5 reasons why web security is crucial to avoid ransomware attack

Web vulnerabilities are a key part of many ransomware attack chains, even those that start from a phishing email. This post puts together five reasons why eliminating web vulnerabilities is vital to prevent ransomware attacks.

Ransomware has caused significant issues for organizations globally in recent years. In response, many have focused their efforts on defending against this type of threat by redirecting their budgets away from web security. Regrettably, this approach actually makes their IT systems more vulnerable to ransomware.

A ransomware attack is the result, not the attack

A successful attack yields various outcomes, and one of them is ransomware. Do not mistake it for the attack itself.

Think of a ransomware attack as an illness. The ransomware software acts like a virus or bacterium, spreading and infecting the entire system once it has entered. Preventing its entry is key to avoiding the harmful effects.

Just as hosts transmit bacteria and viruses, someone needs to introduce ransomware into a system. In both cases, prevention is better than cure, so your most effective defensive measures are those that prevent ransomware from entering your systems in the first place.

Cybercriminals can deliver ransomware through various means, including phishing, social engineering, or exploiting system vulnerabilities, many of which are web vulnerabilities. Thus, defending against web vulnerabilities should be the first line of defense.

“Preventing attacks that can deliver ransomware is the only way to safeguard your organization from it. Once ransomware has infiltrated your systems, it becomes too difficult to stop.”

Ransomware spreads through web-based attacks

Many consider phishing and social engineering as the most common methods for delivering ransomware. However, the success of phishing attempts often relies on prevalent web vulnerabilities such as cross-site scripting (XSS). If these exist, attackers can manipulate users and employees into trusting their fake messages by using the victim’s trust in the business and domain name.

For example, an attacker could utilize a web application with an XSS vulnerability to send employees a phishing message containing a malicious URL with the company’s domain name. When the employee visits the vulnerable page, it redirects them to a malicious site that triggers the browser to download a ransomware installer. This type of attack is highly convincing and even the most cautious employee may fall for it.

Moreover, attackers could leverage vulnerable web applications to target business partners, customers, or even the public, potentially exposing the company’s security weaknesses and tarnishing its reputation.To minimize this risk, it’s essential to ensure that all sites and applications under the company’s domain name are free of XSS vulnerabilities.

“Web vulnerabilities in your sites and applications can enable phishing attacks against your organization, partners, clients, or the general public, potentially causing permanent damage to your reputation.”

Business is moving to the cloud – and so are cybercriminals

As mentioned earlier, there are multiple methods to deliver ransomware, and many exploit vulnerabilities. Previously, the most attractive vulnerabilities were found in on-premises systems such as outdated software or misconfigured devices leading to network security issues. With the shift to remote work due to the pandemic, on-premises systems have become less significant.

On-premises networks and infrastructure are being replaced by cloud solutions that rely heavily on web technologies, making web vulnerabilities increasingly important in terms of security. Issues that once only impacted marketing websites now pose a threat to business-critical systems and data.

Cybercriminals are also adapting to changes and recognizing that the traditional method of infecting physical desktops and servers through a local network may not be effective anymore. With many users accessing cloud-stored data through their web browsers, cybercriminals are shifting towards exploiting web and cloud vulnerabilities to ensure that their ransomware can reach the data.

“With the shift to cloud solutions, the importance of web security has grown while local network security has become less relevant. Neglecting web security in favor of network security leaves vulnerabilities open for attackers to exploit.”

Ransomware victims do not report their attack details

Many organizations that fall victim to a ransomware attack keep the details private, which hampers the development of effective protection methods and negatively impacts global IT security. Such confidentiality may be due to the inability to quickly locate and fix security weaknesses, the fear of exposing the organization to further attacks or the belief that admitting security errors will harm reputation. However, this behavior only exacerbates the problem. It’s like a country with a deadly virus withholding information for political reasons.

“Keeping quiet about the methods used to deliver ransomware attacks only hinders the ability of the wider community to protect itself from future ransomware attacks.”

Media reports focus on incidents, not solutions

A lack of technical information in media reporting on ransomware attacks impedes progress in defense against ransomware. Major enterprises like Cloudflare, which follow best practices for incident disclosure and provide detailed information on security incidents, offer a positive example for other organizations to follow. If more victims of ransomware attacks adopted these practices, it would benefit the global community’s efforts to combat ransomware.

“To improve global cybersecurity, it is crucial that all relevant details of ransomware attacks are widely disseminated. Sharing this information allows the community to better protect itself against similar threats in the future.”
