Check Point reveals top malware and vulnerabilities in April 2023
Check Point Software Technologies, a provider of cybersecurity solutions globally, has published its Global Threat Index for April 2023.
Last month, researchers uncovered a substantial Qbot malspam campaign distributed through malicious PDF files attached to emails seen in multiple languages.
Meanwhile, Internet-of-Things (IoT) malware Mirai made the list for the first time in a year after exploiting a new vulnerability in TP-Link routers, and Healthcare moved up to become the second most exploited industry, Check Point finds.
The Qbot campaign seen last month involves a new delivery method in which targets are sent an email with an attachment that contains protected PDF files. Once these are downloaded, the Qbot malware is installed on the device. Researchers found instances of the malspam being sent in multiple different languages, which means organizations can be targeted worldwide.
Last month also saw the return of Mirai, one of the most popular IoT malwares. Researchers discovered it was exploiting a new zero-day vulnerability CVE-2023-1380 to attack TP-Link routers and add them to its botnet, which has been used to facilitate some of the most disruptive distributed DDoS attacks on record. This latest campaign follows an extensive report published by Check Point Research (CPR) on the prevalence of IOT attacks.
There was also a change in impacted industries, with healthcare overtaking government as the second most exploited sector in April. Attacks on healthcare institutions have been well documented and some countries continue to face constant assaults. For example, cyber criminal group Medusa recently launched attacks on cancer facilities in Australia.
The industry remains a lucrative target for hackers as it gives them potential access to confidential patient data and payment information. It could have implications for pharmaceutical companies as it could lead to leaks regarding clinical trials or new medical drugs and devices.
Maya Horowitz, VP Research at Check Point Software, says, “Cyber criminals are constantly working on new methods to bypass restrictions and these campaigns are further proof of how malware adapts to survive.
“With Qbot on the…
