Later today (December 15, 2016) we will be implementing a database change within the system that manages the naming of signatures.
I wanted to let you know as some of you may notice that the numbers at the end of the signature names may change slightly. This won't have any affect on detection, and is an optimization on our backend for detection distribution.
If there are any questions regarding this, please feel free to reach out to us on the ClamAV-Users list.
Thanks!

ClamAV friend and community signature contributor Arnaud Jacques from SecuriteInfo.com wrote a quick article about how to whitelist a signature in ClamAV that may be giving you problems.
Please take a look at this article on his website, for some quick instruction on how to prevent a potential disaster in your environment.

With the upcoming release of ClamAV 0.99.3 comes an important change for Windows users interested in compiling ClamAV from source. Version 0.99.3 marks the switch from Visual Studio 2013 (and earlier) to Visual Studio 2015. Among other things, the benefits of this switch include improved C99 compatibility and much less restrictive licensing for individuals, educators, OSS contributors, and small teams.
Please be aware, this update will break compatibility when compiling ClamAV on older versions of Visual Studio. Additionally, building the Installation Setup Projects requires a Microsoft-provided plugin which provides the necessary compilation support.

We'd like to welcome CRDF to the ClamAV Signature Detection Partner Program!
The CRDF is the first 3rd party Signature house we've integrated into the program. Their signatures are now being distributed to all ClamAV Virus database subscribers, officially signed by us, and distributed through the official mirror system.
If you visit ClamAV.net and file a false positive report against one of CRDF's signatures, they will also receive a copy of the False positive report at the same time we do.
You can keep abreast of who we bring into the Partner program on our Contact page on ClamAV.net, and we'll announce each new on here, on the ClamAV Blog. We have several more we are working on right now.
If you write ClamAV detection, and are interested in having it distributed to the entire ClamAV community, and receive donations and false positive reports from your signatures, please see our blog post about how to join the program.

Recently, a tweet and subsequent blog post on Errata Security describe some features of the ClamAV daemon (clamd) that may be misused toward information disclosures and denial of service attacks. We wanted to take the opportunity to inform the ClamAV community about the clamd configuration that may lead to these issues along with the steps and options for using clamd securely.
clamd is an optional feature of ClamAV providing local or remote host access to ClamAV's scanning engine through the clamd protocol. Several ClamAV commands communicate with clamd using the clamd protocol: clamdscan for virus scanning, clamdtop for clamd resource monitoring, and freshclam, when used in conjunction with clamd, to notify clamd to reload the virus database. Clamav-milter and some third party programs use the clamd protocol as well. The clamd protocol is fully described in the clamd man-page.
This feature, off by default, requires manual configuration. In order to use clamd, an installation must select a socket type in clamd configuration file, clamd.conf. The installation has two choices for the type of socket. Their configuration parameter names are LocalSocket and TCPSocket. LocalSocket, available on Unix based systems, is not vulnerable to the information disclosure or the DoS. However, all of the programs communicating with clamd must reside on the same host system with clamd. The TCPSocket option enables communication from remote hosts, but care must be taken to protect the ingress network interfaces. An additional clamd parameter, TCPAddr, may be used to designate which network interfaces will accept clamd TCP connection requests. Those interfaces need to be protected, such as though the use of firewall or other network security mechanisms. This will ensure that unwanted clamd requests will be blocked. Additional information on the clamd configuration parameters may be found in the clamd.conf man-page and in the sample clamd configuration file distributed with ClamAV.
Finally, note that the clamscan command, and other software using the libclamav API directly, do not use clamd and therefore are not affected by this configuration.

As many of you know, over the past several years, we’ve been retooling the entire backend of ClamAV.net’s signature management system to handle a more streamlined release method and signature generation system. Now that this work is complete, we’re reaching out to those of you in our ClamAV community that manage some form of third party ClamAV signature distribution systems.
We would like to potentially incorporate the feeds that you are producing into the official feed coming from our mirror network at ClamAV, out to the community. We are going to ensure proper attribution for everyone’s work within the signature name.
We haven’t determined what this will look like, but what we would like to see is the name of the feed, not only in the signature name, but a table to be maintained on ClamAV.net ensuring the proper mapping from signature name to your website (and donation system, if you have one).
We would be responsible for the “dropping” of a False positive prone ClamAV sig from the official db, however, our intention is to notify you of the FP on your sig when it is reported to us at the same time we are notified, so that the signature can be fixed.
This process is ongoing but if you are interested in being added to the list of those already contributing or have additional questions, please contact me at bcouncil@cisco.com.
Your comments and concerns are also welcome.

Today I came across this older blog post (almost 10 years old at this point!) about a simple method you can use to create your won Anti-Virus signatures with ClamAV.
The article has a nice walk through of how to dump an attachment out of an email, how to write a simple ndb signature to detect it, and how to deploy it. I thought this was fairly simple and well done, so I wanted to share.
If you are interested in creating your own detection, this article is worth checking out.
http://blog.adamsweet.org/?p=250
If you want to proceed a step further and submit those signatures back to us, we'll take a look as well, and if you submit the most in a month, we'll send you some nice swag!

As a reminder from our post back on May 20th, EOL for ClamAV 0.97 is tomorrow (June 1st). We'll be removing this version from our test bed and will no longer ensure that signatures work on that version.
If you are on a 0.97 version, please make sure you upgrade as soon as possible. The current version is available on ClamAV.net.
Thanks.

ClamAV Community,
This notice is to inform you that effective June 1, 2016, ClamAV 0.97 (and all minor versions) is no longer supported in accordance with ClamAV's EOL policy which can be found here:
http://www.clamav.net/documents/end-of-life-policy-eol
EOL for ClamAV essentially means that we will no longer be testing against that version when we write signatures, and we may break something with a future release. So, while signatures may work past June 1st, we are no longer testing that configuration, so you are on your own.
Please upgrade to the newest version of ClamAV, currently at 0.99.2, available for download.
Thank you for using ClamAV!

A Brief History
With the release of ClamAV 0.99, users saw a slew of new features aimed at enhancing ClamAV’s core functionalities. Included in these features were the improvements to ClamAV’s long-neglected on-access scanning capabilities. Ages ago, ClamAV supported on-access scanning via the now-defunct Dazuko kernel module. When development on Dazuko ended in 2011, the ClamAV team began searching for a suitable replacement. The team soon landed on the recently stable fanotify API that first shipped with the 2.6.37 Linux kernel. By November of 2011 a barebones fanotify-based on-access scanner had been completed, but it wouldn’t see public release until ClamAV 0.98.
Fast forward to ClamAV version 0.99—four years after the creation of that first prototype—and users found themselves presented with a completely reworked on-access scanning system that now leveraged not only fanotify, but inotify as well. While ClamAV’s documentation had been updated to help navigate users through the transition, a number of people reported problems they were having with ClamAV’s on-access scanner. Almost invariably, these issues came down to either improper configuration or system-level limitations. This guide seeks to provide users interested in ClamAV’s on-access scanning with a definitive resource on the topic—straight from the horse’s mouth, so to speak.
System Requirements
fanotify
On-access scanning, requires a system running a Linux kernel (version >= 3.8) with fanotify compiled in. Check the kernel configuration for fanotify’s presence by running:
$ cat /boot/config-<kernel_version> | grep FANOTIFY
Results if fanotify is available:
CONFIG_FANOTIFY=y
Results if fanotify can prevent malicious file access attempts:
CONFIG_FANOTIFY_ACCESS_PERMISSIONS=y
If this is seen:
CONFIG_FANOTIFY=y
# CONFIG_FANOTIFY_ACCESS_PERMISSIONS is not set
# CONFIG_FANOTIFY_ACCESS_PERMISSIONS is not set
Then on-access scanning will be constrained to notify-only mode and will be unable to prevent access to malicious files, since fanotify lacks the ability to block events on the system.
inotify
To use the dynamic directory determination (DDD) system introduced in 0.99, ensure inotify is configured with enough watchpoints. By default, inotify can watch for changes in 8192 directories at any one time. If more directories than that need protection, run the following command—replacing <NUM> with the maximum number of directories to be watched:
$ echo <NUM> | sudo tee -a /proc/sys/fs/inotify/max_user_watches
Overview of Configuration Options
Overview of Configuration Options
The clamd.conf configuration file contains a number of options which modify the behaviour of ClamAV’s on-access scanner. Each configuration option is listed below alongside its intended purpose and any caveats of which users should remain cognizant.
ScanOnAccess
Purpose: Enables on-access scanning under clamd if set to “yes”. If set to ”no”, all other on-access configurations options will be ignored.
Caveats: clamd must be run as root.
Caveats: clamd must be run as root.
OnAccessMountPath
Purpose: Watches the entirety of one or more specified mount points and notifies the user of any malicious events caught by fanotify.
Caveats: Users must specify a valid mount point. If this option is enabled, clamd will disable fanotify prevention to keep users from accidentally locking up their system. Enabling this option will also disable the DDD system and all configuration options which rely on that system.
Caveats: Users must specify a valid mount point. If this option is enabled, clamd will disable fanotify prevention to keep users from accidentally locking up their system. Enabling this option will also disable the DDD system and all configuration options which rely on that system.
OnAccessMaxFileSize
Purpose: Allows the user to stop clamd from scanning files larger than the specified size. If set to “0”, clamd will scan all files regardless of size.
Caveats: On some kernel versions and architectures, fanotify is known to fail when blocking access to files larger than 4GB. ClamAV will alert users if this problem occurs.
Caveats: On some kernel versions and architectures, fanotify is known to fail when blocking access to files larger than 4GB. ClamAV will alert users if this problem occurs.
OnAccessIncludePath
Purpose: The files within the any specified path(s) will be monitored for access attempts. If the DDD system is enabled, clamd will watch this path recursively, i.e., the specified directory and all subdirectories will be monitored. If the DDD system is disabled, only the topmost directory will be watched and all subdirectories will be ignored.
Caveats: This option will be ignored if OnAccessMountPath is enabled. As an additional precaution, if DDD is enabled, clamd will prevent users from specifying “/” as an include path.
Caveats: This option will be ignored if OnAccessMountPath is enabled. As an additional precaution, if DDD is enabled, clamd will prevent users from specifying “/” as an include path.
OnAccessExcludePath
Purpose: Recursively removes the given directory from the set of directories monitored by clamd.
Caveats: If the DDD system is disabled, this option is ignored.
Caveats: If the DDD system is disabled, this option is ignored.
OnAccessExcludeUID
Purpose: When fanotify catches an event, clamd will check given UIDs against the captured pid. If a match is found, the event is ignored and no scanning is performed.
Caveats: There aren't any known caveats with this option.
Caveats: There aren't any known caveats with this option.
OnAccessDisableDDD
Purpose: This option allows users to turn off the DDD system if they prefer the legacy on-access scanning behaviour that was available in 0.98. If DDD is disabled OnAccessIncludePath will not recursively watch paths, making OnAccessExcludePath a redundant option.
Caveats: If OnAccessMountPath is enabled, clamd will act as though DDD is disabled.
Caveats: If OnAccessMountPath is enabled, clamd will act as though DDD is disabled.
OnAccessPrevention
Purpose: Flags fanotify to block any triggered events on monitored files, which allows ClamAV to scan affected files to determine if those events should be allowed to proceed.
Caveats: The kernel must be compiled with “CONFIG_FANOTIFY_ACCESS_PERMISSIONS=y” for this option to function. As a precaution, if OnAccessMountPath is enabled, clamd automatically disables this option to stop the user from accidentally locking up their system. Only access and open events can be blocked by fanotify.

As a precaution, if OnAccessMountPath is enabled, clamd automatically disables this option to stop the user from accidentally locking up their system. Only access and open events can be blocked by fanotify.
OnAccessExtraScanning
Purpose: Provides DDD users with inotify event coverage, which allows for scans on newly created, moved, or renamed files.
Caveats: Since this option relies on the inotify framework maintained by the DDD system, it is ignored if OnAccessDisableDDD is “yes”.

Configuration Examples
This guide ends with a few simple clamd.conf configuration examples which will satisfy a number of general use cases. Though there are only four, these examples can readily be expanded upon or adapted to fit more targeted use cases.
Watch entire filesystem
ScanOnAccess yes
OnAccessMountPath /
OnAccessExcludeUID 0
Details: This will set fanotify to watch the entire filesystem in real-time and trigger ClamAV to run scans on any files opened, accessed, or closed except by the root user. While clamd will report any viruses found during this scanning, fanotify will not perform any blocking or prevention.

Watching select users’ home directories
ScanOnAccess yes
OnAccessIncludePath /home
OnAccessExcludePath /home/user2
OnAccessExcludePath /home/user2
OnAccessExcludePath /home/user4
OnAccessExtraScanning yes
Details: Like the previous example, fanotify is not flagged to prevent events which occur on malicious files. However, further scanning coverage is provided thanks to OnAccessExtraScanning leveraging the inotify events caught by the DDD system.
OnAccessExtraScanning yes

Protecting a directory recursively
ScanOnAccess yes
OnAccessIncludePath /home/user/Downloads
OnAccessPrevention yes
OnAccessExtraScanning yes
Details: Here fanotify will block any triggered events, allowing only clean files to be opened, or otherwise accessed. This configuration will also immediately alert the user if a malicious file is inadvertently downloaded.

Protecting multiple dirs non-recursively
ScanOnAccess yes
OnAccessIncludePath /home/user/dir1
OnAccessIncludePath /home/user/dir2
OnAccessPrevention yes
OnAccessDisableDDD yes
Details: Similarly to legacy behaviour, only the top level of dir1 and dir2 will be protected in this case. The contents of all subdirectories will be ignored and extra scanning via inotify events is not possible since DDD is disabled.

Our ClamAV Signature Interface maintenance is now complete. While we apologize for the delay, the rollout of the the new Signature Interface inside of ClamAV will result in several new features for the community, and I wanted to tell you about some of them:
First, the first new “main.cvd” in about two years. This main.cvd has been completely re-written from scratch, and while the function of the “main” is largely the same, it’s been rewritten to not only enforce order to the signatures, but naming convention as well. For example:
W97M.Ethan.AK-1 has moved to Doc.Trojan.Ethan
Worm.Padowor.A-zippwd has moved to Win.Worm.Padowor
Adware.Smshoax has moved to Win.Adware.Smshoax
Re-naming of the signatures may affect a local user’s whitelist. If you have excluded certain signatures in the past that are now firing, we ask that you both submit the file to us for false positive remediation (if you believe it to be a false positive), and rename the signature whitelist on your side.
This new main is 109Mb in size, and contains 4 million signatures for ClamAV. Now that the main.cvd has been rewritten, it is now easier for us to create diffs, which means upgrading the main more often, and making the “daily.cvd” smaller more often.
Second, we now have the ability to offer different types of CVDs. For instance, we now have the ability to distribute 3rd party signatures that are officially signed by ClamAV, but updated through the ClamAV global mirror network. If we wanted to separate out “policy” type signatures from the daily.cvd into their own cvd, we can now do that.
Third, while we have not removed some of the older signature formats, we did convert those older signatures to the newer formats to empty those older “cvd”s out.
For example:
“db" signatures were consolidated into “ndb" signatures
“zmd" and “rmd" archive signatures we moved to the “cdb" container signature format
These formats are not new, they simply have never been published before. This includes other formats such as “hsb", “msb", “sfp", and “crb". The older formats are supported for now, we are simply no longer publishing them.
Fourth, newer features, like the ability to write signatures based on the SHA256 of a file have been added to the system, and we can now publish that type of detection.
We’d like to thank you for your patience.

ClamAV added support for a new family, or perhaps old family of documents, in the 0.99.1 release: Hangul Word Processor (HWP) documents. HWP documents are document files specialized in the Korean language and developed by Hancom Inc.. The documents’ specialization in Korean make it a highly popular format used in South Korea with the government being a notable example. As popular format, it is subjected to possibly malicious content.
For this release, we primarily targeted the word-specific documents: HWP 2.x, HWP 3.x, HWP 5.x, and HWPX. The other file formats developed by Hancom Inc. which cover the spreadsheet and presentation formats are already handled by pre-existing methods in ClamAV; the only exception is HPT (an old presentation format) which will not be in this release.
- HWP 2.x, also known as HWPML
- XML-based document format similar to Microsoft’s older XML document format
- Contents of the document is stored in the XML including all embedded content
- Embedded content is usually base64-encoded and normally uses zlib compression
- General embedded content is stored in OLE2 containers
- File property collection: document’s attributes and metadata fields
- HWP 3.x, also known as HWP
- Custom binary file format. For additional information on the format, the documentation can be retrieved from Hancom’s website (note that it’s in Korean)
- Contents of HWP 3.x are stored in a file segment that uses optional password encryption and normally uses zlib compression
- Embedded content is stored in the content stream with general embedded content stored in HWP-styled* OLE2 containers
- File property collection: data from various file headers
- HWP 5.x, also known as HWP
- OLE2-based document format similar to Microsoft’s 97-2003 document formats
- Contents of HWP 5.x are stored in individual streams with zlib compression normally used on specific content streams including embedded content
- Embedded content is stored in individual streams under the BinData directory with general embedded content stored as HWP-style* OLE2 containers
- File property collection: data from the fileheader stream which appears to be the HWP legacy header and the /x005HwpSummaryInformation stream which uses the same property method as 97-2003 Microsoft documents
- HWPX
- OOXML-compliant document format
- Contents of the document are stored in XML documents within a ZIP archive
- Embedded content is stored in the BinData directory with general embedded content stored as HWP-style* OLE2 containers
- File property collection: data from the content.hpf document which is an xml document with the legacy file header.
*Hwp-styled OLE2 container are identical to normal OLE2 container with the exception that a 32-bit value is prepended to file/stream/data segment

As we periodically do, we will be releasing a new main.cvd and daily.cvd this coming weekend (March 12-13).
We have completely re-written our signature management interface internally here at ClamAV, to provide us with more features and a better management process for cvd releases. Part of the process will be to create these two new files.
Releasing these files will have an impact, not only to the end user who will have to download these files, but also to our dedicated mirror operators that will be serving these files to the end users.
The estimated size of these files are 100 MB and 10 MB respectively.
Please be ready to receive these files this weekend. It is our hope that everything goes smoothly and, other than bandwidth, users shouldn't experience any problems. For any questions, please do not hesitate to contact us.
