Week in review

AUSCERT Week in Review for 29th June 2018

AUSCERT Week in Review
29 June 2018

Greetings,

Business Email Compromise (BEC) has been in the news this week, with a flurry of incidents and investigations. Do you have two-factor authentication enabled on your Outlook accounts? It’s the single easiest way to foil these attacks.

Privacy and consent haven’t been solved yet, but the revelation that the HealthEngine booking system was selling personal health data to ambulance-chasers has made waves this week.

The Drupalgeddon v3 vulnerability is still being exploited by cryptocurrency miners. If you haven’t patched yet, please make it a priority.

Of the data breaches around the world, three caught our eye: Adidas, Exactis (a marketing and aggregation firm) and Ticketmaster. Exactis in particular may have exceeded the infamous Equifax breach in scope.

In the news this week:

Tracked as CVE-2018-7602 and considered a highly critical issue that could result in remote code execution, the vulnerability impacts Drupal’s versions 7 and 8 and was addressed in April this year.

Last month, hackers were observed targeting both security vulnerabilities to deliver a variety of threats, including cryptocurrency miners, remote administration tools (RATs) and tech support scams.

Trend Micro now says they noticed network attacks exploiting CVE-2018-7602 to turn affected systems into Monero-mining bots. As part of the observed incidents, the exploit fetches a shell script that retrieves an Executable and Linkable Format-based (ELF) downloader.
