New insight from blockchain analysis company, Chainalysis, shows that activity involving known ransomware crypto addresses has grown over the last 18 months, despite a downfall of other malicious activity. When I cover reports, there’s an understanding that the accuracy of the data provided is dependent on the number of organizations responding to a survey, the geos and industries represented, etc.
Since December 22nd, 2022, there has been an increase in malware sent via Phishing emails via a OneNote attachment. As with most phishing emails, the end user would open the OneNote attachment but unlike Microsoft Word or Microsoft Excel, OneNote does not support macros. This is how threat actors previously launched scripts to install malware.
As the rate of ransomware attacks steadily increased over time, there are clear indicators as to how these attacks are starting and, therefore, what can be done to stop them. With the exception of the Verizon Data Breach Investigations Report, we rarely get insight into specific industry verticals.
Ransomware and cyberattacks are on the rise, and that’s a deeply concerning thought for technology leaders. Considering what a breach could cost, and how long it would take to rectify, it’s no wonder risk mitigation and response is at the forefront of every CTO’s mind. Ransomware is a type of malicious software that blocks access to a computer system or encrypts files until a ransom is paid. It’s often spread through phishing emails or infected websites.
If your organization uses Microsoft Teams, then you definitely want to hear about a new way bad actors are exploiting this newly discovered cyber attack tool. "TeamsPhisher," a new tool recently discovered on GitHub, gives cybercriminals a new way to deliver malicious files directly to any Teams user. The genesis of this new cyber attack tool was published by the US Navy Red Team due to a recently discovered vulnerability in Microsoft Teams.
Apparently expanding efforts outside of Southeast Asian countries, this threat group’s known malware has shown up in a European healthcare facility, raising concerns for USB-based attacks. You’d think that literally no one uses USB drives anymore, making them a very improbable attack vector. And yet, the Camaro Dragon APT group has been tracked by security researchers at Check Point for well over a year, with them finding instances of attacks throughout all of last year and into this year.
On July 6th, the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), the Multi-State Information Sharing and Analysis Center (MS-ISAC), and the Canadian Centre for Cyber Security (CCCS) released an advisory highlighting the newly identifying Truebot malware variants. Truebot (also known as Silence Downloader) is a botnet that has been used by the CL0P ransomware gang to collect and exfiltrate stolen target victim information.
