DLL side-loading is a technique that uses malicious DLLs that spoof legitimate ones, and which relies on legitimate Windows applications to load and execute the code. The method has been abused by many advanced persistent threat (APT) groups, mostly operating out of China, with the earliest attacks observed in 2013. Cybercrime groups have since adopted the technique as well. As part of the recent attacks, DLL side-loading was used to load code that included poorly written English plaintext strings featuring politically inspired messages. Common to all of the observed samples was the use of the same program database (PDB) path, some of them containing the folder name “KilllSomeOne.” The attacks, Sophos says, targeted organizations in Myanmar, both non-governmental entities and other organizations. The targets and the characteristics of the employed malware led the security researchers to the conclusion that the attacks were launched by a Chinese threat actor. The researchers identified four different side-loading scenarios that the adversary used. In two of them, a simple shell payload was delivered, with more complex malware delivered in the other two. In some attacks, combinations of the two scenarios were used. Analysis of the attacks also revealed an effort to conceal execution, as well as apparent attempts to remove previous infections with the PlugX malware. The hackers behind these attacks, Sophos notes, are neither highly skilled, nor below average. They used simple implementations in coding and messages hidden in the code that resemble the activities of script kiddies, while their targeting and deployment resemble those of established APT groups. “Based on our analysis, it’s not clear whether this group will go back to more traditional implants like PlugX or keep going with their own code,” Sophos notes.

steven36 posted a topic in General NewsIt's the fourth time Facebook has removed Myanmar accounts for "coordinated inauthentic behavior." Facebook's fight against sham accounts in Myanmar isn't over. The social network said it pulled down more than 200 accounts, groups and pages from Myanmar for misleading users about their identity and purpose. Facebook has been subject to criticism that it didn't do enough to combat hate speech that fueled a genocide in Myanmar against the the Rohingya, a mainly Muslim group. It's the fourth network of fake accounts in Myanmar that Facebook identified this year. The social media giant said it linked some of these accounts to people associated with the Myanmar military. Some of the Facebook pages that the social network pulled down included the Myanmar Media Watch, Myanmar Muslim News and the Ethnic Regional News. The accounts posted about national and local topics, from crime and ethnic relations to entertainment and the military. "We are making progress rooting out this abuse, but as we've said before, it's an ongoing challenge," said Facebook Head of Cybersecurity Policy Nathaniel Gleicher in a Wednesday blog post. Overall, the company removed 89 Facebook accounts, 107 Facebook Pages, 15 Facebook Groups and five Instagram accounts from Myanmar. Source
