Further information from the London "Independent" newspaper 15 Dec bylined by Science Editor Tom Wilkie, titled 'Trojan' threatens 10,000 computers: Fears are growing that more than one mailing list was used todistribute the "Aids Information" computer diskette which is damaging computers. Police said yesterday that they had been "inundated" by thousands of complaints about the disk, which they believe may have been distributed to more than 10,000 addresses in Britain. There are also unconfirmed reports tha delegates to an Aids conference in Sweden have been sent copies of the diskette from London. Experts estimate that the cost of the operation must run to between 8,000 and 10,000 pounds. .. According to Dr Alan Solomon, a leading expert on computer security, the program counts the times a user switches on the machine. After about 90 startups, Dr Solomons said, the damage routine is triggered. The program encrypts the names of all files held on the hard disks and "hides" them. This means that the computer's normal operating software is unable to find anything except one file, "CYBORG.DOC" which contains a demand for payment. According to Steve Robinson of the software company Insoft, the damage routine may be triggered on some machines almost as soon as the program is run. ... >In addition, the British magazine "PC Business World" has >included a copy of the diskette with its most recent publication (I do not confirm the truth of this assertion, but the article continues) PC Business World has produced an "Aidsout" program, written by virus hunter Jim Bates, on a disk which the magazine will distribute free to victims. The program is also available on "Connect" the IBM PC User Group bulletin board. .. (various other symptoms) Experts agree the program is so big and cleverly written that it will take months to tease out all the things it may do. For that reason, users should remove all trace from machines as soon as possible.
