However, the worm and virus attacks have declined from their heyday when the MSBlast, or Blaster, worm infected more than 25 million PCs. Instead, bot networks and targeted Trojan horses--which some industry media professionals have labeled 'spear phishing'--have become more of a threat.
Two major arrests of bot masters or bot herders--the people who control bot networks--have shed more light on the threat of compromised PCs. In October, Dutch prosecutors revealed that they had arrested three men responsible for compromising and controlling more than 1.5 million PCs. In November, U.S. federal authorities charged a 20-year-old California man with profiting from his control of some 400,000 PCs. While many security experts doubted that the arrests would significantly curtail the expansion and trade in bot nets, some have pointed to such arrests as one reason why worms have become less common since the Sasser epidemic.
While bots are a widespread threat, the more silent threat of singular attacks on companies and government organizations is less well understood. Attackers have focused on creating technology to keep attack tools stealthy, and rather than creating worms that propagate wildly, have instead targeted specific individuals within companies and government agencies. The attacks are being investigated by the U.S. under the name 'Titan Rain,' according to a September article in Time Magazine.
The vulnerability disclosure debate resurfaced in 2005, as some researchers became less enamored of the way software companies were responding to flaw reports.
When researchers from the U.K. planned to reveal details of flaws in products from database maker Sybase, the company responded with legal threats, which it dropped in April after negotiations. The incident that gained the most attention was Michael Lynn's disclosure of Cisco vulnerabilities at the annual Black Hat conference in July. The researcher for Internet Security Systems resigned from the company so he could present details of security flaws in Cisco's routers. The companies then filed suit against the researcher, but settled a day later. The incident has riled up security researchers, however, with some groups committing themselves to reproducing Lynn's research.
The debate is far from finished, however. A recent auction of a previously unknown flaw in Microsoft Excel on eBay, reignited the debate over what constitutes responsible disclosure. eBay shuttered the seller's attempt to auction the flaw.
The year also left the future of digital-rights management somewhat in doubt as well.
In October, security researchers revealed that media giant Sony BMG had been using poorly designed software that resembled surreptitious software commonly employed by online attackers to enforce copy protections. The software hid itself from users, could not easily be uninstalled, and had major security flaws that compromised the security of consumers' PCs. Digital-rights advocates took the media giant to task, and law firms filed more than 20 lawsuits, including a government action filed by the Attorney General for the State of Texas.
A proposed settlement for six cases filed in the Southern District of New York would prevent Sony BMG from distributing copy protected CDs for two years.
