Mirai Variant MooBot Targeting D
Unit 42 observed the MooBot Mirai variant exploiting four D-Link vulnerabilities to compromise unpatched routers for use in DDoS attacks.
Unit 42 captured attacks exploiting four D-Link remote code execution vulnerabilities: CVE-2015-2051, CVE-2018-6530, CVE-2022-26258, and CVE-2022-28958, with three rated critical at CVSS 9.8. The exploits download the MooBot malware, a Mirai botnet variant, from infrastructure at 159.203.15.179 via wget. Compromised devices fall under full attacker control and can be used for distributed denial-of-service attacks. D-Link has published bulletins for all four flaws, but unpatched devices remain exposed.

NOKKI Almost Ties the Knot with DOGCALL: Reaper Group Uses New Malware to Deploy RAT
Unit 42 links NOKKI malware to North Korea's Reaper group, uncovering the Final1stspy dropper that deploys the DOGCALL RAT in politically motivated attacks.
Unit 42 analyzed the NOKKI malware family used in politically themed attacks against Russian and Cambodian speakers since July 2018. The researchers linked NOKKI to the Reaper group, publicly attributed to North Korea, whose custom DOGCALL RAT uses third-party hosting services to upload data and receive commands. A previously unreported family, Final1stspy, was found deploying DOGCALL, sharing a unique base64-to-hex deobfuscation routine with NOKKI droppers. Attacks used malicious Microsoft Word macros that download and execute payloads while opening decoy documents.
