You’re the victim of a Ransomware Attack

@spoole167
Somewhere is a link to a cryptocurrency wallet and an
amount you must pay.

@spoole167
How does it start?
Mostly phishing, malware, mostly targeted at Windows clients

Office Hours Monday To Saturday:
Dear Beneficiary,
Series of meetings have been held over the past 7 months with the secretary general of the
United Nations Organization. This ended 3 days ago. It is obvious that you have not received
your fund which is to the tune of $16.5million due to past corrupt Governmental Officials who
almost held the fund to themselves for their selfish reason and some individuals who have
taken advantage of your fund all in an attempt to swindle your fund which has led to so many
losses from your end and unnecessary delay in the receipt of your fund.for more information
do get back to us.
….
Upon receipt of payment the delivery officer will ensure that your package is sent within 24
working hours.

@spoole167
From <your boss>
I’ve spoken to the XYZ company CEO and they will send us the goods if we
pay $3M immediately. Details below.
I’m off to the golf course – no distractions please.

Attacks

@spoole167
Many are specifically targeted at a single company or
organisation
With personalized attacks you invest more and make it compelling.
Your victims views on Facebook about their boss, how busy they are,
important deals coming up. It all helps to craft that million dollar attack…

@spoole167
Other vectors: vulnerabilities

@spoole167
Other vectors: supply chain attacks
Hack software delivery
systems - upstream

@spoole167
The aim, as always is
Remote Code Execution

@spoole167
Once in the malware calls back home for encryption keys

@spoole167
And uses
sophisticated
techniques to
encrypt your system.
One file at a time
Least used first ..

@spoole167
While copying critical data out,
disguised as normal traffic
Sometimes hidden in other
payloads, protocols
Sometimes as responses to
‘legitimate’ requests
Almost always via botnets

@spoole167
The crime – motive
why the defendant committed the crime

@spoole167
Many motives
• Data kidnapping? - pay up or or we release the data to other bad guys
• Blackmail? - we have evidence of what you did
• Revenge? - Cripple your systems. Cause you pain
• Competitor actions? wipe you out. steal your secrets
• Something much worse? Weaponized attacks: it’s not personal, its just
practice.
Mostly money of course

@spoole167
5 years a go I said things like this
@spoole167

@spoole167
Organized Cybercrime is the most profitable type of
crime
Cybercrime was estimated to be worth 445 Billion Dollars a Year
United Nations Office on Drugs and Crime (UNODC) estimated globally the illicit
drug trade was worth 435 Billion Dollars
• Guess which one has the least risk to the criminal?
• Guess which is growing the fastest?
• Guess which one is the hardest to prosecute?
• Guess which one is predicted to reach 2100 Billion Dollars by 2019
• Guess which one is predicted to reach 6000 Billion Dollars by 2021

@spoole167
What’s the status today?

@spoole167
Ransomware alone is worth 6 Trillion Dollars

@spoole167
Overall it’s much worse than predicted …
As a developer your world is going to change rapidly
as we begin to tackle this problem
@spoole167

@spoole167
Ransomware:
It’s not all about money

@spoole167
Weaponised Cybercrime
Nation states are preparing for the next war – and
that all about software
@spoole167

@spoole167
Cyber Attacks are rising in number and sophistication
Nation states are preparing for the next war – and that all about software
The aim is to infiltrate infrastructure and essential services…

@spoole167
And manipulate or terminate

@spoole167
Ransomware can often be a visible test of an attack
methodology
plus of course, if you pay, you helped fund it

@spoole167
On that note
• Cybercrime is already almost impossible to prosecute
• Anonymous Cryptocurrencies make it almost impossible to track the
money
A big motive is – you’re don’t think your going to get caught!

@spoole167
The crime – means
the ability of the defendant to commit the crime

@spoole167
Whatever your motive..
It’s easy to buy an attack
monthly subscriptions. One-time fees, percentage of
every ransom payout
Supply chain ransomware attacks are climbing fast

@spoole167
We’re in a new
world
Are state funded
Professionally developed
Regularly exercised
Very sophisticated
And extremely lucrative

@spoole167
The crime – opportunity
whether or not the defendant had the chance to commit the crime

@spoole167
Cybercriminals used to search for vulnerabilities

Now they make their own

Ransomware is a crime
• It’s not just the money
• It’s the consequence of being out of action
• for a week, 10 days to a month
• of sending patients to other hospitals
• It’s the cost of recovery – you can expect that
you’ll need to work hard to get back to the status
Q.
• Data recovery is never 100%

@spoole167
It’s a very personal crime
• It’s the recriminations afterwards. The finger
pointing, the guilty feelings
• Ransomware makes people feel powerless,
angry. Stupid.
• Then there’s the feeling of being invaded, of
not trusting your security systems

@spoole167
Guess what – Ransomware can be a smoke screen for
something else.
• It’s not only about stealing data. it’s about
adding data in. Of secretly modifying data.
• How do you know that the data you just
paid to get back is really your data?

@spoole167
Don’t be smug.
Ransomware is everywhere
