What is Majinahanashi Ransomware?

Majinahanashi is a double-extortion group that began posting victims to its Tor leak site in mid-2026, with trackers counting between 14 and 19 claimed targets across a dozen countries in their late-August 2026 snapshots. Its Windows encryptor wraps per-file AES-256 keys under an embedded RSA key and wipes shadow copies before dropping its ransom note. BeforeCrypt checks for available decryption tools, including free ones, as part of every assessment. Recovery often depends on offline or immutable backups. BeforeCrypt can help contain the attack, confirm what was exfiltrated and assess which recovery options apply.

Why You Shouldn’t Attempt to Fix It Alone

BeforeCrypt checks for available decryption tools, including free ones, as part of every assessment. The per-file AES-256 keys are wrapped with an RSA public key embedded in the binary, and without the attacker-held private key file recovery normally depends on offline or immutable backups. Running an unverified tool against live files can make recovery harder, which is why BeforeCrypt tests any candidate tool on copies first and assesses which decryption and recovery options actually apply to your environment.

Majinahanashi exfiltrates data before encrypting, and leak-site listings have included customer records, medical imaging archives and ERP/CRM backups — so even full backup recovery doesn’t remove the risk of stolen data being published or sold. This is an additional risk for your business, separate from the encrypted files themselves. Notification obligations depend on your sector and geography — see the FAQ below for the regulatory clocks that may apply.

BeforeCrypt provides full incident response where a client has no internal capacity, or works alongside an existing IT team on containment, eradication and recovery. We establish what data was actually taken, screen any proposed payment against sanctions lists, preserve evidence for insurers and regulators, and coordinate notification timelines. Where it’s the right option, our team handles negotiation with the attackers — including reducing the demand and buying time. Running technical response, internal coordination, customer and regulator communication and any attacker contact all at once strains even well-resourced internal teams.

An experienced internal security team can handle substantial parts of the response itself. Our detailed emergency response plan walks through the sequence step by step. A free assessment call with our team helps you decide quickly which parts to keep in-house and where specialist support saves time.

COMMON ATTACK VECTORS

Documented techniques associated with Majinahanashi intrusions and deployment:

  • Valid Accounts / External Remote Services (T1078 / T1133) — in 2026 analysts assessed compromised VPN, remote-access or M365 credentials as the likely entry point, with trackers noting that roughly half of claimed victim domains showed infostealer credential exposure.
  • Remote Services: SMB/Windows Admin Shares (T1021.002) — the encryptor is pushed to the ADMIN$ share for remote execution across the network.
  • OS Credential Dumping (T1003) — operators have reused Mimikatz for credential access.
  • Network Service Discovery (T1046) — Advanced IP Scanner is used to map the network before deployment.
  • Inhibit System Recovery (T1490) — shadow copies, the USN journal, System Restore and boot-recovery settings via bcdedit are disabled or deleted before encryption.

RANSOM AMOUNTS

Majinahanashi mainly targets mid-sized manufacturers, e-commerce firms and healthcare organisations in Europe, Asia and Latin America, with analysts assessing compromised VPN, remote-access or M365 credentials as the likely entry point.

In one documented email exchange with the operators, the threat actor demanded USD 15,000 and supplied a Bitcoin address. Ransoms are usually paid in Bitcoin. Quick-buy methods of purchasing Bitcoin with PayPal or credit cards do not work for this size of ransom payment and it is important to obtain expert advice to ensure that a payment of this size is legally compliant.

Where negotiation is the right option, our experienced negotiation team has consistently secured meaningful reductions from the initial demand to the final settlement across Majinahanashi engagements.

AVERAGE LENGTH

Majinahanashi disables Windows recovery options before encrypting — deleting shadow copies, clearing the USN journal, disabling System Restore and hibernation, and modifying boot-recovery settings via bcdedit — removing the fastest paths back to a clean system.

For most ransomware victims, downtime is the most costly aspect of the incident, with potential for considerable reputational harm.

Our extensive experience with Majinahanashi ransomware gives us a deep understanding of the gang’s tactics, enabling us to resolve attacks swiftly and restore your files.

How to identify majinahanashi ransomware

Majinahanashi drops a README.txt note in encrypted folders that describes the per-file AES-256 encryption scheme, lists a qTOX ID and Proton Mail address for contact, and sets a seven-day deadline before threatening full publication of stolen data.

README.txt
All your files have been encrypted with a unique AES-256 key per file, and those keys have been secured under an offline key that only we hold. Your backups and shadow copies have been removed — do not waste time trying to restore them. We have also copied your internal data before encryption. Two files will be decrypted for free as proof that recovery is possible. Contact us within 7 days using the details below: qTOX ID: [.redacted] Email: [.redacted] Case ID: [.redacted] Tor disclosure site: [.redacted] If no agreement is reached within the deadline, your data will be published in full and we will notify your regulators, clients and affected parties. Do not involve intermediaries, recovery consultants or law enforcement — this will only harm your chances of recovery.

Frequently asked questions

How Does Ransomware Encrypt Files?

Ransomware encrypts files using advanced cryptographic algorithms, typically AES (Advanced Encryption Standard) or RSA (Rivest-Shamir-Adleman). Once executed, the malware scans the system for specific file types and encrypts them, making them inaccessible to the user. Some variants use symmetric encryption (AES), while others combine it with asymmetric encryption (RSA) to lock files with a unique key pair.

Can You Decrypt My Ransomware Encrypted Files?

Decryption depends on the ransomware variant. In some cases, publicly available decryption tools exist, but not all attacks have a known solution. You can submit a free ransomware recovery request, and we will check for possible decryption methods.

Do I have to report a ransomware attack to regulators, and when?

In most cases involving personal data, which applies to nearly every ransomware incident, reporting is legally required. In the EU, GDPR requires notification to the relevant data protection authority within 72 hours of becoming aware of a personal data breach. The UK ICO requires the same 72-hour window. In the US, HIPAA-covered entities have 60 days to notify affected individuals (and immediately for breaches affecting 500+ people). The clock starts from awareness of the incident, not from a full technical understanding.

Is it legal to pay a ransom?

In most jurisdictions, paying a ransom is not illegal in itself — but it can become illegal if the payment ends up going to a sanctioned entity or country (OFAC-designated groups in the US, EU sanctions lists, UK Treasury lists). Before any payment, sanctions screening is essential. BeforeCrypt handles this compliance layer as a standard part of every engagement.

Will paying the ransom actually get my files back?

Most established ransomware groups do provide working decryption tools when paid — the business model depends on their reputation for delivery. However, decryptors are often slow, incomplete, or corrupt a percentage of files during recovery. This is where working with a specialist matters: BeforeCrypt tracks the delivery reliability of specific groups, negotiates sample-file decryption as proof of capability where the group allows it, and plans realistic recovery timelines based on our own engagement history with each group.

What happens if we don't pay the ransom?

Most modern ransomware groups follow through on publication threats — stolen data appears on the group's leak site, is often mirrored to Telegram and dark web forums, and may be sold to third parties. Recovery becomes limited to whatever you can rebuild from backups.

Are our files still at risk if we have working backups?

Backups protect against file loss but not against data theft. Most modern ransomware groups exfiltrate sensitive data BEFORE encryption and threaten to publish it regardless of your recovery capability. This is why leak-site publication and negotiation still matter even for organisations with clean, offline backups — and why "we can just restore from backup" rarely tells the full story.

Should we contact law enforcement after a ransomware attack?

In most jurisdictions, yes — reporting is a standard part of a ransomware incident and, in some cases, legally required. In the US, that means the FBI (via IC3 or a local field office) and CISA. In the EU, national CERT and cybercrime units. Reporting does not obligate you to any specific recovery path but does open access to threat intelligence and, occasionally, decryption tools recovered by law enforcement.

Do you have deep experience with ransomware incidents?

Yes. We’ve handled 1,700+ incidents across ransomware, BEC and data-leak extortion. We identify the variant, decide decrypt vs. clean verified restore, and guide a controlled return to operations. When needed, we support negotiation & compliance—always legally and with a clear audit trail.

Will insurers accept your findings and reports?

Yes. We produce insurer-ready incident reports with a defensible timeline, scope, likely entry path, exfiltration assessment, actions taken, and chain-of-custody. We can join the adjuster call, map our findings to your carrier’s forms, and provide GDPR/NIS2 notifications where required. Final acceptance always depends on the policy and carrier, but our packages are designed to speed up approvals and reduce back-and-forth.

How is this different from my MSP or the insurer’s hotline?

MSPs keep IT running; they’re not built for evidence handling and incident triage. Insurer panels optimize claims, not necessarily speed & clarity for your business. We work alongside both: kick off in ≤2h, run forensic triage with chain-of-custody, coordinate safe containment, and deliver executive- and insurer-ready findings—without taking your environment hostage.

Why Should I Use A Cyber Incident Service?

Because it turns chaos into fast, safe recovery. We cut downtime and limit damage while preserving evidence. Within ≤48h you get a forensic triage pack (timeline, likely entry path, scope, decrypt-vs-clean-restore decision, go-live criteria) so leadership can act with confidence. Result: controlled, verified restart—not guesswork.
