North Korean state-sponsored threat actors have been attributed to a cyber espionage campaign targeting the defense sector across the world. In a joint advisory published by Germany's Federal Office for the Protection of the Constitution (BfV) and South Korea's National Intelligence Service (NIS), the agencies said the goal of the attacks is to plunder advanced defense technologies in a "cost-effective" manner. "The regime is using the military technologies to modernize and improve the performance of conventional weapons and to develop new strategic weapon systems including ballistic missiles, reconnaissance satellites and submarines," they  noted .  The infamous Lazarus Group has been blamed for one of the two hacking incidents, which involved the use of social engineering to infiltrate the defense sector as part of a long-standing operation called  Dream Job . The campaign has been  ongoing since August 2020  over several waves. In these attacks, the ...

North Korean threat actors are actively exploiting a critical security flaw in JetBrains TeamCity to opportunistically breach vulnerable servers, according to Microsoft. The attacks, which entail the exploitation of  CVE-2023-42793  (CVSS score: 9.8), have been  attributed  to Diamond Sleet (aka Labyrinth Chollima) and Onyx Sleet (aka Andariel or Silent Chollima). It's worth noting that both the threat activity clusters are part of the infamous North Korean nation-state actor known as  Lazarus Group . In one of the two attack paths employed by Diamond Sleet, a successful compromise of TeamCity servers is followed by the deployment of a known implant called  ForestTiger  from legitimate infrastructure previously compromised by the threat actor. A second variant of the attacks leverages the initial foothold to retrieve a malicious DLL (DSROLE.dll aka RollSling or Version.dll or FeedLoad) that's loaded by means of a technique referred to as DLL searc...

The latest Palo Alto Networks Unit 42 Cloud Threat Report found that sensitive data is found in 66% of cloud storage buckets. This data is vulnerable to ransomware attacks. The SANS Institute recently reported that these attacks can be performed by abusing the cloud provider's storage security controls and default settings. "In just the past few months, I have witnessed two different methods for executing a ransomware attack using nothing but legitimate cloud security features," warns Brandon Evans, security consultant and SANS Certified Instructor. Halcyon disclosed an attack campaign that leveraged one of Amazon S3's native encryption mechanisms, SSE-C, to encrypt each of the target buckets. A few months prior, security consultant Chris Farris demonstrated how attackers could perform a similar attack using a different AWS security feature, KMS keys with external key material, using simple scripts generated by ChatGPT. "Clearly, this topic is top-of-mind for both threat actors and ...
