![]() ![]() The takeover of Emotet by WIZARD SPIDER impressively shows how resilient the eCrime milieu has become by now.” Emotet malware phishing campaign detected WIZARD SPIDER is a sophisticated eCrime group whose arsenal also includes malware such as Ryuk, Conti, and Cobalt Strike. “As we suspected, the dismantling of the Emotet network by Europol in January 2021 only had a temporary effect. In fact, more may wonder why it took so long.”Īdam Meyers, SVP of Intelligence at CrowdStrike, also confirmed the return of Emotet after acquisition by cybercrime group WIZARD SPIDER. It doesn’t come as a surprise that Emotet resurfaced. You can be sure that those that helped to take it down the first time are keeping watch. “It will take some time to see how Emotet rebuilds, and whether it can become the “world’s most dangerous malware” again. It is too early to tell what this new version of Emotet will look like. The first version’s takedown required collaboration between many companies and countries. “Its design led to a more redundant system than most malware. Security Evangelist and Chief Architect, Community Services at Team Cymru. “Emotet was different than most access-as-a-service providers,” said James Shank, Sr. The researchers advised network administrators to block the IP addresses to prevent compromise by the resurgent Emotet malware variant.Īccording to former Microsoft researcher Kevin Beaumont, the new version of Emotet malware was better and possibly created by threat actors with the original source code.Īdvanced Intel’s researcher Vitali Kremez also noted that the initial takedown did not prevent the threat actors from accessing the Emotet source code and creating a new malware variant and its infrastructure. At least 246 infected devices were already working as C2 servers. The website also discovered that the operators had expanded the list of C2 servers from nine to fourteen in 24 hours, indicating that they were gearing up for an activity. ![]() However, the servers were strikingly different from those seized in January, suggesting completely new infrastructure. The Malware tracking website Abuse.ch published a list of Emotet malware command-and-control servers. ![]() Notably, Cryptolaemus researchers found that Emotet operators were trying to reconstruct by leveraging TrickBot’s existing infrastructure in “Operation Reacharound.” They also noted that the new variant contains seven commands while its predecessor had just three to four. Enterprises have to continue to be on the alert for malware that is delivered by known bad actors in order to combat its effects.” “While it is readily identifiable, the combination of Trickbot with Emotet is a combination that still has the ability to infect systems that aren’t well protected. “Emotet is one of the most popular forms of malware in the past, and clearly still has some staying power,” said Saryu Nayyar, CEO at Gurucul. However, Ebach observed that the new Emotet malware leveraged HTTPS traffic with a self-signed server certificate. The variant also used flattened control flows for code obfuscation as previously observed in the former Emotet malware. Additionally, he found that the traffic associated with the sample was similar to one that Kaspersky associated with Emotet malware. G DATA security researcher Luca Ebach observed TrickBot distributing an Emotet windows dynamic library (DLL) targeting previously infected computers.Īccording to his November 15 blog post, Ebach noted that the sample was just recently compiled on November 14 before distribution. ![]() New Emotet malware variant leverages existing TrickBot infrastructure to reboot ![]()
