What is Credential Harvesting?
Credential harvesting occurs through multiple attack vectors. Phishing emails lure victims to fake login pages that capture entered credentials. Malware including keyloggers records everything typed on infected devices. Social engineering tricks users into revealing passwords directly. Information-stealing malware extracts saved credentials from browsers. Attackers also purchase previously harvested credentials from dark web marketplaces and data breach repositories. The harvested credentials feed into credential stuffing attacks, account takeover attempts, and further targeted attacks. Sophisticated operations maintain large databases of credentials organized by company, industry, or service, which are then sold or traded in underground markets.
Business Impact
Harvested credentials enable attackers to access corporate systems, customer accounts, email platforms, financial services, and sensitive applications. Organizations face data breaches, unauthorized transactions, compromised business communications, and regulatory penalties. When employee credentials are harvested, attackers gain footholds for launching internal attacks, stealing intellectual property, or pivoting to additional systems. Customer credential harvesting damages trust and creates liability when accounts are misused.
Allure Security's Approach
Preventing credential harvesting requires identifying and taking down phishing sites that target your users, monitoring dark web marketplaces where credentials are sold, detecting malware campaigns aimed at your customers or employees, and implementing authentication controls that limit credential reuse. Rapid response to phishing campaigns minimizes the number of victims.
