Threat hunters at Symantec have spotted signs that North Korea’s Lazarus APT group is targeting companies in the chemical sector in an ongoing cyberespionage campaign that includes fake job lures and clever social engineering.
Lazarus, which is considered a nasetion state-backed threat actor, has pulled off some of the biggest cryptocurrency heists ever seen, but the latest targeting of chemical sector and IT companies in South Korea suggests an expansion beyond big-game financial crime.
Symantec’s threat intelligence team shared notes on the latest Lazarus discovery and noted that this targeting is a continuation of a malware campaign dubbed Operation Dream Job that was previously linked to the notorious North Korean hacking group.
The company provided technical details and IOCs (indicators of compromise) on the latest malware campaigns alongside a word of warning to global businesses.

“The Lazarus group is likely targeting organizations in the chemical sector to obtain intellectual property to further North Korea’s own pursuits in this area. The group’s continuation of Operation Dream Job suggests that the operation is sufficiently successful. As such, organizations should ensure they have adequate security in place and remain vigilant for attacks such as this,” the company said.
Symantec’s Lazarus warning comes on the same day the U.S. government announced a $5 million reward for information that could help disrupt North Korean sanctions-busting activities.
“In order to support international efforts to disrupt North Korea’s illicit activities, the State Department’s Rewards for Justice (RFJ) program offers rewards of up to $5 million for information that leads to the disruption of financial mechanisms of persons engaged in certain activities that support North Korea, including money laundering, exportation of luxury goods to North Korea, specified cyber-activity and actions that support WMD proliferation,” the U.S. State Department said.

The U.S. government has also officially attributed the Ronin $600 million cryptocurrency heist to Lazarus hackers and announced sanctions against the Ethereum address that received the stolen funds.
The mega-million dollar heist is considered the second largest crypto theft of all time and included the siphoning of 173,600 Ether (ETH) and 25.5 million USD Coins stolen from the Ronin cross-chain bridge.
North Korean hacking groups have been actively targeting cryptobanks and cryptocurrency exchanges and was recently observed targeting offensive security researchers and using a fake pen-test company in attacks that employ rich social engineering tactics.
