IBM researchers have found that cryptojacking dominated the cryptocurrency cybercrime scene in 2018, overtaking ransomware attacks. Experts say the comparatively less intrusive and stealthy nature of malicious crypto-mining is the primary reason why it is fast becoming the attack vector of choice for cybercriminals.
Cybercriminals Pivot to Cryptojacking
In a report published by the IBM X-Force Research team on Wednesday (February 27, 2019), the company reported that 2018 saw a massive increase in cyber attacks against organizations across the world.
According to the report, cryptojacking dominated the field as cybercriminals appear to be pivoting away from ransomware and malware attacks.
The report indicated that stealthy cryptocurrency mining attacks increased by 450 percent between Q1 and Q4 2018. Meanwhile, ransomware attacks dropped by 45 percent during the same period. IBM says the extent of the spread of cryptojacking attacks covers both desktop and mobile platforms.
Cryptojacking is Less Disruptive
Experts say cybercriminals are pivoting towards malicious crypto-mining due to its less disruptive nature. Speaking to Fortune, Charles Henderson of the IBM X-Force Red, said:
With the extortion racket of ransomware, you lose the customer after one transaction, so it’s a one and done, there’s no recurring revenue-I mean it’s just bad business.
According to Henderson, cryptojacking is akin to a revenue subscription model where the hacking cartels can count on a continuous revenue stream as long as the victims remain unaware. Whereas, for ransomware attacks, the attacker only gets one bulk payment per victim.
More Sinister Repercussions Up Ahead
While malicious crypto-mining might appear less menacing on the surface than ransomware and malware attacks, Henderson says ignoring its spread could have severe repercussions in the future. He adds that it is not beyond the realms of possibility for criminals to use cryptojacking for more malicious attack vectors.
What’s more, experts like Henderson say cybercriminals are perfecting their craft. Thus, if left unchecked, cryptojacking can move from surreptitious virtual currency mining to botnets used for spyware attacks. As always, readers are advised to run the latest antivirus software version and avoid installing programs from unofficial sources.
