Hello, welcome to the Friday, October 19th, 2018 edition of the Sandcent Storm Center's Stormcast. My name is Johannes Ulrich, and today I'm recording from McLean, Virginia.

Cisco today released patches for 15 different vulnerabilities with a heavy focus on wireless. Most of these vulnerabilities affect the

Cisco wireless land controller and what's being fixed there are a number of

web application vulnerabilities. Nothing super critical here. There are some

directory traversal vulnerabilities and information disclosure vulnerabilities that may be used

to actually take advantage of other vulnerabilities that have been discovered in the past. Also,

there are a number of denial-of-service vulnerabilities that are being addressed, for example,

against some of the Cisco access points.

I don't see anything here that would warrant super fast patching, so just apply your standard

patch procedure to these updates.

With all the attention that cryptocurrencies have received in the last couple years,

we of course also had about a year ago,

so a big rush into new cryptocoins that were being released.

Problem here, of course, is that many of these cryptocoins really never caught on,

never really got a following, which does allow now for some 51%

attacks against these crypto coins with rather limited means. A 51% attack refers to an attack

where a single entity does actually get a hold of more than 50% of the total mining capacity for a particular coin,

and with that, this particular miner can then take control of that coin's blockchain.

An individual who goes by the name of GeoCold did launch such an attack now against Bitcoin Private.

Not to be confused with the mainstream Bitcoin, but instead Bitcoin Private is sort of a fork of the entire Bitcoin idea.

Initially, GeoCold planned to live stream the attack.

That didn't work out because multiple live streaming platforms banned him.
