Critical Flaws in PGP and S/MIME Tools Can Reveal Encrypted Emails in Plaintext

May 14, 2018
Note— the technical details of the vulnerabilities introduced in this article has now been released, so you should also read our latest article to learn how the eFail attack works and what users can do to prevent themselves. An important warning for people using widely used email encryption tools—PGP and S/MIME—for sensitive communication. A team of European security researchers has released a warning about a set of critical vulnerabilities discovered in PGP and S/Mime encryption tools that could reveal your encrypted emails in plaintext. What's worse? The vulnerabilities also impact encrypted emails you sent in the past. PGP, or Pretty Good Privacy, is an open source end-to-end encryption standard used to encrypt emails in a way that no one, not even the company, government, or cyber criminals, can spy on your communication. S/MIME, Secure/Multipurpose Internet Mail Extensions, is an asymmetric cryptography-based technology that allows users to send digitally signed ...

Aug 25, 2025 Cybersecurity News / Hacking
Cybersecurity today moves at the pace of global politics. A single breach can ripple across supply chains, turn a software flaw into leverage, or shift who holds the upper hand. For leaders, this means defense isn't just a matter of firewalls and patches—it's about strategy. The strongest organizations aren't the ones with the most tools, but the ones that see how cyber risks connect to business, trust, and power. This week's stories highlight how technical gaps become real-world pressure points—and why security decisions now matter far beyond IT. ⚡ Threat of the Week Popular Password Managers Affected by Clickjacking — Popular password manager plugins for web browsers have been found susceptible to clickjacking security vulnerabilities that could be exploited to steal account credentials, two-factor authentication (2FA) codes, and credit card details under certain conditions. The technique has been dubbed Document Object Model (DOM)-based extension clickjacking by independent sec...

Power doesn't just disappear in one big breach. It slips away in the small stuff—a patch that's missed, a setting that's wrong, a system no one is watching. Security usually doesn't fail all at once; it breaks slowly, then suddenly. Staying safe isn't about knowing everything—it's about acting fast and clear before problems pile up. Clarity keeps control. Hesitation creates risk. Here are this week's signals—each one pointing to where action matters most. ⚡ Threat of the Week Ghost Tap NFC-Based Mobile Fraud Takes Off — A new Android trojan called PhantomCard has become the latest malware to abuse near-field communication (NFC) to conduct relay attacks for facilitating fraudulent transactions in attacks targeting banking customers in Brazil. In these attacks, users who end up installing the malicious apps are instructed to place their credit/debit card on the back of the phone to begin the verification process, only for the card data to be sent to an attacker-controlled NFC relay...
Update Windows 10 Immediately to Patch a Flaw Discovered by the NSA

Update Windows 10 Immediately to Patch a Flaw Discovered by the NSA

Jan 14, 2020
After Adobe today releases its first Patch Tuesday updates for 2020, Microsoft has now also published its January security advisories warning billions of users of 49 new vulnerabilities in its various products. What's so special about the latest Patch Tuesday is that one of the updates fixes a serious flaw in the core cryptographic component of widely used Windows 10, Server 2016 and 2019 editions that was discovered and reported to the company by the National Security Agency (NSA) of the United States. What's more interesting is that this is the first security flaw in Windows OS that the NSA reported responsibly to Microsoft, unlike the  Eternalblue SMB flaw that the agency kept secret for at least five years and then was leaked to the public by a mysterious group, which caused WannaCry menace in 2017. CVE-2020-0601: Windows CryptoAPI Spoofing Vulnerability According to an advisory released by Microsoft, the flaw, dubbed ' NSACrypt ' and tracked as CVE-20...

Jul 21, 2025 Enterprise Security / Zero Day
Even in well-secured environments, attackers are getting in—not with flashy exploits, but by quietly taking advantage of weak settings, outdated encryption, and trusted tools left unprotected. These attacks don't depend on zero-days. They work by staying unnoticed—slipping through the cracks in what we monitor and what we assume is safe. What once looked suspicious now blends in, thanks to modular techniques and automation that copy normal behavior. The real concern? Control isn't just being challenged—it's being quietly taken. This week's updates highlight how default settings, blurred trust boundaries, and exposed infrastructure are turning everyday systems into entry points. ⚡ Threat of the Week Critical SharePoint Zero-Day Actively Exploited (Patch Released Today) — Microsoft has released fixes to address two security flaws in SharePoint Server that have come under active exploitation in the wild to breach dozens of organizations across the world.

Everything feels secure—until one small thing slips through. Even strong systems can break if a simple check is missed or a trusted tool is misused. Most threats don't start with alarms—they sneak in through the little things we overlook. A tiny bug, a reused password, a quiet connection—that's all it takes. Staying safe isn't just about reacting fast. It's about catching these early signs before they blow up into real problems. That's why this week's updates matter. From stealthy tactics to unexpected entry points, the stories ahead reveal how quickly risk can spread—and what smart teams are doing to stay ahead. Dive in. ⚡ Threat of the Week U.S. Disrupts N.

Sep 01, 2025 Cybersecurity News / Hacking
Cybersecurity today is less about single attacks and more about chains of small weaknesses that connect into big risks. One overlooked update, one misused account, or one hidden tool in the wrong hands can be enough to open the door. The news this week shows how attackers are mixing methods—combining stolen access, unpatched software, and clever tricks to move from small entry points to large consequences.  For defenders, the lesson is clear: the real danger often comes not from one major flaw, but from how different small flaws interact together. ⚡ Threat of the Week WhatsApp Patches Actively Exploited Flaw — WhatsApp addressed a security vulnerability in its messaging apps for Apple iOS and macOS that it said may have been exploited in the wild in conjunction with a recently disclosed Apple flaw in targeted zero-day attacks.
