Are you having trouble to access the Malwr.com website? Then it could be that they are working on their servers.
It is also a possibility that they are a victim of a cyberattack.
The Malwr.com website is under continous attacks by angry cybercriminals.
Why you might ask? The reason is pretty clear, the website is creating a massive database of Malware. These malware samples are used by the anti-virus community to protect their clients against cybercriminals that are after personal information and other values which can be found/used on the victim computers.
We are target of a DNS amplification attack apparently gunning other anti-malware services as well. The DDOS should be mitigated for now.
