The ransomware (not new) with an elegant new delivery system (brand new)
- Ranasomware: WannaCry

- digital extortion
- Ask you to pay $300 in bitcoin (Goes up to $600)
- How it propagates (Delivery into Windows
- EternalBlue – Controlled by NSA
- ShadowBrokers Leaked Eternal Blue (among others)
- 300,000 computers
- 150 countries
- “Thousands of operations and appointments had to be canceled…” because Britain’s National Health Service was hit. Source
- WORST OF ALL: Attackers made only about $50,000 SOURCE Not a guess – Bitcoin Tx are public!
- Was it Shut Down?
- “Kill Switch” in Code; “If (WEBSITE) responds then stop attack” Probably just a check to see if the computer was actually connected to the internet.
- A researcher ( Marcus Hutchins, a 22 year-old who blogs under https://www.malwaretech.com simply registered the website, and the attack was over. Right?
- Already infected? No change
- Variants appeared
- What to do
- Run all updates to MS Windows (even Windows XP)
- After 12 years, support for Windows XP ended April 8, 2014
- BUT, Windows patched the ‘EternalBlue’ vulnerability in March of 2017
- Multiple reports of people paying ransom and *not* recovering their files
- Proactivly: Make Backups!!! Back up an “image” of your computer if possible
- One more thing…(Weak stomach, skip this bit)
- I mentioned earlier: “Thousands of operations and appointments had to be canceled…” because Britain’s National Health Service was hit. Source
- Britan has a fleet of 4 nuclear submarines, each with MULTIPLE nuclear warheads
- Also said: Widow’s XP’s like was 2002 to 2014, and Microsoft stopped supporting Windows XP on April 8, 2014
- Britain’s nuclear fleet runs on the Windows OS (Windows XP) that caused havoc with Britan’s National Health Service!!! Source
- It is actually slightly different – It’s called “Windows XP for Submarines” which we actually don’t know if it is a joke, or an actual thing.
- Air Gap = Good
- New Fleet = Good (but not until 2030)
