Passkeys eliminate many password-based attacks, but researchers have documented 39 methods for compromising authentication built around them. Token explains how attackers can abuse authentication prompts, synced credentials, enrollment, recovery, and other trust boundaries without breaking FIDO2 cryptography. [...]

Infostealers can expose far more than passwords, including authenticated sessions that may let attackers bypass MFA. Flare explains how defenders can prioritize compromised identities, determine whether stolen access is still usable, and respond before it leads to account takeover. [...]

Ransomware resilience requires more than backups or endpoint detection alone. Acronis outlines six capabilities MSPs should test across client environments, from reducing exposure and detecting attacks to preserving recovery points and restoring operations quickly. [...]

Attackers can hide behind residential proxies, VPNs, and other infrastructure that makes malicious sessions appear legitimate to existing edge security controls. Spur explains how session enrichment adds data points that help organizations identify risky sessions and make stronger enforcement decisions. [...]

File servers remain a critical part of many IT environments, but managing access securely can become complex as permissions accumulate. tenfold Software outlines five best practices for simplifying file server administration and maintaining least-privilege access. [...]

AI is accelerating vulnerability discovery, putting pressure on systems built to enrich, prioritize, and remediate flaws at a slower pace. Action1 explains why defenders increasingly need to correlate multiple intelligence sources and turn vulnerability data into faster remediation. [...]

Threat research gives security teams insight into how attackers operate, while MDR turns that intelligence into faster detection and response. ESET explains how combining threat intelligence, continuous monitoring, and human expertise can help SMBs strengthen their defenses. [...]

Snowflake is ending password authentication for legacy service accounts, forcing organizations to migrate them to passwordless methods. Token Security explains why the harder challenge is identifying what uses each account, who owns it, and how much access it still needs. [...]

Attackers are increasingly targeting the processes used to establish or recover identity rather than attacking the login itself. Specops explains how stronger identity verification can help organizations prevent fake workers and social engineering attacks from gaining legitimate access. [...]

Public TLS validity dropped from 398 days to 200 days on March 15, 2026, the first of three cuts on the way to 47 days in March 2029. Most CAs moved early, so certificates issued from late February onward begin expiring in September and through October.

A breach at South Korea's government-backed startup platform exposed encrypted personal data after an encryption key was included in an API. Penta Security explains why encryption keys must be securely managed and kept separate from the data they protect. [...]

Windows named pipes provide fast interprocess communication, but weak access controls can expose privileged services to untrusted processes. ThreatLocker explains how endpoint verification, command authorization, strict input validation, and narrowly scoped privileges can help secure named-pipe communication. [...]

Using the same email, phone number, payment method, and other identifiers makes it easier for data brokers and attackers to profile your activity. Anonyome Labs explains how separate digital personas can reduce correlation and limit the impact of breaches, spam, and identity theft. [...]

AI is making phishing attacks more personalized, convincing, and difficult for traditional email filters to detect. Kaseya explains how MSPs can monitor identity, email, and endpoint activity to detect and contain attacks that make it past the inbox. [...]

Huntress observed a 155x increase in password spraying attacks in H1 2026, including a campaign that generated more than 81 million login attempts in two weeks. The attacks exploited legacy authentication and gaps in MFA policies that left some login flows unprotected. [...]

AI can help you patch faster. It can also help you make the wrong call faster.

Security controls can block a familiar attack method while missing quieter ways to achieve the same objective. Picus Security's Blue Report 2026 shows how prevention rates can vary dramatically by technique and why behavioral testing is needed to uncover those gaps. [...]

CVE-2026-54121 lets a standard domain user turn your Enterprise CA into a Domain Controller. The patch is the easy part. The lesson is standing privilege, implicit trust, and treating PKI as the Tier 0 identity infrastructure it has always been. [...]
