Cadelspy

Cadelspy is a type of malware that has recently been infecting computers, compromising their security and stealing sensitive data. The malware infiltrates the system as a dropper, downloading two installer components based on whether the victim's system is 32-bit or 64-bit. Once inside, it executes the appropriate installer, launching its malicious payload and enabling it to run whenever any Windows program is executed. Cadelspy's main payload includes backdoor functionality, which allows it to perform various threatening activities. Our telemetry data indicates that more than a dozen entities have experienced infections from both Cadelspy and another malware, Remexi. These infections occurred within a close time frame, suggesting a coordinated attack. Interestingly, four of these entities were compromised with both threats at some point. One notable case involved a system running a SIM card editing application, which was infected with both Cadelspy and Remexi. Cadelspy operates by compressing all stolen data into a .cab file and uploading it to the attacker’s Command & Control (C&C) servers. This method of operation poses significant risks to the confidentiality and integrity of the infected systems' data. In comparison, Chafer’s threat Remexi contains fewer features than Cadelle’s Cadelspy, but it still poses a substantial threat to cybersecurity. Therefore, it is crucial for organizations to take necessary precautions to safeguard their systems against these types of malware.
