The LockBit Ransomware Gang's Attack on Ragasa

The LockBit ransomware gang has attacked Ragasa. Ragasa, formally known as "Rancho Agícola Ganadero, S.A. de C.V.," is a prominent Mexican agroindustrial company with a rich history dating back to its establishment in 1970. Headquartered in Mexico, Ragasa has become a leading player in the country's agroindustrial sector. The company is renowned for its diverse range of activities, which encompass crop cultivation, livestock farming, and the processing of agricultural products. In particular, Ragasa is known for its involvement in the production of essential crops like soybeans and corn, contributing significantly to Mexico's agricultural landscape.

LockBit posted Ragasa to its data leak site on September 6th but provided no further information. LockBit is a RaaS (Ransomware-as-a-Service) that has been active since 2019 and is enabled with security tool evasion capabilities and an extremely fast encryption speed. LockBit is noted for using a triple extortion model where the victim may also be asked to purchase their sensitive information in addition to paying the ransom demand for decrypting systems. LockBit employs publicly available file sharing services and a custom tool dubbed Stealbit for data exfiltration.

LockBit's Activity and Evolution

LockBit was by far the most active attack group in 2022 and continued to be one of the top attack groups in Q1 of 2023, despite being bested in sheer volume by the Cl0p ransomware gang who surged in Q1.‍ LockBit demanded ransoms in excess of $50 million in 2022. The group continues to improve their RaaS platform following the release of LockBit 3.0 in June of 2022, adding what may be the first iteration of macOS ransomware in April of 2023. The latest versions incorporate advanced anti-analysis features and are a threat to both Windows and Linux systems.

LockBit 3.0 is modular and configured with multiple execution options that direct the behavior of the ransomware on the affected systems. LockBit employs a custom Salsa20 algorithm to encrypt files. LockBit takes advantage of remote desktop protocol (RDP) exploitation for most infections, and spreads on the network by way of Group Policy Objects and PsExec using the Server Message Block (SMB) protocol. LockBit appears to also still be supporting the older LockBit 2.o variant from 2021, where the encryptor used is LockBit 2.0 but the victim is named on the LockBit 3.0 leak site.

Targeting and Extortion Techniques

LockBit tends to target larger enterprises across any industry vertical with the ability to pay high ransom demands, but also tends to favor Healthcare targets. LockBit a very well-run affiliate program and a great reputation amongst the affiliate (attacker) community for the maturity of the platform as well as for offering high payouts of as much as 75% of the attack proceeds. LockBit is known to employ multiple extortion techniques including data exfiltration to compel payment.
