IoT Malware advances

A new strain (as long as December 2016 can be called new) has been spotted on GitHub that combines both a standard telnet scanner and also MIRAI.

Next level: updating devices with malware-infected firmware?

A new article that appeared on (Hacker Claims To Push Malicious Firmware Update to 3.2 Million Home Routers ) talks about a new type of attack: devices that are being abused via their update mechanism to host a malware-infected (let’s call it malware for now) firmware.

Impossible? Not really. Of course, some of the problems that might appear are: How do you pair the device with the “right” firmware? How do you rebuild the malware-infected firmware?

But the most important question: doesn’t the device (or the manufacturer) use a rather strong security mechanism to certify that the firmware is indeed legit? If it does, maybe it’s time to update it. If not… well, trouble ahead!

Anyway, it’s not really a case of “trash the device”, rather a case of painfully (and costly) ways to identify and disinfect it.

But… does this look like the dawn of ransomware-vulnerable-devices? Yes, sure it does. Just wait for it… or better not, and be prepared.

New IoT Malware? Anime/Kami

During August 2016, we came across several devices that were infected with a new malware that we couldn’t identify – for now. It resides in a read-write partition of some CCTV devices (most partitions on these devices are read-only), in a folder called .anime under the name .kami. It seems the attack used hard-coded telnet credentials and then downloaded the now-unknown malware(or maybe created the file via “echo” commands).

CCTV Malware

We failed to identify it, since it’s truncated – the final file seems to be bigger than the partition it was created on (mounted as /mnt/mtd).

.kami: ERROR: ELF 32-bit LSB executable, Renesas SH, version 1 (SYSV), statically linkederror reading (Invalid argument)

The MD5 of it:

cdd887f2112b3d87b96154ca492368a8 .kami

For now, all we can recommend is to move devices from DMZ to proper port-forwarding and, where needed, install a router as a firewall in front of them.
