#ESETresearch A year ago, a signed Mach-O executable disguised as a job description was uploaded to VirusTotal from Singapore 🇸🇬. Malware is compiled for Intel and Apple Silicon and drops a PDF decoy. We think it was part of #Lazarus campaign for Mac. @pkalnai @marc_etienne_ 1/8
The document, named BitazuCapital_JobDescription.pdf, reminds a strong similarity with a lure from Lazarus attacks using 2 TOY GUYS code-signing certificates for Windows, targeting aerospace and defense industries. welivesecurity.com/wp-content/upl… 2/8
Both decoys are PDF v1.5 documents produced by Microsoft Word 2016. They are obviously not identical, as one uses Colonna MT font while the other uses Calibri, but the title and ornaments on the front page have the same colors (#569bd5 and #aacc5db). 3/8
