Threat actors have been observed using malvertising attacks to distribute virtualized .NET malware loaders dubbed “MalVirt.” According to a Thursday advisory by SentinelOne, the new loaders leverage obfuscated virtualization techniques to avoid detection. “The loaders are implemented in .NET and use virtualization, based on the KoiVM virtualizing protector of .NET applications, in order to obfuscate

by Paul Ducklin The open source operating system distribution OpenBSD is well-known amongst sysadmins, especially those who manage servers, for its focus on security over speed, features and fancy front-ends.

Security experts claim to have discovered the first “cryptorom” scam applications to have successfully bypassed Apple’s strict App Store vetting processes.

by Paul Ducklin It’s been a newsworthy few weeks for password managers – those handy utilities that help you come up with a different password for every website you use, and then to keep track of them all. At the end of 2022, it was the turn of LastPass to be all over the news,

A critical new vulnerability disclosed by network-attached storage (NAS) vendor QNAP this week could be exploited on almost 30,000 devices globally, according to Censys. The security firm scanned the internet to find 67,415 hosts running QNAP-based systems around the world. Although it could only find the version number on 30,250 of them, a worrying 98%

by Paul Ducklin Another day, another access-token-based database breach. This time, the victim (and in some ways, of course, also the culprit) is Microsoft’s GitHub business. GitHub claims that it spotted the breach quickly, the day after it happened, but by then the damage had been done: On December 6, 2022, repositories from our atom,

A leading Taiwanese hardware manufacturer is urging its customers to patch a critical vulnerability in devices running the QTS or QuTS hero firmware.

In the late 1990s, Microsoft networking shed its opaque, proprietary nature and became an open standard known as CIFS,

Ukrainian cyber-experts have discovered multiple pieces of destructive malware that, earlier this month, were used in an attack targeting the country’s national news agency (Ukrinform). The country’s Computer Emergency Response Team (CERT-UA) revealed in an update that the attack was publicized on a Telegram channel “CyberArmyofRussia_Reborn” on January 17. After being asked by Ukrinform to

An operation responding to a Black Basta ransomware compromise has revealed the use of a new PlugX malware variant that can automatically infect any attached removable USB media devices.

by Paul Ducklin Over the years, we’ve written and spoken on Naked Security many times about the thorny problem of DNS hijacking. DNS, as you probably know, is short for domain name system, and you’ll often hear it described as the internet’s “telephone directory” or “gazetteer”. If you’re not familiar with the word gazeteer, it

A new string of attacks against East Asian organizations has been spotted by security researchers and attributed to the threat actor known as DragonSpark.

An increasing number of threat actors have started relying on the command-and-control (C2) framework Sliver as an open-source alternative to tools such as Metasploit and Cobalt Strike.

by Paul Ducklin Last year, on the last day of August 2022, we wrote with mild astonishment, and perhaps even a tiny touch of excitement, about an unexpected but rather important update for iPhones stuck back on iOS 12. As we remarked at the time, we’d already decided that iOS 12 had slipped (or perhaps

Security researchers have spotted another innovative technique phishing actors are using to bypass traditional security filters – this time using blank images. The email in question was detected by Check Point business Avanan, and arrived as a legitimate-looking DocuSign message. Although the link in the email body will take the user directly to a regular
