The Truth About Viruses for macOS
There is nothing that cannot be broken
As long as computers have some kind of contact
with the outside world, and people create programs for them, there is a
possibility that some harmful software will enter your computer. Some source
code can be more secure than the other code, but there is nothing that cannot
be hacked, at least in the world of consumer software.
Macs had viruses in the past
Before the OS X, there was a certain number of
viruses that could infect Macs and do all sorts of unpleasant things with them.
However, the macOS was completely rewritten during the transition to OS X that
leads us to the fact that all these old viruses cannot infect modern Macs.
Your Mac is safe at this moment
At this particular point in time, there is no
malware that could infect your Mac. No viruses, no Trojans, no text loggers, no
botnets, nothing. You can surf the Internet, read emails, chat with instant
messaging systems until you become blue, and nothing harmful will happen to
your computer. However, there is a possibility that tomorrow morning someone
will release a virus that will take advantage of an unknown vulnerability in OS
X.
There are many malware concepts
Yes, some researchers managed to create pieces of
code that could harm Apple devices, but these things have not yet reached the real
life and open world. Additionally, many of them required some kind of
mysterious movements in order to really do some harm to your computer.
macOS definitely has errors and vulnerabilities
Most malware works by using software errors in
the operating system. And Mac has its own share of errors. Apple periodically
releases updates to the operating system. However, to date, errors in macOS have
not been a prolific enough to breed many malicious software developers.
Unix inside definitely helps
macOS uses many Unix elements, and there is a
large amount of code written by Apple for all system services and the visual
shell with which you are working all on top of Unix. This version of Unix has
been used for a long time already and has
become quite safe since many errors have
long been found and corrected over all these years.
Intel does not change the picture
Someone may worry that switching to Intel processors
can make Mac devices less secure because
malicious software for Windows is designed to use Intel processors and is
compatible with them. This is unlikely to happen
since malware is usually written using vulnerabilities in the operating system,
and not in the processor. However, this is a new approach, and it is possible
that at the given moment someone may come up with this method.
Market share does not matter
It is often claimed that there are no viruses for
Macs because they conclude only a small part of the market. To some extent,
this may be true. If you are writing
a rogue program - especially if it's part of the profit-making botnet or
spamming network - or if you want to make a name for yourself, you will most
likely target the largest share of computers. However, many developers of such
programs also like fame, after all, what is more interesting: to write another
virus for Windows or write the first super virus for Mac? Someone may want to
give a good kick to the guy.
A lot of money involved in malware creation
Most harmful programs are currently used for several
major purposes: capture information from your computer, create huge networks of
tens of thousands of computers to generate Spam and participate in DDoS attacks
on various websites, and finally, extort
money with the help of ransomware. In any case, there are huge amounts of money
circulating, and all these operations are not managed by amateurs. When there
is an economic sense to target Apple users, they will definitely be on target.
Antivirus
software for Mac devices
I'm a bit puzzled here. On the one hand, you spend
your hard earned money to buy the program to protect yourself against something
that does not really exist. However, on the other hand, you get two advantages:
a) with a suitable program you will avoid
transferring viruses to Windows users
b) when a real virus for Mac finally appears, you
will already have a ready infrastructure to repel an attack, provided that you
update the virus definitions database regularly.
