The remaining issues that haven't yet been fixed are all inherited from TrueCrypt. Idrassi clarified on Twitter Tuesday that all issues specific to VeraCrypt and one inherited from TrueCrypt were fixed in VeraCrypt 1.19. This is what made TrueCrypt so popular in the first place and why its sudden demise left a big void. Microsoft's BitLocker disk encryption technology is only included in the professional and enterprise versions of Windows and most other solutions are commercial. While VeraCrypt is available for multiple operating systems, it is on Windows where it has the biggest impact, because there aren't many free full-disk encryption options on Windows that also allow encrypting the OS drive. The auditors thanked Mounir Idrassi and his company Idrix for working with them on resolving the identified problems and for developing what they called a "crucial open-source software" program. The XZip and XUnzip libraries which were used in VeraCrypt for various operations also had flaws, so the developer decided to replace them with the more modern and secure libzip library. Users will still be able to decrypt and access existing containers encrypted with this algorithm, but won't be able to create new ones. This makes it much less mature than the rest of the code, so it's understandable that it would have more flaws in it.Īnother change made following the audit was the removal of the Russian GOST 28147-89 encryption standard, whose implementation the auditors deemed unsafe.

VeraCrypt's UEFI-compatible bootloader - a first for open-source encryption programs on Windows - was released in August and is the biggest addition to the TrueCrypt code base made by VeraCrypt's lead developer, Mounir Idrassi. TrueCrypt, which serves as the base for VeraCrypt, never had support for UEFI, forcing users to disable UEFI boot if they wanted to encrypt the system partition. Many flaws were located and fixed in VeraCrypt's bootloader for computers and OSes that use the new UEFI (Unified Extensible Firmware Interface) - the modern BIOS. Some of them are unpatched issues previously found by an older TrueCrypt audit.

As a result, it's urging corporations and IT administrators to install the patch as soon as possible.The audit, which was performed by French cybersecurity firm QuarksLab and was sponsored through the Open Source Technology Improvement Fund (OSTIF), found eight critical vulnerabilities, three medium risk vulnerabilities and 15 low-impact flaws. However, the security firm warns it's possible other groups may have uncovered details of the vulnerability.

The issue is specific to Windows 10, as other Windows operating systems, including Windows 7 and 8, are unaffected by this flaw. While this vulnerability is not currently known to be used in active attacks, it is essential that customers apply Windows updates to address this vulnerability as soon as possible,” the company wrote in a security advisory.Ĭheck Point discovered the flaw in May, and reported it to Microsoft. The latest Windows Defender version seems to have introduced this flaw alongside with the attempts of Microsoft to solve other problems in its software. “Windows DNS Server is a core networking component. Only machines used for DNS purposes are vulnerable, though. Still, the company has rated the flaw's base severity with the highest possible 10.0 risk score, and says it affects all Windows server versions. Making matters worse: the vulnerability is wormable a hacker could unleash an automated attack on the internet designed to hijack one server and then another, resulting in numerous hijacked Windows DNS servers.įortunately, Microsoft released a patch, which is already rolling out to machines with automatic updates enabled. The hijacked servers could also send the internet traffic to hacker-controlled domains designed to log your information, including passwords. With such control, the hacker could reroute the network traffic to intercept user emails and shut down access to websites. “These servers are present in every organization, and if exploited, would give a hacker Domain Administrator rights over the server,” Check Point wrote in a Tuesday report.
