How cybercriminals exploit email systems

In a world dominated by digital transactions, businesses face growing risks from sophisticated email scams. A recent case highlights how quickly criminals can exploit vulnerabilities, potentially costing companies millions.

The FTC and LA District Attorney banned NGL from under-18s, fined $5 million, citing rampant cyberbullying, and required age restrictions.

Business email compromise (BEC) scams are on the rise, targeting companies through highly deceptive tactics. These scams involve cybercriminals hacking into legitimate email accounts and tricking victims into transferring large sums of money. Recently, a small business narrowly avoided a major financial loss when a scammer posed as its owner, sending fraudulent wiring instructions to the company’s bank. Quick action by the business owner and a vigilant banker prevented the funds from being transferred.

Experts warn that BEC scams rely less on technical vulnerabilities and more on exploiting trust between businesses and their partners. Hackers often gain access through phishing attacks, installing malicious software, or guessing weak passwords. Once inside an email account, they may create hidden rules to intercept or forward messages, concealing their activities until it’s too late.

To counter these threats, cybersecurity professionals recommend measures such as enabling two-factor authentication, regularly updating passwords, and monitoring email account activity for unusual changes. Businesses are also advised to verify financial transactions using secondary methods, such as phone calls, to confirm the legitimacy of requests.

With global losses from BEC scams amounting to billions, the stakes are high. By taking proactive steps to enhance security, businesses can protect themselves from falling victim to these sophisticated schemes.
