Riccardo Padovani: Responsible disclosure: improper access control in Gitlab private project.
As I said back in September with regard to a responsible disclosure about Facebook, data access control isn’t easy. While it can sound quite simple (just give access to the authorized entities), it is very difficult, both on a theoretical side (who is an authorized entity? What does authorized mean? And how do we identify an entity?) and on a practical side.

Integrating Password and Privilege Management for Unix and Linux Systems[Ed: More spammy pages under the guise of "whitepaper"]
Unix and Linux build the foundation for most business-critical systems. Thus, they present target-rich environments for cyber-attackers. Privileged Access Management (PAM) helps to mitigate such risks. To succeed, security teams must follow an integrated approach, covering both privilege elevation and centralized management of shared account credentials.

How Not to Acknowledge a Data Breach
My guess is that what Wipro means by “zero-day” is a malicious email attachment that went undetected by all commercial antivirus tools before it infected Wipro employee systems with malware.

Facebook stored millions of Instagram passwords in plain text
Facebook says it stored millions of Instagram users’ passwords in plain text, leaving them exposed to people with access to certain internal systems. The security lapse was first reported last month, but at the time, Facebook said it only happened to “tens of thousands of Instagram users,” whereas the number is now being revised up to “millions.” The issue also affected “hundreds of millions of Facebook Lite users” and “tens of millions of other Facebook users.”

Update: Facebook passwords for hundreds of millions of users were exposed to Facebook employees
Facebook confirmed March 21 that hundreds of millions of user passwords were being stored in a “readable format” within its servers, accessible to internal Facebook employees—including millions more Instagram users than previously thought. Affected users will be notified, Facebook said, so they can change those passwords.

Facebook 'unintentionally' uploaded 1.5 million people's email contacts without asking
This is how it unfolded: a security researcher spotted that Facebook was asking some users to put in their email passwords when they signed up with a new account to verify their identity. Business Insider then experimented with what would happen if you were brave/mad enough to do so and found that a message popped up saying it was "importing" its contacts without having the decency to check that was okay first.
Apparently, 1.5 million people just accepted this as just one of those things, and the information was then used to build up Facebook's uncanny ability to predict when you know somebody.

Facebook's privacy gaffes keep coming. On Wednesday, the social media company said it collected the stored email address lists of as many as 1.5 million users without permission. On Thursday, the company said the number of Instagram users affected by a previously reported password storage error was in the "millions," not the "tens of thousands" as previously estimated.

With Nation Distracted by Mueller Report, Facebook Admits Millions of Users' Passwords Affected by Latest Privacy Breach
On Thursday, Facebook added to a blog post from March 21 to let users know that instead of storing tens of thousands of Instagram passwords, as it had reported last month, the number of users affected by the privacy breach was in the millions. Facebook is the parent company of Instagram.
"Since this post was published, we discovered additional logs of Instagram passwords being stored in a readable format," wrote Pedro Canahuati, vice president of Engineering, Security and Privacy. "We now estimate that this issue impacted millions of Instagram users. We will be notifying these users as we did the others."
The stored passwords were found in January during a routine security check, according to Facebook. In March, when the breach was first announced, the company said the passwords were never visible to anyone outside of Facebook.
