But he added that cybercriminals typically have access to botnets -- large collections of infected computers -- that are able to achieve the same task without detection.
What do botnets have to do with crawling the web for unsecured devices? I'm not sure I understand the correlation.
- AnIrishDuck 14y agoThe article is full of technical misconceptions, but if I had to guess: 1) Botnets give you a ton of bandwidth to run port scans or crawling searches. 2) They also allow you to "map" port scans or searches over thousands of computers (e.g. one computer in the botnet scans one specific port times ten thousand ports), obscuring the fact that a scan is even occurring.
- dmiladinov 14y agoI think it's because you can use botnets to divide up the vast IPv4 search space among the individual bots and crawl it exponentially faster.
- Houshalter 14y agoExponentially?
- mcpherrinm 14y agoIf you assume the bots are infecting hosts they scan, then yes.
- mh- 14y agoI think exponentially is the new literally.
