Why Red Team Testing Rules the Cloud

securityintelligence.com/posts/red-teaming-cybersecurity-rules-the-cloud/ Red team testing is a key way to help prevent data breaches today. Most cyber defense focuses on spotting openings and fixing general risks in your environment. Red teaming not only reduces risks, but also prevents possible breaches. Methods, such as threat modeling, static analysis and dynamic testing, reduce the attack surface but do not eliminate risk. With red teaming, your team encounters real-life attacks in a safe scenario, making them more prepared for the threats to come.

New Attack Could Let Hackers Clone Your Google Titan 2FA Security Keys

thehackernews.com/2021/01/new-attack-could-let-hackers-clone-your.html Hardware security keyssuch as those from Google and Yubicoare considered the most secure means to protect accounts from phishing and takeover attacks. But a new research published on Thursday demonstrates how an adversary in possession of such a two-factor authentication (2FA) device can clone it by exploiting an electromagnetic side-channel in the chip embedded in it. The vulnerability (tracked as CVE-2021-3011) allows the bad actor to extract the encryption key or the ECDSA private key linked to a victim’s account from a FIDO Universal 2nd Factor (U2F) device like Google Titan Key or YubiKey, thus completely undermining the 2FA protections.

Malicious Shell Script Steals AWS, Docker Credentials

www.trendmicro.com/en_us/research/21/a/malicious-shell-script-steals-aws-docker-credentials.html We recently spotted new attacks where, again, threat actors used shell scripts to perform their malicious activities. Based on previous attacks, these malicious scripts were typically used to deploy cryptocurrency miners. But recent cases involving these fresh samples highlighted how the scripts are developed, as they now serve other purposes besides being downloaders for cryptominers. Based on its Command and Control URLs, some strings, crypto keys, and the language used on the samples, we deduced that this latest attack came from the TeamTNT arsenal.
