Got a call from these guys on my landline, but I kept pretending the line was faulty by hanging up a few times until they finally rang my PBX number.
The numbers they called from are:
01143 602 581
01809 362 120
01776 141 719
01305 686 897
Asked to connect to my computer, usual fake crap with Event Viewer and NetStat via CMD.
When, after 45 mins of wasting their time, I knew they were scammers, the guy ADMITTED he was a scammer and said he couldn't get any further work.
In the end, he said he did nasty things to my (non-existent) daughter and mother, and hung up after I called him a nasty word in Indian.
I then got a call back from his "supervisor" complaining I was rude to him! I informed him of the nasty things he said to me first, then told him to get "f'd" and they hung up.
I've blocked the numbers on my system since (they get sent to an automated recording basically telling them with a computerised voice to get lost in a rather rude way).
