Recovering from Kali Linux network manager error

I’ve been working with a virtual image of Kali recently using VMWare workstation and had a problem where the machine would work fine for a few hours and then the applications would freeze and would not allow you to open new windows or tabs(you could close existing apps)

If I restarted the virtual machine it then failed to boot. The screen would freeze on this image below and start flashing between showing the text and a black screen.

The main clue pointing the problem is the reoccurring error [Failed] Failed to start network manager:network manager 1

The first time it happened I just reinstalled the image but after the second time I thought it would be smarter to see if there was a quicker way to fix the problem. You can’t do anything from the above screen but it was possible to reinstall the network manager from recovery mode.

To do so, reboot the virtual machine and select the 2nd option from the GRUB window:

network manager 2

After that select recovery mode:

network manager 3

This will eventually ask for the root password and give you a prompt you can use to reinstall the faulty package. This will also update it if possible (which hopefully fixes the bugs causing it to crash in the first place)

sudo apt-get –reinstall install network-manager

network manager 4

 

Jack Dorsey twitter simswap

This article from the BBC today https://www.bbc.co.uk/news/uk-england-norfolk-49513692 talks about how the CEO of twitter Jack Dorsey was a victim of a sim swap attack recently where someone “tricked” a phone provider into transferring the phone number associated with Jacks account onto a different SIM which they control.

“trick” is in quotes as it could just as easily been done by paying the phone company operator to turn a blind eye and no tricks were needed. The attacker then proceeded to tweet some offensive and embarrassing things.

The interesting thing isn’t that a sim swap happened (they seem to be at almost epidemic levels currently), but that twitter doesn’t have some sort of extra controls for high level accounts which could minimise the damage caused by an account take over.

Perhaps they could look at implementing some sort of account feature which signifies that you have a “corporate” or “professional” account and automatically blocks any tweets containing offensive or rude words, or restricts tweets to only come out during predefined business hours.

if the feature also had a mandatory 24-48 hour delay between turning it off/on it would serve as a simple buffer to prevent a drunken disgruntled employee with access to a corporate account logging in at 2am and posting something offensive

It would also have made it slightly harder for whoever took over Jacks account to cause as much offence.
