The process involves injecting malicious code into the store's checkout page-directly or via third-party providers-then lurking for victims. Skimming is the interception of details during online purchases, and is often referred to as a "magecart" attack. shoppers' credit card details during online payments.Ĭybercriminals with links to a state-sponsored unit known as "Hidden Cobra" have been breaking into the websites of "large U.S retailers" and planting "skimmers" since at least May 2019, according to research released today by security firm Sansec. They will discuss how the adoption of cloud services presents new security challenges, including ideas and best practices for locking down this new architecture whether managed or in-house security is the way to go and ancillary dimensions, like SD-WAN and IaaS.Hackers with suspected ties to the North Korean regime are intercepting and stealing U.S. ET.Ī panel of experts will join Threatpost senior editor Tara Seals to discuss how to lock down data when the traditional network perimeter is no longer in place. To avoid compromise, users and administrators should follow best practices, especially maintaining up-to-date patching and antivirus enabling workstation firewalls implementing email- and download-scanning to quarantine or block suspicious attachments and files and restricting user permissions for software installations.ĭon’t miss our free Threatpost webinar, “Data Security in the Cloud,” on April 24 at 2 p.m. The group also was linked to the infamous 2014 Sony Pictures hack, for instance, as well as the SWIFT banking attacks. McAfee warned at the time that the GhostSecret campaign was carrying out data reconnaissance on a wide number of industries, including critical infrastructure, entertainment, finance, healthcare and telecommunications, in at least 17 countries. assets: A remote access tool (RAT) dubbed Joanap and a Server Message Block (SMB) worm known as Brambul – both older code that had been updated to more effectively target sensitive and proprietary information.Īlso last year, Thailand’s Computer Emergency Response Team (ThaiCERT) seized a server operated by the APT, which is part of the network used to control the global GhostSecret espionage campaign. For instance, last year the state-sponsored actors were seen using two custom families of malware against U.S. companies for some time, and continuously updates its malware strategy. Hidden Cobra/Lazarus has been a thorn in the side of U.S. Threatpost has reached out to researchers for additional analysis or the IOCs and will update this post accordingly. The alert doesn’t mention how the executable files are being disseminated. It’s not a small operation, either: 15 different IP addresses have been seen to be associated with the HOPLIGHT infrastructure, according to the warning. It can also inject code into various processes, and can download additional malware, so it could be used to disrupt regular operations and disable systems and files. HOPLIGHT is a custom affair, and a fully fledged spyware it gathers system information and can exfiltrate files and data. In addition, one file also contains a public SSL certificate, and the payload of the file appears to be encoded with a password or key and the remaining file does not contain any of the public SSL certificates, but attempts to make outbound connections and drops four additional files on a targeted system, which contain IP addresses as well as SSL certificates. “The proxies have the ability to generate fake TLS (transport layer security) handshake sessions using valid public SSL (secure sockets layer) certificates, disguising network connections with remote malicious actors.” “Seven of these files are proxy applications that mask traffic between the malware and the remote operators,” according to the advisory. The certificates are from, which is the largest search engine in Korea and provides a variety of web services to clients around the world. These files are signed with valid certificates to get around basic antivirus measures, and use encrypted connections to communicate with their command-and-control (C2) servers. In an advisory this week, the United States Computer Emergency Readiness Team (US-CERT) said that there are nine different executable files being used to spread the malware, which is the work of the North Korean government’s Hidden Cobra APT (a.k.a. companies and government agencies in active attacks, according to the U.S. A never-before-seen spyware variant called HOPLIGHT is targeting U.S.
