Cryptojacking has become a lucrative choice for cybercriminals as many victims are unaware they have been compromised.
New research shows that despite falling digital asset prices, cryptojacking has reached record levels in the first half of 2022.
According to a mid-year update
on cyber threats by American cybersecurity company SonicWall, global
cryptojacking volumes rose by $66.7 million, or 30% in the first half of
2022 compared to the same period last year.
Cryptojacking is a
cybercrime whereby malicious actors commandeer a victim’s computer
resources by infecting the machine with malware designed to mine
cryptocurrencies. It is often executed through vulnerabilities in web browsers and extensions.
The report stated that the overall rise in cryptojacking can be attributed to a couple of factors.
Firstly, cybercriminals are leveraging the Log4j
vulnerability to deploy attacks in the cloud. In December 2021, a
critical vulnerability affecting java based logging utility was
discovered in the Open Source Library managed by software company
Apache. Hackers can exploit it to gain remote access to a system.
Secondly, cryptojacking is a lower-risk attack than ransomware
which needs to be made public to succeed. Cryptojacking victims are
often unaware that their computers or networks have been compromised.
Finance sector beware
Attackers
also appeared to have changed their preferred targets during the
period, moving from the government, healthcare and education sectors to
the retail and financial sectors.
Cryptojacking attacks targeting
the finance sector skyrocketed 269% in the period, more than five times
greater than the second highest industry — retail, which saw attacks
increase by 63%.
“The number of attacks on the finance industry
is five times greater than the second highest industry — retail, which
used to be at the very bottom of the list,” the researchers noted.

The
researchers, however, noted that the volume cryptojacking attacks began
to fall alongside the crypto markets in the first half of the year, as
attacks were becoming less lucrative.
They observed a pattern of
significantly higher volumes in the first quarter, followed by
“cryptojacking summer slump” in Q2. The firm said that based on past
trends, Q3 volumes will likely also be low, with attacks likely to pick
up again in Q4.
This year's summer decline has also been
attributed to a falling in crypto asset prices as markets have shrunk by
57% since the beginning of the year.
