Preface

Anti-virus protection as information security

“Theworld changed [onMarch26,1999]—does anyonedoubtthat?The world

is different. Melissa proved that ... and we are very fortunate ... the world

could have gone very close to meltdown.”

—Padgett Peterson, Chief Info Security Architect, Lockheed Martin Corporation,

on the 1999 “Melissa” virus epidemic

Bytheendofthe1990s,manyinformationtechnologyprofessionalshad

begun to recognize that they could not easily separate how they needed to

respond to new virus threats from how they already dealt with deliberate

network security breaches. Dorothy Denning, co-editor of the 1998 computer

security handbook Internet Besieged: Countering Cyberspace Scofflaws, explicitly

grouped anti-virus security measures in with other network security

measures, classifying them as a defense against malicious “injected code.”

Denning justified her inclusive grouping on based on her definition of

information security as “the effective use of safeguards to protect the

confidentiality, integrity, authenticity, availability, and non-repudiation of

information and information processing systems.” Virus payloads had always

threatened or damaged data integrity, but by the time she wrote her survey

article, newer viruses had already begun to mount sophisticated attacks that

struck at the remaining underpinnings of information security. Denning’s

classification recognized that newer viruses no longer merely annoyed system

administrators or posed a relatively low-grade threat; they had in fact

graduated to become a serious hazard.

Though not targeted with as much precision as an unauthorized network

intrusion, virus attacks had begun to take on the color of deliberate

information warfare. Consider these examples, many of which introduced

quickly-copied innovations to the virus writer’s repertoire:

• W32/CIH.Spacefiller destroyed the flash BIOS in workstations it infected,

effectively preventing them from booting. It also overwrote parts of the

infected hard disk with garbage data.

• XM/Compat.Arewrotethe datainsideMicrosoftExcelspreadsheetfiles.It

used advanced polymorphic concealment techniques, which meant that

with each infection it changed the signature bytes that indicated its

presence and allowed anti-virus scanners to find it.

Preface

xii Dr Solomon’sAnti-Virus

• W32/Ska, though technically a worm, replaced the infected computer’s

WinSock file so that it could attach itself to outgoing Simple Mail Transfer

Protocol (SMTP) messages and postings to USENET news groups. This

strategy made it commonplace in many areas.

• Remote Explorer stole the security privileges of a Windows NT domain

administrator and used them to install itself as a Windows NT Service. It

also deposited copies of itself in the Windows NT driver directory and

carried with it a supporting Dynamic Link Library (.DLL) file that allowed

it to randomly encrypt data files. Because it appeared almost exclusively at

one corporate site, security experts speculated that it was a deliberate,

targeted attack on the unfortunate company’s network integrity.

• Back Orifice, the product of a group calling itself the Cult of the Dead Cow,

purported to give the owner of the client portion of the Back Orifice

application complete remote access to any Windows 95 or Windows 98

workstation that runs the concealed companion server. That access—from

anywhere on the Internet—allowed the client to capture keystrokes; open,

copy, delete, or run files; transmit screen captures; and restart, crash, or

shut down the infected computer. To add insult to injury, early Back

Orifice releases on CD-ROM carried a W32/CIH.Spacefiller infection.

Throughout much of 1999, virus and worm attacks suddenly stepped up in

intensity and in the public eye. Part of the reason for this, of course, is that

many of the more notorious viruses and worms took full advantage of the

Internet, beginning a long-predicted assault by flooding e-mail transmissions,

websites, newsgroups and other available channels at an almost exponential

rate of growth. They now bullied their way into network environments,

spreading quickly and leaving a costly trail of havoc behind them.

W97M/Melissa, the “Melissa” virus, jolted most corporate information

technology departments out of whatever remaining complacency they had

held onto in the face of the newer virus strains. Melissa brought corporate

e-mail servers down across the United States and elsewhere when it struck in

March 1999. Melissa instructed e-mail client programs to send out infected

e-mail messages to the first 50 entries in each target computer’s address book.

This transformed a simple macro virus infection with no real payload into an

effective denial-of-service attack on mail servers.

Melissa’s other principle innovation was its direct attempt to play on end-user

psychology: it forged an e-mail message from a sender the recipient knew, and

sent it with a subject line that urged that recipient to open both the message

and the attached file. In this way, Melissa almost made the need for viral code

to spread itself obsolete—end users themselves cooperated in its propagation,

and their own computers blindly participated.

Administrator’s Guide xiii

Preface

A rash of Melissa variants and copycats appeared soon after. Some, such as

W97M/Prilissa, included destructive payloads. Later the same year, a number

of new viruses and worms either demonstrated novel or unexpected ways to

get into networks and compromise information security, or actually

perpetuated attacks. Examples included:

• W32/ExploreZip.worm and its variants, which used some of Melissa’s

techniques to spread, initially through e-mail. After it successfully infected

a host machine, ExploreZip searched for unsecured network shares and

quietly copied itself throughout a network. It carried a destructive payload

that erased various Windows system filesand Microsoft Office documents,

replacing them with an unrecoverable zero-byte-length files.

• W32/Pretty.worm, which did Melissa one better by sending itself to every

entry in the infected computer’s MAPI address book. It also connected to

an Internet Relay Chat (IRC) server, joined a particular IRC channel, then

opened a path to receive commands via the IRC connection. This

potentially allowed those on the channel to siphon information from the

infectedcomputer, includingthe computername and owner’s name,hisor

her dial-up networking user name and password, and the path to the

system root directory.

• W32/FunLove.4099, which infected ActiveX .OCX files, among others.

This meant that it could lurk on webpages with ActiveX content, and infect

systems with low or nonexistent browser security settings as they

downloaded pages to their hard disks. If a Windows NT computer user

had logged into a system with administrative rights, the infecting virus

would patch two critical system files that gave all users on the network

—including the virus—administrative rights to all files on the target

computer. It spread further within the network by attaching itself to files

with the extensions .SCR, .OCX, and .EXE.

• VBS/Bubbleboy, a proof-of-concept demonstration that showed that a

virus could infect target computers directly from e-mail messages

themselves, without needing to propagate through message attachments.

It effectively circumvented desktop anti-virus protection altogether, at

least initially. Its combination of HTML and VBScript exploited existing

vulnerabilitiesinInternet-enabledmail systems;itsauthorplayedupon the

same end-user psychology that made Melissa successful.

The other remarkable development in the year was the degree to which virus

writers copied, fused, and extended each others’ techniques. This cross-

pollination had always occurred previously, but the speed at which it took

placeandtheincreasingsophisticationof thetoolsandtechniquesthatbecame

available during this period prepared very fertile ground for a nervously

awaited bumper crop of intricate viruses.

Preface

xiv Dr Solomon’sAnti-Virus

Information security as a business necessity

Coincidentally or not, these darkly inventive new virus attacks and speedy

propagation methods appeared as more businesses made the transition to

Internet-based information systems and electronic commerce operations. The

convenience and efficiency that the Internet brought to business saved money

and increased profits. This probably also made these same businesses

attractive targets for pranksters, the hacker underground, and those intent on

striking at their favored targets.

Previously, the chief costs from a virus attack were the time and money it took

to combat an infection and restore computer systems to working order. To

those costs the new types of virus attacks now added the costs of lost

productivity, network and server downtime, service denials for e-mail and

other critical business tools, exposure—and perhaps widespread distribution

—of confidential information, and other ills.

Ultimately, the qualifying differences between a hacker-directed security

breach in a network and a security breach that results from a virus attack

might become merely ones of intent and method, not results. Already new

attacks have shaken the foundations of Net-enabled businesses, many of

which require 24-hour availability for networks and e-mail, high data

integrity, confidential customer lists, secure credit card data and purchase

verification, reliable communications, and hundreds of other computer-aided

transactional details. The costs from these virus attacks in the digital economy

now cut directly into the bottom line.

Because they do, protecting that bottom line means implementing a total

solution for information and network security—one that includes

comprehensive anti-virus protection. It’s not enough to rely only on

desktop-basedanti-virusprotection,oronhaphazardoradhocsecurity

measures. The best defense requires sealing all potential points by which

viruses can enter or attack your network, from the firewall and gateway down

to the individual workstation, and keeping the anti-virus sentries at those

points updated and current.

Part of the solution is deploying the Dr Solomon’s Active Virus Defense*

software suite, which provides a comprehensive, multi-platform series of

defensive perimeters for your network. You can also build on that security

with the Dr Solomon’s Active Security suite, which allows you to monitor

your network against intrusions, watch actual network packet traffic, and

encrypt e-mail and network transmissions. But even with anti-virus and

security software installed, new and previously unidentified viruses will

inevitably find their way into your network. That’s where the other part of the

equation comes in: a thorough, easy-to-follow anti-virus security policy and

set of practices for your enterprise—in the last analysis, only that can help to

stop a virus attack before it becomes a virus epidemic.

Administrator’s Guide xv

Preface

Active Virus Defense security perimeters

The Dr Solomon’s Active Virus Defense product suite exists for one simple

reason: there is no such thing as too much anti-virus protection for the

modern, automated enterprise. Although at first glance it might seem

needlessly redundant to protect all of your desktop computers, file and

network servers, gateways,e-mail servers and firewalls, each of these network

nodesservesadifferentfunctionin yournetwork,andhas different duties.An

anti-virus scanner designed to keep a production workstation virus-free, for

example, can’t intercept viruses that flood e-mail servers and effectively deny

their services. Nor would you want to make a file server responsible for

continuously scanning itsclient workstations—the cost in network bandwidth

would be too high.

More to the point, each node’s specialized functions mean that viruses infect

them in different ways that, in turn, call for optimized anti-virus solutions.

Viruses and other malicious code can enter your network from a variety of

sources—floppy disks and CD-ROMs, e-mail attachments, downloaded files,

and Internet sites, for example. These unpredictable points of entry mean that

infecting agents can slip through the chinks in incomplete anti-virus armor.

Desktop workstations, for example, can spread viruses by any of a variety of

means—via floppy disks, by downloading them from the Internet, by

mapping server shares or other workstations’ hard disks. E-mail servers, by

contrast, rarely use floppy disks and tend not to use mapped drives—the

Melissa virus showed, however, that they arequite vulnerable to e-mail–borne

infections, even if they don’t execute the virus code themselves.

At the desktop: Dr Solomon’sAnti-Virus

The Dr Solomon’s Active Virus Defense product suite matches each point of

vulnerability with a specialized, and optimized, anti-virus application. At the

desktop level, the cornerstone of the suite is the Dr Solomon’s Anti-Virus

anti-virus product. Dr Solomon’s Anti-Virus protects some of your most

vulnerable virusentry points withan interlocking set ofscanners, utilities, and

support files that allow it to cover:

• Localharddisks,floppydisks,CD-ROMs,andotherremovablemedia.The

WinGuard scanner resides in memory, waiting for local file access of any

sort. As soon as one of your network users opens, runs, copies, saves,

renames, or sets attributes for any file on their system—even from mapped

network drives—the WinGuard scanner examines it for infections.

You can supplement this continuous protection with scan operations you

configure and schedule for your own needs. Comprehensive security

options let you protect individual options with a password, or run the

entire application in secure mode to lock out all unauthorized access.

Preface

xvi Dr Solomon’sAnti-Virus

• System memory, boot sectors, and master boot records. You can configure

regularly scheduled scan operations that examine these favorite virus

hideouts, or set up periodic operations whenever a threat seems likely.

• Microsoft Exchange mailboxes. Dr Solomon’s Anti-Virus includes a

specialized E-Mail Scan extension that assumes your network user’s

Microsoft Exchange or Outlook identity to scan his or her mailbox

directly—before viruses get downloaded to the local workstation. This can

prevent some Melissa-style infections and avoid infections from the next

generation of VBS/Bubbleboy descendants.

• Internet mail and file downloads. The WinGuard scanner includes two

modules that specialize in intercepting SMTP and POP-3 e-mail messages,

and that can examine files your network users download from Internet

sites. The E-Mail Scan and Download Scan modules work together to scan

the stream of file traffic that most workstations generate and receive daily.

• Hostile code. The Olympus scan engine at the heart of Dr Solomon’s

Anti-Virus routinely looks for suspicious script code, macro code, known

Trojan horse programs—even virus jokes or hoaxes. With the help of the

WinGuard Internet Filter module, it also blocks hostile ActiveX and Java

objects, many of which can lurk unnoticed on websites, waiting to deploy

sophisticated virus-like payloads. The Internet Filter module can even

block entire websites, preventing network users from visiting sites that

pose a threat to network integrity.

Dr Solomon’s Anti-Virus ties these powerful scanning capabilities together

with a powerful set of alerting, updating, and management tools. These

include:

• Alert Manager client configuration. Dr Solomon’s Anti-Virus includes a

client configuration utility you can use to have it pass alert messages

directly to Alert Manager servers on your network, to a Centralized

Alerting share, or to a Desktop Management Interface administrative

application. Other alert methods include local custom messages and beeps,

detection alerts and response options, and e-mail alert messages.

• Next-generation AutoUpdateandAutoUpgradeutilities.AutoUpdate v4.5

features complete and transparent support for new incremental .DAT file

updates, which save you time and network bandwidth by adding only

virus definitions you don’t already have installed on your system. The new

AutoUpgrade version includes support for v1.2 of the Dr Solomon’s

SuperDAT utility, which you can use to update the Olympus scan engine

and its support files.

Preface

• Integration with DrSolomon’sePolicy Orchestrator management software.

Centralized anti-virus management takes a quantum leap forward with

this highly scalable management tool. Dr Solomon’s Anti-Virus ships with

a plug-in library file that works with the ePolicy Orchestrator server to

enforce enterprise-wide network security policies.

You can use ePolicy Orchestrator to configure, update, distribute and

manage Dr Solomon’s Anti-Virus installations at the group, workstation or

user level. Schedule and run scan tasks, change configurations, update

.DAT and engine files—all from a central console.

Taken together, the ActiveVirus Defense suite forms a tightseriesofanti-virus

security perimeters around your network that protect you against both

external and internal sources of infection. Those perimeters, correctly

configured and implemented in conjunction with a clear enterprise-wide

anti-virus security policy, do indeed offer useful redundancy, but their chief

benefit lies in their ability to stop viruses as they enter your network, without

your having to await a tardy or accidental discovery. Early detection contains

infections, saves on the costs of virus eradication, and in many cases can

prevent a destructive virus payload from triggering.

Dr Solomon’s anti-virus research

Even the best anti-virus software is only as good as its latest update. Because

as many as 200 to 300 viruses and variants appear each month, the .DAT files

that enable Dr Solomon’s software to detect and remove viruses can get

quickly outdated. If you have not updated the files that originally came with

your software, you could risk infection from newly emerging viruses. Dr

Solomon’s has, however, assembled the world’s largest and most experienced

anti-virus research staff in its Anti-Virus Emergency Response Team

(AVERT)*. This premier anti-virus research organization has a worldwide

reach and a “follow the sun” coverage policy, that ensures that you get the files

you need to combat new viruses as soon as—and often before—you need

them. You can take advantage of many of the direct products of this research

by visiting the AVERT research site on the Network Associates website:
