What we do

Leaked data research

To most users, Google is the gateway to exploring the internet. However, the deep web contains pages that cannot be indexed by Google. Within this space, lies the dark web — anonymized websites, often called hidden services, dealing in criminal activity from leaked data, hacking and human trafficking. Conducting security research on the dark web can be difficult. Website URLs on the dark web do not follow conventions and are often a random string of letters and numbers followed by the .onion subdomain. These websites require the TOR browser to resolve, and cannot be accessed through traditional browsers such as Chrome or Safari. In addition, traditional search engines such as Google do not exist in the deep web. Instead, website URLs are either exchanged person to person (online or in-person) or collected into a simple Html directory. This can make it difficult to find hacker forums deep web — specifically forums where serious individuals gather.

Cyber incident response

Your business is your top priority. At best, cyber attacks are a distraction. At their worst, they can cripple your operations. ATS has dedicated cyber incident responders in over 30 countries to help you quickly investigate cyber incidents and thoroughly remediate the environment, so you can get back to what matters most: your business. Our consultants combine investigative and remediation expertise with industry-leading threat intelligence and network and endpoint technology to help you with a wide range of activities — from technical response to crisis management.

Cyber security analysis

Performing a cyber security risk analysis helps your company identify, manage, and safeguard data, information, and assets that could be vulnerable to a cyber attack. Such analysis helps you identify systems and resources, determine the risk, and create a plan for security controls that can help protect your company.Perhaps you don’t know your risk level and the likelihood of a cybersecurity attack on your business, but it’s a real threat that’s impacting more companies every day and is therefore something you need to think about.

Penetration testing

Organizations can define penetration testing by what it is meant to assess. That includes all networks, applications, devices, and physical security components. It mimics the actions of malicious actors. Experienced cybersecurity experts leverage penetration testing to improve a company’s security posture and remove any vulnerabilities that leave it open to attack. When appropriately done, penetration testing goes beyond merely stopping criminals from unauthorized access to a company’s systems. It creates real-world scenarios that show businesses how well their current defenses would fare when confronted with a full-scale cyber attack.

Client cases

  • Slovak telecomunication operator

    We identified large exploited database stolen from Slovak telecomunication operator. We acquired sample data as a proof of concept and together with the operator and officials solved the problem.

  • Czech internet provider

    We found on the Dark web forum an offer where the attacker was trying to sell stolen databases, internal documents and several Access points to their servers from Czech internet provider. We helped the provider to identify the servers which were attacked. Also we managed the communication between the provider and the Office for personal data protection of the Czech Republic, so there was given no penalty.

  • Slovak bank

    Based on our Dark web research and analysis we detected a threat for a Slovak bank. Based on our cooperation with the bank we managed to protect their servers and databases.

  • Slovak energy company

    Our Dark web researchers discovered a vendor offering exploited databases, source code access and data from their customers. Based on our cooperation with the energy company we secured all possible access points and prevented the future incidents. Also we consulted the data breach with Slovak Office for personal data protection so the energy company was not fined and solved the problem with no harm.
