TOP VULNERABILITY THIS WEEK: New exploit kit Spelevo uses old tricks
=========================================================
NOTABLE RECENT SECURITY ISSUES
SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Spelevo exploit kit pops up to deliver banking trojans
Description: Researchers at Cisco Talos discovered a new exploit kit known as “Spelevo.” While exploit kit activity has quieted down over the past few years, this new campaign uses some old tricks — such as exploiting Adobe Flash Player vulnerabilities — to infect victims. It then delivers various payloads, but mainly banking trojans such as IcedID and Dridex. The actors behind Spelevo seem to be strictly financially motivated.

Title: Firefox patches critical zero-day used to target Macs
Description: Firefox patched a series of bugs in its latest update, but most notably fixed a vulnerability that attackers exploited to install cryptocurrency miners. Last week, the web browser released a fix for a code-execution vulnerability in a JavaScript programming method known as “Array.pop,” and then a sandbox breakout bug the next day. Two new Snort rules from Talos protect against the Array vulnerability.
