How Stolen Cookies Compromise Online Retail Security

The security threats that online businesses face are growing more sophisticated each day. According to UK government data, 50% of businesses had some form of breach or attack in the last 12 months.

Protecting websites and data is key for online retailers that rely on digital channels. Something as simple as a session cookie can be a vulnerability.

Understanding Cookie Hijacking

Some refer to it as cookie hijacking, others call it session hijacking. Both involve session cookies – temporary files that authenticate users during active sessions on websites.

Hijacks happen when an attacker intercepts these cookies to take control of a legitimate user’s session. They can then assume the user’s identity, exposing both customer and company data. There’s also the risk of unauthorised actions on customer accounts.

Cybercriminals can use various methods to hijack and steal cookies. Phishing attempts, malware infections, and man-in-the-middle attacks are some of the most common.

What Are the Risks for Retail Businesses?

Session hijacking can impact both customers and companies alike. These attacks may result in:

• Financial losses: Attackers can commit financial fraud with access to a live web session. Unauthorised purchases may affect account holders first. But online retailers will ultimately pay the price.
• Reputational damage: Security breaches can erode customer trust, driving shoppers to competitors. That means lower chances of repeat sales and dampened customer loyalty.
• Operational disruptions: It’s all business as usual until it isn’t. A session hijack and exposed customer or company data can wreak havoc on your operations.

How Can Online Retailers Prevent Session Hijacking?

There are a few dedicated solutions to help prevent session hijacking. Until you find the solution that’s right for you, there are simple ways to boost your and your customers’ protection as a start:

• Have secure socket layer (SSL) certificates on all websites: These encrypt the data transmitted between your site and its users. This helps stop the interception of sensitive information such as session IDs.
• Encourage the use of multi-factor authentication: Accounts with extra layers of protection are far harder to hack. Attackers will need more than just login credentials.
• Educate customers and staff: Highlight phishing techniques to make any attempts more noticeable. Informing account holders about the benefits of multi-factor authentication can increase uptake.
• Keep all systems and software up to date: Update all back-end systems to the latest versions to patch vulnerabilities. Outdated software is more exposed to security flaws.

Stop Session Hijacking Before It Happens

The larger your online retail business, the larger the target painted on your back. Heed the lessons above and take steps to stop cookie and session hijacking before it’s too late.
