Did you ever get that feeling that your computer was acting “funny” or was “too slow”, in an unusual sort of way? Or maybe you read a recent article about the latest malware or creepy hack attack that got you thinking about hijacked video cameras? Sometimes hacks can bypass your traditional antivirus or endpoint security. Every once in a while, I like to run the Trend Micro awesome free security scan.
There is nothing wrong with double checking your current security software! Two eyes are better than one. Trend Micro has a long track record in the security software world. They are well regarded and this is a very solid offering. Obviously, the fact that it is free makes it even better! It can be downloaded and quickly installed and run right away. Always run a full scan in this case [not the quick scan]- go big or go home, so to speak. If Trend Micro is currently in use, try the McAfee free option.
GitHub announced that it now supports Web Authentication (WebAuthn) for security keys. In addition to time-based one-time password (TOTP) applications and text messages, you can now also configure two-factor authentication using a security key.
Computer Antivirus software continues to be very relevant and necessary these days, despite the fact that social engineering and malware exploits may be more dangerous and numerous. Of course, most antivirus programs these days are combined with other security services [suites] or they do account for the various methods hackers employ to cause trouble, get your information or money. Everyone should use one of the top 4 or 5 rated antivirus programs (Norton, McAfee, ESET etc.) or at least Windows Defender on a PC, if you are on a budget.
But if you get a file or website virus type warning, it is always best to double check or cross reference from VirusTotal.Com. This super useful site allows for uploading files to the site for a quick analysis. Your antivirus would likely quarantine or delete a suspicious file but it is possible a mistake was made, so why not double check? And it is free! Also, any file can be uploaded for a quick ‘virus check’, not just the files giving warning etc. from a scan application. Finally, actual web site addresses can be checked. This can be useful if you are on a site that is acting slow, unusual or one that gives you that weird, uncertain feeling.
Site summary services:
“Any user can select a file from their computer using their browser and send it to VirusTotal. VirusTotal offers a number of file submission methods, including the primary public web interface, desktop uploaders, browser extensions and a programmatic API. The web interface has the highest scanning priority among the publicly available submission methods. Submissions may be scripted in any programming language using the HTTP-based public API.
As with files, URLs can be submitted via several different means including the VirusTotal webpage, browser extensions and the API.
Upon submitting a file or URL basic results are shared with the submitter, and also between the examining partners, who use results to improve their own systems. As a result, by submitting files, URLs, domains, etc. to VirusTotal you are contributing to raise the global IT security level.”
Example of a random Windows executable file [from System32 folder] results, below.
This is a safe, standard Windows master boot record related file, called “MBR2GPT”. I know it is safe, but, this is to give a demo of the positive results. If you see a file, any file, that looks suspicious or maybe have never seen before, upload it and see for yourself.
In a nutshell: the cybersecurity companies that design software that is intended to protect our computers … got hacked. Therefore, it is fully possible that now the hackers understand the defense mechanisms of the companies that fight cybersecurity, at least at the PC, Mac, workstation level and maybe more. This is not good!
Details are sketchy, as is common with these hacks, and two of the victims [Norton and McAfee] deny any breach, but Trend Micro admits a breach occurred. Although Trend said the hack only affected their “lab”, this does not necessarily make customers feel any better about it, given they are in the CYBERSECURITY industry.
This “Check Point” [or “ThreatCloud”] cyber attack map is mesmerizing. It is a live cyber or hack attack map containing oodles of attack lines that follow live, currently in progress cyber attacks. The threat map lists the time, the attack name [or virus or hack type], the source and the intended victim location: the target.
The attacks are unrelenting and endless and the lines are ongoing in this dynamic situation.
One take away I have is that every country in the world can be a cyber target. Likewise, attack sources seem to come from almost anywhere in the world, although ‘botnets’ [a group of secretly hacked, controlled computers] are likely a major factor in this.
This new Azure Sentinel offering from Microsoft looks fantastic. It looks to improve the usual “SEIM” offerings out there. SEIM is an acronym for security information and event manager platform. This product or service can be set up and viewed right with Azure, of course.
The usual [overpriced] “SEIM” tools do not quite have the full Cloud ready set of tools available with Sentinel. Sentinel is, in a nutshell:
“Azure Sentinel is a cloud-native security information and event manager (SIEM) platform that uses built-in AI to help analyze large volumes of data across an enterprise—fast. Azure Sentinel aggregates data from all sources, including users, applications, servers, and devices running on-premises or in any cloud, letting you reason over millions of records in a few seconds. “
This is actually [indirectly] courtesy of the US Government’s NSA, from a few years ago. They actually created the code that exploits Microsoft Servers that face the internet directly.
“It’s been almost a week since the City of Atlanta was hit by a ransomware attack, which encrypted city data and led to the shutdown of some services. Mayor Keisha Lance Bottoms said in a press conference Monday that the city’s government is working on recovering the network after ransom notes appeared on computer displays on Thursday afternoon. The city has hired local cybersecurity firm SecureWorks to assess the situation.
Reports say the notorious SamSam ransomware was used in the Atlanta attack, which exploits a deserialization vulnerability in Java-based servers. Details of the attack remain largely unknown, but an early investigation may have identified who is behind the attack, said SecureWorks chief executive Michael Cote. Almost a million dollars has been reaped from other businesses that were infected and paid the ransom. It’s not known if Atlanta will pay the ransom.”
“China is in the lead” … of blocked countries. My humble website is constantly being sniffed at from the outside. To me it makes no sense on the surface – I have no confidential data or business secrets whatsoever. I do not do eCommerce or any business transactions for that matter. I do not even make poor stock market predictions!
But it makes sense to the potential intruders. These are likely bots just doing recon, searching for WordPress, Plugin or theme weaknesses and other possible pots of gold. Thankfully, I am fully invested in “WordFence”, an outstanding WordPress firewall.
