As a principal security researcher on Corelight’s Labs team, I help to solve difficult network security research problems at scale. Corelight’s customers might recognize some of my work if you see the packages “VPN Insights” or “App ID” on your sensors. Outside of my day-to-day role, I have a hobby podcast called eCrimeBytes where we lightheartedly discuss an electronic crime case each week.
One thing is becoming evident as ransomware attacks increase in frequency and impact: businesses can take additional precautions. Unfortunately, many companies are failing to do so. Most victims are sufficiently warned about potential weaknesses yet unprepared to recover when hit. Robust ransomware prevention is more important than ever. This becomes very clear when you consider what causes the majority of ransomware attacks nowadays. Some are caused by errors that are easily avoidable.
It’s not a mystery that eBPF (Extended Berkeley Packet Filter) is a powerful technology, and given its nature, it can be used for good and bad purposes. In this article, we will explore some of the offensive capabilities that eBPF can provide to an attacker and how to defend against them.
British Intelligence has come up with a potentially very effective means to disrupt ransomware attacks, but there seems to still be a few kinks in the system. The phone rings at your U.K. office and it’s the U.K. government’s National Cyber Security Centre (NCSC) letting you know they’ve detected a potential cyberattack.
In the realm of cybersecurity, danger hides where we least expect it and threats never, ever, go out of style! Over the past few months, Trustwave SpiderLabs has seen a rising trend in threat actors employing PDF documents to gain initial access through email-borne attacks. Though the use of PDF files as a malicious vector is not a novel approach, it has become more popular as threat actors continue to experiment with techniques to bypass conventional security controls.
