Hackers are using data science less as a replacement for traditional cybercrime than as a force multiplier. They collect and combine personal information, score potential victims, tailor messages, automate repetitive attacks, manufacture convincing identities, and rank stolen accounts for resale or further fraud.
The scale is significant, although the available figures are not a complete measure of global cybercrime. The FBI recorded more than $20 billion in reported U.S. internet-crime losses from more than one million complaints in 2025. Its report also recorded 22,364 complaints with an AI nexus and adjusted losses exceeding $893 million. Separately, the FTC said consumers reported losing $2.1 billion to scams that started on social media in 2025.
The key point for consumers and businesses is simple: the most dangerous innovation is often not a spectacular deepfake. It is the hidden pipeline behind an ordinary scam: collect, enrich, score, personalize, automate, escalate, monetize, and reuse.
What “data science” means in a hacking context
In this context, data science means using data to make criminal decisions more efficiently. A criminal operation may:
#1 Best Overall
- Collect information from public posts, breaches, phishing submissions, compromised accounts, or criminal marketplaces.
- Combine records that originally appeared unrelated.
- Find patterns and infer a target’s interests, relationships, job, location, or likely financial value.
- Predict which people, accounts, or messages are most likely to produce a result.
- Automate decisions and repetitive activity.
- Measure responses and improve the next attempt.
Artificial intelligence is the broad category of systems that perform tasks associated with human intelligence. Machine learning uses data to learn patterns and make predictions. Data science is broader still: it includes collecting, cleaning, analyzing, modeling, and applying data to decisions.
That distinction matters. A scam involving an AI-written sentence is not necessarily an advanced machine-learning operation. A spreadsheet, database match, rules engine, segmentation system, or feedback loop can be highly effective. The meaningful change is usually the combination of data, automation, and rapid measurement—not the presence of an “AI” label.
1. Profiling victims and precision-targeting them
Criminals use available signals to decide who is worth contacting, which story might work, which channel to use, and how much to request. Public social-media posts, breached data, advertising-style audience segments, and compromised accounts can reveal useful clues about a person’s interests, relationships, work, travel, and financial concerns.

The attacker does not need a complete identity file. An employer, city, family relationship, recent trip, favorite investment topic, or trusted contact may be enough to make a message feel personal.
The FTC says scammers can use what people post, take over accounts to reach their contacts, or use advertising tools to target people by demographics, interests, and shopping behavior. That turns a mass campaign into a form of criminal performance marketing: obtain data, divide potential victims into groups, test a pitch, and concentrate effort where responses are strongest.
What targeted scams can look like
- A fake investment opportunity aimed at someone who regularly posts about cryptocurrency or markets.
- A fraudulent rental listing shown to people searching for housing in a particular city.
- A family-emergency request that uses public information about relatives.
- A business-email scam aimed at an employee who handles invoices, payroll, or wire transfers.
- A romance scam in which a fake persona is matched to a victim’s age, interests, and relationship status.
Profiling also explains why a message can feel uncannily specific even when the scammer does not know the recipient personally. The information may be incomplete or wrong—a joke can be mistaken for a genuine interest, or an old post can be treated as current—but a probabilistic guess only needs to work often enough to be profitable.
Warning signs
- A stranger references a recent post, event, purchase, or trip in unusual detail.
- A supposed bank, employer, government agency, or family member contacts you through a new channel.
- The request is urgent and asks for money, a password, a one-time code, or a change to payment details.
- An investment pitch follows engagement with financial content.
- The sender knows personal details but resists independent verification.
Do not treat personalization as proof of legitimacy. It may be evidence that information about you is public, exposed, or available through another compromised account.
2. Automating, scoring, and scaling the attack
Data analysis helps criminal networks decide what to do next at every stage. Systems can prioritize active email addresses, rank stolen credentials by likely value, identify victims who replied, test which scripts generate engagement, and route promising conversations to human operators.
ENISA’s 2025 threat landscape describes AI as an optimization tool for malicious activity and says large language models are being used to enhance phishing and automate social engineering. Europol likewise describes generative AI and large language models as tools that can improve social engineering and tailor messages to cultural context and personal details.
Examples include:
- Fake profiles that manage many conversations at once.
- Phishing campaigns that generate individualized messages instead of sending one generic template.
- Credential attacks that prioritize accounts likely to provide valuable access.
- Bots that identify successful account attempts and send the results to a human criminal.
- Automated lists that rank victims for follow-up investment, impersonation, or extortion.
This process is often hybrid rather than fully autonomous:
Rank #3
- Software collects and enriches data.
- A scoring system ranks targets or accounts.
- Templates or generative tools produce outreach.
- A human steps in when credentials, money, or system access is requested.
That division of labor can be more reliable than a claim that an “AI hacker” independently conducts an entire crime. Automation lowers the cost of contacting more people and lets criminals spend human attention only on the most promising cases.
Why scale changes the economics
Traditional spam wastes effort on people who never respond. Scoring reduces that waste. Even if a prediction is imperfect, a criminal operation can remain profitable when automated systems cheaply test thousands of targets and human operators focus on the smaller group that engages.
For organizations, the defensive response is to monitor behavior rather than search only for suspicious wording. Useful controls include rate limits, bot detection, login-anomaly monitoring, unfamiliar-device alerts, impossible-travel detection, risk-based authentication, phishing-resistant multifactor authentication, and independent payment approval.
3. Manufacturing trust with synthetic content and impersonation
Generative systems can produce convincing emails, chat scripts, fake profiles, voice clones, synthetic video, fake endorsements, and impersonations of executives, relatives, support agents, and public officials.
The FBI’s 2025 Internet Crime Report says AI-enabled synthetic content is becoming easier to create and harder to detect. It recorded AI-linked complaints involving business-email compromise, confidence and romance scams, and distress scams using cloned voices. The report’s $893 million figure is for complaints with an AI nexus; it does not mean that every loss was caused solely by a machine-learning model or generative-AI system.
Common examples
- A cloned executive voice tells an employee to transfer money immediately.
- A fake family member asks for emergency funds.
- An AI-generated profile builds trust before promoting an investment platform.
- A synthetic customer-support representative directs a victim to a fraudulent login page.
- A fake celebrity or influencer endorses a bogus investment opportunity.
The threat is not that synthetic media must be flawless. It only needs to be good enough for a rushed decision—especially when it is combined with real stolen information, delivered through a trusted account, or reinforced across several channels.
A real company logo, genuine email signature, familiar caller ID, or compromised account can create trust without any deepfake at all. That is why “look for signs that the content was generated by AI” is a weak standalone defense. Detection tools can produce false positives and false negatives, and polished language is no longer evidence that a message is legitimate.
Use independent verification
For payment requests, account changes, and urgent family emergencies, apply a second-channel rule:
- Do not use the phone number, link, or contact information contained in the request.
- Call a known number or contact the person through an established workplace or family channel.
- Require a second authorized person to approve business transfers.
- Use a pre-agreed code word for urgent family requests.
- Treat voice and video as evidence, not proof of identity.
4. Ranking and reselling stolen data
After a breach or account compromise, stolen information can be analyzed to determine what is most valuable. A username and password are more attractive when they work on corporate email, a financial account, a cloud service, or an administrator account. A customer database becomes more useful when it can be connected to payment, identity, or relationship information.

It also describes access brokers and criminal marketplaces that sell credentials, remote-service access, compromised corporate networks, and personal data.
Best Value
Criminals may prioritize:
- Corporate email and administrator accounts.
- Accounts with payment or cryptocurrency access.
- Healthcare and identity records.
- Credentials reused across several services.
- Access associated with wealthy individuals or influential organizations.
- Compromised mailboxes containing invoices, vendor relationships, travel schedules, or approval procedures.
This is more than a one-time data theft. The same information can create several revenue streams:
- Sell the raw data.
- Use it to take over an account.
- Use the compromised account to target its contacts.
- Use access to stage payment fraud, extortion, or ransomware.
- Sell the resulting access again.
That recycling creates compounding harm. One exposed password or mailbox can support attacks long after the original breach is forgotten.
Reduce the value of exposed data
You cannot always remove information once it has been copied, but you can reduce what an attacker can do with it:

- Secure email first because it often controls password resets.
- Enable MFA, preferably passkeys or hardware security keys where available.
- Revoke unused sessions, tokens, and connected applications.
- Review mailbox forwarding rules and OAuth grants.
- Separate administrator accounts from ordinary user accounts.
- Remove dormant accounts and rotate credentials after exposure.
- Store less personal information when it is not needed.
What consumers should do now
- Stop password reuse. Use a reputable password manager to generate and store unique passwords.
- Protect your email account. Enable MFA or a passkey and check recovery addresses, active sessions, forwarding rules, and connected apps.
- Secure financial and social accounts. Turn on login alerts and review recent activity.
- Verify urgent requests independently. Never approve a payment, password reset, or account change based on one unexpected message or call.
- Limit public signals. Avoid publishing travel plans, addresses, family identifiers, or detailed financial information where possible.
- Assume caller ID and media can be spoofed. A familiar voice, logo, profile, or number is not authentication.
- Monitor for identity misuse. Review bank alerts and credit reports; consider a credit freeze when identity exposure is plausible.
- Report quickly. Contact your financial institution and the relevant platform. In the United States, internet crime can be reported to the FBI’s IC3, while consumer scams can be reported to the FTC.
What businesses should do
- Require dual approval for wire transfers and changes to vendor payment details.
- Verify executive, vendor, and customer requests through an independent channel.
- Enforce MFA for email, VPNs, cloud applications, and administrator accounts.
- Use separate privileged accounts and remove dormant access.
- Monitor suspicious mailbox forwarding, OAuth permissions, unfamiliar devices, and impossible-travel events.
- Apply rate limits and bot controls to login and account-recovery workflows.
- Train employees with realistic impersonation and payment-fraud scenarios, not only generic phishing examples.
- Maintain a rapid response plan for compromised accounts, including session revocation, password rotation, payment recalls, and customer notification.
What the numbers do—and do not—prove
The FBI’s 2025 figures are reported U.S. complaint and loss data, not a complete global total. Many victims do not report because they are embarrassed, do not know where to report, or suffer business disruption and time loss that are difficult to measure. “AI-related complaints” also means the complaint had an AI connection; it does not establish that AI was the sole cause of each loss.
Similarly, the FTC’s $2.1 billion in reported social-media scam losses measures reports received by that agency, not every scam loss worldwide. The figure is still useful because it shows how social platforms can function as data-rich targeting and distribution channels.
The bottom line
Data science makes established crimes more efficient. It helps criminals find better targets, personalize ordinary phishing and fraud, automate follow-up, create synthetic trust, and identify which stolen accounts can be sold or exploited again. The strongest defenses do not depend on spotting a deepfake or judging whether a message “sounds like AI.” Unique credentials, phishing-resistant MFA, independent verification, account monitoring, and payment controls address the underlying problem: a criminal may know more about you—and act faster—than older scam defenses assumed.
