This rule detects GwisinLocker ransomware activity on Linux systems. It identifies specific byte patterns associated with the ransomware's key initialization, file encryption routines, file discovery mechanisms, process termination, and ESXi shutdown capabilities. The rule has two main versions (v1 and v2) of these functionalities, and a match occurs if all parts of either version are found.
Yara rule that detects GwisinLocker ransomware.
This YARA rule detects the RedAlert ransomware by identifying specific byte patterns within the executable. The patterns correspond to functions involved in setting up the environment, finding files to encrypt, encrypting files, and making configuration changes, which are characteristic behaviors of the RedAlert ransomware.
Yara rule that detects RedAlert ransomware.
This YARA rule detects the KillDisk ransomware by identifying specific byte patterns associated with its file encryption routines, file searching mechanisms, and its capability to subvert GRUB (Grand Unified Bootloader). The rule looks for a combination of these patterns within a file, indicating the presence of KillDisk ransomware, which is known for its data wiping and encryption capabilities, often rendering systems unbootable.
This YARA rule detects the Linux-based LuckyJoe ransomware by identifying specific byte patterns within its main call functions and encryption routines. The rule looks for distinct sequences of assembly instructions related to the ransomware's core operations, including file encryption and internal message handling. The condition requires all parts of these identified patterns to be present, along with the ELF magic number, to ensure high fidelity detection of the LuckyJoe executable.
This YARA rule detects the Kraken ransomware by identifying specific byte patterns associated with its functionality. The rule looks for sequences related to enumerating volumes, enumerating network shares, finding files, and encrypting files. The presence of these combined patterns indicates the likely presence of Kraken ransomware.
