Its a truism in cyber security that behind every great hack often lies a string of bad decisions and missed opportunities. Its also true that when you dig into the details of damaging cyber incidents, the root causes are personal and psychological as often as they are technical in nature. Organizations -even sophisticated and wealthy organizations – end up making bad decisions for all the wrong reason: failing to properly assess their risk, or pursuing short term savings when long term investment is needed.

Home Depot said it is investigating “some unusual activity” on its networks and working with “banking partners and law enforcement,” after security blogger Brian Krebs named the company as a common thread connecting a trove of stolen credit card accounts that have appeared in underground forums.

A group representing the Uyghurs,a persecuted religious minority in China, faces unrelenting, targeted cyber attacks that appear aimed at stealing sensitive data and otherwise undermining the group’s activity, according to a new study by researchers at Northeastern University in Boston as well as the Max Planck Institute for Software Systems and the National University of Singapore. A study of more than 1,400 suspicious email messages sent to members of groups representing the Uyghur minority found that more than three quarters of the messages contained malicious attachments. The messages targeted 724 individuals at 108 separate organizations. Moreover, researchers found overlap between the individuals associated with the Uyghur World Contress (UWC) and western targets such as the New York Times and U.S. embassies. The study, “A Look at Targeted Attacks Through the Lense of an NGO” is being presented at the UNENIX Security Conference in San Diego on August 21. (A copy of the full paper is […]
