Businesses that use gateway security appliances to protect Research In Motion’s BlackBerry communications servers could be subject to attacks based on the planned release of exploit code by a high-profile malware researcher. According to a warning released by network security applications and device provider Secure Computing, organizations with their BlackBerry servers installed behind their gateway intrusion detection boxes could be compromised when researcher Jesse D’Aguanno, a consultant with risk management experts Praetorian Global, of Placerville, Calif., releases his code the week of Aug. 14. D’Aguanno first revealed his vulnerability exploit on Aug. 5 at the Defcon hacker convention in Las Vegas.
