UPnProxy is alive and well. There are 277,000 devices, out of a pool of 3.5 million, running vulnerable implementations of UPnP. Of those, Akamai can confirm that more than 45,000 have been compromised in a widely distributed UPnP NAT injection campaign.
FritzFrog is a peer-to-peer botnet, which means its command and control server is not limited to a single, centralized machine, but rather can be done from every machine in its distributed network. In other words, every host running the malware process becomes part of the network, and is capable of sending, receiving, and executing the commands to control machines in the network.
CISA Adds One Known Exploited Vulnerability to Catalog
CISA has added one new vulnerability to its Known Exploited Vulnerabilities Catalog, based on evidence that threat actors are actively exploiting the vulnerability listed in the table below. These types of vulnerabilities are a frequent attack vector for malicious cyber actors of all types and pose significant risk to the federal enterprise.

Uncovering thousands of unique secrets in PyPI packages
Security Researcher Tom Forbes worked with the GitGuardian team to analyze all the code committed to PyPi packages and surfaced thousands of hardcoded credentials.
In a first, cryptographic keys protecting SSH connections stolen in new attack | Ars Technica
An error as small as a single flipped memory bit is all it takes to expose a private key. The vulnerability occurs when there are errors during the signature generation that takes place when a client and server are establishing a connection. It affects only keys using the RSA cryptographic algorithm, which the researchers found in roughly a third of the SSH signatures they examined. That translates to roughly 1 billion signatures out of the 3.2 billion signatures examined. Of the roughly 1 billion RSA signatures, about one in a million exposed the private key of the host.
A Closer Look at ChatGPT's Role in Automated Malware Creation
As the use of ChatGPT and other artificial intelligence (AI) technologies becomes more widespread, it is important to consider the possible risks associated with their use. One of the main concerns surrounding these technologies is the potential for malicious use, such as in the development of malware or other harmful software. Our recent reports discussed how cybercriminals are misusing the large language model’s (LLM) advanced capabilities: We discussed how ChatGPT can be abused to scale manual and time-consuming processes in cybercriminals’ attack chains in virtual kidnapping schemes. We also reported on how this tool can be used to automate certain processes in harpoon whaling attacks to discover “signals” or target categories.
The Mirai Confessions: Three Young Hackers Who Built a Web-Killing Monster Finally Tell Their Story | WIRED
Netflix, Spotify, Twitter, PayPal, Slack. All down for millions of people. How a group of teen friends plunged into an underworld of cybercrime and broke the internet—then went to work for the FBI.
LockBit ransomware group assemble strike team to breach banks, law firms and governments.
Recently, I’ve been tracking LockBit ransomware group as they’ve been breaching large enterprises: I thought it would be good to break down what is happening and how they’re doing it, since LockBit are breaching some of the world’s largest organisations — many of whom have incredibly large security budgets. Through data allowing the tracking of ransomware operators, it has been possible to track individual targets. Recently, it has become clear they have been targeting a vulnerability in Citrix Netscaler, called CitrixBleed. Prior reading:
CacheWarp is a new software fault attack on AMD SEV-ES and SEV-SNP. It allows attackers to hijack control flow, break into encrypted VMs, and perform privilege escalation inside the VM.
Google researchers discover 'Reptar,’ a new CPU vulnerability
A new CPU vulnerability, ‘Reptar,’ found by Google researchers, has been patched by Google and Intel. Here’s what you need to know. ... The impact of this vulnerability is demonstrated when exploited by an attacker in a multi-tenant virtualized environment, as the exploit on a guest machine causes the host machine to crash resulting in a Denial of Service to other guest machines running on the same host. Additionally, the vulnerability could potentially lead to information disclosure or privilege escalation.
District of Puerto Rico | Russian and Moldovan National Pleads Guilty to Operating Illegal Botnet Proxy Service that Infected Tens of Thousands of Internet-Connected Devices Around the World | United States Department of Justice
A Russian and Moldovan national pled guilty to three counts of violating 18 U.S.C. § 1030(a)(5)(A) Fraud and Related Activity in Connection with Computers. The FBI today revealed US law enforcement’s dismantlement of a botnet proxy network and its infrastructure associated with the IPStorm malware. According to online reports, the botnet infrastructure had infected Windows systems then further expanded to infect Linux, Mac, and Android devices, victimizing computers and other electronic devices around the world, including in Asia, Europe, North America and South America.
Today, Microsoft released patches for 64 different vulnerabilities in Microsoft products, 14 vulnerabilities in Chromium affecting Microsoft Edge, and five vulnerabilities affecting Microsoft's Linux distribution, Mariner. Three of these vulnerabilities are already being exploited, and three have been made public before the release of the patches.
We have a CPU mystery! We found a way to cause some processors to enter a glitch state where the normal rules don’t apply, but what does that mean…? If you’re interested what can go wrong inside modern CPUs, read on!
