Notes on email unobfuscation

Email unobfuscation.md

CloudFlare

• Documentation

# http://www.conservative.ca/team/member/?fname=Arnold&lname=Viersen&type=candidates
span = page.xpath('//span[@class="__cf_email__"]/@data-cfemail')
code = span[0]
operand = int(code[:2], 16)
return ''.join(chr(int(code[i:i + 2], 16) ^ operand) for i in range(2, len(code), 2))

ExpressionEngine

• Documentation

The two examples pages below seem to run different versions of ExpressionEngine.

# http://nslegislature.ca/index.php/people/members/patricia_arab
script = page.xpath('//dd/script/text()')
if script:
    codes = reversed(re.findall(r"]='(.+?)'", script[0]))
    content = ''.join(char(code) for code in codes)
    return re.search(r'>(.+)<', content).group(1)

# https://www.chp.ca/candidates/bow-river
script = page.xpath('//span[@class="email"]/script/text()')
if script:
    codes = reversed(re.findall(r"[\[,]'(.+?)'", script[0]))
    content = ''.join(char(code) for code in codes)
    return re.search(r'>E: (.+)<', content).group(1)

Joomla

• Code

var = re.findall(r'var addy\d{4,5} = \'(.*)\'', script)[0].replace('\' + \'', '').replace('\'', '')
ext = re.findall(r'addy\d{4,5} = addy\d{4,5} \+ \'(.*);', script)[0].replace('\' + \'', '').replace('\'', '')
h = html_parser.HTMLParser()
return h.unescape(var + ext)
