Yesterday鈥檚 massive cyber attack, which took down internet giants such as Twitter, Netflix, Spotify and the like, has left people (us included!) frantically searching for answers after hackers deployed a聽DDoS (distributed denial of service) on internet services firm Dyn in the early hours of Friday morning. Wreaking havoc on our most beloved go-to sites, the attack was a beast unlike any we鈥檝e seen. Almost as soon as engineers managed to stop it, a second attack took place, crippling our internet powers once more.聽Access to Dyn鈥檚 long list of clients was (finally, FINALLY!) restored, but many questions still remain: namely, what the hell just happened, and, perhaps more importantly, whodunnit? Here鈥檚 what we know so far.

HAMBURG, GERMANY - DECEMBER 28: Participant hold their laptops in front of an illuminated wall at the annual Chaos Computer Club (CCC) computer hackers' congress, called 29C3, on December 28, 2012 in Hamburg, Germany. The 29th Chaos Communication Congress (29C3) attracts hundreds of participants worldwide annually to engage in workshops and lectures discussing the role of technology in society and its future.

According to Fortune,聽the attack was carried out by hijacking something called the聽Internet of Things (which is, essentially, a network of聽interconnected devices that are聽able to exchange data with one another, such as cameras and DVRs) to carry out聽the DDoS. Hackers used聽the Internet of Things to flood the Dyn system with 鈥渇ake鈥澛爏ignals, thereby rendering it unable to process its normal signals and be effective.

Echoing this fact,聽FlashPoint聽confirmed that hackers used聽Mirai malware (a virtual virus robot) to target聽the Internet of Things, which聽allowed them聽to 鈥渆nslave vast numbers of these devices into a botnet, which [was]聽then used to conduct DDoS attacks.鈥澛燯h, yikes?

It鈥檚 interesting (and frightening) to note that the聽Mirai malbot software used was actually made聽public聽earlier this month.聽That聽makes hunting down the perpetrators all the more difficult,聽because, well, the entire world had access to it. We have since聽discovered that 鈥渕ost of the components involved were made by one company, China鈥檚 XiongMai Technologies.鈥 Could that serve as a clue? That remains to be seen.

The reason for聽the attack is also a big question mark, but聽several theories have since surfaced. Some believe the hackers had blackmail plans and simply wanted money. Others have said the attacks were a form of protest orchestrated by supporters of WikiLeaks founder聽Julian Assange (who is now in exile in Ecuador) because his access to the Web was recently cut off.

Meanwhile, others still are pointing the finger聽closer to home.聽IBTimes UK spoke with聽Adam Horsewood, Senior Security Consultant at MWR Infosecurity, who said: 鈥淭he attack on Dyn could well be a form of advertising. Dyn provide a DDoS defense service, protecting clients from the very same sort of attacks that they are now suffering.鈥

While any of聽these theories could prove feasible and are聽certainly food for thought, we have no idea which one is actually correct. It IS safe to say that聽it might be time to be a litttttttllle bit more careful regarding our internet activity, and to make backup plans for necessary services where we can. Internet vacation, anyone?
