What Is Medusa Ransomware? — The Complete Answer
Before we break down the Medusa ransomware gang phishing campaigns in detail you need to understand exactly what you are dealing with.
Medusa is a ransomware-as-a-service (RaaS) variant first identified in June 2021. As of February 2025 Medusa developers and affiliates have impacted over 300 victims from a variety of critical infrastructure sectors with affected industries including medical, education, legal, insurance, technology, and manufacturing.
The group mostly targets small and medium-sized entities with revenues ranging from US $5 million to US $50 million. The group practices double extortion where sensitive data is first discreetly extracted from systems that have been compromised. If an organisation does not pay a ransom for the decryption key Medusa threatens to release data on its data leak blog which it launched in 2023.
Here is what makes Medusa ransomware different from other ransomware-as-a-service groups — and far more dangerous:
| Feature | Detail |
|---|---|
| Type | Ransomware-as-a-Service (RaaS) |
| First Identified | June 2021 |
| Operating Model | Developers recruit affiliates via credential harvesting IABs |
| Extortion Method | Double extortion ransomware — encrypt AND publish data |
| Leak Site | Medusa Blog — dark web leak site launched 2023 |
| Ransom Range | $100,000 to $15 million per victim |
| Confirmed Victims | 500+ as of January 2026 |
| Attack Frequency | Near-daily in 2025 |
| Primary Entry | Medusa phishing campaigns and unpatched vulnerabilities |
| Affiliate Payments | $100 to $1 million per successful attack |
⚠️ Critical Note: The Medusa ransomware variant is completely unrelated to the MedusaLocker variant and the Medusa mobile malware variant per the FBI’s investigation. These are three entirely separate threats with no connection to each other.
The Shocking FBI Warning About Medusa Ransomware Gang Phishing Campaigns
Medusa is a ransomware-as-a-service variant used to conduct ransomware attacks — as of December 2024 over 300 victims from critical infrastructure sectors have been impacted. Medusa actors use common techniques like phishing campaigns and exploiting unpatched software vulnerabilities.
The Medusa ransomware gang routinely engages in double extortion where they demand an extortion payment to not publish stolen patient data and a payment for the decryption key to unlock encrypted data and systems. This gang exploits stolen credentials and known vulnerabilities.
And here is the part that should genuinely alarm every organisation — the discovery of triple extortion:
FBI investigations identified that after paying the ransom one victim was contacted by a separate Medusa actor who claimed the negotiator had stolen the ransom amount already paid and requested half of the payment be made again to provide the true decryptor — potentially indicating a triple extortion scheme.
Read that again. Victims who paid the ransom were extorted a second time by the same gang. Paying does not guarantee safety — it guarantees you become a target again.
Medusa Ransomware 2025 — The Shocking Statistics
The data tells the real story of how dangerous Medusa ransomware gang phishing campaigns have become in 2025:
| Statistic | Figure | Source |

How Do Medusa Ransomware Gang Phishing Campaigns Actually Work?
This is the section that could save your organisation. Understanding exactly how Medusa ransomware gang phishing campaigns operate step by step is your single most powerful defence.
Step 1 — Credential Harvesting Through Medusa Phishing Campaigns
Medusa IAB affiliates are known to make use of phishing campaigns as a primary method for stealing victim credentials and exploiting unpatched software vulnerabilities through Common Vulnerabilities and Exposures such as the ScreenConnect vulnerability and Fortinet EMS SQL injection vulnerability.
These Medusa phishing attacks are no longer simple spam emails. More sophisticated targeted spear phishing attacks have been reported that use AI to craft more believable text to better convince victims to click on links or download attachments that result in the ransomware’s installation.
7 Types of Medusa Gang Phishing Campaign Emails:
| Phishing Email Type | What It Pretends to Be | Risk Level |
|---|---|---|
| Delivery notices | FedEx, UPS, USPS, DHL packages | 🔴 Very High |
| Purchase receipts | Amazon, Walmart, Target orders | 🔴 Very High |
| Virus alerts | Fake IT security notices | 🔴 Very High |
| Voicemail messages | Audio message download links | 🟡 High |
| Financial documents | Fake invoices and payment requests | 🔴 Very High |
| Boss impersonation | CEO asking for urgent action | 🔴 Very High |
| Security software | Prompts to download fake tools | 🟡 High |
Step 2 — Living Off the Land (LoTL) After Medusa Phishing Access
Once the Medusa phishing campaign delivers initial access the gang does something extremely clever — they use your own legitimate tools against you to avoid detection.
Once inside a network Medusa employs sophisticated strategies to maximise impact. The group executes Base64-encrypted commands via PowerShell to avoid detection and utilises tools like Mimikatz to extract credentials from memory facilitating further network compromise. They also leverage legitimate remote access software including AnyDesk and ConnectWise as well as tools like PsExec and RDP to propagate across the network.
This living off the land attack technique makes the Medusa ransomware gang extremely difficult to detect because their activity looks identical to normal IT operations.
Step 3 — Credential Theft and Lateral Movement
The Medusa gang phishing campaign does not stop at credentials — it goes much deeper. After gaining initial phishing campaign access attackers use Mimikatz for credential theft then move laterally across your entire network using Remote Desktop Protocol (RDP) stealing data from every system they can reach.
Medusa ransomware increasingly exploits remote monitoring and management (RMM) tools for persistence, lateral movement, and data exfiltration. Threat actors including nation-state actors and ransomware groups like Medusa abuse legitimate commercial RMM tools typically used by system administrators for remote monitoring, software deployment, and device configuration instead of relying on remote access trojans.
Step 4 — Disabling Your Endpoint Detection and Response
In some instances Medusa actors attempted to use vulnerable or signed drivers to kill or delete endpoint detection and response (EDR) tools.
This is the Bring Your Own Vulnerable Driver (BYOVD) attack — one of the most sophisticated critical infrastructure attack techniques in the ransomware toolkit designed specifically to neutralise your defences before the final encryption blow.
Step 5 — Data Exfiltration Before Encryption
This final stage of the Medusa ransomware phishing campaign is devastating — and is what makes the double extortion model so powerful.
Encryption processes add a .MEDUSA extension to each of the victim’s files. Ransom notes are delivered via a !!!READ_ME_MEDUSA!!!.txt that provides instructions a unique identifier and warnings of future actions if payment is not made. The attack is then announced on the Medusa Blog.
The Complete Medusa Ransomware Gang Phishing Campaign Attack Chain:
| Phase | Action | Tools Used |
|---|---|---|
| 1. Medusa Phishing Campaign | Credential harvesting via phishing emails | AI-enhanced spear phishing |
| 2. Initial Access | Login with stolen credentials or exploit CVE | CVE-2024-1709, CVE-2023-48788 |
| 3. Reconnaissance | Map network targets | Advanced IP Scanner, SoftPerfect |
| 4. Credential Theft | Extract passwords from memory | Mimikatz, keyloggers |
| 5. Lateral Movement | Spread across network | RDP, PowerShell, PsExec |
| 6. Defence Evasion | Kill EDR and antivirus tools | BYOVD techniques |
| 7. Data Exfiltration | Steal all sensitive data | Tor, PowerShell scripts |
| 8. Encryption | Encrypt files — add .MEDUSA extension | Custom encryption engine |
| 9. Cyber Extortion | Demand ransom with countdown timer | Medusa Blog, dark web leak site |

Can Medusa Ransomware Be Decrypted? — Honest Answer
One of the most important questions victims of Medusa ransomware gang phishing campaigns ask is whether Medusa ransomware decryption is possible without paying.
Here is the completely honest answer:
| Medusa Ransomware Decryption Option | Feasibility | Important Notes |
|---|---|---|
| Pay the ransom | Risky — not recommended | Triple extortion risk confirmed by FBI |
| Free decryption tool | Not available | No public decryptor exists currently |
| Restore from backup | ✅ Best option | Only works if backups are clean and offline |
| Law enforcement assistance | Limited | Report to FBI IC3 — they may have tools |
| Negotiate ransom down | Sometimes possible | Professional ransomware negotiators exist |
The most alarming Medusa ransomware decryption reality comes directly from the FBI:
After paying the ransom one victim was contacted by a separate Medusa actor who claimed the negotiator had stolen the ransom amount already paid and requested half of the payment be made again to provide the true decryptor — potentially indicating a triple extortion scheme.
FutureCyber.it recommendation: Never pay the ransom. Report immediately to FBI IC3 at ic3.gov and restore from offline backups.
Medusa Android — Is It the Same as Medusa Ransomware?
Many people searching for Medusa ransomware also search for Medusa Android. Here is the critical clarification:
The Medusa ransomware variant is completely unrelated to the MedusaLocker variant and the Medusa mobile malware variant per the FBI’s investigation.
TgToxic — also known as ToxicPanda — is a rapidly evolving Android banking trojan targeting users in Asia and Europe that is sometimes confused with Medusa Android malware. The malware is distributed via dropper APKs likely through phishing or SMS campaigns.

Q: What is the Medusa ransomware gang? A: The Medusa ransomware gang is a ransomware-as-a-service (RaaS) group first identified in June 2021. It recruits affiliate partners via initial access brokers who conduct Medusa phishing campaigns and exploit unpatched vulnerabilities to gain entry. The gang uses double extortion ransomware tactics — encrypting data and threatening to publish it on their dark web Medusa Blog. As of January 2026 more than 500 organisations have fallen victim to Medusa ransomware.
Q: How do Medusa ransomware gang phishing campaigns work? A: Medusa ransomware gang phishing campaigns work in five stages. First affiliates send spear phishing attacks via email pretending to be delivery notices, invoices, or virus alerts to steal employee credentials. Second they use those stolen credentials to access the network. Third they deploy living off the land attack techniques using legitimate tools like PowerShell and RDP to move laterally. Fourth they disable endpoint detection response tools using BYOVD attacks. Fifth they exfiltrate all data then encrypt everything adding a .MEDUSA extension before demanding ransom.
Q: What did the FBI say about Medusa ransomware in 2025? A: The FBI issued a joint advisory with CISA and MS-ISAC on March 12 2025 warning that Medusa ransomware gang phishing campaigns have impacted over 300 critical infrastructure victims. The advisory revealed Medusa uses credential harvesting phishing and vulnerability exploitation for access, living off the land attacks to evade detection, and a potential triple extortion scheme where victims who pay are subsequently extorted again. The FBI urges all victims to report to ic3.gov immediately.
Q: Is there a Medusa ransomware decryption tool? A: No free public Medusa ransomware decryption tool currently exists. Restoring from clean offline backups is the only guaranteed recovery method. The FBI strongly advises against paying the ransom because confirmed cases of triple extortion show that paying does not guarantee you receive a working decryptor — it may simply make you a target for a second demand.
Q: What industries does the Medusa ransomware gang target? A: The Medusa ransomware gang phishing campaigns target critical infrastructure sectors including healthcare, education, legal, insurance, technology, and manufacturing. Notable victims include Toyota Financial Services hit with an $8 million ransom demand, Minneapolis Public Schools, and 500+ total organisations confirmed by January 2026. The gang primarily focuses on small and medium businesses with revenues between $5 million and $50 million.
Q: What are Medusa ransomware TTPs? A: Medusa ransomware TTPs include phishing campaigns for credential harvesting (T1566), exploitation of CVE-2024-1709 and CVE-2023-48788 (T1190), PowerShell Base64 execution (T1059.001), Mimikatz for credential theft, RDP for lateral movement, BYOVD attacks to kill endpoint detection response tools (T1562.001), and Tor plus PowerShell for data exfiltration before adding the .MEDUSA extension. Remote access tools abused include AnyDesk, ConnectWise, and Splashtop.
Q: What is the security risk of phishing in 2025? A: The security risk of phishing in 2025 is the single biggest cybersecurity threat facing organisations today. Phishing is responsible for 70% to 90% of all successful cyberattacks including Medusa ransomware gang phishing campaigns. The average cost of a phishing-caused breach is $4.9 million. AI-enhanced spear phishing attacks used by the Medusa gang have a 3x higher success rate than traditional phishing. Without regular training 1 in 3 employees will click a phishing email — with training that drops to 1 in 20.
Q: Is Medusa Android the same as Medusa ransomware? A: No. Medusa Android is a completely separate banking trojan that steals banking credentials and SMS messages from Android devices. It has no connection to the Medusa ransomware gang phishing campaigns described in the FBI advisory. The FBI has confirmed the Medusa ransomware variant is unrelated to both MedusaLocker and the Medusa mobile malware varian
Q: What is the Medusa ransom gang blog? A: The Medusa ransom gang blog — also called the Medusa Blog — is a dark web leak site launched in 2023. When victims of Medusa ransomware gang phishing campaigns refuse to pay the ransom the gang publishes their stolen data publicly on this site with countdown timers.
