I came across some interesting defacement pages recently and noticed a peculiar JavaScript injection included within each source code of the defaced websites. As shown below, this JavaScript injection was peculiar as it seemingly provided no benefit to the hacker:

<script>
	ANCHORFREE_VERSION = "623161526"

<script type='text/javascript'>
	var _AF2$ = {
    	'SN': 'HSSHIELD00TN',
    	'IP': '69.22.172.11',
    	'CH': 'HSSCNL000393',
    	'CT': '0',
    	'HST': '&sessStartTime=0&SFLAG=1&in=1423962910_84044764|d,1553137850|w,1553137850|m,1553137850|t&out=1423962910_23400718|d,305397307|w,305397307|m,305397307|t&NUM_VID=2&NUM_VID_TS=1423962310&bChrome=40&pv=5&clsBtnCnt=14&fav=8&fvidat=0&fvidv=0&accessLP=1',
    	'AFH': 'hss306',
    	'RN': Math.floor(Math.random() * 999),
    	'TOP': (parent.location != document.location || top.location != document.location) ? 0 : 1,
    	'AFVER': '3.69',
    	'fbw': false,
    	'FBWCNT': 0,
    	'FBWCNTNAME': 'FBWCNT_CHROME',
    	'NOFBWNAME': 'NO_FBW_CHROME',
    	'B': 'c',
    	'VER': 'nonus'
	};
	if (_AF2$.TOP == 1) {
    	document.write("<scr" + "ipt src='http[:]//box.anchorfree.net/insert/insert.php?sn=" + _AF2$.SN + "&ch=" + _AF2$.CH + "&v=" + ANCHORFREE_VERSION + 6 + "&b=" + _AF2$.B + "&ver=" + _AF2$.VER + "&afver=" + _AF2$.AFVER + "' type='text/javascript'></scr" + "ipt>");
	}

The injected javascript code contains some details from the client's connection to the HotSpot Shield VPN server, then runs a javascript file from box.anchorfree.net

Fake Font Dropper

2018-06-14  by  Moe Obaid

A website owner reached out to us to investigate a weird behavior on their site. It was randomly showing a popup window for a missing font and telling the visitors that they are unable to view the content of the site because their own computers are missing a required font by the website called “HoeflerText”, as shown in this screenshot:
