Cryptomining malware is now by far the most common event we are seeing attacking our user base and this is only the beginning. small bitcoin transactions with weak‘ brainwallet’ produced keys. These keys are created from a passphrase that a human can remember but are much less secure against brute force attacks or guessing the passphrase.
Castellucci reports that such transactions were hijacked instantly when using random five-character passphrases.
Such efforts by cybercriminals can lead to massive botnets moving into the field of key-breaking and utilising mass computing resources for stealing funds directly from the wallets of those that have already mined or bought them, instead of going to the trouble of mining the currency themselves. It seems digital wallets are just as vulnerable as their physical equivalents.
In conclusion, cybercriminals have yet again been quick to innovate in the use of emerging technologies.
We expect this wave of mining malware to keep growing and be a major source of innovation and revenue for attackers in the coming years – and a growing problem that the security industry needs to address. u www. intelligentciso. com | Issue 04
