![]() “For now, more research is required into older versions of Wannacry,” Kaspersky Lab said in a report published Monday. ![]() They’ve hardly been as successful generating the same revenue with WannaCry, which at last count has collected 40 Bitcoin, which translates to about $71,000 USD. ![]() All but $80 million had been recovered once the attack was made public.Īt this year’s Kaspersky Lab Security Analyst Summit, researchers from Kaspersky, BAE Systems and SWIFT talked shared more details about Lazarus’ activities, including a group within the APT it called Bluenoroff dedicated to stealing money in order to fund Lazarus’ activities. Last year’s massive heist starting at the Bangladesh Bank abused the organization’s connection to the SWIFT network to make close to a $1 billion in fraudulent transactions. The group stole and leaked movie scripts, sensitive corporate emails and much more private data from the company, and also used wiper malware to damage internal workstations at Sony Pictures Entertainment. Lazarus’ history is a notorious one, starting with the 2014 Sony hack, which it is alleged to have pulled off. Shared code between an early, Feb 2017 Wannacry cryptor and a Lazarus group backdoor from 2015 found by from Google. Similitude between #WannaCry and Contopee from Lazarus Group ! thx – Is DPRK behind #WannaCry ? /uJ7TVeATC5 Since then, researchers at Kaspersky Lab, Symantec and Comae Technologies Matt Suiche have confirmed the similarities, adding fuel to the possible connection between North Korea and the current ransomware outbreak. Mehta’s tweet shows a code array shared between a Lazarus sample from February 2015 and an early version of WannaCry that surfaced in February of this year. Lazarus is alleged to be behind the 2016 SWIFT attacks in Bangladesh and a number of other incursions against other banks, casinos and cryptocurrency operations.ĩc7c7149387a1c79679a87dd1ba755bc 0x402560, 0x40F598Īc21c8ad899727137c4b94458d7aa8d8 0x10004ba0, 0x10012AA4 #WannaCryptAttribution In the meantime on Monday afternoon, Google researcher Neel Mehta, the same researcher who discovered the Heartbleed vulnerability in 2014, posted a tweet indicating a connection between WannaCry and the Lazarus APT. It then determines the public IP address of the victim and download the mining instructions, cryptominer, and cleanup tools.” “Once running, Adylkuzz will first stop any potential instances of itself already running and block SMB communication to avoid further infection. The DoublePulsar backdoor then downloads and runs Adylkuzz from another host,” Kafeine said. “Upon successful exploitation via EternalBlue, machines are infected with DoublePulsar. More than 20 virtual private servers are scanning the internet for targets running port 445 exposed, the same port used by SMB traffic when connected to the internet, and the same port abused by EternalBlue and DoublePulsar. Kafeine said the Adylkuzz attacks pre-date WannaCry with the first samples going back to April 24. ![]() Once Adylkuzz infects a machine, it mines the open source Monero cryptocurrency, which goes to great lengths to obfuscate its blockchain information, making it a challenge to trace activity. Kafeine, a well-known exploit researcher who works for Proofpoint, said Monday that this attack could be greater in scale than WannaCry, which spread worldwide on Friday infecting Windows machines still unpatched against the SMBv1 vulnerabilities exploited by the NSA’s EternalBlue exploit and DoublePulsar rootkit and backdoor. As the first inkling of attribution emerged in the WannaCry ransomware outbreak, researchers found another attack using the same leaked NSA attack tools to spread the Adylkuzz cryptocurrency miner.
