Study: Ransomware, Data Breaches at Hospitals tied to Uptick in Fatal Heart Attacks

November 7, 2019

Hospitals that have been hit by a data breach or ransomware attack can expect to see an increase in the death rate among heart patients in the following months or years because of cybersecurity remediation efforts, a new study posits. Health industry experts say the findings should prompt a larger review of how security — or the lack thereof — may be impacting patient outcomes.

NCR Barred Mint, QuickBooks from Banking Platform During Account Takeover Storm

November 3, 2019

Banking industry giant NCR Corp. [NYSE: NCR] late last month took the unusual step of temporarily blocking third-party financial data aggregators Mint and QuicBooks Online from accessing Digital Insight, an online banking platform used by hundreds of financial institutions. That ban, which came in response to a series of bank account takeovers in which cybercriminals used aggregation sites to surveil and drain consumer accounts, has since been rescinded. But the incident raises fresh questions about the proper role of digital banking platforms in fighting password abuse.

Takeaways from the $566M BriansClub breach

October 29, 2019

Reporting on the exposure of some 26 million stolen credit cards leaked from a top underground cybercrime store highlighted some persistent and hard truths. Most notably, that the world’s largest financial institutions tend to have a much better idea of which merchants and which bank cards have been breached than do the thousands of smaller banks and credit unions across the United States. Also, a great deal of cybercrime seems to be perpetrated by a relatively small number of people.

MyPayrollHR CEO Arrested, Admits to $70M Fraud

September 27, 2019

Earlier this month, employees at more than 1,000 companies saw one or two paycheck’s worth of funds deducted from their bank accounts after the CEO of their cloud payroll provider absconded with $35 million in payroll deposits from customers. On Monday, the CEO was arrested and allegedly confessed that the diversion was the last desperate gasp of a financial shell game that earned him $70 million over several years.

Before He Spammed You, this Sly Prince Stalked Your Mailbox

September 18, 2019

A reader forwarded what he briefly imagined might be a bold, if potentially costly, innovation on the old Nigerian prince scam that asks for help squirreling away millions in unclaimed fortune: it was sent via the U.S. Postal Service, with a postmarked stamp and everything.

In truth these “advance fee” or “419” scams- – so-called because they violate section 419 of the criminal code of Nigeria where many such lures originate — predate email and have circulated via postal mail in various forms and countries over the years.

NY Payroll Company Vanishes With $35 Million

September 11, 2019

MyPayrollHR, a now defunct cloud-based payroll processing firm based in upstate New York, abruptly ceased operations this past week after stiffing employees at thousands of companies. The ongoing debacle, which allegedly involves malfeasance on the part of the payroll company’s CEO, resulted in countless people having money drained from their bank accounts and has left nearly $35 million worth of payroll and tax payments in legal limbo.

Federal prosecutors in California have filed criminal charges against four employees of Adconion Direct, an email advertising firm, alleging they unlawfully hijacked vast swaths of Internet addresses and used them in large-scale spam campaigns. KrebsOnSecurity has learned that the charges are likely just the opening salvo in a much larger, ongoing federal investigation into the company’s commercial email practices.

Forced Password Reset? Check Your Assumptions

August 21, 2019

Almost weekly now I hear from an indignant reader who suspects a data breach at a Web site they frequent that has just asked the reader to reset their password. Further investigation almost invariably reveals that the password reset demand was not the result of a breach but rather the site’s efforts to identify customers who are reusing passwords from other sites that have already been hacked.

But ironically, many companies taking these proactive steps soon discover that their explanation as to why they’re doing it can get misinterpreted as more evidence of lax security. This post attempts to unravel what’s going on here.

The Rise of “Bulletproof” Residential Networks

August 19, 2019

Cybercrooks increasingly are anonymizing their malicious traffic by routing it through residential broadband and wireless data connections. Most often, those connections are hacked computers, mobile phones, or home routers. But this is the story of a sprawling “bulletproof residential VPN” service that appears to have been built by acquiring chunks of Internet addresses from some the largest ISPs and mobile data providers in the United States and abroad.

Meet Bluetana, the Scourge of Pump Skimmers

August 14, 2019

“Bluetana,” a new mobile app that looks for Bluetooth-based payment card skimmers hidden inside gas pumps, is helping police and state employees more rapidly and accurately locate compromised fuel stations across the nation, a study released this week suggests. Data collected in the course of the investigation also reveals some fascinating details that may help explain why these pump skimmers are so lucrative and ubiquitous.
