If they were really closed circuit devices, they have no business on the open internet anyway.
Researchers have uncovered two flaws that leave more than 100,000 NUUO-powered internet-connected surveillance cameras open to remote takeover. Tenable Research on Monday laid claim to discovering two bugs in NUUO's Network Video Recorder firmware that can be exploited to covertly access a camera's video feed or simply take …
While someone might buy CCTV cameras to monitor day to day activity -- to detect shoplifting for example -- they might also buy them to monitor for vandalism, theft, etc when no one is around. That implies sending the signal to somebody who will watch for suspicious activity in the wee hours of the morning. Some of these things are probably going to be on the internet. Conceptually, there should be a properly configured firewall between the camera and a bored hacker in Budapest. But in practice a lot of them won't have firewalls at all, and some that do will have misconfigured firewalls.
What to do about that situation ... I haven't the slightest. And neither, really, does anyone else.
My thoughts exactly...
I'm still trying to determine how so many of these devices are accessible.. typically they are put on a WIFI network, which 99.999% has a NAT Firewall/Router in front of it!
So are there really so many morons that are using IP or Port forwarding to these devices? Or am I being a moron and not realising there is another avenue of attack!
The criminals behind the Emotet botnet – which rose to fame as a banking trojan before evolving into spamming and malware delivery – are now using it to target credit card information stored in the Chrome web browser.
Once the data – including the user's name, the card's numbers and expiration information – is exfiltrated, the malware will send it to command-and-control (C2) servers that are different than the one that the card stealer module uses, according to researchers with cybersecurity vendor Proofpoint's Threat Insight team.
The new card information module is the latest illustration of Emotet's Lazarus-like return. It's been more than a year since Europol and law enforcement from countries including the United States, the UK and Ukraine tore down the Emotet actors' infrastructure in January 2021 and – they hoped – put the malware threat to rest.
The botnet malware EnemyBot has added exploits to its arsenal, allowing it to infect and spread from enterprise-grade gear.
What's worse, EnemyBot's core source code, minus its exploits, can be found on GitHub, so any miscreant can use the malware to start crafting their own outbreaks of this software nasty.
The group behind EnemyBot is Keksec, a collection of experienced developers, also known as Nero and Freakout, that have been around since 2016 and have launched a number of Linux- and Windows-based bots capable of launching distributed denial-of-service (DDoS) attacks and possibly mining cryptocurrency. Securonix first wrote about EnemyBot in March.
A Russian operated botnet known as RSOCKS has been shut down by the US Department of Justice acting with law enforcement partners in Germany, the Netherlands and the UK. It is believed to have compromised millions of computers and other devices around the globe.
The RSOCKS botnet functioned as an IP proxy service, but instead of offering legitimate IP addresses leased from internet service providers, it was providing criminals with access to the IP addresses of devices that had been compromised by malware, according to a statement from the US Attorney’s Office in the Southern District of California.
It seems that RSOCKS initially targeted a variety of Internet of Things (IoT) devices, such as industrial control systems, routers, audio/video streaming devices and various internet connected appliances, before expanding into other endpoints such as Android devices and computer systems.
Windows and Linux systems are coming under attack by new variants of the HelloXD ransomware that includes stronger encryption, improved obfuscation and an additional payload that enables threat groups to modify compromised systems, exfiltrate files and execute commands.
The new capabilities make the ransomware, first detected in November 2021 - and the developer behind it even more dangerous - according to researchers with Palo Alto Networks' Unit 42 threat intelligence group. Unit 42 said the HelloXD ransomware family is in its initial stages but it's working to track down the author.
"While the ransomware functionality is nothing new, during our research, following the lines, we found out the ransomware is most likely developed by a threat actor named x4k," the researchers wrote in a blog post.
Microsoft is extending the Defender brand with a version aimed at families and individuals.
"Defender" has been the company's name of choice for its anti-malware platform for years. Microsoft Defender for individuals, available for Microsoft 365 Personal and Family subscribers, is a cross-platform application, encompassing macOS, iOS, and Android devices and extending "the protection already built into Windows Security beyond your PC."
The system comprises a dashboard showing the status of linked devices as well as alerts and suggestions.
Intezer security researcher Joakim Kennedy and the BlackBerry Threat Research and Intelligence Team have analyzed an unusual piece of Linux malware they say is unlike most seen before - it isn't a standalone executable file.
Dubbed Symbiote, the badware instead hijacks the environment variable (LD_PRELOAD) the dynamic linker uses to load a shared object library and soon infects every single running process.
The Intezer/BlackBerry team discovered Symbiote in November 2021, and said it appeared to have been written to target financial institutions in Latin America. Analysis of the Symbiote malware and its behavior suggest it may have been developed in Brazil.
Miscreants are reportedly exploiting the recently disclosed critical Windows Follina zero-day flaw to infect PCs with Qbot, thus aggressively expanding their reach.
The bot's operators are also working with the Black Basta gang to spread ransomware in yet another partnership in the underground world of cyber-crime, it is claimed.
This combination of Follina exploitation and its use to extort organizations makes the malware an even larger threat for enterprises. Qbot started off as a software nasty that raided people's online bank accounts, and evolved to snoop on user keystrokes and steal sensitive information from machines. It can also deliver other malware payloads, such as backdoors and ransomware, onto infected Windows systems, and forms a remote-controllable botnet.
A security flaw in Apple's Safari web browser that was patched nine years ago was exploited in the wild again some months ago – a perfect example of a "zombie" vulnerability.
That's a bug that's been patched, but for whatever reason can be abused all over again on up-to-date systems and devices – or a bug closely related to a patched one.
In a write-up this month, Maddie Stone, a top researcher on Google's Project Zero team, shared details of a Safari vulnerability that folks realized in January this year was being exploited in the wild. This remote-code-execution flaw could be abused by a specially crafted website, for example, to run spyware on someone's device when viewed in their browser.
While enterprises are still waiting for Microsoft to issue a fix for the critical "Follina" vulnerability in Windows, yet more malware operators are moving in to exploit it.
Microsoft late last month acknowledged the remote code execution (RCE) vulnerability – tracked as CVE-2022-30190 – but has yet to deliver a patch for it. The company has outlined workarounds that can be used until a fix becomes available.
In the meantime, reports of active exploits of the flaw continue to surface. Analysts with Proofpoint's Threat Insight team earlier this month tweeted about a phishing campaign, possibly aligned with a nation-state targeting US and European Union agencies, which uses Follina. The Proofpoint researchers said the malicious spam messages were sent to fewer than 10 Proofpoint product users.
The Gallium group, believed to be a Chinese state-sponsored team, is going on the warpath with an upgraded remote access trojan (RAT) that threat hunters say is difficult to detect.
The deployment of this "PingPull" RAT comes as the gang is broadening the types of organizations in its sights from telecommunications companies to financial services firms and government entities across Asia, Southeast Asia, Europe and Africa, according to researchers with Palo Alto Networks' Unit 42 threat intelligence group.
The backdoor, once in a compromised system, comes in three variants, each of which can communicate with the command-and-control (C2) system in one of three protocols: ICMP, HTTPS and raw TCP. All three PingPull variants have the same functionality, but each creates a custom string of code that it sends to the C2 server, which will use the unique string to identify the compromised system.
