Direct Logic Plc Password [PATCHED] Crack

Tools advertised as being capable of cracking passwords for HMIs, PLCs and other industrial products have been found to exploit a zero-day vulnerability, and threat actors are using these tools to deliver malware.
Dragos has investigated a tool designed for DirectLogic PLCs from AutomationDirect, but the same threat actor also offers password cracking software for several other products from Omron, Siemens, ABB, Delta Automation, Fuji Electric, Mitsubishi Electric, Pro-face (Schneider Electric), Vigor, Allen-Bradley (Rockwell Automation), Panasonic, LG, Fatek, and IDEC.
Multiple accounts across a variety of social media websites are advertising Programmable Logic Controller (PLC), Human-Machine Interface (HMI), and project file password cracking software. Buyers can retrieve forgotten passwords by running an executable provided by the seller that targets a specific industrial system.
Previous research targeting DirectLogic PLCs has resulted in successful cracking techniques. However, Dragos found that this exploit does not crack a scrambled version of the password as historically seen in popular exploitation frameworks. Instead, a specific byte sequence is sent by the malware dropper to a COM port.
Sality is a peer-to-peer botnet for distributed computing tasks such as password cracking and cryptocurrency mining. A Sality infection could risk remote access to an EWS by an unknown adversary. Dragos assesses with moderate confidence the adversary, while having the capability to disrupt industrial processes, has financial motivation and may not directly impact Operational Technology (OT) processes.
Security researchers at industrial cybersecurity company Dragos analyzed one incident impacting DirectLogic PLCs from Automation Direct and discovered that the \"cracking\" software was exploiting a known vulnerability in the device to extract the password.
But behind the scenes the tool also dropped Sality, a piece of malware that creates a peer-to-peer botnet for various tasks that require the power of distributed computing to complete faster (e.g. password cracking, cryptocurrency mining).
Industrial engineers and operators are the target of a new campaign that leverages password cracking software to seize control of Programmable Logic Controllers (PLCs) and co-opt the machines to a botnet.
The infections culminate in the deployment of the Sality malware for carrying out tasks such as cryptocurrency mining and password cracking in a distributed fashion, while also taking steps to remain undetected by terminating security software running in the compromised workstations.
\"In general, it appears there is an ecosystem for this type of software,\" Hanson noted, attributing the attacks to a likely financially motivated adversary. \"Several websites and multiple social media accounts exist all touting their password 'crackers.'\"
Dragos is reporting that one such group offering password cracking for 15 vendors worth of PLCs and HMIs is using the password recovery software to install the Sality botnet. Sality is used for distributed criminal tasks, including cryptomining.
A threat actor is targeting industrial engineers and operators with trojanized password-cracking software for programmable logic controllers (PLCs) and human-machine interfaces (HMIs), exploiting their pressing needs to turn industrial workstations into dangerous bots.
According to Dragos researchers, the adversary seems not to be interested in disrupting industrial processes but making money. The password-cracking software also carries a dropper that infects the machine with Sality malware, which:
Several websites and multiple social media accounts are touting password-cracking software for PLCs, HMIs and project files, Dragos researchers have found. These appear to be tailor-made to work on PLCs and HMIs by AutomationDirect, Omron, Siemens, ABB, Delta Automation, Fuji Electric, Mitsubishi Electric, Pro-Face, Vigor Electric, Weintek, Allen-Bradley, Panasonic, Fatek, IDEC Corp., and LG.
Threat actors behind the campaign used multiple accounts across several social media platforms to advertise password-cracking software for Programmable Logic Controller (PLC), Human-Machine Interface (HMI), and project files.
Dragos experts investigated an infection of DirectLogic PLCs from Automation Direct, they performed reverse engineering of the password cracking tool and discovered it did not crack the password at all, rather, it exploited a vulnerability in the firmware to retrieve the password on command. The password cracking software also acts as a dropper for the Sality P2P bot.
Once running on the PC, Sality joins a peer-to-peer network, and provides remote access to the system. Its intentions appear to be more financial than destructive, with the software nasty aimed at distributed computing tasks, such as cracking passwords and mining cryptocurrency. In addition, it uses a range of techniques to evade detection.
Engineers may have legitimate reasons for downloading such password-cracking software. For example, they may be on a tight project deadline and need to find a forgotten password, or recover access to a device after its operator suddenly quits without documenting these credentials. However, using a sketchy-looking recovery tool from the internet would introduce \"significant and unnecessary risk into the OT environment,\" Dragos and anyone with common sense concluded. 153554b96e
