On Tuesday the US attorney for the southern district of New York unsealed criminal charges against three Chinese hackers who successfully breached the networks of some unnamed Wall Street law firms and obtained confidential information that allowed them to make a $4 million profit, reported the Financial Times. “Once inside, the trio targeted the email accounts of senior partners who worked on high-profile mergers and acquisitions — and then bought stock in at least five publicly traded companies before deals were announced.” Manhattan U.S. attorney Preet Bharara referred to the case as a “wake-up call for law firms around the world,” reported the Wall Street Journal. The New York Times also wrote about the case.
