United States Department of Homeland Security investigators say they’ve thwarted hundreds of ransomware cyberattacks, often before they occurred, and have seized billions of extorted crypto since 2021.
US agencies were the top targets, accounting for 21% of the disrupted hacks, more than any business sector, Mike Prado, the deputy assistant director of the Homeland Security Investigations (HSI) Cyber Crimes Center, told Bloomberg in an Oct. 4 <a data-ct-non-breakable="null" href="https://www.bloomberg.com/news/newsletters/2024-10-04/cyber-cops-stopped-500-ransomware-hacks-since-2021-dhs-says" rel="noopener noreferrer nofollow" target="null" text="null" title="null">report</a>.

According to Prado, HSI is taking a proactive approach to disrupting ransomware attacks by “keeping a finger on the pulse” of cybercrime and the <a data-ct-non-breakable="null" href="https://cointelegraph.com/learn/pig-butchering-crypto-scams-how-to-combat-them" rel="noopener noreferrer nofollow" target="null" text="null" title="null">constantly evolving tactics</a> used by criminals.&nbsp;
Agents analyze internet traffic, look for signs of malicious activity and monitor software vulnerabilities that ransomware gangs could use to exploit an organization’s security.&nbsp;
The goal is to discover when attacks are about to happen, in some cases before the breach occurs, and to prevent it.&nbsp;
As a result of these actions, Prado says there are several “groups that we have our eyes on,” with gangs outside of the US “continuously probing ways to obtain cryptocurrency.”
Still, he said the approach can be a double-edged sword, as building a case against hackers whose attacks are blocked by HSI can be difficult.&nbsp;
If an attack is imminent, Prado says HSI notifies government agencies, companies and other potential victims while coordinating with agents across 235 field offices in the US, local police departments and other federal agencies.
