McAfee, Symantec and Trend Micro are reportedly the anti-virus companies whose source code the cybercriminal group Fxmsp claims to have stolen. Comments issued by the vendors minimized the threat, although Trend Micro did confirm that a breach had occurred.

Last week cybersecurity firm Advanced Intelligence (AdvIntel) reported in a company blog post that Fxmsp was offering to sell the AV firms' code for as much as $300,000 via its dark web reseller network. AdvIntel Director of Security Research Yelisey Boguslavskiy told SC Media that the hacking collective had vaguely alluded to a fourth victimized company, but never mentioned it by name.

For security reasons, AdvIntel's report withheld the identities of the affected vendors.

The vendors subsequently responded to the reports with their own official statements, which were printed in multiple reports.
