How Cyber Criminals Target SA Firms
According to a new
security report, it looks like cyber crooks are aimed on targeting South
African companies!
The chief technology
security officer at Vodacom, Vernon Fryer, said “Hackers have identified SA
companies as ideal targets to attack for ransom.” He went on to say that in
Africa, SA is the most common target for cyber crooks, then comes Kenya, Uganda
and Algeria. Some of the top malware programs are CryptoLocker, Rombertik and
Superfish.
One of the most common
ways to attack companies in Africa is a DDOS (Distributed Denial Of Service)
attack. A DDOS attack is an attempt to make an online service unavailable by
overwhelming it with traffic from multiple sources, so the cyber criminals send
large amounts of junk data to servers which then will lead to them performing
slowly or crashing!
According to data
collected by Vernon Fryer, a typical attack on a local company sees about 4.43
terabytes of data being directed to a firm, nearly four times the amount of
data a large corporation can handle.
It was also revealed
that there has been a 150% increase in the number of DDOS attacks in the last
18 months in Africa – that is a significant increase! Not to mention the
attacks are typically very short and the criminals are shameless about their
intentions.
Here is a typical
threat message that you should look out for:
"We have not received your payment. But since our
email from which we contacted you yesterday got suspended, we are not sure if
you replied.
However, just to make sure, we will give you some more
time -until tomorrow. But if not paid until tomorrow, attack will start and
price will increase, as explained in first email.
Following such demands, criminals will usually up the
tempo of the attack to demonstrate their ability to compromise corporate
computer systems.
But if you ignore us, and don't pay within 24 hours,
long term attack will start, price to stop will go to 50 BTC and will keep
increasing for every hour of attack.
Important: It's a one-time payment. Pay and you will
not hear from us ever again! We do bad things, but we keep our word."
As seen from the above message, spam is an
ideal delivery method for malware and what follows is usually a final ransom
demand of bitcoins, which are hard to trace.
When the cyber criminals use this method of
attack they are often very successful, because corporate officers are more keen
to avoid having to report that their systems have been hacked. Paying the
ransom may seem like a viable option for some, Security Company’s advice
against it.
Always remember that these people may be
called cyber crooks, but they are still real criminals. Even if you do pay the
ransom it is not a real solution for the future.
