1. Preventing Malware

2. RAT is similar to Backdoors

1. Update your anti-malware SW automatically and scan your computer. 2 Update and patch the OS and applications regularly. 3. SATE for users on safe internet surfing practices.Allow attacker access to your system.Method of bypassing normal security and authentication functions. Initially done in the 80s to do repairs/SW updates...without user permissions, not designed to be bad, but others can use them and be malicious. Bad PRACTICE in current networks. Today it is considered a breach of good business practices. A malicious attack that is directed toward a smaller group of specific individuals by embedding malware in a website frequented by these individuals (FB is common, a watering hole). Supplier you have for your business you visit...then infect it, then it can go to all their clients, ex get an invoice. Luckily, most sites like Google, FB are well protected. But they might use type squatting i.e. use a site with similar name to fool you.

3. Watering Hole Attack

5. Symptoms of Malware Infections

1. Update your anti-malware SW automatically and scan your computer. 2 Update and patch the OS and applications regularly. 3. SATE for users on safe internet surfing practices.Allow attacker access to your system.Your PC might begins to act strange. Running slower (worm, botnet, Spam) is most common. PC starts locking up or stopping frequently. Restarts or crashes a lot, another symptom. HD, Files, apps not accessible. Infection may have taken over permission and now you are locked out. Strange noises, unusual error message, jumbled printouts (symbols vs. text). New icons on desktop or they disappear. Double file extensions textfile.txt.exe the .exe would indicate the issue i.e. executable file that can imbed malware further. Try running AV and it does not run. A lot of malware attacks AV and allows malware to last longer and did in deeper. Files or folders are corrupted/missing/created. Final System, restore will not function. Malware will turn this off to keep a good backup from being restored thereby taking the malware off the system. Summary, if your PC is acting strange or you observe changes, probably infected.

7. Ransomware is generally detected by its delivery method which is often

A Trojan Horse. If you can catch that, you should be able to stop the ransomware. There is anti-spyware, adware...MS Defender has these. Root virus, best to reimage from a good restore...1. Update your anti-malware SW automatically and scan your computer. 2 Update and patch the OS and applications regularly. 3. SATE for users on safe internet surfing practices.A malicious attack that is directed toward a smaller group of specific individuals by embedding malware in a website frequented by these individuals (FB is common, a watering hole).

But they might use type squatting i.e. use a site with similar name to fool you.Allow attacker access to your system.

8. DDoS (Distributed Denial of Service)

1. Update your anti-malware SW automatically and scan your computer. 2 Update and patch the OS and applications regularly. 3. SATE for users on safe internet surfing practices.An attack on a computer or network - device in which multiple computers send data and requests to the device in an attempt - to overwhelm it so that it cannot perform normal operations. Make money is primary use, crypto mining by using victims machines for processing power by the 1000s, used for breaking encryption. Should notice processing power slower on your PCA malicious attack that is directed toward a smaller group of specific individuals by embedding malware in a website frequented by these individuals (FB is common, a watering hole). Supplier you have for your business you visit...then infect it, then it can go to all their clients, ex get an invoice. Luckily, most sites like Google, FB are well protected. But they might use type squatting i.e. use a site with similar name to fool you.Allow attacker access to your system.

SATE for users on safe internet surfing practices.First, scan and identify symptoms of malware infection. 2nd quarantine the infected system (if in a network). Turn off network card or unplug network cable/wifi. 3rd disable system restore (if windows) so you are not continuing to take snapshots of an infected machine and delete those during time of infection. 4th remediate the infected system. Updating AV, Anti-malware, scanning / quarantine capabilities...By booting in safe mode and going into a pre-installation environment then running the scans. 5th Schedule automatic updates and scans. This will ensure you removed malware and prevent it from coming back. 6th enable system restore and create a new restore point and label as a known good backup. 7th Provide user SATE, important, if they know, they should not introduce malware.
