6-Year Ransomware Campaign Targets Turkish Homes and SMBs

A ransomware campaign that has operated continuously since at least 2019 has been targeting Turkish home users and small-to-medium businesses (SMBs), researchers have found. The campaign — spanning six years — has largely evaded the coordinated international law enforcement disruptions that have taken down higher-profile ransomware-as-a-service (RaaS) operations, highlighting a persistent blind spot in the global ransomware threat landscape: lower-profile, regionally focused campaigns that fly under the radar.

Campaign Overview

The six-year operation targets a demographic that is frequently underserved by enterprise cybersecurity infrastructure: home users running Windows without managed security tools, and SMBs with limited IT staffing and no dedicated security personnel.

Why Under-Reported Campaigns Last Longer

The threat intelligence community and law enforcement agencies allocate attention and resources proportionally to incident volume and media coverage. Ransomware operations that:

• Target individuals and small businesses rather than enterprises or critical infrastructure
• Demand smaller ransoms (hundreds to low thousands of dollars versus millions)
• Avoid hitting healthcare, government, or utilities
• Operate within a single country or language region

...frequently avoid the level of scrutiny that leads to infrastructure takedowns or criminal indictments.

This creates a structural incentive for ransomware actors to stay small, stay regional, and stay quiet — maximizing longevity at the expense of per-victim revenue.

The Turkish-targeting campaign is a textbook example of this dynamic. Enterprise-scale ransomware events make international headlines and trigger joint FBI/Europol actions. A campaign generating dozens of daily incidents against Turkish households and SMBs generates almost no English-language coverage, minimal law enforcement referrals, and effectively no disruption pressure.

Tactics, Techniques, and Procedures

While full technical attribution has not been published, the campaign's longevity suggests operators have refined their tradecraft over six years to maintain persistence and evade detection. Common TTP patterns for this class of campaign include:

Initial Access

• Phishing emails with malicious attachments (Word documents, PDFs, ISO files)
• Cracked software distributed via Turkish-language forums and torrent sites
• Remote Desktop Protocol (RDP) brute force against consumer routers and small business servers with externally exposed RDP

Targeting Home Users Specifically

Home users represent an attractive target for regional ransomware operators because:

1. No incident response capability — no IT team, no EDR, no backups in most cases
2. High payment likelihood — personal files (photos, documents) often have high emotional value
3. Low law enforcement reporting rate — individuals rarely report ransomware incidents to authorities
4. Windows Home editions — no Group Policy, no centralized management, often unpatched

SMB Vulnerabilities

Small businesses face similar challenges at a slightly larger scale:

• Reliance on consumer-grade networking equipment without proper firewall rules
• Shared drives used as primary storage with no backup strategy
• Outdated software — legacy Windows versions, unpatched Office, old third-party software
• Single administrator managing multiple business functions with no security specialization

The Broader Pattern: Underreported Regional Campaigns

Turkey is not uniquely targeted — similar long-running regional campaigns have been documented targeting:

• Eastern European SMBs via Russian-language crimeware forums
• Southeast Asian home users via fake software update sites
• Latin American businesses via Spanish-language phishing

The common thread is that these campaigns thrive precisely because the affected populations are underrepresented in global threat intelligence datasets. Most threat feeds draw heavily from large enterprise incident reports, English-language dark web monitoring, and US/European law enforcement disclosures.

Detection and Mitigation for Home Users and SMBs

For Home Users

1. Maintain offline backups — an external drive disconnected when not in use is immune to ransomware encryption
2. Disable RDP if not needed (Settings → System → Remote Desktop → Off)
3. Use Windows Defender — it is free, built-in, and effective against known ransomware families
4. Do not download cracked software — this is the most common initial access vector for home-targeting ransomware
5. Keep Windows and Office updated — enable automatic updates

For SMBs

1. Implement the 3-2-1 backup rule — 3 copies, 2 different media types, 1 offsite or air-gapped
2. Restrict RDP to VPN only — never expose RDP directly to the internet
3. Enable MFA on all remote access — VPN, RDP, remote management portals
4. Patch systematically — prioritize internet-facing systems and software known to be targeted by ransomware (RDP, VPN clients, mail servers)
5. Deploy endpoint protection — even basic endpoint detection and response tools dramatically reduce dwell time

# Windows: disable RDP if not required
Set-ItemProperty -Path 'HKLM:\System\CurrentControlSet\Control\Terminal Server' `
  -Name "fDenyTSConnections" -Value 1
 
# Verify RDP is disabled
Get-ItemProperty -Path 'HKLM:\System\CurrentControlSet\Control\Terminal Server' `
  -Name "fDenyTSConnections"

Implications for the Threat Landscape

The six-year Turkish campaign is a reminder that persistence and patience are competitive advantages for ransomware operators who deliberately avoid the spotlight. While the security community celebrates takedowns of REvil, BlackCat, LockBit, and other headline operations, hundreds of smaller campaigns continue operating against under-resourced victims globally.

Addressing this blind spot requires:

• Expanded local-language threat intelligence — monitoring regional forums, local news, and non-English social media for campaign indicators
• Better reporting infrastructure for individuals and SMBs — most national CERTs are not well-equipped to handle high-volume individual ransomware reports
• International information sharing — regional campaigns often operate from third countries and require cross-border coordination to disrupt

For security professionals, this campaign serves as a useful benchmark for organizational posture: if your defenses would fail against a six-year-old regional operation with no known sophisticated TTPs, your baseline hygiene has room for improvement.
