The Delaware Information & Analysis Center (DIAC) has released a Cyber Alert warning that several state, local, tribal, and territorial governments have reported receiving suspicious envelopes containing malware infected CDs originating from China. Key features of these envelopes include Chinese postmarks, confusingly-worded letters with occasional Chinese characters, and SOCKO brand CD-Rs. DIAC’s alert contains sample photos of a letter, envelope, and CD. Members are encouraged to notify WaterISAC if they receive one of these envelopes.
