Researchers Sound Alarm Over Malicious AWS Community AMIs

Researchers are sounding the alarm over what they say is a growing threat vector tied to Amazon Web Services and its marketplace of pre-configured virtual servers. The danger, according to researchers with Mitiga, is that threat actors can easily build malware-laced Community Amazon Machine Image...

The vulnerability of the vhost-crypto module in the libraries and drivers for fast packet processing in dpdk allows a hacker to gain access to confidential data.

The vulnerability of the vhost-crypto module in the libraries and drivers for fast packet processing in dpdk is related to a numerical overflow condition. Exploiting this vulnerability can allow an attacker to gain access to confidential data...

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...

Phirautee - A PoC Crypto Virus To Spread User Awareness About Attacks And Implications Of Ransomwares

A proof of concept crypto virus to spread user awareness about attacks and implications of ransomwares. Phirautee is written purely using PowerShell and does not require any third-party libraries. This tool steals the information, holds an organisation’s data to hostage for payments or permanentl...

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...

CVE-2020-0259

In androidverityctr of dm-android-verity.c, there is a possible way to modify a dm-verity protected filesystem due to improperly used crypto. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product:...

CVE-2020-8912 In-band key negotiation issue in AWS S3 Crypto SDK for GoLang

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

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-2020-8912

CVE-2020-8912 concerns the AWS S3 Crypto SDK for Go, affected in GoLang SDKs before version 2. The bug is in-band key negotiation which allows a user with write access to a bucket to alter the encryption algorithm of an object (e.g., switch from AES-GCM to AES-CTR). When combined with a decryptio...

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...
