Virus / Security Risk
The following IPs have been port scanning SMB (TCP/445) (this is windows file share port) and may well be infected by malware or viruses. Can the owners please check software they may have installed recently and run a scan for viruses.
They’ve been logged on @dizzle 's firewall trying to log into 445 (which is SMB or Windows file share port). It’s a known symptom of the WannaCry virus or similar. Some wuggers (from PTAWUG) have also noted the attacks on their anti-virus:
Thanks @dizzle for tracking down the issue. Thanks for PTAWUGgers reporting it to us also.
Scanning IPs
These will be automatically blackholed:
SMB Port Scanning (associated with various viruses like WannaCry)
I’ve implemented automatic blackholing of IPs that scan SMB ports on certain hosts. Any packet received on those ports will result in the source IP being null routed (blackholed) across CTWUG .
If you suspect you’ve been blackholed by this:
Please check if you can reach any ospf rb. If you cannot then it might be the case.
Check https://chat.ctwug.za.net/channel/security to see if your IP is listed there. Wait there for a message that it is unbanned.
Consider scanning all your PCs firewalls for WannaCry and similar.

Refer na 1ste post in thread, devices op daai IP’s van jou is baie moontlik infected

@dizzle has run a scan on one of these and it was heavily infected with multiple malwares. It was also not patched. Keep your systems up to date even if only on the wug. There are wsus servers on the wug also.
Or switch to Linux.
