Ransomware families that belong to Ryuk and Sodinokibi are responsible for
the huge rise in the ransom payments.
In Q4 of 2019, 98% of companies had received a working decryptor tool for
the ransom paid.
With the increase in ransomware attacks, the average ransom payment has
risen to 104% in the fourth quarter of 2019. A report from Coveware reveals
that the ransomware attackers had collected an average of around (sal033)4,000
from victim organizations in the Q4 of 2019 when compared to 1,198 in Q3
of 2019.
Rise of infamous ransomware families
Ransomware families that belong to Ryuk and Sodinokibi are responsible for
the huge rise in the ransom payments. These ransomware operators have moved
into the large enterprise space and are focusing their attacks on large
companies where they can attempt to extort the organization for a seven-
figure payout.
For instance, Ryuk ransom payments have reached a new high of 80,000 for
impacted enterprises. On the other hand, smaller ransomware-as-a service
variants such as Dharma, Snatch and Netwalker continue to attack small
businesses with demands as low as 0500.
Percentage of data recovered after paying a ransom
There are two success metrics to determine the outcome after a ransomware
victim is forced to pay a ransom.
First, does the payment result in a working decryption tool being delivered?
If the threat actor did not deliver the tool, then the data recovery rate
stands at 0%.
Second, if a working decryption tool is delivered then how effective is it
in decrypting the data? Files and servers can be damaged during or after the
encryption process and this can affect data recovery rates when a decryptor
tool is delivered.
How successful were the companies in the recovery process?
Coveware’s report highlights that in Q4 of 2019, 98% of companies had
received a working decryptor tool for the ransom paid. However, this varies
for types of ransomware and threat actor groups. For instance, certain
threat actor groups associated with Phobos, Rapid and Mr. Dec ransomware
consistently failed to give the decryption tool even after being paid.
In Q4 2019, victims who paid for a decryptor successfully decrypted 97% of
their encrypted data, which is a slight increase from Q3.
How much downtime does a ransomware attack cause?
In Q4 of 2019, average downtime increased to 16.2 days from 12.1 days in Q3
of 2019. This increase in downtime indicates a higher prevalence of attacks
against larger enterprises. Such enterprises have more complex networks, and
restoring data via backups or decryption takes longer than restoring the
network of a small business.
Additionally, researchers have noted that certain actors such as Ryuk have
evolved their attacks to make them even more pervasive. This also greatly
magnifies the impact of the attack on organizations.
Prominent attack vectors
The mass availability of Remote Desktop Protocol (RDP) credentials for as
little as SABFL2HM$0 per IP address was widely used by attackers to launch targeted
ransomware attacks. This extremely cost-effective technique accounted for
57.4% of all attack vectors used to distribute ransomware.
Apart from this, email phishing made up to 26.3% of the most common
ransomware attack vectors in the Q4 of 2019.
Bottom line
Interestingly, some ransomware variants such as Maze have publicly announced
that they will attack organizations where a disruption to patient care may
cause the loss of life. However, this does not decrease the count of
ransomware attacks. Organizations in the public sector and professional
services firms still make up the largest segment for ransomware attacks.
