Is that all the information you have? No mention of what kind of job (if any) is being advertised? Is the domain name for a company that you recognize, or is ABC.com some mystery domain?

It sounds like some sleazebag recruiter is collecting resumes. I would just ignore an email / ad with no more information than that.

If you ever feel uncomfortable providing the information or that you don't have enough information before sending then don't. Better safe than sorry. If the company doesn't want to share enough information to make an informed decision- then what else will they withold.
