The hackers who temporarily knocked out a part of the internet in the US and Europe last month attempted four Mirai botnet Distributed Denial of Service (DDoS) attacks to cripple the campaign websites of Donald Trump and Hillary Clinton.

According to findings from cyber security firm Flashpoint, the massive cyberweapon Mirai malware misfired this week when hackers tried to take down the campaign websites of US presidential candidates Hillary Clinton and Donald Trump

The company observed four 30-second HTTP Layer 7 attacks against Trump's website on Sunday. On Monday, a separate set of attacks against both Trump and Clinton's campaign sites were discovered.

However, the attacks failed, and neither site observed, reported or experienced any outages because the Mirai botnet is getting weaker.

"Flashpoint assesses with moderate confidence that the Mirai botnet has been fractured into smaller, competing botnets due to the release of its source code, which has led to the proliferation of actors exploiting the botnet's devices," Flashpoint said.

Researchers and Flashpoint cyber intelligence analysts say they do not think that the attacks were carried out by nation-state actors, as each attack seemed to be distinct and powered by different groups.

They stated that attacks were likely to be the work of "unsophisticated actors" as they were all perpetrated using the Mirai IoT botnet.

The Mirai botnet is a bunch of infected Internet-connected devices -- mostly digital cameras -- that operates like a mega cannon. It floods computer servers with an immense amount of data, taking out websites and potentially knocking companies off the internet.

This new weapon made its big splash on October 21 when it stopped people from accessing Netflix, Spotify, and Twitter for hours.

Earlier in October, hackers released the source code for the Mirai malware, which experts warned would set off multiple cyber attacks from new botnets powered by compromised web-connected devices.
