Researchers at Akamai reported on a Magecart skimmer campaign disguised as Google Tag Manager that also made the news with the compromise of one of Canada's largest liquor store (LCBO).

In this blog post, we show how the newly found Kritec skimmer was found along side one of its competitors. In fact, we saw instances of compromised stores having both skimmers loaded, which means double trouble for victims as their credit card information is stolen not just once but twice. In the listed indicators of compromise, we noticed domains that we had seen used in a distinct skimming campaign which didn't seem to be documented yet. Recently, while reading a blog post from security vendor Akamai, we spotted a similar situation. In the past, we have seen such occurrences with Magecart threat actors for example in the breach of the Umbro website. After all, if a vulnerability exists one can expect that it will be exploited more than once. Threat actors often compete for the same resources, and this couldn't be further from the truth when it comes to website compromises.
