An Interview With the Target & Home Depot Hacker

In December 2023, KrebsOnSecurity revealed the real-life identity of Rescator, the nickname used by a Russian cybercriminal who sold more than 100 million payment cards stolen from Target and Home Depot between 2013 and 2014. Moscow resident Mikhail Shefel, who confirmed using the Rescator identity in a recent interview, also admitted reaching out because he is broke and seeking publicity for several new money making schemes.

Ten Years Later, New Clues in the Target Breach

‘Spam Nation’ Villain Vrublevsky Charged With Fraud

Pavel Vrublevsky, founder of the Russian payment technology firm ChronoPay and the antagonist in my 2014 book “Spam Nation,” was arrested in Moscow this month and charged with fraud. Russian authorities allege Vrublevsky operated several fraudulent SMS-based payment schemes, and facilitated money laundering for Hydra, the largest Russian darknet market.

A Shakeup in Russia’s Top Cybercrime Unit

A chief criticism I heard from readers of my book, Spam Nation: The Inside Story of Organized Cybercrime, was that it dealt primarily with petty crooks involved in petty crimes, while ignoring more substantive security issues like government surveillance and cyber war. But now it appears that the chief antagonist of Spam Nation is at the dead center of an international scandal involving the hacking of U.S. state electoral boards in Arizona and Illinois, the sacking of Russia’s top cybercrime investigators, and the slow but steady leak of unflattering data on some of Russia’s most powerful politicians.
