Cyberattacks supposedly originating from China have raised alarms in recent weeks, but U.S. businesses and government agencies should worry as much about Iran and North Korea, a group of cybersecurity experts said.
China and Russia have significantly more sophisticated cyberthreat capabilities than do Iran and North Korea, but the two smaller countries are cause for concern in international cybersecurity discussions, the experts told a U.S. House of Representatives subcommittee last wek.
Iranian authorities have blocked the use of most virtual private network (VPNs) to stop people in the country from circumventing the government's internet filter, three months before the country holds its presidential election.
"Within the last few days illegal VPN ports in the country have been blocked," Ramezanali Sobhani-Fard, the head of the Iranian parliament's information and communications technology committee, told Mehr news agency, according to Reuters. "Only legal and registered VPNs can from now on be used."
Researchers have uncovered a never-before-seen version of Stuxnet. The discovery sheds new light on the evolution of the powerful cyberweapon that made history when it successfully sabotaged an Iranian uranium-enrichment facility in 2009.
The attackers hit one U.S. bank after the next. As in so many previous attacks, dozens of online banking sites slowed, hiccupped or ground to a halt before recovering several minutes later.
But there was something disturbingly different about the wave of online attacks on U.S. banks in recent weeks. Security researchers say that instead of exploiting individual computers, the attackers engineered networks of computers in data centers, transforming the online equivalent of a few yapping Chihuahuas into a pack of fire-breathing Godzillas.
A new piece of malware that deletes entire partitions and user files from infected computers has been found in Iran, according to an alert issued by Maher, Iran's Computer Emergency Response Team Coordination Center (CERTCC).
