“Not a mirai at all” it insists, from inside the mirai. the denial is honestly aspirational

New bot on our radar: v00lk
Android-native DDoS bot (bionic ELF, not an APK) spreading over ADB.
Surprisingly (for this malware type), the C2 is IPv6-first: it tries [2a0c:4ac1:4:1eb::a]:8443 before the v4 fallback 5.231.28[.]128:8443.

new C2:
c2.salieri[.]solutions:1995
it's a mirai/condi fork, so naming itself after the guy history remembers for not being Mozart is the most self-aware thing a botnet has done all year. no notes.

(losing track of how many families are now competing on the same proxy/ADB turf)
New, from our @deepfield ERT: found a new botnet dressing its C2 traffic as camera management.
#Drifter names its domains after Hikvision products, blending with surveillance traffic on the same VLAN as the Android TV boxes it infects. DNS…
New, from our ERT: #CECbot, an Android TV botnet and the first malware we're aware of that exploits HDMI-CEC.
It puts the TV to sleep so you don't notice the box behind it is running DDoS and residential proxy traffic. Curve25519/ChaCha20…
One custom RC4 seed led us to four botnets, five C2 channels, and a developer who shipped their Windows username and Cursor IDE logs with their malware.
Equal parts cryptography, thread-pulling, and easter eggs.
