Post-exploitation and pivoting in Cybersecurity - Step-by-Step Execution

Concept Flow - Post-exploitation and pivoting

Gain initial access

↓

Establish control on target

↓

Gather information inside network

↓

Identify other systems to reach

↓

Use pivoting to move laterally

↓

Access new targets through pivot

↓

Repeat or escalate privileges

↓

Maintain persistence or exfiltrate data

This flow shows how after getting into one system, an attacker controls it, learns about the network, and moves sideways to other systems using pivoting.

Execution Sample

Cybersecurity

1. Access machine A
2. Run commands to find machines B and C
3. Use machine A as a pivot to connect to B
4. Access B and repeat

This sequence shows how an attacker uses one compromised machine to reach others inside a network.

Analysis Table

Step	Action	Target System	Result	Notes
1	Gain initial access	Machine A	Access granted	Entry point into network
2	Gather info	Machine A	Found Machines B and C	Network mapping
3	Setup pivot	Machine A	Pivot established	Allows connection to B via A
4	Connect via pivot	Machine B	Access granted	Lateral movement successful
5	Repeat process	Machine B	Further targets found	Potential for escalation
6	Exit	-	-	No more targets or stopped

💡 No more targets found or attacker stops after step 6

State Tracker

Variable	Start	After Step 2	After Step 4	Final

Pivot Established	No	No	Yes	Yes
Targets Found	Unknown	Machines B and C	Machines B and C	Machines B and C

Key Insights - 2 Insights

Why does the attacker need to use pivoting instead of directly accessing other machines?

Because other machines may not be reachable directly from outside; pivoting uses the compromised machine as a bridge, as shown in step 3 and 4 of the execution_table.

What does 'gathering information' involve after initial access?

It means finding other machines and network details from the compromised system, as seen in step 2 where machines B and C are discovered.

Visual Quiz - 3 Questions

Look at the execution_table, at which step is the pivot established?

A Step 2

B Step 3

C Step 4

D Step 5

💡 Hint

Check the 'Action' and 'Result' columns in the execution_table for when pivoting is set up.

According to variable_tracker, which systems are accessed after step 4?

A Machines A and B

B Machines B and C

C Only Machine A

D No machines accessed

💡 Hint

Look at the 'Accessed Systems' row after 'After Step 4' column.

If the attacker cannot find any other machines after step 2, what happens to the pivoting process?

A Attacker gains direct access to all machines

B Pivoting proceeds to other machines anyway

C Pivoting is not possible and stops

D Pivoting happens on the same machine

💡 Hint

Refer to the exit_note and the importance of finding targets in step 2.

Concept Snapshot

Post-exploitation means controlling a compromised system to explore and move inside a network.
Pivoting uses one compromised machine as a bridge to access others.
Steps: Access → Control → Gather info → Pivot → Access new targets.
Pivoting is needed when direct access to other machines is blocked.
It helps attackers move laterally and escalate their reach.

Full Transcript

Post-exploitation and pivoting is a process attackers use after breaking into one computer. First, they gain control of that machine. Then, they look around the network to find other computers. Because they often cannot reach these other computers directly, they use the first machine as a stepping stone. This is called pivoting. By connecting through the first machine, they can access others inside the network. They repeat this process to move deeper or get higher access. The execution table shows each step from initial access to pivoting and moving laterally. The variable tracker shows how accessed systems and pivot status change over time. Key moments clarify why pivoting is necessary and what gathering information means. The quiz tests understanding of when pivoting happens and what systems are accessed. Overall, this helps learners see how attackers move inside networks after initial entry.
