CERT/CC announced many vulnerabilities in SNMPv1 on 12th February. SMNP is used in many systems for management and control, and a large number of implementations, from many vendors, have similar flaws. Currently, there do not seem to be attackers exploiting these, but that is just a matter of time. Sites that use SNMP should check the advisory
W32/Yarner started spreading rapidly on 19th February, but it was quickly apparent that it would have minimum effect outside Germany. The virus arrives in an email that appears to be from a Trojan information website. The German message explains that it is a new version of a utility that provides warnings if a premium-rate phone number is dialled. Of course, if it is run, it provides no benefit, but emails itself to many addresses, and it may also delete files from the hard disk. No incidents have been reported in Hong Kong.
