Golden Chickens malware developer unmasked

SecurityWeek reports that Golden Chickens malware, which has been used by the Russian Cobalt Group and FIN6 cybercrime operations, had its second developer identified by eSentire to be a Romanian named Jack, also known as Lucky and badbullzvenom. Password stealers were Jack's main specialty when he began engaging in cybercrime as a teen, releasing the Voyer malware tool for exfiltrating Yahoo instant messages between 2007 and 2008, followed by the FlyCatcher tool for keystroke logging between 2008 and 2009, and the Con password stealer for browser, instant messenger, VPN, and FTP app credential theft in 2010, according to the eSentire report. Jack was noted by researchers to have met with Golden Chickens co-developer 'Chuck from Montreal' in the dark web from late 2012 to October 2013, before proceeding to release Multiplier and VenomKit in 2015 and 2017, respectively, which were later consolidated into Golden Chickens. "Security experts assert that in 2017 the Cobalt Group used badbullzvenoms (aka: Lucky) VenomKit to deploy Cobalt Strike in attacks on banks and then they used it again in 2018," said eSentire, which noted that the malware suite was leveraged by FIN6 in 2019, the same year when the suite included the PureLocker ransomware plugin.
