New York, NY |Today the Department of Financial Services (DFS) issued the following industry letter to all regulated entities following recent events and the need for heightened cybersecurity precautions.
January 4, 2020
To: All Regulated Entities
Subject: Cybersecurity Risk Alert
There is currently a heightened risk of cyber attacks from hackers affiliated with the Iranian government. The Iranian government has vowed to retaliate against the United States for the death of Qassem Soleimani. Given Iranian capabilities and history, U.S. entities should prepare for the possibility of cyber attacks.
It is particularly concerning that Iran has a history of launching cyber attacks against the U.S., and the financial services industry. For instance, in 2012 and 2013, Iranian-sponsored hackers launched denial of service attacks against several major U.S. banks. And the U.S. government recently advised in June 2019 it observed “a recent rise in malicious cyber activity directed at United States industries and government agencies by Iranian regime actors and proxies,” and that Iranian attackers were increasingly using highly destructive attacks that delete or encrypt data.
DFS therefore strongly recommends that all regulated entities heighten their vigilance against cyber attacks. While currently there are no specific, credible, reports of new Iranian-sponsored cyber attacks in the past few days, all regulated entities should be prepared to respond quickly to any suspected cyber incidents. Iranian-sponsored hackers have historically relied primarily on common hacking tactics such as email phishing, credential stuffing, password spraying, and targeting unpatched devices.
DFS therefore recommends that all regulated entities ensure that all vulnerabilities are patched/remediated (especially publicly disclosed vulnerabilities), ensure that employees are adequate to deal with phishing attacks, fully implement multi-factor authentication, review and update disaster recovery plans, and respond quickly to further alerts from the government or other reliable sources. It is particularly important to make sure that any alerts or incidents are responded to promptly even outside of regular business hours – Iranian hackers are known to prefer attacking over the weekends and at night precisely because they know that weekday staff may not be available to respond immediately.
Regulated entities should also promptly notify DFS of any significant or noteworthy cyber attack. DFS’s cyber regulation requires notification “as promptly as possible but in no event later than 72 hours” after a material cybersecurity event. 23 NYCRR 500.17. And, in light of the current threat, we urge all regulated entities to notify DFS of any material incidents as soon as possible given the heightened risk, and certainly no later than the required 72 hours. This will enable DFS to disseminate information about new cyber attacks as quickly as possible.
