According to Kaspersky Lab, hackers have been exploiting a vulnerability in Telegram's desktop client to mine cryptocurrencies such as Monero and ZCash. "Kaspersky said on its website that users were tricked into downloading malicious software onto their computers that used their processing power to mine currency, or serve as a backdoor for attackers to remotely control a machine," reports Bloomberg. From the report: While analyzing the servers of malicious actors, Kaspersky researchers also found archives containing a cache of Telegram data that had been stolen from victims. The Russian security firm said it "reported the vulnerability to Telegram and, at the time of publication, the zero-day flaw has not since been observed in messenger's products."

Paul Wagenseil, writing for Tom's Guide: For a monthly fee, identity-protection services promise to do whatever they can to make sure your private personal information doesn't fall into the hands of criminals. Yet many of these services -- including LifeLock, IDShield and Credit Sesame -- put personal information at risk, because they don't let customers use two-factor authentication (2FA). This simple security precaution is offered by many online services. Without 2FA, anyone who has your email address and password -- which might be obtained from a data breach or a phishing email -- could log in to the account for your identity-protection service and, depending on how the service protects them, possibly steal your bank-account, credit-card and Social Security numbers.

TechCrunch reports: Onavo Protect, the VPN client from the data-security app maker acquired by Facebook back in 2013, has now popped up in the Facebook app itself, under the banner "Protect" in the navigation menu. Clicking through on "Protect" will redirect Facebook users to the "Onavo Protect -- VPN Security" app's listing on the App Store. We're currently seeing this option on iOS only, which may indicate it's more of a test than a full rollout here in the U.S. Marketing Onavo within Facebook itself could lead to a boost in users for the VPN app, which promises to warn users of malicious websites and keep information secure as you browse. But Facebook didn't buy Onavo for its security protections. Instead, Onavo's VPN allow Facebook to monitor user activity across apps, giving Facebook a big advantage in terms of spotting new trends across the larger mobile ecosystem. For example, Facebook gets an early heads up about apps that are becoming breakout hits; it can tell which are seeing slowing user growth; it sees which apps' new features appear to be resonating with their users, and much more.
