Zero-day exploit




A zero-day exploit is a technique that exploits a previously unknown or unpatched vulnerability in the PLC device or software. A zero-day exploit can allow an attacker to gain full access to the PLC device without requiring the password. A zero-day exploit can also allow an attacker to retrieve the password in clear text from the PLC memory or configuration file.


One example of a zero-day exploit that affects Simatic S7 200 PLC is CVE-2020-15782, which was disclosed by the Cybersecurity and Infrastructure Security Agency (CISA) in November 2020. CVE-2020-15782 is a vulnerability that allows an attacker to read and write arbitrary data to the PLC device over the network using a specially crafted packet. CVE-2020-15782 affects Simatic S7 200 SMART PLCs with firmware versions prior to V2.5. CVE-2020-15782 can be exploited by using a tool called S7Exploit, which is available on GitHub. S7Exploit can read and write data blocks, system data, and passwords from the PLC device.


Trojanized software




A trojanized software is a software that has been modified or infected by malware that performs malicious actions in the background. A trojanized software can be used to crack the PLC password by tricking the user into installing or running the software on their computer or PLC device. A trojanized software can also be used to deliver malware or ransomware to the PLC device or the connected network.


One example of a trojanized software that affects Simatic S7 200 PLC is Sality, which is a well-known malware that has been around for two decades. Sality is often used by cybercriminals for financial gain. Sality can infect executable files, block antivirus software, steal cryptocurrency, perform distributed password cracking, and join a peer-to-peer botnet. Sality can infect Simatic S7 200 PLC by replacing the original STEP 7-Micro/WIN software with a malicious version that contains a crypto-clipper payload. A crypto-clipper payload is a type of malware that steals cryptocurrency during a transaction by substituting the original wallet address saved in the clipboard with the attacker's wallet address. This way, the victim unknowingly sends the cryptocurrency to the wrong destination. Brute-force attack




A brute-force attack is a technique that tries to guess the PLC password by using a large number of possible combinations. A brute-force attack can be performed by using a tool that generates and tests different passwords based on a dictionary, a list, or a pattern. A brute-force attack can also be performed by using a tool that captures and analyzes the PLC communication packets to extract the password.


One example of a brute-force attack that affects Simatic S7 200 PLC is PLC-Blaster, which is a tool that was developed by researchers from Ruhr University Bochum in Germany. PLC-Blaster can crack the PLC password by using a dictionary attack or a hybrid attack. A dictionary attack uses a predefined list of common or weak passwords, such as "1234", "admin", or "password". A hybrid attack uses a combination of dictionary words and additional characters, such as "admin123", "password!", or "1234abcd". PLC-Blaster can also crack the PLC password by using a packet sniffer attack, which captures and analyzes the PLC communication packets to extract the password. PLC-Blaster can crack the PLC password in less than 10 minutes, depending on the password complexity and length.
