7 Things A Cyber Criminal Could Do With Your Data

With the growing reliance on digital services, cybercriminals now have more opportunities to target individuals. An estimated 5.9 billion accounts were compromised in data breaches recently.

Although it's concerning to imagine our data being misused, knowing what types of information a cybercriminal seeks and understanding their methods can help us safeguard our assets.

What Types Of Data Does A Cyber Criminal Target?

• Personally Identifiable Information (PII) - data that can be used to identify, contact, or locate someone, including names, addresses, birth dates, email addresses, and phone numbers.
• Financial Information - Consists of credit card numbers, banking information, insurance details, billing accounts, and other data related to financial activities.
• Healthcare Data - Information used for medical services such as hospital records and medical insurance.
• User Credentials - Online credentials including usernames, email addresses, passwords, and online shopping login details.

What Can A Cybercriminal Do With Your Information?

1. Sell Your Data

Many cybercriminals don't use the stolen data themselves—they sell it instead. A common marketplace for this is the dark web, where collections of stolen data, sometimes containing millions of records, are sold.

For instance, stolen PayPal account details with a minimum balance of $1,000 can fetch around $20. You can check out this index to see estimated prices for various types of data.

2. Hold Your Data For Ransom

Known as a ransomware attack, cybercriminals gain unauthorised access to an organisation’s system and encrypt crucial data, only returning access after a ransom is paid.

This type of attack has been increasing and significantly impacts the market, with damages exceeding $30 billion in recent years.

3. Carry Out An Account Takeover

By using stolen login credentials like your username and password, cybercriminals can access your online accounts and change the passwords to lock you out.

Hackers can target any kind of account, from social media to Amazon. However, they often aim for accounts that include payment details to exploit your financial information.

4. Create Targeted Phishing Attacks

Stealing data is often just the first step in a broader strategy.

Some cybercriminals use stolen data to target individuals or organisations with personalised fraudulent emails, making the victim believe they are a trusted source.

‘Whaling’ is a specific type of phishing attack that targets senior executives, potentially offering a large payoff to criminals.

5. Carry Out Identity Fraud

Identity fraud occurs when cybercriminals use someone else's identifiable information for their gain. If a threat actor collects enough data about an individual, they can:

• Complete fraudulent purchases for products or services
• Apply for financial accounts, such as credit cards
• File fraudulent tax returns and income tax refunds in your name
• Rent an apartment or apply for a job using your identity
• File for government benefits
• Apply for a driver’s licence or passport

6. Hire Out Your System As A Botnet

If cybercriminals gain access to your systems, they can connect your IT to a botnet—a network of hacked computers and servers.

This powerful network enables criminals to perform large-scale crimes, such as DDoS attacks, which sabotage a website by overwhelming it with requests, rendering it inoperative.

7. Steal Infrastructure

As servers and storage systems can be expensive, some cybercriminals ‘borrow’ others’ infrastructure.

They attempt to break into your systems to store their data and run applications on your infrastructure, avoiding the costs of their own resources.

How Can You Prevent Cybercriminals From Accessing Your Data?

Given the high level of cyber risk, it is crucial for both consumers and businesses to protect their personal information.

Here are some key practices to incorporate into your routine:

• Use strong and unique passwords, with a mix of numbers, letters, and symbols. Avoid using the same password across multiple accounts to prevent hackers from accessing all of them if one is compromised. Make sure each account has a distinct password.
• Set up two-factor authentication to stop unauthorised access, even if your login credentials are stolen.
• Shred documents containing personal information before disposal.
• Install up-to-date antivirus software on your devices.
• Be cautious of public Wi-Fi, and avoid accessing accounts or sending documents with sensitive personal data.
• Stay alert to inbound emails or texts asking you to click a link or share personal information, and always double-check their authenticity.
• Protect your digital communications with a secure email solution like Mailock.

Conclusion

Understanding the ways cybercriminals exploit data is crucial.

By knowing the types of information they target and their methods of misuse, we can better protect ourselves and our data.

Simple practices like using strong, unique passwords, enabling two-factor authentication, and staying vigilant against phishing attempts can make a significant difference in securing your digital life.

At the end of the day, staying informed and proactive is your best defence against cyber threats. Stay safe and keep your data secure!
