Botnet Hajime "HUNTS" on Vulnerable MikroTik Routers

IS-experts have found that the IoT-botnet Hajime has initiated and now completes monstrous system filtering, looking for MikroTik's switches. 

The Bleeping Computer version reports that numerous IB masters and organizations found that the sweeps started a weekend ago, March 25, 2018. At that point various servers-traps of specialists recorded interesting action, specifically, routed to the port 8291. In the next days, the mass sweeps of the system proceeded and did not debilitate, which drew the consideration of security specialists from everywhere throughout the world. For instance, Qihoo 360 Netlab and Radware have just presented their reports on what has happened . 

As indicated by Qihoo 360 Netlab, just for three days of perceptions administrators Hajime did in excess of 860 000 outputs. 

As it turned out, aggressors are searching for helpless switches of MikroTik organization, and are attempting to abuse the issue known as Chimay Red - this is a helplessness in RouterOS rendition 6.38.4 and beneath. A bug enables an aggressor to execute self-assertive code on an issue gadget. 

It was this helplessness that was depicted in the reports distributed by Wikileaks under the name Vault 7. With its assistance a year ago, obscure jokers "renamed" a huge number of gadgets , changing the host name in blends like HACKED FTP server, HACKED-ROUTER-HELP-SOS-WAS-MFWORM - INFECTED or HACKED-ROUTER-HELP-SOS-HAD-DEFAULT-PASSWORD. 

Administrators botnet Hajime jokes, obviously, are not restricted. Through the abuse of the bug, the spread of the Hajime malvari is completed. The officially existing botnet gadgets filter irregular IP addresses, alluding to port 8291 and along these lines compute the MikroTik switches. At that point, when the objective is distinguished, the bots utilize an openly accessible exploit and deliver it to ports 80, 81, 82, 8080, 8081, 8082, 8089, 8181 and 8880. On the off chance that the activity of the bug is fruitful, the gadget turns into another "gear-tooth" in the Hajime system. 

Delegates of MikroTik know and what is going on (counting due to the messages left in official gatherings of the terrified clients). In official Twitter, the organization reminded clients that the fix for Chimay Red was discharged a year back, so it's sufficient to refresh RouterOS to the most recent form 6.41.3 (or if nothing else to 6.38.5, which incorporated a fix) , and furthermore shut the ports with a firewall.

It ought to be noticed that the mission of a huge Hajime botnet is as yet a riddle for IB specialists. Tainted gadgets are not utilized for DDoS assaults, intermediary movement or different purposes, just to contaminate oneself. Give me a chance to advise you that in 2017, specialists expected that for Hajime can stand obscure white hat'y, which along these lines are battling with Mirai and other IoT-dangers.
