Vexday analysis

Patchwork (também conhecido como Hangover Group, Dropping Elephant, Chinastrats, MONSOON e Operation Hangover) é um grupo de espionagem cibernética observado pela primeira vez em dezembro de 2015, com evidências circunstanciais que sugerem origem indiana ou alinhamento pró-Índia. O grupo tem como alvos preferenciais agências governamentais e entidades diplomáticas, e parte significativa do código utilizado em suas operações foi copiada de fóruns públicos online. Em março e abril de 2018, o Patchwork conduziu campanhas de spearphishing direcionadas a grupos de think tank nos Estados Unidos. O grupo possui 41 técnicas documentadas no MITRE ATT&CK (identificador G0040) e 7 CVEs atribuídas.
