INC ransomware is a sophisticated, professionally developed file-encryption malware that has been actively deployed against businesses since mid-2026. Unlike many copycat variants circulating online, INC represents a significant technical evolution in ransomware design: it's written entirely in Rust, uses military-grade cryptography with hardware acceleration, and employs advanced Windows API features to encrypt files even when they're actively being used by database servers or other business applications. Security researchers have confirmed that INC operators are exploiting recently disclosed vulnerabilities in enterprise software to gain initial access, then deploying this fast-moving encryption payload to maximize damage before IT teams can respond.

How It Spreads
INC ransomware doesn't rely on traditional email spam or fake software downloads. Instead, the operators behind this threat are systematically scanning the internet for vulnerable enterprise systems and leveraging recently disclosed security flaws to break in. The three CVEs confirmed by CISA—covering everything from low-code development platforms (Langflow) to web browsers (Chromium) to network switches (Arista EOS)—indicate a well-resourced group actively monitoring security bulletins and weaponizing exploits within days of public disclosure. Once they gain a foothold, attackers move laterally through the network, escalate privileges, and deploy the INC executable when they've positioned themselves for maximum impact.
For home users and small businesses in Roswell, the most common entry points we've observed are:
- Exploited vulnerabilities in unpatched software — especially web-facing applications, development tools left exposed to the internet, or outdated browser components on workstations
- Compromised Remote Desktop Protocol (RDP) access — weak passwords on Windows machines with RDP enabled and exposed to the internet remain a perennial favorite for ransomware operators
- Credential theft through prior infections — earlier malware (often information stealers) may have already harvested login credentials, which attackers purchase on criminal forums and use to gain legitimate-looking access
- Supply-chain compromise — in at least one documented case, attackers compromised a third-party software vendor and pushed malicious updates to downstream customers
What makes INC particularly dangerous is its speed. Because it's written in Rust—a modern systems programming language known for performance—and because it leverages hardware-accelerated AES encryption via Intel's AES-NI instruction set, the malware can encrypt thousands of files per minute on a typical business workstation. By the time most users notice something is wrong, their documents, databases, and backups are already locked.
What It Does On Your Machine
Once executed, INC ransomware operates with surgical precision. The malware uses a multithreaded producer-consumer architecture, meaning it divides the work of finding and encrypting files across multiple CPU cores simultaneously. It scans your drives for valuable data while intentionally skipping Windows system directories (like C:\Windows, C:\Program Files, and user-specific AppData folders) to avoid crashing the operating system before encryption completes. The goal isn't to brick your computer—it's to encrypt your irreplaceable files while leaving the machine functional enough for you to read the ransom note and make payment.
The encryption itself uses a hybrid cryptographic scheme that's effectively unbreakable without the attacker's private key. For each file, INC generates a unique AES key, encrypts the file content using AES in Counter (CTR) mode, then wraps that unique key using Elliptic Curve Diffie-Hellman (X25519). This means even if you recover one decryption key, it won't help with any other file. The mathematical security of this approach is the same foundation used by secure messaging apps and military communications—there is no "crack" or "free decryptor" for properly implemented modern ransomware like INC.
One of the most sophisticated features of INC is its use of the Windows Restart Manager API. When the malware encounters a file that's currently open—say, a SQL Server database or an Outlook PST file—it doesn't simply skip it. Instead, INC queries the Restart Manager to identify which applications are holding locks on the file, forcibly terminates those processes, encrypts the now-available file, and optionally restarts the application afterward. This capability is why businesses running 24/7 database servers have been hit particularly hard: files that should theoretically be "protected" by active use are still vulnerable.
After encryption completes, you'll find ransom notes in every folder containing encrypted files. These notes typically include a Tor-based contact URL, a unique victim ID, and instructions for paying in cryptocurrency (usually Bitcoin or Monero). The operators behind INC have demonstrated willingness to negotiate, but paying the ransom funds criminal enterprises and provides no guarantee of data recovery—we've seen cases where decryption tools provided by attackers were buggy or incomplete.
Manual Removal — Step by Step
Isolate the Infected Machine
Immediately disconnect from all networks—unplug the Ethernet cable and disable Wi-Fi. If you're on a business network, alert your IT department before proceeding. Remove any external drives, USB sticks, or mapped network shares. Ransomware actively seeks additional targets, and leaving network connections active gives it opportunities to spread.
Boot Into Safe Mode with Networking
Restart your computer and repeatedly press F8 (or Shift+F8 on newer systems) during boot. Select "Safe Mode with Networking" from the menu. This loads Windows with minimal drivers and prevents most malware from auto-starting, giving you a cleaner environment to work in. On Windows 10/11, you may need to use the Settings app > Update & Security > Recovery > Advanced Startup instead.
Document Everything Before Making Changes
Take photos with your phone of any ransom notes you see. Note the file extension added to encrypted files (.INC in this case) and the locations where you find README files. If you're considering professional recovery, this documentation helps specialists identify the exact variant and assess recovery options. Do NOT delete ransom notes until you've saved copies elsewhere.
Run a Full System Scan with Updated Security Software
If your antivirus is already installed, update its definitions (you'll need that network connection) and run a full system scan. If you don't have protection or your existing software failed to prevent infection, download Malwarebytes Free or Kaspersky Virus Removal Tool from a clean computer, transfer via USB, and scan. Most modern security tools recognize INC ransomware executables, but they cannot decrypt files—they can only remove the active infection and prevent re-infection.
Check and Remove Persistence Mechanisms
Press Windows+R, type msconfig, and check the Startup tab (or use Task Manager > Startup on Windows 10/11). Disable any unfamiliar entries, especially those pointing to C:\ProgramData or random-named executables. Then open Registry Editor (regedit), navigate to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run, and delete suspicious value entries. Be cautious—only remove items you can verify as malicious.
Manually Hunt for Malware Remnants
Use File Explorer to check C:\ProgramData, C:\Users\Public, and your personal %TEMP% folder (C:\Users\[YourName]\AppData\Local\Temp). Look for recently created executables with random names or files modified on the date of infection. Delete anything suspicious. INC typically doesn't leave extensive remnants once encryption completes, but the initial dropper or supporting scripts may still be present.
Attempt File Recovery from Shadow Copies
Right-click on an encrypted file, select Properties > Previous Versions. If Windows System Restore was enabled and the ransomware didn't delete Volume Shadow Copies (many do), you may see earlier versions of files available for restoration. This is a long shot with INC—the malware is typically sophisticated enough to purge shadows—but worth attempting for critical documents. Alternatively, use ShadowExplorer (free tool) to browse available shadow copies more thoroughly.
Restore from Backups (If Available)
If you have backups on external drives that were NOT connected during the infection, or cloud backups that weren't synced in real-time, now is the time to use them. Before restoring, ensure the malware is completely removed (re-scan with multiple tools) and consider doing a clean Windows reinstall first. Restoring files onto a still-infected system will just result in re-encryption.
Check for Free Decryption Tools
Visit NoMoreRansom.org and search for INC-specific decryptors. As of this writing, no free decryption tool exists for properly encrypted INC ransomware due to the mathematical strength of its cryptography. However, security researchers occasionally find implementation flaws in specific variants that enable free recovery, so it's worth checking. Never download "decryptors" from random websites—they're often malware themselves.
Consider Professional Data Recovery Options
If your files are critical and you have no backups, consult with a professional data recovery service before making any further changes to the drive. In some cases, forensic recovery of partially overwritten files or exploitation of ransomware bugs can retrieve data, but this requires specialized tools and expertise. Computer Repair Roswell partners with certified data recovery labs for cases beyond our in-shop capabilities.
Prevention
- Implement the 3-2-1 backup strategy — Keep three copies of your data on two different types of media, with one copy stored offsite (or in disconnected/immutable cloud storage). This is your ultimate insurance against ransomware. Backups that are always connected or automatically synced will be encrypted along with your primary files.
- Patch everything, immediately — The CVEs exploited by INC operators were all disclosed publicly before being weaponized. Enable automatic updates for Windows, all browsers, and any business software. For applications that don't auto-update, establish a monthly patching routine and stick to it religiously.
- Secure or disable Remote Desktop Protocol — If you don't absolutely need RDP access from outside your local network, turn it off entirely. If you must use it, require VPN access first, enforce strong passwords (or certificate-based authentication), change the default port, and implement account lockout policies after failed login attempts.
- Deploy reputable endpoint protection and keep it updated — Consumer-grade antivirus is better than nothing, but business environments should consider enterprise EDR (Endpoint Detection and Response) solutions that can detect behavioral anomalies like mass file encryption or Restart Manager abuse. For home users, we recommend at minimum Windows Defender (kept updated) plus Malwarebytes Premium.
- Restrict user privileges — Don't run daily operations with administrator accounts. Ransomware executed under a limited user account can still encrypt that user's files, but it struggles to install system-wide persistence or modify security settings. Use separate admin accounts only when installing software or making system changes.
- Enable and monitor Windows Defender Application Control or AppLocker — These Windows features can prevent executables from running out of unusual locations like C:\ProgramData or user temp folders. It requires some configuration effort but dramatically reduces malware's ability to execute on your system.
- Train users to recognize social engineering — While INC primarily spreads through technical exploitation, the credentials and access attackers need often come from phishing or pretexting. Regular security awareness training for employees (or family members using shared computers) reduces the likelihood of credential theft.
- Implement network segmentation — Business networks should separate critical servers from workstations, and guest Wi-Fi from internal systems. When ransomware lands on one machine, proper segmentation slows or stops its lateral movement, potentially containing damage to a single endpoint instead of your entire infrastructure.
