The LockBit Ransomware Gang's Attack on AICSA
The LockBit ransomware gang has attacked AICSA. AICSA is a Guatemalan company specializing in designing, constructing, and developing commercial, corporate, residential, infrastructure, and energy projects. LockBit posted AICSA to its data leak site on October 3rd but provided no further details.
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's Modus Operandi
LockBit employs publicly available file sharing services and a custom tool dubbed Stealbit for data exfiltration. 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 and introduced LockBit 3.0 in June of 2022. The latest version incorporates advanced anti-analysis features and is 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.
Encryption Techniques and Targets
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 tends to target larger enterprises across any industry vertical with the ability to pay high ransom demands, but also tends to favor Healthcare targets.
Affiliate Program and Extortion Techniques
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.
Recent Ransomware Attacks
The Recent Ransomware Attacks (RRA) site acts as a watchtower, providing you with near real-time ransomware tracking of attacks, groups and their victims. Given threat actors’ overarching, lucrative success so far, ransomware attacks have become the most ubiquitous, and financially and informationally impactful cyber threat to businesses and organizations today.
The site’s data is generated based on hosting choices of real-world threat actors, and a handful of other trackers. While sanitization efforts have been taken, we cannot guarantee 100% accuracy of the data. Attack updates will be made as source data is reported by reputable sources. By viewing, accessing, or using RRA you acknowledge you are doing so at your own risk.
