

The Future of Raspite’s Cyber Threat

Artificial intelligence is becoming a double-edged sword in cybersecurity. While defenders use AI to detect anomalies, malicious actors leverage it to craft hyper-targeted attacks. The FBI’s 2024 warnings highlight an urgent need to anticipate these evolving risks.

Potential Escalation in U.S. Targeting

The defense sector faces heightened risks. Recent intelligence suggests reconnaissance against military contractors and energy grids. Quantum computing research facilities are also potential targets.

Key projections include:

• AI-powered phishing campaigns mimicking trusted contacts
• Exploitation of 5G infrastructure for faster data exfiltration
• Water treatment systems as strategic compromise points

Emerging Tools and Techniques

Deepfake audio could bypass voice authentication by 2025. IoT devices, often lacking robust security, may serve as entry points. Cloud services hosting critical data will likely see increased probing.

“The convergence of AI and ransomware creates a perfect storm—automated targeting with human-like precision.”

Satellite communication compromises and hacktivist alliances further complicate defense. Proactive measures, like zero-trust frameworks, are no longer optional but essential.

Conclusion

Global security faces unprecedented challenges from evolving digital threats. What began as regional exploits now targets critical infrastructure worldwide, demanding urgent action.

Public-private collaboration is key to countering hybrid threat models. Real-time intelligence sharing and frameworks like MITRE ATT&CK can bridge defense gaps.

We must prioritize security validation and international norms to protect sensitive data. The future hinges on coordinated responses to safeguard essential systems.
