Hunters

Malware hunters, also known as bug hunters, are cybersecurity professionals who identify and address vulnerabilities in computer systems. In 2023, these experts earned $1,038,250 for identifying 58 unique zero-day vulnerabilities at Pwn2Own Toronto, a high-profile hacking event. This success underscores the critical role that these professionals play in securing digital infrastructure and protecting against malicious software, or malware. Companies such as Trend have been pioneering AI innovations since 2005 to support these security operations center (SOC) analysts and threat hunters, streamlining their operations and enhancing risk response. In recent years, hacktivist groups like Anonymous Venezuela and Cyber Hunters have taken a more active role in political conflicts, as demonstrated by their attacks on the Venezuelan government following the contested presidential elections on July 28th, 2024. Meanwhile, other groups like Hunters International have shifted their focus towards financial gain. Using a malware called SharpRhino, they establish control over targeted systems to launch sophisticated ransomware attacks. These attacks are not limited to any specific sector or region but are opportunistic in nature. The group also employs tactics such as data exfiltration before file encryption, changing file extensions to .locked, and guiding victims to a chat portal on the Tor network for payment instructions. Hunters International, linked to Russia, has shown progression in its tactics. This group acquired the SharpRhino malware from its original owners, who disbanded after international law enforcement intervened. Researchers from Quorum Cyber revealed that Hunters International has been active since October of the previous year and is deploying Hive ransomware. This evolution of ransomware groups highlights the constant advancements in cyber threats and the need for continuous vigilance and innovation in cybersecurity.
