Cybersecurity researchers from Citizen Lab recently spotted PDF files advertising hacking services, on websites belonging to numerous U.S. government agencies and educational institutions.
As reported by TechCrunch late last week, the PDFs were found on .gov websites belonging to California, North Carolina, New Hampshire, and at least three more states, as well as at least five counties and administrative centers.
Universities such as UC Berkeley, Stanford, Yale, UC San Diego, and countless others, are also said to have had their websites compromised. Spain’s Red Cross, defense contractor Rockwell Collins, as well as an unnamed Irish tourism company, were also affected.
In the PDFs, the threat actors advertise various services, including the ability to hack into social media accounts such as Instagram, Facebook, or Snapchat. They also advertise computer game cheats and fake follower generation. Interested parties are invited to open websites listed in the PDFs.
