In this article, we will explain what direct logic plc password crack is, how it works, what are the risks, and how to prevent it.
What is Direct Logic PLC Password Crack?
Direct Logic PLC Password Crack is a term that refers to the use of software or hardware tools to retrieve or bypass the passwords of Direct Logic PLCs. Direct Logic PLCs are a series of PLCs manufactured by Automation Direct, a US-based company that provides automation products and solutions.
Some of these tools claim to support various PLCs, human-machine interfaces (HMIs), and project files from different vendors, such as Omron, Siemens, ABB Codesys, Delta Automation, Fuji Electric, Mitsubishi Electric, Schneider Electric's Pro-face, Vigor PLC, Weintek, Rockwell Automation's Allen-Bradley, Panasonic, Fatek, IDEC Corporation, and LG.
Some of these tools are legitimate and can be used for legitimate purposes, such as recovering lost passwords or resetting forgotten passwords. However, some of these tools are malicious and can be used for hacking or infecting PLCs with malware.
How Does Direct Logic PLC Password Crack Work?
Direct Logic PLC Password Crack works by exploiting a vulnerability in the firmware of Direct Logic PLCs that allows the tool to retrieve the password on command. The vulnerability, tracked as CVE-2022-2003 (CVSS score: 7.7), has been described as a case of cleartext transmission of sensitive data that could lead to information disclosure and unauthorized changes.
The vulnerability affects Direct Logic 06 PLCs with firmware versions prior to Version 2.72 released in June 2022. The vendor has issued a patch and advised users to update their firmware as soon as possible.
However, some hackers have embedded the password retrieval exploit in a malware dropper that infects the machine with the Sality malware and turns the host into a peer in Sality's peer-to-peer botnet. The Sality malware is a notorious malware family that has been around since 2003 and can perform various malicious activities, such as cryptocurrency mining, password cracking, stealing data, downloading additional malware, and spreading to other machines.
The malware dropper also drops a crypto-clipper payload that steals cryptocurrency during a transaction by substituting the original wallet address saved in the clipboard with the attacker's wallet address.
What are the Risks of Direct Logic PLC Password Crack?
The risks of direct logic plc password crack are serious and can have severe consequences for industrial systems and operators. Some of the potential risks are:
Data breach: The hackers can access sensitive data stored in the PLCs or HMIs, such as process parameters, production data, configuration settings, etc. They can also exfiltrate this data to their servers or sell it to other parties.
Data manipulation: The hackers can modify or delete data in the PLCs or HMIs, such as changing process values, altering setpoints, disabling alarms, etc. This can cause disruptions, malfunctions, or damage to the industrial processes and machines.
Data destruction: The hackers can erase or overwrite data in the PLCs or HMIs, such as wiping out firmware, deleting programs, corrupting files, etc. This can render the PLCs or HMIs unusable or inaccessible.
Malware infection: The hackers can infect the PLCs or HMIs with malware that can perform various malicious activities, such as cryptocurrency mining, password cracking, stealing data, downloading additional malware, spreading to other machines, etc. This can compromise the performance, security, and integrity of the industrial systems and networks.
Cyberattack: The hackers can use the compromised PLCs or HMIs as a launchpad for further cyberattacks against other targets in the industrial network or beyond. They can also use them as a ransomware vector to extort money from the victims.
How to Prevent Direct Logic PLC Password Crack?
The best way to prevent direct logic plc password crack is to update the firmware of Direct Logic PLCs to Version 2.72 or later as soon as possible. This will fix the vulnerability that allows the password retrieval exploit to work.
However, updating the firmware alone is not enough. Users should also follow these best practices to enhance the security of their PLCs and HMIs:
Use strong passwords: Users should use strong passwords that are hard to guess or crack. They should avoid using default passwords or common passwords that can be easily found online. They should also change their passwords regularly and not reuse them across different devices or accounts.
Encrypt passwords: Users should encrypt their passwords using secure encryption algorithms and protocols. They should also avoid storing or transmitting their passwords in cleartext or insecure channels.
Protect passwords: Users should protect their passwords from unauthorized access or disclosure. They should not share their passwords with anyone or write them down on paper or digital media. They should also use password managers or vaults to store and manage their passwords securely.
Monitor passwords: Users should monitor their passwords for any signs of compromise or misuse. They should check their login history and activity logs regularly and report any suspicious or anomalous events. They should also enable alerts or notifications for any password changes or resets.
Audit passwords: Users should audit their passwords periodically and ensure they comply with security policies and standards. They should also review their password inventory and remove any unused or obsolete passwords.
Direct Logic PLC Password Crack is a serious threat that can compromise the security and safety of industrial systems and operators. Users should update their firmware to fix the vulnerability that enables the exploit and follow best practices to protect their passwords from hackers.
How to Crack Direct Logic PLC Passwords?
There are different methods and tools to crack direct logic plc passwords, depending on the type and model of the PLC. Some of these methods and tools are:
Brute force attack: This method involves trying all possible combinations of characters until the correct password is found. This can be done manually or with the help of software tools that automate the process. However, this method is very time-consuming and inefficient, especially if the password is long and complex.
Dictionary attack: This method involves trying a list of common or likely passwords that are stored in a file or database. This can be done manually or with the help of software tools that automate the process. However, this method is also ineffective if the password is not in the list or if the list is too large.
Phishing attack: This method involves tricking the user into revealing their password by sending them a fake email or website that looks like a legitimate one. The user is then asked to enter their password or click on a link that leads to a malicious site that captures their password. However, this method requires social engineering skills and relies on the user's gullibility.
Spyware attack: This method involves installing a malicious software on the user's computer or device that monitors their keystrokes or clipboard and sends their password to the attacker. However, this method requires physical access to the user's computer or device or exploiting a vulnerability to remotely install the spyware.
Firmware exploit: This method involves exploiting a vulnerability in the firmware of the PLC that allows the attacker to retrieve or bypass the password. This can be done with the help of software tools that embed the exploit in a malware dropper or a legitimate file. However, this method requires finding and exploiting a specific vulnerability that affects the PLC.
