Security experts warn of cyberattacks after US killing of top Iranian general
Iran’s retaliation for the United States’ targeted killing of its top general is likely to include cyberattacks, security experts warned Friday. “There are opportunities for them to cause real disruption and destruction.” Iran has been doing a lot of probing of critical U.S. industrial systems in recent years — trying to gain access — but has limited its destructive attacks to targets in the Middle East, experts say. “But we haven’t actually seen it.” Robert M. Lee, chief executive of Dragos Inc., which specializes in industrial control system security, said Iranian hackers have been very aggressive in trying to gain access to utilities, factories, and oil and gas facilities. The top cybersecurity official at the Department of Homeland Security, Christopher Krebs, urged companies and government agencies to refresh their knowledge of Iranian state-backed hackers’ past exploits and methods after Soleimani’s death was announced. In June, Krebs warned of a rise in malicious Iranian cyber activity, particularly attacks using common methods like spear-phishing that could erase entire networks: “What might start as an account compromise, where you think you might just lose data, can quickly become a situation where you’ve lost your whole network.” Wysopal said the Iranians are apt to have learned a lot from the 2017 NotPetya attack, which the U.S. and Britain have attributed to state-backed Russian hackers and which caused at least $10 billion in damage globally.
