U.S. Carried Out Cyberattacks on Iran

www.nytimes.com/2019/06/22/us/politics/us-iran-cyber-attacks.html United States Cyber Command on Thursday conducted online attacks against an Iranian intelligence group that American officials believe helped plan the attacks against oil tankers in recent weeks, according to people briefed on the operation. The intrusion occurred the same day President Trump called off a strike on Iranian targets like radar and missile batteries. But the online operation was allowed to go forward because it was intended to be below the threshold of armed conflict using the same shadow tactics that Iran has deployed. The online attacks, which had been planned for several weeks, were ultimately meant to be a direct response to both the tanker attacks this month and the downing of an American drone this week, according to the people briefed on the operations. Multiple computer systems were targeted, according to people briefed on the operations, including those believed to have been used by an Iranian intelligence group that helped plan the tanker attacks.

DHS warns of spike in cyberattacks from Iran

www.washingtontimes.com/news/2019/jun/22/dhs-warns-spike-cyberattacks-iran/ Iranian computer hackers are ramping up attacks against U.S. targets, a top Department of Homeland Security official said Saturday. Christopher C. Krebs, the head of the DHS Cybersecurity and Infrastructure Security Agency, or CISA, issued a statement confirming recent reporting about Iranian hackers increasingly setting their sight on the U.S. as tensions flare between countries. CISA is aware of a recent rise in malicious cyber activity directed at United States industries and government agencies by Iranian regime actors and proxies, said Mr. Krebs. We will continue to work with our intelligence community and cybersecurity partners to monitor Iranian cyber activity share information, and take steps to keep America and our allies safe, he said. Iranian hackers are increasingly using wiper attacks to erase data stored on infected computers as opposed to just stealing it, Mr. Krebs added. These efforts are often enabled through common tactics like spear phishing, password spraying and credential stuffing. What might start as an account compromise, where you think you might just lose data, can quickly become a situation where youve lost your whole network, he warned. Individuals should defend themselves by exercising cybersecurity best practices and alert authorities of any suspected compromises, he said. CrowdStrike and FireEye, two private U.S. cybersecurity firms, both said Friday that they have witnessed an uptick in malicious activity in recent weeks traced to suspected Iranian government hackers.
