A threat actor working to further Iranian goals is said to have been behind a set of disruptive cyberattacks against Albanian government services in mid-July 2022. Cybersecurity firm Mandiant said the malicious activity against a NATO state represented a "geographic expansion of Iranian disruptive cyber operations." The July 17 attacks, according to Albania's National Agency of Information

This Tech Tip outlines how DevOps teams can address security integration issues in their CI/CD pipelines.

Ethermint is an Ethereum library. In Ethermint running versions before `v0.17.2`, the contract `selfdestruct` invocation permanently removes the corresponding bytecode from the internal database storage. However, due to a bug in the `DeleteAccount`function, all contracts that used the identical bytecode (i.e shared the same `CodeHash`) will also stop working once one contract invokes `selfdestruct`, even though the other contracts did not invoke the `selfdestruct` OPCODE. This vulnerability has been patched in Ethermint version v0.18.0. The patch has state machine-breaking changes for applications using Ethermint, so a coordinated upgrade procedure is required. A workaround is available. If a contract is subject to DoS due to this issue, the user can redeploy the same contract, i.e. with identical bytecode, so that the original contract's code is recovered. The new contract deployment restores the `bytecode hash -> bytecode` entry in the internal state.

A nascent service called Dark Utilities has already attracted 3,000 users for its ability to provide command-and-control (C2) services with the goal of commandeering compromised systems. "It is marketed as a means to enable remote access, command execution, distributed denial-of-service (DDoS) attacks and cryptocurrency mining operations on infected systems," Cisco Talos said in a report shared

zlib through 1.2.12 has a heap-based buffer over-read or buffer overflow in inflate in inflate.c via a large gzip header extra field. NOTE: only applications that call inflateGetHeader are affected. Some common applications bundle the affected zlib source code but may be unable to call inflateGetHeader (e.g., see the nodejs/node reference).

Weak permissions on the configuration file in the PAM module in Grommunio Gromox 0.5 through 1.x before 1.28 allow a local unprivileged user in the gromox group to have the PAM stack execute arbitrary code upon loading the Gromox PAM module.

do_request in request.c in muhttpd before 1.1.7 allows remote attackers to read arbitrary files by constructing a URL with a single character before a desired path on the filesystem. This occurs because the code skips over the first character when serving files. Arris NVG443, NVG599, NVG589, and NVG510 devices and Arris-derived BGW210 and BGW320 devices are affected.

At Black Hat USA, Igal Gofman plans to address how machine identities in the cloud and the explosion of SaaS apps are creating risks for IAM, amid escalating attention from attackers.

A dangerous VMware authentication-bypass bug could give threat actors administrative access over virtual machines.
