Law firms usually manage to keep the public in the dark when it comes to data breaches and hacking attacks. But not this week.
The Wall Street Journal reported Tuesday that hackers had gained access to the computer networks of law firms working on M&A deals, including Cravath, Swaine & Moore and Weil, Gotshal & Manges. A Weil spokeswoman declined to comment, but Cravath confirmed that the firm identified a “limited breach of its IT systems” in the summer of 2015.
“We have worked closely with law enforcement authorities who have jurisdiction over this matter, and we are not aware that any of the information that may have been accessed has been used improperly,” the firm said in a statement, adding that it beefed up its security measures after the breach.
Also this week, Crain’s Chicago Business reported that dozens of law firms were targeted by a Russian hacker seeking information on M&A deals. The cybercriminal, going by the name of “Oleras,” was discovered soliciting help from other hackers to try to gain access to computer systems at 48 firms, nearly all of which are among The Am Law 100.
