Kaspersky linked Operation Daybreak to ScarCruft based on shared infrastructure and targeting, describing targeted attacks against more than two dozen high-profile victims across Asia, Europe, the Middle East, and the United States. The campaign used a previously unknown Adobe Flash Player exploit, CVE-2016-4171, delivered through a hacked website that performed browser checks before redirecting victims to attacker-controlled infrastructure in Poland. The exploit chain used Base64 and RC4 in JavaScript, randomized encrypted second-stage payloads to frustrate hash-based detection, and three Flash objects before delivering a Korean-language decoy PDF about China and North Korean nuclear issues. A second-stage DLL abused Windows DDE behavior to execute a malicious VBS and install a CAB payload containing multiple DLLs, including cldbct.dll, which connected to webconncheck.myfw[.]us:8080/8xrss.php. The use of rare payloads, invalid Tencent-themed certificates, and multiple zero-day exploit operations shows a focused actor investing in high-value targeted access.
