At the same time, hackers are taking advantage of this power to do malicious things. For example, when a website is compromised, hackers are able to inject scripts into websites to steal sensitive information. Unlike a traditional defacement, such scripts do not result in any visible differences in the content of a webpage.
In a traditional defacement, changes are often very visible, and images like these are probably what comes to mind:
However, once a hacker has managed to hack into a website, the hacker can do much more than just make a statement.
In recent years, there has been an increase in cases where the hacker would rather stay hidden and exploit the site for monetary gains instead.
Card Skimming (Magecart)
Major websites that have been affected by such attacks include British Airways, Ticketmaster, Forbes, Newegg etc.
A popular platform for setting up e-commerce sites is known as Magento. Hackers have been busy exploiting vulnerabilities in unpatched Magento sites to steal the payment information. As such, the term “Magecart” has been coined as a general term for such attacks.
How it works
Often, to avoid arousing suspicion, hackers will try to use a domain name that appears similar to the website, like this script that was found on British Airways’ site.
When users try to checkout on the page, everything appears to work normally. However, in the background, the user’s payment information is captured and sent to the hacker.
A quick primer on cryptocurrency mining: Cryptocurrencies like Bitcoin, Ethereum and Monero do not have a central authority to verify transactions, but instead use large amounts of computing power to verify cryptocurrency transactions. To incentivize users to contribute computing power for this purpose, users who contribute their computing power get paid a small amount of that cryptocurrency. This process of contributing computing power in return for cryptocurrency is called “mining”.
This requires paying for computing resources (and the required electricity) and thus hackers try to make use of other people’s resources instead, such as unsecured cloud environments.
It was reported in Symantec’s Q2 2020 Threat Landscape update that browser-based cryptojacking had increased 163%, coinciding with the increase in value of cryptocurrencies.
How it works
The hacker adds a cryptomining script to the website in which any currency earned goes to the hacker. The script remains hidden as visitors browse the website, but uses the visitor’s computing power to perform cryptocurrency mining in the background.
Such scripts tend to heavily tax the computer’s CPU, leading to slowdowns, heat and noise on the visitor’s computer, and thus dissatisfaction and loss of trust among website visitors.
How the new WebOrion® JME counters such attacks
With this engine, if a known malicious script is found, you are informed about the existence of the script, as well as the name of the threat given by the antimalware community, from which you can research to find out more. With this information, you can understand and respond to threats faster.
An additional benefit that the JME has, is that it does not require a baseline of what the website should be like. Therefore, you can use this engine on websites that are extremely dynamic.
However, such scripts can cause reputational harm to your website and brand, or even lead to financial losses being incurred by your customers.
