Ransomware for Individuals: How Card Data and Purchase History Became a Blackmail Tool​

Classic ransomware for individuals, which blocks access to computers for a ransom, is becoming a thing of the past. In 2024-2026, targeted, multi-layered cyberextortion will emerge, where data is not the target, but merely one lever of pressure. Your payment information, browser history, correspondence, and photos become weapons in the hands of extortionists, who attack not the weakness of systems, but the weakness of social connections and the fear of reputational loss.

Evolution: From Encryption to Extortion​

• Era 1.0 (2010s): Cryptographic encryption of PC files. Threat: data loss. Ransom: cryptocurrency for the key.
• Era 2.0 (2020s): Doxware / Leakware. This malware not only encrypts but also steals sensitive data before encryption. Threat: data leakage to the public or specific individuals. Ransom: non-disclosure.
• Era 3.0 (2026): Hyper-targeted social extortion. Malware is just one possible infiltration vector. The key is analyzing the stolen data and developing a customized blackmail strategy for each individual.

How an attack on an individual now works: step by step​

Stage 1: Infiltration and data theft.

• Vectors: Phishing with a Trojan, hacking cloud synchronization (iCloud, Google Drive), compromising email passwords, software vulnerabilities.
• The purpose of the theft is not the money on the card, but:
  • Full browser history (including visits to specific websites, porn viewing, and search queries about diseases).
  • Correspondence (messengers, email, social networks).
  • Photo/video archives (personal, intimate).
  • Autofill data from a browser or password manager: logins, passwords, card numbers (with CVV), addresses, passport details.
  • Cache and session cookies from social networks and banks.

Stage 2: Analysis and compilation of a “dossier”.

• The data is analyzed manually or using scripts, and compromising materials are searched for.
• An individual "dossier" is formed, for example:
  • "You, [Name Last Name], have visited [list of specific websites]. Your Telegram conversations show [specific facts]. You have a [bank, last 4 digits] card. You have two children, they attend school No...."
• This is where card and purchase data plays a key role: Purchase history on an intimate goods website, transfers to certain services, subscriptions—all of this becomes the subject of blackmail.

Stage 3: Multi-layered pressure and blackmail (Key Stage)
The extortionist doesn't just send an automated email. They engage in dialogue, exploiting the most sensitive areas.

• Scenario A: "Silent" threat of leakage to loved ones.
  • Message: "Hello, [Name]. We have your entire adult website browsing history, your correspondence with [Name of Lover/Mistress], and your intimate photos. We also know your wife's contact information, her Facebook account, your parents' and colleagues' contact information. If $2,000 isn't deposited into this Bitcoin address within 48 hours, we'll send the collection to everyone in your contact list. Don't contact the police — it will speed up the process."
• Scenario B: Blackmail based on payment data.
  • Message: "We see that you used the card [details] to pay for [specific service name]. We know where you work at [company name from LinkedIn]. If you don't pay $1,500, we'll send screenshots of your transactions to your HR department and publish them on local social media pages in your city."
• Scenario B: Combined with the threat of hacking accounts.
  • Using stolen cookies and sessions, an attacker can threaten to hack social networks and send emails in the victim's name.

Stage 4: Monetization and "aftertaste".

• Paying the ransom (in crypto) doesn't guarantee security. You could be added to the "payers" list and blackmailed again in six months.
• Even after payment, the data can be sold on specialized forums for further use (carding, phishing, spam).

Why is it so effective? The psychology of attack​

1. The fear of social condemnation and reputational damage is stronger than the fear of losing $1,000.
2. Personalization: The threat feels real because the email contains your personal information.
3. Feeling of no escape: Calling the police seems futile and, as threatened, will make the situation worse.
4. Speed and pressure: Short deadlines (24-48 hours) leave no time for a sober assessment.

Protection and Action in 2026: Preventive Measures and the Right Response​

Prevention (difficult, but necessary):

• Hardware authentication (FIDO2 keys) for important services (mail, cloud).
• Regularly clear your browser history, autofill, and cookies (or use incognito mode for sensitive activities).
• Separation of digital lives: Using different browsers/profiles for work, personal life, banking and sensitive activities.
• Encrypt disks and cloud storage with VeraCrypt, Cryptomator.
• Refusal to store intimate and compromising materials in digital form in principle.

If the attack has already occurred:

1. DO NOT PAY. Payment does not guarantee a solution to the problem, but rather marks you as a "loyal victim."
2. DO NOT ENGAGE IN DIALOGUE. Any reaction shows you are alive and reading.
3. SAVE ALL EVIDENCE (screenshots, emails, crypto wallet addresses).
4. WARN POTENTIAL RECIPIENTS OF THE LEAK (relatives, colleagues) via a trusted channel (in person, by phone) that they may receive spam/slander.
5. COMPLETELY CLEAN DEVICES, change all passwords, revoke and reissue all bank cards specified in autofill.

Conclusion: Ransomware 3.0 is not about technology, but about the vulnerability of the human psyche.​

The attack has shifted from technical software vulnerabilities to human psychological vulnerability. Ransomware trades not in decryptors, but in peace of mind, reputation, and a sense of security.

Card data and purchase history have become not targets, but tactical tools for demonstrating awareness and increasing pressure. In this new reality, the best defense is digital asceticism, separation of identities, and a willingness to accept that no data is 100% private. The key skill of 2026 is not the ability to recover encrypted files, but the ability to psychologically survive a potential data leak without succumbing to blackmail. This makes every person the last and primary line of defense in this war.
