Elyse Betters Picaro / ZDNETHigh-profile officials, including national security adviser Mike Waltz, have inadvertently exposed their networks through public Venmo accounts, according to WIRED. This serves as an important reminder for all Venmo users to review their privacy settings.Also: Did you get paid through Venmo, CashApp, or PayPal in 2024? The IRS will knowIf you haven’t checked your Venmo settings, your entire friends list and transaction history may be visible to the public. While it might seem harmless if someone sees that you sent a friend $10 for a shared pizza last month, your account could be revealing far more sensitive information than you realize. What people can see on Venmo By default, Venmo makes every payment and description public. The amount is hidden, but just by browsing through a few random friends’ accounts, I was able to see the location of their kids’ sports leagues, the name of a wedding venue for an upcoming ceremony, the name of a child’s classmate at elementary school, and even restaurants they frequent.Also: This new tool lets you see how much of your data is exposed online – and it’s freeJust as concerning is that your friends list is also public by default. Looking at my friends’ contact lists, it wasn’t hard to find their family members, coworkers, children’s teachers, daycare workers, and more. This information could be exploited by anyone — online trolls, stalkers, ex-spouses, law enforcement (in 2019, federal prosecutors used Venmo transactions as evidence in the case against a man involved in rapper Mac Miller’s death), or criminals.A few years ago, BuzzFeed was able to find former President Joe Biden’s Venmo account. The issue wasn’t that the public could see he sent money to his grandchildren for their birthdays, but that it exposed an entire web of contacts, including family members and senior White House officials (and their networks).Also: The best data removal services: Delete yourself from the internetNow, WIRED has reported that the US’s national security adviser, along with other senior officials, left their Venmo accounts public, exposing their extensive network of personal and professional connections. Waltz’s account, for instance, displayed a list of 328 people, including figures like White House chief of staff Susie Wiles and several prominent media figures. This kind of exposure could be exploited by foreign intelligence services, posing a potential national security risk.While researching for this article, I found several public profiles for local politicians, athletes from pro sports teams in my area, heads of local law enforcement organizations, local TV reporters, and more. By looking at each of their profiles, I got a clear picture of the people they interact with and the places they visit. More

I couldn’t ignore this suspicion, but they offered to pay me rates I’d never been paid before.  I accepted the gig, knowing I’d have to take extra precautions to keep my information safe.

ZDNETMessaging app Signal is in the news, and not for anything positive. Defense Secretary and former Fox News contributor Pete Hegseth recently demonstrated how not to use a secure communications channel to share sensitive and classified information. A reporter for The Atlantic found himself inadvertently included in a text conversation among senior administration officials discussing plans for military strikes in Yemen. The situation is a major problem for a few key reasons, as described by BBC News. Also: WhatsApp vs. Signal vs. Telegram vs. Facebook: What data do they have about you?However, Signal itself is not to blame. Rather, the onus falls on the government officials who failed to take the proper precautions. In the right hands, Signal can be an effective tool for keeping your chats private and secure. So, what is Signal, and why might you opt to use it instead of another messaging app? Here are seven reasons. 1. End-to-end encryption By default, Signal secures your texts (and your phone calls) with advanced end-to-end encryption. This means that no one, including the Signal Foundation, can read your messages or listen to your calls. For this, Signal uses its own built-in open-source encryption protocol. Not all messaging apps and formats encrypt your texts by default. And when compared with the ones that do, Signal’s protocol is still considered among the best.2. No ads or trackers With Signal, you won’t see any ads or marketing messages, and you won’t be tracked. The Signal Foundation is a non-profit organization focused on privacy and security. This contrasts with other messaging apps such as Facebook Messenger, iMessage, and even WhatsApp, all of which can collect certain metadata about your texts. More

In recent months, the American public has been hit with waves of texts claiming they owe unpaid tolls or E-ZPass bills.

23andMe/ZDNETI was an early 23andMe user. While I knew a good deal about my family history — primarily Scottish-Irish who came to the US in the aftermath of the 1845-52 Irish potato famine — I wanted to know more. At first, 23andMe was useful, but now it’s another story. Once a genetic testing trailblazer, 23andMe has filed for Chapter 11 bankruptcy. This came after years of financial instability, operational missteps, and growing concerns over customer data privacy. The company’s collapse raises serious questions about the future of its vast troves of genetic data collected from more than 15 million customers, including my own records. We have no idea what will become of our records — and that’s not a comfortable feeling. Also: The best secure browsers for privacy: Expert testedFounded nearly two decades ago, 23andMe gained popularity by offering at-home DNA testing kits that provided insights into ancestry, genetic traits, and potential health risks. At its peak in 2021, the company’s market valuation exceeded $6 billion. However, in recent years, it’s been declining rapidly. The company’s attempted pivot into pharmaceutical research and drug development partnerships, including a high-profile collaboration with GlaxoSmithKline (GSK), never met expectations. This, in turn, led to declines in revenue,The company’s reputation also never recovered from the hit it took when a major data breach in October 2023 exposed user data for about half its users. The result? The company value, which hovered above $6 billion in 2021 after its IPO, was trading for less than $50 million last week before the bankruptcy filing with losses in its current fiscal year of $174 million.

However, Cloudflare may have found a use case where artificial intelligence could help protect original content from the tentacles of AI companies.  On Wednesday, the company […] More
