Professional investigation and response

Cybersecurity incident investigation

  • Provide emergency response suggestions and incident investigation services for various types of incidents, such as APT, AD hacks, WebShell, backdoor programs, ransomware, data breaches, compromised equipment, etc.
  • Identify the root cause of the incident, compromised hosts, and provide the mitigation suggestions.

System / Web / AP log analysis

  • Find out the source of attacks and attack patterns

Malware analysis

  • Sandbox and professional manual analysis on provided malware sample.

Service Process

Service Process

  • Preparation

    - Clarify incident status - Identify customer’s requirement - Emergency containment suggestions - Provide IR plan

  • Detection

    - Endpoint scan (ThreatSonar) - Collect and analyze critical evidence - Identify the compromise scope

  • Investigation and response

    - Survey sampling - Sample analysis - Log analysis - Threat hunting - Identify root cause - Containment recommendations

  • Response

Use Case

Advanced persistent threat attack incident

Advanced persistent threat attack incident

  • Attack methodUse zero-day or N-day vulnerabilities, network penetration tools (Cobalt Strike), customized backdoor attacks (NT 5.x NDIS driver backdoor, Webshell, etc.) and network VPN agents (softether, etc.).
  • SummaryBy reconnaissance of target, the attacker discovered the server vulnerability and carried out the attack. This backdoor, a severe threat, enable attackers to penetrate computers, perform various communications and steal confidential information, such as government operations, technology research and development, and commercial operations.
  • Suggestion(1) Patch server vulnerabilities and pay attention to whether there are accounts breaches or phishing emails on the dark web to prevent from attackers' accesses. (2) Endpoint protection measures can timely detect lateral movements within Intranet.

Website hacking

Website hacking

  • Attack methodUse SQL injection, SSRF, file upload bypass, vulnerabilities of third-party package, network scanning tools (Serverscan, Xray), web backdoors (WebShell) and agents (Neo-reGeorg).
  • SummaryAttackers exploit the vulnerabilities of webpage or third-party package to upload backdoor and gain control over the website host. They then install agents and upload scanning tools for reconnaissance of intranet hosts and brute force password cracking.
  • Suggestion(1) Have vulnerability information and promptly patch and update vulnerabilities in website systems, web programs and third-party packages. (2) Regularly check management package access and website service logs. (3) Monitor the field system and network status through endpoint protection software and network management equipment to detect malicious programs in real time.

Ransomware

Ransomware

  • Attack methodUse dark web intelligence or brute force password cracking techniques through network scanning to gain access to the network or system in the field (RDP, SSH, VPN, etc.).
  • SummaryAfter entering the intranet, the attacker can move laterally, expand the scope and level of control, and finally select valuable targets for encryption and blackmail. Usually the ransom targets are ESXi hosts, NAS devices, AD, and database hosts.
  • Suggestion(1) Equipment vulnerabilities and insufficient network access verification mechanisms need to be avoided. (2) Through the terminal protection monitoring mechanism, detect suspicious programs or mobile status, detect threats early and block the source of hacking. (3) Strengthen the data backup mechanism.

Personal information leaked

Personal information leaked

  • Attack methodAttackers use network scanning (Port scan) and Web attack techniques (SQL injection, XSS, SSRF, etc.) to gain access to websites and databases in the field.
  • SummaryAttackers access and download customer order information, design fraud scenarios, and send them to victims via phone calls, emails, or text messages to defraud customers of money. From the fraud contents, the root cause of incident could be the breaches of order data. Therefore, we immediately clarified the breaches of data flow and the investigation target, and conducted evidence collection analysis.
  • Suggestion(1) It is necessary to confirm whether the web page upload verification mechanism is complete to avoid being controlled by the attacker's web shell upload. (2) Pay attention to whether the service interface is in the risks to avoid being violently cracked by attackers. (3) Strengthen the data flow encryption management and audit mechanism.

  • At the critical moment when an incident occurs, why is it so important to have TeamT5 IR support?

    The incident response aims not only to reduce the losses caused by attacks, but also learn from the incident to improve security measures. With years of IR experiences, TeamT5 can provide the following support as soon as possible: - Clarify incident status and provide emergency containment suggestions - Comprehensive endpoint scan to identify the compromise scope - Investigate the root cause of the incident and provide recommendations to defense similar attacks in the future

  • How does TeamT5 IR compare to others?

    Unlike other IR service providers, TeamT5 has more than 20 years of experience in researching in malware and Advanced Persistent Threat (APT). We specialize the adversary analysis, threat hunting, root cause analysis with practical experience in handling incidents.

  • What benefits can TeamT5's professional IR team bring to businesses and organizations?

    - Block threats and quickly clarify threats in the environment - Comprehensively investigate suspicious threats to avoid future attacks - Precise incident analysis to minimize damage - Root cause analysis and prevention suggestions to strengthen proactive defense

  • After the incident response process, how can I continue to defend against possible threats in the future?

    Since attack techniques continue to evolve, we suggest to have TeamT5 Managed Detection and Response (MDR) Service. 7*24 endpoint monitoring and periodical threat hunting, by a professional team of experienced experts, can discover threats and provide response suggestions. Once there is a suspicious incident, TeamT5's MDR team will work with the businesses and organizations to respond, conduct in-depth investigation and analysis of the root cause of the incident, and optimize security defense measures.
