Researchers at Truesec are tracking a phishing campaign that’s distributing the DarkGate Loader malware via external Microsoft Teams messages. “On August 29, in the timespan from 11:25 to 12:25 UTC, Microsoft Teams chat messages were sent from two external Office 365 accounts compromised prior to the campaign,” the researchers write.

When the well-renowned Oracle database started penetrating the enterprise, database administrators typically backed up to tape and disk, with the former being the preferred target.

Qakbot, also known as Pinkslipbot, Qbot and Quakbot, is a notorious Banking Trojan designed to steal account credentials and online banking session information leading to account takeover fraud. Commonly distributed via malicious unsolicited email (malspam), Qakbot campaigns reportedly deployed ‘Cobalt Strike’ beacons likely in an attempt to move laterally as well as gaining persistency and establishing a robust communication channel back to the threat actor.

New data suggests that the gangs and toolkits behind current ransomware attacks are materially improving their abilities, resulting in a speeding up of attacks before defenses kick in. It’s the last thing we want to hear; the threat actors are winning. But, according to Sophos’ 2023 Active Adversary Report for Tech Leaders report – at least when looking at threat actor dwell time – it seems to be the case.

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.

In a new threat briefing report, Forescout Vedere Labs looks back at the most relevant cybersecurity events and data between January 1 and July 31, 2023 (2023H1) to emphasize the evolution of the threat landscape. The activities and data we saw during this period confirm trends we have been observing in our recent reports, including threats to unmanaged devices that are less often studied.

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.
