Threat Awareness – BEC and VEC and MPI (Multi-Persona Impersonation), Oh My!

Business email compromise (BEC) and vendor email compromise (VEC) are accurately and often discussed as impersonation-style cyber attacks where threat actors purport to be someone we have an existing trust relationship with. The intent of this ruse is to give phishing ploys a level of credibility to increase the chance of success. Some impersonation-style attacks are little more than amateurs attempting to spoof a trusted sender.

Threat Awareness – Microsoft Teams GIFs can be exploited for GIFShell Attacks

Threat Actors could exploit GIFs in Microsoft Teams to conduct phishing attacks, exfiltrate data, bypass security controls, and perform command execution via a novel attack technique dubbed “GIFShell.” The new attack technique chains together multiple security vulnerabilities in Microsoft Teams to compromise potential victims.

Security Awareness – Ransomware Threat Actors Adopting New Encryption Tactic

An increasing number of ransomware gangs are embracing a new tactic that allows them to encrypt their victims' systems faster while reducing the odds of being detected, according to a new report from SentinelLabs. This tactic is known as intermittent encryption and involves encrypting only portions of the targeted files' content, which still renders the data unrecoverable without a valid decryptor+key.

Security Awareness – North Korean Lazarus Group Targeted Energy Providers across the Globe

The North Korean sponsored advanced persistent threat (APT) Lazarus Group has been targeting energy providers across the world since February 2022 and employing new malware in their attacks, according to security researchers at Cisco Talos. Lazarus Group threat actors gain initial access via the exploitation of the Log4j vulnerability on exposed VMware Horizon servers. After gaining initial access, the attackers establish persistence on the victim networks’, conduct lateral movement, and deploy malware.

Cyber Resilience – Asset Visibility is Key First Step in Overall Cybersecurity

Understanding all the systems and devices that make up your organization’s network is a critical first step in establishing a cyber risk management strategy. Since you cannot defend or secure what you do not know you have, performing asset inventories to gain network visibility is critical for all organizations large and small. According to Tenable, organizations that have full network visibility “are better positioned to understand where the greatest risks are within their environment and start taking the necessary steps to mitigate risk where it matters most.”

Security Awareness – Half of Firms Report Supply Chain Ransomware Compromise

More than half of companies surveyed worldwide know a partner or vendor that has been impacted by ransomware. Still, few organizations are working to address supply chain vulnerabilities, according to a new report from Trend Micro. To conduct its study, Trend Micro survey around 3000 IT leaders across 26 countries. Among other findings, the report discovered that around 25 percent of all data breaches are due to ransomware.

Security Awareness – Brand Impersonation and Social Engineering Still a Favorite Combination for Credential Phishing

Security researchers at Armorblox observed a recent phishing campaign utilizing a very convincing brand impersonation of American Express to fool victims and steal credentials. The phish includes an attachment purporting to be an urgent message informing the recipient that their account will be suspended unless they perform a mandatory account verification.
