How Coinbase Phishers Steal One-Time Passwords

October 13, 2021

A recent phishing campaign targeting Coinbase users shows thieves are getting cleverer about phishing one-time passwords (OTPs) needed to complete the login process. It also shows that phishers are attempting to sign up for new Coinbase accounts by the millions as part of an effort to identify email addresses that are already associated with active accounts.

REvil Ransomware Gang Starts Auctioning Victim Data

June 2, 2020

The criminal group behind the REvil ransomware enterprise has begun auctioning off sensitive data stolen from companies hit by its malicious software. The move marks an escalation in tactics aimed at coercing victims to pay up — and publicly shaming those don’t. But it may also signal that ransomware purveyors are searching for new ways to profit from their crimes as victim businesses struggle just to keep the lights on during the unprecedented economic slowdown caused by the COVID-19 pandemic.

Ransomware Gangs Now Outing Victim Businesses That Don’t Pay Up

December 16, 2019

As if the scourge of ransomware wasn’t bad enough already: Several prominent purveyors of ransomware have signaled they plan to start publishing data stolen from victims who refuse to pay up. To make matters worse, one ransomware gang has now created a public Web site identifying recent victim companies that have chosen to rebuild their operations instead of acquiescing to their tormentors.

Transcription Service Leaked Medical Records

April 23, 2018

MEDantex, a Kansas-based company that provides medical transcription services for hospitals, clinics and private physicians, took down its customer Web portal last week after being notified by KrebsOnSecurity that it was leaking sensitive patient medical records — apparently for thousands of physicians.

U.K. Hospitals Hit in Widespread Ransomware Attack

May 12, 2017

At least 16 hospitals in the United Kingdom are being forced to divert emergency patients today after computer systems there were infected with ransomware, a type of malicious software that encrypts a victim’s documents, images, music and other files unless the victim pays for a key to unlock them.

It remains unclear exactly how this ransomware strain is being disseminated and why it appears to have spread so quickly, but there are indications the malware may be spreading to vulnerable systems through a security hole in Windows that was recently patched by Microsoft.

Before You Pay that Ransomware Demand…

December 22, 2016

A decade ago, if a desktop computer got infected with malware the chief symptom probably was an intrusive browser toolbar of some kind. Five years ago you were more likely to whacked by a banking trojan that stole all your passwords and credit card numbers. These days if your mobile or desktop computer is infected what gets installed is likely to be “ransomware” — malicious software that locks your most prized documents, songs and pictures with strong encryption and then requires you to pay for a key to unlock the files.

Ransomware Getting More Targeted, Expensive

September 15, 2016

I shared a meal not long ago with a source who works at a financial services company. The subject of ransomware came up and he told me that a server in his company had recently been infected with a particularly nasty strain that spread to several systems before the outbreak was quarantined. He said the folks in finance didn’t bat an eyelash when asked to authorize several payments of $600 to satisfy the Bitcoin ransom demanded by the intruders: After all, my source confessed, the data on one of the infected systems was worth millions — possibly tens of millions — of dollars, but for whatever reason the company didn’t have backups of it.

This anecdote has haunted me because it speaks volumes about what we can likely expect in the very near future from ransomware — malicious software that scrambles all files on an infected computer with strong encryption, and then requires payment from the victim to recover them.
