E-Verify’s “SSN Lock” is Nothing of the Sort

One of the most-read advice columns on this site is a 2018 piece called “Plant Your Flag, Mark Your Territory,” which tried to impress upon readers the importance of creating accounts at websites like those at the Social Security Administration, the IRS and others before crooks do it for you. A key concept here is that these services only allow one...

Ransomware Gangs Don’t Need PR Help

We’ve seen an ugly trend recently of tech news stories and cybersecurity firms trumpeting claims of ransomware attacks on companies large and small, apparently based on little more than the say-so of the ransomware gangs themselves. Such coverage is potentially quite harmful and plays deftly into the hands of organized crime. Often the rationale behind...

COVID-19 ‘Breach Bubble’ Waiting to Pop?

The COVID-19 pandemic has made it harder for banks to trace the source of payment card data stolen from smaller, hacked online merchants. On the plus side, months of quarantine have massively decreased demand for account information that thieves buy and use to create physical counterfeit credit cards. But fraud experts say recent developments suggest...

Russian Cybercrime Boss Burkov Gets 9 Years

A well-connected Russian hacker once described as “an asset of supreme importance” to Moscow was sentenced on Friday to nine years in a U.S. prison after pleading guilty to running a site that sold stolen payment card data, and to administering a highly secretive crime forum that counted among its members some of the most elite Russian cybercrooks....

‘BlueLeaks’ Exposes Files from Hundreds of Police Departments

Hundreds of thousands of potentially sensitive files from police departments across the United States were leaked online last week. The collection, dubbed “BlueLeaks” and made searchable online, stems from a security breach at a Texas web design and hosting company that maintains a number of state law enforcement data-sharing portals. The collection...

Turn on MFA Before Crooks Do It For You

Hundreds of popular websites now offer some form of multi-factor authentication (MFA), which can help users safeguard access to accounts when their password is breached or stolen. But people who don’t take advantage of these added safeguards may find it far more difficult to regain access when their account gets hacked, because increasingly thieves...

FEMA IT Specialist Charged in ID Theft, Tax Refund Fraud Conspiracy

An information technology specialist at the Federal Emergency Management Agency (FEMA) was arrested this week on suspicion of hacking into the human resource databases of University of Pittsburgh Medical Center (UPMC) in 2014, stealing personal data on more than 65,000 UPMC employees, and selling the data on the dark web. On June 16, authorities in...

When Security Takes a Backseat to Productivity

“We must care as much about securing our systems as we care about running them if we are to make the necessary revolutionary change.” -CIA’s Wikileaks Task Force. So ends a key section of a report the U.S. Central Intelligence Agency produced in the wake of a mammoth data breach in 2016 that led to Wikileaks publishing thousands of classified documents...

Privnotes.com Is Phishing Bitcoin from Users of Private Messaging Service Privnote.com
