Deep Panda
This hacking group appears to be sponsored by the Chinese government. It has been tied to several successful attacks in the last year. The security firm Crowd Strike named them Deep Panda.
The hacker’s latest work may have been the massive Anthem data breach, which exposed the personal information of more than 80 million insurance policyholders. The cyberattack puts Anthem customers at risk for identity theft throughout their lives, and exposed many to subsequent phishing attacks from fraudsters around the world. Deep Panda has been tied to cyberattacks on U.S. foreign policy think tanks and individuals who are experts on the Middle East and Australian media outlets. A 2014 investigation by Crowd Strike also blamed the group for sending malware to organizations across the U.S. defense, healthcare and technology sectors.
Deep Panda is considered one of the most sophisticated hacking groups operating today. Just last month, the Federal Bureau of Investigation warned the cybersecurity community that the group represents a threat. “This group uses a wide variety of tools including generic hacking utilities in order to gain access, establish persistent network access, and move laterally though the victim network,” an FBI official stated in a memo.

Flying Kitten
This Iran-based hacker group has been in Crowd Strike's sites since mid-January, and is best known for targeting a number of US-based defense contractors and Iranian political dissidents. Once known Ajax Security Team, this group has set its sights from hacktivism to cyber espionage and targeted attacks, InformationWeek has reported.
According to Crowd Strike, the group began targeting the defense industry earlier this year, using spear phishing emails and spoofed Microsoft Outlook Web Access pages to infiltrate the accounts of defense contractors. InformationWeek reports that the group also lured in Iranian dissidents using anti-censorship tools that had been infected with malware.
This targeting may imply that Flying Kitten is either an Iranian government entity or some private actor hired by Iran's government to take down agitators.
