Currently I am looking for remote work in security and/or experimental mathematics.
SUMMARY I am security researcher and consultant and developer. Published some high profile security stuff. Can code in sagemath and python.
ACHIEVEMENTS
Over 110 security vulnerabilities, with over 50 CVE entries in widely used software (not counting contract work). Vulnerabilities range from remote kernel problems to browser bugs. Notable vulnerabilities:
Discoverer of DLL hijacking: design flaw in windows when loading dynamic libraries from current working directory, efficient exploit vector in malware. Disclosed in 2000, still alive till at least 2023. Source
The first expoitable qmail bugs Source
Remote root in Ubuntu via apt-key Source
Remote OpenBSD denial of service in IP6 (very rare) Source
Design flaw in windows when digitally signing buggy mobile code (ActiveX) Source
Design flaw in cryptography RFC about DH group parameters, LibreSSL fixed it Source
Publications received popular media coverage (CNN, cnet.com, theregister.co.uk) and are available on packetstormsecurity.com and www.exploit-db.com.
Over 50 CVEs google search. Some CVEs: qmail CVE-2005-1515 dll hijacking CVE-2000-0854 vim CVE-2000-0854 linux kernel CVE-2005-0530 openbsd remote crash CVE-2004-0257 apache mod_proxy cve-2004-0492 microsoft excel CVE-2002-0618
