Attackers don't just watch your passwords anymore. They're buying all sorts of stolen access on the dark web to speak into your accounts. My name is Adrian. I've been in the Hunter's office for two years. I am a security operation analyst. What is Infostilla malware? Infostilla malware is a type of malicious software that collects credentials, financial information, and sensitive data from victims endpoints. Historically, threat actors used the Inflowstealer to steal email and bank credentials, but the Inflowstealer ecosystem is a lot more complex these days. Targeting a wide range of credentials, We're talking about fast, sneaky access that bypasses login and MFA prompts in corporate environments, tokens, API keys, MFA keys, crypto wallets, and the list goes on. What are Infosteer logs? Infosteer logs are the raw bulk data collected by the malware. They're sold on underground marketplaces and private telegram channels. The cost of the Infosteer data varies depending on data quality, the victim's geolocation, and the data type. Typical logs go from five to twenty five dollars. But logs with Fortune five hundred domain credentials, valid Microsoft three sixty five sessions, Slack or Okta tokens, or access to developer tools range from a hundred to five hundred dollars. What does this mean for defenders? Here's a look at some, but not all, hands on keyboard things threat actors can do with stolen info stealer data. They use stolen passwords for credential stuffing. They know people reuse passwords across accounts, so a ten dollar set of credentials to one account might easily open the door to several others. They use stolen tokens to launch slash and hijacking attacks, a form of dangerous persistent access. They target developer environments for immediate and deep access to corporate environments. They sell bundles of stolen credentials or add on services and tools to other threat actors to increase their profit margin. Summing this up, Infosealer malware is an initial access technique that supports bigger attacks, including ransomware, extortion, and data theft. It collects credentials, financial information, and sensitive data from victims. Infosealer data often lets attackers bypass credential logins and MFA, especially in corporate environments, creating an unwanted window of persistence. And that's how Infostealer malware exploits your endpoints and identities for profit and unauthorized access.
