Emergence of Cryptojacking Threats
In the ever-evolving landscape of cybersecurity, cryptojacking has emerged as a formidable challenge.

This stealthy technique involves unauthorized installation and operation of cryptocurrency mining software, effectively hijacking users’ computational power for profit.

The report introduced a couple of notorious malware families, notably PsMiner and CookieMiner. PsMiner, which specifically targets Windows users, operates by deploying its payload through a PowerShell command. This method has swiftly become the go-to technique for cryptojackers targeting Windows platforms.
On the flip side, Apple users are not off the hook. Enter CookieMiner, a sophisticated strain that not only mines Koto cryptocurrency but also creeps into user data — primarily from leading crypto exchanges such as Binance and Coinbase. Talk about a double whammy!

In addition to cryptojacking woes, McAfee’s report highlighted a staggering 118% rise in ransomware incidents in the same period. A significant player in this realm is the Ryuk malware family, which caused disruptions so severe that it halted newspaper printing across the United States. Now that’s some serious cyber mischief!
A Cybercrime Operation, Not a State Power Move
Interestingly, McAfee Labs pointed out that Ryuk seems to operate independently from nation-states. Its patterns align more closely with organized cybercriminal activities rather than state-sponsored operations. Think of it as a digital
