Due to the rapid expansion of web applications, new attack vectors are emerging everyday, that malicious hackers can use for their personal gains to the detriment of your business.

Each penetration test can be performed via black, grey or white box method. Black box testing is ideal for simulating real world threats when attacker has zero information about the targets, while white box approach can potentially find more vulnerabilities by utilizing all the knowledge of inner workings of all the services behind the web resources unavailable to outsiders.

Web application penetration testing is comprised of several main phases:

  1. Pre-Engagement: define client goals, legal documents preparation and NDA signing.
  2. Reconnaissance: information gathering via OSINT and passive observation without any disruptive actions.
  3. Analysis: evaluate collected data, select targets, choose attack vectors and prepare penetration strategies.
  4. Exploitation: attempt to compromise and gain control over selected targets, disrupt vulnerable services.
  5. Reporting: document every step taken with detailed explanations and screenshots.
  6. Remediation: provide instructions on fixing found vulnerabilities, assist on every step of their implementation.
  7. Verification: check every previously detected vulnerability for implemented patches.

Compromised web applications by malicious parties can result in, but not limited to:

  1. Stolen private/confidential data.
  2. Malware infection and further spreading to connected devices (users/employees) or participating in other illicit activities.
  3. Deletion/corruption/encryption of critical data with a ransom demand.
  4. Denial-of-Service.
  5. Increased hosting fees, or degraded performance due to installed crypto-miners or other resource-intensive malware.

These and many other post-exploitation scenarios can not only stop your business activities, cost a lot of money to recover from, but also decrease your customers' trust and potentially reduce search engine ranking score due to reduced domain authority or even blacklisting.

Performing penetration testing at least every year should be part of your security strategy, that will prove cost-effective in the long run.


Wireless network penetration testing involves identifying and trying to gain access to internal network via weak WiFi security, examining the connections between all devices connected to the business’s network. These devices include workstations, laptops, tablets, smartphones, webcams, and other internet of things (IoT) devices.

Wireless penetration tests are usually performed on the client’s site, as the pentester needs to be in physical range of the wireless signal to audit it.

It is comprised of several main phases:

  1. Pre-Engagement: define client goals, legal documents preparation and NDA signing.
  2. Reconnaissance: information gathering of available wireless networks and their security.
  3. Analysis: evaluate collected data, select target access points, choose attack vectors and prepare penetration strategies.
  4. Exploitation: attempt to gain access to wireless network, degrade/disrupt performance.
  5. Reporting: document every step taken with detailed explanations and screenshots.
  6. Remediation: provide instructions on fixing found vulnerabilities, assist on every step of their implementation.
  7. Verification: check every previously detected vulnerability for implemented patches.

Compromised wireless networks by malicious parties can result in captured/phished credentials giving attackers access to numerous internal and external services, which can lead to but not limited to:

  1. Compromise of business infrastructure such as web applications, databases, mail servers, and other critical services.
  2. Stolen private/confidential data.
  3. Malware infection and further spreading to connected devices (users/employees) or participating in other illicit activities.
  4. Deletion/corruption/encryption of critical data with a ransom demand.

Physical penetration testing simulates a real-world threat scenario where a malicious actor attempts to circumvent physical barriers to gain access to infrastructure, buildings, systems. The goal of a physical penetration test is to detect weak points in corporate overall physical defenses and mitigate them.

Physical penetration testing is comprised of several main phases:

  1. Pre-Engagement: define client goals, legal documents preparation and NDA signing.
  2. Reconnaissance: map the physical location of defense mechanisms, such as cameras, gates, guards, and many other physical security mechanisms.
  3. Analysis: evaluate collected data, choose attack vectors and prepare physical penetration strategies.
  4. Exploitation: attempt to enter the building, access server rooms via lock picking or social engineering, intercept EM waves, clone RFID tags, plug backdoors into poorly protected wires/cables, get access to sensitive information and equipment.
  5. Reporting: document every step taken with detailed explanations and screenshots.
  6. Remediation: provide instructions on fixing found vulnerabilities, assist on every step of their implementation.
  7. Verification: check every previously detected weak links in physical security.

Social engineering focuses on the weakest link in any security system - people. These tests usually include phishing, USB drops, or impersonation. The goal of social engineering is to exploit weaknesses in humans to gain access to information or systems they possess.

Social engineering is comprised of several main phases:

  1. Pre-Engagement: define client goals, legal documents preparation and NDA signing.
  2. Reconnaissance: information gathering of current, former employees, their contacts and interests, social accounts, and many other personal data.
  3. Analysis: evaluate collected data, select targets, choose attack vectors and prepare social engineering strategies.
  4. Exploitation: attempt to trick the target into giving out confidential information, open an email attachment, access specifically crafted websites, plug in dropped USB drives, and many other techniques.
  5. Reporting: document every step taken with detailed explanations and screenshots.
  6. Remediation: provide instructions on how to train your employees to not fall for social engineering attacks.
  7. Verification: conduct testing again to determine the result.

Tricked employees via social engineering by malicious parties can result in, but not limited to:

  1. Stolen/rerouted payments and private/confidential data.
  2. Compromise of business infrastructure such as web applications, databases, mail servers, and other critical services.
  3. Malware infection and further spreading to connected devices (users/employees) or participating in other illicit activities.

Incident response is an act of handling and recovering from security incidents, breaches, and cyber attacks. A well accomplished incident response can effectively identify the problem, minimize the damage, and reduce the cost of a cyber attack, while finding and fixing the cause to prevent future attacks.

When a security incident occurs, every second counts. Malware infections will spread rapidly, infecting as many machines as possible, ransomware will cause enormous loses and damage, and compromised accounts can be used for further access and privilege escalation, leading attackers to more sensitive assets.

Incident response is comprised of six main phases:

  1. Preparation: Follow the incident response plan, if present. Every company should have one prepared beforehand. Otherwise, we can prepare one for you, after we neutralize the incident.
  2. Analysis: detect a breach by analyzing logs, assess damage and prepare for damage minimization.
  3. Containment: prevent further penetration and isolate vulnerable systems.
  4. Eradication: neutralize the threat and clean affected systems.
  5. Recovery: recover as much damage as possible and resume normal business operations.
  6. Post-Incident Report: document the incident, compile a report and propose further steps to prevent future attacks.

Digital forensics uses scientifically derived and proven methods toward the preservation, collection, validation, identification, analysis, interpretation, documentation and presentation of digital evidence derived from digital sources for the purpose of facilitating or furthering the reconstruction of data and events.

We specialize in data recovery from affected systems due to a cyber attack.

The following steps are taken for successful extraction of data:

  1. Identification: the type of incident and digital media is identified.
  2. Preparation: selection and preparation of tools, techniques, search warrants (if required).
  3. Planning: development of a procedure that will maximize collection of untainted evidence/data.
  4. Preservation: isolation, securing and preserving of the state of physical and digital evidence/data.
  5. Collection: recording of the physical scene and duplicate digital evidence using standardized and accepted procedures and tools.
  6. Examination: systematic search of evidence collected (if required).
  7. Analysis: determination of the significance of evidence, reconstruction of data fragments and drawing conclusions based on evidence found (if required).
  8. Presentation: written summary and report of the work done.
  9. Finalization: return of physical and digital property to client.

Ransomware is a malicious program that blocks access to your data by encrypting the contents of files or drives. The message is usually presented to the user, asking for a payment in exchange for a decryption key to your files. Unless the payment is made, the data will be permanently lost, but this is not always the case. Some ransomware programs use outdated or broken encryption, enabling decryption without the payment. However, in many cases, ransomware encryption is unbreakable and the only option is to pay the ransom, usually in cryptocurrency.

If your computer is infected with ransomware, we can help you restore the affected data in several ways:

  1. Determine ransomware type: In some instances data is recoverable via an alternative method. Our engineers will analyze your unique situation to determine the safest and most cost-effective option for restoring your important files.
  2. Data decryption: We will determine whether a decryption key exists for your ransomware infection or if one can be created. If decryption is possible, we can perform the process safely and quickly, returning your systems to a functional state as soon as possible.
  3. Ransom management: As a last resort, if there is no alternative route to recover your files, we will manage the whole process, simplifying sometimes complicated steps to obtain and transfer cryptocurrencies, and without providing the malware creator with your personal information.

Some ransomware strains will put you on a clock, when upon expiration the payment amount will increase or even make your files unrecoverable. So we suggest you contact us as soon as the incident occurs.
