Defining Hybrid Networks and How to Secure it

Published

Written by John Madisson, EVP of Products and CMO at Fortinet

Organizations have distributed data and workloads across both cloud environments and on-premises data centers. As a result, IT teams have to deploy, manage, and secure increasingly complex and hybrid networks. And even though many organizations have moved many of their workloads into the cloud, the majority of them still operate hybrid environments.

Hybrid environments allow organizations to keep important data on-premises. This allows them to maintain full control over sensitive assets, while also taking full advantage of the scalability and agility the cloud provides. However, as organizations become more hybrid and distributed, their security needs to be able to span across all environments.

As applications, resources, devices, and workers work from anywhere, networks need to be able to adapt in real-time. Workflows now often span physical data centers as well as multiple cloud environments; applications follow users regardless of where they are connecting from or what device they are using, and data and other resources need to be securely accessed by any user on any device in any location. Security needs to be able to adapt and scale to meet these new requirements.

Five Essential Security Functions to Hybrid Networks
To properly protect and defend these hybrid environments, organizations should look for security solutions that provide the following critical functions:

  • Broad: Security solutions need to support a distributed security model where the exact same security solutions can be deployed in any environment.
  • Integrated: All of the various security solutions deployed across the network need to be able to see and work together as a single system to detect threats and respond to them in a coordinated fashion, regardless of where they occur.
  • Fast: These security functions need to operate not just at the speed of business, but at the speed of threats as well.
  • Automated: Anomalous and malicious behaviors need automated responses.
  • Security-driven Networking: Security-driven Networking weaves security and networking into a single, integrated system. This enables them to establish and enforce zero-trust access, dynamic network segmentation, and unified enforcement anywhere, on any device, in any location, without introducing security gaps or performance lags.

Success Requires Networking and Security to Function as a Single Solution
The majority of today’s security solutions are simply not fast enough, nor smart or responsive enough, don’t operate in enough places, and can’t adapt as quickly as today’s business requires. This is especially true in multi-vendor environments with disparate security solutions that don’t integrate when deployed. This lack of integration makes it impossible for organizations to securely use the flexible network environments they need to compete effectively.

Instead, these organizations need a security platform, like the Fortinet Security Fabric, designed to span, adapt to, and protect today’s dynamic environments. If they can’t, their business will not be able to keep up. And that is critical in today’s digital business environment, where the difference between success and failure can be measured in microseconds.

Positive Technologies Study Reveals Successful Cyberattacks Nett 5X Profits

Published

on

Positive Technologies has released a study on the dark web market, analysing prices for illegal cybersecurity services and products, as well as the costs incurred by cybercriminals to carry out attacks. The most expensive type of malware is ransomware, with a median cost of $7,500. Zero-day exploits are particularly valuable, often being sold for millions of dollars. However, the net profit from a successful cyberattack can be five times the cost of organizing it.

Experts estimate that performing a popular phishing attack involving ransomware costs novice cybercriminals at least $20,000. First, hackers rent dedicated servers, subscribe to VPN services, and acquire other tools to build a secure and anonymous IT infrastructure to manage the attack. Attackers also need to acquire the source code of malicious software or subscribe to ready-to-use malware, as well as tools for infiltrating the victim’s system and evading detection by security measures. Moreover, cybercriminals can consult with seasoned experts, purchase access to targeted infrastructures and company data, and escalate privileges within a compromised system. Products and tools are readily available for purchase on the dark web, catering to beginners. The darknet also offers leaked malware along with detailed instructions, making it easier for novice cybercriminals to carry out attacks.

Malware is one of the primary tools in a hacker’s arsenal, with 53% of malware-related ads focused on sales. In 19% of all posts, infostealers designed to steal data are offered. Crypters and code obfuscation tools, used to help attackers hide malware from security tools, are featured in 17% of cases. Additionally, loaders are mentioned in 16% of ads. The median cost of these types of malware stands at $400, $70, and $500, respectively. The most expensive malware is ransomware: its median cost is $7,500, with some offers reaching up to $320,000. Ransomware is primarily distributed through affiliate programs, known as Ransomware-as-a-Service (RaaS), where participants in an attack typically receive 70–90% of the ransom. To become a partner, a criminal must make a contribution of 0.05 Bitcoin (approximately $5,000) and have a solid reputation on the dark web.

Another popular attack tool is exploits: 69% of exploit-related ads focus on sales, with zero-day vulnerability posts accounting for 32% of them. In 31% of cases, the cost of exploits exceeds $20,000 and can reach several million dollars. Access to corporate networks is relatively inexpensive, with 72% of such ads focused on sales, and 62% of them priced at under a thousand dollars. Among cybercriminal services, hacks are the most popular option, accounting for 49% of reports. For example, the price for compromising a personal email account starts at $100, while the cost for a corporate account begins at $200.

Dmitry Streltsov, Threat Analyst at Positive Technologies, says, “On dark web marketplaces, prices are typically determined in one of two ways: either sellers set a fixed price, or auctions are held. Auctions are often used for exclusive items, such as zero-day exploits. The platforms facilitating these deals also generate revenue, often through their own escrow services, which hold the buyer’s funds temporarily until the product or service is confirmed as delivered. On many platforms, these escrow services are managed by either administrators or trusted users with strong reputations. In return, they earn at least 4% of the transaction amount, with the forums setting the rates.”

Considering the cost of tools and services on the dark web, along with the median ransom amount, cybercriminals can achieve a net profit of $100,000–$130,000 from a successful attack—five times the cost of their preparation. For a company, such an incident can result not only in ransom costs but also in massive financial losses due to disrupted business processes. For example, in 2024, due to a ransomware attack, servers of CDK Global were down for two weeks. The company paid cybercriminals $25 million, while the financial losses of dealers due to system downtime exceeded $600 million.
