Background for this topic.
Cryptocurrency is a digital asset secured by cryptography and recorded on a decentralized blockchain ledger. It enables peer-to-peer transactions without intermediaries, relying on consensus mechanisms like proof-of-work or proof-of-stake to validate and add transaction blocks. Users control funds through private keys, which are critical for accessing and transferring cryptocurrency.
From an information security perspective, protecting private keys is paramount, as their compromise leads to irreversible theft. Cryptocurrency exchanges and wallet software are frequent targets for hacking, requiring robust security controls and vulnerability management. Additionally, the pseudonymous nature of transactions can facilitate illicit activities, challenging efforts to trace funds and enforce compliance. Defenses include hardware wallets, multi-factor authentication, and secure key management practices to mitigate risks inherent in cryptocurrency operations.

We tracked a cryptocurrency-mining campaign exploiting CVE-2026-33017, which revealed how threat actors are now scanning exposed AI application infrastructure for their next foothold.
In this blog entry, we discuss how an attacker took advantage of the Atlassian Confluence vulnerability CVE-2023-22527 to connect servers to the Titan Network for cryptomining purposes.
A technical analysis on how CVE-2023-22527 can be exploited by malicious actors for cryptojacking attacks that can spread across the victim’s system
Water Sigbin (aka the 8220 Gang) exploited the Oracle WebLogic vulnerabilities CVE-2017-3506 and CVE-2023-21839 to deploy a cryptocurrency miner using a PowerShell script. The threat actor also adopted new techniques to conceal its activities, making attacks harder to defend against.
We uncovered the active exploitation of the Apache ActiveMQ vulnerability CVE-2023-46604 to download and infect Linux systems with the Kinsing malware (also known as h2miner) and cryptocurrency miner.
Users are advised to patch immediately: We found exploit samples abusing the Atlassian Confluence vulnerability (CVE-2022-26134) in the wild for malicious cryptocurrency mining.
Recently, we observed the Spring4Shell vulnerability — a remote code execution bug, assigned as CVE-2022-22965 — being actively exploited by malicious actors to deploy cryptocurrency miners.
