The desktop version of the security and privacy-focused, end-to-end encrypted messaging app, Telegram , has been found leaking both users' private and public IP addresses by default during voice calls. With 200 million monthly active users as of March 2018, Telegram promotes itself as an ultra-secure instant messaging service that lets its users make end-to-end encrypted chat and voice call with other users over the Internet. Security researcher Dhiraj Mishra uncovered a vulnerability (CVE-2018-17780) in the official Desktop version of Telegram (tdesktop) for Windows, Mac, and Linux, and Telegram Messenger for Windows apps that was leaking users' IP addresses by default during voice calls due to its peer-to-peer (P2P) framework. To improve voice quality, Telegram by default uses a P2P framework for establishing a direct connection between the two users while initiating a voice call, exposing the IP addresses of the two participants. Telegram Calls Could Leak Your ...

In what's likely to be a goldmine for bad actors, personal information associated with approximately 533 million Facebook users worldwide has been leaked on a popular cybercrime forum for free—which was harvested by hackers in 2019 using a Facebook vulnerability.

Security, trust, and stability — once the pillars of our digital world — are now the tools attackers turn against us. From stolen accounts to fake job offers, cybercriminals keep finding new ways to exploit both system flaws and human behavior. Each new breach proves a harsh truth: in cybersecurity, feeling safe can be far more dangerous than being alert. Here's how that false sense of security was broken again this week. ⚡ Threat of the Week Newly Patched Critical Microsoft WSUS Flaw Comes Under Attack — Microsoft released out-of-band security updates to patch a critical-severity Windows Server Update Service (WSUS) vulnerability that has since come under active exploitation in the wild.

This week showed just how fast things can go wrong when no one's watching. Some attacks were silent and sneaky. Others used tools we trust every day — like AI, VPNs, or app stores — to cause damage without setting off alarms. It's not just about hacking anymore. Criminals are building systems to make money, spy, or spread malware like it's a business. And in some cases, they're using the same apps and services that businesses rely on — flipping the script without anyone noticing at first. The scary part? Some threats weren't even bugs — just clever use of features we all take for granted. And by the time people figured it out, the damage was done. Let's look at what really happened, why it matters, and what we should all be thinking about now. ⚡ Threat of the Week Silently Patched Fortinet Flaw Comes Under Attack — A vulnerability that was patched by Fortinet in FortiWeb Web Application Firewall (WAF) has been exploited in the wild since early October 2025 by threat actors to c...
