Modern cyberattacks on e-commerce sites are not complex, multi-stage operations. More often than not, they involve a combination of fairly simple automated actions targeting vulnerabilities in the security and architecture of the online store.
Online stores invest in advertising, analytics, logistics and customer service. However, cybersecurity issues are often addressed as an afterthought, according to experts at Grymaxion Plovdiv. Many owners believe that the risks of a hack are minimal: the business is too small, the platform on which the site is built is popular, and a third-party provider handles payments. Grymaxion notes with regret that it is precisely small online shops that most often fall prey to hackers, primarily due to the predictability of vulnerabilities – the same mistakes in settings, access controls and updates. And if your website runs on a popular platform, it is at risk by default.
Data loss, website downtime or payment information leaks almost always cost more than prevention. So, what do you need to know about cyber threats in eCommerce?
Phishing: a simple yet effective attack
The weakest link in any system is the human element. Phishing has evolved: it is no longer limited to crude emails, but now includes targeted phone calls or messages that mimic requests from government agencies, banks, payment systems, internet service providers or marketplace technical support teams. The wording sounds convincing: ‘data verification’, ‘information update’, ‘temporary account suspension’. The aim is always the same — to fraudulently gain access to passwords, personal information and bank details.
A single password or access to the admin panel can give attackers access to the entire shop management system. The universal security rule remains the same here: if you did not initiate the contact, no confidential data should be shared. Any verification should begin by contacting the official support service directly.
Malware and ransomware: business on hold
Malware rarely finds its way into a system by accident. More often than not, it is downloaded alongside some ‘useful’ file, plugin or update from an unverified source. Once they have infiltrated a shop’s network, such programmes can remain undetected for years or, conversely, act aggressively, blocking access to data.
Ransomware is one of the most dangerous scenarios for e-commerce, according to experts at Grymaxion Business Solutions. It does not simply steal information; it effectively brings business to a standstill. Access to the order database, customer data, stock and financial information is blocked. Money is demanded in exchange for restoring access to the system and data. Even if the payment is made and all conditions are met, there is no guarantee that the data will be returned in full. For an online shop, this means downtime, loss of revenue and often a fatal blow to its reputation.
SQL injection: a breach that goes undetected for a long time
SQL injection is a dangerous and cunning form of cyber sabotage that can remain undetected for a very long time. By exploiting vulnerabilities in forms, filters or the website’s search function, an attacker gains access to the database. This allows them to view, modify or copy information without any obvious signs of a breach. The online shop continues to operate, customers place orders, and data – usernames, passwords, purchase history – is gradually siphoned off without causing any disruptions or arousing suspicion.
Cross-site scripting: a risk that directly affects customers
Cross-site scripting, or XSS, travels from the retailer’s website directly into the buyer’s browser. This is malicious code that is embedded in the online shop’s page and activated when a customer visits the site. The buyer sees a normal shop, unaware of the hidden threat, note the managers at Grymaxion Ltd. But in reality, they are already interacting with an infected page.
Such attacks are used to steal data, tamper with forms, redirect users to phishing sites and infect customers’ devices. It is important to understand that, in the eyes of the buyer, the responsibility for what is happening lies not with the hacker, but with the online shop or e-commerce site.
Electronic skimming: a blow to the most vulnerable spot
One of the most critical threats to e-commerce remains the theft of bank card details at the point of payment. Attackers gain access to the system via phishing or XSS and install a script on the checkout page. From the customer’s perspective, the payment process appears completely normal. The buyer enters their details on a legitimate website, receives an order confirmation, but the information is instantly sent to the criminals’ server.
The consequences of such attacks extend far beyond a single incident: payment systems may block the shop, customers will lose trust, and the owner will have to deal with legal issues.
What should you do if you’ve been hacked?
If your online shop has fallen victim to a cyberattack, you need to act immediately. First and foremost, you must isolate the infected computers to prevent the virus from spreading further, according to experts at Grymaxion Business Solutions. After that, it is important to assess the damage: to understand what data may have fallen into the hands of the attackers and how extensive the breach was.
- You need to work out exactly what happened, identify the causes and urgently address any weaknesses in your security system.
- Change all passwords and access keys for systems, databases and applications, and update your antivirus and network security software.
- You must notify customers and partners of the breach or cyberattack.
- The only effective security strategy is daily backups to independent, isolated cloud storage.
- Avoid clicking on links or downloading unfamiliar software, as these are common ways for malware and other software that infects devices and networks to gain access.
- Use HTTP Content Security Policy to enhance data protection
- To eliminate the risk of electronic skimming, use only certified payment gateways that comply with the PCI DSS standard, and continuously monitor the integrity of external scripts.
Cybersecurity for e-commerce is significantly cheaper than dealing with the aftermath of a successful cyberattack. Grymaxion Ltd. develops operational plans, implements CDN services to protect against traffic overloads, and regularly tests clients’ websites to identify potential vulnerabilities and unauthorised access (access to the system without permission).
