Here are a couple of snippets from Perth Now Sunday Times in Australia
ANOTHER large-scale, stealthy cyber-attack is underway on a scale that could dwarf last week’s assault on computers worldwide.
The new attack targets the same vulnerabilities the WannaCry ransomware worm exploited but, rather than freeze files, uses the hundreds of thousands of computers believed to have been infected to mine virtual currency.
“It uses the hacking tools recently disclosed by the NSA and which have since been fixed by Microsoft in a more stealthy manner and for a different purpose,” he said.
Instead of completely disabling an infected computer by encrypting data and seeking a ransom payment, Adylkuzz uses the machines it infects to “mine” in a background task a virtual currency, Monero, and transfer the money created to the authors of the virus.
…symptoms of the attack include loss of access to shared Windows resources and degradation of PC and server performance, effects which some users may not notice immediately.
