How to Prevent Account Hijacking?

Accounts are the backbone of every business. Users need them to operate across the organizations, do file exchanges, and interact with others. It’s a communication web; networks cannot be set up without accounts. Unfortunately, administrator accounts are not the only ones susceptible in organizations.

Hackers target ordinary users and attempt to escalate their privileges. You can call hijacking the act of taking over something. This guide will provide an overview of the concept and tell you how to prevent account hijacking.

What is Account Hijacking?

Account hijacking occurs when someone invades your user account by accessing your application. Once they can access the account, they can publish content in your name, commit fraud, or impersonate you. Account hijacking is one of the fastest ways to cause severe damage and exploit vulnerabilities across infrastructures.

The Consequences of Account Hijacking

Account hijacking has many consequences, including being hacked and accessed by an unauthorized individual. Hijacked accounts are a gateway to sensitive data and can leak trade secrets about organizations, customers, employees, and other proprietary information.

Businesses can permanently lose valuable information and expose it to unauthorized parties. Account hijacks have financial costs; some losses from paying ransoms can amount to millions. Your organization will also face many regulatory fines and penalties, and significant recovery costs, including system repairs, will be involved.

Account hijacking can damage an organization’s reputation and image. Customers and partners will lose faith and confidence in the firm’s ability to protect itself.

This will result in lost business opportunities, and new clients might move away from your brand. Hijacked accounts also cause operational disruptions and impact business continuity. They can delay projects, affect workplace productivity, and lower morale.

How Does Account Hijacking Work?

It’s essential to remember that account hijacking is not the same as account fraud. In hijacking, the hacker takes over your social media profiles, corporate handles, session logins, and any other credentials you possess. They use those details to log in to your respective platforms, wherever you are active. Account fraud is creating a fake profile that mimics your original identity.

In account hijacking, when an attacker compromises your account, they can move laterally through your network and launch further attacks.

Standard Methods Used in Account Hijacking Attacks

Account hijacking can use a mix of different techniques to compromise user accounts. Some of them are:

Phishing

Phishing occurs when users accidentally give out their credentials by interacting with malicious emails. These emails often appear to come from legitimate sources and include proof enough to convince the victim that they are interacting with the right person. In phishing, the attacker might manipulate the victim into making unauthorized financial transactions or even impersonate legitimate services via phone numbers or fake websites.

Social Engineering

Social engineering is when the attacker gets into the mindset of the victim and manipulates them by tapping into their emotion. They might get the victim to trust them, open up, and share sensitive information. Social engineering could also use scare tactics, fear, and other negative emotions, which might jolt the victim into taking immediate action.

Man-in-the-Middle Attacks

These are attacks where the attacker will compromise communications between two parties and eavesdrop on their sensitive data exchanges.

Credential Stuffing

Credential stuffing attacks occur when attackers use automated tools to generate many user password combinations. These combos are generated from previous data breaches and use a guessing technique. Credential stuffing works best for users who commonly reuse passwords across multiple websites and apps. So, if one account can be cracked, the others will be compromised since they use similar passwords.

There is no need to hack into the environment; once an attacker figures out the password, they can log into your account instead.

Malware and Trojans

These can involve keyloggers that record your keystrokes when you type sensitive information. If your device is impacted and you engage with a malicious web form you aren’t aware of, the k; their malware can steal your sensitive information without your knowledge.

How to Detect Account Hijacking Attempts?

Here are some warning signs you should look for to determine whether your account is being hijacked.

• Weird login activities—Pay close attention to suspicious logins in your network. These may include unexpected logins from unknown geolocations or devices or logging in at unusual hours of the day that don’t match your employees’ standard usage patterns.
• Unusual email movements – If the emails in your inbox suddenly get deleted or go missing, you know something is up. Look for cases where your read emails are moved to the spam folder or other folders. If you didn’t approve these changes, someone else is doing it.
• Account recovery requests—You may receive repeated account recovery requests. Someone may send you the OTP to your phone and lure you into divulging sensitive information. If you didn’t issue a recovery request, be wary.
• Unverified IP addresses—It’s a dead giveaway if unverified IP addresses attempt to communicate with your cloud services or connect to the organization’s networks.

Best Practices to Prevent Account Hijacking

Protecting your organizations with multi-layered phishing protection can prevent account hijacking attacks. Teaching your employees to recognize the signs of an incoming attack is also crucial.

They should know what to say to adversaries and what not to say. Being aware of the latest social engineering practices can boost their confidence. They will learn how to handle incoming threats and neutralize them whenever they attempt to engage with them.

Use continuous threat detection and monitoring technologies to detect signs of account misuse, inactivity, and suspicious behaviors. AI-based threat detection can monitor your endpoints around the clock and immediately alert you if it detects anything wrong. Endpoint protection tools can also prevent account hijacking by continuously monitoring your endpoints, assets, users, and IoT devices.

Consider hiring security experts outside of using automation tools who can give you human reviews occasionally. They will tell you whether your security strategy is working as intended or if it needs areas of improvement.

Tell your employees to rotate their passwords regularly and not use the same password everywhere. Implementing proper cyber hygiene practices and not sharing sensitive information with strangers online is also essential.

Organizations today are encouraged to adopt advanced practices that go beyond the traditional security solutions identified above. One key focus area is implementing a Zero-Trust framework. This step reduces the chance of unwanted access by viewing each access attempt as untrusted and constantly authenticating it. Even when malicious actors surpass initial protective measures, Zero-Trust helps curtail lateral movement and compartmentalize potential damage.

Another important innovation is the application of machine learning-based behavioral analysis. These systems monitor user behavior in real-time and look for irregular patterns that could suggest hijacking attacks. For example, abrupt alterations in login IP addresses, uncommon access times, or deviations from defined user profiles can generate instant alerts, allowing for immediate incident response. Combining such analytics with practical Security Information and Event Management (SIEM) solutions further enhances monitoring and response capabilities.

Regular security awareness training is also required. Periodically, simulated phishing campaigns and updated training modules enable employees to identify and counter social engineering methods easily. Coupled with strict password policies, multi-factor authentication, and biometric identification, these training modules strengthen security habits.

Real-World Examples of Account Hijacking

Account hijacking doesn’t stop at stealing login credentials. Thieves have no honor, and they will steal phone numbers, too. SIM-swapping crimes have increased since 2021, and the FBI says that port-out hijacking incidents are under review.

Storm-0501 is one of the best stories of account hijacking in the real world. Ransomware attackers hopped from on-premises systems to the cloud to compromise Microsoft 365 user accounts. They launched high-profile ransomware-as-a-service attacks and compromised targets, exploiting weak credentials and overprivileged access rights. They gained control over the whole network and created persistent backdoor access to cloud environments.

The threat actor was active for over three years and riddled target organizations with ransomware streams like Blackhat, Lockbit, Hive, etc. They even dropped the Embargo ransomware and performed network reconnaissance to identify high-value assets.
