Banking Trojan Abuses Pinterest in C&C Routines

Last summer Trend Micro observed online banking Trojans that were targeting South Korean banks. Now, compromised sites that contain exploit kits are delivering banking Trojans to site visitors. Some of the banks being targeted include Hana Bank, Nonghyup Bank, the Industrial Bank of Korea (IBK), Shinhan Bank, Woori Bank, Kookmin Bank, and the Consumer Finance Service Center. Once a customer has been infected with malware and is redirected to a phishing site that looks like a legitimate banking website, the criminals are able to steal their credentials.

One interesting characteristic of this particular Trojan is that it is using Pinterest as its command-and-control server to redirect users to various spoofed banking sites,

North Korea Denies Role in Smartphone Hacking incident of South Korea

North Korea’s state media on Monday blasted South Korea’s spy agency for alleging that Pyongyang hacked tens of thousands of smartphones in the South using malware disguised in mobile gaming apps.

The South’s National Intelligence Service (NIS) said in a report to parliament last week that the North attempted to hack more than 20,000 South Korean smartphones between May and September.

The agency said it had worked with the owners of South Korean websites and government officials to remove the applications and block hacking channels.

Pyongyang’s official website Uriminzokkiri accused the NIS of fabricating the report to distract attention from a standoff over South Korean activists who send leaflets critical of the North’s regime across the border by balloon.
