It is amazing that this sort of thing can still happen:
…the list was compiled by scanning the entire internet for devices that were exposing their Telnet port. The hacker then tried using (1) factory-set default usernames and passwords, or (2) custom, but easy-to-guess password combinations.
Telnet? Default passwords? In 2020?
We have a long way to go to secure the IoT.
EDITED TO ADD (7/14): Apologies, but I previously blogged this story in January.

iOS apps are repeatedly reading clipboard data, which can include all sorts of sensitive information.
While Haj Bakry and Mysk published their research in March, the invasive apps made headlines again this week with the developer beta release of iOS 14. A novel feature Apple added provides a banner warning every time an app reads clipboard contents. As large numbers of people began testing the beta release, they quickly came to appreciate just how many apps engage in the practice and just how often they do it.
This YouTube video, which has racked up more than 87,000 views since it was posted on Tuesday, shows a small sample of the apps triggering the new warning.
EDITED TO ADD (7/6): LinkedIn and Reddit are doing this.

Used Tesla components, sold on eBay, still contain personal information, even after a factory reset.
This is a decades-old problem. It’s a problem with used hard drives. It’s a problem with used photocopiers and printers. It will be a problem with IoT devices. It’ll be a problem with everything, until we decide that data deletion is a priority.

Originally, ransomware didn’t involve any data theft. Malware would encrypt the data on your computer, and demand a ransom for the encryption key. Now ransomware is increasingly involving both encryption and exfiltration. Brian Krebs wrote about this in December. It’s a further incentive for the victims to pay.
Recently, the aerospace company Visser Precision was hit by the DoppelPaymer ransomware. The company refused to pay, so the criminals leaked documents and data belonging to Visser Precision, Lockheed Martin, Boeing, SpaceX, the US Navy, and others.

This is a big deal:
Whisper, the secret-sharing app that called itself the “safest place on the Internet,” left years of users’ most intimate confessions exposed on the Web tied to their age, location and other details, raising alarm among cybersecurity researchers that users could have been unmasked or blackmailed.
The records were viewable on a non-password-protected database open to the public Web. A Post reporter was able to freely browse and search through the records, many of which involved children: A search of users who had listed their age as 15 returned 1.3 million results.
The exposed records did not include real names but did include a user’s stated age, ethnicity, gender, hometown, nickname and any membership in groups, many of which are devoted to sexual confessions and discussion of sexual orientation and desires.
The data also included the location coordinates of the users’ last submitted post, many of which pointed back to specific schools, workplaces and residential neighborhoods.
Or homes. I hope people didn’t confess things from their bedrooms.

Krebs on Security is reporting a massive data leak by the real estate title insurance company First American Financial Corp.
“The title insurance agency collects all kinds of documents from both the buyer and seller, including Social Security numbers, drivers licenses, account statements, and even internal corporate documents if you’re a small business. You give them all kinds of private information and you expect that to stay private.”
Shoval shared a document link he’d been given by First American from a recent transaction, which referenced a record number that was nine digits long and dated April 2019. Modifying the document number in his link by numbers in either direction yielded other peoples’ records before or after the same date and time, indicating the document numbers may have been issued sequentially.
The earliest document number available on the site — 000000075 — referenced a real estate transaction from 2003. From there, the dates on the documents get closer to real time with each forward increment in the record number.
This is not an uncommon vulnerability: documents without security, just “protected” by a unique serial number that ends up being easily guessable.
Krebs has no evidence that anyone harvested all this data, but that’s not the point. The company said this in a statement: “At First American, security, privacy and confidentiality are of the highest priority and we are committed to protecting our customers’ information.” That’s obviously not true; security and privacy are probably pretty low priorities for the company. This is basic stuff, and companies like First America Corp. should be held liable for their poor security practices.

A recent experiment found all sorts of personal data left on used laptops and smartphones.
This should come as no surprise. Simson Garfinkel performed the same experiment in 2003, with similar results.
