Experts gather for cybercrime conference

Internet security experts are gathering at a secretive conference later this week to form strategies in their fight against cybercriminals.

The meeting on Thursday and Friday at Microsoft's Redmond, Washington headquarters is slated to bring together representatives from security companies and government and law-enforcement officials, as well as others involved in network security. The agenda focuses on botnets and related topics, seen by experts as a prime threat to the internet.

"Unlike most other security conferences, we allow only members of the different relevant groups access, and we discuss organised crime and threats across borders… with a strong lean towards how we can make things better," said Gadi Evron, an evangelist at security firm Beyond Security and organiser of the event.

Botnets are networks of hijacked computers, popularly called zombies. Cybercrooks use these networks to relay spam, bring down websites, distribute spyware and perform other nefarious acts. Microsoft has fingered zombies as a top threat to Windows PCs.

In the battle between cybercrooks and those protecting the internet, the bad guys are often at least one step ahead. Authorities are cracking down and have had successes in catching, prosecuting and convicting phishers and bot herders in recent years. But criminals are organising better and moving to more sophisticated tactics, including the use of peer-to-peer technologies in their bot software. The gathering this week is the good guys' effort to team up.

"These events have been a great way to build trust in the security community, which can lead to collaboration and data sharing. This helps in the overall efforts to combat the cybercriminals," said Dave Jevans, chairman of the Anti-Phishing Working Group, who is slated to speak at the event later this week.

The two-day meeting is held behind closed doors. "For reasons of practicality as well as to help members feel safe to share and work in our environment, some privacy is required," Evron said. "Not everything can be common knowledge if we are to be successful in combating these threats."

It is not unusual for such meetings to be confidential. After all, it doesn't make much sense to let the criminals in on the efforts being made to catch them. Also, this isn't a new thing for Microsoft — the company regularly holds meetings at its campus that require a nondisclosure agreement.

Scheduled presentations at this week's event include two talks by Microsoft on security vulnerabilities that have no patch, known as zero-day flaws, and the software maker's response to those. There has been a significant rise in the use of zero-day bugs in cyberattacks. Criminals often exploit security holes to add PCs to their botnets.

"Microsoft will be presenting our analysis of trends and patterns in its security response process," a company representative said. "Additionally, we will be reviewing vulnerability exploitation trends, with a specific focus on the usage of zero-day vulnerabilities, to attack customers."

Microsoft also said it is "proud to sponsor the workshop, which provides an opportunity for the security operations community to discuss security trends, share information and plan for the future".

Trojan horses, phishing and spam — oh my Aside from various talks specifically on botnets, other presentations dive into Trojan horses, new styles of denial-of-service attacks, spam, phishing and weaknesses in protection technologies such as sandboxes and virtual keyboards on banking sites, according to the event agenda.

Douglas Otis of Trend Micro plans to give a talk on how email authentication technology called Sender ID could be abused to launch denial-of-service attacks, he said. Sender ID is a specification pushed heavily by Microsoft for verifying the authenticity of email by ensuring the validity of the server from which it came.

Jevans of the Anti-Phishing Working Group plans to present a multiyear overview of phishing statistics and discuss new trends in the data-thieving scams, he said. These new trends include use of subdomains, more man-in-the-middle style attacks and changing attack patterns to focus on smaller banks and payment services, he said.

Alex Shipp, a senior antivirus technologist at email security company MessageLabs, is scheduled to deliver a talk on Trojan horses targeted at a small number of companies or even individuals. It is an update to a presentation he gave at the Virus Bulletin conference last year. These targeted Trojan horse attacks are considered dangerous because they could evade traditional protection mechanisms trained to look for known attacks or mass attacks.

But Shipp also hopes to leave with answers to a number of questions. Ultimately, the event should better arm attendees in the fight against cyberattacks, he said.

Some of those questions, according to Shipp, are: "What are the bad guys doing now and how can we stop them? Can we do better than we are currently or do we need a seismic shift in the way we do things now to solve the problems? What kind of co-operative efforts can we put in place that would benefit us all?"

Among those scheduled to attend are representatives from security firms such as Symantec, Trend Micro and Websense, as well as people from AOL, Cisco, Microsoft, Sun and Qwest. Government and law enforcement expected to attend include the Federal Bureau of Investigation, Secret Service and United States Computer Emergency Readiness Team, or US-CERT. Various universities are also expected to send representatives.

"Co-operation at all levels, technical, legal, government, is needed to contain the problem," said Righard Zwienenberg, chief research officer at Norman Data Defense Systems, who is slated to speak on sandboxes at the event on Thursday. "Without worldwide laws and co-operation, we might lose the battle in the end."
