Hi!1.The first, You can use Hexa editor to change something of data of EEPROM.2.The second, You use a Tool to get the Password if it was set level 3 or Convert level password from level4 to 3 if your PLC was set disable upload (password level 4).3.The last, you re-write to EEPROM then you Can upload normally.
At S4x13, Scadastrangelove (@scadasl) released a offline brute force password cracking script ( ). Shortly after the script was released the functionality from that script was added into John The Ripper. Documented in The Rack is how John The Ripper is capable of cracking S7 password hashes using the Scadastrangelove technique of offline password cracking from a packet capture.
John The Ripper has been around for many years, and is one of the most common password cracking utilities out there. With an add-on plugin and a script that is easy to run, the password hashes are extracted out of packet captures, and cracked using John The Ripper.
With the rise of password complexity requirements inside of ICS environments, auditing the password complexity of PLC and like devices can be difficult and rely a lot of how much you trust the engineer. As an example there is nothing to say that the PLC configuration that you are looking at on the engineer workstation is the one that is truly pushed out to the PLC. With the ability to gather information from a packet capture and then verify the password complexity adds that much assurance to an assessment.
Password cracking is dependent on the hardware in which you are running the password cracking software on. The only testing I was able to perform was on some packet captures that were given to me from Sergey Gordeychik of Positive Technologies, and the passwords were very simple passwords that cracked within a second or two. The more complex the password the more time it takes to crack via brute force techniques, with more and more password breaches happening the word lists are getting bigger which helps the dictionary attacks get that much more powerful. I expect to see more ICS devices fall to this type of attack in the future.
The researchers found that a password can be obtained by forcing the challenge-response data extracted from TCP/IP traffic files. An attacker must be on an adjacent network to capture this traffic. The possibility exists that the code may be modified to be used against other vendor products, ICS-CERT warned. ICS-CERT has notified Siemens, it said, and has asked it to confirm the attack vector and identify mitigations.
This is not the first time that Siemens has been targeted specifically. In July 2012 the German industrial giant plugged a dynamic link library (DLL) hijacking vulnerability in SIMATIC STEP 7 and PCS 7 software, which are used to configure the same S7 programmable logic controllers that the password-cracker is targeting.
The replay attack vulnerabilities affecting the S7-1200 also are verified to affect the SIMATIC S7-200, S7-300, and S7-400 PLCs. Siemens PLCs configured with password protection are still susceptible to a replay attack.Commands between the affected PLCs and other devices are transmitted using the International Organization for Standardization Transport Service Access Point (ISO-TSAP) protocol. According to ICS-CERT analysis, the ISO-TSAP protocol is functioning to specifications; however, authentication is not performed nor are payloads encrypted or obfuscated.
Like ISO-TSAP, many protocols used in industrial control systems were intentionally designed to be open and without security features.ICS-CERT will publish additional information as it becomes available. IMPACTAn attacker with access to the PLC or the automation network could intercept the PLC password and make unauthorized changes to the PLC operation.The full impact to individual organizations is dependent on multiple factors unique to each organization.
The ICS-CERT recommends that organizations evaluate the impact of these vulnerabilities based on their environment, architecture, and operational product implementation. MITIGATIONICS-CERT continues to work with Siemens to develop specific mitigations for the reported vulnerabilities.The following mitigations can be implemented to reduce the risk of impact by the reported vulnerabilities:. ICS-CERT and Siemens recommend that asset owners/operators apply a properly configured strong password to each PLC.
Siemens recommends users immediately update SIMATIC S7-1200 and S7-1500 PLCs and corresponding versions of the TIA Portal project to the latest versions. TIA Portal V17 and related CPU firmware versions include the new PKI system protecting confidential configuration data based on individual passwords per device and TLS-protected PG/PC and HMI communication, Siemens said in its advisory.
A prominent security feature of Siemens PLCs is an access level restriction mechanism that is enforced with password protection. A password is configured within the project that is downloaded to the PLC along with a desired protection level. Those levels are:
All four levels use the same security mechanism to grant permissions to the user. The only difference between them is the extent of permissions granted with or without authentication. A password is requested upon any connection to the PLC.
Obtain the Configuration and decrypt the password hash (reading configurations from the PLC): If the PLC is in a protection level lower than 3, An attacker can retrieve the configuration from the PLC (Upload procedure) with no special permission required. Once uploaded, the attacker has the PLC configuration and can use the private key to decrypt the password hash from the uploaded configuration. Using the decrypted password hash the attacker can authenticate to the PLC and gain higher privileges.
The attacker then forwards the challenge response to the real PLC to set up an authenticated connection. This session will be a fully privileged session. At this point, the attacker may change any configuration or blocks on the PLC, or read the configuration. This access includes the ability to read the encrypted password hash from the PLC and decrypt it.
Passive Traffic Interception: An attacker with passive access to capture traffic to a given PLC on the network can intercept configuration reads/writes from the PLC. Using the private key, the attacker can decrypt the configuration and extract the password hash. With the password hash the attacker can authenticate to the controller and write a new configuration.
Users should update to current versions of the S7-1200 and S7-1500 PLC families, as well as TIA Portal v17, as advised by Siemens. TIA Portal v17 introduces a TLS management system in order to encrypt communication. Siemens also introduced a preactivated PLC configuration password requirement, that ensures all confidential PLC configuration data are protected by default as well as predefined secure PG/HMI communication, which prevents unsecured communication with other partners, and preactivated PLC access protection, that prevents any type of access to the controller unless explicitly configured.
Dear all,I have commissioned the chinese CN s7-200 PLC, & i forgot the password which i have downloaded.So how to crack the password.The password is written in system block with level 3.
Kính thưa tất cả,Tôi đã đưa việc Trung Quốc CN S7-200 PLC, và tôi quên mật khẩu mà tôi đã tải về.Vậy làm thế nào để crack mật khẩu.Các mật khẩu được ghi trong khối hệ thống với mức 3.
dear sir thanks for your nice help for version sp9 it is working fine but version 4.0.0.81 the datamanger file not support,my system is 32bit oprating os windows xp, can you send the datamanager4.0.0.81 crack the pop password
According to two researchers who spent the past few months analyzing the Chrome-powered Cr-48 beta released in December, the browser-based OS is vulnerable to many of the same serious attacks that afflict people surfing websites. As a result, users remain susceptible to exploits that can intercept email, documents, and passwords stored on centralized servers, many of which are maintained by Google 2b1af7f3a8
