The techno soldiers of Kim Jong Un are growing more aggressive in defending North Korea’s supreme president against menaces from Donald Trump and South Korea.

The country’s hackers stole military programs developed by the U.S. and South Korea last year that included a highly classified” decapitation strike” against the North Korean leader, according to a South Korean lawmaker. The programmes were devised as the regime in Pyongyang steps up nuclear tests and fired long-range weapons toward the Pacific Ocean.

The episode shows North Korea’s progress in infiltrating computer systems around the world three years after its hackers allegedly stole documents issued for Sony Corp. in reprisal for the film,” The Interview .” If Kim’s cyber warriors have indeed stolen the top-secret intelligence, it creates alarms about the security of U.S.-South Korea information and the effectiveness of potential military options.

” The scheme is fundamental to conducting a conflict operation and leakage of even a small part of it is very critical ,” Rhee Cheol-hee, the ruling party lawmaker, said in a telephone interview.” How could we fight against an foe and win a war if it’s already aware of our strategy ?”

North Korea Hackers Step Up Bitcoin Attacks Amid Sanctions

North Korea has been developing cyber capabilities as trade sanctions and a debilitated domestic economy make it difficult to invest in conventional military capabilities. While Kim is dedicating the resources necessary nuclear missiles, hackers give a cost-effective style to threaten contenders that are typically reliant on technology systems.

” There is no doubt that they are using their capability in creative behaviors ,” said Fergus Hanson, head of the International Cyber Policy Centre at the Australian Strategic Policy Institute in Canberra.” Stealing battle programs is patently a good idea from a military point of view and they’re likewise monetizing their capability to get around sanctions .”

While North Korea lets internet access to only a small portion of its population, it began to train its techno soldiers in the early 1990′ s, according to South Korea’s Defense Security Command. The country probably utilizes 1,700 state-sponsored hackers, backed by more than 5,000 support staff, Hanson said.

The U.S. protected its capabilities despite the alleged hacker. In a briefing with reporters, Colonel Robert Manning, a Pentagon spokesman, wouldn’t to consider whether any violate occurred, but said the U.S. has confidence in the security of its intelligence and its ability to deal with North Korean threats.

North Korea May Fire Short-Range Rockets Next Week, Daily Says

It wasn’t immediately certain whether the strike plans allegedly stolen by North Korea could have been a decoy in the long-running conflict of espionage between the two Koreas.

North Korean hackers stimulated international headlines in 2014 when they allegedly transgressed into Sony’s Hollywood operation as it was preparing to release” The Interview ,” a Seth Rogen spy caper about gratifying the Northern korean president. Sony Chief Executive Officer Kazuo Hirai called the attack” vicious and malicious” as it led to embarrassing revelations.

Then last year, a group links between North Korea, called Bluenoroff, allegedly stole fund from Bangladesh’s central bank. In May, a group called Lazarus was linked by security researchers to a global ransomware attack that affected more than 300,000 computers.

This year, the country’s hackers appear to have stepped up their efforts to secure bitcoin and other cryptocurrencies that could be used to avoid trade restrictions. They increased strikes on exchanges in South Korea and related sites, according to a report from security researcher FireEye Inc .

” For South Korea, these targeted attacks from North Korea are not new. South Korea has fairly strong cyber security, but it faces an adversary with a significant asymmetric advantage ,” says Bryce Boland, chief engineering policeman for the Asia-Pacific region at FireEye.” North Korea has little real connectivity and relatively limited reliance on technology, attaining it less vulnerable to attacks .”

FireEye said on its website on Wednesday that hackers likely affiliated with North Korea sent phishing emails to U.S. electric companies last month for “reconnaissance” and that the security firm was able to stop them before any interruption occurred in the power supply.

North Korean diplomats and official media have denied that the country played any role in cyberattacks, including the Sony hack. Still the two attacks have inspired South Korea to elevate an army of its own cyber warriors and increase spending be addressed with the threat.

South Korea may have become a target not only due to its close proximity to Pyongyang and shared language and the two countries says North Korea has carried out six major cyber attacks on its institutions since 2009. It includes an attack on one of South Korea’s largest banks, Nonghyup, that left about 30 million account owners unable to withdraw fund for periods in 2011.

“What’s embarrassing is that this was caused by an ludicrous mistake by our own military ,” said Rhee, who added he showed the hacker with defense officials.” They’re not supposed to move and save such important files in PCs. This is an incident that could have been avoided if the military forces abided by the basic security regulations .”
