U.S. Secret Service Warns ID Thieves are Abusing USPS’s Mail Scanning Service

A year ago, KrebsOnSecurity warned that “Informed Delivery,” a new offering from the U.S. Postal Service (USPS) that lets residents view scanned images of all incoming mail, was likely to be abused by identity thieves and other fraudsters unless the USPS beefed up security around the program and made it easier for people to opt out.

Busting SIM Swappers and SIM Swap Myths

KrebsOnSecurity recently had a chance to interview members of the REACT Task Force, a team of law enforcement officers and prosecutors based in Santa Clara, Calif. that has been tracking down individuals engaged in unauthorized “SIM swaps” — a complex form of mobile phone fraud that is often used to steal large amounts of cryptocurrencies and other items of value from victims.

How Do You Fight a $12B Fraud Problem? One Scammer at a Time

The fraudsters behind the often laughable Nigerian prince email scams have long since branched out into far more serious and lucrative forms of fraud, including account takeovers, phishing, dating scams, and malware deployment. Combating such a multifarious menace can seem daunting, but in truth it calls for concerted efforts to tackle the problem from many different angles.

Who Is Agent Tesla?

A powerful, easy-to-use password stealing program known as Agent Tesla has been infecting computers since 2014, but recently this malware strain has seen a surge in popularity — attracting more than 6,300 customers who pay monthly fees to license the software. Although Agent Tesla includes a multitude of features designed to help it remain undetected on host computers, the malware’s apparent creator seems to have done little to hide his real-life identity.
