The easiest and most effective action you can take to protect yourself from worms is to get a total antivirus protection plan. Avoid opening unfamiliar messages and attachmentsĪnd don't forget to get good antivirus protection such as Panda DOME.
I WORM VIRUS SERIES
There are a series of basic measures you can take to ensure your devices are protected against worms:
I WORM VIRUS DOWNLOAD
Like us, they unknowingly download and open the attached file, thus getting infected. We distribute computer viruses by sending infected attachments to other users. Most of these names relate to sex, famous people, or pirated software. To do so, malware creators use attractive names to camouflage their malicious files. Worms often use social engineering techniques. They do this by creating copies of themselves on infected computers, which then spread to other computers via different channels including email, P2P programs, etc.
I WORM VIRUS CODE
While a virus is malicious code that replicates itself following human intervention, a worm is a type of malware that can replicate itself and spread from system to system without human interaction or intervention. The main objective of worms is to spread and infect as many computers as possible. ILOVEYOU is also known as the 'love letter virus' and the 'love bug worm.' Although commonly referred to as a computer virus, ILOVEYOU is actually a worm. Unlike viruses, worms don't infect files. The objective of this type of malware is usually to saturate computers and networks, preventing them from being used. Worms are programs that make copies of themselves in different places on a computer. "By the time a traditional cure is ready, a large fraction of susceptible machines could be compromised by such a flash threat.Worms are actually a subclass of virus, so they share characteristics. Responses to a computer virus/worm typically "take hours and require companies to capture and analyze a threat in the lab, produce a fingerprint, and distribute the fingerprint to millions of users," he says. "This research clearly indicates that a fundamentally new security approach is required," says Carey Nachenberg, a senior security analyst at Symantec Research Labs in Cupertino, California. However, Moore says a more sinister worm carrying up to 1500 bytes-enough space to add data-erasing instructions or other nasty commands-would have been nearly as fast.
I WORM VIRUS WINDOWS
Because Sapphire did not have a malicious payload attached to it, it wreaked havoc merely by flooding networks with bogus traffic. The Kak virus/worm uses ActiveX, VBScript and Windows Script Host as vehicles to exploit the vulnerabilities of.
I WORM VIRUS PATCH
The outbreak died down after about 24 hours as network administrators applied a software patch from Microsoft. By comparison, the Code Red worm only sent six copies of itself every second. For instance, an infected desktop computer with a typical DSL connection could deal out roughly 300 copies per second of the worm a faster university or corporate server could send copies up to 100 times faster. By exploiting a quirk in Microsoft's SQL database management servers (and a desktop equivalent), Sapphire rapidly sent itself to potential victims. Such brevity allowed Sapphire to fit into network packets, the blocks of data computer systems swap online.
Sapphire's instructions were only 376 bytes long, about the length of this paragraph. The secret of the worm's success was its tiny size. "It grew so fast it actually interfered with its further growth, because it clogged up the available bandwidth," says study co-author David Moore at the San Diego Supercomputer Center. Within 10 minutes, Sapphire infected more than 90% of vulnerable hosts. In a technical paper published online yesterday, investigators report that during the first explosive minutes of Sapphire's attack, the worm doubled its numbers every 8.5 seconds, more than 250 times speedier than the Code Red worm that attacked the Internet in July 2001 (see comparison). Within an hour after its release, Nimda reached the top spot of all reported attacks. But it’s actually a computer virus known as Nimda (admin spelled backwards) that hit the internet back in 2001. Pacific time on 24 January and spread to more than 75,000 computers around the globe in a few minutes, knocking out 911 emergency services, automated teller machines, and airline online ticketing systems as well as denying Internet access to millions. A worm, a virus, and a Trojan horse all in one sounds like something out of a horror movie. Sapphire, also called Slammer, debuted at 9:30 p.m. It represented some scary malware firsts and is likely a harbinger of worms to come. Unlike computer viruses, which embed themselves in programs and can't spread without help, worms use computer networks to propagate. The Sapphire worm that struck the Internet 2 weeks ago was the fastest spreading computer infection in history, according to a new technical report, whose authors call this latest infection a milestone in worm evolution.
