Tricky Windows worm poses as game

Bibrog-B con


A new email-aware worm, Bibrog-B, poses as a computer game in an attempt to dupe users.

The worm, which is spreading (modestly) by email and through file sharing networks, is more subtle and devious than most Windows worms. Its payload contains not just malicious code but a shooting game too.

When users infect themselves via a virus they might notice something is wrong with their PC. The game component of Bibrog-B masks its true purposes.

While the shooting game is running, the worm is copying itself across the user's hard drive and preparing to forward itself to all contacts in the Outlook address book, or via file-sharing networks.

In a particularly devious twist the worm makes changes to an infected user's Internet browser so that it can display fake versions of genuine Web sites such as Hotmail, Citibank, MSN and Yahoo. Security firms believe this is an attempt to steal usernames and passwords.

"Many people assume a virus that destroys data is as bad as it gets. However, a virus which can swipe confidential details such as account information is a much greater potential danger," said Graham Cluley, senior technology consultant for Sophos Anti-Virus.

More details of the Bibrog worm are available here.

The payload of the worm comes in the form of an executable attachment. Blocking such attachments in email, which have little or no legitimate use, is probably the simplest and most effective way to guard against Bibrog and other similar viruses. ®

  • Despite global uncertainty, $500m hit doesn't rattle Nvidia execs
    CEO acknowledges impact of war, pandemic but says fundamentals ‘are really good’

    Nvidia is expecting a $500 million hit to its global datacenter and consumer business in the second quarter due to COVID lockdowns in China and Russia's invasion of Ukraine. Despite those and other macroeconomic concerns, executives are still optimistic about future prospects.

    "The full impact and duration of the war in Ukraine and COVID lockdowns in China is difficult to predict. However, the impact of our technology and our market opportunities remain unchanged," said Jensen Huang, Nvidia's CEO and co-founder, during the company's first-quarter earnings call.

    Those two statements might sound a little contradictory, including to some investors, particularly following the stock selloff yesterday after concerns over Russia and China prompted Nvidia to issue lower-than-expected guidance for second-quarter revenue.

  • Another AI supercomputer from HPE: Champollion lands in France
    That's the second in a week following similar system in Munich also aimed at researchers

    HPE is lifting the lid on a new AI supercomputer – the second this week – aimed at building and training larger machine learning models to underpin research.

    Based at HPE's Center of Excellence in Grenoble, France, the new supercomputer is to be named Champollion after the French scholar who made advances in deciphering Egyptian hieroglyphs in the 19th century. It was built in partnership with Nvidia using AMD-based Apollo computer nodes fitted with Nvidia's A100 GPUs.

    Champollion brings together HPC and purpose-built AI technologies to train machine learning models at scale and unlock results faster, HPE said. HPE already provides HPC and AI resources from its Grenoble facilities for customers, and the broader research community to access, and said it plans to provide access to Champollion for scientists and engineers globally to accelerate testing of their AI models and research.
