Types Of Malware

Malware (Malicious Software) is a type of software designed to harm, exploit, or disrupt computers, networks, and devices. It includes viruses, ransomware, spyware, worms, Trojans, and other threats that can steal data, damage systems, or give attackers unauthorized access.

Malware spreads through malicious emails, infected websites, USB drives, and software vulnerabilities. Effective cybersecurity measures like antivirus software, firewalls, and user awareness help protect against malware attacks.

Types of Malware
1. Ransomware – Encrypts files or locks a system, demanding payment to restore access.
2. Fileless Malware – Operates in memory without leaving traces on disk, making detection difficult.
3. Spyware – Secretly collects user data, such as passwords and browsing habits, for malicious use.
4. Adware – Displays intrusive ads, often leading to unwanted software installations or tracking user behavior.
5. Trojan – Disguises itself as legitimate software but creates backdoors for attackers.
6. Worms – Self-replicating malware that spreads across networks, consuming bandwidth and resources.
7. Rootkit – Hides deep within the system to grant attackers persistent access and control.
8. Keyloggers – Records keystrokes to steal login credentials, credit card details, and sensitive data.
9. Bots – Turns infected devices into part of a botnet for launching attacks like DDoS or spam campaigns.
10. Mobile Malware – Targets smartphones and tablets, often through malicious apps or phishing attacks.
11. Bootkit – A type of rootkit that infects the boot sector, making removal difficult.
12. Logic Bomb – Triggers malicious actions when certain conditions are met, like a specific date or user action.
13. Backdoor – Creates a hidden entry point for attackers to access a system remotely.

Malware can cause data theft, system damage, and financial loss, making cybersecurity measures essential.

🚨 End of Support for Exchange Server 2016 & 2019

Mark your calendars: On October 14, 2025, Exchange Server 2016 and 2019 will reach the end of support. After this date, Microsoft will no longer provide:
🔸 Technical support
🔸 Bug fixes
🔸 Security updates
🔸 Time zone updates

To avoid risks, I recommend migrating to Exchange Online or preparing to upgrade to Exchange Server Subscription Edition (SE), launching in early H2 2025.

Stay ahead and secure your organization’s communication infrastructure.
