Imagine sending a sealed letter across a crowded city where anyone might intercept it. The seal on the envelope keeps the contents private, the signature on the letter proves the sender is who they claim to be, and reusing the same secure channel later without starting from scratch keeps things efficient. That’s roughly how the internet’s main security protocol works every time you open a banking site, send a message, or load an app. The protocol, known as Transport Layer Security (TLS), creates

Researchers have been tracking a previously undocumented Linux botnet family, which we have named Evooo1Bot. The name derives from the hardcoded string “evooo1” found in every binary. While the malware reuses the DDoS engine from the publicly leaked Mirai source code, it extends the original framework with numerous capabilities, including encrypted C2 communications, an SSH brute-force scanner, a SOCKS relay module, a credential sniffer, and an integrated exploit arsenal targeting multiple kno
The National Cyber Security Center (NCSC), alongside the FBI, NSA, and sixteen other international partners, has issued a joint advisory for critical national infrastructure (CNI) sectors. The guidance urges organizations to improve defenses against Russian intelligence services, specifically FSB Center 16. This actor is actively scanning for vulnerable routers, exploiting well-known Cisco device flaws, weak SNMP passwords, and legacy protocols.[1]

Throughout early 2026, SentinelOne’s® Digital Forensics & Incident Response (DFIR) team has responded to several incidents in which FortiGate Next-Generation Firewalls (NGFW) have been compromised to establish a foothold in the targeted environment. Each incident was detected and stopped during the lateral movement phase of the attack. Fortinet disclosed and issued patches for several high-severity vulnerabilities, allowing unauthorized access during our investigation period. Successful explo
Remote Access Trojans, also known as RATs, have been around for years, although their prevalence in the market has surged recently. RATs are digital skeleton keys, giving an attacker remote control over a system, often without the user ever knowing. This kind of access often starts with someone clicking a malicious link or opening a rogue attachment in a phishing email or messaging app. From there, the attacker can move laterally, steal data, monitor activity, or trigger ransomware.
RATs have
