Most Odinaff attacks were against financial targets. It was followed by Hong Kong, Australia, the UK and Ukraine. ![]() The attacks have hit a wide range of regions, with the US the most frequently targeted. Estimates of total losses to Carbanak-linked attacks range from tens of millions to hundreds of millions of dollars.Īttacks involving Odinaff appear to have begun in January 2016. Custom malware tools, purpose built for stealthy communications ( Backdoor.Batel), network discovery, credential stealing, and monitoring of employee activity are deployed.Īlthough difficult to perform, these kinds of attacks on banks can be highly lucrative. There appears to be a heavy investment in the coordination, development, deployment, and operation of these tools during the attacks. These attacks require a large amount of hands on involvement, with methodical deployment of a range of lightweight back doors and purpose built tools onto computers of specific interest. This new wave of attacks has also used some infrastructure that has previously been used in Carbanak campaigns. These additional tools bear the hallmarks of a sophisticated attacker which has plagued the financial industry since at least 2013–Carbanak. Odinaff is typically deployed in the first stage of an attack, to gain a foothold onto the network, providing a persistent presence and the ability to install additional tools onto the target network. Organizations who provide support services to these industries are also of interest. These attacks appear to be extremely focused on organizations operating in the banking, securities, trading, and payroll sectors. ![]() Photo Credit: Ken Wolter / Shutterstock.Since January 2016, discreet campaigns involving malware called Trojan.Odinaff have targeted a number of financial organizations worldwide. You can find out more about the similarities that have been discovered over on the Symantec website. These earlier versions of WannaCry used stolen credentials to spread across infected networks, rather than leveraging the leaked EternalBlue exploit that caused WannaCry to spread quickly across the globe starting on May 12. Despite the links to Lazarus, the WannaCry attacks do not bear the hallmarks of a nation-state campaign but are more typical of a cybercrime campaign. Analysis of these early WannaCry attacks by Symantec’s Security Response Team revealed substantial commonalities in the tools, techniques, and infrastructure used by the attackers and those seen in previous Lazarus attacks, making it highly likely that Lazarus was behind the spread of WannaCry. This earlier version was almost identical to the version used in May 2017, with the only difference the method of propagation. Prior to the global outbreak on May 12, an earlier version of WannaCry (Ransom.Wannacry) was used in a small number of targeted attacks in February, March, and April. The team points to smaller-scale attacks earlier in the year which show clear links to Lazarus, as well as the reuse of code in the May attack which took the world by surprise. Researchers at Symantec found multiple instances of code reuse from earlier versions of WannaCry and Lazarus' previous attacks. But while the links to Lazarus are strong, North Korea denies that it was involved in any sort of state-sponsored attack, dismissing such claims as "a dirty and despicable smear campaign." It is thought that the group - also responsible for attacking Sony Pictures and stealing $81 million from the Bangladesh Central Bank - operated independently for personal gain.
