Hi All I'm told that the local WISP operator community is dealing with a new worm[1] that exploits Ubiquiti AirOS devices running older firmwares. This could potentially be a lot of devices. http://community.ubnt.com/t5/airMAX-General-Discussion/Virus-attack-URGENT-U... has ISPs from Spain, Brasil, and the US reporting infections in thelast 24 hours. Versions prior to these are vulnerable: 5.5.11 XM/TI. 5.5.10u2 XW 5.6.2 XW/XM/TI There looks to be some more information here which might or might not be related. https://hackerone.com/reports/73491 If you know anyone who makes use of UBNT AirOS products, now might be a time to give them a nudge. [1] quote from the forums "It's a self-distributing virus, so, once it can "see" neighbour antenas within the same subnet, it attacks the others."
