Hacking group Anonymous has launched OperationUSA (#OpUSA), a coordinated online attack against nine US government sites and more than 130 financial institutions for 7 May, according to a post published in Pastebin.
The attack, according to Anonymous, would be a response to social and political injustices. "America you have committed multiple war crimes in Iraq, Afghanistan, Pakistan, and recently you have committed war crimes in your own country. …Now it is our time for our Lulz (fun)," the group said.
Organisations should be now preparing their strategies against distributed-denial-of-service attack, if they don't want to be disrupted. Besides, according to experts, call-center staff should be educated about DDoS attacks to inform costumers about possible difficulties in accessing accounts.
Network and security teams should also be monitoring online traffic and take necessary steps to block targeted IP addresses.
However, the famous hacker's organisation explained that they "cannot stop the Internet hate machine from doxes, DNS attacks, defaces, redirects, DDoS attacks, database leaks and admin takeovers."
Anonymous explained it plans to take these sites offline: "We will now wipe you off the cyber map."
Last month, Anonymous launched a cyberattack against Israel, but the operation had little impact. Nevertheless, experts affirmed that a similar attack to OpIsrael could be devastating for the US, due to the complexity of the Internet infrastructure.
With each attack, Anonymous demonstrates its power and gains experience for how to make the next operation more effective.
Despite leading US banks, such as Bank of America, HSBC or Goldman Sachs, are best prepared to fight these attacks, small ones are not and "if a massive attack will come, I'm sure we will see many of the government websites going down,” stated Ronen Kenig, an Israel-based researcher for DDoS-mitigation provider Radware.
