Cybersecurity has become a crucial priority for modern
businesses facing increasingly sophisticated and diverse threats. Lateral
movements, where an attacker moves through a network after an initial breach,
represent one of the most dangerous and insidious techniques. They allow
cybercriminals to expand their access and compromise critical resources, often
before detections and responses can be implemented. Understanding these lateral
movements and implementing effective solutions to counter them is essential for
protecting digital assets and ensuring operational continuity.
I – DANGERS OF LATERAL MOVEMENTS WITHIN A NETWORK
Lateral movements within a network can lead to serious and
widespread damage. Once an attacker has compromised an access point, they can
progressively extend their control and reach critical targets. Here is a
detailed analysis of the main types of resulting damage:
1.
Compromise
of Sensitive Data:
o Impact:
Unauthorized access to network segments containing sensitive information
(customer data, financial information, intellectual property records) can lead
to data breaches, leaks of confidential information, and significant financial
losses. These incidents can also result in hefty fines for non-compliance with
regulations.
o Consequences:
Financial damage may include notification costs, regulatory fines, and legal
fees. In addition, loss of customer trust can have long-term repercussions on
the company’s reputation.
2.
Industrial
Espionage:
o Impact:
Unauthorized access to internal resources allows the theft of trade secrets,
product plans, or proprietary technologies. Industrial espionage can give rival
companies a competitive advantage and damage the targeted company’s reputation.
o Consequences:
Market share losses and reputational damage can be significant, affecting the
company’s competitive position in the market.
3.
System
Sabotage:
o Impact:
Attackers can modify, destroy, or alter critical systems, leading to production
shutdowns or the paralysis of IT services. Such sabotage can cause prolonged
operational disruptions, with significant economic and operational impacts.
o Consequences:
Service interruptions can result in direct financial losses, contractual
penalties, and disruptions in daily operations.
4.
Spread of
Malware:
o Impact: Lateral
movements facilitate the rapid spread of malware (ransomware, trojans) across
the network. Ransomware, for example, can encrypt files on multiple machines,
causing loss of data access and forcing the company to pay a ransom.
o Consequences:
The impact may include the loss of critical data, recovery costs, and
significant operational disruption.
5.
Takeover
of Infrastructure:
o Impact:
Attackers can establish backdoors and maintain persistent access to the
network, allowing servers to be hijacked for malicious activities
(cryptocurrency mining, DDoS attacks) or continuous exfiltration of
information.
o Consequences:
This can lead to abuse of computing resources, ongoing security breaches, and
impacts on system performance.
6.
Loss of
Trust and Reputational Impact:
o Impact: Data
leaks or disruptions caused by lateral attacks can severely affect a company’s
reputation. Loss of trust from customers, partners, and investors can lead to
decreased sales and deterioration of the company’s value.
o Consequences:
Reputational repercussions may result in loss of customers, contract breaches,
and a decrease in the company’s value.
7.
High
Recovery Costs:
o Impact: Recovery
after lateral contamination requires significant investments to analyze and
repair compromised systems, including data restoration, the implementation of
new security measures, and legal fees related to litigation or fines.
o Consequences:
Recovery costs may include consultant fees, additional security technology
expenditures, and costs related to remediation of affected systems.
In summary, lateral movements can turn a simple intrusion
into a devastating attack, affecting the security, finances, and operational
continuity of the business. That is why it is imperative to implement robust
solutions to prevent such threats.
II – METHODS USED BY HACKERS TO PERFORM LATERAL MOVEMENTS
Hackers use a variety of techniques to carry out lateral
movements within a network after an initial breach. Here are the most common
methods:
1.
Credential
Theft:
o Method:
Attackers steal login credentials (passwords, tokens) from other users after
accessing a machine. They then use these credentials to connect to other
systems.
o Techniques:
Phishing, keylogging, data extraction from compromised systems.
2.
Exploitation
of Vulnerabilities:
o Method: Hackers
identify unpatched vulnerabilities in other parts of the network, allowing them
to take control of additional machines.
o Techniques:
Exploitation of unpatched security flaws, leveraging software weaknesses.
3.
Use of
Administrative Scripts:
o Method: Hackers
exploit native tools like PowerShell or PsExec to execute remote commands on
other systems, making their activities less suspicious.
o Techniques:
Script execution to deploy payloads, remote manipulation of system settings.
4.
Internal
Reconnaissance:
o Method:
Attackers map the network to identify interesting targets (file servers,
databases, etc.), using tools like ARP scanning or Netstat.
o Techniques:
Network scans to identify accessible resources, network configuration analysis.
5.
Data
Exfiltration:
o Method: After
compromising multiple machines, attackers gather critical or sensitive data and
exfiltrate it out of the network.
o Techniques:
Use of unsecured communication channels to transfer data, exploitation of
network storage and transfer capabilities.
III – HOW ARCHANGEL 2.0 PREVENTS SUCH MOVEMENTS
PT SYDECO researchers designed ARCHANGEL 2.0 to prevent
lateral movements by combining micro-segmentation and a secure VPN. Here’s how
this innovative solution protects against the attack techniques described
above:
- Micro-segmentation:
- Principle:
ARCHANGEL 2.0 isolates each resource or application within the network,
limiting communication between segments to authorized paths. This prevents
an attacker from accessing other parts of the network, even if they
manage to compromise one point.
- Advantage:
Segments are compartmentalized so that unauthorized access to one segment
does not allow access to other segments or critical resources.
- Secure
VPN:
- Principle:
The VPN server, installed in the system, creates a secure perimeter where
all connections must pass through. It controls access and ensures that
only authenticated users can access the network.
- Advantages:
- Complete Access Control: Eliminates the risk of
unauthorized external access by requiring strict authentication.
- Protection Against External Threats: Prevents direct access to
the company’s internet without going through the VPN.
- Enhanced Network Segregation: Users only have access to
necessary resources, limiting their ability to move laterally.
IV – PRACTICAL APPLICATION OF THE ARCHANGEL 2.0 SYSTEM
AGAINST ATTACK METHODS
ARCHANGEL 2.0 is designed to effectively counter the most
common attack techniques:
1.
Credential
Theft:
o Secure VPN:
Network access is conditioned by strong authentication via VPN, with
multi-factor authentication (MFA) to reduce the risk of credential theft.
2.
Exploitation
of Vulnerabilities:
o Micro-segmentation:
By compartmentalizing resources, ARCHANGEL 2.0 reduces the chances of
exploiting unpatched vulnerabilities in other network segments.
3.
Use of
Administrative Scripts:
o Micro-segmentation and Secure VPN: Limits access to administration tools and scripts to
specific and controlled segments, while requiring VPN authentication for any
remote activity.
4.
Internal
Reconnaissance:
o Micro-segmentation:
Prevents unauthorized internal reconnaissance by limiting the visibility of
segments to authorized users only.
5.
Data
Exfiltration:
o Secure VPN:
Ensures that all data exfiltration passes through secure and monitored
channels, reducing the risk of undetected exfiltration.
