Winter Olympics hit by cyberattack
The Winter Olympics opening ceremony was hit by a cyberattack, causing internet and WiFi shutdowns across the games. South Korea's defense ministry and cybersecurity experts are included in the taskforce investigating the attack, but the possible culprit is being kept under wraps.

Coinhoarder: The bitcoin phishing ring
Bitcoin phishing is a relatively new thing, whereby criminals make fake sites but find some way to mask the difference in web addresses to appear legitimate.
Researchers at Cisco Talos report in the case of phishing group Coinhoarder, the group buys Google Adwords ads, then use the ads to pose as legitimate bitcoin wallet site Blockchain.info, complete with similar looking phishing webpage.
The attack is apparently quite lucrative, with the group managing to net over $50 million over the past 3 years.
Cryptominers take center stage
In addition to Bitcoin phishing websites, malware that aims to use your computers and Android devices to mine for cryptocurrency has also become prevalent.
At least 4,200 websites were affected by cryptocurrency mining malware after a browser plugin used on those sites – the Browsealoud plugin by TextHelp – was apparently hacked to generate cryptocurrency for the hacker. The Browsealoud plugin hack mined Monero cryptocurrency for about 4 hours for visitors of those affected websites before being taken down.
Meanwhile, a Monero cryptocurrency miner was also discovered on Android devices. Presumably millions of Android users hit by the cryptomining campaigfn were redirected to a browser page designed to perform in-browser cryptomining, and which required users to fill in a Captcha to turn off.
