ESET H1 2026: ClickFix surging, AI-branded malware plugins rising, EDR killers now standard attacker toolkit.
Pattern: all designed to blind detection. None of them change what the infrastructure they run on looks like in real-time abuse telemetry.
#ThreatIntelligence #CyberSec
Phishing consumes 36.5% of security teams' time. $51,948 per analyst per year — and growing.
82% of 3.4B daily phishing emails are AI-generated. The attack cost collapsed. The defense cost didn't. #EmailSecurity #ThreatIntel
1 in 10 new domains registered in 2025 ended up on a blocklist. 8 registrars were responsible for 92% of them.
Domain aging buys time. Real-time threat intel closes the gap when they go live. #ThreatIntel #DomainAbuse
PCPJack cloud worm: 230+ hijacked servers across AWS, GCP, Azure — one persistent SMTP relay network.
Every 60 seconds the worm tests its tunnels. It's optimizing specifically to pass IP reputation checks.
Behavioral signals catch what static lists miss. #CloudSecurity #ThreatI
QR phishing up 146%. Content scanners can't read images. But the sending IPs and landing page domains still leave tracks. Network-layer reputation catches what content filters miss. #Quishing #ThreatIntel #Abusix
Median patch time: 43 days (up from 32). Vuln exploitation: now the #1 breach vector.
For ISPs: every slow-patching customer is a future abuse origin. You need to see it before the complaints arrive. #DBIR2026 #CyberSecurity #Abusix
5,500+ GitHub repos poisoned in one automated wave via hijacked Actions tokens.
Scale attacks leave infrastructure tracks. Real-time abuse data sees the wave before the reports land.
#SupplyChain #ThreatIntel
The FBI warned about Kali365 PhaaS: bypasses MFA via OAuth token theft. Content filters didn't catch it.
The sending infrastructure still left tracks. It always does.
#PhishingAsAService #ThreatIntel
cPanel CVSS 9.8 — 70M+ domains, actively exploited, CISA KEV listed.
Under NIS2, hosting providers are essential entities. "We were patching" doesn't stop compromised servers from becoming spam infrastructure.
Abuse intelligence closes that window. #NIS2 #CyberSecurity
232% more malicious domains in 6 months. AI spins up phishing infra faster than any team can track it. Your blocklist is either alive — or it's already obsolete. #ThreatIntelligence #EmailSecurity #Abusix
Glassworm botnet: infected devs via VSCode extensions, npm packages, GitHub repos. C2 infrastructure ran for months.
Attack chains change. The IPs and domains running them don't.
Real-time reputation data is still the fastest signal. #CyberSecurity #ThreatIntel
Amazon SES abused for phishing. SPF pass. DKIM pass. DMARC pass.
When attackers build their infrastructure to pass your filters by design, authentication is no longer the defense.
Behavioral signals are the layer that still works.
#EmailSecurity #Phishing #Infosec
Google. Yahoo. Microsoft. All mandated DMARC.
Result: 9% of domains at p=reject. 91% still spoofable.
Authentication without enforcement doesn't protect anything. It just creates an audit trail.
#DMARC #EmailSecurity #Infosec
Multiple critical CVEs in dnsmasq — cache poisoning, RCE, privilege escalation. Fixed in 2.92rel2.
The catch: dnsmasq is in millions of ISP-provisioned routers and embedded devices. You can't patch what you don't know you're running.
Know your stack.
#DNS #Infosec #NetworkSecu
46% of global spam now comes from compromised accounts on Gmail, Outlook, and SaaS platforms.
SPF/DKIM/DMARC all pass. IP reputation: clean. Standard defenses: blind.
What catches it: real-time abuse signals from actual receiving infrastructure.
#EmailSecurity #ThreatIntel #IS
369K devices. 163 countries. Years of operation as anonymous attack proxies. SocksEscort ran on ISP and hosting networks without detection. Real-time IP reputation finds infected devices before law enforcement does. #ISP #BotnetTakedown #Cybersecurity
Microsoft: 35K phishing victims, 13K orgs, 26 countries — in 3 days.
Sent through legitimate services. SPF/DKIM/DMARC passed clean.
QR code phishing is the fastest-growing 2026 attack vector. Static reputation can't scan behind a QR image.
