On September 22, 2016, this site was forced offline for nearly four days after it was hit with “Mirai,” a malware strain that enslaves poorly secured Internet of Things (IoT) devices like wireless routers and security cameras into a botnet for use in large cyberattacks. Roughly a week after that assault, the individual(s) who launched that attack — using the name “Anna Senpai” — released the source code for Mirai, spawning dozens of copycat attack armies online.

After months of digging, KrebsOnSecurity is now confident to have uncovered Anna Senpai’s real-life identity, and the identity of at least one co-conspirator who helped to write and modify the malware.

Tens of thousands of personal and possibly proprietary databases that were left accessible to the public online have just been wiped from the Internet, replaced with ransom notes demanding payment for the return of the files. Adding insult to injury, it appears that virtually none of the victims who have paid the ransom have gotten their files back because multiple fraudsters are now wise to the extortion attempts and are competing to replace each other’s ransom notes.

Some financial instutitions are now offering so-called “cardless ATM” transactions that allow customers to withdraw cash using nothing more than their mobile phones. But as the following story illustrates, this new technology also creates an avenue for thieves to quickly and quietly convert stolen customer bank account usernames and passwords into cold hard cash. Worse still, fraudulent cardless ATM withdrawals may prove more difficult for customers to dispute because they place the victim at the scene of the crime.

One of the biggest cybersecurity stories of 2016 was the surge in online attacks caused by poorly-secured “Internet of Things” (IoT) devices such as Internet routers, security cameras, digital video recorders (DVRs) and smart appliances. Many readers here have commented with ideas about how to counter vulnerabilities caused by out-of-date software in IoT devices, so why not pitch your idea for money?

Over the past few weeks, I’ve been inundated with questions from readers asking why I haven’t written much about two stories that have consumed the news media of late: The alleged Russian hacking attacks against the Democratic National Committee (DNC) and, more recently, the discovery of malware on a laptop at a Vermont power utility that has been attributed to Russian hacker groups. I’ve avoided covering these stories mainly because I don’t have any original reporting to add to them, and because I generally avoid chasing the story of the day — preferring instead to focus on producing original journalism on cybercrime and computer security.
