Warshipping: A Free Raspberry Pi In The Mail Is Not Always A Welcome Gift

Leading edge computer security is veiled in secrecy — a world where novel attacks are sprung on those who do not yet know what they need to protect against. Once certain tactics have played out within cool kids’ circles, they are introduced to the rest of the world. An IBM …read more

Weaponized Networked Printing is Now a Thing

As such, you might not know that a battle between himself and another YouTube channel which uploads Bollywood music videos has reached such a fever pitch that his fans have resorted to guerrilla hacking to try to sway public opinion towards their side.

White-hat Botnet Infects, Then Secures IoT Devices

[Symantec] Reports Hajime seems to be a white hat worm that spreads over telnet in order to secure IoT devices instead of actually doing anything malicious.

[Brian Benchoff] wrote a great article about the Hajime Worm just as the story broke when first discovered back in October last year. At the time, it looked like the beginnings of a malicious IoT botnet out to cause some DDoS trouble. In a crazy turn of events, it now seems that the worm is actually securing devices affected by another major IoT botnet, dubbed Mirai, which has been launching DDoS attacks. More recently …read more
