Back in 2010, an unknown hackers' gang attacked PayPal when the payment service froze the account Wikileaks used. But data from the hackers' activity was enough for Pay Pal to track down the perpetrators. Consequently, PayPal has listed out 1,000 IP addresses that had an association with the hacking assault and it has handed over the list to FBI. Techmento published this on August 1, 2011.
Apparently, the IP addresses were laden with malware when the attack occurred during 2010. As a result, the agents were able to cull specific people during lately conducted raids, which resulted in 16 arrests.
Technology weblog regarding electronics for consumers Gizmodo says that the above follows as a reply to the unknown hackers' gang known as Anonymous launching a DDoS assault against the servers of PayPal during 2010. Although the IP addresses mayn't indicate anything, the FBI says they can surely evolve into a single address located within Arlington.
