Welcome to the Xopero Security Center! Another ransomware news? No, not this time. However, data can be lost in more ways than one. For example, as a result of an unplanned factory restore. No more than half a week ago WD My Book NAS users fell victim to such a massive “update” or rather some form of a cyberattack. As always, more information can be found below. In this review: Dell is having a serious problem. The pre-installed firmware updater available on their computers may expose almost 30 million users or if you like – 128 models of this manufacturer’s devices, to attack. Also: Microsoft tracks a new BazaCall malware campaign using a fake call center to trick you, and Linux Marketplace bugs allow wormable attacks. Let’s begin.

Welcome to the Xopero Security Center! It’s a strange, strange world we live in… There is a new malware primary designed to block victims from entering torrent sites and other services with pirated content. And it doesn’t look like some sophisticated anti-piracy operation – generally, specialists have no idea what is going on. Victims should prepare themselves for some future scam or 2nd attack. This news open today’s review but what else our team prepared for you? REvil Group is getting more active again – this time the ransomware has hit US nuclear weapons contractor. There is also a new SolarMarker campaign that uses SEO poisoning to infect targets with a remote access trojan. The last news reports malicious Minecraft modpacks that hit Google Play Store. Ready for more details? Then check the text below.

Welcome to the Xopero Security Center! This month’s patch harvest was an extremely big one. The IT world heated up the information about six new zero-days patched by Microsoft in recent days. No less serious update has got Android users. Google has released a fix for the critical RCE bug and other 90+ vulnerabilities … Let’s stop at Google for a little longer. Chrome also has got a series of urgent fixes – one of the bugs is currently being used in a series of attacks. Let’s not forget about the last data breaches and cyberattacks too. Electronic Arts, a game publisher that you probably associate with the FIFA series fell a victim to the hackers. They stole – among other things – Frostbite engine and FIFA 21 source codes. Details, as usual, can be found below.

Welcome to the Xopero Security Center! What technological news has captured the imagination of IT specialists and geeks around the world? There were quite a few of them, but we have selected four (plus 10 extra) most interesting. Today’s release opens the new strain of Barebones ransomware called Epsilon Red. Marvel’s comic book fans will probably be familiar with this name. What makes this “villain” different from other threats? Namely, the fact that it is basing the attack chain on PowerShell scripts. Another topic concerns vulnerabilities in Microsoft PatchGuard. The newly detected bug allows attackers to load malicious code directly into the Windows kernel. We also describe the changes that took place inside the Necro Python bot. The latest update brings a number of fresh features as well as exploits for 10 applications – including VMware. The last article is about malicious ads visible on the Google network that can be delivered to your computers by the info stealer.

Enough small talk it’s time to check the whole post.

Last week turned out to be extremely unfavorable for Apple. First, the world heard about a new 0-day vulnerability that allows attackers to secretly perform print screens. Yes, let’s forget about any privacy… And then just a few days later, news about M1RACLES has come to our attention too. What is all the hype about? The bug is a result of a flaw in the M1 design. And what is even worse… That information you will find below. In this issue, we also describe a new variant of the Rowhammer attack. Half-Double – this is the name it got – allows bypassing all current defenses. However, today’s Security Center opens the news about a new critical bug detected in VMware vCenter. Given the scale of the threat (9.8/10 CVSS!), exploiting the vulnerability is trivial. Hence the pressure from security experts and the vendor itself to urgently update vulnerable systems.

Welcome to the newest episode of the Xopero Security Center. What have we got in store this week? First, MountLocker ransomware has been enhanced with a new “skill”. The threat is now able to use Active Directory to efficiently search company networks and infect devices connected to it. We also describe the four most recent 0-day security vulnerabilities found in Android. We also introduce you to the new attack called scheme flooding. This is a very neat method of user profiling based on the applications installed on the device. Today’s release ends with the news about Mercedes. Researchers identified five vulnerabilities in the latest infotainment system in Mercedes-Benz cars. Are you curious and ready for more? Great, then let’s enjoy your ride… eh reading.

Welcome to the newest episode of the Xopero Security Center. What is a threat of the week this time? FragAttacks vulnerabilities have been part of Wi-Fi since its release in 1997. This means that most devices produced during the last 24 years are vulnerable to the attack. How severe is this new threat? To uncover this true check the whole post below.

In today’s Security Center, we revolve around big numbers. We will start with… Dell. The popular computer vendor has a serious problem. Due to a bug that is over 12 years old, millions of users are vulnerable to attack. 2nd: nearly 30% of all mobile phones can become the “entry point” for a more complex attack. The culprit? The Qualcomm’s Mobile Station Modem. 3rd: 21 serious vulnerabilities were detected in Exim mail servers. They are a kind of package, so they also got a collective name – 21Nails. Are they really the proverbial final nails in the coffin? Check for yourself. In this issue, we also describe the apps – downloaded more than 100 million times – with the hard-coded Amazon Web Services private keys. At this point, we can only say that the risk of cyber attacks is really high. Hungry for knowledge? Then please, go ahead and read the rest.

Many SMS scams are mostly focused on phishing and trying to trick the user into filling in a form with valuable credentials, FluBot differs from these threats and goes one step ahead. This new banking malware – described in today’s Security Center issue – tries to install malicious software on the phone itself and then uses the device to spread into the user’s contact network. And even if the success rate of this campaign will be low, with the number of SMS being sent out, it will be very profitable for threat actors. Who is behind this most ‘successful’ smishing campaign? How dangerous the FluBot really is? Check the blog post below – and don’t click on any suspicious link or download applications from unreliable sources.
