Mysterious Silver Sparrow Malware Found Nesting on 30K Macs

Hard on the heels of a macOS adware being recompiled to target Apple’s new in-house processor, researchers have discovered a brand-new family of malware targeting the platform. Curiously, in the samples seen so far by analysts at Red Canary, the malware dubbed Silver Sparrow has been executing on...

Common Security Misconfigurations and Their Consequences

Everyone makes mistakes. That one sentence was drummed into me in my very first job in tech, and it has held true since then. In the cybersecurity world, misconfigurations can create exploitable issues that can haunt us later - so let's look at a few common security misconfigurations. The first o...

CVE-2020-8912

A flaw was found in the AWS S3 Crypto SDK where algorithm parameters for the data encryption key are not authenticated. This flaw allows attackers with S3 bucket write access to change the negotiated encryption algorithm, potentially providing viable brute force methods to recover plaintext. This...

CVE-2020-8911

A flaw was found in the AWS S3 Crypto SDK that allows users to encrypt files stored in S3 buckets with AES-CBC, without computing a MAC on the data. This allows for a padding oracle, enabling attackers with both write access to the target S3 bucket and the ability to observe the result of valid...

CVE-2020-8912

A vulnerability in the in-band key negotiation exists in the AWS S3 Crypto SDK for GoLang versions prior to V2. An attacker with write access to the targeted bucket can change the encryption algorithm of an object in the bucket, which can then allow them to change AES-GCM to AES-CTR. Using this i...

CVE-2020-8911

A padding oracle vulnerability exists in the AWS S3 Crypto SDK for GoLang versions prior to V2. The SDK allows users to encrypt files with AES-CBC without computing a Message Authentication Code MAC, which then allows an attacker who has write access to the target's S3 bucket and can observe...

Authentication flaw

A vulnerability in the in-band key negotiation exists in the AWS S3 Crypto SDK for GoLang versions prior to V2. An attacker with write access to the targeted bucket can change the encryption algorithm of an object in the bucket, which can then allow them to change AES-GCM to AES-CTR. Using this i...

Design/Logic Flaw

A padding oracle vulnerability exists in the AWS S3 Crypto SDK for GoLang versions prior to V2. The SDK allows users to encrypt files with AES-CBC without computing a Message Authentication Code MAC, which then allows an attacker who has write access to the target's S3 bucket and can observe...

CVE-2020-8911

CVE-2020-8911 describes a padding oracle in the AWS S3 Crypto SDK for Go (older GoLang S3 encryption client). The vulnerability arises because AES-CBC encryption was used without a MAC, enabling an attacker with write access to the target S3 bucket to observe decryption outcomes and reconstruct p...

CVE-2020-8911 CBC padding oracle in AWS S3 Crypto SDK for GoLang

A padding oracle vulnerability exists in the AWS S3 Crypto SDK for GoLang versions prior to V2. The SDK allows users to encrypt files with AES-CBC without computing a Message Authentication Code MAC, which then allows an attacker who has write access to the target's S3 bucket and can observe...
