A new type of ransomware that attacks OS X
gadgets has been identified by specialists. The ransomware, known as
KeRanger, was found on a genuine site of the open-source torrent client
Transmission, as the experts said in their short article published this
weekend.
Ransomware represents a controversial
type of viruses that is rising. Often distributed via phishing
strategies and harmful information, ransomware aims to infect affected
or insecure devices in order to encrypt data and keep people out of the
PC and network.
As outlined by the latest case of several
German medical centers affected by ransomware, after the systems are
closed, this type of viruses creates a new page and requires a ransom in
Bitcoin, the virtual currency
People then usually have just two
options: to recover their information from a prior back up or to pay
this ransom. However, for some older editions of ransomware, such as
CryptoLocker, cyber security professionals have launched free saving
packages to eliminate attacks.
OS X-enabled ransomware is much rarer
than MS Windows editions. The other identified type ransomware affecting
Macs is FileCoder, found in 2014. This virus was discovered within a
couple Transmission setup as harmful .dmg data on the formal web page.
The experts do not understand how the
harmful versions crawl their way into the web page, but the open-source
application was recompiled or changed after the page was affected by the
hacker. Named KeRanger, this ransomware was marked with a legitimate
Mac database certification, which permitted it to avoid Apple’s tight
Gatekeeper protection barriers.
Once downloadable, the ransomware
releases an exe computer file inside the device and then stays for 3
days before linking to the attacker’s control server through the Tor
system. The viruses then start to spread and encrypt files, locking the
network and requiring a ransom in Bitcoins calculated at around $400.
The specialists say that it is probable
the ransomware may still be in its development phase. There are signs
within the code that suggest extra features under testing. These were
not finished or applied, such as the initiatives to make backdoor
options and secure information saved inside the Apple Time Machine
service.
If this back-up information is locked,
users will not be capable to restore their affected data using the Time
Machine, according to experts. After the scientists informed Apple about
these new results, the iPhone and iPad manufacturer suspended the
certification that allows the harmful computer file to be to downloaded.
Now, customers are alerted if they want
to download or open the fake .dmg data. Furthermore, Google has modified
its XProtect signatures in order to cover this ransomware family.
Starting last week, Transmission eliminated the harmful information from
its web page, and content will now be secure for viewing and
downloading.
If people got the installation software
from the legit open-source venture’s web page after March 5, then they
will have to scan it against contamination with KeRanger. In addition,
is it recommended to perform a system scan downloads from other sites,
too.
