Man-in-the-Middle Attacks

Angie Azzi

A man-in-the-middle, or MITM, attack is cyberattack in which a hacker steals sensitive information by eavesdropping on communications between two online targets such as a user and a web application.

The Man-in-the-Middle attack resulted in the theft of $1 million from an Israeli startup. Attackers intercepted communications and manipulated transactions to divert finds. This incident highlights vulnerabilities in online security and the effectiveness of targeted cybercriminal tactics.

For this case, attackers used a Man-in-the-Middle technique to intercept and alter communications between a US business and its payment processor. They managed to redirect funds to their own account, resulting to significant financial losses for the business.

Both cases involved Man-in-the-Middle techniques, where attackers intercepted communications to manipulate transactions. Each attack led to substantial financial losses, one million in the Israeli case and over $100,000 in the US case. However, the Israeli company suffered greater financial loss compared to the US business, indicating varying scales of impact based on the targets. The Israeli case focused on a tech startup, while the US case involved a business using a payment processor, highlighting different industry vulnerabilities. The specific tactic technologies used by attackers in each case may differ, reflecting variations in execution and target weaknesses.
