Because Windows executables haven’t wreaked enough damage on Windows computers, now you can use malformed MSI files to run malicious code on Linux systems. This scenario is possible because of a vulnerability discovered by German IT expert Nils Dagsson Moskopp, which he named “Bad Taste.” The vulnerability affects GNOME Files, formerly known as Nautilus, the default file manager/explorer for Linux distros using the GNOME desktop.
A seven-year old vulnerability in Samba—an open-source implementation of the SMB protocol used by Windows for file and printer sharing—was patched last May but continues to be exploited. According to a security advisory released by the company, the vulnerability allows a malicious actor to upload a shared library to a writable share, causing the server to load and execute it. If leveraged successfully, an attacker...

Over the weekend, Emsisoft security researcher xXToffeeXx discovered a new ransomware called Reyptson that is targeting Spanish victims. Since then, we have seen increased activity in the ransomware’s development. Today security researcher MalwareHunterTeam took a deeper look and noticed that Reyptson conducts its own spam distribution campaign directly from a victim’s configured Thunderbird email account.
This week we are going to take a look at Eternal Synergy, an SMBv1 authenticated exploit. This one is particularly interesting because many of the exploitation steps are purely packet-based, as opposed to local shellcode execution. Like the other SMB vulnerabilities, this one was also addressed in MS17-010 as CVE-2017-0143. The exploit works up to Windows 8, but does not work as written against any...

Data breaches aren’t slowing down. If anything, they’re set to break last year’s record pace. As noted by 24/7 Wall Street, the 758 breaches reported this year mark nearly a 30 percent increase from 2016. If cybercriminals keep it up, the total number of attacks could break 1,500 by the end of 2017. Recent research by the Ponemon Institute found that companies have a 1-in-4...
