Check Point’s latest Global Threat Impact Index detected a continued increase in the number of organizations being targeted with Exploit Kits, as Rig EK became the most prevalent form of attack, while there was also a resurgence in the Slammer worm detected, with 4% of businesses impacted.
Slammer resurfaced following a short hiatus, jumping back into the top three most popular malware families. The Slammer worm first emerged in 2003 and spread extremely rapidly. It was developed to target Microsoft SQL 2000, and propagated so quickly that it was able to cause a denial of service condition on some affected targets. This is the second time the worm has entered the malware top ten in recent months, showing how even decades-old malware can successfully resurface.
It’s the second month running that seemingly outdated malware variants have reappeared, following the reemergence in March 2017 of Exploit Kits, that are designed to discover and exploit vulnerabilities on machines in order to download and execute further malicious code. This trend underlines how important it is to remain vigilant for a broad spread of threats and attack vectors, even those that appear to have fallen out of general usage.
The top ten global malware families reveal a wide range of attack vectors and targets, which impact all stages of the infection chain. The most common malware in April were Rig EK and HackerDefender, impacting 5% and 4.5% of organizations worldwide respectively, while the Slammer worm came in third impacting 4% of organizations.

Cybercriminals will always choose to adapt the tools they already have at their disposal if possible, rather than developing brand new ones, simply because it’s faster and more cost-effective. It’s a vital warning to organizations in multiple sectors – you must remain vigilant and deploy sophisticated security systems that protect against a wide range of attack types, such as Check Point’s SandBlast™ Zero-Day Protection and Mobile Threat Prevention.
