A group of anti-ISIS Muslim hacktivists, "Daeshgram," has succeeded in breaking into ISIS news agency Amaq, and introducing fake news into Amaq's sites. Their goal, they say, is to contribute to the discrediting of ISIS by flooding Amaq users with bogus and scandalous, yet plausible, content. They have attempted to craft the fake news for believability (announcements that an ISIS radio station had been destroyed in an airstrike, things like that). ISIS handed Daeshgram a victory when it told followers not to trust links presented in Amaq.

ISIS struck a Sufi mosque in Egypt over the weekend, killing more than 300 worshippers, many of them children. An attack on a mosque is unusual for the terrorist group, but they've been denouncing Sufism online for some time.

Observers note with misgivings an increase in North Korean university training on blockchain technology. Recorded Future, for example, dismisses the notion that this is an innocent intellectual trend. Most see the training as a harbinger of more attempts to loot Bitcoin and other cryptocurrencies on behalf of the Pyongyang regime. Criminal interest in cryptocurrency theft is rising across the board. The SANS Institute has been blogging about an increase in scans for Bitcoin and Ethereum wallets.

Imgur, the image-sharing service, disclosed Friday that it had been hacked in 2014, losing some 1.7 million email addresses and passwords, probably to brute-forcing. Researcher Troy Hunt discovered the breach on Thursday and immediately informed Imgur. Their swift disclosure is being widely commended. (Detection, of course, was slow.)
