While best known for their bodyguards and snipers, the U.S. Secret Service has accumulated an impressive suite of advanced cyber capabilities.

In this post, we review some of the cyber techniques the Secret Service employs to ensure the safety and security of US leaders.

Advanced Threat Intelligence

Aside from physically protecting government leaders, the Secret Service utilizes sophisticated custom-built threat intelligence platforms to monitor and analyze potential cyber threats. These platforms aggregate data from various sources, including OSINT, dark web monitoring, government partners, and private threat feeds. The intelligence gathered helps in identifying emerging threats and preventing potential cyberattacks against government officials or infrastructure.

Example: During the 2021 inauguration of President Joe Biden, the Secret Service scanned the web for potential threats, employing keyword detection (against terms like "inauguration," "attack," "hack," and "disrupt"), and performed behavioural analysis against predetermined suspicious patterns.

The Secret Service and its partners successfully disrupted several threat actors before they could execute their plans. This involved taking down certain online accounts, blocking communication channels, and deploying countermeasures to neutralize planned attacks.

Encrypted Communications and Secure Travel Protocols

The Secret Service employs highly encrypted communication systems to protect against eavesdropping and interception. These systems ensure that all digital communications, including phone calls, emails, and texts, remain confidential.

During high-stakes negotiations and international summits, the Secret Service is responsible for ensuring that all communication devices are secure, employing measures such as encrypted communication channels and secure meeting environments.

When the President travels, the Secret Service extends its cybersecurity measures to the entire travel infrastructure. This includes securing the digital systems of Air Force One, motorcades, and temporary locations.

Example: During President Obama's visit to Cuba in 2016, these encrypted systems were crucial in maintaining secure communication channels in a region with limited cybersecurity infrastructure. Similarly, during President Trump's 2018 summit with Kim Jong-un, robust cybersecurity protocols were in place to protect all digital communications and infrastructure involved in the trip.

Digital Forensics

The Secret Service's digital forensics teams are trained to respond to and investigate cyber incidents swiftly. Using advanced forensic tools, they can trace cyberattacks, identify perpetrators, and secure digital evidence for further action.

Example: In 2014, the White House's unclassified computer network experienced a sophisticated cyber intrusion. The intrusion was initially detected by the White House's IDS, which flagged unusual network activity. Upon detection, the Secret Service's digital forensics team collected data from the affected systems. Their subsequent log analysis revealed that the attackers had gained access through a spear-phishing campaign, targeting White House staff with malicious emails.

Through their forensic investigation, the team identified digital footprints that pointed to the involvement of state-sponsored actors. Indicators of compromise (IOCs) such as IP addresses, malware signatures, and attack patterns were matched with known tactics of Russian cyber espionage groups.

Collaborative efforts with intelligence agencies helped confirm the attribution to Russian hackers.

Disinformation and Social Media Monitoring

The Secret Service employs advanced algorithms and AI to monitor social media and other online platforms for disinformation campaigns that could pose a threat to national security and the safety of the President.

In the past, they've collaborated directly with major social media companies, including Facebook, Twitter, and Google, to share information about disinformation trends and coordinated efforts to counteract false narratives. This partnership enabled the swift removal of misleading content and the suspension of accounts involved in spreading disinformation.

Example: In preparation for significant events such as State of the Union addresses, the Secret Service monitors social media for disinformation and threats, allowing them to pre-emptively address potential security concerns.

Conclusion

The U.S. Secret Service employs a wide range of cyber capabilities in their mission to protect national leaders. Through advanced threat intelligence, secure communications, digital forensics, and robust collaboration, the Secret Service compliments and extends their kinetic expertise in the digital space. However, in light of July 15th's assassination attempt of President Trump, the question must be raised: is it enough?
